Purpose: To determine the prevalence of chronic trochanteric bursitis (TB) in patient being treated for femoroacetabular impingement (FAI) and determine the effectiveness of arthroscopic bursectomy and iliotibial band lengthening (AB-ITB-L) at the time of hip arthroscopy for FAI., Methods: Patients diagnosed with primary FAI and chronic TB were included in the study. Patients were included if they underwent hip arthroscopy with labral repair, femoral and/or acetabular osteoplasty, and AB-ITB-L. Patients were matched by age and gender to patients without chronic TB., Results: The prevalence of chronic TB with FAI was 7% (90/1,278). Females were 5.3 times more likely to have TB compared with males (95% confidence interval: 3.2-8.7). Patients more than 30 years of age were 2.5 times more likely to have TB (95% confidence interval: 1.48-4.4). Of the 90 patients diagnosed with TB, 72 (54 female, 18 male) with an average age of 36.7 years underwent AB-ITB-L at the time of their index hip arthroscopy for FAI. All 72 patients had associated intra-articular pathology consisting of a combined cam and pincer pathology. The TB (average follow-up = 42 ± 9.9 months) and non-TB group (average follow-up = 42 ± 9.1 months) both had significant improvement from preoperative to postoperative scores for Hip Outcome Score Activities Daily Living, Hip Outcome Score Sport, Modified Harris Hip Score, Western Ontario and McMaster Universities Arthritis Index, Short Form (SF)-12 Physical Component score, and SF-12 Mental Component Score. There was no significant difference between the 2 groups in postoperative patient reported outcome scores., Conclusions: The occurrence of chronic TB in the FAI population, which did not adequately respond to nonoperative management, for a single surgeon high volume hip arthroscopy practice was 7%, and was more commonly seen in women older than 30 years. Patients who undergo concomitant AB-ITB-L for chronic TB report excellent pain relief, and have equivalent results and outcome scores that are not inferior when compared with patients with primary FAI without chronic TB., Level of Evidence: Level III, retrospective matched case control study., (Copyright © 2017 Arthroscopy Association of North America.

Purpose: To conduct a systematic review of the literature comparing patient outcomes following arthroscopic and open operative management of iliopsoas tendonitis (IPT) following total hip replacement (THR)., Methods: This review study was conducted in accordance with the Preferred Reporting Items for Systematic review and Meta-Analysis (PRISMA) statement. Inclusion criteria were as follows: outcome studies following open or arthroscopic iliopsoas tendon release after THR with at least 6 months of follow-up, English language, and human studies. The exclusion criteria included case reports, articles evaluating nonsurgical management or cup revision, and articles without a specific diagnosis of IPT or in which results between open and arthroscopic treatment were reported in conjunction., Results: A total of 131 studies were initially retrieved, with 7 satisfying all inclusion criteria (4 studies on arthroscopic tenotomy and 3 studies on open tenotomy). The review included a total of 88 patients with IPT-61 patients treated arthroscopically and 27 patients treated with open tenotomy. In total, 77 of the 88 patients demonstrated successful outcomes following surgery. In the group treated with arthroscopy, 91.8% (56/61) of patients had successful outcomes, whereas in those treated with open tenotomy, 77.8% (21/27) of patients had successful outcomes. Of patients with signs of mechanical impingement from acetabular component overhang, those who underwent open tenotomy had complete pain relief in 6/8 patients (75%) compared to arthroscopic tenotomy in which there was relief in 40/43 patients (93%)., Conclusions: Arthroscopic iliopsoas release for management of IPT is suggested to be an effective minimally invasive operative technique that may also yield a lower complication rate in comparison to open tenotomy. Tenotomy, both arthroscopic and open, are successful treatment options for IPT, including those with signs of mechanical impingement, and are recommended prior to cup revision., Level of Evidence: Level IV, systematic review of level IV studies., (Copyright © 2017 Arthroscopy Association of North America.

Purpose: To investigate clinical outcomes after primary and revision arthroscopic treatment for snapping scapula syndrome (SSS) and identify predictive factors associated with outcomes., Methods: Patients who underwent arthroscopic treatment for SSS between October 2005 and December 2013 were identified in a prospectively collected database. The inclusion criteria were patients with a diagnosis of symptomatic SSS, in whom extensive nonoperative modalities failed, who underwent arthroscopic surgery for SSS, and who had undergone surgery a minimum of 2 years earlier. Postoperative clinical outcomes were assessed with the American Shoulder and Elbow Surgeons score; short version of the Disabilities of the Arm, Shoulder and Hand questionnaire; and general health Short Form 12 (SF-12) scores, including both physical component summary and mental component summary. Patient satisfaction was recorded on a 10-point visual analog scale. Scapular bony morphology was determined on preoperative magnetic resonance imaging., Results: Ninety-two scapulae underwent arthroscopic treatment for SSS. There were 74 scapulae that met the inclusion criteria, including having undergone surgery a minimum of 2 years earlier. An outcome questionnaire was completed for 60 of 74 (81%). The mean age was 33 years (range, 12-65 years), and the mean duration of symptoms before surgery was 4 years (range, 90 days to 20.4 years). The mean follow-up period was 3.4 years (range, 2-7 years). Eight scapulae failed initial surgical management (10.9%) because of recurrent pain and underwent revision surgery at a mean of 309 days (range, 120-917 days). After surgery, there was a significant improvement in all outcome scores, including SF-12 physical component summary score, from 39.2 to 45.4 (P = .002); SF-12 mental component summary score, from 45.0 to 49.6 (P = .023); American Shoulder and Elbow Surgeons score, from 52.6 to 75.8 (P < .001); and score on the short version of the Disabilities of the Arm, Shoulder and Hand questionnaire, from 40.2 to 24.2 (P = .001). The median patient satisfaction rating was 7 of 10. Greater age, lower preoperative psychological score, and longer duration of symptoms before surgery correlated with lower postoperative outcome scores., Conclusions: Arthroscopic surgery is an effective treatment for SSS in both primary and revision cases, showing significant improvements in all postoperative outcome scores at a mean of 3.4 years. Lower preoperative mental status score, longer duration of symptoms, and greater age were associated with poorer outcomes., Level of Evidence: Level IV, therapeutic case series., (Copyright © 2016 Arthroscopy Association of North America.

Background: Patient selection is critical when choosing between arthroscopic joint preservation and total shoulder arthroplasty in young patients with glenohumeral osteoarthritis (GHOA)., Purpose: To identify prognostic factors predictive of early failure in patients undergoing comprehensive arthroscopic management (CAM) for GHOA., Study Design: Case-control study; Level of evidence, 3., Methods: A total of 107 shoulders in 98 patients with minimum 2-year follow-up who underwent CAM were identified and evaluated. All shoulders met clinical and radiographic criteria for total shoulder arthroplasty (TSA), but the patients opted for joint preservation with arthroscopic management. Radiographic and preoperative factors were analyzed to determine predictors of early failure, defined as progression to TSA within the study period., Results: There were 72 men and 26 women with a mean age of 52 years (range, 29-77 years). Seventeen (15.8%) of 107 shoulders progressed to TSA at a mean of 2 years (range, 0.46-8.2 years). Shoulder status for the rest had a mean follow-up of 3.9 years (range, 2-9.4 years). There were a number of radiographic features that were correlated with early failure. Patients who failed had significantly less preoperative joint space than did those who succeeded (1.3 vs 2.6 mm; P = .004). Higher Kellgren-Lawrence grades for osteoarthritis and age older than 50 were also associated with failure. Shoulders with Walch type B2 and C glenoid were significantly more likely to fail than were Walch types A1, A2, and B1 ( P < .05)., Conclusion: The CAM procedure has been shown to reliably improve pain and function in active patients with advanced GHOA; however, it is important to inform patients about the limitations of the procedure. Patients with less joint space and abnormal posterior glenoid shape were significantly more likely to progress to early failure.

Background: There are little data on midterm outcomes after the arthroscopic management of glenohumeral osteoarthritis (GHOA) in young active patients., Purpose: To report outcomes and survivorship for the comprehensive arthroscopic management (CAM) procedure for the treatment of GHOA at a minimum of 5 years postoperatively., Study Design: Case series; Level of evidence, 4., Methods: The CAM procedure was performed on a consecutive series of 46 patients (49 shoulders) with advanced GHOA who met criteria for shoulder arthroplasty but instead opted for a joint-preserving, arthroscopic surgical option. The procedure included glenohumeral chondroplasty, capsular release, synovectomy, humeral osteoplasty, axillary nerve neurolysis, subacromial decompression, loose body removal, microfracture, and biceps tenodesis. Outcome measures included the American Shoulder and Elbow Surgeons (ASES), Single Assessment Numeric Evaluation (SANE), Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH), Short Form-12 (SF-12) Physical Component Summary (PCS), visual analog scale for pain, and satisfaction scores. Kaplan-Meier survivorship analysis was performed with failure defined as progression to total shoulder arthroplasty (TSA)., Results: Forty-six consecutive patients (49 shoulders) who underwent a CAM procedure at a minimum of 5 years from surgery were included. Two patients were excluded for refusing to participate before study initiation. The mean age at surgery was 52 years (range, 27-68 years) in 15 women and 29 men. All patients were recreational athletes with 7 former collegiate or professional athletes. Twelve shoulders (26%) progressed to TSA at a mean of 2.6 years (range, 0.5-8.2 years). For survivorship analysis, the status of the shoulder (preservation of the native joint or progression to TSA) at a minimum of 5 years was known for 45 of 47 (96%) shoulders. Survivorship was 95.6% at 1 year, 86.7% at 3 years, and 76.9% at 5 years. For surviving shoulders, minimum 5-year subjective outcome data were available for 28 of 32 (87.5%) shoulders at a mean of 5.7 years (range, 5-8 years). The mean (±SD) ASES score was 84.5 ± 17, the mean SANE score was 82 ± 18, the mean QuickDASH score was 15 ± 13, the mean SF-12 PCS score was 51.0 ± 9.1, and median patient satisfaction was 9 of a possible 10 points., Conclusion: This study demonstrates significant improvements in midterm clinical outcomes and high patient satisfaction after the arthroscopic CAM procedure for GHOA, with a 76.9% survivorship rate at a minimum of 5 years postoperatively. For patients looking for an alternative to TSA, the CAM procedure can provide reasonable outcomes and should be considered an effective procedure in appropriately selected, young active patients. Further studies are warranted to evaluate long-term outcomes and durability after this procedure., (© 2016 The Author(s).)

Background: Pediatric avulsion fractures of the anterior tibial spine are injuries similar to anterior cruciate ligament injuries in adults. Sparse data exists on the association between anterior tibial spine fractures (ATSFs) and injury to the meniscus or cartilage of the knee joint in children. This research presents a retrospective review of clinical records, imaging, and operative reports to characterize the incidence of concomitant injury in cases of ATSFs in children. The purpose of this study was to better delineate the incidence of associated injuries in fractures of the anterior tibial spine in the pediatric population., Methods: We identified 58 patients who sustained an ATSF and met inclusion criteria for this study between 1996 and 2011. The subjects were separated by the Myers and McKeever classification into type I, II, and III fractures, and each of these were subclassified by associated injury pattern., Results: 59% of children with an ATSF had an associated soft tissue or other bony injury diagnosed by magnetic resonance imaging or arthroscopy. The most prevalent associated injuries were meniscal entrapment, meniscal tears, and chondral injury. We found no meniscal or chondral injury associated with type I fractures. Twenty-nine percent of type II injuries demonstrated meniscal entrapment, 33% showing meniscal tears. Seven percent demonstrated chondral injury. Forty-eight percent of type III fractures had entrapment, whereas 12% showed meniscal tears. Eight percent had a chondral injury., Conclusions: A majority (59%) of displaced ATSF had either concomitant meniscal, ligamentous, or chondral injury. This finding suggests that magnetic resonance imaging evaluation is an important aspect of the evaluation of these injuries, particularly in type II and type III patterns. To date, this study reports the largest number of patients to evaluate the specific question of concomitant injuries in ATSFs in the pediatric population., Level of Evidence: Level IV.
