PURPOSE: To assess whether the combination of HTO and cartilage treatment produced an additional clinical benefit compared to HTO alone. The secondary aim was to identify if there was any difference among different cartilage procedures in terms of healing potential and clinical outcome. METHODS: A systematic review of the literature was performed on PubMed database by three independent observers according to the following inclusion criteria: clinical reports of any level of evidence, written in the English language, with no time limitation, about HTO associated with cartilage surgical and injective treatment, including surveys reporting clinical, radiological, or second-look outcomes at any follow-up time...

High tibial osteotomy (HTO) is a well established technique for the treatment of medial osteoarthritis of the knee with varus malalignment. The outcome of total knee arthroplasty (TKA) after HTO remains uncertain. The aim of this paper is to revise the literature with the aim of answering the following question: Does a previous (HTO) influence the long-term function or survival of a TKA?. The search engine was MedLine. The keywords used were: total knee arthroplasty after high tibial osteotomy. One hundred and ten articles were found...

High tibial osteotomy (HTO) is a valid treatment option for young active patients with medial tibiofemoral osteoarthrosis (OA) and varus deformity. Sometimes medial OA is combined with symptomatic anterior cruciate ligament (ACL) deficiency. Although isolated HTO (with possible delayed ACL reconstruction) might be indicated in the older population, young active patients may require combined HTO and ACL reconstruction. In addition, an abnormally increased tibial slope may predispose to ACL reconstruction failure and should be addressed for a successful ACL revision...

BACKGROUND: High tibial osteotomy (HTO) re-aligns the weight-bearing axis (WBA) of the lower limb. The surgery reduces medial load (reducing pain and slowing progression of cartilage damage) while avoiding overloading the lateral compartment. The optimal correction has not been established. This study investigated how different WBA re-alignments affected load distribution in the knee, to consider the optimal post-surgery re-alignment. METHODS: We collected motion analysis and seven Tesla MRI data from three healthy subjects, and combined this data to create sets of subject-specific finite element models (total=45 models)...

PURPOSE: Opening wedge high tibial osteotomy (HTO) as a treatment in unicompartimental osteoarthritis of the knee can significantly relieve pain and prevent or at least delay an early joint replacement. The fixation of the osteotomy has undergone development and refinements during the last years. The angle-stable plate fixator is currently one of the most commonly used plates in HTOs. The angular stable fixation between screws and the plate offers a high primary stability to retain the correction with early weight-bearing protocols...

BACKGROUND: Both high tibial osteotomy (HTO) and unicompartmental knee arthroplasty (UKA) are well-established treatments for medial knee osteoarthritis (OA). However, it is unclear whether HTO or UKA leads to better clinical outcomes and lower complication rates. This meta-analysis compared the clinical outcomes and complications of HTO and UKA in patients with medial knee OA. METHODS: All studies comparing the functional outcome, postoperative pain, revision rate to total knee arthroplasty (TKA), postoperative complications, postoperative velocity, and postoperative range of motion (ROM) as assessed with various measurement tools in patients with medial knee OA treated with HTO or UKA were included...

High tibial osteotomy (HTO) is a useful alternative in the treatment of symptomatic varus malalignment. However, among its drawbacks is the tendency to decrease patellar height and increase the posterior tibial slope. The increased tibial slope increases anterior cruciate ligament tension and may compromise its function. On the other hand, patella baja often causes anterior knee pain and, over time, may favor degeneration of the patellofemoral joint. The aim of this study is to describe a technical modification of the standard open-wedge HTO...

BACKGROUND: Biomechanical gait changes are proposed as adaptations to medial knee osteoarthritis (OA), and little is known about which parameters can be modified early by high tibial osteotomy (HTO) surgery. The aim of this study was to identify early gait changes in a postoperative period of 6 months as compared to a control group, in three different spatial planes. METHODS: Twenty-one patients with OA were submitted to three-dimensional gait analysis preoperatively and 6 months after HTO surgery...

BACKGROUND: Prior studies have compared unicompartmental knee arthroplasty (UKA) with high tibial osteotomy (HTO) suggesting that both procedures had good clinical outcomes. However, which treatment is more beneficial for unicompartmental knee osteoarthritis is still a controversy. The purpose of our study is to obtain postoperative outcomes of revision rate, complications, function results, range of motion (ROM), and pain between the 2 procedures. METHODS: Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were followed and study protocol was published online at PROSPERO under registration number CRD42016049316...

In this paper, a series of NiAl hydrotalcite-like compounds (HTLCs) were prepared by the urea-decomposition method. Removal of carbonyl sulfide (COS) and methyl mercaptan (CH4S) over the hydrotalcite-derived oxides (HTO) at low temperature was studied. The Ni3Al-HTO exhibited higher catalytic activities than Ni3Al mixed oxides prepared by physical mixing method (Ni3Al-PM) or impregnation/calcination method (Ni3Al-IC). Based on the characterization, it was found that desulfurization activities are closely tied to the surface acid-base properties of catalysts...

Heterotopic ossification (HTO) is the dystrophic formation of mature lamellar bone outside the confines of normal osseous tissues. It is frequently a complication which occurs following traumatic insult, both iatrogenic and non-iatrogenic, and neurological compromise. While mild degree of disease is often asymptomatic, significant pain and mobility limitations may result in reduced quality of life in advanced cases. Currently, the commonly accepted management for patients experiencing significant symptomatic HTOs is a combination therapy of surgical excision with prophylactic radiotherapy in the immediate perioperative period...
