## Overview Osteoarthritis of the carpometacarpal joint is degenerative joint disease of the lower knee joint. It is less common than middle-carpal osteoarthritis but causes similar signs of knee swelling, reduced flexion, and lameness that worsens with work. Radiographs show joint-space narrowing and osteophytes. ## Causes Repetitive loading, previous injury, or conformational stress. ## Diagnosis Lameness examination, diagnostic analgesia, and radiographs. ## Treatment Intra-articular medication, systemic anti-inflammatories, and workload adjustment. ## Recovery and Prognosis Fair. Management is ongoing. ## Prevention Sensible training and early treatment of joint inflammation.
