This disclosure relates to a method of using an adjustable tibial sizer for use in knee arthroplasty. The sizer includes a two-part body comprising: a first body portion, a second body portion, and a connection element extending therebetween.

Method of using an adjustable tibial sizer

Spacer block

Methods and apparatus for planning and/or carrying out a total knee replacement surgical procedure on a knee of a leg of a patient are described. Anatomical data for the leg of the patient is obtained, which allows the femoral mechanical axis, the tibial mechanical axis, and the joint line of the knee to be determined. A planned proximal tibial cut angle and a planned distal femoral cut angle are determined. A total knee replacement procedure is carried out on the knee of the patient such that a distal femoral cut is made using the planned distal femoral cut angle and a proximal tibial cut is made using the planned proximal tibial cut angle.

Surgical planning and method

An orthopaedic joint replacement system is shown and described. The system includes a number of prosthetic components configured to be implanted into a patient's knee. The system also includes a number of surgical instruments configured for use in preparing the bones of the patient's knee to receive the implants. A method or technique for using the surgical instruments to prepare the bones is also disclosed.

This disclosure relates to an adjustable tibial sizer for use in knee arthroplasty, the sizer includes a two-part body comprising: a first body portion, a second body portion, and a connection element extending therebetween. Each of the first and second body portions includes a ramp surface configured for simultaneous movement of the first body portion relative to the second body portion in an anterior-posterior direction and a medial-lateral direction, and method of use thereof.

A total knee replacement procedure is carried out on the knee of the patient, wherein a distal femoral cut is made using the planned distal femoral cut angle and a proximal tibial cut is made using the planned proximal tibial cut angle.

A femoral component () of a knee joint prosthesis has a bearing surface () for articulation with a tibial bearing surface and an opposite bone facing surface (). The bone facing surface has anterior (), posterior (), distal (), anterior chamfer () and posterior chamfer () portions. Medial () and lateral rails () are provided on the distal portion or on at least one of the anterior chamfer portion and posterior chamfer portions of the bone facing surface so that there is at least one recess () between the rails.
