Abstract

Background  Clinical studies have evaluated a correlation between preoperative walking capacity or function and outcome after hip and knee joint replacement surgery with contradictory results. Our aim was to investigate the effect of preoperative metabolic and/or aerobic exercise on surgical outcome, as well as to evaluate the effect of cumulated exercise by using a cutoff value at 3.5 hours through a systematic review.


Methods  The literature search was performed in Pubmed, Embase, and Cochrane Library databases. The inclusion criteria were randomised controlled trials, full paper publications, describing the preoperative exercise program and reporting outcome data. Exclusion criteria were inadequate randomisation, and unclear interventions or outcomes. The final literature analysis involved 12 studies. The review included meta-analyses on postoperative complications, specifically deep venous thrombosis, and length of stay.


Results  The trials included 616 patients in samples sizing from 20 to 131. The duration of follow-up ranged from 12 to 96 weeks. The preoperative period of training ranged from 4 to 8 weeks; the number and duration of individual sessions varied from 9 to 56 and from 30 to 60 minutes, respectively. All trials reported one or more primary outcome. Meta-analyses were possible for postoperative complications and lengths of stay. Neither development of deep venous thrombosis, odds ratio 0.48 (95% CI 0.18 to1.25) nor the total complication was significantly reduced, 1.08 (0.64 to 1.86). The result for length of stay was –0.22 (-0.86 to 0.42).


Conclusion  This review showed that preoperative exercise had no effect on the surgical outcome, neither overall nor for the cut-off value of 3.5 hours per week.
