Total Knee Arthroplasty for Treatment of Severe Knee Joint Diseases in 118 Cases
摘要
A total of 118 patients (138 knees) who received total knee arthroplasty at the Department of Orthopedics, Guizhou Province People's Hospital between June 2000 and January 2007 were included in this study. These patients comprised 45 males and 73 females and were averaged (61±8) years old (range, 52-81 years). Of them, 28 (34 knees) suffered from rheumatoid arthritis, 6 (6 knees) from traumatic arthritis, 84 (98 knees) from severe osteoarthritis, 14 (18 knees) complicated by extraversion, and 25 (28 knees) complicated by inversion. Link Gemini knee prosthesis was used in 38 knees, Zimmer Nexgen knee prosthesis in 68 knees, and Depuy pfc sigma rotation platform knee system in 32 knees. All patients were followed up for an average of 28 months (range, 10 months-6 years). Prior to replacement, the mean knee score, according to the Hospital for Special Surgery (HSS) rating scale, was (34.00±7.65) points, and at the latest follow-up examination, it was (81.00±6.89) points. HSS score was excellent in 87 knees (63%), good in 43 knees (31%), and fair in 8 knees (6%). The excellent and good rate was 94%. Of 118 patients, 4 presented with infection and 3 showed deep venous thrombosis in lower limb following unilateral total knee arthroplasty and healed after anticoagulation and symptomatic therapy. There were 3 patients presenting with knee joint pains 2 months following knee joint arthroplasty. No knee joint red swelling and tenderness were found. Range-of-motion was basically normal. X-ray photograph indicated good position of prosthesis. Pains were relieved after femoral nerve block. All these findings suggest that total knee replacement is an effective method of treating severe knee joint diseases.
