The prevalence of chondrocalcinosis in the human knee joint. An autopsy survey


, : The prevalence of chondrocalcinosis in the human knee joint. An autopsy survey. Journal of Rheumatology 15(4): 633-641

The prevalence of pathological calcifications in the menisci and articular cartilage of both knees was investigated macroscopically and radiologically in 130 consecutive autopsies. The mean age of the subjects was 72 .+-. 13 years. Only 8 subjects were less than 50 years old. All had been admitted to hospital and no patient had a history of joint disorders. Half of the patients were male. Calcifications were found in 27 (20.7%) cases, all over 60 years of age. There were 15.4% males and 26.1% females affected. The incidence of intraarticular calcifications in females increased from 11.1-37.5% and in males from 20-29.4% for the 60-69 year age group and the over 80-year age group, respectively. One third of affected cases had only meniscal and 2/3 had both meniscal and chondral calcifications. Isolated meniscal calcifications were found more often in 1 and mixed meniscal and chondral calcifications were found in both knees. Severe destructive articular cartilage lesions were observed significantly more often in joints with intraarticular calcifications than in joints of age matched subjects without calcifications. Joints with calcifications showed little evidence of synovial inflammation. Similarly, no specific relationship was found between the presence of crystal and amyloid deposits in the knees examined.
