Objective: Our study aimed to evaluate the outcomes of knee arthrodesis with external fixation in patients undergoing revision surgery due to an infection following knee arthroplasty. Method: The mean age of the patients recruited in the study was 71.1 years (range: 58-84). Of the 40 patients who underwent revision total knee arthroplasty between 2010 and 2014, nine patients developed recurrent...

INTRODUCTION Knee arthrodesis may be the last possible option for infected total knee arthroplasty (TKA) patients and in revision cases involving severe bone loss and/or extensor mechanism damages. Success in these situations depends on achieving good fixation assembly stability. We report bone fusion results using a fixation technique combining cross-pinning by two Steinman pins with a single-...

BACKGROUND The incidence and prevalence of knee arthrodesis (fusion) in the United States is largely unknown, in spite of numerous case reports and review articles that have called attention to this life altering procedure. PURPOSE This study was conducted to determine long-term knee arthrodesis incidence and patient populations, and to characterize the associated healthcare burden. METHODS...

Solid bony fusion of large joints affected with active chronic infections, is still the most effective surgical solution to establish a useful function of the affected limb. Even with extensive peri-articular bone loss and severe deformities, arthrodesis in a functional position can provide effective stability. The reported fusion rates in such patients are not encouraging however, and secondar...

objectives: patients suffering from mild to moderate knee osteoarthritis may be treated with unloader knee orthoses or laterally wedged insoles. the aim of this study was to identify and compare the effects of two orthoses in these patients. methods: 56 patients with medial compartment knee oa were evaluated when wearing an unloader knee orthosis and insoles with a 6° lateral wedge which were r...

the fusion of medical images is very useful for clinical application. generally, the pet image indicates the function of tissue and the mri image shows the anatomy of tissue. in this article we fused mri and pet images and the purpose is adding structural information from mri to pet image. the images decomposed with curvelet transform, and then two images fused with applying fusion rules. we us...

tuberculosis (tb), once a disease confined to undeveloped or developing nations is currently in resurgence, which is attributable to pandemic human immunodeficiency virus (hiv) infection and immigration from endemic areas. tuberculous arthritis is difficult to diagnose early because of its atypical insidious clinical manifestations and nonspecific imaging findings. tb is also known as the ‘grea...

background : biomechanical factors are known to be important in knee osteoarthritis (oa) development and progression. this study was designed to determine changes of hamstrings muscle activation, knee adduction moment and ankle rotation angle in two knee osteoarthritis (mild and moderate) and a healthy control group.   methods: 16 females (10 with mild and 6 with moderate medial knee osteoarthr...

Arthrodesis is usually performed with joint resection or at least with removal of cartilage. Our recent experience with successful fusion in all 11 rheumatoid ankles treated only with percutaneous fixation questions the necessity of debridement of the joint before arthrodesis. In this rabbit study we tested the hypothesis that joints fuse because of rigid fixation. 9 skeletally mature loop-ear ...

a generalization of the known results in fusion frames and $g$-frames theory to continuous fusion frames which defined by m. h. faroughi and r. ahmadi, is presented in this study. continuous resolution of the identity (cri) is introduced, a new family of cri is constructed, and a number of reconstruction formulas are obtained. also, new results are given on the duality of continuous fusion fram...
