The impact of extreme genu varum and genu valgum on postoperative outcomes using mini-subvastus approach in TKA
Abstract Increasing interest in using minimally invasive approaches in TKA has led to the question: how much deformity is accepted for using MIS in TKA? A single surgeon performed 87 consecutive TKAs with mini-subvastus approach, using unconstrained prosthesis in 84 knees and constrained prosthesis in 3 knees. We conducted a prospective study in which patients were divided into two groups according to preoperative tibiofemoral axes (TFM), one group with 160°
