    Abstract:
    OBJECTIVE: To investigate the prosthesis selection, precaution and curative effect of total knee replacement in severe gonarthrosis. METHODS: From January 1996 to July 2009, 50 patients (58 knees) with severe gonarthrosis underwent total knee replacement, included 12 males and 38 females, aged from 46 to 80 years with an average age of 66.5 years old. Six artificial hinged knee joints, 37 general knee joints and 15 ScorpioNRG knee joints were used according to the deformity of the knees. Fifty patients (58 knees) were followed up and evaluated with the HSS (the Hospital for Special Surgery Knee Score) scoring system. RESULTS: The duration of follow-up ranged from 6 months to 8 years (means 62 months). According to the HSS scoring system, the mean preoperative score was (38.6 +/- 8.76) points, and the postoperative score was (86.50 +/- 9.45) points. The clinical effect was excellent in 20 cases (23 knees), good in 28 cases (32 knees),and acceptable in 2 cases (3 knees). CONCLUSION: Stable and functional recovery knee joint without deformities and pains could be obtained after total knee replacement by carefully chosing of prosthetic replacements according to the different degrees of joint deformity of severe gonarthrosis.
