关节内滑膜软骨瘤并不少见,约占全身关节游离体病的2％,双膝关节内巨大滑膜软骨瘤罕见。我们收治2例,现报告如下:例1:男性,40岁,哈族,牧民。双膝肿痛10年,加重2年.左膝髌上一骨性包块8年,右膝髌上骨性包块7年,初为红枣大小,疼痛轻微,包块逐渐增大,双膝关节肿胀、疼痛加重,活动受限,1993年11月26日入院.查体:双膝肿胀,左、右膝关节髌上分别可及6×7cm~2、5×8cm~2骨性包块,表面粗糙,活动度可,可及骨磨擦感。触痛(+)。左膝关节15°(伸)(?)90°(屈),右膝关节10°(伸)(?)90°(屈)。X光表现:双股骨髁上见大片状骨性致密影,边缘不规则,密度不均,有散在小低密度影。诊断:双膝关节滑膜软骨瘤病。于1993年12月9日分别由双膝前内侧切口手
Intra-articular synovial cartilage tumors are not uncommon, accounting for about 2% of total free body arthrosis, and rare synovial cartilage tumors in the joints of both knees. We treated 2 cases and the report is as follows: Example 1: Male, 40 years old, Kazakh, herdsmen. The knees are swollen for 10 years and aggravated for 2 years. The left knee has an upper bone mass for 8 years. The right knee has a bony mass for 7 years. The initial size of the jujube is slight pain and the mass increases gradually. Joint swelling, increased pain, limited mobility, admitted to hospital on November 26, 1993. Examination: swelling of both knees, left and right knee joints can reach 6 × 7cm ~ 2, 5 × 8cm ~ 2 bone mass respectively , The surface is rough, the degree of activity is available, and the sense of bone friction is available. Tenderness (+). Left knee joint 15° (extend) (?) 90° (flexion), right knee joint 10° (extend) (?) 90° (flexion). X-ray findings: Large bone-like dense shadows are seen on the double femoral condyle, with irregular edges, uneven density, and scattered low-density shadows. Diagnosis: Synovial chondromatosis in both knee joints. On December 9, 1993, the medial incision was made from both knees.
