Trapeziometacarpal total joint arthroplasty for osteoarthritis: 199 patients with a minimum of 10 years follow-up

Abstract

We report outcomes of 228 consecutive patients with total joint arthroplasty using the Arpe® prosthesis, among which 216 trapeziometacarpal joints in 199 patients had a minimum of 10 years follow-up. The cumulative survival rate of the 216 implants at 10 years using the Kaplan-Meyer method was 93%. Two hundred joints were functional and painless. We found good integration and positioning of the components in 184 (93%) of the joints. Sixteen prostheses failed. We conclude that this implant has acceptable long-term survival rate and restores good hand function. We also report our methods to improve implant survival and to decrease the risk of component malpositioning, and failure rate. <b>Level of evidence:</b> II.
