• Replaces Damaged Bearing Surfaces
  • Stemless Implant = Minimally Invasive
  • Limited Disruption of Soft Tissues
Interpositional design rationale

The design philosophy behind all Ensemble devices is to minimize bone-on-bone contact using stemless, interpositional implants that match the natural anatomy of the joint and preserve critical stabilizing soft tissues.

Proprietary Ensemble joint replacements achieve stability through the shape of the implant, including the peripheral protrusions that act to keep the implant centered in the joint space.
