## Overview Osteochondrosis of the trochlear ridges is a developmental lesion of the femoral trochlea in the stifle, overlapping with OCD. Defective cartilage ossification creates flaps or fragments. Young horses show stifle effusion and lameness. Arthroscopic treatment is standard. ## Causes Failure of normal endochondral ossification. ## Diagnosis Radiographs and arthroscopy. ## Treatment Arthroscopic debridement. ## Recovery and Prognosis Good for most lesions. ## Prevention Controlled growth and nutrition.
