Osteoarthritis (OA) of the thumb carpometacarpal (CMC) joint is a common disease in hand OA. Low joint congruity could increase articular stress in the CMC joint and is thus considered among the risk factors for CMC OA. However, this relationship has not been clarified. This study aimed to examine w...
