WITHDRAWN: Effects of progressive resistance training for early postoperative fast-track total hip or knee arthroplasty: A systematic review and meta-analysis

Abstract

Abstract Introduction Progressive resistance training (PRT) is one of the most commonly used exercise methods after joint replacement, while its effectiveness and safety are still controversial. Therefore, it`s vital to investigate the effect of PRT on muscle strength and functional capacity early postoperative total hip arthroplasty (THA) or total knee arthroplasty (TKA). Method Relevant studies were identified via a search of Medline, Web of science and Cochrane Library from 2002 to 12 May 2020. A meta-analysis was performed to compare postoperative outcomes between PRT and standard rehabilitation (SR) with respect to muscle strength measurement, functional recovery evaluation, and incidence of adverse events. Results fifteen of 704 studies which comprised 7 THAs and 8 TKAs, involving 1,021 adult patients were eligible for inclusion in the meta-analysis. There were no significant differences between the two groups after TKA in the 6-WMT (95% CI= -31.03, -28.70), SCP (95% CI= -1.57, 0.45), Leg extension power (95% CI= -0.06, 0.08), TUG (95% CI= -0.21, 0.23), ST (95% CI= -0.4, 0.91). Similarly, two groups were also no obvious distinction after THA in the 6-WMT (95% CI= -4.39, 109.82), SCP (95% CI= -1.32, 0.82), Leg extension power (95% CI= -0.14, 0.70), ST (95% CI= -5.18, 1.63). There was no difference in the incidence of adverse events. Conclusion PRT early after THA or TKA did not differ significantly from SR in terms of functional capacity, muscle strength recovery and incidence of adverse events. PRT is one of the options for rapid rehabilitation after joint replacement.
