Arthroscopic Management of Thumb Carpometacarpal Joint Arthritis.

The thumb carpometacarpal joint (CMCJ1) is born to have good freedom of motion. However, the excellent mobility at this joint also predisposes attenuation of capsuloligamentous structures, joint incongruity, instability, and osteoarthritis. The prevalence of radiographic CMCJ1 arthritis is high. There is no single ideal surgery for all stages of CMCJ1 arthritis, and for all kinds of patients. The arthroscopic approach seems to provide a better alternative with rewarding preliminary results. It includes arthroscopic synovectomy/debridement/thermal shrinkage, arthroscopic partial trapeziectomy and suture button suspensionplasty, and arthroscopic CMCJ1 excision/suture button suspensionplasty/K-wire fixation.
