Abstract

BACKGROUND Published data on the outcome of Copeland shoulder resurfacing arthroplasty (CSRA) are limited. This observational case series study reports the functional and radiological outcome of CSRA during a mean follow-up of 4 years and highlights the correlation between key outcome measures. METHODS One-hundred two consecutive patients with osteoarthritis (OA-47.1%), rheumatoid arthritis (RA-40.2%), rotator cuff arthropathy (RCA-8.8%), and avascular necrosis (AVN-3.9%) underwent CSRA. The outcome assessment included pain and satisfaction, physical limitation, Oxford Shoulder score (OSS), Constant score (CS), and SF-12. Imaging was reviewed for glenoid morphology (Walch classification) and humeral head (HH) migration. RESULTS Highest patient satisfaction and lowest pain levels were related to the primary pathology with AVN best followed by OA, RA, and with RCA having the poorest outcome. Comparing the two largest groups the CS was significantly higher in OA (61 ± 21.3) than RA (44 ± 20.5). OSS showed a significant correlation with CS and physical subscale of SF-12. Walch type A (67.6%) and HH migration (47%) were the commonest radiographic observations. OSS, CS, pain, and satisfaction were significantly different between migration and nonmigration groups. CONCLUSION The CSRA resulted in satisfactory outcome in many patients. AVN and OA were associated with the best and RCA with the poorest results. The CSRA was associated with glenoid erosion and HH migration particularly in RCA. CSRA remains an option in the treatment of arthritic conditions of the shoulder but its future use may be limited to younger patients where implanting a glenoid may be regarded as problematic.
