Now Including an Augmented Tibial Stem (ATS)

InterSpace® Knee

InterSpace Knee is designed to temporarily replace an infected implant during a Total Knee Arthroplasty (TKA) and provide the patient with mobility and predictable, consistent local antibiotic release.1-3

To complement our preformed knee spacer, we now offer an augmented tibial stem (ATS), which comes in multiple size and thickness options to best fit patient anatomy without sacrificing the stem length.

Features and Benefits of InterSpace Knee ATS

Sizing Flexibility
  • 7mm and 12mm thickness options based on patient needs
  • Two width options complementing the existing knee spacer to best fit patient anatomy
Unique Design
  • Augmenting tibial thickness does not sacrifice stem length
  • Fins attached to the stem are designed to act as a guide during placement and to reduce the risk of dislocation
  • When connected, corrugated surface and notch from ATS and keyhole from tibial component are engineered for increased fixation
