Meniscus Injury

Meniscus injury can be severely debilitating and may lead to osteoarthritis and the need for knee arthroplasty. Today’s treatment options are very limited resulting in a high unmet need. Partial replacement is only suitable as long as the meniscal rim is intact. Allograft transplantation has limitations including low donor availability.


ATRO medical


ATRO Medical is a spin-off company from the Radboudumc and DSM Biomedical and develops the Trammpolin® meniscus prosthesis. Meniscus damage and wear are important causes of osteoarthritis of the knee. The Trammpolin® meniscus prosthesis intends to replace the damaged meniscus, with the aim of restoring the protective function of the meniscus by acting as a joint spacer. The company is addressing a large unmet medical need, as an increasing number of patients with knee injuries undergo meniscectomy (partial or total removal of the meniscus). These patients gradually develop osteoarthritis, resulting in pain and reduced mobility. Current treatment options for these patients are limited and have poor outcomes. Trammpolin® meniscus prosthesis aims to provide a cost-­effective solution to reduce pain and restore mobility.
