Recurrent posterior shoulder instability after primary repair is uncommon, but presents a challenging clinical scenario. Most revisions in failed labral repair were associated with glenoid bone morphology related to critical bone loss, retroversion, or dysplasia. A variety of treatment options exist which include revision labral repair with or without capsular plication, glenoid osteotomy, humeral rotational osteotomy, or glenoid bone augmentation. No single technique has been shown to be superior and each technique has strengths and limitations...

Posterior shoulder instability is a distinct subcategory of shoulder instability with an incidence higher than previously reported. Pain is typically the primary complaint, with pathology due to repetitive microtrauma being more common that a specific traumatic event. If nonoperative treatment fails, arthroscopic posterior capsulolabral repair has been shown to result in excellent outcomes and return to sport, with American football players having the best outcomes and throwers being slightly less predictable...

Posterior glenohumeral instability represents a wide spectrum of pathoanatomic processes. A key consideration is the interplay between the posterior capsulolabral complex and the osseous anatomy of the glenoid and humeral head. Stability is dependent upon both the presence of soft tissue pathology (eg, tears to the posteroinferior labrum or posterior band of the inferior glenohumeral ligament, glenoid bone loss, reverse Hill Sachs lesions, and pathologic glenoid retroversion or dysplasia) and dynamic stabilizing forces...

There has been growing interest in the rehabilitation process and timing of returning an athlete to sport following the management options for anterior shoulder instability. The purpose of this article is to review the current rehabilitation and return to sport (RTS) protocols for various nonoperative and operative management strategies following anterior shoulder instability events. When appropriate in the rehabilitation protocol, RTS testing should be criteria based, rather than time based, with a special focus given to psychological readiness in order to promote successful return to athletics and prevention of recurrent instability episodes in the future...

Overhead athletes with anterior, posterior, and multidirectional shoulder instability present with a wide range of symptoms, especially considering the injury mechanism and affected supportive structures. As such, the management of shoulder instability is widely variable and relies on rehabilitation, operative management, and sport-specific considerations, such as positional and seasonal demands on the athlete. Biomechanical analysis may further aid in the recovery process or serve as a predictive tool to identify an increased risk for injury...

The indications for bone block augmentation of the glenoid following recurrent anterior shoulder instability are expanding. Arthroscopic anatomic glenoid reconstruction (AAGR) is an evolving technique with similar clinical results to the Latarjet procedure and other open bone block procedures. Multiple types of bone grafts and fixation techniques have been described, with varying results on bony integration, resorption, articular congruity, and recurrence rates. This review focuses on biomechanics, patient workup, indications, current evidence, and the authors' preferred surgical technique for AAGR...

Utilizing fresh distal tibia allograft in anterior glenoid reconstruction has emerged as a highly advantageous approach in addressing instances of failed anterior shoulder stabilization with glenoid bone loss. This procedure offers several benefits, including the absence of donor-site morbidity, restoration of significant glenoid defects, reestablishment of joint congruity with the humeral head, restoration of glenoid biomechanics, and the addition of cartilage to the glenoid. Furthermore, it provides a robust and reliable alternative for managing failed stabilization procedures, leading to improved clinical outcomes and a high graft healing rate, while maintaining a low occurrence of recurrent instability...

In young athletes, anterior shoulder instability is a prevalent condition. Because of high-energy traumas, contact athletes often suffer recurrent instability, bone loss and postoperative recurrences. Patients younger than 20 years, symptomatic for more than 6 months, with ≥ 2 dislocations, with off-track Hill-Sachs lesion, glenoid bone loss, ALPSA lesion, Instability Severity Index Score > 3, and Glenoid Track Instability Management Score > 3 are at higher risk of failure. In cases of multiple dislocations with critical or subcritical glenoid bone loss, notably in collision and contact athletes, the Latarjet procedure is widely recognized as the treatment of choice...

Historically considered the gold standard technique for glenohumeral instability, the open Bankart repair is being performed at decreased rates because of the current trends favoring arthroscopic Bankart repair and the lack of consistent training of the open technique. However, open Bankart repairs may be more appropriate for certain high-risk populations (ie, high-level collision athletes) because of their reduced recurrent instability rates. Further investigations are needed to identify the indications for arthroscopic versus open Bankart repair and compare their outcomes in high-level athletes...

Anterior glenohumeral instability is one of the most common injuries suffered from sport. Despite padding and conditioning, the shoulder joint remains particularly vulnerable to injury, especially in the setting of contact. The overall rate of anterior instability is reported to be 0.12 injuries per 1000 athlete exposures, although this is increased up to 0.40 to 0.51 in the contact athlete. Successful treatment requires consideration of restoring stability while minimizing loss of glenohumeral motion. Common treatment strategies involve addressing the pathology that results from anterior shoulder dislocation including labral detachment as well as bony defects to the humeral head and glenoid...

In-season management of anterior shoulder instability in athletes is a complex problem. Athletes often wish to play through their current season, though recurrent instability rates are high, particularly in contact sports. Athletes are generally considered safe to return to play when they are relatively pain-free, and their strength and range of motion match the uninjured extremity. If an athlete is unable to progress toward recovering strength and range of motion, surgical management is an option, though this is often a season-ending decision...

In the evaluation of shoulder instability, recognition of relevant pathology on imaging is critical to planning a surgical treatment that minimizes the risk for recurrent instability. The purpose of this review is to (1) discuss the use of radiography, computed tomography, and MRI in evaluating shoulder instability and (2) demonstrate how various imaging modalities are useful in identifying critical pathologies in the shoulder that are relevant for treatment.

Shoulder glenohumeral joint dislocations and subluxations are a relatively common injury among athletic populations. Evaluating the patient both on the field initially and through early recovery helps to determine the best treatment strategies and predict the natural history of each unique injury.

The glenohumeral joint is the least congruent and least constrained joint with a complex relationship of static and dynamic stabilizers to balance its native mobility with functional stability. In the young athlete, anterior shoulder instability is multifactorial and can be a challenge to treat, requiring a patient-specific treatment approach. Surgical decision-making must consider patient-specific factors such as age, sport activity and level, underlying ligamentous laxity, and goals for return to activity, in addition to careful scrutiny of the underlying pathology to include humeral and glenoid bone loss and surrounding scapular bone morphology...

Precision anterior cruciate ligament reconstruction (ACLR) refers to the individualized approach to prerehabilitation, surgery (including anatomy, bony morphology, and repair/reconstruction of concomitant injuries), postrehabilitation, and functional recovery. This individualized approach is poised to revolutionize orthopedic sports medicine, aiming to improve patient outcomes. The purpose of this article is to provide a summary of precision ACLR, from the time of diagnosis to the time of return to play, with additional insight into the future of ACLR...

Rehabilitation after an anterior cruciate ligament (ACL) reconstruction requires patience, devotion, and discipline. Rehabilitation should be individualized to each patient's specific need and sport. Return to sport is a continuum throughout the rehabilitation, and patients should not return to performance before passing a battery of muscle function tests and patient-reported outcomes, as well as change of direction-specific tests. Return to full participation should be an agreement between the patient, physical therapist, surgeon, and coach...
