Return to Sport Following Hemiarthroplasty With Concentric Reaming Versus Total Shoulder Arthroplasty: A Matched Pair Analysis

摘要

The purpose of this study was to establish functional outcomes regarding return to sport activity for patients receiving anatomical total shoulder arthroplasty (aTSA) vs the ream and run procedure (hemi RR). Patients who underwent hemi RR and who underwent a ISA with a polyethylene glenoid component for end-stage glenohumeral arthritis were retrospectively identified from 2000 to 2014. Patients were matched regarding age, body mass index, sex, and hand dominance. Patients were surveyed to determine their level of sport and satisfaction after surgery. At a mean follow-up of 69.1 +/- 24.8 months, a total of 26 hemi RR and 30 aTSA patients met inclusion/exclusion criteria. Mean +/- SD age at the time of surgery was 53.0 +/- 8.5 years. there was no statistical difference between the two cohorts regarding patients who reported no postoperative problems (69.2% vs 76.7%, P=.529), reoperation (11.5% vs 6.7%, P =. 322), return to overall sport (94.4% vs 86.4%, P=.395), return to high-demand upper-extremity sport (92.3% vs 81.3%, P=.390), and return to same or better level of intensity sport (83.3% vs 72.7%, P=.424). Patients returned to sport at a mean of 7.5 +/- 5.7 months and 6.2 +/- 3.6 months in the hemi RR and aTSA cohorts, respectively (P =.485). Radiographic measurements of medialization (mean, -2.4 +/- 5.0 vs -2.2 +/- 5.7; P=.913) and postoperative decentering (mean, 3.6%+/- 12.6% vs 4.3%+/- 13.3%; P=.795) were equivalent for the two cohorts. Hemi RR was found to have high and equivalent rates of sporting outcomes, clinical outcomes, and radiographic outcomes compared with aTSA. As appropriately indicated patients are counseled for surgery, realistic expectations regarding sports should be discussed.
