髌骨整形术与传统膝关节置换术治疗骨关节炎的临床观察

目的观察髌骨整形术与传统膝关节置换术治疗骨关节炎的临床疗效。方法将我院收治的50例骨关节炎患者根据手术方法不同分为髌骨整形组与膝关节置换组,每组25例,术后对患者进行随访,观察2组患者随访时间、手术时间、术中出血、手术并发症、手术前后HSS膝关节功能评分和WOMAC骨关节炎指数评分。结果 2组患者在手术时间、术中出血、手术前后HSS评分、WOMAC评分以及影像学评价等方面比较差异均不具有统计学意义(P0.05);髌骨整形组患者的并发症发生率显著低于膝关节置换组,差异具有统计学意义(P0.05)。结论采用髌骨整形术与传统膝关节置换术治疗骨关节炎疗效可靠,均能有效改善患者的膝关节功能,但髌骨整形术的并发症发生率更低,值得进一步推广与研究。

Clinical observation of patellar anaplasty and traditional knee arthroplasty in treatment of osteoarthritis

Objective To observe the clinical effect of patellar anaplasty and traditional knee arthroplasty in the treatment of osteoarthri- tis. Methods According to the operation method,50 patients with osteoanhritis were divided into patellar anaplasty group and knee arthro- plasty group ,25 cases each. After surgery, all patients were followed up. Results The differences of the operation time, intraoperative blood loss, HSS score before and after operation ,the WOMAC scores and radiographic evaluation between two groups were not statistically significant （ P 〉 0.05 ）. The complication rate of patellar anaplasty group was lower than those of knee arthroplasty group significantly, and the difference between two groups was statistically significant （ P 〈 0.05 ）. Conclusion Patellar anaplasty and traditional knee arthroplasty can improve the patient＇s knee function effectively, and all the curative effect are reliable, but the complication rate of patellar anaplasty is lower, which is worthy of further promotion and research.
