About us


Development of joint preserving surgical procedures is of paramount importance for ArthroSave. Our company is the continuation from years of academic research, in which we worked hard to solve the mobility issues for younger patients with knee osteoarthritis.

Years of experience with knee joint distraction in scientific coordinated trials resulted in a potent additional form of joint preserving treatment. Furthermore, in an academic setting, ArthroSave developed the KneeReviver distractor to further refine knee joint distraction treatment.

Since 2018 we have a business office located in Culemborg. After a successful launch of the KneeReviver in selected hospitals in the Netherlands we also export the KneeReviver to Belgium, United Kingdom, Switzerland and Germany.

The team consists of:
