3DKnee™ System

Active Confidence in Every Step.

The 3DKnee is a premium high flexion total knee replacement designed after a decade of research. The 3DKnee instills confidence through every step of the total knee replacement process, from the surgeon’s joint selection decision, to the surgical procedure and patient post-operative function.

Walt's Ride - Surgical Knee Patient Testimonial

Provides excellent power, especially early in flexion, by rolling out to engage the patella quickly, while maintaining great leverage by preventing anterior slide and shortening of the quadriceps lever-arm. Rollout of the femur aligns the quadriceps to the center of the patella, improving quadriceps leverage while reducing patella stresses.

Tibial Component

  • Asymmetric baseplate
  • Winged keeled geometry
  • Two tibia size options for each 3DKnee insert

Femoral Component

  • Congruent lateral condyle
  • Deepened and lateralized patella groove
  • Wide medial condyle
  • Constant axis curvature for increased contact area up to 80°

Insert

  • Direct Compression Molded or e+™ options
  • Congruent lateral condyle
  • Size specific for optimal congruency to the femur
  • Centered posteriorly to encourage increased femoral rollback
  • Wide medial condyle to reduce contact stresses

Domed Patella

  • Domed Geometry for optimal contact area with the deepened trochlear groove
  • Available in sizes 26-38mm
