Abstract

Introduction

Paradigm Shift from Open to Arthroscopic Surgery

For many years, the surgical management of shoulder disorders relied primarily on open techniques. Until the 1970s and 1980s, the standard procedure for rotator cuff tears required a deltoid muscle incision to expose the subacromial space for cuff suturing [5]. Similarly, open repair was the predominant method for addressing shoulder instability [6,24].

Arthroscopy was introduced in the 1980s as a diagnostic tool for shoulder disorders. By the mid-1990s, its application had expanded to therapeutic procedures, including subacromial decompression [5,7,8]. Following Snyder’s landmark report of arthroscopic rotator cuff repair in 1993, improvements in instruments and techniques, combined with growing surgeon expertise, accelerated the adoption of arthroscopic surgery in clinical practice [5,7].

Beginning in the late 1990s, innovations such as improved suture materials and the development of techniques like knotless fixation and double-row repair established arthroscopy not merely as a substitute for open surgery but as an independent therapeutic paradigm [5,10,25,26]. Early limitations—including inadequate instrumentation, restricted visualization, and limited surgical proficiency—contributed to high failure rates. Since the 2000s, however, greater surgical stability and reproducibility have markedly improved outcomes. Numerous studies have demonstrated that arthroscopic surgery results in lower re-tear rates and faster recovery than open repair [10,12–14,18].

The evolution of arthroscopic management for shoulder instability followed a similar trajectory. Early arthroscopic labral or capsular repairs were hindered by insufficient fixation and inadequate capsular tensioning. Subsequent advances in surgical techniques have substantially improved outcomes [6,11–13,27]. A major recent development has been the introduction of surgical decision-making criteria based on the presence of bone loss. This approach has broadened arthroscopic surgery beyond soft tissue repair, allowing for the simultaneous management of bone defects [6,11].

As surgical techniques advanced, the benefits of reduced postoperative pain and shorter rehabilitation became increasingly clear, driving the rapid popularization of arthroscopic surgery. Today, some procedures can even be performed on an outpatient basis without hospitalization [11,16,28]. This shift represents not just a change in technique but a fundamental transformation in the overall treatment paradigm for shoulder disorders.

A similar transition from open to arthroscopic surgery is also underway in the elbow. Initially, access was restricted due to the joint’s limited space and the proximity of critical neurovascular structures. However, accumulated surgical experience, equipment miniaturization, and improved knowledge of anatomical access routes have enabled arthroscopy to replace open approaches as a viable treatment for multiple elbow conditions, including epicondylitis, intra-articular loose bodies, synovitis, osteoarthritis, and plica syndrome [19,20,22,29–32]. In the case of epicondylitis, arthroscopic surgery offers the advantage of selectively removing degenerated tendon tissue from the origin of the extensor carpi radialis brevis (ECRB) through an intra-articular approach, thereby minimizing incision size and shortening recovery. This advantage is also fueling the use of arthroscopy for medial epicondylitis, osteoarthritis, and plica syndrome [21,33–35]. These developments suggest that arthroscopy may ultimately become the standard of care for elbow disorders.

Rotator Cuff Tears: Evolving Arthroscopic Treatment Strategies

Rotator cuff tears are among the most common shoulder disorders, particularly in middle-aged and older adults, and are a major cause of chronic pain, functional limitation, and nocturnal discomfort. The prevalence in Korea is estimated at approximately 7%, with incidence increasing substantially in older populations [2,3]. While most tears are degenerative, factors such as trauma and overuse also contribute [2].

For partial tears or cases with mild symptoms, conservative treatments, including medication, physical therapy, and injections, are often the first choice and can provide effective short-term relief [14]. However, as tears progress and fatty infiltration of the rotator cuff muscles develops, the likelihood of functional recovery declines, and the tear may become irreparable. Consequently, early surgical intervention is sometimes recommended, particularly for young and active patients [14,18].

Historically, open repair was the standard treatment for rotator cuff tears. From the mid-1990s, however, arthroscopic repair gained acceptance and is now the preferred method for most cases [5,7,9,11]. Arthroscopic repair provides advantages such as smaller incisions, less postoperative pain, and faster recovery compared with open surgery [13,18]. The adoption of advanced techniques, such as double-row repair and knotless fixation, has improved repair strength and biomechanical stability, contributing to lower re-tear rates [10,25,26].

In recent years, various arthroscopic treatment methods have been applied to extensive (massive) or difficult-to-repair (irreparable) tears. These include partial repair, tendon transfer, patch augmentation with allograft dermal matrix, and superior capsular reconstruction (SCR). The choice of technique is based on a comprehensive assessment of the patient's age, functional demands, and the presence of muscle atrophy and fatty infiltration [15,26,36,37].

Among these, SCR—first developed in Japan—initially attracted considerable attention. More recently, however, skepticism has grown due to relatively high mid- to long-term failure rates and its limited indications [15]. As a result, alternative strategies have been explored. While open rotator cuff advancement was once used, advances in technology have enabled all-arthroscopic antegrade supraspinatus advancement, which allows flexible release and advancement of the supraspinatus tendon to the greater tuberosity, thereby broadening the scope of arthroscopic repair [36].

If rotator cuff repair is not possible, tendon transfer remains a valid alternative. For challenging subscapularis tears, pectoralis major transfer was the traditional approach. This evolved into using the latissimus dorsi (LD). More recently, LD and teres major transfer has been proposed, which provides a more powerful and anatomically favorable force vector.

For irreparable tears of the posterosuperior cuff (supraspinatus and infraspinatus), partial repair was once the standard, but the LD transfer subsequently became the preferred option. More recently, lower trapezius transfer has received attention, as it provides superior biomechanical alignment and stabilization compared with the LD transfer. Technique selection is determined by lesion extent, patient functional demands, and anatomical considerations. Increasingly, an evidence-based framework guides the determination of indications, expected outcomes, and prognosis for each surgical option [38].

In conclusion, rotator cuff tear management must be tailored to both disease progression and patient-specific factors. Arthroscopic surgery has firmly established itself as the central modality within this treatment spectrum.

Evolution of Arthroscopic Surgery for Shoulder Instability

Shoulder instability is a major clinical condition that can significantly limit daily function. Its primary mechanism involves compromised joint stability due to recurrent dislocations or fatigue-related injuries [6].

This disorder typically arises in young, active individuals after a traumatic dislocation, with a high likelihood of progression to recurrent dislocations following the initial anterior episode. In the past, open repair of the labrum and capsule was the standard treatment. However, since the 1990s, the introduction of arthroscopic surgery has transformed the standard of care [6,8,13]. Early outcomes were hindered by high failure rates, largely attributable to limited instrumentation and incomplete techniques. Advances such as bioabsorbable fixation devices, the remplissage technique, and improved reconstruction techniques for Bankart lesions, have since led to markedly better surgical outcomes [6,11–13,27].

More recently, a tiered surgical strategy has been established that goes beyond soft tissue repair to address associated bone loss. In this approach, the extent of glenoid bone loss serves as the basis for selecting individualized surgical methods [6,11]. Numerous studies have also reported advantages of arthroscopy over open surgery, including smaller incisions, faster recovery, and better restoration of joint range of motion [12,13]. Moreover, recent evidence suggests that performing early arthroscopic surgery after an initial anterior dislocation can reduce recurrence rates, thereby expanding its clinical indications [27].

Arthroscopic Treatment for Adhesive Capsulitis of the Shoulder

Adhesive capsulitis, commonly referred to as “frozen shoulder,” is another major cause of functional limitation in daily life. Its hallmark mechanism is restricted joint motion due to capsular contracture and adhesion [39]. Typically seen in middle-aged and older individuals, adhesive capsulitis is characterized by pain and limited movement resulting from inflammation and fibrosis of the capsule, often without a clear traumatic trigger. Because the condition is usually self-limiting, conservative management—including medication, physical therapy, and steroid injections—is generally recommended as initial therapy and provides effective short-term symptom relief [39]. However, some patients develop chronic, debilitating symptoms or remain refractory to conservative management.

In cases with severe capsular fibrosis unresponsive to nonsurgical treatment, manipulation under anesthesia or capsular release may be indicated. Arthroscopic capsular release offers the advantage of precise, targeted release under direct visualization, thereby minimizing the risk of iatrogenic injury to adjacent structures and facilitating faster postoperative recovery [11,39]. Recent studies have confirmed the clinical benefits of arthroscopic release across multiple outcomes, including pain reduction, improved range of motion, and shorter rehabilitation time. Consequently, arthroscopic capsular release has become an effective treatment option for patients who do not respond to physical therapy or injections [39].

Arthroscopic Surgery for Fractures around the Shoulder

The use of arthroscopic techniques has recently expanded beyond soft tissue repair to include fractures of the scapula and humerus. In cases involving the articular surface or structures closely linked to the rotator cuff and acromioclavicular–coracoclavicular ligament complex, arthroscopic surgery allows anatomical reduction and minimally invasive fixation, resulting in favorable clinical outcomes [40,41].

For example, in cases of acromioclavicular joint dislocation, arthroscopic TightRope fixation has shown superior outcomes compared with traditional plate fixation, providing less postoperative pain, faster functional recovery, and fewer complications [42]. Similarly, for fractures of the humeral greater tuberosity, the arthroscopic double-row suture bridge technique can achieve anatomical reduction and stable fixation, which allows faster joint motion and strength recovery [40]. Recent reports have also described the use of arthroscopic techniques for treating anterior/posterior glenoid fractures, with procedures such as double-row suture repair achieving high fusion rates and excellent functional recovery [41].

Compared with open surgery, arthroscopic fracture management reduces the risk of infection, minimizes soft tissue damage, and allows earlier initiation of rehabilitation, collectively contributing to improved prognoses [40,41]. With further expansion of indications and standardization of surgical protocols, arthroscopy is expected to become an important alternative for treating both intra- and extra-articular shoulder fractures.

Arthroscopic Surgery as a Treatment Option for Septic Arthritis of the Shoulder Joint

The role of arthroscopic surgery has also expanded into infectious conditions. In particular, for septic arthritis of the shoulder—a condition more common in older patients—arthroscopic lavage and synovectomy have emerged as effective alternatives to traditional open arthrotomy [11]. The shoulder joint is especially amenable to arthroscopy due to its deep soft tissue coverage and large joint cavity, which allow easier access.

Kwon et al. [43] reported favorable outcomes in patients with shoulder septic arthritis treated by arthroscopic lavage, noting that aggressive lavage and synovectomy through multidirectional portals eliminated the need for repeat surgery. This approach provides clear visualization, facilitates complete removal of infected tissue, and helps preserve shoulder function. However, early diagnosis and timely surgical intervention remain critical, as infections in older or immunocompromised individuals can progress rapidly.

Thus, arthroscopic management of septic arthritis in the shoulder represents a less invasive, function-preserving alternative to open surgery, with benefits including faster recovery and lower reoperation rates [11]. This application highlights the growing potential of arthroscopy in the management of infectious joint diseases.

Arthroscopic Treatment for Epicondylitis of the Elbow: Minimally Invasive Strategies for Lateral and Medial Epicondylitis

Epicondylitis is a representative overuse injury caused by tendon degeneration from repetitive elbow activity, leading to significant discomfort in daily and occupational tasks. It is classified as lateral epicondylitis, or “tennis elbow,” affecting the outer elbow, and medial epicondylitis, or “golfer’s elbow,” affecting the inner elbow. Both forms are closely linked to repetitive wrist extension or flexion. Although many cases respond well to conservative therapy, surgery may be considered for patients with persistent pain and functional impairment lasting several months or longer [33,35,44].

Traditionally, surgical management involved open procedures to excise diseased tissue or directly release the tendon. However, arthroscopic surgery is increasingly favored because it minimizes invasiveness and accelerates recovery and functional restoration. For lateral epicondylitis in particular, arthroscopy provides significant benefits, as the lesion lies adjacent to the joint space and can be easily visualized and treated through intra-articular access [31,34,44].

The main arthroscopic technique involves debridement at the origin of the ECRB tendon, which is highly prone to degeneration from repetitive tensile forces and friction. Through joint entry, the surgeon can selectively excise the diseased tendon tissue or surrounding synovium, thereby addressing the primary pain source. In some cases, partial resection of the lateral capsule or bone drilling at the lesion site is performed to stimulate tendon reattachment [23,31,34]. Postoperatively, patients generally report less pain and minimal collateral damage, enabling rapid recovery; most return to normal daily activity within six weeks [34,44].

For medial epicondylitis, surgical access is more challenging due to anatomical constraints and the proximity of neural structures. Nonetheless, arthroscopic techniques have been developed to approach medial lesions, enabling resection of diseased tissue and, when necessary, partial capsule removal. Compared with traditional open medial procedures, this approach allows more precise and safer treatment, provided that anatomical landmarks are carefully identified to minimize the risk of nerve injury [33,35].

Recent systematic reviews and meta-analyses indicate that arthroscopic surgery achieves outcomes comparable to or better than open procedures, including reduced recurrence, improved pain relief, and high rates of return to sports [34,35]. An additional advantage of arthroscopy is the ability to simultaneously address coexisting intra-articular lesions, providing a more comprehensive therapeutic approach [19,22,45].

However, surgical success is highly dependent on operator expertise. Insufficient anatomical knowledge may result in complications such as nerve injury, especially in medial epicondylitis, where the ulnar nerve lies in close proximity. Therefore, preoperative localization with ultrasound or magnetic resonance imaging (MRI) is strongly recommended [33]. To further enhance safety and precision, adjunct technologies such as radiofrequency ablators, endoscopic nerve monitoring, and 3-dimensional (3D) image-guided systems are under active development. With continued refinement and standardization of techniques, arthroscopic treatment is expected to gain broader indications and play an expanding role in epicondylitis management [21,23,32].

Arthroscopic Surgical Strategies for Elbow Osteoarthritis and Plica Syndrome

The elbow is an anatomically compact joint housing numerous structures within a confined space. As a hinge joint responsible for flexion, extension, pronation, and supination, it is particularly vulnerable to pain and restricted motion caused by repetitive use, trauma, or inflammatory changes. Two representative conditions—elbow osteoarthritis and synovial plica syndrome—are considered prime indications for arthroscopy because they allow direct visualization and targeted treatment of localized pathology [21,22,29].

Elbow osteoarthritis is classified as primary or secondary. Primary disease is more common in active middle-aged men, whereas secondary osteoarthritis often arises from trauma or prior surgery. In its early stages, the disease is typically characterized by restricted end-range motion without significant pain. In advanced stages, however, osteophyte impingement, synovitis, intra-articular loose bodies, and progressive joint space narrowing may result in fixed contractures [20,29,30].

Arthroscopic surgery provides an effective, minimally invasive means of removing these lesions and restoring joint motion. Typically, anterior and posterior portals are used to excise osteophytes from the coronoid fossa anteriorly and the olecranon fossa posteriorly, while simultaneously resecting hypertrophic synovium or removing loose bodies [22,29,30]. For mild to moderate degenerative disease, arthroscopic debridement alone often achieves satisfactory pain relief and functional improvement. A major advantage compared to open arthroplasty is the quicker rehabilitation timeline, as patients can begin early mobilization soon after surgery [20,21]. In cases with severe contractures, arthroscopic capsular release may be performed, with technical modifications tailored to the location of adhesions, hypertrophied synovium, or pathological osteophytes. Expanding surgical indications and accumulating evidence now highlight low complication rates and favorable functional outcomes [21,30]. Nevertheless, for severe contractures or advanced osteochondral defects, open arthroplasty or total elbow arthroplasty may remain necessary [20].

A plica is a vestigial fold of synovial tissue present in most individuals. While usually asymptomatic, repetitive irritation or trauma can cause hypertrophy and fibrosis, leading to clinical symptoms. The radial plica, located near the radiocapitellar joint, may cause pain or a snapping sensation during flexion-extension or supination [45]. Clinically, plica syndrome is suggested by localized tenderness over the lateral joint line, pain aggravated by supination, and confirmation of hypertrophic synovium on ultrasound or MRI. Although it may occur spontaneously, it is more common among athletes such as baseball players and gymnasts who engage in repetitive elbow motion. Diagnosis is often delayed, particularly when plica syndrome coexists with epicondylitis [45,46].

Arthroscopic surgery provides both diagnosis and treatment in a single procedure. Standard treatment involves introducing a posterolateral portal to identify the lesion adjacent to the radial head, followed by excision of the hypertrophied plica using a radiofrequency ablator or shaver [21,45]. Most patients experience rapid symptom resolution and early return to activity, including sports participation.

As with other arthroscopic procedures, success depends on the surgeon’s technical skill and understanding of anatomical variations, particularly regarding nearby neural structures. Current research aims to improve preoperative assessment through MRI-based quantification of plica presence and thickness, thereby refining surgical indications. Increasing emphasis is being placed on integrated strategies that link imaging, diagnosis, and arthroscopic treatment into a cohesive clinical pathway [45,46].

Evolution of Arthroscopic Surgery for Elbow Sports Injuries and Instability

The elbow is subjected to repetitive and high-intensity stress in many sports, including baseball, gymnastics, judo, and weightlifting. Such stress often leads to injuries, particularly in pitchers and athletes performing repetitive weight-bearing movements. Resulting structural damage can range from simple overuse syndromes to more complex conditions such as ligamentous instability, synovitis, intra-articular loose bodies, and osteochondral lesions.

Historically, these sports-related injuries were managed with conservative therapy or open surgery. The advent of arthroscopic techniques has provided a valuable alternative, offering early diagnosis, targeted lesion removal, and functional restoration [19–21].

Among the most effective applications of arthroscopy in sports injuries is the management of elbow instability. This condition commonly involves injury to the ulnar collateral ligament (UCL) or posterolateral rotatory instability (PLRI). Such injuries are often caused by repetitive overuse—particularly throwing motions—rather than acute trauma. Severe cases typically require surgical treatment. While UCL reconstruction remains the gold standard, some reports indicate that partial tears or chronic inflammatory lesions can improve with arthroscopic debridement alone [21,22,47].

For PLRI, arthroscopy enables direct visualization of intra-articular lesions and allows diagnosis of damage to the lateral ulnar collateral ligament (LUCL), the key structure responsible for rotational stability. Previously, imaging studies made this condition difficult to detect, leading to delayed diagnosis. Arthroscopy now allows real-time observation of instability during pronation and supination, thereby improving diagnostic accuracy. Mild lesions may be treated with arthroscopic debridement and ligament repair, whereas severe instability still requires open reconstruction following arthroscopic diagnosis [21,22].

Intra-articular loose bodies and osteochondral defects, particularly common among athletes, are also prime indications for arthroscopy. Loose bodies in the radiocapitellar joint are a frequent source of pain, crepitus, and restricted motion. Arthroscopy allows accurate diagnosis and efficient removal of these lesions. From a sports medicine perspective, the reduced incision size and quicker recovery time are major advantages, enabling athletes to return to play more rapidly [20,21].

The scope of arthroscopic surgery in sports medicine is shifting from simple debridement toward functional restoration. Recent innovations include arthroscopic ligament repair, loose body removal, synovectomy, and regenerative procedures such as microfracture for osteochondral defects. Increasingly, surgical strategies are being tailored to the patient’s age, sport, and lesion location [21,46].

Another important role of arthroscopy in sports injuries lies in diagnosis and prognosis. It serves as a valuable tool for evaluating chronic pain or recurrent injuries of uncertain origin, as it allows direct visualization and treatment of subtle lesions, such as synovitis, cartilage injury, or small loose bodies, that may not be evident on MRI or ultrasound [19,22,46].

New Technologies and Prospects for Elbow Arthroscopy

For many years, elbow arthroscopy was considered highly challenging due to the joint’s narrow space, dense neurovascular structures, and limited visualization. Advances in instrumentation, improved surgical techniques, and greater anatomical understanding have now made elbow arthroscopy safer and more effective [21,23].

A significant recent milestone is the ability to perform procedures that were once exclusive to open surgery, such as nerve decompression and ligament reconstruction, through arthroscopic approaches. For example, cubital tunnel syndrome was traditionally managed with open ulnar nerve release or anterior transposition. Today, arthroscopic decompression is increasingly performed, providing a minimally invasive option that also enables simultaneous treatment of coexisting pathologies [32,47,48].

Ligament repair and reconstruction are also being explored arthroscopically. For LUCL injuries in PLRI, open reconstruction was long the standard. However, arthroscopy-assisted anchor repair is now being attempted, with growing numbers of clinical reports documenting its feasibility [23,31]. To safely standardize these advanced procedures, clear visualization of intra-articular lesions and precise identification of anatomical landmarks are essential. To meet these demands, new tools such as high-resolution endoscopes, wide-angle lenses, and flexible arthroscopes are being developed.

Elbow pathology is frequently multifactorial, with loose bodies, synovial hypertrophy, and cartilage injury often coexisting. This complexity has driven the exploration of artificial intelligence (AI)–based image analysis to quantify lesions and generate automated surgical plans. Current research is developing algorithms capable of diagnosing pathology and predicting outcomes from MRI or ultrasound, with the goal of integrating these with arthroscopic imaging for real-time surgical guidance and automated lesion detection [21,23].

Future prospects for elbow arthroscopy also include advances in education and training. Virtual reality surgical simulators now provide opportunities for repeated, skill-level–specific practice, improving preoperative planning and reducing complications. These tools are especially valuable in managing anatomically complex joints such as the elbow.

In summary, elbow arthroscopy is transitioning from a basic debridement procedure to a comprehensive strategy encompassing accurate diagnosis, minimally invasive treatment, functional restoration, and predictive rehabilitation. This transformation is being driven by technological innovation, improved instrumentation, and structured surgical training [21,23,47,48].

Current Trends and Prospects of Arthroscopic Surgery

Arthroscopic surgery has advanced from a simple diagnostic tool into a complex, precise therapeutic strategy tailored to the pathophysiology of each condition. Its scope continues to expand, even in areas once thought unsuitable for arthroscopy, such as difficult-to-repair rotator cuff tears. This progress is the product of converging mechanical, biologic, and digital innovations [11,28].

A representative example is SCR, initially regarded as a promising solution for massive and irreparable tears. More recently, however, SCR has undergone critical reevaluation due to uncertainties in long-term outcomes, procedural complexity, and limited indications [15]. Consequently, several alternative arthroscopic techniques have emerged. Patch augmentation with allograft dermal matrix has gained traction for its ability to preserve tendon function while providing structural support and promoting regeneration. Tendon transfer procedures, particularly in younger and more active patients, aim to restore function, with arthroscopic transfers using the LD, teres major, and lower trapezius undergoing continuous refinement [26]. In addition, supraspinatus advancement is being actively studied as a means of improving tendon tension, enhancing repair success rates, and promoting functional recovery [36].

Alongside these technical advances, biologic therapies are receiving increasing attention as adjuncts to arthroscopic surgery. Materials such as atelocollagen, polydeoxyribonucleotide, and platelet-rich plasma are being investigated for their potential to enhance tissue healing and reduce re-tear risk, with some already integrated into arthroscopic procedures [11,15]. Looking ahead, tissue-engineered grafts and controlled-release growth factor delivery systems are expected to see wider adoption.

The field is also moving toward personalized surgical planning. Detailed anatomical assessment using MRI and 3D computed tomography enables customized preoperative planning that incorporates lesion-specific and patient-specific factors. Simulation of arthroscopic portals, repair constructs, and fixation sites is becoming more common, with reports suggesting clinical benefits such as shorter surgical times, improved accuracy, and faster recovery [11].

Finally, the potential of AI-based analysis technology is a crucial factor in shaping the future of arthroscopic surgery. Current research is focused on image-based lesion analysis and suggesting suture placement guidance, but future applications are expected to extend to real-time intraoperative decision support and automated feedback on surgical technique [11,49,50].

In summary, the current trajectory of shoulder arthroscopy reflects a multifaceted convergence of mechanical refinements, biologic adjuncts, precise imaging analysis, and digital planning. Together, these innovations are driving expansion in the scope and success of arthroscopic procedures.

These technological advances are also rapidly influencing elbow arthroscopy. Once considered technically prohibitive due to its narrow joint space and complex anatomy, the elbow is now more accessible thanks to high-resolution cameras, wide-angle optics, and flexible arthroscopes [21,23,47,48]. Notably, arthroscopic release for cubital tunnel syndrome and arthroscopy-assisted ligament repair for posterolateral instability are increasingly recognized as minimally invasive alternatives to traditional open approaches [31,32,48]. Simulator-based arthroscopic training for the elbow is also being introduced, while next-generation technologies such as 3D navigation, augmented reality guidance, and AI-assisted image analysis are beginning to be applied. Together, these trends promise improved precision, safety, and predictability, signaling a promising future for arthroscopy in both the shoulder and elbow.

Conclusion

Arthroscopic surgery stands as a hallmark of progress in minimally invasive orthopedic treatment, with its role in managing shoulder disorders expanding dramatically. It has become the standard of care for conditions such as rotator cuff tears, shoulder instability, and adhesive capsulitis. By minimizing incision size and expediting recovery, arthroscopy has significantly improved patients’ ability to return to daily life [5,8,9,24]. As the prevalence of shoulder disorders rises in line with aging demographics and increased sports participation, the importance of arthroscopic techniques within healthcare continues to grow [3,6,12,39].

Recent innovations—including high-resolution arthroscopes, biologic suture materials, endoscopic nerve monitoring, and 3D navigation—combined with advances in preoperative and postoperative rehabilitation, have further improved surgical outcomes [4,25,28]. The evolution from simple lesion excision to an integrated approach encompassing functional restoration, pain reduction, return to sport, and enhanced quality of life reflects a new paradigm for arthroscopic surgery [7,10,16].

A similar trend is seen in elbow arthroscopy. Once deemed technically daunting, it is now successfully applied to a variety of conditions, including epicondylitis, osteoarthritis, sports injuries, and cubital tunnel syndrome, broadening its clinical indications [20,29,31,44]. The emphasis on minimally invasive strategies that seamlessly integrate diagnosis, treatment, and rehabilitation is establishing arthroscopy as a central element in the standard management of both shoulder and elbow disorders [11,21,23,24].

Ultimately, arthroscopic surgery continues to advance through disease-specific strategies, image-guided precision, and integration with emerging technologies. This trajectory highlights the importance of interdisciplinary collaboration in optimizing patient care. Expanding our understanding of the appropriate applications and future potential of arthroscopy will be key to further improving outcomes and quality of life for patients [2,11,13,28].
