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, wit
