Trammpolin meniscus prosthesis study

The Trammpolin® meniscus prosthesis is an investigational implant designed for patients who suffer from persistent knee pain at the medial side of the knee, which is caused by partial or sub-total meniscectomy. 


ATRO Medical is conducting their first clinical study (AIR study) to investigate whether the Trammpolin® meniscus prosthesis is safe and provides pain relief to the medial side of the knee where meniscal tissue had previously been removed. The clinical study is initiated in October 2018 and is currently enrolling 18 patients at select medical centers in the Netherlands. The clinical study is approved by the Dutch government (Dutch Health and Youth Care Inspectorate) and Medical Research Ethics Committee.


Currently we are looking for candidates. To see if you might be eligible for the AIR study, you at least need to comply with the following 5 main study criteria:


When you meet the main study criteria and you are interested to participate in the study, you can contact the outpatient orthopedics clinic of one of the participating hospitals below for an appointment. Please note that for making an appointment you need a referral from your general practitioner.

CAUTION: Trammpolin® has not yet been approved by regulatory authorities for commercial sale and may only be used in a clinical study. Moreover, by contacting the hospital for an appointment you show your interest in participation in the AIR study, but this says nothing about the real possibility to participate. Other factors may exclude you from participation; only the orthopaedic surgeon who performs the examination will determine your final suitability.

The AIR study is registered in a clinical study database at under number NCT03696836.
