Uni-Compartmental.

Bi-compartmental Knee Arthroplasty

What is Uni-Compartmental or Partial Knee Replacement?

 
 

The knee joint is a cluster of three small compartments, namely the Outer (1), Inner (2), and Knee-Cap (3), compartment. Interestingly knee osteoarthritis (OA) has been described as highly segmental, in other words, wear and tear of the knee has a strong tendency to restrict itself to a particular compartment, most commonly the inner one.

Unicompartmental Knee Replacement is a surgical procedure done to replace only the worn-out inner compartment of the knee. Unlike total knee replacement where the entire joint is replaced, in Un-compartmental knee Replacement at least 70% of the knee joint is preserved.

What is Patello-Femoral (Knee-Cap) Replacement?
Sometimes the Knee-Cap compartment alone can wear out which happens generally after trauma or developmental defects. In these cases, only the Knee-Cap compartment is replaced and the rest of the joint is preserved.

What are the Advantages of Partial Knee Replacement?

 

  • 1. Preservation of normal tissue
  • 2. Near-normal kinematics of the knee
  • 3. Better Knee Function
  • 4. Fast recovery after surgery
  • 5. Minimal incisions and Tiny scar
  • 6. Less pain after surgery
  • 7. Low blood loss
  • 8. Cost-effective
