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...

Jun-Ho Kim, Hyun-Jung Kim, Dae-Hee Lee
BACKGROUND: Theoretical considerations suggest that leg length increases after opening wedge high tibial osteotomy (HTO) and decreases after closing wedge HTO; however, in vivo studies have yielded conflicting results. This meta-analysis therefore assessed changes in leg length after opening wedge and closing wedge HTO. METHODS: All studies comparing pre- and postoperative leg length in patients who underwent opening and/or closing wedge HTO were included. Two reviewers independently recorded data from each study in terms of sample size as well as preoperative and postoperative leg length of open wedge and/or closed wedge HTO groups...

BACKGROUND: Open wedge high tibial osteotomy (HTO) can influence the tibial slope and thereby the landmarks of currently used patellar height indices. The purpose of this retrospective study was to compare and validate a new femur-referenced patella height measurement method to currently used patellar height indices in a cohort of HTO patients. METHODS: Patellar height (Caton-Deschamps, Blackburne-Peel and Insall-Salvati Indices and our newly developed Femoral Patellar Height Index) as well as tibial slope were analysed...

PURPOSE: There is no information comparing the results of fixed-bearing total knee replacement and mobile-bearing total knee replacement in the same patients previously treated by high tibial osteotomy. The purpose was therefore to compare fixed-bearing and mobile-bearing total knee replacements in patients treated with previous high tibial osteotomy. METHODS: We compared the results of 57 patients with osteoarthritis who had received a fixed-bearing prosthesis after high tibial osteotomy with the results of 41 matched patients who had received a rotating platform after high tibial osteotomy...

AIMS: We aimed to investigate factors related to the technique of medial opening wedge high tibial osteotomy which might predispose to the development of a lateral hinge fracture. PATIENTS AND METHODS: A total of 71 patients with 82 osteotomies were included in the study. Their mean age was 62.9 years (37 to 80). The classification of the type of osteotomy was based on whether it extended beyond the fibular head. The level of the osteotomy was classified according to the height of its endpoint...

J Paul, A H Heitner, M Mauch, A B Imhoff
In the current literature, the rate of return to sports following high tibial osteotomy is high. Patients are largely able to carry out the type of exercise done before the onset of symptoms and are satisfied with the clinical outcome. In general, however, a differentiated view of the sporting ability should be made, and the different requirements of the sport should be considered. A classification according to functional and biomechanical movement analysis seems to advisable. In addition, the recommendations of the treating physician seem to have a high impact on the postoperative level of the sports activities of the patients...

BACKGROUND: There are limited studies regarding the effects of high tibial osteotomy (HTO) on other areas of lower extremity. In current study, we investigated the changes of tibiotalar joint following HTO. METHODS: A total of 39 patients with genu varum requiring HTO were enrolled in this before and after study. The genu varus, joint diversion (JDA), lateral distal tibial (LDTA) and lateral distal tibial-ground surface (LDT-GSA) angles were measured before the operation and compared with 6 months after the surgery...

BACKGROUND: This study aimed to investigate, by means of finite element analysis, the effect of a drill hole at the end of a horizontal osteotomy to reduce the risk of lateral cortex fracture while performing an opening wedge high tibial osteotomy (OWHTO). The question was whether drilling a hole relieves stress and increases the maximum correction angle without fracture of the lateral cortex depending on the ductility of the cortical bone. METHODS: Two different types of osteotomy cuts were considered; one with a drill hole (diameter 5 mm) and the other without the hole...

PURPOSE: To evaluate the clinical and radiological outcomes of open-wedge high tibial osteotomy (OWHTO) with respect to the patellofemoral joint and to assess whether patellofemoral osteoarthritis (OA) progression and alignment changes after OWHTO affect clinical outcomes. METHODS: Inclusion criteria were consecutive patients who underwent OWHTO from March 2005 to September 2013. Exclusion criteria were loss to follow-up within 2 years and absence of second-look arthroscopy findings at the time of plate removal...

OBJECTIVE: The purpose of this study was to evaluate the effects of low-intensity pulsed ultrasound (LIPUS) on bone healing at osteotomy sites after open wedge high tibial osteotomy (OWHTO). MATERIALS AND METHODS: Twenty-six patients underwent OWHTO without bone grafting. Thirty cases treated with LIPUS (group L) after surgery were compared with 13 cases without LIPUS treatment (group C). We divided the osteotomy gap into the lateral hinge and 4 zones on anteroposterior radiography, and the progression of gap filling was evaluated at 1, 3, and 6 months post-operatively in both groups...

OBJECTIVE: Opening Wedge High Tibial Osteotomy (OWHTO) for knee osteoarthritis and for osteonecrosis has reported good results. Use of low intensity pulsed ultrasound (LIPUS) after OWHTO had become an option for the treatment of OWHTO since April 2016. The purpose of this study was to examine whether LIPUS has an accelerating effect on synostosis after OWHTO. MATERIALS AND METHODS: The control subjects were 24 patients with a total of 26 knees (9 male with knees and 15 female with 17 knees treated) treated with OWHTO only...

Partial tibial plateau fractures may occur as a consequence of either valgus or varus trauma combined with a rotational and axial compression component.High-energy trauma may result in a more complex and multi-fragmented fracture pattern, which occurs predominantly in young people. Conversely, a low-energy mechanism may lead to a pure depression fracture in the older population with weaker bone density.Pre-operative classification of these fractures, by Müller AO, Schatzker or novel CT-based methods, helps to understand the fracture pattern and choose the surgical approach and treatment strategy in accordance with estimated bone mineral density and the individual history of each patient...

BACKGROUND: The osseous geometry of the lower limb has a significant impact on knee instability after ligament injuries, and osseous malalignment has been shown to be a significant risk factor for the failure of ligament reconstruction procedures. Therefore, osteotomies around the knee have gained importance as a combined or isolated treatment option in the ligament deficient and malaligned knee. In addition to unloading of an arthritic knee compartment, osteotomies are also performed to protect a reconstructed ligament and to stabilize the joint without ligament surgery...

BACKGROUND: To assess responsiveness of the Japanese Knee Injury and Osteoarthritis Outcome Score (KOOS) and the Oxford Knee Score (OKS) in patients undergoing open-wedge HTO to treat knee osteoarthritis and/or osteonecrosis. METHODS: Patients completed a set of questionnaires before HTO surgery (baseline) and 1 year after surgery. The questionnaires comprised the validated Japanese versions of the KOOS, the OKS, and the SF-36v2 and a visual analogue scale (VAS) for local knee pain and general pain...

INTRODUCTION: A considerable percentage of outliers with under- or over-correction continue to be reported despite precise preoperative planning and cautious intraoperative correction of lower limb alignment in medial opening-wedge high tibial osteotomy (MOWHTO). The purpose of this study was to determine whether our novel technique for the intraoperative adjustment of alignment under valgus stress reduces the number of outliers in patients undergoing MOWHTO compared to the conventional technique, which corrects alignment according to the cable method only...
