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.


To see if you might be eligible for the AIR study, you at least need to comply with the following 5 main study criteria:



CAUTION: Trammpolin® has not yet been approved by regulatory authorities for commercial sale and may only be used in a clinical study. 

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