Bone cutting system for the leg and method therefor

摘要

A knee bone cut system and method is disclosed. The knee bone cut system supports cutting an anterior portion of a distal end of a femur. The system comprises a sensored insert, a femoral rotation guide, and a remote system to receive and display sensor data. The sensored insert provide data related to load magnitude, position of load, and leg position. The femoral rotation guide has moveable condyles to adjust condyle position in a rapid manner. A pinch mechanism and lock mechanism respectively move the condyles into contact with the sensored insert. Moreover, the femoral rotation guide can be loaded similar to a final installed insert over a range of motion. For example, the patella can be placed on the femoral rotation guide allowing the patella to load the sensored insert. The femoral insert guide includes guide holes that are used in conjunction with a bone cutting jig.

1. A knee bone cut system comprising:
a sensored insert configured to measure load and position of load; a femoral rotation guide configured to couple to a distal end of a femur wherein the femoral rotation guide is configured to couple to a knee ioint with a patella reduced over a range of motion, wherein the femoral rotation guide includes adjustable condyles configured to couple to articular surfaces of the sensored insert, wherein the femoral rotation guide includes drill guide holes configured to support cutting block installation to the femur, and wherein a position of at least one drill guide hole is configured to change as the adjustable condyles are adjusted;and
a remote system configured to receive data from the sensored insert where the remote system is configured monitor load and position of load on the articular surfaces of the sensored insert over the range of motion.
