Clinical Study Of Preoperative Pre-Rehabilitation In Improving Balance And Walking Function Of Patients After Unilateral Total Knee Arthroplasty

BackgroundAt present,the most effective treatment to improve the function of severe knee osteoarthritis is total knee arthroplasty(TKA),which has been perfected and the clinical effect has been affirmed by a large number of medical workers and patients.However,there is a risk of decreased proprioceptive control,limited joint movement or venous thrombosis of lower extremities after operation,which will affect the recovery of balance and walking function.Early rehabilitation training after operation has been proved to be beneficial to the recovery of knee joint function,balance and walking function,shorten the time of bed rest,and promote patients to return to daily life faster and better.In recent years,preoperative pre-rehabilitation improves the functional reserve of patients,which provides a new intervention idea for improving the prognosis of operation.There is still some controversy about whether pre-rehabilitation intervention is carried out before TKA.In this study,pre-rehabilitation training was conducted to explore whether it affects the balance of patients and the clinical effect of walking function after operation.ObjectiveTo observe the clinical effect of preoperative pre-rehabilitation on improving the balance and walking function of patients after unilateral total knee arthroplasty,so as to provide clinical basis for improving the rehabilitation treatment of TKA.MethodsAll TKA patients who met the inclusion criteria in the Department of Orthopaedics of Henan University people's Hospital(Henan people's Hospital)from March 2019 to December 2019 were selected as subjects.A total of 53 patients who met the inclusion criteria were randomly divided into control group(n = 27)and experimental group(n = 26).Both groups were given routine postoperative rehabilitation treatment,and the experimental group was given pre-rehabilitation intervention before operation.Pain score(VAS),rangeof motion(ROM),(HSS)knee score,Berg balance scale score(BBS)and 10-meter walking test(10MWT)were performed in both groups at 1 day before operation,1 week and 1 month after operation.ResultsOne week after operation,the VAS pain score,the range of motion of knee joint,the score of American Special surgery Hospital,the score of Berg balance scale and the results of 10-meter walking test in the two groups were significantly improved as compared with those before operation(P<0.05).One week after operation,there was no significant difference in VAS and ROM between the two groups,but the HSS,BBS and 10 MWT in the pre-rehabilitation group were better than those in the control group,and there was significant difference between the two groups(P<0.05).There was no significant difference in the results of VAS,ROM,HSS,BBS and 10 MWT between the two groups one month after operation.ConclusionPreoperative pre-rehabilitation can significantly improve the knee joint function,balance function and walking function of patients undergoing total knee arthroplasty.
