All-polyethylene tibial components are not inferior to metal-backed tibial components in long-term follow-up of knee arthroplasties.

Background: All-polyethylene tibias (APT) are under-utilized in most of the Western countries, due to a shift from the original all-polyethylene design to metal-backed tibia (MBT) components. Only few total knee prostheses allow direct comparison between APT and MBT components, due to different geometric designs in many systems. The Depuy PFC Sigma prostheses have a similar geometric design in both the MBT and the APT, and with the same corresponding femoral component, thus allowing an assessment and comparison between APT and MBT components.

The utility and limitations of the transfibular approach in ankle trauma surgery.

The commonly used extensive approaches to the distal tibia include the posteromedial and anterolateral approaches. The current report describes several cases performed using this technique establishing a rationale and safe zone for performing a transfibular approach to the distal tibia. The advantages of such approach are the excellent visualization of the lateral tibia and the articular space.
