Abstract
Treatment of glenohumeral arthritis in young patients after failure of nonoperative measures presents a unique clinical challenge. Concerns about wear and loosening of polyethylene glenoid prostheses have led many surgeons to consider hemiarthroplasty in this patient group. Both non-prosthetic glenoid arthroplasty (NPGA; “ream and run”) and meniscal allograft interposition (MAI) have shown promise for improving function and comfort in single-surgeon case series, but no comparative study has yet been performed to compare the relative efficacy of each method. The purpose of this work is to present interim results of a prospective, randomized clinical trial with minimum two-year follow-up of all reported patients.
