In one embodiment, the present disclosure relates to an acetabular implant system with a liner and a sleeve. The liner includes a convex outer surface shaped to correspond to an interior of an acetabular cup and has an equatorial region and a polar region. The convex outer surface includes a plurality of liner engagement features thereon. The sleeve includes an inner surface with a plurality of sleeve engagement features thereon. The inner surface of the sleeve is sized to be flush with the convex outer surface of the liner. When the sleeve is engaged with the liner, the liner engagement features engage the sleeve engagement features.

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.

A haptic robotic system for reaming an acetabulum prior to inserting an acetabular cup is more accurate than conventional instruments and may reduce the risk of dislocation and improve durability of a hip implant. Disclosed is a three-dimensional tool path, referred to as a haptic volume. Once the haptic volume is implemented into the software of a haptically constrained surgical robotic system, the cutting tool or reamer can only be utilized within the haptic volume. The haptic volume guides the surgeon in preparing the final reamed bone surface with a greatly reduced chance of the reaming unintended bone and greatly increases the chance that the reaming procedure may be carried out using one reaming tool, or using a single-stage reaming process.

Haptic volumes for reaming during arthroplasty

A method of surgically preparing a patella for implantation of a patella prosthetic component is disclosed.

Patella orthopaedic surgical method

An orthopaedic surgical instrument that includes a patella resection guide is disclosed. The patella resection guide includes a body having a substantially planar upper surface that defines a patella cutting guide surface and a first jaw having a first tooth, and a second jaw positioned opposite the first jaw. The second jaw is movable relative to the first jaw and includes a second tooth extending toward the first tooth that defines an axis along which the second jaw is moveable relative to the first jaw. The patella cutting guide surface defines a resection plane that extends through a patient's patella when the patella is positioned between the first jaw and the second jaw.
