Trapeziometacarpal Joint Arthroplasty: Medium-Term Clinical Outcomes and Survival.

Trapeziometacarpal joint (TMC) arthroplasty (TMA) is a treatment option for failed symptomatic treatment of basal thumb arthritis. This study aimed to evaluate clinical and radiological outcomes and complications of Maïa™ prosthesis (Groupe Lépine, Genay, France) since its introduction in our institution with a minimum of three years follow-up. We performed a retrospective study of patients with TMA treated with Maïa prosthesis.
