Large Joints (Hip and Knee) 2017-12-18T10:22:46+00:00

Mechanical Testing for Hip and Knee Medical Devices

Mechanical testing for large joints is multifaceted, with standards to address fatigue properties of load bearing members, disassembly forces between mating components, range of motion between articulating and sliding components, and wear debris generated from relative motion. Contact us today to discuss the requirements for your specific device. Some commonly tested devices are listed below.

  • Hip stems (cemented, press fit, modular)
  • Acetabular shells and liners
  • Taper connections
  • Tibial trays and liners
  • Femoral components
  • Unicondylar components
