膝关节单髁置换术中不同止血带使用策略的临床疗效研究
A clinical study on the therapeutic effects of different tourniquet utilization strategies in unicompartmental knee arthroplasty
摘要
Abstract
Objective To compare the effects of different methods of tourniquet on the early and mid-term effectiveness of unicompartmental knee arthroplasty(UKA).Methods A retrospective study was conducted on 80 patients who underwent UKA at the department of joint surgery,the First Affiliated Hospital of USTC from August 2023 to September 2023.Patients were divided into two groups according to tourniquet use:The whole process group(40 cases)and the optimised group(40 cases).In the whole process group,the tourniquet was used throughout the procedure,while in the optimised group,it was only used during prosthesis installation.Intraoperative blood loss,operation time,hospital stay,haemoglobin(Hb)levels,knee circumference 10 cm above the patella,visual analogue scale(VAS)knee pain scores,Hospital for Special Surgery(HSS)knee scores,Oxford knee score(OKS)and range of motion(ROM)were compared between the two groups.Results All patients were followed up for 12-15 months,with an average of(13.6±1.3)months.The operations in both groups were successfully completed and there were no serious intraoperative complications.The hospital stay for the whole process group was higher than for the optimised group,but the intraoperative blood loss and operation time for the whole process group were both lower than for the optimised group,with a statistically significant difference(P<0.05).Thigh circumference increased in both groups 24 h after surgery compared with pre-operative measurements,with a statistically significant difference in favour of the whole process group(P<0.05).During the follow-up period,no cases of contralateral knee compartment degeneration,surgical site infection,periprosthetic fracture,prosthesis wear or loosening occurred in either group.At the one-month postoperative follow-up,the optimised group showed better knee joint range of motion(ROM),visual analogue scale(VAS),Hospital for Special Surgery(HSS)and Oxford Knee Score(OKS)scores compared to the whole process group(P<0.05).However,at the 12-month follow-up,there were no significant differences in knee joint ROM,VAS,HSS,and OKS scores between the two groups(P>0.05).There were 4 cases of deep vein thrombosis in the whole process group and 0 case in the optimized group,and the two groups showed no statistically significant difference(P>0.05).Conclusion For patients undergoing unicompartmental knee arthroplasty,using a tourniquet only during prosthesis installation during surgery can effectively reduce postoperative limb swelling,although it increases intraoperative blood loss and operating time.Optimised tourniquet use is beneficial for the early curative effect and recovery of knee joint function,but has no significant effect on the mid-term curative effect in patients.关键词
