InterSpace Knee

InterSpace® Knee

THE FIRST PRE-FORMED TEMPORARY KNEE SPACER WITH GENTAMICIN FOR TWO-STAGE REVISION ARTHROPLASTY

InterSpace® Knee is designed to temporarily replace a Total Knee Arthroplasty (TKA) when the implant is removed as a result of infection. InterSpace Knee is a partial load-bearing structure consisting of Gentamicin impregnated PMMA bone cement.

 

InterSpace Knee

Advantages

  • New High Release formulation affords an increased surface area, which allows for greater antimicrobial activity than other treatment options1
  • Maintains joint space and allows limited mobility with partial weight bearing*
  • Improves quality of life between procedures2,3,4
  • Provides predictable, consistent local antibiotic release5
  • Facilitates implant placement during second-stage revision with greater ease for the surgeon2,3,6
  • Reduces hospitalization and allows for a seamless transition to rehabilitation and physical therapy6,7
  • Offers functional success rates equivalent to non-infected revisions.8

*Partial weight bearing must be assessed on an individual basis with relation to the anatomic condition of the local bone, bone quality and clinical conditions of the patient during rehabilitation stages. Care must be taken to minimize the risk of damaging bone tissue and the implant through excessive weight bearing or forced mobilization.
