Pre-surgery exercise and post-operative physical function of people undergoing knee replacement surgery: A systematic review and meta-analysis of randomized controlled trials
(Foundation for Rehabilitation Inofrmation, 2017-03-29) Peer, Maria; Rush, Robert; Gallacher, P.; Gleeson, Nigel
Objective: To summarize the evidence regarding the effectiveness and dose-response characteristics of pre-operative exercise programmes on post-operative physical function following total knee arthroplasty. Data sources: CINAHL, Cochrane Library, PubMed, SPORTDiscus and EMBASE. Study selection: Randomized controlled trials were eligible if they provided full description of physiological stress (i.e. mode, frequency, intensity and duration). Data extraction: Data extraction and evaluation were performed by one reviewer. Methodological quality of the selected studies was assessed using the Physiotherapy Evidence Database scale. Data synthesis: Twelve candidate studies were identified, but only 3 papers satisfied all inclusion criteria: 2 studies evaluated the effect of resistance training and 1 trial investigated proprioceptive training. The latter study elicited significantly enhanced post-operative gains in function for indices of standing balance (overall stability index: Hedges' g = -1; anteroposterior stability index: Hedges' g = -1.15; 6 weeks post-surgery). Results of meta-analysis based on the findings of 2 studies showed that, compared with controls, prehabilitative exercise involving resistance training offered no additional gains in isometric quadriceps muscle strength at 6 and 12 weeks post-operatively. Conclusion: Despite a potential for efficacy of exercise-based conditioning, this review highlights the scarcity of robust dose-response evidence to guide the formulation of total knee arthroplasty prehabilitation effectively.
