Blood cytokine pattern and clinical outcome in knee arthroplasty patients: comparative analysis 5 years after standard versus "hypoallergenic" surface coated prosthesis implantation.

Background and purpose - Metal sensitivity might provoke complications after arthroplasty. Correspondingly, coated "hypoallergenic" implants are of interest but long-term follow-up data are missing. Thus, we assessed immunological and clinical parameters in such patients.

Total hip arthroplasty: first experiences with pinless THA software to determine leg length and offset.

A rigid body fixation on the proximal femur is required for navigation during total hip arthroplasty. In surgery requiring a small incision, the fixation mechanism (C clamp or screw) may cause soft tissue damage and may force enlargement of the approach. New software available for the OrthoPilot navigation system (B.
