Outcomes of primary arthroscopic shoulder stabilization in active patients over 40—results at a mean follow-up of 7 years

The purpose of this study is to report clinical outcomes, return to activity, redislocation rate, and rate of conversion to arthroplasty for active patients over age 40 undergoing primary arthroscopic shoulder stabilization. Patients over 40 years of age who underwent arthroscopic capsulolabral repair for shoulder instability between December 2005 and January 2018 with a minimum of 2-year postoperative follow-up were enrolled in this retrospective, monocentric study. Clinical outcome scores including the 12-Item Short-Form Survey, American Shoulder and Elbow Surgeons (ASES), Quick Disabilities of the Arm, Shoulder, and Hand, Single-Assessment Numeric Evaluation, and visual analog scale pain were collected. Additionally, it was determined which patients reached the minimal clinically important difference and the patient-acceptable symptom state for the ASES score. Bivariate analysis was utilized to determine if there was any association between baseline demographic and clinical factors with the outcome scores. Of a total of 814 patients assessed for eligibility, an aggregate of 40 patients were included and 33 patients (8 females) were available for follow-up. The average age was 49.4 ± 7.6 years. At an average follow-up of 7.0 ± 3.6 years, all the outcome scores significantly improved compared to baseline. These included ASES (69.9 ± 19 to 95.8 ± 7.6, P
