Reporting of post-operative rehabilitation interventions for Total knee arthroplasty: a scoping review

ObjectiveThe aim of this study was to evaluate the completeness of reporting of exercise adherence and exercise interventions delivered as part of clinical trials of post-operative total knee replacement (TKA) rehabilitation.Design: Scoping reviewLiterature searchA literature search was conducted in PubMed, EMBASE, AMED, CINAHL, SPORTDiscus and Cochrane Library.Study selection criteriaAll randomized controlled trials (RCT) that examined post-operative exercise-based interventions for total knee arthroplasty were eligible for inclusion. Studies that were multifactorial or contained exercise interventions for both hip and knee arthroplasty were also included.Data synthesisThe definition, type of measurement used and outcome for exercise adherence were collected and analyzed descreptively. Quality of reporting of exercise interventions were assessed using the Consensus for Exercise Reporting Tool (CERT) and the Cochrane Risk of Bias Tool.ResultsThere were a total of 112 RCTs included in this review. The majority of RCTs (63%, n=71) did not report exercise adherence. Only 23% (n=15) of studies provided a definition of adherence. RCTs were of poor quality, with 85% (n=95) of studies having high or unclear risk of bias. Reporting of exercise interventions was poor, with only 4 items (of 19) (21%) of the CERT adequately reported (88-99%), with other items not fulfilled on at least 60% of the RCTs. There were no RCTs that had fulfilled all the criteria for the CERT.ConclusionThe RCTs included in this study poorly reported exercise adherence, as well as description of the post-operative TKA rehabilitation intervention. Future RCTs should use valid and reliable measures of adherence and a proper tool for reporting of exercise interventions (e.g., CERT, TiDER).Pre-registrationOSF:https://osf.io/9ku8a/

Automated summary

The study evaluated the reporting completeness of exercise adherence and interventions in clinical trials of post-operative TKA rehabilitation. A total of 112 RCTs were included, with poor reporting on exercise adherence and interventions. Future RCTs should use valid measures and proper tools for reporting.
