A method and instrumentation for performing a patellofemoral arthroplasty orthopaedic procedure includes coupling an anterior cutting block to a femur of a patient such that the cutting block references local anatomy of the femur. The anterior cutting block is used to perform a number of bone cuts to establish a trochlear cavity in the femur. The trochlear cavity is formed such that a trochlear prosthesis may be inset into the cavity and substantially flush with the surrounding cartilage. A finishing burring guide and burr bit may be used to detail the shape and/or size of the trochlear cavity. Additionally, a trochlear drill guide may be used to facilitate establishing peg holes in the patient's femur to receive corresponding pegs of the trochlear prosthesis.

Orthopaedic surgical instrumentation for performing a patellofemoral arthroplasty procedure

An orthopaedic knee prosthesis includes a tibial bearing and a femoral component configured to articulate with the tibial bearing. The femoral component includes a posterior cam configured to contact a spine of the tibial bearing and a condyle surface curved in the sagittal plane. The radius of curvature of the condyle surface decreases gradually between early-flexion and mid-flexion. Additionally, in some embodiments, the radius of curvature of the condyle surface may be increased during mid-flexion.

Orthopaedic knee prosthesis having controlled condylar curvature

A number of orthopaedic surgical instruments are disclosed. A method, apparatus, and system for fabricating such instruments are also disclosed.

Apparatus and method for fabricating a customized patient-specific orthopaedic instrument

An orthopaedic knee prosthesis includes a femoral component having a condyle surface. The condyle surface is defined by one or more radii of curvatures, which are controlled to reduce or delay the onset of anterior translation of the femoral component relative to a tibial bearing.
