Biceps tenodesis versus labral repair for superior labrum anterior-to-posterior tears: a systematic review and meta-analysis

Type V superior labrum anterior to posterior repair: a systematic review

BACKGROUND

The purpose of this study is to systematically review the evidence in the literature to ascertain the functional outcomes, recurrence rates, and subsequent revision rates following type V superior labrum anterior to posterior (SLAP) repair.

METHODS

Two independent reviewers performed a literature search based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, utilizing the EMBASE, MEDLINE, and the Cochrane Library Databases. Studies were included if they had clinical outcomes on the patients undergoing type V SLAP repair. Statistical analysis was performed using SPSS (IBM, Armonk, NY, USA). A P value of <.05 was considered to be statistically significant.

RESULTS

Our review found 13 studies, including 451 shoulders meeting our inclusion criteria. The majority of patients were males (89.3%), with an average age of 25.9 years (range 15-58) and a mean follow-up of 53.8 months. The Rowe score was the most utilized functional outcome score, with a weighted mean of 88.5. Additionally, the mean Constant score was 91.0, the mean American Shoulder and Elbow Surgeons score was 88.3, the mean subjective shoulder value score was 85.5%, and the mean visual analog scale pain score was 1.2. The overall rate of return to play was 84.8%, with 80.2% returning to the same level of play. The overall reoperation rate was 6.1%, with a recurrent dislocation rate of 8.2%. In the studies comparing type V SLAP and isolated Bankart repair, there were statistically insignificant differences in visual analog scale pain scores (mean difference; 0.15, 95% confidence interval, -0.13 to 0.44, I2 = 0%, P = .29) and recurrence rates (risk ratio; 1.38, 95% confidence interval, 0.88-2.15, I2 = 0%, P = .16).

CONCLUSION

Arthroscopic repair of type V SLAP tears results in excellent functional outcomes, with high return to play rates in athletes. There are low rates of reoperations and recurrent dislocations. Additionally, in comparison to an isolated Bankart repair, SLAP repair does not increase recurrence rates or postoperative pain.

Superior labrum anterior to posterior (SLAP) repair is associated with increased rate of subsequent rotator cuff diagnoses and revision surgery: a propensity-matched comparison

BACKGROUND

Surgical management of superior labral anterior to posterior (SLAP) tears remains controversial. Current management utilizes 2 well-established procedures: biceps tenodesis and SLAP repair. This study evaluates the complications associated with arthroscopic SLAP repair vs. an open or arthroscopic biceps tenodesis to further elucidate optimal surgical management.

METHODS

In this retrospective cohort study, the TriNetX database was utilized to evaluate patients who underwent repair of SLAP lesions (International Classification of Diseases, Tenth Revision code: S43.43) from May 15, 2003, to May 15, 2023. Three patient cohorts were evaluated: those who underwent arthroscopic SLAP repair (Current Procedural Terminology [CPT] code: 29807), those who underwent arthroscopic biceps tenodesis (CPT code: 29828), and those who underwent open tenodesis of the biceps (CPT code: 23430). Cohorts were propensity matched for type 2 diabetes, nicotine dependence, alcohol-related disorders, body mass index, and demographic factors such as age at event, ethnicity, race, and sex. The outcomes evaluated were disruption of surgical wound, deep vein thrombosis, mononeuropathy of upper limb, shoulder contusion, humeral fracture, sepsis, deceased, acute postoperative pain, revision, shoulder stiffness, and rotator cuff strain. All outcomes were evaluated within 1 year postprocedure.

RESULTS

A total of 11,081 arthroscopic SLAP repairs, 9960 arthroscopic biceps tenodesis, and 9420 open biceps tenodesis were matched. Compared with patients who underwent arthroscopic biceps tenodesis, those who underwent arthroscopic SLAP repair were 1.8 times more likely to undergo revision (2.9% vs. 1.6%, P < .0001). Compared with those who underwent open biceps tenodesis, patients who had SLAP repair performed were 1.4 times more likely to undergo revision (3.1% vs. 2.3%, P = .013) and 1.6 times more likely to have a subsequent rotator cuff strain diagnosis (5.1% vs. 3.2%, P = .0002). Compared with patients who underwent SLAP repair, those who underwent arthroscopic biceps tenodesis exhibited 1.3 times more instances of acute postoperative pain (5.2% vs. 4.0%, P = .011). Similarly, open biceps tenodesis exhibited 1.8 times more instances of acute postoperative pain (6.9% vs. 3.8%, P < .0001) and 1.3 times more shoulder stiffness (11.8% vs. 9.0%, P < .0001).

CONCLUSION

In the last 20 years, patients who underwent SLAP repair were associated with higher risk of revision surgery and subsequent rotator cuff strain diagnosis. Conversely, patients who underwent biceps tenodesis were associated with higher rates of acute postoperative pain and shoulder stiffness.

Similar outcomes between biceps tenodesis and SLAP repair for SLAP tears in younger patients - A meta-analysis

OBJECTIVES

The purpose of this study is to systematically review the comparative studies in the literature to ascertain if biceps tenodesis or superior-labrum anterior to posterior (SLAP) repair results in superior clinical outcomes in the treatment of type II SLAP tears in patients under 40.

METHODS

A systematic search of articles in Pubmed, EMBASE and The Cochrane Library databases was carried out according to the PRISMA guidelines. Cohort studies comparing biceps tenodesis to repair in type II SLAP tears in patients under 40 were included. Clinical outcomes were extracted including return to play, reoperations, ASES, and VAS for pain. All statistical analysis was performed using Review Manager. A p-value of <0.05 was considered to be statistically significant.

RESULTS

Five studies were included. Biceps tenodesis resulted in comparable rates of return to play compared to SLAP repair (78.5% vs 67.7%, p ​= ​0.33), and there was no significant difference in return to play in overhead athletes (83.6% vs 74%, p ​= ​0.82). There was no significant difference in ASES score (87.2 vs 86.2, p ​= ​0.27) or VAS score for pain (1.8 vs 2.1, p ​= ​0.48). There was no significant difference in re-operation rates (2.9% vs 10.8%, p ​= ​0.22).

CONCLUSION

This study found that biceps tenodesis has no significant difference in rates of return to play in athletes, as well as in functional outcome scores and rates of revision surgery in younger patients compared to SLAP repair.

Gender does not impact clinical outcomes following SLAP repair

Background

The purpose of the current study was to investigate whether pain, function, satisfaction, return to play (RTP), or psychological readiness to RTP differ between sexes post-operatively following SLAP repair.

Methods

A retrospective review of patients who underwent arthroscopic repair of a SLAP tear was performed. The American Shoulder & Elbow Surgeons (ASES) score, Visual Analogue Scale (VAS), Subjective Shoulder Value (SSV), patient satisfaction, willingness to undergo surgery again, revisions, and return to play (RTP) were evaluated. Clinical outcomes were compared between male and female patients.

Results

Our study included 169 patients treated with SLAP repair, 133 of them male (78.7%) and 36 of them female (21.3%), with an average age of 32.3 ± 8.3 and 33.4 ± 6.8 respectively. The mean follow-up duration was 5.8 years. At final follow up, there was no difference between treatment groups in any of the functional outcome measures assessed (p > 0.05).

Conclusion

There is no difference in clinical outcomes, function, satisfaction, or revision procedures in mid- to long-term follow-up after SLAP repair between male and female patients. This data is useful in the preoperative counselling of patients undergoing arthroscopic management of symptomatic superior labral pathology.

Physical Examination Maneuvers for SLAP Lesions: A Systematic Review and Meta-analysis of Individual and Combinations of Maneuvers

BACKGROUND

Superior labrum anterior to posterior (SLAP) lesions are targeted on physical examination using a variety of provocative maneuvers.

PURPOSE/HYPOTHESIS

The purpose was to conduct a systematic review on the performance of physical examination maneuvers in diagnosing SLAP lesions and to perform a meta-analysis comparing the sensitivity and specificity of these examinations both individually and in combination. The null hypothesis stated that there would be no significant difference in the sensitivity or specificity of the included physical examination tests, neither individually nor in combination.

STUDY DESIGN

Meta-analysis and systematic review; Level of evidence, 4.

METHODS

A systematic review was performed with the inclusion criteria of studies that reported either the sensitivities and specificities or the number of true-positive, true-negative, false-positive, or false-negative results for at least 1 maneuver for identifying SLAP lesions. A meta-analysis was performed to determine the sensitivity and specificity of individual maneuvers. Additional analysis determined the performance of these maneuvers when combined in series and parallel. In series, all must be present to be considered positive. In parallel, any single positive test forces the overall combination to be considered positive. Only tests that were included in ≥3 studies were considered in the meta-analysis and those included in ≥4 studies were considered in the combination analysis.

RESULTS

Overall, 862 studies were identified, 18 of which were included in the systematic review and meta-analysis. The physical examinations included were the O'Brien (n = 16), speed (n = 8), Yergason (n = 6), anterior slide (n = 8), crank (n = 7), Jobe (n = 5), dynamic labral shear (n = 3), Kim 2 (n = 3), and biceps groove tenderness tests (n = 3). All combinations of 2 to 5 maneuvers in both series and parallel were considered. The O'Brien and crank test combination was the most sensitive 2-test combination in both parallel and series. The Yergason and anterior slide test combination was the most specific 2-test combination in parallel and series.

CONCLUSION

This systematic review and meta-analysis reports an updated meta-analysis considering the sensitivity and specificity of common physical examination maneuvers used in the diagnosis of SLAP lesions and considers these values for tests in both series and parallel combinations. The present analysis demonstrates improved specificities when tests are considered in series and improved sensitivities when considered in parallel combination.

Arthroscopic In Situ Biceps Tenodesis Using a Double Loop-and-Tack Knotless Suture Anchor

The long head biceps tendon is a common culprit of anterior shoulder pain and dysfunction that can be surgically treated with tenotomy or tenodesis. Many techniques exist for tenodesis. This article submits an arthroscopic technique using two loop-and-tack sutures and a knotless suture anchor to tenodese the long head biceps tendon in the proximal bicipital groove in situ. The advantage of this technique is that it maintains the biceps in its native position by performing tenodesis before tenotomy. Most other techniques attempt to restore native position of the biceps through approximation. The transverse humeral ligament is also released to decompress the bicipital groove. This technique can be used to treat isolated biceps pathology or combined with rotator cuff and labral procedures.

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.

Superior-Labrum Anterior-Posterior Tears

Purpose

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.

Methods

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.

Results

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.

Conclusions

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.

Biceps Tenodesis cannot be used as primary treatment option in baseball pitchers with intact rotator cuff muscles

Background Surgeons remain hesitant to perform biceps tenodesis in athletes with type II superior labrum anterior-to-posterior tears due to the lack of reported clinical outcomes for individual overhead throwing sports and associated concerns that this may predispose the joint to instability. This study aimed to assess the effect of biceps tenodesis on shoulder stability for major overhead throwing sports to aid sport-specific surgical decision-making for athletes with type II superior labrum anterior-to-posterior tears.

METHODS

This is a combined modelling and experimental study. Motion data and external forces were measured from 13 participants performing five overhead throwing motions. These data served as input into a musculoskeletal shoulder model that quantifies shoulder stability and muscle loading.

FINDINGS

The loading of the long head of the biceps brachii decreases significantly following biceps tenodesis in three overhead throwing motions (p = 0.02). The loss in joint stability following biceps tenodesis is compensated by a non-significant increase in rotator cuff muscle force which maintains shoulder stability across all overhead throwing motions, except baseball pitching (p = 0.01). The presence of a full-thickness supraspinatus tear post biceps tenodesis further decreases shoulder stability in four of the five overhead throwing motions (p = 0.01).

INTERPRETATION

The study findings demonstrate that an increase in rotator cuff muscle force maintains joint stability for all overhead throwing motions post biceps tenodesis, except baseball pitching. As the presence of a full-thickness tear of the supraspinatus significantly reduces joint stability, biceps tenodesis may be used as a primary treatment in overhead throwing athletes with intact rotator cuff muscles, except baseball pitchers.

Primary Biceps Tenodesis Is Superior to Revision Following Failed SLAP Repair

Purpose

To compare satisfaction and return to play (RTP) rates between patients undergoing primary biceps tenodesis for a symptomatic SLAP tear and patients undergoing secondary biceps tenodesis following a failed SLAP repair.

Methods

A retrospective review of patients who underwent subpectoral mini-open biceps tenodesis following failed SLAP repair between January 2011 and October 2019 was performed. Inclusion criteria included age older than 16 years, skeletal maturity, and a minimum follow-up of 12 months. Both athletes and nonathletes were included across all types of sport. Patients who had anterior or posterior instability or rotator cuff tears were excluded; in addition, those requiring concomitant procedures were excluded. Case-control matching was performed using age, sex, indication, follow-up, and type of sport, to generate a 3:1 control group for the primary biceps tenodesis cohort. Primary outcome measurements were collected via telephone in 2020 and included the American Shoulder and Elbow Surgeons score, visual analog scale score, Subjective Shoulder Value score, patient satisfaction, willingness to undergo surgery again, and revisions. RTP and timing of RTP were evaluated as secondary outcomes. A P value of <.05 was considered to be statistically significant.

Results

The current study included 76 patients in total; 57 patients with primary biceps tenodesis, and 19 patients with secondary biceps tenodesis. The mean age was 39 years (19-48 years), 100% were male, and the mean follow-up was 54 months (16-99 months). Patient reported outcomes were obtained postoperatively via telephone survey. Overall, we found that primary biceps tenodesis patients reported greater American Shoulder and Elbow Surgeons scores (89.9 vs 76.4, P = .0162), lower visual analog scale scores (1.0 vs 3.1, P = .0034), and greater Subjective Shoulder Value scores (86.7 vs 64.7, P = .0004). Overall, there was no significant difference in the total rate of RTP (84% vs 75%, P = .5025), or timing of RTP (8.2 months vs 8.1 months, P = .9529) between patient groups. Patients reported playing tennis, swimming, golf, rock climbing, and basketball. No patients required a further shoulder surgery after undergoing biceps tenodesis.

Conclusions

In this study, patients undergoing primary biceps tenodesis had significantly better functional outcomes compared with secondary biceps tenodesis following a failed SLAP repair.

Biceps Tenodesis Combined With Arthroscopic Posterior Labral Repair for Type VIII SLAP Lesions in Active-Duty Military Patients Yields Excellent Return to Military Duty

PURPOSE

To report short-term outcomes following biceps tenodesis combined with arthroscopic posterior labral repair of type VIII SLAP lesions in active-duty military patients.

METHODS

All consecutive patients from January 2012 through December 2018 who underwent biceps tenodesis combined with arthroscopic posterior labral repair of type VIII SLAP tears performed by the senior surgeon with complete outcome scores and minimum 2.5 years follow-up were identified. Exclusion criteria included concomitant glenoid microfracture, rotator cuff repair, or other capsulolabral repair. Outcome measures were completed by patients within 7 days before surgery and at latest follow-up. Biceps tenodesis performed was a mini-open, through a subpectoral approach, using a double-loaded 2.9mm suture-anchor.

RESULTS

Thirty-two patients met the inclusion criteria for the study. All patients were active-duty military at time of surgery. Average follow-up was 73.53 ± 22.37 months. Thirty-one patients achieved the minimal clinically important difference, 30 of 32 reached the substantial clinical benefit, and 31 of 32 met the patient acceptable symptomatic state, as defined for the American Shoulder and Elbow Surgeons Shoulder Score. Similarly, 30 of 32 patients reached the minimal clinically important difference, 29 of 32 achieved the substantial clinical benefit, and 32 of 32 met the patient acceptable symptomatic state for the Single Assessment Numeric Evaluation. There were no significant changes in forward flexion, external rotation, or internal rotation between pre- and postoperative measurements. Three patients reported postoperative complications and 1 patient progressed to further surgery. Thirty (93.75%) patients remained on active-duty military service and were able to return to preinjury levels of activity.

CONCLUSIONS

Active-duty military patients with type VIII SLAP tears had statistically and clinically significant increases in outcome scores, marked improvement in pain, and high rates of return to unrestricted active-duty following mini-open subpectoral biceps tenodesis combined with posterior labral repair.

Concomitant Cervical Spine Stenosis Negatively Affects Subpectoral Biceps Tenodesis Outcomes

Purpose

To determine whether an association exists between the presence of cervical spine pathology and postoperative patient-reported outcomes (PROs) in patients undergoing open subpectoral biceps tenodesis (BT).

Methods

A retrospective review of patients undergoing isolated BT from August 2011 to May 2019 was conducted. Cases were defined as patients with concomitant cervical spine disease (disc disease, disc herniations, neuroforaminal/central stenosis). Controls were patients without cervical spine disease. Postoperative PROs were collected from all patients with a minimum of 12-month follow-up. Cases and controls were matched 1:1 using age and body mass index. PROs were compared using the χ² text, Fisher exact test, or analysis of variance.

Results

A total of 23 cases and 23 controls were identified. Cases and controls had similar distributions of age (42.4 ± 4.4 years, 40.4 ± 4.5, P = .15), sex (83% male, 87% male, P = .68), body mass index (28.0 ± 4.0, 27.6 ± 4.3, P = .78), and percentage of athletes (65% athlete, 61% athlete. P = .76). All cases had evidence of neuroforaminal stenosis and multilevel degenerative disc disease, whereas 19 of 23 (83%) had evidence of central canal stenosis. Cases had a greater visual analog scale (VAS) score during Sport score (3.6 ± 0.7 vs 1.2 ± 0.6, P = .013) and lower Subjective Shoulder Value (69.5 ± 5.8 vs 84.1 ± 5.4, P = .070) and Shoulder Instability-Return to Sport after Injury score (60.4 ± 5.8 vs 77.4 ± 6.0, P = .046). There were no significant differences between groups’ ASES, baseline VAS, overall satisfaction scores, and willingness to undergo the same operation again. No significant differences were found in postoperative rate of return to sport, time to return, and return to preoperative competitiveness.

Conclusions

Patients with SLAP tears undergoing isolated BT in the presence of cervical spinal stenosis may have inferior Subjective Shoulder Value, Shoulder Instability-Return to Sport after Injury, and VAS during sport scores as compared with controls, although many PROs were similar at follow-up. Athletes undergoing BT, particularly with concomitant cervical spine pathology, should be counseled appropriately before surgery.

High Rate of Satisfaction and Return to Play at 5-Year Follow-Up After Arthroscopic Superior-Labrum Anterior-Posterior Repairs

PURPOSE

The purpose of this study was to evaluate the outcomes of patients 5 years postoperatively following arthroscopic SLAP repair, and to evaluate factors associated with satisfaction.

METHODS

A retrospective review of patients who underwent SLAP repair with a minimum of 5-year follow-up was performed. Recurrence, visual analog scale (VAS) score, Subjective Shoulder Value (SSV), American Shoulder & Elbow Surgeons (ASES) score, satisfaction, whether they would undergo the same surgery again, and the rate, level and timing of return to play (RTP) were evaluated. Multilinear regression models were used to evaluate factors affecting postoperative satisfaction.

RESULTS

Overall, 122 patients who underwent SLAP repair were included, with a mean age of 33.4 years. 81% were males, and 58.2% were participating in sport preoperatively. The mean follow-up was 86.4 ± 14.4 months. At final follow up, the mean satisfaction was 87.7%, and the mean SSV was 82.9. Overall, the rate of RTP was 85.9%, with 64.8% returning at the same level at a mean of 10.5 ± 8 months. Ultimately, 13 (10.7%) patients had a further surgery, including 10 (8.2%) patients that had a biceps tenodesis. VAS during sport (P = .025), SSV (P < .001), and time to RTP (P = .0056), were associated with higher satisfaction.

CONCLUSION

There was a high rate of satisfaction at 5-year follow-up, with excellent patient-reported outcomes but with one-tenth of patients requiring revision surgeries. Additionally, while there was an overall high rate of RTP, there was only a modest rate of RTP at their preinjury level, and overhead athletes took longer to RTP.

Biceps Tenodesis Demonstrates Lower Reoperation Rates Compared to SLAP Repair for Treatment of SLAP Tears in a Large Cross-Sectional Population

PURPOSE

To use a contemporary cross-sectional data set to evaluate trends in surgical treatment for superior labrum anterior and posterior (SLAP) tears and compare surgical outcomes with respect to 2-year revision surgery rates following index SLAP repair versus biceps tenodesis (BT).

METHODS

Patients diagnosed with a SLAP tear between 2010 and 2017 were queried using the Mariner PearlDiver database and stratified by demographic variables and surgical treatment with arthroscopic SLAP repair or arthroscopic/open BT. From 2015 to 2017, Current Procedural Terminology (CPT) and International Classification of Diseases 10th revision (ICD-10) codes were used to track ipsilateral subsequent reoperation within 2-years of index surgery.

RESULTS

Between 2010 to 2017, 16.6% of 377,463 patients diagnosed with a SLAP tear underwent surgery (62.3% SLAP repair vs 37.7% BT). 52.4% of BT procedures were arthroscopic (47.6% open). The frequency of SLAP repairs decreased from 74.0% to 46.2% (61%), while the frequency of BTs increased from 26.0% to 53.8% (202%) during the study period. Patients under age 50 were more likely to undergo SLAP repair, and those undergoing BT were more likely to be over 50 with higher CCI and comorbidity risk. 6.3% of 16,186 patients identified with ICD-10 coding required reoperation within 2-years postoperatively. SLAP repair demonstrated a higher revision rate (6.8%; 95% CI, 6.3-7.4%) than BT (5.7%; 95% CI, 5.2-6.2%; P =.0002), (open 5.8% vs arthroscopic BT 5.5%). Arthroscopic debridement, including biceps tenotomy, revision SLAP repair, and revision BT were the most common subsequent procedures. Patients aged 40 to 49 had the highest rate of revision surgery (7.8%).

CONCLUSIONS

The treatment trend for SLAP tears is changing, with SLAP repair becoming significantly less utilized and BT now becoming the preferred option, especially in patients over 50. Arthroscopic and open BT demonstrated slightly lower risk for reoperation than SLAP repair.

SLAP Repair Versus Subpectoral Biceps Tenodesis for Isolated SLAP Type 2 Lesions in Overhead Athletes Younger Than 35 Years: Comparison of Minimum 2-Year Outcomes

Background:

It remains unclear if young overhead athletes with isolated superior labrum anterior-posterior (SLAP) type 2 lesions benefit more from SLAP repair or subpectoral biceps tenodesis.

Purpose:

To evaluate clinical outcomes and return to sport in overhead athletes with symptomatic SLAP type 2 lesions who underwent either biceps tenodesis or SLAP repair.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

A retrospective analysis of prospectively collected data was performed in patients who underwent subpectoral biceps tenodesis (n = 14) or SLAP repair (n = 24) for the treatment of isolated type 2 SLAP lesions. All patients were aged <35 years at time of surgery, participated in overhead sports, and were at least 2 years out from surgery. Clinical outcomes were assessed with the American Shoulder and Elbow Surgeons (ASES) score; Single Assessment Numerical Evaluation (SANE) score; Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score; and the 12-Item Short Form (SF-12) physical component score. Return to sport and patient satisfaction were documented. Clinical failures requiring revision surgery and complications were reported.

Results:

Preoperative baseline scores in both the tenodesis and SLAP repair groups were similar. There were no significant differences between the groups on any postoperative outcome measure: For biceps tenodesis versus SLAP repair, the ASES score was 92.7 ± 10.4 versus 89.1 ± 16.7, the SANE score was 86.2 ± 13.7 versus 83.0 ± 24.1, the QuickDASH score was 10.0 ± 12.7 versus 9.0 ± 14.3, and SF-12 was 51.2 ± 7.5 versus 52.8 ± 7.7. No group difference in return-to-sports rate (85% vs 79%; P = .640) was noted. More patients in the tenodesis group (80%) reported modifying their sporting/recreational activity postoperatively because of weakness compared with patients in the SLAP repair group (15%; P = .022). One patient in each group progressed to surgery for persistent postoperative stiffness, and 1 patient in the tenodesis group had a postoperative complication related to the index surgery.

Conclusion:

Both subpectoral biceps tenodesis and SLAP repair provided excellent clinical results for the treatment of isolated SLAP type 2 lesions, with a high rate of return to overhead sports and a low failure rate, in a young and high-demanding patient cohort. More patients reported modifying their sporting/recreational activity because of weakness after subpectoral tenodesis.

Arthroscopic Modified Double-Row Biceps Tenodesis versus Labral Repair for the Treatment of Isolated Type II SLAP Lesions in Non-Overhead Athletes

Objective

To evaluate the postoperative efficacy and the clinical outcomes of arthroscopic modified double‐row biceps tenodesis versus labral repair.

Methods

A retrospective study was conducted in 56 patients with isolated type II superior labrum anterior and posterior (SLAP) lesions from March 2015 to November 2018. Thirty patients (male:female = 17:13) were treated with labral repair, and 26 patients (male:female = 15:11) were treated with modified double‐row biceps tenodesis. The average age of the labral repair group and the modified double‐row biceps tenodesis group were 42.8 ± 10.6 and 40.9 ± 10.2 years, respectively. Pre‐ and postoperative assessments with the visual analog scale (VAS), University of California Los Angeles (UCLA), and American Shoulder and Elbow Surgeons (ASES) scores were compared between the two treatment groups. Additional outcome measures included patient satisfaction, the time to return to previous activities, workers' compensation status, and postoperative complications.

Results

At a 2‐year follow‐up, the tenodesis group showed significant differences in postoperative VAS (1.5 to 1.8, respectively; p = 0.008), patient satisfaction (92.3% vs. 46.7%, p < 0.001), and recovery time to return to their previous activities (6.8 ± 1.8 vs. 8.1 ± 1.5, p = 0.007) compared to the labral repair group; however, there was no significant difference in postoperative ASES and UCLA scores between the two groups. Additionally, one patient in the tenodesis group developed persistent postoperative stiffness, which was resolved by conservative treatment. In the labral repair group, two patients presented with persistent postoperative night pain, three developed persistent postoperative stiffness, and two required a subsequent capsular release.

Conclusions

Compared with the labral repair group, the arthroscopic modified double‐row biceps tenodesis showed more encouraging postoperative pain reduction, earlier recovery to previous activities, and higher patient satisfaction.

Midterm Outcomes After Arthroscopic Repair of Type VIII SLAP Lesions in Active Duty Military Patients Younger Than 35 Years

Background

Superior labrum from anterior to posterior (SLAP) lesions represent a significant cause of shoulder pain and disability among active duty members of the US military. However, few data exist regarding the surgical management of type VIII SLAP lesions.

Hypothesis

We hypothesized that arthroscopic repair would decrease pain and increase function at the midterm follow-up and allow for a high rate of maintenance of active duty status.

Study Design

Case series; Level of evidence, 4.

Methods

Consecutive active duty military patients were identified from January 2011 through June 2015 who underwent arthroscopic repair of type VIII SLAP lesions performed by a single surgeon. Patients were excluded if they underwent glenoid microfracture, other capsulolabral repair, or rotator cuff repair. Outcome measures were completed by patients within 1 week before surgery and at latest follow-up: pain visual analog scale, Single Assessment Numeric Evaluation, American Shoulder and Elbow Surgeons shoulder score, and Rowe instability score.

Results

A total of 30 patients met the inclusion criteria for the study. The mean ± SD follow-up was 96.60 ± 10.91 months. At final follow-up, the mean visual analog scale score improved from 8.17 ± 1.6 to 1.63 ± 1.90 (P < .0001), the Single Assessment Numeric Evaluation score from 41.65 ± 16.78 to 87.63 ± 13.02 (P < .0001), the American Shoulder and Elbow Surgeons score from 36.47 ± 10.26 to 88.07 ± 13.94 (P < .0001), and the Rowe score from 35.33 ± 6.56 to 90.00 ± 14.68 (P < .0001). Three patients reported postoperative complications, and 1 progressed to further surgery. Overall, 90% of patients remained on active duty military service and were able to return to preinjury levels of work and recreational activity. The failure rate, defined as persistent instability or activity-limiting pain, was 10%.

Conclusion

The results of this study demonstrated favorable outcomes for the majority of patients after arthroscopic repair of type VIII SLAP lesions at midterm follow-up, supporting repair as a viable treatment option for type VIII SLAP tears in this patient population.

Return to Play After Biceps Tenodesis for Isolated SLAP Tears in Overhead Athletes

BACKGROUND

Performing open subpectoral biceps tenodesis in overhead athletes with a superior labrum anterior to posterior (SLAP) tear may affect their ability to return to overhead sports.

PURPOSE

To investigate clinical outcomes in overhead athletes undergoing biceps tenodesis for the treatment of symptomatic, isolated SLAP tears involving the biceps-labral complex.

STUDY DESIGN

Case series; Level of evidence, 4.

METHODS

A retrospective review of overhead athletes who underwent biceps tenodesis for a SLAP tear was performed. The American Shoulder and Elbow Surgeons (ASES) score, visual analog scale (VAS) score for pain, subjective shoulder value (SSV), patient satisfaction, willingness to undergo surgery again, revision procedures, and return to play were evaluated. Psychological readiness to return to sport was evaluated using the SLAP-Return to Sport after Injury (SLAP-RSI) score. A P value of <.05 was considered to be statistically significant.

RESULTS

The current study included 44 overhead athletes. The mean age was 34.9 years (range, 16-46 years), 79.5% were male, and the mean follow-up was 49.0 months (range, 18-107 months). Overall, 81.8% of patients returned to play their overhead sport after biceps tenodesis, and 59.1% of patients returned to the same or higher level of play. It took patients, on average, 8.7 months to return to play after biceps tenodesis. The mean SLAP-RSI score was 69.4, and 70.5% of patients passed the SLAP-RSI threshold of 56. The mean ASES score, VAS score, SSV, and satisfaction were 92.0, 0.8, 80.6, and 87.9%, respectively. No patients in our cohort required revision surgery.

CONCLUSION

This study found that athletes undergoing biceps tenodesis for the treatment of a symptomatic, isolated SLAP tear had a high rate of return to play, good functional outcomes, and a low rate of revision surgery.

Open Subpectoral Biceps Tenodesis May Be an Alternative to Arthroscopic Repair for SLAP Tears in Patients Under 30

PURPOSE

The purpose of the current study is to compare the outcomes of open subpectoral biceps tenodesis (BT) to arthroscopic repair (AR) for SLAP tears in patients under the age of 30 years.

METHODS

A retrospective review of patients under the age of 30 years who underwent either isolated BT or AR for a diagnosis of a SLAP tear between 2011 and 2019 was performed. Patients were included if they were >16 years old at the time of surgery, had an isolated SLAP tear involving instability of the biceps-labral anchor (types II-IV), were skeletally mature, and had a minimum follow-up of 12 months. The American Shoulder & Elbow Surgeons score, visual analog scale, Subjective Shoulder Value, patient satisfaction, willingness to undergo surgery again, revisions, and return to play (RTP) were evaluated. A P value of <.05 was considered statistically significant.

RESULTS

Our study included 103 patients in total; 29 patients were treated with BT, and 74 were treated with AR. The mean age was 24.8 years, and the mean follow-up duration was 60 months. At final follow-up, there was no difference between treatment groups in any of the functional outcome measures assessed (P > .05). Overall, there was no significant difference in the total rate of RTP (BT: 76.3%, AR: 85%; P = .53), timing of RTP (BT: 8.8 months, AR: 9.4 months; P = .61), and total rate of RTP among overhead athletes (BT: 84.2%, AR: 83.3%; P > .99). Among those undergoing AR, 9 required a revision procedure (11.5%) compared to none treated with BT (P = .11).

CONCLUSIONS

In patients under the age of 30 years with a symptomatic isolated SLAP tear, BT may be a reliable alternative to AR.

Current Controversies and Decision-Making in the Management of Biceps Pathologies

»

Biceps tendon pathologies include a spectrum of injuries that range from mild tendinosis to complete tendon rupture.

»

Tendinosis, the most common pathology, occurs more frequently with age and is likely related to chronic degeneration. On the other side of the spectrum of severity lies a rupture of the long head of the biceps tendon (LHBT), which may be accompanied by injury to the glenoid labrum.

»

Superior labral anterior-posterior (SLAP) tears are frequently associated with biceps pathology. Surgical management for injuries of the bicipital-labral complex includes biceps tenodesis or tenotomy and SLAP repair. A consensus as to which of these procedures is the optimal choice has not been reached, and management may ultimately depend on patient-specific characteristics.

»

Due to the relatively low incidence of distal biceps tendon rupture, agreement on the optimal management strategy has not been reached. Surgical repair, or reconstruction in the case of a chronic rupture, is often chosen. However, nonoperative management has also been utilized in older, less-active patients.

Concomitant Biceps Tenodesis Improves Outcomes for SLAP Repair: Minimum 2-Year Clinical Outcomes after SLAP II-IV Repair Versus Tenodesis Versus Both

Purpose

To investigate clinical outcomes, return to sport, and complication rate in patients with an isolated SLAP II-IV tear treated with biceps tenodesis (BT), SLAP-repair (SLAP-R), or both (SLAP-R+BT).

Methods

A retrospective analysis of prospectively collected data was performed in patients who underwent surgery between February 2006 and February 2018 for isolated SLAP II-IV lesions with either BT, SLAP-R, or SLAP-R+BT and had minimum 2-year follow-up. Patients were excluded if they were older than 45 years of age, had anterior shoulder instability, rotator cuff tears, glenohumeral osteoarthritis, or concomitant fractures about the shoulder. Clinical outcomes were assessed by the use of the American Shoulder and Elbow Society Score, Single Assessment Numerical Evaluation Score, Quick Disabilities of the Arm, and Shoulder and Hand Score, the General Health Short Form-12 Physical Component, and patient satisfaction.

Results

There were 38 shoulders in the isolated BT group with 1 (2.6%) shoulder requiring revision, 13 in the SLAP-R group with no patient requiring revision, and 21 in the SLAP-R+BT group with 2 (9.5%) shoulders requiring revision. Minimum 2-year follow-up was obtained in >85% of each group. Mean age at time of surgery was significantly different between the groups (36.5 years BT vs 27.7 years SLAP-R vs 36.5 years SLAP-R+BT; P = .003). While patient-reported outcomes improved significantly from pre- to postoperatively for the BT (P < .001) and SLAP-R+BT groups (P < .001), they did not significantly improve for the isolated SLAP-R group (P values ranging .635 to .123). The BT and SLAP-R+BT groups showed significant improvement in return to sport pre- to postoperatively whereas the SLAP-R group did not. The SLAP-R+BT group had the most patients reaching minimal clinical important difference, substantial clinical benefit, and patient acceptable symptom state American Shoulder and Elbow Society Score scores; however, this was not statistically significant.

Conclusions

SLAP II-IV lesions treated with BT or both SLAP-R+BT demonstrated improved outcomes compared with isolated SLAP-R at minimum 2-year follow-up. Concomitant biceps tenodesis should be considered when performing repair of SLAP II-IV tears.

Repair versus biceps tenodesis for the slap tears: A systematic review

PURPOSE

The ideal treatment algorithm is still controversial for Superior Labral Anterior-Posterior (SLAP) tears. In this systematic review, we aimed to clarify and ascertain which treatment modality is effective and more usable in which conditions.

METHODS

In this systematic review, we used the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines established for systematic reviews and meta-analysis. "SLAP or Superior Labral Anterior-Posterior" and "biceps tenodesis" search terms were used in The Cochrane Library database and Pubmed from their inception to the 30th of September 2020. A total of 2326 titles were screened and 2069 articles were removed because of their ineligibility. Full texts of 14 studies were screened and finally, six were suitable for the present systematic review. Demographic details and study characteristics, patient satisfaction, functional outcomes, return to preinjury sports level, reoperation, stiffness, sling time and rehabilitation protocols were reviewed and compared between SLAP repair and biceps tenodesis groups.

RESULTS

A total of 2326 titles were screened and six studies were detected eligible. Results of 287 patients (SLAP repair: 160, Biceps Tenodesis: 127) were reviewed in included six studies. Biceps tenodesis was showed as more satisfied technique in four of the studies but the statistical comparing results of two groups were not significantly different in each study. Different functional scoring systems used in the studies were not statistically significantly different between the groups. The percentage of return to sport and preinjury level is higher in biceps tenodesis in the five studies. The total reoperation rate for SLAP repair was 19/160 (12%) and biceps tenodesis was 7/127 (6%).

CONCLUSION

The biceps tenodesis has a higher return to preinjury sports level, higher patient satisfaction and lower reoperation rates but functional scores are similar between SLAP repair groups in patients with SLAP tear.

Posterior repair of isolated type 2 superior labrum anterior-posterior lesion prevents external rotation deficiency: long-term outcome study

PURPOSE

This study aimed to evaluate the outcomes of arthroscopic type 2 superior labrum anterior-posterior (SLAP) lesion repair in the general population and compare clinical outcomes according to patient age and repair site.

METHODS

Between 2005 and 2018, patients who underwent arthroscopic repair for isolated type 2 SLAP lesions were retrospectively reviewed. Baseline characteristics, pre- and postoperative [1-year and > 2-year (final)] shoulder range-of-motion, and functional scores, comprising the pain visual analogue scale (PVAS), functional VAS, and American Shoulder and Elbow Surgeons (ASES) score, were evaluated. Return to overhead activities and subjective satisfaction were assessed at the final follow-up, and patients were divided by age [group YB (< 40 years] and group OB (≥ 40 years)] and repair site [group P (only posterior labrum repair) and group AP (anterior and posterior labrum repair)]. Overall patient outcomes were analysed and compared between groups.

RESULTS

This study included 54 patients (45 men) with a mean age of 37.1 ± 8.3 years. The mean follow-up was 90.8 ± 51.3 months. Two patients experienced early failure, and one patient had a ruptured biceps tendon during the follow-up period. Final functional scores improved compared to their preoperative scores in all patients, except three (all p < 0.001). Fifty patients (98.0%) were satisfied, and 39 patients (76.5%) were able to perform overhead sports without restriction. In 25 patients who attended more than 7 years of follow-up (mean, 11.3 ± 2.7 years), 21 patients (84%) had an ASES score ≥ 80, and all patients had PVAS ≤ 2. There was no significant difference in clinical outcomes between groups YB and OB. The final median external rotation was significantly more restricted in group AP than in group P (40 [25-65] vs. 60 [50-70], p = 0.002).

CONCLUSION

Arthroscopic type 2 SLAP repair induced good short- and long-term clinical outcomes, return to overhead activities, and subjective satisfaction in the general population, regardless of age, due to the careful evaluation of patient history, physical examination, and imaging studies. However, performing only posterior repair seems sufficient since anterior labral SLAP lesion repair can limit ER. Isolated type 2 SLAP lesion posterior repair only is, thus, recommended to reduce external rotation deficit risk and increase satisfaction, regardless of patient age.

Predicting Patient Satisfaction With Maximal Outcome Improvement After Biceps Tenodesis

The goal of this study was to determine the threshold for achieving maximal outcome improvement (MOI) on the American Shoulder and Elbow Surgeons (ASES), Single Assessment Numeric Evaluation (SANE), and Constant-Murley (CM) questionnaires that predict satisfaction after isolated biceps tenodesis without concomitant rotator cuff repair. A retrospective analysis of prospectively collected data was performed for patients undergoing isolated biceps tenodesis from 2014 to 2017 at a single institution with minimum 6-month follow-up. Receiver operating characteristic curve analysis was used to determine thresholds for MOI for the ASES, SANE, and CM questionnaires. Stepwise multivariate logistical regression analysis was performed to identify predictors for achieving the threshold for MOI. A total of 123 patients were included in the final analysis. Receiver operating characteristic analysis determined that achieving 43.1%, 62.1%, and 61.4% MOI was the threshold for satisfaction for the ASES, SANE, and CM questionnaires, respectively. Regression analysis showed that concomitant superior labrum anterior-posterior (SLAP) repair was predictive of achieving MOI on the ASES and SANE questionnaires, whereas partial rotator cuff tear was predictive of achieving MOI on the CM questionnaire (P<.05 for both). Further, workers' compensation status, diabetes, history of ipsilateral shoulder surgery, and hypertension were negative predictors of achieving MOI on the SANE and CM questionnaires (P<.05 for all). Achieving MOI of 43.1%, 62.1%, and 61.4% is the threshold for satisfaction after biceps tenodesis for the ASES, SANE, and CM questionnaires, respectively. Concomitant SLAP repair was positively predictive of achieving MOI, whereas workers' compensation status, diabetes, history of ipsilateral shoulder surgery, and hypertension were negative predictors.

Type V superior labral anterior-posterior tears results in lower rates of return to play

PURPOSE

The purpose of this study was to evaluate the rate of return to play (RTP) in patients who underwent Type V superior labrum anterior-posterior (SLAP) repair compared to patients who underwent isolated Bankart repair in the setting of traumatic anterior shoulder instability.

METHODS

A retrospective review of patients who underwent arthroscopic Bankart repair and SLAP repair by a single surgeon between 2012 and 2017 was performed. Additionally, these were pair-matched in a 1:2 ratio for age, sex, sport and level of pre-operative play, with those undergoing isolated arthroscopic Bankart repair alone as a control group. RTP, level of RTP and the timing of RTP were assessed.

RESULTS

The study included a total of 96 patients, with 32 in the study group and 64 in the control group, and a mean follow-up of 59 months. Overall, there was no significant difference in the overall rate of return to play (26/32 (81.3%) vs 56/64 (87.5%), n.s), but there was a significantly higher rate of RTP at the same/higher level in the control group (14/32 (43.6%) vs 43/64 (67.2%), p = 0.0463). There was no significant difference in timing of RTP between the groups (n.s). There was no significant difference in recurrent instability (6/32 (18.8%) vs 5/64 (7.8%), n.s) but there was a significant difference in revision rates (5/32 (15.6%) vs. 2/64 (3.1%), p = 0.0392) between the Type V SLAP repair group and the control group.

CONCLUSION

Following arthroscopic repair, patients with Type V SLAP tears had a similar overall rate of RTP when compared directly to a control group of patients who underwent arthroscopic Bankart repair alone. However, those who underwent Type V SLAP repair reported significantly lower rates of RTP at the same or higher level compared to the control group.

Knotted Versus Knotless Anchors for Labral Repair in the Shoulder: A Systematic Review

PURPOSE

To compare biomechanical and clinical outcomes between knotless and knotted anchors in arthroscopic labral repair, specifically in (1) Bankart repair, (2) SLAP repair, (3) posterior labral repair, and (4) remplissage augmentation of Bankart repair.

METHODS

MEDLINE, EMBASE, and the Cochrane Library were searched according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines to find biomechanical and clinical studies comparing knotted and knotless anchors using the search term "knotless anchor."

RESULTS

Overall, 17 studies met inclusion criteria. There were 7 studies evaluating the biomechanical outcomes, of which 5 found mixed results between knotted and knotless anchors for arthroscopic Bankart repair, 1 demonstrated a difference for SLAP repair favoring knotless anchors, and 2 showed no significant difference for Remplissage in terms of ultimate load-to-failure. Four studies evaluated knotless labral anchors compared with knotted anchors in patients undergoing arthroscopic Bankart repair with no significant differences in outcomes reported between the 2 anchor types, except in one study that found an improved visual analog scale score and a lower recurrence and revision rate with knotted anchors. Five studies evaluated knotless anchors compared with knotted anchors in patients undergoing SLAP repair, and none of the included studies found any significant differences in the patient reported outcome measures or revision rates. Of the 5 studies comparing operative time, 4 found a reduced time with knotless anchors.

CONCLUSIONS

The clinical results show no significant differences in outcomes between knotless and knotted anchors for labral repair in the shoulder, including Bankart repair, SLAP repair, and posterior labral repair. However, there was conflicting evidence supporting knotless or knotted anchors in the biomechanical studies. However, operative times may be reduced with the use of knotless anchors.

SLAP tears and return to sport and work: current concepts

Superior labrum, anterior and posterior (SLAP) lesions are common and identified in up to 26% of shoulder arthroscopies, with the greatest risk factor appearing to be overhead sporting activities. Symptomatic patients are treated with physical therapy and activity modification. However, after the failure of non-operative measures or when activity modification is precluded by athletic demands, SLAP tears have been managed with debridement, repair, biceps tenodesis or biceps tenotomy. Recently, there have been noticeable trends in the operative management of SLAP lesions with older patients receiving biceps tenodesis and younger patients undergoing SLAP repair, largely with suture anchors. For overhead athletes, particularly baseball players, SLAP lesions remain a difficult pathology to manage secondary to concomitant pathologies and unpredictable rates of return to play. As a consequence, the most appropriate surgical option in elite throwers is controversial. The objective of this current concepts review is to discuss the anatomy, mechanism of injury, presentation, diagnosis and treatment options of SLAP lesions and to present current literature on outcomes affecting return to sport and work.

Cost Comparison of Open and Arthroscopic Treatment Options for SLAP Tears

Purpose

To identify cost drivers of open biceps tenodesis, arthroscopic biceps tenodesis, and arthroscopic SLAP repair in the setting of isolated SLAP tears and to perform a direct cost comparison between the procedures.

Methods

The 2014 State Ambulatory Surgery and Services Databases from 6 US states were used. Cases with Current Procedural Terminology codes 23430 (tenodesis of long tendon of biceps), 29807 (shoulder arthroscopy, repair of SLAP lesion), and 29828 (shoulder arthroscopy, biceps tenodesis) were selected, excluding patients who were >50 years old or had a concomitant rotator cuff repair. Generalized linear models were used to model costs based on surgical and patient variables.

Results

The mean patient age was 41.8 years for open biceps tenodesis, 31.6 for arthroscopic SLAP repair, and 41.3 for arthroscopic biceps tenodesis (P < .001). Open biceps tenodesis had cost reductions of $5,664 over arthroscopic biceps tenodesis (P = .001) and $2,320 over arthroscopic SLAP repair (P = .043). Male sex was associated with $3,798 more in costs (P < .001), presence of ≥1 comorbidities added $1,829 (P = .002), and each minute in the operating room added $37 (P < .001). Operative time for open biceps tenodesis averaged 114 minutes, and both arthroscopic procedures averaged 94 minutes (P < .001). Low-volume facilities were associated with $5,536 higher costs for arthroscopic biceps tenodesis (P = .001).

Conclusion

In patients aged ≤50 years with isolated SLAP tears, open biceps tenodesis provides cost savings over arthroscopic methods of treatment. There was no significant cost difference between arthroscopic SLAP repairs and arthroscopic biceps tenodesis. Given the increased emphasis on cost containment, surgeons should be aware of the procedural costs associated with the treatment of SLAP tears.

The majority of patients return to athletic activity following biceps tenodesis

PURPOSE

Biceps tenodesis is widely used as a primary treatment for long head of the biceps brachii pathology and superior labral anterior and posterior (SLAP) lesions. However, rates and timing of full return to sports (RTSs)/duty have not been systematically analysed. This systematic review examines the literature to ascertain the rate and timing of return to athletic activity, and the availability of specific criteria for safe return to atheletic activity following the biceps tenodesis.

METHODS

Based on PRISMA guidelines, this systematic review utilised the EMBASE, MEDLINE, and The Cochrane Library Databases. Eligible for inclusion were clinical studies reporting on return to athletic activity following biceps tenodesis. Statistical analysis was performed using SPSS.

RESULTS

This review identified 17 studies including 374 cases meeting the inclusion criteria. The majority of patients were men 260 (69.7%), with an median age of 42.2 years (range 16-88) and a mean follow-up of 37.4 months. The overall rate of RTS was 217/269 (80.7%), with 43/59 (72.9%) returning to the same level. In overhead athletes, the overall rate of return to play was 39/49 (79.6%). Among military personnel, the overall rate of return to duty was 61/74 (82.4%). The average time to RTS was 5.4 (range 3-11) months. 10 (58.8%) Studies reported a recommended time window within which patients were allowed to return to full activity. Specific criteria for return to play were not reported in any of the identified studies.

CONCLUSION

While overall rate of return to athletic activity was reportedly high following biceps tenodesis, one in four patients were not able to resume athletic activity at the same level. At present, there is no objective assessment of when patients can return to full activity reported in the literature.

Validation of a Practical Forearm Supination Strength Measurement Technique in the Large Sample Cohort

INTRODUCTION

The strength of forearm in pronation and supination (P/S) is an important clinical assessment during pre-operative examination as well as in post-operative evaluation. Many clinical trials concerning the measurement of forearm P/S strength were performed using a dynamometer fixed on the wall. The aim of this study was to bring out a simple and reliable technique for the measurement of P/S strength using a dynamometer manually supported and stabilized by an examiner. We hypothesized that there are no differences in evaluation of elbow P/S strength using the dynamometer fixed or the dynamometer stabilized by an operator in healthy people.

METHODS

The study was performed on a cross-sectional cohort of 100 healthy subjects without any history of injuries or previous surgery of the upper limbs. Isometric forearm P/S strengths were measured on the dominant and non-dominant forearms, using the dynamometer fixed on a table, and using the same dynamometer kept by an operator. The measurements were repeated in triplicate at 45°, 90° and 120° of elbow flexion in both upper limbs for all patients.

RESULTS

A total of 100 subjects (50 females, 50 males) were included in the study group. The mean age was 46.5 years (range 25-52 years). Female and male subjects showed no significant differences concerning the mean age (F/M ratio 0.50/0.50). The mean body mass index of all participants was 24.34 ± 3.66 kg/m2.No significant statistics difference was reported between the P/S strength measured using the two detection methods in our study group (45°, 90° and 120° of elbow flexion and both upper limbs).

CONCLUSION

The manually stabilized technique is a valid and reliable technique to assess the P/S strength of the forearm. This is a simple and effective method that may be reproduced in our daily clinical practice as well as in sportive practice.

Return to Play after Arthroscopic Bankart Repair Combined with Open Subpectoral Biceps Tenodesis

Purpose

To evaluate the clinical outcomes and rate of return to play (RTP) in patients who underwent arthroscopic Bankart repair and open subpectoral biceps tenodesis.

Methods

A retrospective review of patients who underwent combined arthroscopic Bankart repair and open subpectoral biceps tenodesis by a single surgeon between 2012 and 2016 was performed. RTP, the level of return, and the timing of return were assessed. Visual analog scale for pain, Rowe score, Shoulder Instability-Return to Sport after Injury score, and Subjective Shoulder Value were evaluated.

Results

The study included 14 patients, with a mean follow-up of 34.2 ± 12.1 months. Of the 14 patients, 13 (92.9%) returned to sport at a mean of 4.8 ± 1.2 months and 9 (64.3%) returned to the same or higher level of sport. At final follow-up, the mean Rowe was 80.0 ± 16.3, the mean Subjective Shoulder Value was 81.0 ± 15.1, the mean Shoulder Instability-Return to Sport after Injury was 57.3 ± 25.6, and the mean visual analog scale score was 2.6 ± 1.5. One patient had a recurrent dislocation, whereas no patients underwent a further operation on the ipsilateral shoulder.

Conclusion

Patients undergoing arthroscopic Bankart repair combined with open subpectoral biceps tenodesis had a high rate of RTP with a low rate of recurrent instability.

Superior Labral Anterior Posterior Repair and Biceps Tenodesis Surgery: Trends of the American Board of Orthopaedic Surgery Database

BACKGROUND

Recent evidence has specified indications for performing superior labral anterior posterior (SLAP) repair and biceps tenodesis (BT) for the treatment of bicipital-labral lesions in the shoulder. Trends in performance of these procedures are expected to reflect the growing body of research regarding this topic.

PURPOSE

To report practice trends for the surgical treatment of SLAP lesions utilizing the American Board of Orthopaedic Surgery (ABOS) database, particularly in older patients.

STUDY DESIGN

Cohort study; Level of evidence, 3.

METHODS

The ABOS database was retrospectively queried between 2012 and 2017 by Current Procedural Terminology (CPT) codes for SLAP repair (29807), open BT (23430), and arthroscopic BT (29828). The patient population was excluded if any concomitant open shoulder procedure was performed. Trends over time were evaluated with respect to case volume, patient age, surgeon subspecialty, and whether a concomitant arthroscopic rotator cuff repair (RCR) was performed (CPT 29827).

RESULTS

A total of 9908 cases met inclusion/exclusion criteria: 4632 performed with RCR and 5276 performed without. The mean age of patients without RCR was 40.8 ± 13.8 years, while for those receiving RCR it was 55.0 ± 9.9 years (P < .001). In patients without RCR, there was a significant decline in rate of SLAP repairs performed over this period (P < .001). A significantly greater proportion of patients receiving open and arthroscopic BT were older than 35 years of age, compared with those receiving SLAP repair (P < .001). Within the RCR cohort, there was also a significant decline in concomitant SLAP repairs performed (P < .001) over the study period. With respect to BT, open BT was performed more frequently in the cohort without RCR (74.5%) than in the cohort with RCR (52.1%) (P < .001). Similarly, arthroscopic BT was performed more commonly in the cohort with RCR (47.9%) than in the cohort without RCR (25.5%) (P < .001).

CONCLUSION

The ABOS database revealed significantly reduced rates of SLAP repairs performed in recent times. Trends with age remained consistent over time, in that SLAP repairs were predominantly performed in younger patients. Open BT was performed more frequently overall, but with an increased proportion of arthroscopic BT occurring with RCR. Arthroscopic BT was performed much more frequently with RCR than without.

Rates of Subsequent Shoulder Surgery Within Three Years for Patients Undergoing SLAP Repair Versus Biceps Tenodesis

Purpose

To investigate the demographics of patients for whom SLAP repair or biceps tenodesis was performed, as well as to compare rates of additional shoulder surgery for these 2 procedures within 3 years postoperatively.

Methods

Using the MarketScan Commercial Database, we examined all patients with SLAP tear who underwent arthroscopic SLAP repair or open or arthroscopic biceps tenodesis within the encompassed time period (2003-2014). Rates of repeat shoulder surgery within 3 years were evaluated, as were comparative demographics.

Results

In total, 25,142 patients initially underwent SLAP repair, of whom 11.5% had subsequent shoulder surgery within 3 years. A total of 840 patients initially underwent biceps tenodesis as treatment for a SLAP tear, of whom 13.0% underwent additional shoulder surgery within 3 years. Rates of subsequent shoulder surgery between the 2 procedural groups did not statistically differ (P = .19). Patients who underwent SLAP repair were younger than those who underwent tenodesis (mean age 38.3 vs 49.3 years, P < .01). For patients requiring additional surgery, the SLAP repair group had a greater representation of those ≥35 years old, whereas the tenodesis group had a greater representation of those <35 years old (P < .01). Male patients experienced an increase in rate of subsequent shoulder surgery when initially undergoing tenodesis versus SLAP repair (13.3% vs 11.1%, P < .01).

Conclusions

The rates of additional shoulder surgery for patients undergoing SLAP repair and biceps tenodesis were similar within 3 years of the index procedure. Patients who underwent SLAP repair were younger than those who underwent tenodesis. Of those requiring additional surgery, patients initially treated with SLAP repair were older (≥35 years) and those treated with tenodesis were younger (<35 years). Male patients experienced an increase in rate of subsequent shoulder surgery when initially treated with tenodesis versus SLAP repair.

Outcomes of Primary Biceps Subpectoral Tenodesis in an Active Population: A Prospective Evaluation of 101 Patients

PURPOSE

To evaluate the surgical outcomes of a primary subpectoral biceps tenodesis for long head of the biceps tendon (LHBT) pathology in a large cohort of prospectively, serially collected, patients in a young active population that has known high physical demands and requirements of their shoulder to perform their vocation.

METHODS

A retrospective review of prospectively collected data from an active military personnel with a diagnosis of a Type II SLAP tear or biceps tenosynovitis was performed. Outcomes were evaluated at a minimum follow-up time of 18 months based on preoperative and postoperative assessments of the Single Assessment Numeric Evaluation, Western Ontario Rotator Cuff index, biceps position, and return to active duty. Inclusion criteria were (1) SLAP tears on magnetic resonance arthrogram (classified into SLAP group), and (2) no SLAP tear but examination findings of biceps tendonitis (placed in the LHBT tendonitis group). Patients were excluded for full-thickness rotator cuff tears, high-grade partial thickness tears requiring repair, acromioclavicular joint pathology, and labral pathology outside of the SLAP lesion. Patients from both groups subsequently were treated with open, subpectoral tenodesis.

RESULTS

Over a 6-year period at a mean follow-up of 2.75 years (range 1.5-5.7 years), 125 active-duty military personnel with mean age of 42.6 years (range 26.3-56.5) were enrolled. A total of 101 of 125 patients (81%) completed study requirements at a mean of 2.75 years (range 1.5-5.7 years). In total, 40 patients were diagnosed with type II SLAP tears (39.6%) and 61 with biceps tendonitis without SLAP tear (60.4%). Following open, subpectoral tenodesis, there was a significant improvement in patient outcomes (Western Ontario Rotator Cuff = 54% preoperative vs 89% postoperative, Single Assessment Numeric Evaluation = 58 preoperative vs 89.5 postoperative, P < .01). In total, 82% of patients returned to full activity at a mean of 4.1 months. The biceps muscle measured relative to the antecubital fossa of operative (mean 3.20 cm) versus nonoperative (3.11 cm) was not clinically different (P = .57). There was an 8% complication rate, including 3 requiring revision, 2 superficial infections, and 3 transient neurapraxias.

CONCLUSIONS

Primary subpectoral open biceps tenodesis for SLAP tears or pathology of the LHBT provides significant improvement in shoulder outcomes with a reliable return to activity level with low risk for complications.

Labral Repair Versus Biceps Tenodesis for Primary Surgical Management of Type II Superior Labrum Anterior to Posterior Tears: A Systematic Review

PURPOSE

To examine the outcomes of SLAP repair versus biceps tenodesis (BT) for the index treatment of isolated type II SLAP tears.

METHODS

A search of PubMed, MEDLINE, and EMBASE was performed in April 2018 for English-language studies that presented outcomes data on patients with isolated type II SLAP tears treated with either SLAP repair or BT at the primary surgical time point.

RESULTS

Twenty-three studies (i.e., 2 randomized control trials, 7 retrospective cohort, 3 prospective cohort, 4 case-control, and 7 case series) were included. Isolated type II SLAP tears were treated via SLAP repair in 781 patients with a mean age of 35 years (range, 22-58 years) and a mean postoperative follow-up of 35 months (range, 3-63 months). BT was performed in 100 patients with a mean age of 44 years (range, 18-64 years) and a mean postoperative follow-up of 32 months (range, 24-75 months). Similar postoperative scores were noted in both the SLAP repair and BT groups for American Shoulder and Elbow Surgeons, Constant, University of California, Los Angeles, and visual analog scale pain scores. The rate of return to sports was 20% to 95% for SLAP repair and 73% to 100% for BT. Reoperation rates for SLAP repair and BT were 2.9% to 40% and 0% to 15.3%, respectively.

CONCLUSIONS

This study suggests that SLAP repair and BT are both acceptable as index treatment for isolated type II SLAP tears. SLAP repair remains the most commonly performed index procedure; however, BT appears equally efficacious and may represent an attractive alternative.

Editorial Commentary: Which to Fix-the Biceps or the Labrum? The Shoulder SLAP Tear Is Still Controversial

A type II SLAP tear in a young and active patient remains a controversial and challenging clinical entity. Arthroscopic repair is generally a successful procedure for type II SLAP lesions, but the results can be unpredictable. Biceps tenodesis has become increasingly popular for the management of these lesions, with recent clinical literature suggesting that the results may be equivalent or superior to those of SLAP repair. Recent meta-analyses have summarized the available clinical data and offered some guidance on which patients may benefit most from either procedure.

Predictive Factors and the Duration to Pre-Injury Work Status Following Biceps Tenodesis

PURPOSE

To determine when patients return to work after biceps tenodesis stratified by the preinjury level of work-intensity and to identify predictive measures of return to work.

METHODS

Patients undergoing biceps tenodesis between 2014 and 2017 were reviewed. Patients receiving concomitant rotator cuff repair or arthroplasty, revision biceps tenodesis, or unemployment before the procedure were excluded. Patient-acceptable symptom state (PASS), substantial clinical benefit, and minimal clinically important difference were calculated for the American Shoulder Elbow Society (ASES) score, subjective Constant-Murley score (CMS), and Single Assessment Numerical Evaluation (SANE) using the anchor-based and distribution-based approach. Preoperative outcome scores were analyzed to determine their predictive power of return to work using receiver operator curve area under the curve (AUC) analysis. Multivariate logistical analysis assessed predictive variables of return to work.

RESULTS

Seventy-nine percent of patients were able to return to work without permanent restrictions at an average of 5.4 ± 2.8 months after biceps tenodesis. Return to work status for sedentary, light, moderate, and heavy duties were 100%, 85%, 71%, and 69%, respectively. Return to work was associated with achieving PASS for the ASES and SANE questionnaires (P = .006, .003, respectively) but not for the CMS (P = .768). On multivariate analysis, there were no preoperative or intraoperative variables that were predictive of return to work in full capacity. The preoperative Short Form-12 mental component score (>59.4, AUC = 71.2%) was predictive of returning to work.

CONCLUSIONS

After biceps tenodesis, most patients were able to return to work at an average of 5.4 ± 2.8 months. Furthermore, there were no demographic or intraoperative variables that were predictive of return to work. Work intensity was not correlated with an increased duration of return to work. Achieving PASS on the ASES and SANE questionnaires was predictive of return to work.

Trends in the Management of Isolated SLAP Tears in the United States

Background:

The management of superior labrum anterior and posterior (SLAP) tears remains controversial, with surgical treatment options including SLAP repair, debridement, and open or arthroscopic biceps tenodesis (BT), based on patient factors and the type of tear.

Hypothesis:

We hypothesized that SLAP repair has become less frequently performed over time, while BT is more frequently performed, particularly in patients ≥ 40 years.

Study Design:

Descriptive epidemiology study.

Methods:

A retrospective query was performed using the Humana insurance database from years 2007 to 2016. For the management of a SLAP tear diagnosis (International Classification of Diseases–Ninth Edition [ICD-9] code: 840.7), independent and exclusive cohorts were formed using Current Procedural Terminology (CPT) codes for debridement (29822, 29823), SLAP repair (29807), open or arthroscopic BT (29828, 23430), and SLAP repair combined with BT (29828 OR 23430 AND 29807).

Results:

Of 46,650 diagnoses of a SLAP tear, there were 3347 patients who underwent operative management for an isolated SLAP tear from 2007 to 2016. There was a linear increase of SLAP tear diagnoses per year (r² = 0.800, P < .001) during this period. Overall, SLAP repair was performed in 1629 patients (48.7%), debridement was performed in 1076 patients (32.1%), BT was performed in 552 patients (16.5%), and combined SLAP repair and BT was performed in 90 patients (2.7%). There was a 69.3% decrease in isolated SLAP repair from 2007 to 2016 (r² = 0.882, P < .001). BT for the diagnosis of an isolated SLAP tear increased by 370.0% over the same period (r² = 0.800, P < .001). SLAP repair had an equivalent percentage of being performed in patients both older and younger than 40 years (P = .218). There was a 1500.0% increase in BT performed in patients older than 40 years during the study period. There were no statistical differences in the postoperative incidence of stiffness, surgical site infections, and reoperations between all surgical treatment groups (P > .05).

Conclusion:

An analysis of a large private-payer database revealed that surgical treatment of isolated SLAP tears in the United States has shifted from 2007 to 2016, with an increase in the frequency of BT and a decline in the frequency of SLAP repair, particularly in patients older than 40 years.
