CONTEXT Total hip replacement and total knee replacement are among the most successful and common surgical procedures in orthopaedics. These operations were traditionally reserved for older, sedentary patients. However, these are now being increasingly performed in patients expecting to return to athletic activities. EVIDENCE ACQUISITION The peer-reviewed medical literature was searched via P...

Despite concerted intraoperative attempts to establish equal limb alignment, leg length discrepancy (LLD) remains a frequent complication following elective total hip arthroplasty (THA) [1]. A number of effective intraoperative imaging and clinical limb length techniques have been recommended to minimize this complication; however, all of these assessment modalities have their reported limitati...

temporomandibular joint ankylosis causes limitation in mouth opening and establishes severe deformity and asymmetry in patient’s face, especially in children. surgery is the only treatment. this study was conducted to compare the effect of two surgical approaches, gap arthropasty and interpositional gap arthroplasty, on rate of maximum interincisal opening in temporomandibular joint ankylosis. ...

Recent studies suggest that patients with psychiatric disorders tend to do worse than patients without a psychiatric diagnosis when undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA). Whether this is due to their psychiatric condition, pharmacological treatment, a combination of the two, or something else has not been thoroughly analyzed-and there are no internationally ac...

BACKGROUND An experiment was designed to examine the effects of a decrease in threshold joint position sense (TJPS) at the knee and ankle and of total knee replacement (TKR) on postural control in older adults. It was hypothesized that older adults with a decrease in TJPS and those who had undergone TKR would display increased center of pressure (COP) variance during quiet stance and late onset...

OBJECTIVE Using three risk-adjustment methods we evaluated whether co-morbidity derived from electronic hospital patient data provided significant improvement on age adjustment when predicting major outcomes following an elective total joint replacement (TJR) due to osteoarthritis. METHODS Longitudinal data from 819 elderly men who had had a TJR were integrated with hospital morbidity data (H...

The frequency of lateral unicompartmental knee arthroplasty is estimated at 1% the total volume arthroplasties, according to contemporary literature. Recent studies analyzing this type surgical intervention indicate that when performed with proper indications and technical accuracy, it equally effective safe as arthroplasty. Potential advantages partial replacement include reduced invasiveness ...

PURPOSE The purpose of this paper is to describe the infrastructure of the total joint replacement registry of a large integrated healthcare system's and emphasize challenges associated with orthopedic device classification and evaluation. METHODS Using a large integrated healthcare system innovative infrastructure including electronic health record data, administrative data sources, and regi...

The causes of malalignment in total knee arthroplasty can be categorized into three different groups; 1) Errors in bone cuts 2) Errors in implant fixations, and 3) The method of setting down the cutting guides (1). We would like to announce that more several distal femoral valgus cut errors may occur during total knee replacement.
