We have with great interest read the recent meta-analysis ‘Is it necessary to perform prehabilitation exercise for patients undergoing total knee arthroplasty: meta-analysis of randomized controlled trials’ published in The Physician and Sportsmedicine [Citation1]. However, we are concerned that the analyses may have included a trial that did not investigate pre-habilitation.
The included study ‘Jakobsen et al. 2014’ listed in Table 1 and included in several of the meta-analyses in the systematic review by Chen et al. 2018 is not to be found in the list of references [Citation1]. As we read the characteristics of ‘Jakobsen et al. 2014’ outlined in Table 2, the study is likely the trial entitled ‘Early progressive strength training to enhance recovery after fast-track total knee arthroplasty: a randomized controlled trial’ [Citation2], which we published in 2014. However, our study investigated post-operative rehabilitation [Citation2], which is why it is hard to understand why it is included in a meta-analysis investigating the effectiveness of exercise prior to surgery (pre-habilitation).
We may be mistaken, but could the authors please help explain?
