We tested the accuracy of MRI for the precise quantification of the volume of osteonecrosis in 30 hips (stage III). The values were compared with direct anatomical measurements of the femoral heads obtained after total hip replacement. When the area of osteonecrosis was determined visually, and manually outlined on each slice, the accuracy of the(More)
Chondral lesions of the knee are frequent during arthros-copy (63% of cases), and the deep lesions are principally localized on the condylars. 1 These lesions are posttrau-matic, dystrophic (osteochondritis dissecans), or degenera-tive (osteoarthritis). The evaluation of depth and size of these chondral lesions is essential when making a therapeutic(More)
PURPOSE To present a new method of arthroscopic measurement of the surface and location of condylar lesions. METHODS We propose measuring the height of the condylar lesion by using the lesion's arc (Δ°) obtained from the difference between the angle of flexion at the beginning of the lesion and the angle of flexion at the end of the lesion. The first goal(More)
