Biceps Tenodesis for the Treatment of Type II Superior Labral Anterior Posterior (SLAP) Tears in Overhead Athletes Under the Age of 35: A Case Series.

The best treatment for type II superior labral anterior posterior (SLAP) tears in overhead athletes is not well defined. The purpose of this study was to examine post-surgical outcomes in overhead athletes under the age of 35 who underwent primary biceps tenodesis for an isolated type II SLAP tear.We hypothesized that these patients would have high rates of return to play, as well as recovery of range of motion (ROM) and strength after surgery. Patients were between the ages of 18 and 35, had a primary isolated type II SLAP tear confirmed on magnetic resonance imaging (MRI), and were injured performing overhead activities.All patients underwent biceps tenodesis using an arthroscopic suprapectoral approach.Patients underwent standard postoperative rehabilitation lasting up to one year.Function and outcomes were measured at baseline, three months, six months, one year, and two years using range of motion, strength testing, and patient-reported outcomes (PROs) (Western Ontario Shoulder Instability Index (WOSI), Kerlan-Jobe Orthopedic Clinic Score (KJOC), American Shoulder and Elbow Surgeons Assessment Form (ASES), and Single Assessment Numeric Evaluation (SANE)). Five patients were included in the case series.There was consistent improvement at each time point on PROs: WOSI, p=0.01; KJOC, p=0.04; SANE, p=0.02; and ASES, p=0.03.Range of motion increased from baseline to each time point with a significant improvement in forward flexion (p=0.03).In strength testing, there were improvements in all exercises and a significant improvement in abducted external rotation between years 1 and 2 (p<0.01). This study demonstrated that biceps tenodesis in overhead athletes under the age of 35 provides improved outcomes, ROM, and strength.

Location of Shoulder Glenoid Labral Tears: A Study of 1763 Consecutive Patients

Background: Anterior shoulder labral tearing has historically been considered the most common location of shoulder labral pathology. Recently, smaller studies have reported that posterior labral involvement may be more common than previously recognized. Purpose: To examine the location of surgically repaired labral tears by a single surgeon over a consecutive 23-year period. Study Design: Case series; Level of evidence, 4. Methods: A total of 1763 consecutive patients who underwent arthroscopic or open shoulder labral repair by a single seniorsports medicine fellowship–trained orthopaedic surgeon between April 2000 and April 2023 were retrospectively reviewed. Current Procedural Terminology codes were used to identify patients, which included 29806, 29807, 29822, and 29823. Exclusion criteria included isolated shoulder manipulation or glenohumeral joint or labral debridement that did not include repair. Intraoperative glenoid labral tears observed were categorized into 7 broad categories: (1) anterior labral tears, (2) posterior labral tears, (3) superior labral anterior posterior (SLAP) type II tears (A, B, or C), (4) SLAP type V tears, (5) SLAP type VIII tears, or (6) circumferential labral tears (combined SLAP, anterior, and posterior labral tear). Shoulders diagnosed with multiple tear patterns (ie, anterior and posterior) were also noted. Results: During the 23-year period, 1763 patients underwent arthroscopic or open labral repair; they included 1295 male and 468 female patients, ranging in age from 12 to 70 years, with a mean age of 23.2 years and median age of 19 years. Overall, 28.4% of tears involved the anterior labrum, 64.9% involved the posterior labrum, and 59.6% involved the superior labrum. Regarding isolated tears, 9.3% were isolated anterior labral tears, 19.7% were isolated posterior labral tears, 11.5% involved the anterior and posterior labrum, 22.2% were isolated superior (SLAP type II-IV) tears, 3.63% were isolated SLAP type V tears, 29.8% were isolated SLAP type VIII tears, and 4.1% were circumferential tears. Conclusion: Posterior shoulder labral tearing was more common than anterior tearing in a large consecutive series of 1763 patients who underwent surgical repair. This highlights the importance of posterior labral pathology, which sometimes may be overlooked because of more vague complaints, with pain and loss of function being the most common.

Current Evidence Based Recommendations on Rehabilitation following Arthroscopic Shoulder Surgery: Rotator Cuff, Instability, Superior Labral Pathology, and Adhesive Capsulitis.

Arthroscopy has become increasingly popular for a addressing a wide variety of shoulder pathology. However, despite increasing interest, there is still much uncertainty and variability amongst providers regarding optimal post-operative rehabilitation. This review provides an overview of the evidence underlying common rehab protocols used following arthroscopic interventions for rotator cuff disease, shoulder instability, superior labral anterior to posterior (SLAP) tears and adhesive capsulitis. For small and medium sized rotator cuff tears, early motion protocols do not seem to affect healing or retear rates, however there is no difference with regards to long term functional outcomes when compared to standard motion protocols. For larger tears (> 3cm), early active motion may be associated with impaired tendon integrity. Early range of motion following arthroscopic Bankart repair has not been shown to increase rate of recurrence, however the data on return to sport requires more granularity to effectively guide care. Further research needs to be done to compare rehab protocols following SLAP repair and arthroscopic capsular release. Rehabilitation protocols following rotator cuff surgery and anterior shoulder stabilization have garnered the most research interest. However, there is still a need for larger higher-level studies examining the long-term effects of different rehab protocols. Regarding the arthroscopic management of other types of shoulder instability, SLAP tears and adhesive capsulitis, there is paucity of high-quality evidence. This knowledge gap likely underpins the variability in different rehab protocols seen in clinical practice, highlighting the need for more research.

Acromioclavicular joint dislocation and concomitant labral lesions: a systematic review.

Acromioclavicular (AC) joint dislocations frequently co-occur with intra-articular glenohumeral pathologies. Few comprehensive studies have focused on labral tears specifically associated with AC joint trauma. This systematic review will address this gap. A comprehensive electronic search was conducted across PubMed, Cochrane Library, and Google Scholar (pages 1-20) spanning from 1976 to May 19, 2023. Seven studies met the inclusion criteria for this systematic review, consisting of three retrospective studies and four case series. These studies collectively involved 1,044 patients, of whom 282 had concomitant labral lesions. The pooled prevalence of intra-articular labral injuries associated with acute AC joint dislocation was 27%. The prevalence of these labral lesions varied significantly between studies, ranging from 13.9% to 84.0% of patients, depending on the study and the grade of AC joint dislocation. Various types of labral tears were reported, with superior labrum anterior to posterior (SLAP) lesions being the most common. The prevalence of SLAP lesions ranged from 7.2% to 77.4%, with higher grades of AC joint dislocations often associated with a higher prevalence of SLAP tears. Moreover, grade V dislocations exhibited a complete correlation with SLAP tears. The studies yielded contradictory findings regarding older age and higher grades of AC joint dislocation as risk factors for concurrent labral lesions. This review underscores the frequent association between labral lesions and AC joint dislocations, particularly in cases of lower-grade injuries. Notably, SLAP lesions emerged as the predominant type of labral tear.

Posterior Compression Test: a Provocative Test for Detecting Posterior Labral Tears.

The purpose is to assess the diagnostic accuracy of a provocative test coined as the 'posterior compression test' (PCT) in those with the suspected posterior labral tear or lesion. A total of 515 'arthroscopic labral repairs' were identified between April 2013 and September 2020. Excluding those with concomitant shoulder pathologies, and only including those with pre-operative documentation of the PCT and/or the Jerk test, 191 patients were included. For the purposes of the analyses, the patients were divided into 'non-posterior' labral tear group which included the anterior labral tears and/or the superior labral anterior-to-posterior (SLAP) tears, versus 'any posterior' labral tear group which included the isolated posterior labral tears, the SLAP tears with posterior extension and the pan-labral tears. When the PCT was performed for the isolated posterior labral tears, the sensitivity was 92.6% with the specificity of 86.5%. The positive predictive value and negative predictive value were 71.4-97%, respectively. The Jerk test's sensitivity was 77.8% but when the two tests were combined, the sensitivity increased up to 96.3%. The combined sensitivity with the Jerk test was still up to 94.6% with the AUC (area under curve) /ROC (receiver operator characteristic) at 0.855. Low 'false-positive' rate with the PCT was observed when the test was performed for the 'non-posterior' labral group, with the sensitivity of 13.5%. The posterior compression test correlated well with the arthroscopic diagnoses in a subset of patients with suspected posterior labral pathology, possibly by means of direct stimulation.

Concomitant Biceps Tenodesis Does Not Portend Inferior Outcomes After Anterior Glenohumeral Stabilization

Background: Military patients are known to suffer disproportionately high rates of glenohumeral instability as well as superior labrum anterior to posterior (SLAP) tears. Additionally, a concomitant SLAP tear is frequently observed in patients with anterior shoulder instability. Even though biceps tenodesis has been demonstrated to produce superior outcomes to SLAP repair in military patients with isolated SLAP lesions, no existing studies have reported on outcomes after simultaneous tenodesis and anterior labral repair in patients with co-existing abnormalities. Purpose: To evaluate outcomes after simultaneous arthroscopic-assisted subpectoral biceps tenodesis and anterior labral repair in military patients younger than 40 years. We also sought to compare these outcomes with those after repair of an isolated anterior labral tear. Study Design: Cohort study; Level of evidence, 3. Methods: This study is a retrospective analysis of all military patients younger than 40 years from a single base who underwent arthroscopic anterior glenohumeral stabilization with or without concomitant biceps tenodesis between January 2010 and December 2019. Patients with glenoid bone loss of >13.5% were not eligible for inclusion. Outcome measures including the visual analog scale (VAS) for pain, the Single Assessment Numeric Evaluation (SANE), the American Shoulder and Elbow Surgeons (ASES) shoulder score, the Rowe instability score, and range of motion were administered preoperatively and postoperatively, and scores were compared between groups. Results: A total of 82 patients met inclusion criteria for the study. All patients were active-duty service members at the time of surgery. The mean follow-up was 87.75 ± 27.05 months in the repair + tenodesis group and 94.07 ± 28.72 months in the isolated repair group (P = .3085). Patients who underwent repair + tenodesis had significantly worse preoperative VAS pain (6.85 ± 1.86 vs 5.02 ± 2.07, respectively; P < .001), ASES (51.78 ± 11.89 vs 62.43 ± 12.35, respectively; P = .0002), and Rowe (26.75 ± 7.81 vs 37.26 ± 14.91, respectively; P = .0002) scores than patients who underwent isolated repair. Both groups experienced significant improvements in outcome scores postoperatively (P < .0001 for all), and there were no statistically significant differences in postoperative outcome scores or range of motion between groups. There were no differences in the percentage of patients who achieved the minimal clinically important difference, substantial clinical benefit, and patient acceptable symptom state for the VAS pain, SANE, ASES, and Rowe scores between groups. Overall, 37 of the 40 (92.50%) patients in the repair + tenodesis group and 40 of the 42 (95.24%) patients in the isolated repair group returned to unrestricted active-duty military service (P = .6045). In addition, 38 (95.00%) patients in the repair + tenodesis group and 40 (95.24%) patients in the isolated repair group returned to preinjury levels of sporting activity (P = .9600). There were no significant differences in the number of failures, revision surgical procedures, or patients discharged from the military between groups (P = .9421, P = .9400, and P = .6045, respectively). Conclusion: The findings of this study indicate that simultaneous biceps tenodesis and labral repair was a viable treatment option for the management of concomitant SLAP and anterior labral lesions in young, active military patients younger than 40 years.

Double Trouble: Combined Neurogenic Thoracic Outlet Syndrome and Superior Labrum Anterior Posterior Tear.

Neurogenic thoracic outlet syndrome and superior labrum anterior posterior tears are usually treated in a staged manner due to different post-operative therapy needs. This case describes successful combined surgery with expedited physical therapy.

Qualitative Research in Return to Sport: a Current Review of the Literature.

Return to sport (RTS) is an important metric tied to patient satisfaction after receiving treatment for a sports-related injury. Recently, there has been an explosion of literature on RTS; yet a comprehensive review encompassing multiple injuries does not exist. Furthermore, RTS has historically been defined by quantitative measures that assess strength, function, and pain but little consideration has been given to psychologic factors nor has there been an open-ended forum for athletes to share with health care providers which factors they feel are most influential for RTS. This review also serves to heighten surgeons' awareness of underlying psychologic/psychosocial factors affecting RTS. Qualitative studies which employ open-ended questioning of athletes who have undergone surgical management of superior labral anterior-posterior (SLAP) tears, shoulder instability, ulnar collateral ligament (UCL) rupture, femoral acetabular impingement (FAI), and anterior cruciate ligament (ACL) tear demonstrate that fear of reinjury, lack of social support, and unrealistic expectations are all barriers to RTS. Qualitative studies give health care providers unique insight into the perspectives of their patients so that unmet postoperative needs can be addressed to facilitate RTS. Sports psychologists, coaches, athletic trainers, and physical therapists should create a positive environment to address these needs and provide optimal, holistic care to return athletes to the field safely. Though time consuming, further qualitative research is necessary to understand the unique factors affecting RTS in athletes.

Outcomes After Open Latarjet in Patients With or Without SLAP Lesions.

Up to 20% of shoulders with anterior instability are associated with superior labrum anterior-posterior (SLAP) lesions, and they remain untreated after an open Latarjet procedure. SLAP lesions can be responsible for pain and feelings of instability in high-demand patients. The aim of this study was to compare the early functional outcomes and return to sport rates in athletes after the Latarjet procedure with versus without associated SLAP lesions. It was hypothesized that untreated SLAP lesions would not influence clinical results. Cohort study; Level of evidence, 3. Inclusion criteria were athletes with anterior shoulder instability treated with Latarjet procedure, a minimum follow-up of 1 year, and an available preoperative computed tomography arthrogram. We recorded patient characteristics; type of sport; bone loss; Rowe, Single Assessment Numeric Evaluation (SANE), and 11-item Disabilities of the Arm, Shoulder and Hand (QuickDASH) scores; 5-point pain and satisfaction scores; reported apprehension; and return to sport. Patients with and without a preoperative type 5 SLAP lesion on imaging were compared. Fifty patients were included (mean age, 22 ± 5 years [range, 16-36 years]; mean follow-up, 27 ± 9 months [range, 12-42 months]). Thirty-four patients practiced contact sports, including 20 rugby players. Twelve patients (24%) had a preoperative SLAP lesion. Groups with (+) and without (-) a SLAP lesion were comparable in terms of age, sex, number of instability episodes, type of sport, and glenoid and humeral bone loss. The SLAP+ group had significantly worse outcomes with a lower Rowe score (79 ± 23 vs 91 ± 15; P = .018) and painless rate (50% vs 77%; P = .04). There were no significant differences between the groups in SANE score (SLAP+ vs SLAP-: 80% vs 87%), QuickDASH score (8% vs 8%), return to sport (83% vs 91%), apprehension (79% vs 50%), and reported satisfaction. There was 1 episode of postoperative subluxation in each group. Patients who underwent an open Latarjet procedure with an associated SLAP tear more frequently reported postoperative pain than those without a SLAP lesion. Patients with untreated SLAP tears had significantly lower Rowe scores, although SANE score and return to sport were not significantly different between the groups.

Midterm Outcomes Following Combined Biceps Tenodesis and Anterior Labral Repair in Active Duty Military Patients Younger Than 35 Years

Background: Superior labrum anterior-posterior (SLAP) lesions and anterior instability are common causes of shoulder pain and dysfunction among active-duty members of the United States military. However, little data have been published regarding the surgical management of type V SLAP lesions. Purpose: To compare the outcomes of arthroscopic-assisted subpectoral biceps tenodesis and anterior labral repair with those of arthroscopic SLAP repair (defined as contiguous repair spanning from the superior labrum to the anteroinferior labrum) for type V SLAP tears in active-duty military patients younger than 35 years. Study Design: Cohort study; Level of evidence, 3. Methods: All consecutive patients from January 2010 to December 2015 who underwent arthroscopic SLAP repair or combined biceps tenodesis and anterior labral repair for a type V SLAP lesion with a minimum 5-year follow-up were identified. The decision to perform type V SLAP repair versus combined biceps tenodesis and anterior labral repair was based on the condition of the long head of the biceps tendon (LHBT). Labral repair was performed in patients who had a type V SLAP tear with an otherwise clinically and anatomically healthy LHBT. Combined tenodesis and repair was performed in patients with evidence of LHBT abnormalities. Outcomes including the visual analog scale (VAS) score, the Single Assessment Numeric Evaluation (SANE) score, the American Shoulder and Elbow Surgeons (ASES) shoulder score, the Rowe instability score, and range of motion were collected preoperatively and postoperatively, and scores were compared between the groups. Results: A total of 84 patients met the inclusion criteria for the study. All patients were active-duty service members at the time of surgery. A total of 44 patients underwent arthroscopic type V SLAP repair, and 40 patients underwent anterior labral repair with biceps tenodesis. The mean follow-up was 102.59 ± 20.98 months in the repair group and 94.50 ± 27.11 months in the tenodesis group (P = .1281). There were no significant differences in preoperative range of motion or outcome scores between the groups. Both groups experienced statistically significant improvements in outcome scores postoperatively (P < .0001 for all); however, compared with the repair group, the tenodesis group reported significantly better postoperative VAS (2.52 ± 2.36 vs 1.50 ± 1.91, respectively; P = .0328), SANE (86.82 ± 11.00 vs 93.43 ± 8.81, respectively; P = .0034), and ASES (83.32 ± 15.31 vs 89.90 ± 13.31, respectively; P = .0394) scores. There were no differences in the percentage of patients who achieved the minimal clinically important difference, substantial clinical benefit, and patient acceptable symptom state for the SANE and ASES between the groups. Overall, 34 patients in each group returned to preinjury levels of work (77.3% vs 85.0%, respectively; P = .3677), and 32 patients (72.7%) in the repair group and 33 patients (82.5%) in the tenodesis group returned to preinjury levels of sporting activity (P = .2850). There were no significant differences in the number of failures, revision surgical procedures, or patients discharged from the military between the groups (P = .0923, P = .1602, and P = .2919, respectively). Conclusion: Both arthroscopic-assisted subpectoral biceps tenodesis combined with anterior labral repair and arthroscopic SLAP repair led to statistically and clinically significant increases in outcome scores, marked improvements in pain, and high rates of return to unrestricted active duty in military patients with type V SLAP lesions. The results of this study suggest that biceps tenodesis combined with anterior labral repair produces comparable outcomes to arthroscopic type V SLAP repair in active-duty military patients younger than 35 years.

Return to Sport and Patient-Reported Outcomes After Subpectoral Biceps Tenodesis for SLAP Tear in Collegiate Gymnasts.

The biceps superior labral complex is a known source of shoulder dysfunction in young, high-level athletes. Superior labral anterior-posterior (SLAP) repairs are often unsatisfactory for treating biceps-labral pathology in this demographic group, with high failure rates and poor return to sport (RTS). Minimal data have been published to demonstrate patient-reported outcomes (PROs) and RTS in gymnasts after treatment of SLAP pathologies. Gymnasts undergoing biceps tenodesis for SLAP pathologies would have satisfactory PROs and satisfactory RTS. Case series; Level of evidence, 4. Gymnasts aged ≤25 years who underwent open subpectoral biceps tenodesis for SLAP tears with or without biceps tendon pathology between August 20, 2014, and August 20, 2019, and who had minimum 2-year follow-up data were included in this study. Tenodesis was performed using a subpectoral technique with bicortical button fixation. The following PROs were included: RTS, postoperative activity level, 10-point visual analog scale for pain (VAS-Pain), American Shoulder and Elbow Surgeons (ASES), and Disabilities of the Arm, Shoulder and Hand (DASH) scores. Of 16 shoulders in 14 gymnasts undergoing biceps tenodesis for SLAP tear during the study period, a follow-up was obtained for 13 of 16 shoulders (81%) at 4.3 ± 1.5 years. The mean age of patients at the time of surgery was 21.8 ± 2.2 years, with 12 (92%) male patients. Biceps tenodesis was performed as the primary procedure for the diagnosis of SLAP tear in 12 patients (92%) and for failed prior SLAP repair in 1 patient (8%). PROs were excellent at the follow-up, with VAS-Pain scores of 1.8 ± 1.7, ASES scores of 89.1 ± 9.1, and DASH scores of 2.4 ± 3.2. After surgery, 8 (62%) patients returned to their prior level of collegiate gymnastics. Three (60%) of 5 patients did not return to collegiate gymnastics because of the end of eligibility, and 2 (40%) patients did not return to collegiate gymnastics because of knee injuries. Significantly higher DASH scores were noted in the group that did not RTS (P = .04). No patients experienced postoperative complications or reoperation. Biceps tenodesis was an effective primary operation for high-level gymnasts with SLAP tears, with a satisfactory rate of return to the same level of sport and excellent PROs.

Clinical outcomes and return to play in softball players following SLAP repair or biceps tenodesis.

Shoulder pain due to labral tears and biceps tendonitis is commonly found in softball players. Surgical options include labral repair and biceps tenodesis. Although past studies are limited by heterogeneous study groups from multiple sports, this is the first study that assesses clinical outcomes and return to play rates for fast-pitch softball players. The purpose of this study was to evaluate the clinical outcomes and return to play for fast-pitch softball players treated for a superior labrum anterior posterior (SLAP) tear and recalcitrant biceps tendonitis with a biceps tenodesis compared with a traditional SLAP repair. We hypothesized that the biceps tenodesis would have comparable outcomes with a faster return to play compared with SLAP repair. We performed a retrospective analysis on fast-pitch softball players treated surgically for SLAP tear, recalcitrant biceps tendonitis, or a combination between 2001 and 2019 at our institution. Inclusion criteria were fast-pitch softball players who underwent biceps tenodesis or a SLAP repair with greater than 2-year follow-up. Exclusion criteria involved slow-pitch softball players, patients with less than 2-year follow-up, and patients who had undergone concomitant procedures on the ipsilateral shoulder at the time of SLAP repair or biceps tenodesis. Follow-up was either self-reported through OBERD, a patient-reported outcomes (PRO)-managing software, or achieved over the phone. Follow-up data included American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form score, Andrews Carson Score, Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow Score, Numeric Rating Scale for Pain, and our institution-specific return-to-play questionnaire. We statistically compared players who underwent biceps tenodesis or a SLAP repair, and compared pitchers with position players using Student t tests and Fisher exact test with statistical significance determined to be P<.05. From 60 eligible patients identified, follow-up outcome data were successfully captured for 47 (78%). Of the 18 SLAP repair patients, 17 (94%) returned to full competition at an average of 7.9 months. Of the 29 patients who underwent biceps tenodesis, 27 (93%) returned to full competition at an average of 7.1 months. Statistical analysis of PRO scores for each group found no significant differences between any of the measures used to evaluate patient outcomes, including no statistical difference in pitchers compared with position players. In conclusion, this study demonstrated comparable outcomes between SLAP repairs and biceps tenodesis procedures among our study group of fast-pitch softball players. There was no significant difference between RTP times between the 2 groups.

Poor Psychological Readiness Inhibits Return to Play Following Operative Management of Superior-Labrum Anterior-Posterior Tears

The purposes of this study were to determine why athletes did not return to play (RTP) following operative management of superior-labrum anterior-posterior (SLAP) tears, compare these athletes to those who did RTP, and evaluate the SLAP-Return to Sport after Injury (SLAP-RSI) score to assess the psychological readiness of athletes to RTP after operative management of SLAP tears. A retrospective review of athletes who underwent operative management of SLAP tears with a minimum of 24-month follow-up was performed. Outcome data, including visual analog scale (VAS) score, Subjective Shoulder Value (SSV), American Shoulder & Elbow Surgeons (ASES) score, patient satisfaction, and whether they would undergo the same surgery again was collected. Additionally, the rate and timing of return to work (RTW), the rate and timing of RTP, SLAP-RSI score, and VAS during sport were evaluated, with subgroup analysis among overhead and contact athletes. The SLAP-RSI is a modification of the Shoulder Instability-Return to Sport after Injury (SI-RSI) score, with a score >56 considered to be a passing score for being psychologically ready to RTP. The study included 209 athletes who underwent operative management of SLAP tears. A significantly higher percentage of patients who were able to return to play passed the SLAP-RSI benchmark of 56 compared to those who were unable to return (82.3% vs 10.1%; P < .001), and the mean overall SLAP-RSI scores were also significantly higher among those capable of returning to play (76.8 vs 50.0; P < .0001). Additionally, there was a significant difference between the two groups in every component of the SLAP-RSI score (P < .05 for all). Fear of reinjury and the feeling of instability were the most common reasons for not returning to play among contact athletes. Residual pain was the most common complaint among overhead athletes. A binary regression model predicting return to sports was performed, which demonstrated ASES score (odds ratio [OR]: 1.04, 95%; (confidence interval [CI]: 1.01-1.07; P= .009), RTW within 1 month after surgery (OR: 3.52, 95%; CI: 1.01-12.3; P= .048), and SLAP-RSI score (OR: 1.03, 95%; CI: 1.01-1.05; P= .001) were all associated with greater likelihood of return to sports at final follow-up. Following the operative management of SLAP tears, patients who are unable to RTP exhibit poor psychological readiness to return, which may be due to residual pain in overhead athletes or fear of reinjury in contact athletes. Lastly, the SLAP-RSI tool in combination with ASES proved to be useful in identifying patients' psychological and physical readiness to RTP. Level IV, prognostic case series.

Arthroscopic Repair of a Type VIII Superior Labrum Anterior Posterior Tear

Background: Type VIII superior labrum anterior posterior (SLAP) tears are described as SLAP type II tears with posterior extension to the posterior inferior glenohumeral ligament. These tears are a common source of pain, instability, and decreased function in active individuals, particularly overhead or throwing athletes. Indications: Type VIII SLAP tears can cause pain and loss of sports performance, especially in a throwing athlete. This patient is a quarterback and pitcher who had magnetic resonance imaging and arthroscopic evidence of a type VIII SLAP tear with pain and inability to throw at his preinjury level. Technique Description: In the lateral decubitus position, a standard posterior portal is established along with anterior and accessory lateral portals. A type VIII SLAP tear is identified and the arm is taken out of balanced suspension traction and placed in abduction and external rotation which shows displacement of the posterior labrum and peelback of the superior labrum indicating pathologic labral instability. The labrum is then elevated and glenoid prepared to achieve healthy bleeding bone. Tape sutures are then passed around the labrum and placed into a glenoid anchor starting superiorly and continuing the repair posteroinferiorly. Three anchors were placed in the superior labrum using a percutaneous technique, with 2 more placed from the posterior portal to complete the 5-anchor repair. The posterior portal is then closed with a single monofilament suture to prevent a potential stress riser in the capsule. Results: The literature suggests that athletes with type VIII SLAP tears can expect improved functional outcomes and high return to play rates (&gt;90%); however, only 50% to 70% of throwing athletes return to the same level of play. Discussion/Conclusion: Type VIII SLAP tears are an important cause of shoulder pain and dysfunction, particularly in overhead athletes. Arthroscopic repair of type VIII SLAP tears can improve functional outcomes and ability to return to sport; however, throwing athletes experience lower rates of return to previous level.

Superior and Anterior Glenoid Labral Tears Are Associated With Increased Neurofilament Concentration

Background: Pain is a common presentation after glenohumeral labral injuries. However, the source of that pain is undetermined. Purpose/Hypothesis: We aimed to determine if there is a differential expression of nerve fibers around the glenoid labrum and if torn labra have increased neuronal expression compared with untorn labra (rotator cuff repair labra). We hypothesized that the superior labrum would have a higher concentration of neurofilament than would the rest of the labrum and that the concentration of neurofilament would increase at the site of a labral tear. Study Design: Descriptive laboratory study. Methods: Seven labra were sampled at the 3-, 5-, 9-, and 12-o’clock positions during total shoulder arthroplasty. Samples were also collected at the 3-, 5-, and 12-o’clock positions during rotator cuff repair (16 labra), anterior labral repair (6 labra), type II superior labral anterior to posterior (SLAP) repair (4 labra), and capsular release for idiopathic capsulitis (5 labra). Sections were immunostained with antibodies to neurofilament, a specific neuronal marker that is used to identify central and peripheral nerve fibers, and the concentration and intensity of immunostained-positive cells assessed. Results: The concentration of neurofilament staining was similar in the superior, anterior, posterior, and inferior glenoid labrum in untorn labra (8 neurofilament expressing cells per square millimeter; P = .3). Torn labra exhibited a 3- to 4-fold increase in neuronal expression, which was isolated to the location of the tear in SLAP (P = .09) and anterior labral tears (P = .02). The concentration of neurofilament expressing cells in torn glenoid labrum samples was comparable that in with the glenoid labrum of adhesive capsulitis samples (P = .7). Conclusion: This study supports the hypothesis that after a tear of the anterior or superior labrum the labrum in that region becomes populated with new nerves fibers and that these fibers may be responsible for the pain noted by patients with superior (SLAP) and/or anterior labral (Bankart) tears. Clinical Relevance: This study suggests that neural infiltration contributes to the pain experienced by patients with labral tears. It may help with patient education and direct future management of labral lesions.

The O'Brien test demonstrates a higher diagnostic value in identifying posteroinferior labral tears than superior labral anterior to posterior (SLAP) tears.

The primary aim was to determine the diagnostic value of the O'Brien test in localizing labral tears of the shoulder. A consecutive series of patients electing for labral repair between January 2005 and March 2021 were included in this retrospective study. Inclusion criteria were as follows: (1) any patient with a labral tear who was elected for arthroscopic labral repair and (2) had documentation of the O'Brien test in the preoperative evaluation. Exclusion criteria were patients that had a negative arthrographically enhanced computed tomography or magnetic resonance imaging scan. During arthroscopy, the localization and extension of the labral tear was documented in a standardized 12-o'clock configuration. Anteroinferior, posteroinferior, superior labrum anterior to posterior (SLAP), and combined labral tears were documented. The sensitivity, specificity, positive and negative predictive values, accuracy, positive and negative likelihood ratios, receiver operating characteristic curve, and area under the curve were calculated to determine the diagnostic value. The cohort consisted of 271 patients (77% male) and included 105 anteroinferior, 86 posteroinferior, 46 SLAP, and 32 combined parts of the labrum. The mean age at time of surgery was 30 (±10.2) years. The O'Brien test was positive in 142 (52%) patients and showed the highest sensitivity and specificity for the posteroinferior tears (83% and 62%) compared to the anteroinferior (16% and 25%), combined labral parts (69% and 50%), and SLAP (65% and 50%) tears. In addition, receiver operating characteristic-analysis demonstrated a significantly higher area under the curve for posteroinferior tears compared to the other tears (P<.001). The O'Brien test demonstrates more diagnostic value for posteroinferior tears than other labral tears. This includes the SLAP tear, for which the O'Brien test was originally designed. These findings are helpful towards reinterpreting the O'Brien test as well as diagnosing, and more specifically localizing labral tears in clinics.

SLAP repair and bicep tenodesis: a comparison of utilization and revision rates for SLAP tears

The management of superior labrum anterior to posterior (SLAP) tears typically consists of either repair or biceps tenodesis (BT). While repair is more frequently recommended in younger patients, patients older than 40 years are often treated with BT. The purpose of this study is to determine whether there has been a change in utilization of these procedures over the past decade with respect to patient age as well as compare reoperation rates between the two procedures. The Pearldiver database was queried to identify BT and SLAP repairs indicated for SLAP tears performed from 2010 to 2019. The primary outcome was utilization rate, stratified by age. A secondary outcome was 2-year shoulder reoperation rates. Trends were reported in terms of compounded annual growth rate. Outcome analysis was conducted using univariate and multivariable analysis. From 2010 to 2019, SLAP repair was the most common procedure performed for SLAP tears. Regardless of age, BT performed for SLAP tear had a significantly increased utilization rate; whereas, SLAP repair had a significantly decreased utilization rate. SLAP repair was more commonly performed in younger patients compared to BT. Following multivariable analysis, patients who underwent SLAP repair had significantly higher odds (odds ratio (OR): 1.453; 95% confidence interval (CI): 1.26-1.68; P<.001) of requiring an arthroscopic reoperation within 2 years when compared to those who underwent BT with no significant difference with respect to 2-year open reoperation. Although SLAP repair is still more commonly used to treat SLAP tears than BT, especially for younger patients, the utilization of SLAP repair is decreasing while BT is increasing. The increased utilization of BT may be associated with lower rates of shoulder reoperation for problematic SLAP tears.

Current Best Treatment for Superior Labrum, Anterior to Posterior Tears

<h3>Objective(s)</h3> To investigate the current best treatment approach in regards to surgical and non-surgical approaches for Superior Labrum, Anterior to Posterior (SLAP) tears in the young athlete and older working adult population. <h3>Data Sources</h3> Google Scholar, PubMed, and ScienceDirect were searched for the terms(SLAP repair, biceps tenodesis, SLAP lesion, arthroscopic SLAP repair, and SLAP treatment).The search was limited to articles published between 2017 to present, English language and human participants. <h3>Study Selection</h3> Studies were selected based on approaches to SLAP tear i.e.: conservative rehabilitation, biceps tenodesis, SLAP repair, and combined biceps tenodesis with SLAP repair. From 31 articles that were initially adopted, 23 were selected and included in our review. <h3>Data Extraction</h3> Three reviewers independently reviewed each article and noted information provided in each article. The information included treatment methods (surgical vs rehabilitative) as well as differences in surgical approaches, return to play after various treatment methods, and cost analysis of various surgical approaches. <h3>Data Synthesis</h3> Individuals older than 35-40 with biceps tenodesis have lower risks of complications and revisions, decreased stiffness, less pain, and higher satisfaction rates with BT. SLAP repairs show better outcomes with younger athletes, SLAP repair in overhead athletes often leds to additional surgeries. However, no significant differences were found between the SLAP repair and BT for the overhead athletes. A combined SLAP repair and BT approach has shown the worst outcomes with less mobility, lower outcome measure scores, and increased pain. A conservative approach for 3 to 6 months however, is recommended before surgical options are considered. <h3>Conclusions</h3> Based on the current evidence, it appears that BT is an optimal choice for younger, less competitive athletes, as well as those individuals above the age of 35. Less favorable outcomes have been reported with the BT approach for competitive athletes and baseball pitchers; therefore, the healthcare team must work closely to determine the next best option on an individual basis. <h3>Author(s) Disclosures</h3> There are no conflict of interest associated with this study for any of the authors.

Quality Assessment of YouTube Content on SLAP Tears

ABSTRACT Objectives Superior labrum anterior posterior (SLAP) tears can cause shoulder pain, disability, instability, and humeral head translation. YouTube has become an increasingly popular source of medical information, but little is currently known in terms of quality control of the uploaded content. The purpose of this study was to assess the quality of YouTube videos related to the diagnosis and treatment of Superior Labrum Anterior Posterior (SLAP) tears. Methods YouTube was queried in August 2021 using the two predetermined keywords: ‘SLAP tear’ and ‘superior labral tear.’ The first 50 videos were analyzed by two independent reviewers and scored using 3 scoring systems: Global Quality Scale (GQS), the Journal of the American Medical Association (JAMA), and the Shoulder-Specific Score (SSS) to determine video accuracy and reliability. Title, number of views, video duration, video source, content type, views/day, number of likes, number of dislikes, days since upload, like ratio (Like × 100/ [Like + Dislike]) and Video Power Index (VPI) (Like ratio × View ratio/100) were all recorded and analyzed. Results The scores of most videos were low, with a mean JAMA score of 2.5 (1–4, SD 0.73), a mean GQS of 2.66 (0.5–4.5, SD 0.99) and a mean SSS of 7.13 (0–18, SD 4.39). There were significantly higher mean scores for JAMA, GQS, and SSS in the academic and independent physician categories, with a mean JAMA score of 3.11, GQS score of 3.39, and SSS score of 11 for academic sources and a mean JAMA score of 2.83, GQS score of 3.23, and SSS score of 9.23 for independent physician sources. JAMA score was significantly and positively correlated with video duration (r = 0.405, p = 0.006). Views, likes, dislikes, publication dates, and VPI were not significantly correlated with any scoring scale. Conclusion YouTube videos on the diagnosis and management of SLAP tears have low overall quality and reliability scores. Independent physician and academic institution sources received higher mean scores for JAMA, GQS, and SSS. Video quality was not correlated with number of views.

Risk factors for the development of Superior Labrum Anterior to Posterior (SLAP) tears in physically demanding occupations: a systematic review and meta-analysis

Background: Currently, available evidence indicates people in physically demanding occupations (e.g., military or sport) may be at a higher risk of injury to the labrum than other occupations, with mechanisms involving acute forceful trauma or sustained mechanical forces exerted across the shoulder or hip joint. Therefore, the aim of this systematic review was to identify and synthesise findings from studies which reported the incidence or prevalence of Superior Labrum Anterior to Posterior (SLAP) tears in physically demanding occupations, and the risk factors associated with their development. Methods: This review was conducted according to the PRIMSA-P guidelines and registered on the Open Science Framework. PubMed, EBSCO, Scopus, Web of Science, CINAHL and ProQuest databases were systematically searched using the following key terms: ‘labral tear’, ‘work’ and ‘risk’. Key findings from the included studies were extracted, including risk factors, prevalence or incidence and risk ratios (e.g., relative risk, hazard ratios, and incidence rate ratios). Each study included in the review was critically appraised to assess its methodological quality, using the Critical Appraisal Skills Programme (CASP) toolkit for cohort studies, and the Joanna Briggs Institute (JBI) case series critical appraisal tool for a case series study. Meta-analysis was conducted using the Cochrane Collaborations software package, Review Manager (RevMan, version 5.3). A random effects model was selected due to the variability in participant demographics and other characteristics across the included studies. OR and 95% CI were calculated. Results: Six articles met the eligibility criteria, and these included three studies on professional athlete populations, two on military populations, and one study reporting on SLAP tears arising from workplace accidents or as a condition arising from occupational tasks. The methodological quality scores of the included studies ranged from 50% to 92%, with an average score of 73%. SLAP tears comprised 3.1% of shoulder injuries recorded over a 15-year period in the NFL and reported incidence in military populations was 2.13 [95% CI 2.11 to 2.16] per 1,000 person-years. Identified risk factors include younger age, male sex, acute weight-bearing and overhead movements, gameplay (as opposed to training), Army or Marine Corps service and enlisted rank. Meta-analysed data comprised from the military and sporting population studies, indicated strong evidence (p < 0.001; OR 11.40 [95% CI 5.65 to 23.02]; I2 = 35%) for the role of direct contact or trauma in developing SLAP tears compared to indirect or non-contact tasks. Discussion: The findings showed individuals of male sex and of younger age, are at increased risk of sustaining SLAP tears. The results of the meta-analysis provided strong evidence that direct contact or trauma to the glenohumeral joint resulting from collisions or force directed to the shoulder from an abducted arm position was more likely to be associated with shoulder labrum tears (primarily SLAP, although inclusive of Bankart and other labral tears) than other forms of indirect force applied to the shoulder or non-contact mechanisms. Impact: Tackling, blocking, collisions, repeated overhead shoulder lifting, combat sports, and sporting tasks predispose physically demanding occupations to increases in SLAP injury risk. Conflict of interest statement: This research was funded by the Department of Veterans’ Affairs.
