What is Total Knee Arthroplasty (Knee Replacement)?

Indications for Total Joint Reconstruction

End-stage tricompartmental gonarthrosis unresponsive to physical therapy, viscosupplementation, or biological agents constitutes the primary indication. The objective is lasting pain eradication and alignment restoration.

Surgical Principles

• Precision bone cuts removing arthritic joint contours
• Implantation of cobalt-chromium or titanium femoral and tibial components
• Insertion of a cross-linked polyethylene bearing insert for low-friction articulation
• Correction of severe mechanical axis deviations
