Outcome measures in prehabilitation interventions for total hip and knee arthroplasty: A scoping review.

The review only included English-language randomised controlled trials, which may miss relevant studies from non-English speaking countries or other designs. Methodological quality of the included trials was not assessed, as is standard for scoping reviews, so the reliability of the reported outcomes is unknown. The alignment analysis assumed full instrument use unless stated otherwise, which may overestimate domain coverage. The search was updated in May 2025, but rapid changes in prehabilitation research mean some very recent trials may not be included.

The authors received no financial support for the research. Professor Denehy has received support for educational presentations on prehabilitation from Roche and Bristol Myers Squibb. All other authors declared no conflicts of interest.

Do not interpret the high frequency of patient-reported outcomes and length of stay as evidence that these are the most valid or clinically meaningful measures. They are simply the most commonly collected, and the review explicitly states that alignment with recommended core domains is poor, meaning important outcomes like satisfaction and cost are largely missing from the evidence base.
