Ankle implants

Ankle implants have gained popularity in orthopedics, especially for patients with advanced arthritis or severe fractures. However, the ankle’s unique range of motion and load-bearing requirements pose challenges in implant design and testing.

Key tests include load and stress testing, wear and fatigue and testing for range of motion and pressure distribution and contact areas. We offer all relevant tests specified in ASTM F2665 plus additional self-developed accredited test methods.
