Abstract:
OBJECTIVE: To study the therapeutic effect of treating knee arthropathy with total knee arthroplasty using rotating-platform knee prosthesis. METHODS: A total of 62 patients (74 knees) in Provincial Hospital Affiliated To Shandong University from January 2005 to January 2009 were selected, including 36 males (41 knees) and 26 females (33 knees), aged 52-79 years, mean aged 61.5 years; 28 cases with left knee, 22 cases with right knee and 12 cases of both knees. The cases were composed of 34 cases with osteoarthritis, 21 cases with rheumatoid arthritis and 7 cases with traumatic arthritis. All the patients received the total knee arthroplasty for the first time using rotating-platform knee prosthesis, no replacement of the patella. The clinical results of pre-operetion and after-operation were evaluated by the HSS knee rating score system. RESULTS: All the patients were followed-up for averaged 22 months (3-48 months) after operation. Incisions of all the cases were healed, and there was no infection and hematoma. Lower extremity deep venous thrombosis occurred in 2 cases at 3 days after operation. Swelling disappeared through drug treatment 10 days later. Pain and function of all the patients were obviously ameliorated after operation. The average HSS knee rating score was 44.99 (from 34 to 58) before total knee arthroplasty, which was improved to 88.78 (from 69 to 98), and the good-to-excellent rate was 98% (excellent 45 cases, good 16 cases, average 1 case). There were no signs of prosthetic dislocation or loosening in the X-ray films. CONCLUSION: Total knee arthroplasty using rotating-platform knee prosthesis owns advantages of easy surgical operation, tess complications, good recovery and satisfactory results in a short-term.
