Severity of osteoarthritis determined by radiographically measured width of the femoral and tibial condyles of the knee.
With osteophytes excluded, the width of the femoral and tibial condyles of 46 osteoarthritic knees in 31 patients was measured with standing anteroposterior radiographs. The ratio of femoral over tibial condylar width was smaller in the medial compartments in the knees with advanced osteoarthritis. This finding was interpreted to indicate that the tibial side widened as osteoarthritis advanced, a factor considered to be due to stress microfracture.
