PURPOSE: To evaluate if @entity2530 diagnosed on MR images of the knee relates to reduced @entity79 ( @entity79 ) and may be caused by an insufficiency @entity174 . MATERIAL AND METHODS: Thirty-two consecutive @entity1 (8 @entity1 , 24 @entity1 ; age range 27-82 years, mean 62 years) with MR findings of @entity2530 of the femoral or tibial condyle were prospectively included. Trabecular and cortical @entity79 were measured with high resolution peripheral quantitative CT in the non-dominant distal radius and the tibia of the involved extremity. One tibia was not measured due to @entity85 . RESULTS: The mean trabecular @entity79 of the radius was 81% of the young-adult average peak @entity79 (range 19-160%). The mean cortical @entity79 in the radius was 86% (range 63-108%). The mean trabecular @entity79 in the tibia was 92% (range 28-160%). The mean cortical @entity79 in the tibia was 86% (range 49-132%). The values of the trabecular bone of the distal radius (tibia) were normal in 11 (15) @entity1 , @entity6092 in 12 (4), and osteoporotic in 9 (12), respectively. The cortical bone values of the distal radius (tibia) were normal in 12 (13) @entity1 , @entity6092 in 12 (12), and osteoporotic in 8 (6), respectively. CONCLUSION: @entity170 and @entity2331 are commonly found in @entity1 with @entity2530 of the knee as diagnosed on MR images. This indicates that for some @entity1 an insufficiency mechanism may be responsible for the MR findings. However, in the @entity1 with normal bone density other reasons for @entity2530 may be present.
