Early Postoperative Measures Predict 1- and 2-Year Outcomes After Unilateral Total Knee Arthroplasty: Importance of Contralateral Limb Strength

Background Total knee arthroplasty (TKA) has been shown to be an effective surgical intervention for people with end-stage knee osteoarthritis. However, recovery of function is variable, and not all people have successful outcomes. Objective The aim of this study was to discern which early postoperative functional measures could predict functional ability at 1 year and 2 years after surgery. Design and Methods One hundred fifty-five people who underwent unilateral TKA participated in the prospective longitudinal study. Functional evaluations were performed at the initial outpatient physical therapy appointment and at 1 and 2 years after surgery. Evaluations consisted of measurements of height, weight, quadriceps muscle strength (force-generating capacity), and knee range of motion; the Timed “Up & Go” Test (TUG); the stair-climbing task (SCT); and the Knee Outcome Survey (KOS) questionnaire. The ability to predict 1- and 2-year outcomes on the basis of early postoperative measures was analyzed with a hierarchical regression. Differences in functional scores were evaluated with a repeated-measures analysis of variance. Results The TUG, SCT, and KOS scores at 1 and 2 years showed significant improvements over the scores at the initial evaluation (P<.001). A weaker quadriceps muscle in the limb that did not undergo surgery (“nonoperated limb”) was related to poorer 1- and 2-year outcomes even after the influence of the other early postoperative measures was accounted for in the regression. Older participants with higher body masses also had poorer outcomes at 1 and 2 years. Postoperative measures were better predictors of TUG and SCT times than of KOS scores. Conclusions Rehabilitation regimens after TKA should include exercises to improve the strength of the nonoperated limb as well as to treat the deficits imposed by the surgery. Emphasis on treating age-related impairments and reducing body mass also might improve long-term outcomes.

Background:Total Knee Arthroplasty (TKA)1is a common surgical treatment for severe knee Osteoarthritis (OA)2, which generally improves pain, physical function, quality of life and possibly fall risk. Fall risk increases for older adults with severe knee OA; however it has not been studied extensively whether this parameter is improved after TKA.Objective:To investigate: a) the history and frequency of falls, including mechanism or causes of falls, injuries sustained from falls reported, activity during falling and location of falls and, b) the factors affecting falls, a year after TKA in elderly patients with severe knee OA.Patients and Method:An observational prospective longitudinal study of 68 patients (11 males and 57 females) was conducted. The frequency of falls was recorded every month after knee replacement for a year period. A year after the TKA patients completed self-administered questionnaires (SF-36, Womac, FOF, ABC, PASE) and were assessed in physical performance tests (TUG and BBS).Results:There was significant improvement in falls frequency (p<0.001), differentiation of falling status to the benefit of non fallers (p<0.001) and risk of serious injuries (p<0.001). The factors that affected falling status was history of falls (p<0.0005), fear of falls (p<0.017) and advanced age, marginally (p<0.097).Conclusion:TKA generally improved a lot of aspects in patients’ life. One of these was the reduction of fall risk, which always co-exists in this population and can cause devastating problems threatening the benefits of the procedure.

Abstract Background To explore whether previous arthroscopic knee surgery affects future total knee arthroplasty (TKA) results or not. Methods A total of 56 patients with the previous arthroscopic treatment on one knee underwent subsequent bilateral total knee arthroplasty in our hospital from September 2012 to July 2018. Data on each patient were collected in regards to changes in postoperative clinical and functional scores, various other scores, as well as postoperative functional recovery and complications. We defined the knees with a previous arthroscopic history as group A, and the counter side as group B. The Knee Society clinical score, functional scores, range of motion (ROM), finger joint size (FJS), visual analogue scale (VAS) scores were assessed before and after surgery. Using the Kolmogorov-Smirnov Test to test the normality of continuous variables, and the chi-square test to compare the rate of reoperation and complications between two groups. For all statistical comparisons, P < 0.05 was considered significant. Results There were no statistically significance differences found in postoperative Knee Society clinical scores and functional scores between group A and group B, as well as in ROM, FJS, VAS scores and local complications. Conclusion There were no statistically significant differences found in postoperative functional recovery and complications in patients, who underwent total knee arthroplasty with previous knee arthroscopy.
