The Trammpolin® meniscus prosthesis is an anatomically shaped, non-biodegradable polymer implant designed to mimic the function of the natural medial meniscus by functioning as a shock absorber within the knee joint. The Trammpolin® meniscus prosthesis is implanted by an arthroscopic procedure with a specific surgical instrument set to determine correct meniscus prosthesis size and facilitate proper placement of the meniscus prosthesis with fixation screws.

 
This procedure is intended for people between 30-65 years of age with persistent knee pain in the medial compartment, who underwent a meniscectomy more than 6 months ago. In addition, patients have limited cartilage damage (grade IV modified Outerbridge scale) and a nearly straight leg axis. For a complete set of inclusion/exclusion criteria of the ongoing clinical study (AIR study), see the study registered at ClinicalTrials.gov under number NCT03696836 

If a patient meets these criteria and would like to participate in this study, you can refer the patient to your colleague orthopedists at the participating centers in the AIR-study: Radboudumc and the Sint Maartenskliniek in Nijmegen and Maastricht UMC+ by reference of "Potential candidate for AIR study Trammpolin".
