PurposeThe purpose of this study was to compare the clinical and radiographic outcomes of opening- and closing-wedge valgus high tibial osteotomy (HTO) for the treatment of medial unicompartmental knee osteoarthritis with a minimum follow-up of 3 years, with a focus on patellofemoral alignment and anterior knee pain.MethodsWe performed a retrospective comparison of 50 patients who underwent closing-wedge HTO and 50 patients who underwent opening-wedge HTO for isolated medial joint arthritis of the knee with varus deformity. All patients were evaluated and the 2 study groups were compared after a minimum follow-up of 3 years with a focus on patellofemoral alignment, patellofemoral osteoarthritis, and anterior knee pain while climbing stairs.ResultsPatellar alignment (patellar tilt and lateral patellar displacement) was not significantly different in the 2 groups either preoperatively or at follow-up. Furthermore, there were no significant differences in the extent of patellofemoral arthritis and incidence of anterior knee pain at follow-up between the 2 groups. In addition, no significant intergroup difference was found in terms of the incidence of anterior knee pain (28% in closing-wedge group and 32% in opening-wedge group at follow-up).ConclusionsThe results of closing- and opening-wedge valgus HTO were not found to be significantly different with respect to patellar alignment, osteoarthritis of the patellofemoral joint, or anterior knee pain.Level of EvidenceLevel III, retrospective comparative study.
