The radiographs and medical records were reviewed of 76 @entity1 who presented with @entity4850 over a period of two years. Two groups of @entity1 could be distinguished. The first group consisted of 58 mostly elderly @entity1 (age 53-89 years [mean 71.8]). In these, @entity4850 was most likely to be caused by an underlying disease such as @entity460 crystal deposition disease or it was present in association with @entity571 . In most cases of this group the findings were bilateral. The second group consisted of 18 @entity1 who were significantly younger (age 15-69 years [mean 43.1]). In these @entity1 there was no evidence of an underlying disease. @entity4850 was seen in only one joint, which had sustained damage by surgery or @entity130 . The knees were affected in the majority of cases and meniscectomy was believed to be the previous @entity130 in most of these cases. The hands were involved in two @entity1 , the wrist, shoulder, or elbow were involved in other @entity1 . In two cases with @entity4850 in the hand and knee, the findings disappeared several weeks to months after the injury. The findings in the group of @entity1 with a history of @entity130 or surgery and no other disease, support the concept that @entity4850 may result from previous joint damage.
