Abstract
Instrumentation and methods are provided for knee arthroplasty which permit rotation of a distal femoral component in the sagittal plane. A guide provides for determination of both a femoral component size and rotation angle at which to install the implant in any specific patient.
Claims20
A method of performing knee arthroplasty procedures, comprising the steps of:
- using a femoral component of a selected size on patients with differing sized femurs by performing, on a patient by patient basis,
- determining an angle of rotation in the sagittal plane relative to a datum feature of a specific patient's femur at which to install said femoral component, said angle at which to install said femoral component being variable from patient to patient, and
- installing said femoral component of said selected size on said specific patient's femur with a distal resection made at said angle determined in said determining step.
