Het team

Ontwikkeling van gewricht sparende technieken is zeer belangrijk voor ArthroSave. Ons bedrijf is de voortzetting van jaren academisch onderzoek, waarin we hard hebben gewerkt om de mobiliteit van jonge patiënten met knieartrose te verbeteren.

Jaren ervaring met kniedistractie in wetenschappelijke trials heeft geleid tot een veelbelovende additionele vorm van een gewricht sparende behandeling. In deze academische setting heeft ArthroSave de KneeReviver distractor ontwikkeld om de kniedistractie behandeling verder te verfijnen.

Sinds 2018 houden wij kantoor in Culemborg. Na een succesvolle implementatie van de KneeReviver in geselecteerde Nederlandse ziekenhuizen, exporteren wij de KneeReviver ook naar het Verenigd Koninkrijk, Duitsland België en Zwitserland.
