The assessment of intraoperative prosthetic knee range of motion using two methods.

The commonly used standard goniometer has been shown to underestimate knee flexion. Computer-assisted navigation for total knee arthroplasty offers itself as an alternative method to quantify knee flexion. The goal of our study was to determine the reliability of each instrument in measuring intraoperative range of motion during total knee arthroplasty.

Proximal femoral replacement in patients with non-neoplastic conditions.

Background: Numerous factors may give rise to the loss of femoral bone stock that can be encountered in revision hip arthroplasty. Proximal femoral replacement is an option for the treatment of severe proximal femoral bone loss. In this study, we sought to determine the outcome of reconstructive surgery with the use of a modular proximal femoral replacement (a so-called megaprosthesis) in patients with proximal femoral bone loss due to non-neoplastic conditions.
