TKA Prosthesis- LDK X5 Primary Total Knee Arthroplasty
1.
Semi-open intercondylar box ensures stable prosthesis installation and minimum osteotomy.
2.
The posterior condylar curves with optimized graduated radiuses lead to the safe high-flexion angles up to 150 degrees.
3.
The optimized patellar articular surface, deeper patellar groove and wider Q angle range guarantee that the patella has a better track of motion to effectively prevent patellar dislocation.
4.
The posterior condylar curvature is increased. The tibiofemoral articular surface remains surface contact rather than point contact when flexion is up to 135 degrees.
5.
The section curvature changing with the specification and the center distance of the section arc leads to more steady matching to the femoral condyle and a low wear extent.
