INDUS HIFLEX KNEE FEATURES :
1. INDUS is a posterior stabilized design which increases flexion by causing femoral rollback.
2. The Posterior Condyle has a smaller radius of curvature and therefore is thicker. This makes deep knee flexion possible.
3. Total slope of tibial prosthesis is 70. Increased tibial slope increases flexion.
4. The posterior edge of the tibial poly is chamfered to avoid impingement that occurs during deep flexion.
5. There is an anterior cut out in the tibial poly to accommodate the patellar tendon during deep knee bending.
6. The tibia is monoblock which avoids the problem of backside wear and resulting osteolysis.
7. The post is rounded off decreasing the rotational constraint. This allows for increased rotation without increasing postwear.
8. The tibial poly has a deep dish design both antero posteriorly and medio laterally. This minimizes wear by decreasing point loading.
9. The can housing has been lowered which increases stability and decreases wear.
10. The notch cut is conservative thereby preserving bone stock. |
