Patella clamp

An orthopaedic surgical instrument includes a patella trial and drill guide that may be used to both perform a surgical trial of the patellofemoral joint and guide the surgeon in drilling a number of anchor holes in the patella of the patient.

Patella drill guide and trial surgical instrument

An orthopaedic prosthetic component comprises a fixation peg including a porous three-dimensional structure configured to permit bone in-growth. The porous three-dimensional structure has an outer surface boundary. The fixation peg includes a plate attached to the porous three-dimensional structure at the outer surface boundary. The plate includes a tapered body having an outer wall that faces away from the porous three-dimensional structure and is devoid of any openings.

Hybrid fixation features for three-dimensional porous structures for bone ingrowth and methods for producing

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.

System for use in knee surgery

An orthopedic surgical instrument includes a patella trial and drill guide that may be used to both perform a surgical trial of the patellofemoral joint and guide the surgeon in drilling a number of anchor holes in the patella of the patient.

Orthopaedic surgical instrument assembly for implanting a prosthetic patella component

Method for surgically implanting a prosthetic patella component

A trial kit for a hinged knee implant system is disclosed. The trial kit includes a tibial base plate trial, an adaptor and a tibial bearing insert trial. The adaptor and insert trial can be assembled and the assembly mounted on the tray trial by sliding the assembly in an anterior-posterior direction on the tray trial. The adaptor has a post with a cross-piece. The insert trial has openings and channels to receive the post and cross-piece. The openings are sized, shaped and oriented so that the cross-piece of the elongate post must be oriented in different directions to pass through the different openings.

Trial kit for knee prosthesis system

An orthopaedic implant assembly includes a plurality of commonly-sized dome patella components. Each of the commonly-sized dome patella components may be provided in various thicknesses and/or peak surface diameters.

Knee prosthesis having commonly-sized patella components with varying thicknesses and peak surface diameters

An orthopaedic surgical instrument includes a patella drill guide having a first bracket, a second bracket coupled to the first bracket and moveable relative to the first bracket. The second bracket includes a drill plate having a plurality of guide holes defined therein.

Patella clamp and drill guide surgical instrument and method of use

A patella drill guide includes a base portion rotatably mounted on a bone-gripping component. A trial portion with a contoured articulation surface is above the base portion. The base portion and trial portion have aligned drill guide bores. The base portion and trial portion can be rotated together on the bone-gripping component to optimize the positions of the drill guide bores with respect to the patella surface, thereby optimizing the locations of the mounting pegs of the patella implant component on the patella to optimize the orientation of the patella implant component. The base and the bone-gripping component may be unitary so that the entire assembly rotates on the patella about the central longitudinal axis of the bone-gripping component.

Rotatable patella drill guide

An orthopaedic implant assembly includes a plurality of dome patella components and a plurality of anatomic patella components. Each of the dome patella components and the anatomic patella components is interchangeable with a plurality of femoral components. Each of the plurality of dome patella components and each of the plurality of anatomic patella components are configured to be positioned in contact with any of the plurality of femoral components.

Knee prosthesis having cross-compatible dome and anatomic patella components

A patella drilling system includes a clamp and a patella drill guide. The clamp includes an arm with a pointed tip that is received in a dimple on the surface of the patella drill guide and another arm with a bone-gripping member spaced from the tip. The clamp is used to hold the patella drill guide firmly against the resected posterior surface of the patella while the surgeon drills into the patella to form holes for mounting pegs on the implant. The clamp may allow the patella drill guide to be pivoted while clamped so that the orientations of the guide bores may be optimized. The system includes an optional cap that may be used on the pointed tip of the clamp to hold the implant firmly in place while the bone cement sets.
