OBJECTIVE To determine the influence of the pre-operative cognitive impairment on results of the total knee arthroplasty according to a doctor and patient perspective. MATERIAL AND METHOD A prospective study was conducted on patient from the surgical waiting list who had undergone a primary total knee arthroplasty. The sample initially included 265 patients, but 50 were subsequently excluded....

BACKGROUND AND PURPOSE Prosthetic joint infections can be caused by bacteria derived from the patient's skin. The aim of the study was: (1) to determine which bacteria colonize the nose and groin in patients planned for primary hip or knee arthroplasty, (2) to determine the antimicrobial resistance patterns, and (3) to monitor changes in bacterial colonization and resistance patterns connected ...

We have reviewed nine patients with Parkinson's disease who had 12 primary total knee arthroplasties and one revision. Deformities were corrected by conventional techniques and semi-constrained resurfacing arthroplasties were used. Follow-up ranged from two to eight years (average 4.3 years). Nine of the 12 primary arthroplasties were rated as excellent by the Hospital for Special Surgery knee ...

BACKGROUND Whether total knee arthroplasty with use of computer-assisted surgical navigation can improve the limb and component alignment is a matter of debate. We hypothesized that total knee arthroplasty with use of computer-assisted surgical navigation is superior to conventional total knee arthroplasty with regard to the precision of implant positioning. METHODS Sequential simultaneous bi...

Arthroplasty entails considerable exposure to allogenic blood transfusion. Cell salvage with washing is a contemporary strategy that is not universally used despite considerable potential benefits. We searched Embase and Medline to determine if blood salvage with washing during primary and/or revision hip and knee arthroplasty results in lower rates of transfusion and postoperative complication...

The aim of this review article is to analyze the results of high tibial osteotomy compared to unicompartmental knee arthroplasty in patients with unicompartmental knee osteoarthritis. The search engine used was PubMed. The keywords were: "high tibial osteotomy versus unicompartmental knee arthroplasty". Twenty-one articles were found on 28 February 2015, but only eighteen were selected and revi...

BACKGROUND Venous thromboembolic events, either deep venous thrombosis or pulmonary embolism, are important complications in patients undergoing knee or hip arthroplasty. The purpose of this study was to evaluate the effectiveness of a mobile compression device (ActiveCare+S.F.T.) with or without aspirin compared with current pharmacological protocols for prophylaxis against venous thromboembol...

BACKGROUND Highly active antiretroviral therapy has prolonged the lifespan of individuals infected with human immunodeficiency virus (HIV). We hypothesized that the number of primary total joint arthroplasties performed in this population has been increasing and that HIV infection is not an independent risk factor for postoperative complications. METHODS The Nationwide Inpatient Sample for th...

OBJECTIVE To examine whether total joint arthroplasty of the hip and knee reduces the risk for serious cardiovascular events in patients with moderate-severe osteoarthritis. DESIGN Propensity score matched landmark analysis. SETTING Ontario, Canada. PARTICIPANTS 2200 adults with hip or knee osteoarthritis aged 55 or more at recruitment (1996-98) and followed prospectively until death or 2...

BACKGROUND The underuse of total joint arthroplasty in appropriate candidates is more than 3 times greater among women than among men. When surveyed, physicians report that the patient's sex has no effect on their decision-making; however, what occurs in clinical practice may be different. The purpose of our study was to determine whether patients' sex affects physicians' decisions to refer a p...
