Spontaneous rupture of the quadriceps tendon has heen rarely reported. We experienced four knees of 3 patients. Two patients with chronic renal failure(CRF) had been treated with peritoneal dialysis and the other patient was healthy without significant medical problem. In the CRF patients, laboratory studies were coincided with secondary hyperparathyoidism. Radiologic and operative findings suggested that the repeated minor trauma caused avulsion fracture of the bone near the insertion site of the tendon. Histologic findings revealed no elastosis of the tendon and no deposit of amyloid in the quadriceps tendon. In the non-CRF case, there was normal lahoratory data, and the rupture occurred at the musculotendinous junction, suggesting sudden contracture of the muscle causing failure without trauma history. All cases were treated successfully with open repair of the quadriceps tendon. It could be summarized that the site of spontaneous rupture in the CRF and normal patient were different.

The purpose of this study was to evaluate the effect of estrogen receptor on the degenerative change of articular cartilage by observation of different changes of histology, matrix glycosaminoglycan and chondrocyte proliferation. In sixty-four Newzealand rabbits, experimental instability was made to induce degenerative changes by sectioning the anterior cruciate ligament, medial collateral ligament and medial meniscus of the left knees. In the oophorectomy group (32 rabbits), knee surgery was performed at 6 weeks following bilateral oophorectomy. In the non-oophorectomy group (32 rabbits), knee surgery was performed without oophorectomy. Four rabbits were killed at 0, 1, 2, 4, 8, 12, 16, 20 weeks, respectively, after the knee operation. Total immunohistochemical scores of estrogen receptor were evaluated between the two groups. Histologic evaluation of H-E staining was conducted by alcian blue staining. Evaluation of chondrocyte proliferation was carried out by immunohistochemistry using monoclonal antibody to 5-bromo-2 -deoxyuridine. The stainability of each staining was calculated using semi-quantitative analysis and statistical differences were evaluat- ed by ANOVA test and LSD multiple comparison test. Total immunohistochemical scores of estrogen receptor in the non-oophorectomy group were higher than the oophorectomy group (P<0.05). In the non-oophorectomy group, the histologic scores and the histochemical scores of glycosaminoglycan were lower than the oophorectomy group after 4 weeks and 8 weeks respectively (P<0.05). The immunohistochemical score of BrdU was the highest at 2 week and then decreased after 4weeks in both groups. The immunohistologic scores of non-oophorectomy group was significant higher than oophorectomy group between 1 and 4 weeks (P<0.05). Our results suggested that the estrogen might aggravate the degenerative change of the knee joint in rabbits by decreasing matrix glycosaminoglycan and increasing chondrocyte proliferation.
