“…Proximal tibial osteotomy is an appropriate surgical treatment for preventing the medial compartment osteoarthritis of knee (10). Some studies have shown that patients managed with high tibial osteotomy reported satisfactory outcomes (knee society score > 80) after a mean follow-up of 8 years (11).…”

Background: Genovarum is the most common knee deformity for which a variety of surgical techniques have been proposed. Objectives: We decided to share our experiences through a detailed presentation of a new and simple method called proximal tibia osteotomy using M-W method. Methods: In this study, 68 patients (128 knees) with proximal tibia osteotomy with an average age of 34 years, who had undergone W-M osteotomy surgery in a community hospital during 2001 and 2014, were studied using knee society score (KSS) and functional KSS questionnaires, and their clinical results were analyzed. Results: No significant difference was obtained between patients undergoing surgery by this method in KSS before (78.8) and after (89.6) the surgery. Although the mean score was improved, functional KSS improved significantly after surgery. None of the patients had peroneal nerve complication, infection, osteomyelitis, or postoperative nonunion. Moreover, no recurrence was detected in a mean of 2.7 years follow-up. Conclusions: Considering the advantages of this method, it is recommended that knee varus deformity be treated using this method, as its rate of complications is low. However, further studies should be conducted on the effectiveness of this method in the future.

“…It is believed that the varus or valgus deformity of the lower extremity is highly associated with osteoarthritis, especially the knee joint. [1][2][3][4] Previous study demonstrated that the knee joint alignment and kinematics was altered in patients with early knee ostoearthritis. [5] Patient with varus knee often had a varus inclined tibia, which could subsequently alter normal biomechanics of the ankle joint.…”

Background : Varus malalignment of the tibia could alter ankle biomechanics, and might lead to degenerative changes of the ankle joint. However, previous studies failed to report the detailed changes of ankle biomechanics in varus malalignment of the tibia. The aim of this biomechanical study was to evaluate how the ankle joint pressure would change in response to the incremental increases in varus malalignment of the tibia. Methods 8 fresh-frozen human cadaver legs were tested in this study. Varus malalignment of the tibia and a total of 600N compressive force was simulated using a custom made fixture. Intra-articular sensors (TeckScan) were inserted in the ankle joint to collect the ankle joint pressure data. The testing sequence was 0°, 2°,4°,6°,8°,10°,12°,14°,16°,18°,20° of tibial varus. Results As the tibial varus progressed, the center of force (COF) shifted laterally both for the medial and lateral aspect of the ankle joint. For the medial aspect of the ankle joint, the lateral shift reached its maximum at 8º [2.76 (1.62) mm, p=0.002] of tibial varus, while for the lateral aspect of the ankle joint, the lateral shift reached its maximum at 12º [2.11 (1.19) mm, p=0.002] of tibial varus. Thereafter, the COF shifted medially as the tibial varus progressed. For the lateral aspect of the ankle joint, The P mean increased from 2103.8 (625.1) kPa at 0º to 2295.3 (589.7) kPa at 8º of tibial varus (p=0.047) , significant difference was found between the P mean at 0º and 8º (p=0.047) of tibial varus. Then as the tibial varus progressed, the P mean decreased to 1748.9 (467.2) kPa at 20º of tibial varus (p=0.002) . The lateral joint pressure ratio also increased from 0.481 (0.125) at 0º to 0.548 (0.108) at 10º of tibial varus (p=0.002) , then decreased to 0.517 (0.101) at 20º of tibial varus (p=0.002) . Conclusions For mild tibial varus deformities, there was a lateral shift of COF and lateral stress concentration within the ankle joint. However, as the tibial varus progressed, the COF shifted medially and the lateral stress concentration decreased.
