Abstract
BACKGROUND Large, circumferential glenoid labral tears are an uncommon injury affecting young, athletic patients. There are limited data describing the clinical presentation of patients with larger tears, especially 270° and 360° labral tears. Additionally, examination and imaging findings have poor reliability in diagnosing these tears. The purpose of this study was to determine the clinical presentation among patients presenting with small (less than 180°), medium (180°-270°), and large (270°-360°) labral tears. METHODS This is a retrospective comparative study of consecutive patients surgically managed by a single shoulder surgeon for all glenoid labral tears from 2018-2022. The primary outcome was demographic and preoperative clinical risk factors. Demographic data including age, sex, hand dominance, body mass index, as well as clinical presentation (subluxation vs. dislocation, instability history, and participation in contact sports) were recorded. RESULTS A total of 188 patients met the inclusion criteria: 101 of 188 (53.70%) patients with small tears, 43 of 188 (22.90%) patients with medium tears, and 44 of 188 (23.40%) patients with large tears. Individuals with large and medium-sized labral tears were more likely to have participated in contact sports compared to those with smaller labral tears (P = .003). Medium and smaller tears were more likely to present as dominant-side injury (P = .02). Furthermore, medium and large tears were more likely to present with anterior instability symptoms compared with smaller tears, which more frequently presented with posterior instability and pain (P = .003). CONCLUSION Males participating in contact sports were the most common demographic population presenting with large, 270°-360° labral tears. Instability was the primary complaint rather than pain, and compared with small tears, medium and large tears were more likely to present with primary anterior instability. Although arthroscopic repair of 270°-360° labral tears can yield excellent clinical outcomes similar to smaller tears, identifying factors associated with larger glenoid labral tears may help in surgical planning and patient counseling.

Orthop J Sports Med 2023; 11:23259671231151418. [PMID: 36896097 PMCID: PMC9989405 DOI: 10.1177/23259671231151418] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2022] [Accepted: 11/09/2022] [Indexed: 03/11/2023] Open
Abstract
Background All-suture anchors have been used for primary arthroscopic Bankart repair because of their ability to minimize initial bone loss. Purpose To evaluate the clinical efficacy of using all-suture anchors in revision arthroscopic labral repair after failed Bankart repair. Study Design Case series; Level of evidence, 4. Methods Enrolled in this study were 28 patients who underwent revision arthroscopic labral repair with all-suture anchors after a failed primary arthroscopic Bankart repair. Revision surgery was determined for patients who had a frank redislocation history with subcritical glenoid bone loss (<15%), nonengaged Hill-Sachs lesion, or off-track lesion. Minimum 2-year postoperative outcomes were evaluated using shoulder range of motion (ROM), the Rowe score, the American Shoulder and Elbow Surgeons (ASES) score, apprehension, and the redislocation rate. Postoperative shoulder anteroposterior radiographs were assessed to evaluate arthritic changes in the glenohumeral joint. Results The mean patient age was 28.1 ± 6.5 years, and the mean time between primary Bankart repair and revision surgery was 5.4 ± 4.1 years. Compared with the number of suture anchors used in the primary operation, significantly more all-suture anchors were inserted in the revision surgery (3.1 ± 0.5 vs 5.8 ± 1.3, P < .001). During the mean follow-up period of 31.8 ± 10.1 months, 3 patients (10.7%) required reoperation because of traumatic redislocation and symptomatic instability. Of patients with symptoms that did not require reoperation, 2 patients (7.1%) had subjective instability with apprehension depending on the arm position. There was no significant change between preoperative and postoperative ROM. However, ASES (preoperative: 61.2 ± 13.3 to postoperative: 81.4 ± 10.4, P < .01) and Rowe (preoperative: 48.7 ± 9.3 to postoperative: 81.7 ± 13.2, P < .01) scores were significantly improved after revision surgery. Eight patients (28.6%) showed arthritic changes in the glenohumeral joint on final plain anteroposterior radiographs. Conclusion Revision arthroscopic labral repair using all-suture anchors demonstrated satisfactory 2-year clinical outcomes in terms of functional improvement. Postoperative stability was obtained in 82% of patients without recurrent shoulder instability after failed arthroscopic Bankart repair.

Abstract
Anterior shoulder instability is the most frequent type of glenohumeral instability, especially among young athletes. Superior labral anterior-posterior (SLAP) injuries involve the superior glenoid labrum where the long head of the biceps tendon (LHBT) inserts. There is still some debate regarding the pathogenesis, clinical presentation, and treatment of these lesions. We report a clinical case of an 18-year-old male professional football player with a rare type IX SLAP lesion. Given the recurrence of instability after prior nonoperative management, surgical treatment was seen as the best option, and a pan-labral arthroscopic repair suture anchor fixation was performed. Three months after undergoing a personalized postoperative rehabilitation program, he was able to return to full sport with the same competitive level, and no recurrent instability or other symptoms were reported throughout the 18-month follow-up period.

Abstract
BACKGROUND Active-duty servicemembers are a population at risk for the development of posterior shoulder instability. While short-term outcomes after arthroscopic posterior labral repair for posterior shoulder instability are promising, there is a paucity of longer term follow-up data for this procedure. PURPOSES The primary purpose was to report midterm outcomes after arthroscopic posterior labral repair in active-duty military patients for posterior shoulder instability without bone loss. The secondary purpose was to determine if outcomes varied between anchor types used. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Preoperative and postoperative outcomes, with a minimum 3-year follow-up, for a visual analog scale for pain, the Single Assessment Numeric Evaluation (SANE), the American Shoulder and Elbow Surgeons (ASES) score, and the Rowe score were collected and analyzed. A separate subgroup analysis was performed comparing the outcomes of patients who underwent repair with biocomposite anchors versus those who underwent repair with all-suture anchors. RESULTS A total of 73 patients with a mean follow-up of 82.55 ± 24.20 months met the inclusion criteria and were available for analysis. As a whole, the cohort demonstrated statistically and clinically significant improvements in outcome scores at final follow-up. Preoperative and postoperative range of motion did not vary significantly. While the difference in final outcome scores between the 2 anchor types did not reach statistical significance, a statistically significantly larger proportion of patients who underwent repair with all-suture anchors versus those who underwent repair with biocomposite anchors met the Patient Acceptable Symptom State for the SANE (97.14% vs 78.95%, respectively; P = .0180) and the ASES score (88.57% vs 68.42%, respectively; P = .0171). The proportion of patients who achieved the substantial clinical benefit or surpassed the minimal clinically important difference, however, did not vary by anchor type. Overall, 70 patients (95.89%) remained on active duty and were able to return to preinjury work and recreational activity levels. There were 3 patients (4.11%) who had recurrent posterior instability. CONCLUSION This population of active-duty servicemembers undergoing posterior labral repair for posterior labral instability without bone loss demonstrated a statistically and clinically significant improvement in midterm outcomes, a low recurrence rate, and a rate of return to active duty of 95.89%, regardless of the anchor type used.

Abstract
OBJECTIVE To summarize the relationship between shoulder instability and superior labrum anterior posterior (SLAP) lesion. METHODS The characteristics of shoulder instability and SLAP lesion were analyzed, and the relationship between them in pathogenesis, clinical symptoms, and biomechanics was discussed by referring to relevant domestic and foreign literature. RESULTS Shoulder instability and SLAP lesion can occur both spontaneously and respectively. SLAP lesion destroys the superior labrum integrity and the long head of biceps tendon (LHBT) insertion, causing excessive humeral head displacement against glenoid, and leading to shoulder instability. While chronic repetitive or acute high-energy traumatic shoulder instability can in turn aggravate SLAP lesion, resulting in expansion and increased degree of the original lesion. CONCLUSION SLAP lesion destroys mechanisms of shoulder stability, while shoulder instability causes tears of the upper labrum and the LHBT, showing a connection between shoulder instability and SLAP lesion. However, the existing evidence can only demonstrate that shoulder instability and SLAP lesion induce and promote the development of each other, instead of a necessary and sufficient condition. Therefore, the specific causal relationship between the two remains unknown and needs to be further studied.

Abstract
BACKGROUND There is a high prevalence of combined shoulder instability in military patients. Short-term outcomes after 270° labral repair are promising; however, there is a paucity of longer term outcome data in this high-demand group of patients. PURPOSE To report the midterm outcomes of active-duty military patients treated with 270° labral repair for combined shoulder instability. STUDY DESIGN Case series; Level of evidence, 4. METHODS All consecutive patients between January 2011 and January 2019 who underwent 270° labral repair by the senior surgeon with complete outcome scores were identified. All patients had experienced a shoulder dislocation after a traumatic event and had magnetic resonance imaging and intraoperative findings consistent with combined-type instability. A total of 52 patients met the inclusion criteria for the study, and all were active-duty servicemembers at the time of surgery. RESULTS The mean follow-up was 78.21 months (range, 24-117 months). There was a statistically significant increase in the mean American Shoulder and Elbow Surgeons score (from 44.92 to 89.31; P < .0001), Single Assessment Numeric Evaluation score (from 52.32 to 93.17; P < .0001), and Rowe instability score (from 46.63 to 91.35; P < .0001) from preoperatively to postoperatively. Mean pain decreased significantly as measured by the visual analog scale for pain (from 8.04 to 1.44; P < .0001). Range of motion in forward flexion (from 155.29° to 155.96°; P = .6793), external rotation (from 67.50° to 65.29°; P = .0623), and internal rotation (from T9.58 to T9.56; P = .9650) did not change significantly postoperatively. Outcomes did not differ significantly for patients who underwent surgery on their dominant shoulder versus those who underwent surgery on their nondominant shoulder, nor did outcomes vary with the type of anchor utilized (biocomposite vs all-suture). The overall rate of return to active duty was 92.31%. CONCLUSION Midterm outcomes in this population of active-duty patients undergoing 270° labral repair for combined shoulder instability demonstrated a statistically and clinically significant improvement in patient-reported outcome scores, a significant decrease in pain, and an overall rate of return to active duty of 92.31%.

Abstract
BACKGROUND Current literature reports highly satisfactory short- and midterm clinical outcomes in patients with arthroscopic 270° labral tear repairs. However, data remain limited on long-term clinical outcomes and complication and redislocation rates in patients with traumatic shoulder instability involving anterior, inferior, and posterior labral injury. PURPOSE To investigate, at a minimum follow-up of 10 years, the clinical outcomes, complications, and recurrent instability in patients with 270° labral tears involving the anterior, inferior, and posterior labrum treated with arthroscopic stabilization using suture anchors. STUDY DESIGN Case series; Level of evidence, 4. METHODS A retrospective outcomes study was completed for all patients with a minimum 10-year follow-up who underwent arthroscopic 270° labral tear repairs with suture anchors by a single surgeon. Outcome measures included pre- and postoperative Rowe score, American Shoulder and Elbow Surgeons (ASES) score, Simple Shoulder Test, visual analog scale for pain, and Single Assessment Numeric Evaluation (SANE). Western Ontario Shoulder Instability Index (WOSI) scores were collected postoperatively. Complication data were collected, including continued instability, subluxation or dislocation events, and revision surgery. Failure was defined as any cause of revision surgery. RESULTS In total, 21 patients (mean ± SD age, 27.1 ± 9.6 years) with 270° labral repairs were contacted at a minimum 10-year follow-up. All outcome measures showed statistically significant improvements as compared with those preoperatively: Rowe (53.9 ± 11.4 to 88.7 ± 8.9; P = .005), ASES (72.9 ± 18.4 to 91.8 ± 10.8; P = .004), Simple Shoulder Test (8.7 ± 2.4 to 11.2 ± 1.0; P = .013), visual analog scale (2.5 ± 2.6 to 0.5 ± 1.1; P = .037), and SANE (24.0 ± 15.2 to 91.5 ± 8.3; P = .043). The mean postoperative WOSI score at minimum follow-up was 256.3 ± 220.6. Three patients had postoperative complications, including a traumatic subluxation, continued instability, and a traumatic dislocation, 2 of which required revision surgery (14.2% failure rate). CONCLUSION Arthroscopic repairs of 270° labral tears involving the anterior, inferior, and posterior labrum have highly satisfactory clinical outcomes at 10 years, with complication and redislocation rates similar to those reported at 2 years. This suggests that repairs of extensile labral tears are effective in restoring and maintaining mechanical stability of the glenohumeral joint in the long term.

Abstract
Purpose Development and validation of an animal model of labral healing would facilitate translation of novel surgical and biological strategies to improve glenolabral healing. The purpose of this study was to characterize the anatomic and histological properties of the shoulder labrum in rat, rabbit, dog, pig, goat, and humans. Given the demonstrated similarities in size and structural morphology in other joints, it was hypothesized that the goat glenoid with surrounding capsulolabral complex would most closely resemble that of humans in terms of dimensions and structure, as observed grossly and histologically. Methods Cadaveric glenohumeral joints from rats (n = 8), New Zealand white rabbits (n = 13), Mongrel dogs (n = 9), Spanish goats (n = 10), Yorkshire pigs (n = 10), and humans (n = 9) were freshly harvested. Photographs were taken of the glenoid with its surrounding capsulolabral complex. Linear dimensions of the glenoid articular surface were measured. It was determined where the capsulolabral complex was continuous with, or recessed from, the articular glenoid surface. The glenoid was divided into 6 equal segments radiating out toward 12, 2, 4, 6, 8, and 10 o’clock positions. Samples were sectioned and stained with Safranin O/Fast green and Mallory Trichrome. Insertion of the capsulolabral tissue onto the glenoid was qualitatively assessed and compared with gross morphology. Results Dimensions of the goat glenoid most closely paralleled dimensions of the human glenoid. A capsulolabral complex was continuous with the glenoid surface from ~ 9 to 12 o’clock in the rats, 7 to 12 o’clock in rabbits, 5 to 12 o’clock in the dogs, and 9 to 12 o’clock in goats, 6 to 12 o’clock in pigs, and 2 to 8 o’clock in humans. In contrast to humans, no other species demonstrated an organized fibrocartilaginous labrum either macroscopically or histologically. Conclusion The animals in the present study did not possess a discrete fibrocartilaginous labrum by gross or histological evaluation, as directly compared to humans. While models using these animals may be acceptable for examining other shoulder pathologies, they are not adequate to evaluate labral pathology.

Abstract
PURPOSE To identify factors predictive of a large labral tear at the time of shoulder instability surgery. METHODS As part of the Multicenter Orthopaedic Outcomes Network (MOON) Shoulder Instability cohort, patients undergoing open or arthroscopic shoulder instability surgery for a labral tear were evaluated. Patients with >270° tears were defined as having large labral tears. To build a predictive logistic regression model for large tears, the Feasible Solutions Algorithm was used to add significant interaction effects. RESULTS After applying exclusion criteria, 1235 patients were available for analysis. There were 222 females (18.0%) and 1013 males (82.0%) in the cohort, with an average age of 24.7 years (range 12 to 66). The prevalence of large tears was 4.6% (n = 57), with the average tear size being 141.9°. Males accounted for significantly more of the large tears seen in the cohort (94.7%, P = .01). Racquet sports (P = .01), swimming (P = .02), softball (P = .05), skiing (P = .04), and golf (P = .04) were all associated with large labral tears, as was a higher Western Ontario Shoulder Instability Index (WOSI; P = .01). Age, race, history of dislocation, and injury during sport were not associated with having a larger tear. Using our predictive logistic regression model for large tears, patients with a larger body mass index (BMI) who played contact sports were also more likely to have large tears (P = .007). CONCLUSIONS Multiple factors were identified as being associated with large labral tears at the time of surgery, including male sex, preoperative WOSI score, and participation in certain sports including racquet sports, softball, skiing, swimming, and golf.

Abstract
Labrum tears involving >270° of the glenoid have been termed "circumferential tears," "panlabral tears," "triple lesions," and "large tears." They are rare injuries that encompass anywhere from 2.4% to 6.5% of traumatic labral injuries. Given their rare nature, the literature has been limited to level IV studies with small patient numbers. Identifying these injuries in the clinical setting can be challenging, as patients can present with signs and symptoms of unidirectional instability, combined instability, or even microinstability. However, we know that magnetic resonance arthrography seems to be more helpful than magnetic resonance imaging, and that these patients will most often present with pain in between multiple instability episodes. Given that the gold standard treatment for these injuries is operative intervention, recognizing them as opposed to an isolated unidirectional injury is critical for surgical planning and patient counseling purposes. Isolating other demographic and historical risk factors in addition to physical examination and imaging may be key in making the diagnosis.

The Incidence of Posterior and Combined AP Shoulder Instability Treatment with Surgical Stabilization Is Higher in an Active Military Population than in the General Population: Findings from the US Naval Academy. Clin Orthop Relat Res 2021; 479:704-708. [PMID: 33094964 PMCID: PMC8083805 DOI: 10.1097/corr.0000000000001530] [Citation(s) in RCA: 28] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2020] [Accepted: 09/18/2020] [Indexed: 01/31/2023]
Abstract
BACKGROUND Anterior instability has consistently been shown to be the most common type of glenohumeral instability. Recent studies have demonstrated a higher percentage of posterior and combined (anterior and posterior) instability than had previously been reported; however, this work has not been replicated recently in a particularly young military population, which may be representative of an especially athletic or high-demand group. QUESTION/PURPOSE What proportion of arthroscopic shoulder stabilization procedures are performed to address isolated anterior instability, isolated posterior instability, and combined instability in a young, military population? METHODS Between August 2009 and January 2020, two sports medicine fellowship-trained surgeons performed arthroscopic shoulder surgery on 543 patients at a single institution. During that time, the indication to be treated with arthroscopic stabilization surgery was symptomatic glenohumeral instability, as diagnosed by the operative surgeon, that restricted patients from carrying out their military duties. Of those, 82% (443 of 543) could be evaluated in this retrospective study, while 18% (100 of 543) were excluded due to either incomplete data or because the procedure performed was not to address instability. No patient underwent an open stabilization procedure during this period. Of the 443 patients investigated, the mean age was 22 ± 4 years, and 88% (392 of 443 patients) were men. Instability type was characterized as isolated anterior, isolated posterior, or combined (anterior and posterior) according to the physician's diagnosis as listed in the patient's clinical records and operative reports after the particular capsulolabral pathology was identified and addressed. RESULTS Isolated anterior instability occurred in 47% of patients (210 of 443). Isolated posterior instability happened in 18% of patients (80 of 443), while combined anteroposterior instability occurred in 35% of patients (153 of 443). CONCLUSION Shoulder instability is common in the military population. Although anterior instability occurred most frequently, these findings demonstrate higher proportions of posterior and combined instability than have been previously reported. Surgeons should have a heightened suspicion for posterior and combined anteroposterior labral pathology when performing arthroscopic stabilization procedures to ensure that these instability patterns are recognized and treated appropriately. The current investigation examines a unique cohort of young and active individuals who are at particularly high risk for instability and whose findings may represent a good surrogate for other active populations that a surgeon may encounter.Level of Evidence Level III; therapeutic study.

Risk Factors for Failure of Nonoperative Treatment of Posterior Shoulder Labral Tears on Magnetic Resonance Imaging. Mil Med 2021; 185:e1556-e1561. [PMID: 32601668 DOI: 10.1093/milmed/usaa122] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2020] [Revised: 05/17/2020] [Accepted: 05/18/2020] [Indexed: 01/29/2023] Open
Abstract
INTRODUCTION There are no reports in the literature describing risk factors for failure of nonoperative treatment of patients with posterior labral tears on magnetic resonance imaging (MRI). The purpose of this study is to identify risk factors for failure of nonoperative treatment in patients with an isolated posterior glenoid labral tear identified on MRI only. Patients with posterior labral tears on MRI who fail to improve with nonoperative treatment likely share a constellation of clinical history, physical exam, and radiographic findings. METHODS One hundred and fifty-nine active duty military service members under the age of 40 with a posterior labral tear seen on MRI and who were clinically evaluated by a musculoskeletal trained physician were identified. We retrospectively evaluated their records ensuring a minimum of 2 years follow-up after MRI to identify surgical intervention for the posterior labral tear during this time period. Patients were stratified into two groups, those treated with any combination of nonoperative modalities and those treated with posterior labral repair surgery during the 2 years after the MRI. The electronic medical records were reviewed for clinical presentation and physical exam results. We measured multiple radiographic parameters, including glenoid version, size of the tear, and bone loss on MRI. Qualitative and quantitative data were compared between groups using Fisher's exact test and Student's t-test, respectively. This study was conducted under institutional review board approval. RESULTS Of the 157 patients' shoulders in our study, 52% (n = 82) of patients with posterior labral tears underwent nonoperative treatment while 48% (n = 75) underwent surgery. The significant risk factors associated with surgery were a history of a specific injury, primary presenting complaint of instability, patient reported history of subluxation, inability to trust their shoulder with overhead activity, decreased strength with weight lifting, positive posterior load/shift exam, positive anterior apprehension, increased osseous glenoid retroversion, increased humeral head subluxation ratio, and anterior labral height (P < 0.05). Patients with a chief complaint of pain were much more likely to succeed with nonoperative treatment while those with instability underwent surgery more often. Ten (12.5%) of the surgical procedures included an anterior and posterior labral repair/stabilization procedure. CONCLUSION Patients with an MRI confirmed posterior labral tear, which present with subjective complaints and physical exam maneuvers consistent with instability, appear less likely to be treated nonoperatively. Increased glenoid retroversion and posterior humeral head subluxation may also predispose patients toward surgical treatment. Additionally, posterior labral tears may extend into the anterior labrum more frequently than is recognized on MRI.

Abstract
Traumatic posterior dislocations of the shoulder can result in bony defects, labral tears, and cartilage injuries of the glenohumeral joint. Although traditional Hill-Sachs lesions from anterior dislocations are more commonly identified, reverse Hill-Sachs lesions caused by posterior dislocation often leads to recurrent engagement of the humeral head with the glenoid and significantly greater damage to the humeral chondral surface. In severe traumatic cases, concomitant damage of the capsulolabral soft tissues, such as circumferential labral lesions, can lead to chronic shoulder instability and residual glenoid bone loss. These lesions further add to the complexity of managing patients with posterior dislocations of the shoulder because of the challenges of achieving adequate anatomic reduction and tensioning of the capsulolabral junction, while also using a combination of arthroscopic and open-labral repair techniques. In the setting of reverse Hill-Sachs lesions treatment, it is important to address the bony and cartilage defect. The purpose of this Technical Note is to describe our preferred technique for arthroscopic repair of circumferential lesions of the glenoid labrum causing multidirectional instability with concomitant reverse Hill-Sachs Lesion treatment with fresh talus osteochondral allograft.

Abstract
Arthroscopic shoulder stabilization offers a safe and effective means for restoring glenohumeral mechanics in the setting of shoulder instability. Modern arthroscopic techniques have allowed improved access and efficiency when treating patients with shoulder instability. However, access to certain areas of the labrum and the creation of safe accessory portals can still prove difficult for the arthroscopic surgeon. Currently, there is debate as to the ideal patient position, portal location, equipment, and technique for addressing anterior-inferior labral pathology. The following article presents a safe and effective approach to accessing the labrum for treatment of shoulder instability in the lateral decubitus position. In addition, this paper highlights the use of accessory portals, including a percutaneous "7-o'clock" portal for suture anchor placement, along with multiple types of suture anchor and suture shuttling techniques.

Abstract
The hypermobility of the glenohumeral joint accounts for its anatomic predisposition for instability and dislocation. The stability of the shoulder joint is dependent on static and dynamic soft tissue structures, among which is the labrum. Circumferential labral tears are a rare pathological entity of shoulder instability that have not been commonly reported in the literature. A detailed history and physical examination are crucial for accurate diagnosis since MRIs have a poor sensitivity. A 40-year-old male patient with a history of atraumatic recurrent left shoulder subluxations for 6 years. On physical examination, there was no evidence of motor or sensory deficit. MR images were suggestive of Hills-Sachs lesion with intact rotator cuffs. Pan-labral tear repair via arthroscopy presents a unique challenge, even for the skilled orthopedic surgeon. Hence, the repair demands accessory portals and percutaneous techniques for the adequate placement of anchors. The purpose of this case is the rare presentation of a pan-labral tear repaired arthroscopically.

Abstract
PURPOSE To evaluate preoperative diagnostic rates for panlabral tear using imaging studies or physical examinations and to evaluate clinical outcomes after arthroscopic stabilization procedures with 2 different patient surgical positions. METHODS Patients who underwent arthroscopic stabilization for recurrent anterior shoulder instability with panlabral tear and were followed up for at least 2 years were included. A panlabral tear was defined as labral tear involving at least 270° of the glenoid surface on arthroscopic examination. All patients underwent preoperative magnetic resonance (MR) imaging or MR arthrography and physical examinations including anterior apprehension, posterior jerk, and compressive rotation tests. The clinical outcomes were assessed by the American Shoulder and Elbow Surgeons, Rowe, and visual analog scale for pain scores, and recurrence rate. According to patient position during surgery, patients were divided into group I (beach chair position) and group II (lateral decubitus position). RESULTS Forty-eight patients (24 in group I and 24 in group II) were enrolled. Preoperative MR imaging or MR arthrography detected only 18.8% of panlabral tears. No patient had positive findings on all 3 physical examination tests for panlabral tear. Clinical outcomes were significantly improved after operation (American Shoulder and Elbow Surgeons score: 58.4 ± 6.2 preoperatively, 85.2 ± 6.4 at the final, P < .001; Rowe score: 49.0 ± 12.2 preoperatively, 86.8 ± 9.1 at the final, P < .001) and postoperative recurrence was occurred in 1patient (2%). No differences were found in clinical outcomes and recurrence rate (4% vs 0%) according to patient positioning, despite the larger number of suture anchors used in group II (6.2 ± 1.5 in group I, 7.6 ± 1.1 in group II, P < .001). CONCLUSIONS It remained difficult to preoperatively diagnose panlabral tear using standard physical examinations and imaging studies. Nevertheless, arthroscopic stabilization procedures for patients with panlabral tear provided satisfactory clinical outcomes with a low recurrence rate. Patient position during surgery did not alter clinical outcomes and recurrence rate, despite the use of different numbers of suture anchors.

Abstract
Combined tears of the anterior, posterior, and superior glenoid labrum have not been commonly reported in the literature. These lesions represent a small, but significant portion of labral injuries. Care should be taken in the diagnosis and management of these lesions because preoperative physical examination and imaging may have limited ability to detect the full extent of pathology. Arthroscopic repair of panlabral tears produces good to excellent outcomes and a low rate of recurrent instability at short-term follow-up, both when performed in the beach chair position and in the lateral decubitus position. Surgical positioning, therefore, should be based on surgeon preference.

Abstract
Shoulder instability is common in athletes. Combined labral injuries are also common and appear more frequently in chronic cases, suggesting propagation of smaller tears with each event. Panlabral tears, or 270 tears, represent an extreme form of this phenomenon. Arthroscopy has allowed for improved appreciation of these combined patterns. Although it is essential to fix all labral lesions identified during arthroscopy, it is also crucial to enter surgical cases with a clear diagnosis (i.e., anterior, posterior, or combined instability) to adequately address symptoms.

Abstract
PURPOSE To review the current literature available and evaluate the efficacy of arthroscopic repair of 270° and 360° labral tears, as well as the complication rates associated with such. In addition, we intend to investigate whether consistent clinical findings can be observed in these patients. METHODS This review is registered in the PROSPERO database. The MEDLINE, Cochrane Library, Scopus, and EMBASE databases were queried, and additional searches were performed manually. Studies that reported outcomes after arthroscopic repair of a minimum of 270° of glenoid labrum were included. Technique articles, repairs of less than 270°, studies on atraumatic multidirectional instability, and studies that lacked observable outcomes were excluded. RESULTS In total, 3031 studies/documents were identified from database and manual searching. Screening, removal of duplicates, and assessment for inclusion/exclusion criteria resulted in 6 level IV studies for review. History and physical examination, as well as advanced imaging findings, were variable across studies. All studies reported satisfactory outcomes at short- to mid-term follow-up, although there was heterogeneity in type of outcomes used. Return to sport ranged from 75% to 100%. Complication rates ranged from 10% to 30%. Notably, recurrence of instability and need for secondary surgery occurred in up to 15% of patients. CONCLUSIONS The current literature suggests that although clinical and radiographic variability exist in the diagnosis of 270° and 360° glenoid labrum tears, successful outcomes and return to work/sport can be achieved with arthroscopic management at an average minimum follow-up of 1 year. These figures, however, are limited by heterogenous studies containing small numbers of patients. Complications occur in up to 30% of cases, including an instability recurrence rate of up to 15%.

Abstract
Background: Circumferential tears of the glenohumeral labrum are an uncommon injury, comprising 2.4% of all labral lesions. Currently, the clinical outcomes of arthroscopic circumferential labral repair for patients with instability and combined anterior, posterior, and superior labral tears are not well-known. Hypothesis: Patients treated with arthroscopic circumferential shoulder labral repairs will have inferior clinical outcomes and higher failure rates compared with patients who have isolated arthroscopic anterior labral repairs. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective cohort study was performed to identify patients aged 18 years and older who underwent circumferential arthroscopic stabilization for recurrent instability as compared with an age-matched control group of arthroscopic primary anterior labral repairs. Age at surgery, American Shoulder and Elbow Surgeons (ASES) Standardized Shoulder Assessment Form score, Simple Shoulder Test (SST) score, 12-Item Short Form Health Survey (SF-12) score (mental and physical), and overall patient satisfaction with surgery were assessed for each group. Results: A total of 35 consecutive patients (36 shoulders) who underwent an arthroscopic 360° circumferential labral repair were compared with a matched group of 31 patients who underwent an isolated arthroscopic anterior labral repair. The mean follow-up period was 34.3 and 56.8 months, respectively. No significant difference was found between the 2 groups for overall satisfaction with the surgery or recurrent instability. At the time of the follow-up survey, 22% of the patients experienced pain and 25% of the patients experienced instability in the circumferential repair group, whereas 15% of the patients experienced some level of pain and 30% of patients experienced a subjective sense of subtle instability in the isolated repair group. The ASES scores were 87.3 in the combined labral repair group and 93.3 in the isolated anterior group (P = .35), SST scores were 10.7 and 11.3 (P = .70), SF-12 mental scores were 54.6 and 56.8 (P = .80), SF-12 physical scores were 53.2 and 54.2 (P = .98), and age at time of the surgery was 26.7 and 24.6 years (P = .33), respectively. There was no difference between the 2 groups in pre- and postoperative range of motion (P > .05). Conclusion: There was no difference in shoulder stability and function in patients after 360° combined labral repairs versus anterior labral repair alone. With proper patient selection, patients can expect similar outcomes despite the more extensive surgical procedure and complex postoperative rehabilitation protocol for circumferential repairs.

Abstract
BACKGROUND The surgical treatment of recurrent shoulder instability has evolved in recent years to include a variety of soft tissue and bone block procedures, undertaken with either an open or arthroscopic approach. Although the utilization of such techniques has rapidly expanded, the associated risk of complications remains poorly defined. This information is vital for clinical decision making and patient counseling. PURPOSE To quantify the complication rate associated with all types of surgery for anterior glenohumeral joint dislocation. STUDY DESIGN Systematic review. METHODS A systematic search was undertaken of studies reporting complications from anterior shoulder stabilization surgery. Inclusion criteria were studies published in English between 2000 and 2017 with a minimum 2-year follow-up. Methodological quality of the included studies was assessed with the Methodological Index for Non-Randomized Studies criteria. Complication rates for all undesirable events contributing to the patient outcome were extracted and cumulative rates calculated. RESULTS Out of 1942 references, 56 studies were included, totaling 4362 procedures among 4336 patients. Arthroscopic soft tissue repair had a complication rate of 1.6% (n = 2805). When repair was combined with arthroscopic remplissage, the rate was 0.5% (n = 219). Open soft tissue repair had a complication rate of 6.2% (n = 219) and open labral repair with remplissage, a rate of 2.3% (n = 79). An open bone block procedure had a complication rate of 7.2% (n = 573) and an arthroscopic bone block procedure, a rate of 13.6% (n = 163). CONCLUSION This large systematic review demonstrates the overall complication rates (not purely recurrence rates) in modern shoulder stabilization surgery. With the growing interest in bone block stabilization procedures, including those performed arthroscopically, surgeons should be aware of the 10-fold increase in complications for these procedures over soft tissue arthroscopic surgery and counsel their patients accordingly.

Abstract
BACKGROUND A curved-drill guide system was recently introduced to achieve a better trajectory for a low anteroinferior anchor during arthroscopic Bankart repair. However, the clinical performance of such a device remains unclear. The purpose of this study was to evaluate the trajectory and position of the low anteroinferior suture anchor with use of the curved-guide system in clinical cases. METHODS We enrolled 41 cases of arthroscopic Bankart repair in this study. Of these cases, 9 were repaired using the curved drill guide whereas 32 were repaired using a conventional straight guide. Postoperative computed tomography scans were obtained, and 3-dimensional models of the scapula were reconstructed. Notable perforations of the opposite cortex by the most inferior anchors were recorded. The clock-face angle, insertion angle, and insertion distance were measured. RESULTS The anchor perforation rate in the curved-guide group (11%) was significantly lower than that in the straight-guide group (56%) (P = .02). The insertion distance in the curved-guide group was significantly shorter than that in the straight-guide group (4.0 ± 1.6 mm vs. 7.0 ± 2.4 mm, P < .01). The clock-face angle and insertion angle were significantly greater in the perforated straight-guide group than in the nonperforated groups. The percentage of anchors in the absolute safe zone (clock-face angle > 135° and < 165° and insertion angle < 100°), where no anchors perforated, was greater in the curved-guide group than the straight-guide group. CONCLUSION Compared with the conventional straight guide, the curved-guide system provides better placement of the most inferior suture anchor during arthroscopic Bankart repair.

Abstract
Recent literature has suggested that patient positioning matters when it comes to arthroscopic anterior shoulder stabilization. Although advocates of the lateral decubitus position argue that only in this position can the anteroinferior and posteroinferior aspects of the glenoid be adequately visualized and instrumented, outcomes following posterior shoulder stabilization appear independent of patient position.

Abstract
Combined lesions of the glenoid labrum are a relatively common finding in shoulder instability patients. Even so, relatively few studies have been published evaluating outcomes after repair of these complex labral detachments. To achieve a successful outcome, accurate identification of all pathologic lesions in the shoulder combined with an organized, stepwise approach to sometimes circumferential labral fixation is required. Repair of 360° labral tears can be effectively and efficiently achieved by implementing the reproducible steps and sequence described to reconstruct these circumferential labral tears.

Abstract
Glenohumeral instability is one of the more common conditions seen by sports medicine physicians, especially in young, active athletes. The associated anatomy of the glenohumeral joint (the shallow nature of the glenoid and the increased motion it allows) make the shoulder more prone to instability events as compared with other joints. Although traumatic dislocations or instability events associated with acute labral tears (ie, Bankart lesions) are well described in the literature, there exists other special shoulder conditions that are also associated with shoulder instability: superior labrum anterior/posterior (SLAP) tears, pan-labral tears, and multidirectional instability. SLAP tears can be difficult to diagnose and arthroscopic diagnosis remains the gold standard. Surgical treatment as ranged from repair to biceps tenodesis with varying reports of success. Along the spectrum of SLAP tears, pan-labral tears consist of 360-degree injuries to the labrum. Patients can present complaining of either anterior or posterior instability alone, making the physical examination and advanced imaging a crucial component of the work up of the patients. Arthroscopic labral repair remains a good initial option for surgical treatment of these conditions. Multidirectional instability remains one of the more difficult conditions for the sports medicine physician to diagnose and treat. Symptoms may only be reported as vague pain versus frank instability making the diagnoses particularly challenging, especially in a patient with overall joint laxity. Conservative management to include physical therapy is the mainstay initial treatment in patients without an identifiable structural abnormality. Surgical management of this condition has evolved from open to arthroscopic capsular shifts with comparable results.

Abstract
Injuries to the glenoid labrum can result in shoulder instability and pain. These lesions may occur anywhere around the glenoid labrum, and thus, the arthroscopist must be prepared to approach all aspects of the glenoid from multiple angles. The pan-labral or circumferential (360°) tear of the glenoid labrum presents a unique challenge to even the experienced arthroscopist. The extent of the lesion requires the use of accessory portals and percutaneous techniques to establish adequate visualization and to facilitate the proper trajectory for anchor placement. The pan-labral tear also demands intraoperative planning throughout the repair to ensure proper tensioning and alignment of the labrum and capsular tissue. The purposes of this article are to report a technique for repairing a pan-labral lesion and to emphasize the use of accessory portals and percutaneous techniques for complete access to the glenoid.

Abstract
Post-instability arthropathy may commonly develop in high-risk patients with a history of recurrent glenohumeral instability, both with and without surgical stabilization. Classically related to anterior shoulder instability, the incidence and rates of arthritic progression may vary widely. Radiographic arthritic changes may be present in up to two-thirds of patients after primary Bankart repair and 30% after Latarjet procedure, with increasing rates associated with recurrent dislocation history, prominent implant position, non-anatomic reconstruction, and/or lateralized bone graft placement. However, the presence radiographic arthrosis does not predict poor patient-reported function. After exhausting conservative measures, both joint-preserving and arthroplasty surgical options may be considered depending on a combination of patient-specific and anatomic factors. Arthroscopic procedures are optimally indicated for individuals with focal disease and may yield superior symptomatic relief when combined with treatment of combined shoulder pathology. For more advanced secondary arthropathy, total shoulder arthroplasty remains the most reliable option, although the clinical outcomes, wear characteristics, and implant survivorship remains a concern among active, young patients.

Abstract
OBJECTIVE To evaluate the clinical results among patients undergoing arthroscopic repair of circumferential labral lesions. METHODS This was a retrospective study on 10 patients who underwent arthroscopic repair to circumferential labral lesions of the shoulder, between September 2012 and September 2015. The patients were evaluated by means of the Carter-Rowe score, DASH score, UCLA score, visual analog scale (VAS) for pain and Short-Form 36 (SF36). The average age at surgery was 29.6 years. The mean follow-up was 27.44 months (range: 12-41.3). RESULTS The mean score was 16 points for DASH; 32 points for UCLA, among which six patients (60%) had excellent results, three (30%) good and one (10%) poor; 1.8 points for VAS, among which nine patients (90%) had minor pain and one (10%) moderate pain; 79.47 for SF-36; and 92.5 for Carter-Rowe, among which nine patients (90%) had excellent results and one (10%) good. Joint degeneration was present in one case (10%), of grade 1. We did not observe any significant complications, except for grade 1 glenohumeral arthrosis, which one patient developed after the operation. CONCLUSION Arthroscopic repair of circumferential labral lesions of the shoulder through use of absorbable anchors is effective, with improvements in all scores applied, and it presents low complication rates. Cases associated with glenohumeral dislocation have lower long-term residual pain.

Abstract
CONTEXT Given its young, predominately male demographics and intense physical demands, the US military remains an ideal cohort for the study of anterior shoulder instability. EVIDENCE ACQUISITION A literature search of PubMed, MEDLINE, and the Cochrane Database was performed to identify all peer-reviewed publications from 1950 to 2016 from US military orthopaedic surgeons focusing on the management of anterior shoulder instability. STUDY DESIGN Clinical review. LEVEL OF EVIDENCE Level 4. RESULTS The incidence of anterior shoulder instability events in the military occurs at an order of magnitude greater than in civilian populations, with rates as high as 3% per year among high-risk groups. With more than 90% risk of a Bankart lesion and high risk for instability recurrence, the military has advocated for early intervention of first-time shoulder instability while documenting up to 76% relative risk reduction versus nonoperative treatment. Preoperative evaluation with advanced radiographic imaging should be used to evaluate for attritional bone loss or "off-track" engaging defects to guide comprehensive surgical management. With complex recurrent shoulder instability and/or cases of clinically significant osseous lesions, potential options such as remplissage, anterior open capsular procedures, or bone augmentation procedures may be preferentially considered. CONCLUSION Careful risk stratification, clinical evaluation, and selective surgical management for at-risk military patients with anterior shoulder instability can optimize the recurrence risk and functional outcome in this population.

Abstract
Purpose: The 2-year outcomes of patients undergoing repair of triple labrum tears using an all-suture anchor device were assessed. Materials and Methods: Eighteen patients (17 male, one female; mean age 36.4 years, range: 14.2-62.3 years) with triple labrum tears underwent arthroscopic repair using the 1.4 mm JuggerKnot Soft Anchor (mean number of anchors 11.5, range: 9-19 anchors). Five patients had prior surgeries performed on their operative shoulder. Patients were followed for a mean of 2.0 years (range: 1.6-3.0 years). Constant–Murley shoulder score (CS) and Flexilevel scale of shoulder function (FLEX-SF) scores were measured, with preoperative and final postoperative mean scores compared with a paired Student's t-test (P < 0.05). Magnetic resonance imaging (MRI) was also performed at final postoperative. Results: Overall total CS and FLEX-SF scores increased from 52.9 ± 20.4 to 84.3 ± 10.7 (P < 0.0001) and from 29.3 ± 4.7 to 42.0 ± 7.3 (P < 0.0001), respectively. When divided into two groups by whether or not glenohumeral arthrosis was present at the time of surgery (n = 9 each group), significant improvements in CS and FLEX-SF were obtained for both groups (P < 0.0015). There were no intraoperative complications. All patients, including contact athletes, returned to their preinjury level of sports activity and were satisfied. MRI evaluation revealed no instances of subchondral cyst formation or tunnel expansion. Anchor tracts appeared to heal with fibrous tissue, complete bony healing, or combined fibro-osseous healing. Conclusion: Our results are encouraging, demonstrating a consistent healing of the anchor tunnels through arthroscopic treatment of complex labrum lesions with a completely suture-based implant. It further demonstrates a meaningful improvement in patient outcomes, a predictable return to activity, and a high rate of patient satisfaction. Level of Evidence: Level IV case series.

Abstract
OBJECTIVE The purpose of this study was to describe the epidemiology and demographics of surgically treated shoulder instability stratified by direction. We hypothesized that there would be an increased frequency of posterior and combined shoulder instability in our population compared with published literature. Secondarily, we assessed preoperative magnetic resonance imaging (MRI) reports to determine how accurately they detected the pathology addressed at surgery. MATERIALS AND METHODS A retrospective review was conducted at a single facility during a 46-month period. The study included all patients who underwent an operative intervention for shoulder instability. The instability in each case was characterized as isolated anterior, isolated posterior, or combined, according to pathologic findings confirmed at arthroscopy. The findings were retrospectively compared with official MRI reports to determine the accuracy of MRI in characterizing the clinically and operatively confirmed diagnosis. RESULTS A consecutive series of 231 patients (221 men, 10 women) underwent stabilization for shoulder instability over 46 months. Patients were a mean age of 26.0 years. There were 132 patients (57.1%) with isolated anterior instability, 56 (24.2%) with isolated posterior instability, and 43 (18.6%) with combined instability. Overall, MRI findings completely characterized the clinical diagnosis and arthroscopic pathology in 149 of 219 patients (68.0%). CONCLUSION The rate of posterior and combined instability in an active population is more common than has been previously reported, making up more than 40% of operatively treated instability, including a previously unreported incidence of 19% for combined instabilities. In addition, MRI was often incomplete or inaccurate in detecting the pathology eventually treated at surgery.

Abstract
Recurrent anterior instability is a common finding after traumatic glenohumeral dislocation in the young, athletic patient population. A variety of concomitant pathologies may be present in addition to the classic Bankart lesion, including glenoid bone loss; humeral head bone loss; rotator interval pathology; complex/large capsular injuries including humeral avulsions of the glenohumeral ligaments (HAGL lesions), SLAP tears, near circumferential labral tears, and anterior labral periosteal sleeve avulsions (ALPSA lesions); and rotator cuff tears. Normal anatomic variations masquerading as pathology also may be present. Recognition and treatment of these associated pathologies are necessary to improve function and symptoms of pain and to confer anterior shoulder stability. This review will focus on the history, physical examination findings, imaging findings, and recommended treatment options for common sources of copathology in anterior shoulder instability repair.

Abstract
PURPOSE This study aimed to systematically review the clinical outcomes and recurrence rates after arthroscopic anterior shoulder stabilization in the beach chair (BC) and lateral decubitus (LD) positions. METHODS The authors performed a systematic review of multiple medical databases using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. All English-language literature from 1990 to 2013 reporting clinical outcomes after arthroscopic anterior shoulder stabilization with suture anchors or tacks with a minimum 2-year follow-up period were reviewed by 2 independent reviewers. Data on recurrent instability rate, return to activity/sport, range of motion, and subjective outcome measures were collected. Study methodological quality was evaluated with the Modified Coleman Methodology Score (MCMS) and the Quality Appraisal Tool (QAT). To quantify the structured review of observational data, meta-analytic statistical methods were used. RESULTS Sixty-four studies (38 BC position, 26 LD position) met inclusion criteria. A total of 3,668 shoulders were included, with 2,211 of patients in the BC position (average age, 26.7 ± 3.8 years; 84.5% male sex) and 1,457 patients in the LD position (average age, 26.0 ± 3.0 years; 82.7% male sex). The average follow-up was 49.8 ± 29.5 months in the BC group compared with 38.7 ± 23.3 months in the LD group. Average overall recurrent instability rates were 14.65 ± 8.4% in the BC group (range, 0% to 38%) compared with 8.5% ± 7.1% in the LD group (range, 0% to 30%; P = .002). The average postoperative loss in external rotation motion (in abduction) was reported in 19 studies in the BC group and in13 studies in the LD group, with an average loss of 2.4° ± 1.0° and 3.6° ± 2.6° in each group, respectively (P > .05). CONCLUSIONS Excellent clinical outcomes with low recurrence rates can be obtained after arthroscopic anterior shoulder stabilization in either the BC or the LD position; however, lower recurrence rates are noted in the LD position. Additional long-term randomized clinical trials comparing these positions are needed to better understand the potential advantages and disadvantages of each position. LEVEL OF EVIDENCE Level IV, systematic review of studies with Level I through Level IV evidence.

Inferior suture anchor placement during arthroscopic Bankart repair: influence of portal placement and curved drill guide. Am J Sports Med 2014; 42:1182-9.

Abstract
BACKGROUND During arthroscopic Bankart repair, inferior anchor placement is critical to a successful outcome. Low anterior anchors may be placed with a standard straight guide via midglenoid portal, with a straight guide with trans-subscapularis placement, or with curved guide systems. Purpose/ HYPOTHESIS To evaluate glenoid suture anchor trajectory, position, and biomechanical performance as a function of portal location and insertion technique. It is hypothesized that a trans-subscapularis portal or curved guide will improve anchor position, decrease risk of opposite cortex breach, and confer improved biomechanical properties. STUDY DESIGN Controlled laboratory study. METHODS Thirty cadaveric shoulders were randomized to 1 of 3 groups: straight guide, midglenoid portal (MG); straight guide, trans-subscapularis portal (TS); and curved guide, midglenoid portal (CG). Three BioRaptor PK 2.3-mm anchors were inserted arthroscopically, with an anchor placed at 3, 5, and 7 o'clock. Specimens were dissected with any anchor perforation of the opposite cortex noted. An "en face" image was used to evaluate actual anchor position on a clockface scale. Each suture anchor underwent cyclic loading (10-60 N, 250 cycles), followed by a load-to-failure test (12.5 mm/s). Fisher exact test and mixed effects regression modeling were used to compare outcomes among groups. RESULTS Anchor placement deviated from the desired position by 9.9° ± 11.4° in MG specimens, 11.1° ± 13.8° in TS, and 13.1° ± 14.5° in CG. After dissection, opposite cortex perforation at 5 o'clock occurred in 50% of MG anchors, 0% of TS, and 40% of CG. Of the 90 anchors tested, 17 (19%) failed during cyclic loading, with a similar failure rate across groups (P = .816). The maximum load was significantly higher for the 3-o'clock anchors when compared with the 5-o'clock anchors, regardless of portal or guide (P = .021). For the 5-o'clock position, there were significantly fewer "out" anchors in the TS group versus the CG or MG group (P = .038). There was no statistically significant difference in maximum load among groups at 5 o'clock. CONCLUSION Accuracy in suture anchor placement during arthroscopic Bankart repair can vary depending on both portal used and desired position of anchor. The results of the current study indicate that there was no difference in ultimate load to failure among anchors inserted via a midglenoid straight guide, midglenoid curved guide, or percutaneous trans-subscapularis approach. However, midglenoid portal anchors drilled with a straight or curved guide and placed at the 5-o'clock position had significant increased risk of opposite cortex perforation compared with trans-subscapularis percutaneous insertion, with no apparent biomechanical detriment. CLINICAL RELEVANCE The findings from this study will facilitate improved understanding of risks and benefits of several techniques for arthroscopic shoulder instability treatment with regard to suture anchor fixation.

Abstract
BACKGROUND With the continuous development of arthroscopic techniques, the majority of superior labrum anterior-posterior (SLAP) lesions can be treated with minimally invasive endoscopic repair. The aim of this study was to determine the efficacy of arthroscopic capsulolabral reconstruction of SLAP lesions with extensive tears. METHODS Eighteen patients with SLAP lesions with extensive tears (median age, 27.50 years) were included in this study. Twelve patients had type-V SLAP lesions, 4 patients had type-VIII SLAP lesions, and 2 patients had deeply located SLAP lesions. The average duration of follow-up was 15.83 months (range, 11-22 months). Outcome measures included shoulder range of motion (ROM), American Shoulder and Elbow Surgeons (ASES) and Constant-Murley scores, and visual analogue scale (VAS) pain score. RESULTS After arthroscopic surgery, shoulder forward flexion, shoulder external rotation, and external rotation in 90° of abduction were significantly greater than before surgery (169.5° vs. 165.5°, P = 0.001), (90° vs. 63.5°, P < 0.001), and (90° vs. 81.5°, P = 0.004), respectively. Median ASES and Constant-Murley scores after surgery were both 94 as compared to 77.0 and 77.5, respectively, before surgery (both, P < 0.001). The median VAS score decreased to 1.5 after surgery as compared to 6 before surgery (P < 0.001). CONCLUSIONS Arthroscopic repair of SLAP lesions with extensive tears can achieve good outcomes.

Abstract
PURPOSE The purpose of this study was to evaluate the sensitivity of preoperative magnetic resonance imaging (MRI) in detecting combined lesions of the glenoid labrum involving tears of the anterior, posterior, and superior labrum. METHODS Preoperative MRI findings were available in 46 cases of arthroscopic repair of combined tears of the anterior, posterior, and superior labrum (mean age, 31 years), including 23 noncontrast MRI studies and 24 magnetic resonance (MR) arthrography studies (1 patient had both). MRI findings were compared with the status of the labrum at the time of arthroscopy, and the sensitivity of MRI was determined. RESULTS MRI showed evidence of combined lesions of the anterior, posterior, and superior labrum in only 10 of 47 studies (21.3%). Only 2 of 23 (8.7%) tears were detected by noncontrast MRI, compared with 8 of 24 (33.3%) by MR arthrography (P = .07). Non-contrast MRI showed evidence of labral pathology in more than one direction in 10 of 23 studies (43.5%), compared with 20 of 24 MR arthrography studies (83.3%) (P = .006). Noncontrast MRI showed no evidence of a labral tear in 3 of 23 patients (13.0%), whereas no MR arthrogram was completely negative for a labral tear (0%) (P = .11). CONCLUSIONS Combined tears of the anterior, posterior, and superior glenoid labrum are infrequent injuries that are typically not completely defined by either noncontrast MRI or MR arthrography. LEVEL OF EVIDENCE Level III, diagnostic study.

Abstract
BACKGROUND Combined lesions of the glenoid labrum involving tears of the anterior, posterior, and superior labrum have been infrequently reported in the literature. PURPOSE To evaluate the clinical outcomes of arthroscopic repair of these lesions in a general population using validated scoring instruments, presence of complications, and need for revision surgery. STUDY DESIGN Case series; Level of evidence, 4. METHODS Fifty-eight patients who had arthroscopic labral repair of tears involving the anterior, posterior, and superior labrum (defined as a panlabral repair) were identified at our institution by retrospective review. All patients underwent arthroscopic labral repair with suture anchor fixation by a uniform approach and with a standardized postoperative protocol. Forty-four patients had a minimum 16-month postoperative follow-up. Outcomes were assessed postoperatively by the American Shoulder and Elbow Surgeons (ASES) score and the Penn Shoulder score. Complications were also documented, including need for revision surgery. RESULTS The mean age at the time of surgery was 32 years (range, 15-55 years) in the 44 patients. Presenting shoulder complaints included pain alone (40%), instability alone (14%), or pain and instability (45%). Mean number of anchors per repair was 7.9 (range, 5-12). Mean follow-up was 42 months (range, 16-78 months). Mean ± standard deviation ASES score at final follow-up was 90.1 ± 17.7 (range, 22-100), and mean Penn Shoulder score was 90.2 ± 15.3 (range, 38-100). Three of the 4 patients with outcome scores of 70 or less at final follow-up had undergone prior surgery. Thirteen postoperative complications (30%) occurred, with 3 (7%) requiring a second surgery. Five patients (11%) had an instability event following panlabral repair, but only 1 of these patients (2%) required revision surgery for a recurrent labral tear. CONCLUSION Combined tears of the anterior, posterior, and superior glenoid labrum represent a small but significant portion of labral injuries. Arthroscopic repair of these injuries can be performed with good postoperative outcomes and a low rate of recurrent labral injury.

Abstract
Advances in shoulder arthroscopy and improved understanding of the pathoanatomy following shoulder instability have led to increased recognition of combined lesions of the glenoid labrum. Although the diagnosis of combined labral tears is often made with physical examination and magnetic resonance imaging, combined tears can be discovered intraoperatively. A high index of suspicion is necessary, especially in the setting of chronic recurrent shoulder instability or previous failed labral repair. Over a 6-year period at a military institution, combined labral repairs comprised 37% of all patients undergoing any labral repair. With accurate identification of all labral pathology and a systematic approach to labral repair, successful outcomes can be achieved.

Abstract
BACKGROUND Traumatic labral tears involving the anterior, inferior, and posterior aspects of the glenoid fossa represent a unique subpopulation of shoulder instability. PURPOSE This study was undertaken to evaluate prospectively the clinical results of patients who underwent arthroscopic repair of 270° labral tears. STUDY DESIGN Case series; Level of evidence, 4. METHODS This was a prospective outcomes analysis of patients who underwent arthroscopic stabilization of a 270° labral tear. Inclusion criteria included patients with traumatic injury and primarily anteroinferior instability but several had posterior instability as well. Imaging revealed extensive labral injury in all patients. Indications for repair included symptomatic instability, 2+ anterior-inferior and posterior-inferior load-shift testing, and arthroscopic confirmation of labral lesions that extended anteriorly, inferiorly, and with extension to the midglenoid posteriorly. Exclusion criteria were SLAP (superior labrum anterior and posterior) lesions, revisions, and nontraumatic injuries. All patients underwent an arthroscopic repair utilizing modern suture anchor technique. Outcome measures included preoperative and postoperative Rowe, American Shoulder and Elbow Surgeons (ASES), Simple Shoulder Test (SST), and Constant Murley scores. The Western Ontario Shoulder Instability Index (WOSI) and the Single Assessment Numeric Evaluation (SANE) scores were collected postoperatively. Failure was defined as any days missed from sport activity or work due to an instability event. RESULTS Twenty-three 270° labral repairs were performed in 21 patients by a single surgeon. Twenty shoulders in 19 patients (92%) were followed for a mean of 28 months (range, 14-47 months) postoperatively. The mean preoperative and postoperative outcome scores showed statistically significant improvements (P ≤ .001): Rowe (59 to 92), ASES (76 to 93), SST (9 to 11), and Constant scores (73 to 95). The mean SANE score was 91 of 100 and the mean WOSI score was 302. Three of the 20 shoulders (in 19 patients) had subsequent episodes of instability for a failure rate of 15%. One required a second procedure for continued instability for a revision rate of 5%. Two patients developed adhesive capsulitis postoperatively of which one required an arthroscopic arthrolysis. CONCLUSION Arthroscopic repair of these extensive labral injuries involving 270° of the glenoid fossa was an effective surgical treatment and restored mechanical stability of the shoulder. The arthroscopic approach allowed for complete visualization and repair of all labral pathology.

Abstract
BACKGROUND Symptomatic pan-labral or circumferential (360°) tears of the glenohumeral labrum are an uncommon injury. The purpose of the present study was to report the results of surgical treatment of circumferential lesions of the glenoid labrum with use of validated outcome instruments. METHODS From July 2003 to May 2006, forty-one shoulders in thirty-nine patients (thirty-four men and five women) with a mean age of 25.1 years were prospectively enrolled in a multicenter study and were managed for a circumferential (360°) lesion of the glenoid labrum. All patients had a primary diagnosis of pain and recurrent shoulder instability, and all underwent arthroscopic repair of the circumferential labral tear with a mean of 7.1 suture anchors. The outcomes for thirty-nine of the forty-one shoulders were assessed after a mean duration of follow-up of 31.8 months on the basis of the rating of pain and instability on a scale of 0 to 10, a physical examination, and three outcome instruments (the Single Assessment Numeric Evaluation score, the modified American Shoulder and Elbow Surgeons score, and the Short Form-12 score). RESULTS Significant improvement was noted in terms of the mean pain score (from 4.3 to 1.1), the mean instability score (from 7.3 to 0.2), the mean modified American Shoulder and Elbow Surgeons score (from 55.5 to 89.6), the mean Short Form-12 score (from 75.7 to 90.0), and the mean Single Assessment Numeric Evaluation score (from 36.7 to 88.5). Six shoulders required revision surgery because of recurrent instability (two), recalcitrant biceps tendinitis (two), or postoperative tightness (two). All patients returned to their preinjury activity level. CONCLUSIONS Pan-labral or circumferential lesions are an uncommon yet extensive injury of the glenohumeral joint that may result in recurrent instability and pain. The present study demonstrates that arthroscopic capsulolabral repair with suture anchor fixation can restore the stability of the glenohumeral joint and can provide a reliable improvement in subjective and objective outcome measures.
