- Patient-individual TKA with individualized trochlear design showed superior early patient-reported outcomes compared to robotic-assisted TKA with off-the-shelf implants in severe valgus knee phenotypes.
- Both groups had comparable preoperative valgus deformity, but at 3 and 12 months, the patient-individual TKA group had significantly better scores in all PROMs (FJS, Kujala, OKS, WOMAC).
- The largest difference was in the Kujala score at 12 months (79.5 vs. 59.7), indicating better patellofemoral function with patient-individual implants.
- FJS improved more rapidly in the patient-individual TKA group, suggesting faster joint awareness recovery.
- One revision occurred in the patient-individual TKA cohort due to suspected infection, with no revisions in the robotic-assisted group.
- The study followed restricted kinematic alignment principles with valgus undercorrection, and individualized trochlear orientation may enhance patellofemoral mechanics and recovery.
