Background: Shoulder resurfacings represent approximately one-third of shoulder arthroplasties and have the highest revision rates of any shoulder arthroplasty. We present a survival analysis of the Global CAP hemi-resurfacing implanted by multiple surgeons with up to 10 years of follow-up. Methods: A life-table survival analysis of the Global CAP hemi-resurfacing was undertaken in a single site with multiple surgeons. Two survival analyses were performed; first, where failure was defined as component exchange and, second, where failure was defined as re-operation for any reason. Postoperative functional outcome was quantified using the Quick Disability Arm Hand and Shoulder Score (Quick DASH) and Oxford Shoulder Score (OSS). Results: Eighty-seven Global CAPs were implanted in 75 patients. At a mean (SD) follow-up of 5.4 years (2.5 years) (range 0.9 years to 10 years), five patients had revision surgery and three patients underwent a reoperation for any reason. Survival at year 7 with component exchange as the endpoint was 80% (95% confidence interval = 93 to 65) and survival with re-operation for any reason as the end point was 62% (95% confidence interval = 82 to 50). The mean OSS and Quick DASH were 35 and 27.6, respectively. Conclusions: The Global CAP has similar survivorship in the short to medium term and produces similar clinical outcomes compared to other shoulder resurfacings.
