A femoral sizing instrument for use in a knee joint replacement procedure has a housing which includes formations by which it can be located relative to the femoral posterior condyles. A cortex arm has a tip for engaging the anterior cortex of the femur and a sulcus arm has a tip for engaging the sulcus. Each of the cortex and sulcus arms can be adjusted relative to the housing to adjust the distance between its tip and the posterior condyles measured generally parallel to the anterior posterior axis. The instrument includes at least one scale for indicating the positions of the tips of the cortex and sulcus arms relative to the posterior condyles.

Femoral sizing instrument

A cutting guide instrument for use in a cutting step in an orthopedic surgical procedure comprises a reference component comprising a first element which can be attached or otherwise aligned relative to the bone in a predetermined arrangement and a locator arm. The invention further comprises a cutting block comprising a reference surface which can be engaged by a cutting tool to define the location and orientation of the tool during the cutting step. The cutting block further comprises at least one fixation bore for receiving a fixation pin to fix the cutting block to the bone. The locator arm can be fitted against the reference surface so that the reference component and cutting block are arranged in a predetermined manner.

Orthopaedic cutting guide instrument

Patient specific surgical instruments, and in particular cutting guides, and methods of use and manufacture are described. The surgical instrument can be used in an orthopaedic arthroplasty procedure to be carried out on a joint of a patient and can allowing soft tissue balancing for the joint. The instrument comprises a body having an attachment area configured using data specific to a bone of the joint of the patient so as to attach to the bone in a unique position. The instrument includes at least a first cutting guide and an adjustment mechanism operable to change the position of the cutting guide relative to the bone.

Surgical instrument

A method of trialing prosthetic components of a knee prosthesis including positioning a femoral trial component on a surgically-prepared distal end of a patient's femur, assembling a tibial bearing trial component, and positioning the tibial bearing trial component on a tibial base trial component seated on a surgically-prepared proximal end of a patient's tibia. The method may also include adjusting the patient's leg with the tibial bearing trial component engaging the femoral trial component, and readjusting the patient's leg with the tibial bearing trial component engaging the femoral trial component after positioning the tibial bearing trial component on the tibial base trial component and a keel punch.

Method of trialing a knee prosthesis

An orthopaedic surgical instrument system that includes an orthopaedic surgical instrument adapted to be positioned on a proximal end of a patient's tibia, and a tibial bearing trial assembly configured to be coupled to the orthopaedic surgical instrument. The tibial bearing trial assembly includes a plurality of tibial bearing surface trial components and at least one shim.

Trialing system for a knee prosthesis and method of use

A method of assembling a surgical instrument includes selecting a tibial bearing surface trial component, orienting a shim relative to the tibial bearing surface trial component, and securing the shim to the tibial bearing surface trial component.

Method of using a trialing system for a knee prosthesis

A femoral sizing instrument for use in a knee joint replacement procedure has a housing which includes formations () by which it can be located relative to the femoral posterior condyles. A cortex arm () has a tip () for engaging the anterior cortex of the femur and a sulcus arm () has a tip () for engaging the sulcus. Each of the cortex and sulcus arms can be adjusted relative to the housing to adjust the distance between its tip and the posterior condyles measured generally parallel to the anterior posterior axis. The instrument includes at least one scale () for indicating the positions of the tips of the cortex and sulcus arms relative to the posterior condyles.

An instrument for use in determining an anterior-posterior dimension of a femur during a minimally invasive surgical procedure includes a body having a base and a member extending upwardly from the base, said member providing a first part of a sliding mechanism. A stylus includes a stylus support providing a second part of a sliding mechanism which can engage with the member to allow relative sliding movement between the stylus and base, and a stylus member mounted on the stylus support. An implant size indicator interacts with the sliding mechanism to be moved relative to a scale by the member to indicate a size of an implant corresponding to the relative positions of the body and stylus.
