Background: The maintenance of deformity in the ankle and hindfoot after correction of knee deformity following kneearthroplasty may cause abnormal tension in the knee and patient dissatisfaction. The aim of this study was to determinethe effect of knee arthroplasty on the hindfoot alignment in patients with severe genu varum and valgum.Methods: A total of 84 patients with pri...

Osteoarthritic (OA) knees with severe extension varus deformity seem to have correspondingly more severe flexion varus, especially beyond a certain tibiofemoral angle. Clinical measurement of flexion varus and fixed flexion deformity (FFD), which had been difficult to perform because of the spatial alignment of the knee in flexion, was recently made possible with computer navigation. We conduct...

background: this is to assess one of the rare complications after total knee replacement and to assess risk factors of failure.methods: 11 patients with varus knee and an average age of 67 years underwent tka between 2005 and 2013. all patients returned with a sudden sharp knee pain, disability to walk and significant decrease in rom about 4 to 8 weeks after surgery. radiographic examination re...

Patients with severe varus deformity of the knee (≥15° varus) usually are not considered good candidates for minimally invasive total knee arthroplasty (TKA). The goal of this study was to retrospectively investigate outcomes in patients with severe varus deformity after minimally invasive TKA. A study group of 52 patients with a tibiofemoral mechanical axis of 195° or greater was compared with...

Introduction: The most common cause of ankle osteoarthritis (OA) is posttraumatic, with around 80% of all cases, followed by primary and secondary ankle OA. Patients often present wit asymmetric involvement of the tibiotalar joint, resulting in valgus or varus deformity of the ankle and hindfoot. The etiology of asymmetric arthritic ankles can be divided into 2 main etiologic and morphologic gr...

BACKGROUND There have been conflicting studies published regarding the ability of various total knee arthroplasty (TKA) techniques to correct preoperative deformity. The purpose of this study was to compare the postoperative radiographic alignment in patients with severe preoperative coronal deformity (≥10° varus/valgus) who underwent three different TKA techniques; manual instrumentation (MAN)...

diagnosis of knee osteoarthritis can be confirmed based on clinical and/or radiological features. the potential of a progressive disease can be prevented or decreased by earlier recognition and correction of associated factors. obesity and alignment especially varus malalignment are recognized factors of a progressive disease. both nonpharmalogical as well as pharmacological modalities of treat...

primary knee osteoarthritis (oa) is one of the degenerative diseases that destroy auricular cartilage within knee joint and cause pain, varies deformity, decrease knee function. total knee arthroplasty (tka) is an effective intervention in order to relieve pain, improve function and qol (quality of life) in patients with severe osteoarthritis of the knees that have different degrees of varus de...

A consecutive series of 23 patients (25 ankles) with osteoarthritis of the ankle and severe varus or valgus deformity were treated by open arthrodesis using compression screws. Primary union was achieved in 24 ankles one required further surgery to obtain a solid fusion. The high level of satisfaction in this group of patients reinforces the view that open arthrodesis, as opposed to ankle repla...

Our study describes the clinical outcome of total ankle replacement (TAR) performed in patients with moderate to severe varus deformity. Between September 2004 and September 2007, 23 ankles with a varus deformity > or = 10 degrees and 22 with neutral alignment received a TAR. Following specific algorithms according to joint congruency, the varus ankles were managed by various additional procedu...
