Rehabilitation outcomes following revision for failed unicompartmental knee arthroplasty

BackgroundTo investigate the post-operative outcomes of a revised UKA to a TKA compared to a primary TKA.Methods33 revised UKA were matched to primary TKA and assessed using SF-36, Oxford Knee Scores (OKS) and Knee Society Scores (KSS).ResultsBoth cohorts attained statistically similar SF-36 scores (p > 0.05). KSS improved by 51.12 in rev-UKA and 50.25 in primary TKA (p = 0.977) at 2 years. OKS scores were similar at 6 months (p = 0.094) and 2 years (p = 0.235)..InterpretationRevision of UKA does not require a longer period of rehabilitation to achieve satisfactory return to function.
