Background:
Active-duty servicemembers are a population at risk for the development of posterior shoulder instability. While short-term outcomes after arthroscopic posterior labral repair for ...posterior shoulder instability are promising, there is a paucity of longer term follow-up data for this procedure.
Purposes:
The primary purpose was to report midterm outcomes after arthroscopic posterior labral repair in active-duty military patients for posterior shoulder instability without bone loss. The secondary purpose was to determine if outcomes varied between anchor types used.
Study Design:
Cohort study; Level of evidence, 3.
Methods:
Preoperative and postoperative outcomes, with a minimum 3-year follow-up, for a visual analog scale for pain, the Single Assessment Numeric Evaluation (SANE), the American Shoulder and Elbow Surgeons (ASES) score, and the Rowe score were collected and analyzed. A separate subgroup analysis was performed comparing the outcomes of patients who underwent repair with biocomposite anchors versus those who underwent repair with all-suture anchors.
Results:
A total of 73 patients with a mean follow-up of 82.55 ± 24.20 months met the inclusion criteria and were available for analysis. As a whole, the cohort demonstrated statistically and clinically significant improvements in outcome scores at final follow-up. Preoperative and postoperative range of motion did not vary significantly. While the difference in final outcome scores between the 2 anchor types did not reach statistical significance, a statistically significantly larger proportion of patients who underwent repair with all-suture anchors versus those who underwent repair with biocomposite anchors met the Patient Acceptable Symptom State for the SANE (97.14% vs 78.95%, respectively; P = .0180) and the ASES score (88.57% vs 68.42%, respectively; P = .0171). The proportion of patients who achieved the substantial clinical benefit or surpassed the minimal clinically important difference, however, did not vary by anchor type. Overall, 70 patients (95.89%) remained on active duty and were able to return to preinjury work and recreational activity levels. There were 3 patients (4.11%) who had recurrent posterior instability.
Conclusion:
This population of active-duty servicemembers undergoing posterior labral repair for posterior labral instability without bone loss demonstrated a statistically and clinically significant improvement in midterm outcomes, a low recurrence rate, and a rate of return to active duty of 95.89%, regardless of the anchor type used.
Background:
There is a high prevalence of combined shoulder instability in military patients. Short-term outcomes after 270° labral repair are promising; however, there is a paucity of longer term ...outcome data in this high-demand group of patients.
Purpose:
To report the midterm outcomes of active-duty military patients treated with 270° labral repair for combined shoulder instability.
Study Design:
Case series; Level of evidence, 4.
Methods:
All consecutive patients between January 2011 and January 2019 who underwent 270° labral repair by the senior surgeon with complete outcome scores were identified. All patients had experienced a shoulder dislocation after a traumatic event and had magnetic resonance imaging and intraoperative findings consistent with combined-type instability. A total of 52 patients met the inclusion criteria for the study, and all were active-duty servicemembers at the time of surgery.
Results:
The mean follow-up was 78.21 months (range, 24-117 months). There was a statistically significant increase in the mean American Shoulder and Elbow Surgeons score (from 44.92 to 89.31; P < .0001), Single Assessment Numeric Evaluation score (from 52.32 to 93.17; P < .0001), and Rowe instability score (from 46.63 to 91.35; P < .0001) from preoperatively to postoperatively. Mean pain decreased significantly as measured by the visual analog scale for pain (from 8.04 to 1.44; P < .0001). Range of motion in forward flexion (from 155.29° to 155.96°; P = .6793), external rotation (from 67.50° to 65.29°; P = .0623), and internal rotation (from T9.58 to T9.56; P = .9650) did not change significantly postoperatively. Outcomes did not differ significantly for patients who underwent surgery on their dominant shoulder versus those who underwent surgery on their nondominant shoulder, nor did outcomes vary with the type of anchor utilized (biocomposite vs all-suture). The overall rate of return to active duty was 92.31%.
Conclusion:
Midterm outcomes in this population of active-duty patients undergoing 270° labral repair for combined shoulder instability demonstrated a statistically and clinically significant improvement in patient-reported outcome scores, a significant decrease in pain, and an overall rate of return to active duty of 92.31%.
Background:
Biceps tenodesis has been suggested as a superior surgical technique compared with isolated labral repair for superior labral anterior-posterior (SLAP) tears in patients older than 35 ...years. The superiority of this procedure in younger patients, however, is yet to be determined.
Purpose:
To compare the outcomes of arthroscopic SLAP repair with those of arthroscopic-assisted subpectoral biceps tenodesis for type II SLAP tears in active-duty military patients younger than 35 years.
Study Design:
Cohort study; Level of evidence, 3.
Methods:
Preoperative and postoperative evaluations with a minimum 5-year follow-up including the visual analog scale (VAS), the Single Assessment Numeric Evaluation (SANE), and the American Shoulder and Elbow Surgeons (ASES) shoulder score were administered, and scores were compared between 2 groups of patients younger than 35 years. One group included 25 patients who underwent SLAP repair, and the second group included 23 patients who underwent arthroscopic-assisted subpectoral biceps tenodesis.
Results:
The preoperative patient age (P = .3639), forward flexion (P = .8214), external rotation (P = .5134), VAS pain score (P = .4487), SANE score (P = .6614), and ASES score (P = .6519) did not vary significantly between the 2 study groups. Both groups demonstrated statistically significant increases in function as measured by the ASES and SANE and decreases in pain as measured by the VAS at a minimum of 5 years postoperatively. Also at a minimum of 5 years postoperatively, patients in the tenodesis group had lower pain (1.3 vs 2.6, respectively; P = .0358) and higher SANE (84.0 vs 63.3, respectively; P = .0001) and ASES (85.7 vs 75.4, respectively; P = .0342) scores compared with those in the repair group. Failure rate was 20.0% in the repair group versus 0.0% in the tenodesis group (P = .0234).
Conclusion:
Active-duty military patients younger than 35 years with type II SLAP tears had more predictable improvement in pain, better functional outcomes, and lower failure rates after biceps tenodesis compared with SLAP repair for type II SLAP tears. Overall, the results of this study indicate that arthroscopic- assisted subpectoral biceps tenodesis is superior to arthroscopic SLAP repair for the treatment of type II SLAP tears in 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.
Background:
Arthroscopic rotator cuff repair is an effective procedure through which to decrease pain and increase strength, with favorable long-term outcomes demonstrated in older patient ...populations with full-thickness rotator cuff tears. The long-term outcomes after this procedure in younger, higher-demand patients, however, is not as clearly defined.
Purpose:
To report on the long-term outcomes after arthroscopic rotator cuff repair of traumatic full-thickness rotator cuff tears in active duty military patients under the age of 40 years at the time of surgery.
Study Design:
Case series; Level of evidence, 4.
Methods:
Preoperative, midterm, and final evaluations were collected, including scores on the visual analog scale for pain, Single Assessment Numeric Evaluation, and American Shoulder and Elbow Surgeons shoulder form. A total of 42 patients were screened for inclusion: 3 underwent additional surgical procedures on the operative shoulder and 2 were lost to follow-up, leaving 37 patients with mean follow-up of 104.51 months available for analysis. A subgroup analysis was performed comparing outcomes between patients with Southern California Orthopaedic Institute grade 1 or 2 tears and those with grade 3 or 4 tears.
Results:
At final follow-up, pain per the visual analog scale decreased to 1.16 from 8.03 (P < .0001); the Single Assessment Numeric Evaluation score increased to 87.32 from 48.24 (P < .0001); and the American Shoulder and Elbow Surgeons score increased to 88.68 from 41.00 (P < .0001). There was no statistically significant difference in outcome scores or range of motion between midterm and final follow-up. Improvement in outcome scores and range of motion at final follow-up did not vary between patients with small and large tears. Of 42 patients, 37 (88.1%) were able to return to full unrestricted active duty and sporting activity, while 5 (11.9%) were medically separated from the military.
Conclusion:
Active duty military patients under the age of 40 years with traumatic full-thickness rotator cuff tears had statistically and clinically significant increases in outcome scores and decreases in pain after arthroscopic rotator cuff repair at long-term follow-up.
Background:
Members of the military are known to experience disproportionately high rates of both glenohumeral instability and superior labrum anterior-posterior (SLAP) tears when compared with ...civilian populations. Although the outcomes after simultaneous repair of Bankart and SLAP lesions have been well described, there is a paucity of literature available regarding the operative management of posterior instability with concomitant superior labral pathology.
Purpose:
To compare outcomes of combined arthroscopic posterior labral and SLAP repair with those of isolated posterior labral repair.
Study Design:
Cohort study; Level of evidence, 3.
Methods:
All consecutive patients younger than 35 years who underwent arthroscopic posterior labral repair from January 2011 to December 2016 with a minimum follow-up of 5 years were identified. From this cohort of eligible patients, all individuals who had undergone combined SLAP and posterior labral repair (SLAP cohort) versus posterior labral repair alone (instability cohort) were then identified. Outcome measures including the visual analog scale score, Single Assessment Numeric Evaluation (SANE), American Shoulder and Elbow Surgeons (ASES) score, Rowe instability score, and range of motion were collected pre- and postoperatively and scores were compared between groups.
Results:
In total, 83 patients met the inclusion criteria for the study. All patients were active-duty military at the time of surgery. The mean follow-up was 93.79 ± 18.06 months in the instability group and 91.24 ± 18.02 months in the SLAP group (P = .5228). Preoperative SANE and ASES scores were significantly worse in the SLAP group. Both groups experienced statistically significant improvements in outcome scores postoperatively (P < .0001 for all), and there were no significant differences in any outcome scores or range of motion between groups. In total, 39 patients in the instability cohort and 37 in the SLAP cohort returned to preinjury levels of work (92.86% vs 90.24%, respectively; P = .7126), and 38 instability patients and 35 SLAP patients returned to preinjury levels of sporting activity (90.48% vs 85.37%, respectively; P = .5195). Two patients in the instability group and 4 patients in the SLAP group were medically discharged from the military (4.76% vs 9.76%; P = .4326), and 2 patients in each cohort had experienced treatment failure at the final follow-up (4.76% vs 4.88%; P > .9999).
Conclusion:
Combined posterior labral and SLAP repair led to statistically and clinically significant increases in outcome scores and high rates of return to active-duty military service that did not differ significantly from the results after isolated posterior labral repair. The results of this study indicate that simultaneous repair is a viable treatment option for the management of combined lesions in active-duty military patients <35 years of age.
Background:
Posterior instability has been reported to account for up to 24% of cases of shoulder instability in certain active populations. However, there is a paucity of data available regarding ...the risk factors associated with posterior glenoid bone loss.
Purpose:
To characterize the epidemiology of, and risk factors associated with, glenoid bone loss within a cohort of patients who underwent primary arthroscopic shoulder stabilization for isolated posterior-type glenohumeral instability.
Study Design:
Cross-sectional study; Level of evidence, 3.
Methods:
This was a retrospective analysis of patients who underwent primary arthroscopic shoulder stabilization for posterior-type instability between January 2011 and December 2019. Preoperative magnetic resonance arthrograms were used to calculate posterior glenoid bone loss using a perfect circle technique. Patient characteristics and revision rates were obtained. Bone loss (both in millimeters and as a percentage) was compared between patients based on sex, age, arm dominance, sports participation, time to surgery, glenoid version, history of trauma, and number of anchors used for labral repair.
Results:
Included were 112 patients with a mean age of 28.66 ± 10.07 years; 91 patients (81.25%) were found to have measurable bone loss. The mean bone loss was 2.46 ± 1.68 mm (8.98% ± 6.12%). Significantly greater bone loss was found in athletes versus nonathletes (10.09% ± 6.86 vs 7.44% ± 4.56; P = .0232), female versus male patients (11.17% ± 6.53 vs 8.17% ± 5.80; P = .0212), and patients dominant arm involvement versus nondominant arm involvement (10.26% ± 5.63 vs 7.07% ± 6.38; P = .0064). Multivariate regression analysis identified dominant arm involvement as an independent risk factor for bone loss (P = .0033), and dominant arm involvement (P = .0024) and athlete status (P = .0133) as risk factors for bone loss >13.5%. At the conclusion of the study period, 7 patients had experienced recurrent instability (6.25%).
Conclusion:
The findings of this study are in alignment with existing data suggesting that posterior glenoid bone loss is highly prevalent in patients undergoing primary arthroscopic stabilization for posterior-type shoulder instability. Our results suggest that patients with dominant arm involvement are at risk for greater posterior glenoid bone loss. Athlete status and dominant arm involvement were identified as independent risk factors for bone loss >13.5%.
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.
To report mid-term outcomes of active-duty patients with anterior shoulder instability following our technique for double-pulley remplissage (DPR) with concomitant anterior labral repair.
All ...consecutive patients from 1/2010 through 12/2016 that underwent DPR by the senior surgeon with complete outcome scores were identified. All patients had experienced a shoulder dislocation following a traumatic event, and had subsequent instability recalcitrant to conservative management. Patients were excluded if they were lost to follow-up (3) of if they underwent stabilization procedures other than DPR (148). Outcome measures were completed by patients within 1 week prior to surgery and at latest follow-up. Twenty-four patients met the inclusion criteria for the study, and all were active-duty military at the time of surgery.
20/24 (83.3%) patients met the patient acceptable symptomatic state (PASS), while 21/24 (87.5%) achieved substantial clinical benefit (SCB) and 22/24 (91.7%) exceeded the minimal clinically important difference (MCID) for their operative shoulder, as determined by the American Shoulder and Elbow Surgeons (ASES) Score. 21/24 (87.5%) patients met the PASS, while 19/24 (79.2%) achieved SCB and 20/24 (83.3%) exceeded the MCID for their operative shoulder, as determined by the single assessment numeric evaluation (SANE). In addition, 23/24 (95.8%) patients exceeded the MCID for their operative shoulder, as determined by the Rowe Instability score. Preoperative and postoperative range of motion did not vary significantly. All patients had decreased pain postoperatively (P < .0001); 22/24 (91.67%) of patients remained on active-duty status. Failure rate, defined as recurrent subluxation or dislocation, was 4.2%.
Mid-term outcomes in this population of active-duty patients undergoing DPR for shoulder instability without glenoid bone loss demonstrate a statistically and clinically significant improvement in patient-reported outcomes, a significant decrease of pain and an overall return to active-duty rate of 91.67%.
IV, therapeutic case series.
The purpose of this study is to investigate the outcomes of arthroscopic rotator cuff repair in a severely obese population (body mass index BMI > 0 kg/m2) compared to a healthy weight population ...(BMI 18.5-24.9 kg/m2).
This study is a retrospective review of prospectively collected data examining the outcomes of arthroscopic rotator cuff repair in both severely obese patients and healthy weight patients. Primary outcome measures analyzed include the American Shoulder and Elbow Surgeons (ASES) Score, the Single Assessment Numeric Evaluation (SANE), pain Visual Analog Scale (VAS), range of motion, and complications.
A total of 89 patients met inclusion/exclusion criteria: 52 healthy weight patients (BMI 18.5-24.9 kg/m2) and 37 severely obese patients (BMI >40 kg/m2). Patient-reported pain and functional outcomes had significantly improved after surgery in both groups with regard to the visual analog score (VAS) scores, Single Assessment Numeric Evaluation (SANE) scores, and American Shoulder and Elbow Surgeons Shoulder (ASES) scores (P < .0001). When directly comparing the outcomes in the healthy weight group to the severely obese group, the latter had significantly inferior outcomes in VAS scores (P = .0048), SANE scores (P = .0118), ASES scores (P = .0031), and postoperative internal rotation (P =.0132). At large, these outcomes did not have clinically significant differences. The severely obese group also had higher total numbers of comorbid conditions and longer operative times (P =.0041).
Severely obese patients and their associated comorbid conditions pose unique challenges in rotator cuff tear management, but they still achieve overall excellent outcomes after repair and noninferior clinical differences when compared to healthy weight patients.
Level III, retrospective comparative study.
