Arthritis Shoulder

This is a multicenter, prospective, non-controlled post market surveillance study. The objectives of this study are to confirm the safety, performance, and clinical benefits of the Zimmer Biomet Shoulder Arthroplasty systems in primary anatomic shoulder arthroplasty and its instrumentation. Safety of the systems will be assessed by monitoring the frequency and incidence of adverse events. The performance and clinical benefits will be evaluated by assessment of the overall pain and functional performance, qualify of life, and radiographic parameters of all enrolled study subjects.

There are no published prospective studies that compared 2-year functional outcomes of RTSA and anatomic TSA for the treatment of primary glenohumeral osteoarthritis with intact rotator cuffs and no excessive glenoid retroversion. The primary goal of our prospective randomized study is to determine whether RTSA have at least as good results as anatomic TSA (non-inferiority), in patients with glenohumeral osteoarthritis, without rotator cuff tears nor significant glenoid retroversion.

The purpose of this double-blind randomized controlled trial is to compare patient-reported, clinical, and functional outcomes in patients undergoing RTSA with and without subscapularis repair after placement of a modern "lateralized" implant over the course of 24-months postoperative.

The purpose of this study is to compare the efficacy of intra-articular corticosteroid injections versus platelet-rich plasma injections for non-operative treatment of primary glenohumeral osteoarthritis. The efficacy of intra-articular injections, outside of hyaluronic acid, for the treatment of glenohumeral OA is not known, yet these treatments are commonly used with hopes of providing patients with symptomatic relief that can hopefully delay or prevent the need for shoulder arthroplasty. This study will help elucidate the therapeutic benefit of corticosteroid and Platelet Rich Plasma (PRP) injections in this patient population.

The purpose of this study is to demonstrate safety and efficacy of the Mirror Medacta Shoulder System in total shoulder arthroplasty.
