Frequency of XXXX of the knees and avascular necrosis of the femoral heads in @entity210 : a controlled study.

@entity1 @entity8 @entity571 @entity4850 @entity603 @entity209 @entity210 @entity2738
An association between urate @entity210 and @entity4850 has been suggested in several studies, but the situation remains ill-defined because of lack of appropriate controls, small numbers of @entity1 studied, or retrospective investigation. An association has also been claimed between @entity210 and @entity2738 . 138 @entity1 with @entity210 and 142 non-gouty control subjects were carefully matched for age and x-rays were taken of the knees and pelvis. Chondrocalcinosis of the knees was detected in 8 @entity1 with @entity210 (5.8%), no cases being found in the control group. The difference is significant (P less than 0.025). Deposits were linear or irregular. Six of the 8 @entity1 gave a history of acute @entity603 of the knees; fluid had been aspirated in 2 of them, urate crystals being found in one and no crystals in the other. Six of 8 @entity1 showed evidence of @entity4850 elsewhere. No association was apparent between @entity4850 and the presence of tophaceous deposits or @entity8 , though the duration of @entity210 appeared to be longer in the @entity1 with @entity4850 than in the other @entity210 @entity1 and @entity571 of the knees commoner. There was no evidence of other @entity209 commonly associated with @entity4850 . No cases of @entity2738 were found.
