In light of these findings, the senior surgeon (P.J.M.) has developed a joint-preserving arthroscopic strategy termed comprehensive arthroscopic management (CAM) for the treatment of young, active patients with symptomatic GHOA. This procedure addresses many of the potential sources of pain and dysfunction in the osteoarthritic shoulder through a combination of glenohumeral chondroplasty; extensive capsular release; and, when indicated, humeral osteoplasty, osteophyte excision, axillary nerve neurolysis, subacromial decompression, loose body removal, microfracture, and biceps tenodesis. In a previously published article on the first 29 patients (30 shoulders) to receive the CAM procedure, patients were found to have a significant reduction in pain and improved range of motion with increased functional outcome scores. Furthermore, the procedure demonstrated 85% survivorship at 2 years. Glenohumeral joint space of less than 2 mm was found to be predictive of progression to TSA. Midterm results in a similar group of patients also demonstrated encouraging findings with 77% survivorship at a minimum 5-year follow-up, with successful patients noting significant improvements in pain, range of motion, and function.
The promising short- and midterm results suggest that the CAM procedure is effective in managing GHOA and delaying the need for TSA in young, active individuals who wish to extend the life span of their native shoulder joint. However, the data are limited by the small sample size and inability to provide surgeons with definitive preoperative patient selection criteria. Despite this, the data do imply that some patients may be more appropriate candidates for this procedure than others, and despite encouraging preliminary results, identifying the factors that are predictive of early failure is paramount for proper patient selection for those who will do well with joint preservation versus replacement. Differentiating those patients who are less ideal candidates for arthroscopic intervention may also lead to improved long-term results by avoiding multiple surgical interventions. Therefore, the purpose of this study is to examine prognostic factors predictive of early failure in patients undergoing the CAM procedure for GHOA. We hypothesized that radiographic joint space narrowing and lower preoperative patient-reported scores would be predictive of early failure of the CAM procedure. Results from this analysis will assist surgeons in selecting proper candidates for this joint-preserving intervention to optimize durability and long-term outcomes.
