全膝关节置换中采用测量截骨与间隙平衡技术的对比分析.

BACKGROUND: Total knee arthroplasty is often used to treat knee joint diseases. The intraoperative osteotomy mainly measures osteotomy and gap balance technology, which can ensure the stability of prosthesis implantation and improve the prognosis by reasonable osteotomy. OBJECTIVE: To statistically analyze the clinical efficacy of the osteotomy and gap balance technique in patients undergoing total knee arthroplasty. METHODS: Data of 76 cases of primary osteoarthritis from May 2015 to October 2016 were collected. The patients were divided into control and trial groups (n=38/group). The control group used the measurement osteotomy technique, and the trial group used the gap balance technique to compare the surgical indexes and prognostic effects at 1 year postoperatively. RESULTS AND CONCLUSION: The femoral distal osteotomy and thickness of polyethylene liner in the trial group were significantly higher than those in the control group at postoperative 3 days (P < 0.05). Compared with the control group, the knee joint stability and knee flexion 90° femoral angle were improved better in the trial group (P < 0.05). The excellent and good rate of the lower limb strength and the anatomical axis of the lower leg in the control and trial groups was 47% and 61%, respectively (P > 0.05). There was no case of loosening of the prosthesis in the two groups during the follow-up, and there were no significant differences in other complications (P > 0.05). After 1 year of follow-up, the Visual Analogue Scale and Western Ontario and McMaster Universities Osteoarthritis Index pain scores in the trial group were significantly decreased, and the Knee Society Score function was significantly improved (P < 0.05). These results imply that the gap balance technique used in total knee arthroplasty, can significantly improve the clinical symptoms and prognosis. [ABSTRACT FROM AUTHOR]
