Partial knee implants and methods for installing the same

A method of preparing a condyle of a femur of a patient to receive a femoral condylar implant using a femoral preparation guide having a distal portion and a posterior portion, the posterior portion have a femoral bone-facing surface and an opposing tibial bone-facing surface, the method comprising:

• attaching a shim to the opposing tibial bone-facing surface of the posterior portion of the femoral preparation guide, the shim having a curved surface;
• positioning the femoral preparation guide such that (i) the distal portion of the femoral preparation guide is adjacent to a resected distal region of the condyle of the femur, (ii) the femoral bone-facing surface of the posterior portion of the femoral preparation guide is adjacent to a posterior region of the condyle of the femur, and (iii) the curved surface of the shim is adjacent to a resected tibial plateau of a tibia of the patient;
• and
• inserting at least a portion of a first pin through a first throughbore in the distal portion of the femoral preparation guide to aid in securing the femoral preparation guide to the femur.

A tibial surgical template for use in a surgical procedure on a tibia of a patient, the tibial surgical template comprising:

• a tibial bone-facing surface;
• a protrusion extending from the tibial bone-facing surface and configured to penetrate a resected tibial plateau to aid in temporarily securing the tibial surgical template to the tibia of the patient;
• a femoral bone-facing surface defining a recess having a floor and a sidewall, the recess being configured to receive at least a portion of a trial tibial insert therein;
• and
• an aperture configured to engage with a drill guide such that a drill can be guided through the aperture and form a hole in the tibia.
