Mid-term clinical outcomes and isokinetic performance after primary total knee arthroplasty within a modified ERAS protocol: a single-blinded randomized controlled trial

Background

Persistent muscular deficits are a major contributor to functional limitations following total knee arthroplasty (TKA). While Enhanced Recovery After Surgery (ERAS) protocols are increasingly adopted to improve postoperative outcomes, their influence on mid-term objective muscle strength recovery remains insufficiently defined. This study aimed first, to determine whether a modified ERAS protocol enhances mid-term recovery of knee muscle strength after primary TKA and second, compare associated clinical outcomes using validated functional and patient-reported measures.
