ATRO Medical

A solution for post meniscectomy pain

ATRO Medical was founded by Dr. Tony van Tienen in 2016. When Van Tienen was working as an orthopedic knee surgeon, he encountered many patients who were suffering severe knee pain after a meniscus removal but were too young for a knee replacement. And their knee cartilage was actually too good to be replaced by metal and plastic. There was no fitting solution available, and as a result, these people experienced long episodes of pain.

ATRO Medical started as a spin-off from Radboudumc and DSM. After many years of academic research, these two parties decided assist van Tienen in launching a company to let the dream of an artificial meniscus come true.
