Mirror Medacta Shoulder System Pivotal Trial

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

Three Year Outcomes After Shoulder Arthroplasty

The purpose of this multicenter observational cohort study is to evaluate three-year outcomes in adults who underwent anatomic or reverse total shoulder arthroplasty using a contemporary shoulder implant system. The main questions it aims to answer are: Are three-year patient-reported outcomes after anatomic total shoulder arthroplasty comparable to those after reverse total shoulder arthroplasty? How often do the implants used during surgery differ from the preoperative three-dimensional (3D) surgical plan, and are these differences associated with patient outcomes, complications, or revision surgery? Researchers will compare patient-reported outcomes, function, complications, and revision rates between patients who underwent anatomic and reverse total shoulder arthroplasty. Researchers will review participant existing medical records and surgical information. Participants whose two- or three-year outcome measures are not available may be asked to complete a one-time questionnaire by telephone or secure electronic survey. No treatments or additional clinical procedures will be performed as part of this study.

Zimmer Biomet Shoulder Arthroplasty PMCF Study

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.

Anatomic TSA vs RTSA for Glenohumeral Arthritis

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.

Efficacy of Intra-articular Injections for the Treatment of Primary Glenohumeral Osteoarthritis(GHOA)

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.
