Published results showed high and equivalent rates of sporting, clinical and radiographic outcomes between patients who underwent hemiarthroplasty with concentric reaming and patients who underwent anatomical total shoulder arthroplasty.

Anirudh K. Gowd , MD, and colleagues surveyed 26 patients who underwent hemiarthroplasty with concentric reaming and 30 patients who underwent anatomic total shoulder arthroplasty (TSA) for end-stage glenohumeral arthritis to determine the level of sport and satisfaction after surgery. Researchers matched patients based on age, BMI, sex and hand dominance.

Results showed no statistical differences regarding patients who reported no postoperative problems, reoperation, return to overall sport, return to high-demand upper extremity sport and return to the same or better level of intensity sport between the two groups. Researchers found patients in the hemiarthroplasty group returned to sport at a mean of approximately 7.5 months vs. 6.2 months in the anatomic TSA group. The hemiarthroplasty group had radiographic measurements of medialization and postoperative decentering that were equivalent to the anatomic TSA group, according to results.

“Patients receiving hemiarthroplasty with concentric glenoid resurfacing achieved a high rate of return to low- and high-intensity sport with a mean follow-up of over 6 years. These outcomes were equivalent to that of a match-paired cohort of patients receiving total shoulder arthroplasty,” Gowd told “This study emphasizes the safety and efficacy of performing this operation for well-indicated and active patients.” – by Casey Tingle
