高屈曲后稳定型假体在全膝关节置换术中的应用及疗效评估
Application and Efficacy Evaluation of High Flexion Knee Prosthesis System in Total Knee Replacement
摘要
Abstract
Objective To investigate the clinical effects of high-flexion prosthesis in total knee replacement.Methods Total 70 knees in 56 patients with knee joint injury were given total knee replacement.The high-flexion prosthesis was replacd through center incision and patellar medial approach.The fixed situation of prosthesis was observed with X-ray,and the scores of knee and knee function were evaluated with KSS scoring system.Results At final follow-up examination,the range of knee motion was improved from (64.71± 24.27) ° preoperatively to (126.79 ± 8.60)° postoperatively.The maximum flexion was (132.07 ± 9.03)°.The average Knee Society knee scores improved from (36.36 ± 10.36) preoperatively to (90.91 ± 4.46),and the average Knee Society function scores improved from (32.50 ± 10.14) scores preoperatively to (78.61 ± 11.61) scores.The X-ray examination of two of knees in patients with OA and three of knees in patients with RA showed lucencies around the tibial prosthesis,but the radiolucencies were lower than 2 mm and were nonprogressive.Conclusion Total knee replacement with high-flexion prosthesis can provide satisfactory improvement in knee function for patients with knee joint disease.The short-term effect is definite,but the long-term effect needs further studies.关键词
