“…Giffin et al 16 showed that increasing the posterior tibial slope with an osteotomy resulted in a decrease in posterior tibial sag and translation by almost 50% at 90 degrees of knee flexion in cadavers with sectioned PCLs. Petrigliano et al 17 showed that decreasing the tibial slope with an osteotomy or making the slope more anterior (as seen in achondroplasts), resulted in a significantly increased posterior tibial translation and dynamic knee instability in patients with PCL and/or posterolateral corner injuries. We are unsure if the overall lower prevalence of PCL injuries compared with ACL injuries contributes to the lack of PCL injuries seen in our study, even though the achondroplasts' more anterior slope would possibly predispose them to these injuries.…”

“…The posterior stability and the range of the knee are reduced consequently. [13] In addition, the HE of the knee due to the slope reduction increases the load of the anterior part of the tibial plateau, which might speed up osteoarthritis progression. What is more, the secondary deformity and osteoarthritis of the ankle could not be ignored in this patient and this can be explained by the compensatory mechanism of the gait.…”

Rationale:High tibial osteotomy (HTO) has been used widely for medial compartment knee osteoarthritis to correct the deformity and relieve symptoms, especially in young patients who are willing to maintain the high activity level. However, the change of bone morphology, ligament imbalance, limb malalignment, and other complications may influence the short-term outcomes of HTO. Some cases may even require conversion to TKA shortly after HTO because of the loss of correction or pain due to accelerated osteoarthritis.Patient concerns:A 43-year-old female patient presented with persistent pain of both the left knee and the ankle. She underwent a lateral closing wedge HTO two years ago. Radiographies showed The Kellgren-Lawrence (K-L) grade IV osteoarthritic change and hyperextension (HE) of the left knee and the degeneration of the left ankle.Diagnoses:A failed lateral closing wedge high tibial osteotomy with knee hyperextension and secondary ankle degeneration.Intervention:A posterior-stabilized TKA conversion and postoperative rehabilitation were performed.Outcomes:The operation corrected the HE deformity and relieved the pain at the level of the left knee. However, the secondary change of the left ankle was irreversible.Lessons:A failed lateral closing wedge HTO might speed up the degeneration of the knee and increase extra technical issues in the following TKA. What is more, the secondary osteoarthritis and deformity of the ankle cannot be ignored.

“…High tibial osteotomy (HTO) is an alternative to total knee arthroplasty (TKA) that is routinely used to treat moderate osteoarthritis (OA) localized to one compartment of the knee, especially in young, active patients who meet the criteria for undergoing the procedure . With an HTO, the surgeon aims to change the coronal alignment of the leg in order to shift the center of force passing axially through the knee from the arthritic region of the knee towards the unaffected side …”

Objectives:To develop an accurate intraoperative method to estimate changes in intraarticular contact pressures during high tibial osteotomy (HTO). Methods:Changes in knee alignment and pressure were monitored in real time in seven cadaver specimens that received HTO. Intraarticular contact pressure (N/mm 2 ) in each knee compartment was estimated based on extraarticularly acquired data (leg alignment, correction, and ankle tilt) and based on the application of an axial force of half bodyweight (400-450 N).Results: Contact pressure estimation was more accurate in the lateral compartment (R 2 = 0.940) than in the medial compartment of the knee (R 2 = 0.835). The optimismcorrected R 2 was 0.936 for the lateral compartment and 0.821 for the medial compartment. Conclusions:We have established a framework for estimating the change in intraarticular contact pressures based on extraarticular data. This research could be helpful in generating appropriate algorithms to estimate joint alignment changes based on applied loads.
