Five-Year Outcomes of UKA Versus TKA in Elderly Patients With Severe Varus Deformity in Knee Osteoarthritis: The Modifying Effect of Preoperative Extensor Muscle Radiomics Quality
In elderly patients with severe varus knee osteoarthritis, unicompartmental knee arthroplasty (UKA) demonstrates comparable five-year clinical outcomes to total knee arthroplasty (TKA) with reduced surgical trauma and faster early recovery, although the early functional advantage of UKA is attenuated in patients with poorer preoperative extensor muscle quality as quantified by radiomics.
