Fig. 2From: Associations between the morphological parameters of proximal tibiofibular joint (PTFJ) and changes in tibiofemoral joint structures in patients with knee osteoarthritisAssociations between the areas of PTFJ and change in tibial cartilage volume per annum. The contacting area and load-bearing area of PTFJ were significantly associated with increased loss of cartilage volume at the medial (A, B) but not the lateral (C, D) tibial site. Partial r and p values were obtained after adjustment for age, sex, height, weight, and total tibial bone sizeBack to article page
