Ten-year outcomes of the Arpe prosthesis for the treatment of osteoarthritis of the trapeziometacarpal joint.

Ten-year outcomes of the Arpe prosthesis for the treatment of osteoarthritis of the trapeziometacarpal joint. Acta Orthop Belg. 2020 Mar;86(1):131-136 Authors: De Smet A, Vanhove W, Benis S, Verstraete M, Hollevoet N Abstract Outcomes of 66 Arpe prostheses in 50 patients treated for osteoarthritis of the trapeziometacarpal joint were investigated with a mean follow-up of ten years. Ten-year survival was 87% when failure was defined as implant removal followed by trapeziectomy and tendon interposition. Ten-year survival was 82% when revision of the cup was also considered as failure and it was 80% when replacement of the neck alone was also chosen as an endpoint. Of the 52 prostheses that were not revised mean DASH score was 11, mean pain score 1.2 and mean score for satisfaction 9.5. It can be concluded that the majority of patients who did not underwent revision surgery were satisfied and had little or no pain. However, long-term survival of the Arpe prosthesis was moderate and patients should be warned that after ten years the risk for reoperation might be up to 20%. PMID: 32490784 [PubMed - in process]
