PSI Knee Endoprosthetics

Individual patient-specific instruments for the artificial knee joint

Studies show that the shape of the bone has an influence on the fit of a knee prosthesis. In order to take the individual patient anatomy even more into account in knee joint replacement, the PSI "Patient Specific Instruments" method was developed. 

We use the innovative system of the ZimmerBiomet company, in which patient-specific cutting templates developed according to the latest findings are implanted. Thus, the individual anatomy of the knee joint can be optimally addressed.

Magnetic resonance imaging is used to measure the knee joint and create a "cartilage mapping" as a negative impression of the joint surface. Based on this data, the operation is planned using special software and a plastic template corresponding to the negative impression is created. Intraoperatively, this template guarantees the exact alignment of the necessary bone incisions for implantation of the prosthetic components. 

The PSI technique makes it possible to ensure even more precise alignment and accuracy of fit of your knee prosthesis and, at the same time, to achieve surgical techniques that are soft tissue-friendly while shortening the operation time and optimizing the service life (longevity of the prosthesis).
