Clinical observation of patellar anaplasty and traditional knee arthroplasty in treatment of osteoarthritis / 局解手术学杂志

ABSTRACT

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 osteoarthritis 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.
