N2 - Background: The role of cementless surface replacement arthroplasty (CSRA) in young individuals is currently unclear. The aim of this study was to evaluate CSRA long-term results for glenohumeral arthritis in young patients. Methods: Between 1990 and 2003, 54 CSRAs were performed on 49 patients (25 men, 24 women) aged younger than 50years. Mean age was 38.9years (range, 22-50years). Three patients (4 shoulders) died over time and 8 were lost to follow-up, leaving 38 patients (42 shoulders) with a mean follow-up of 14.5years (range, 10-25years). There were 17 total shoulder replacements with metal back glenoid, and 37 underwent humeral head resurfacing with microfracture of the glenoid. Results: The indications were avascular necrosis, 16; rheumatoid arthritis, 20; instability arthropathy, 7; primary osteoarthritis, 5; fracture sequelae, 3; postinfection arthritis, 2; and psoriatic arthritis, 1. The mean relative Constant score increased from 11.5% to 71.8% (P<.0001), and the mean patient satisfaction at final follow-up was 8.7 of 10. The mean relative Constant score for the humeral head resurfacing with microfracture of the glenoid improved to 77.7% compared with 58.1% for total resurfacing arthroplasty. Two required early arthrodesis due to instability and deep infection. Seven were revised to stemmed prosthesis: 1 for traumatic fracture and 1 for glenoid erosion 16years after the index procedure. Five shoulders in 4 patients (4 rheumatoid arthritis, 1 avascular necrosis) were revised at 8 to 14years after surgery for cuff failure and loosening. Three were revised to stemless reverse total shoulder arthroplasty due to rotator cuff failure at 23, 16, and 13years after surgery. Conclusions: CSRA provides good long-term symptomatic and functional results in the treatment of glenohumeral arthropathy in patients aged younger than 50years in 81.6% of the patients. This improvement is maintained over more than 10years after surgery, with high patient satisfaction (8.7 of 10). However, 10 shoulders (of 54) (18.5%) underwent revision arthroplasty. Resurfacing offers a valuable tool in treating young patients with glenohumeral arthritis, providing reasonably good long-term results in 81.6% of the patients, while allowing preservation of bone stock if the need for revision arises. All the revision arthroplasty options are preserved, including less invasive procedures.
