Autologous Fat Injection versus Lundborg Resection Arthroplasty for the Treatment of Trapeziometacarpal Joint Osteoarthritis.

Background: Various operative approaches exist for treatment of trapeziometacarpal joint osteoarthritis. The aim of this study was to compare the results of Lundborg resection arthroplasty with solely autologous fat injection.

Methods: Twenty-one patients with symptomatic osteoarthritis of the trapeziometacarpal joint (Eaton-Littler classification stages III/IV) underwent either a Lundborg resection arthroplasty (n = 12) or autologous fat injection into the trapeziometacarpal joint (n = 9).
