background few studies have focused on patients’ characteristics that affects acute kidney injury (aki) after total knee replacement surgery (tkr). objectives the primary objective of this retrospective study was to identify patients’ characteristics associated with aki after tkr. patients and methods between january 2008 and december 2009, 659 patients with a mean age of 67.1 years (range, 39-...

OBJECTIVE The purpose of this study was to compare extensor mechanism function using a sit-to-stand test in patients undergoing uni- and bilateral total knee replacement, with a 6-month follow-up. DESIGN Prospective controlled study. PATIENTS The series included 72 patients with total knee replacement (unilateral 32 patients, bilateral 40 patients). METHODS All patients were evaluated pre...

The stabilised gliding knee prosthesis is a compromise between hinged joints and condylar prostheses. It is a two-piece implant designed to allow normal gliding movements of flexion and extension and which, stabilised by a connecting rod between the femoral and tibial components, allows a designed laxity of rotation and lateral movements. A modification of the original femoral component is desc...

the leading cause of disability in the United States. The prevalence of OA of the knee in various countries can be estimated as 18% of men and women as inferred by a recent meta-analysis. OA can also result in significant direct and indirect costs, which are higher with greater disability. Current therapeutic options for OA are approved to treat the pain associated with the disorder. The Americ...

The concept of a high-performance total knee replacement has gained prominence because of continued technological improvements by implant manufacturers and the changing expectations of an increasingly younger, more active patient population. Improvements in surgical technique, instrumentation, implant design, biomaterials, and implant fixation have occurred in recent years. The literature is in...

The advent of computer-assisted knee replacement surgery has focused interest on the alignment of the components. However, there is confusion at times between the alignment of the limb as a whole and that of the components. The interaction between them is discussed in this article. Alignment is expressed relative to some reference axis or plane and measurements will vary depending on what is se...
