Revision of partial knee to total knee arthroplasty with use of patient-specific instruments results in acceptable femoral rotation.
Patient-specific instruments (PSI) were initially developed for the alignment of both total knee- (TKA) and partial knee arthroplasty (PKA). We hypothesize that CT-based PSI for PKA-to-TKA revision surgery can restore biomechanical limb alignment and prosthetic component positioning in vivo as calculated pre-operatively, resulting in a limited percentages of outliers. ⋯ Prospective cohort study, Level II.
