Comparison of the Efficacy of Unicondylar Replacement and Total Knee Arthroplasty in Patients with Medial Ventricular Osteoarthritis of Knee Joint
Objective To investigate the efficacy of single condyle replacement and total knee arthroplasty in the treatment of medial compartment osteoarthritis of the knee.Methods 80 patients with medial ventricular osteoarthritis of knee joint admitted to our hospital from January 2021 to May 2023 were selected as the study objects,and were divided into an observation group and a control group according to random number table method,with 40 cases in each group.The control group was treated with total knee replacement,and the observation group was treated with monocondylar replacement.The length of hospital stay,operation time,intraoperative blood loss,pain before and after operation,knee function level and postoperative complication rate were compared between the two groups.Results The hospital stay and operation time of observation group were shorter than that of control group,and the amount of intraoperative blood loss was less than that of control group,the difference was statistically significant(P＜0.05).The Visual Analogue Scale of pain score of observation group was lower than that of control group at 1,3 and 6 months after operation,and the difference was statistically significant(P＜0.05).At 1,3 and 6 months after operation,the Hospital form Special Surgery knee score of the observation group was higher than that of the control group,and the difference was statistically significant(P＜0.05).The incidence of postoperative complications in the observation group was lower than that in the control group,the difference was statistically significant(P＜0.05).Conclusion Compared with total knee arthroplasty,unicondylar knee arthroplasty for medial ventricular osteoarthritis of the knee has less intraoperative blood loss and shorter operative time,which can promote early postoperative recovery of patients,reduce postoperative pain,improve knee joint function,and lower the incidence of postoperative complications.
