title: Ten-year long-term results of total joint arthroplasties with ARPE® implant in the treatment of trapeziometacarpal osteoarthritis.
abstract: Between May 1999 and April 2002 a total of 69 consecutive thumb carpometacarpal joint arthoplasties were performed in a total of 64 patients for carpometacarpal joint osteoarthritis using the cementless hydroxyapatite (HA)-coated unconstrained ARPE implant. Clinical, functional and radiological results at 10-year follow-up are presented. Survival analysis was performed using the Kaplan-Meier method. Of the 64 patients, four were lost to follow-up, 60 implants (92.3%) were functional and five (7.7%) were not (two dislocated, two were removed and one with aseptic loosening). Survival estimate for functional implants over 10 years was 93.9% (95% confidence interval 82.3-97.9). The radiographs were satisfactory in 82.4%. There was subsidence of the cup in 15.8%. Thumb carpometacarpal joint arthroplasty with the ARPE implant offers a reliable treatment alternative in patients with Eaton grade III or IV thumb carpometacarpal joint arthritis in the presence of good bone stock.
