OBJECTIVE: To report prospective results of total knee arthroplasty (TKA) for valgus knees. METHODS: 120 women and 19 men aged 40 to 85 (mean, 75) years with valgus knees underwent primary TKA. Of the 219 knees, 143, 67, and 9 had type-I, type-II, and type-III valgus deformities, respectively. A preliminary lateral soft-tissue release was performed, and the tibia and femur were prepared. The tight lateral structures were released using the pie-crusting technique. In 93% of the knees, cruciate substituting implants were used. In knees with severe deformity and medial collateral ligament insufficiency, the posterior cruciate ligament was sacrificed and constrained implants were used. The Hospital for Special Surgery (HSS) knee score was assessed. RESULTS: Patients were followed up for 6 months to 5 years. All knees were clinically stable in both mediolateral and anteroposterior planes. No radiolucency was noted. The mean modified HSS knee score improved from 48 to 91.
