Abstract
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. A method of using such an orthopaedic surgical instrument is also disclosed.
Claims10
A method of performing an orthopaedic surgical procedure on a patella of a patient, comprising:
- forming a hole in the apex of the patella of the patient without the use of a cutting guide,
- resecting the patella of the patient to produce a generally planar resected patellar surface after the hole is formed in the apex of the patella of the patient, and
- positioning a drill guide, having an alignment bore formed therein, on the resected patellar surface such that the alignment bore of the drill guide is aligned with a portion of the hole formed in the patella of the patient.
