Abstract

Background: Total knee arthroplasty (TKA) for valgus knee deformities presents significant surgical challenges due to soft-tissue imbalance, lateral contractures, and medial insufficiency. This study aimed to compare clinical and radiological outcomes of three surgical techniques : medial parapatellar with lateral release, lateral parapatellar, and robotic-assisted TKA.


Methods: In this prospective cohort study, 138 knees from 120 patients with valgus deformity ≥10° were enrolled between January 2017 and December 2022. Patients were randomized into three intervention groups: Group A (medial approach with lateral release), Group B (lateral approach), and Group C (robotic-assisted TKA). Outcomes included intraoperative parameters, functional recovery (Knee Society Score [KSS], Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC], Visual Analog Scale [VAS]), range of motion, radiographic alignment, and complication rates, evaluated over a 24-month follow-up.


Results: All groups showed significant postoperative improvement. Group C demonstrated the highest mean KSS (89.4 ± 5.8), lowest WOMAC score (11.8 ± 3.6), and greatest VAS reduction (2.1 ± 0.7; p < 0.01). Robotic TKA achieved superior mechanical axis restoration (mean HKA angle 0.8° ± 1.1°) and avoided formal soft-tissue releases. Complication rates were low and comparable across all groups, and implant survivorship was 100% at 24 months.


Conclusion: Robotic-assisted TKA offers enhanced functional recovery, optimal alignment, and lower surgical trauma in valgus knees, particularly in severe deformities. It provides a reliable, reproducible solution with favorable mid-term outcomes, supporting its broader adoption in complex arthroplasty settings.
