Abstract：Objective To compare of ation effects of space balance technique and measurement osteotomy technique in total knee arthroplasty for severe knee osteoarthritis(KOA)patients.Methods A total of 102 patients with severe KOA admitted to Zhengzhou Yihe Hospital Affiliated to Henan University were enrolled as the research objects from January 2021 to March 2023.According to random number table method,they were divided into group A(51 cases)and group B(51 cases).Group A was treated with space balance technique,while group B was treated with measurement osteotomy technique.The perioperative indexes,osteotomy volume,angles of medial and lateral tibial joints and incidence of complications were compared between the two groups.Results The operation time of group A was shorter than that of group B,and the intraoperative blood loss was less than that of group B(P＜0.001).At 6 months after surgery,stress level of 90° medial and lateral knee bending in group A was lower than that in group B(P＜0.001).There was no difference in osteotomy volume of tibial plateau,medial femur and lateral hypocondyle,and incidence of complications within 6 months after surgery between the two groups(P＞0.05).Conclusion Space balance technique can shorten operation time,reduce intraoperative blood loss and relieve postoperative stress level of 90° medial and lateral knee bending in patients with severe KOA during total knee arthroplasty.
