Knee unicompartmental or total prosthesis installing device, has tibial telescopic plate for verification of tibial mechanical axis, and jig or virtual condylar implant applied on posterior cut to allow distal cutting of condyle

摘要

The device has a tibial cutting jig, a tibial plate (1, 9), and a semi-circular rod applied on a tibial spine, and a tibial telescopic plate (3, 2) for verification of tibial mechanical axis pointed on a magnetized patch fixed on the center of a femoral head. A jig (4) or virtual condylar implant is applied on a posterior cut to allow distal cutting of the condyle.
