Abstract
A method of surgically preparing a patella for implantation of a patella prosthetic component is disclosed.
Claims18
A method of surgically preparing a patella for implantation of a patella prosthetic component, comprising:
- positioning the patella between a pair of jaws of a patella resection guide,
- rotating the patella about a first axis extending in an inferior-superior direction to adjust the medial-lateral tilt of the patella,
- engaging the pair of jaws with the patella such that rotation about the first axis is prevented,
- rotating the patella about a second axis extending in a medial-lateral direction to adjust the inferior-superior tilt of the patella while the pair of jaws engage the patella,
- clamping the pair of jaws to the patella after rotating the patella about the second axis such that rotation about the first axis and the second axis is prevented, and
- engaging the patella with a cutting saw blade after clamping the pair of jaws.
A method of surgically preparing a patella for implantation of a patella prosthetic component, comprising:
- attaching a patella resection guide to a handle,
- operating a lever of the handle to engage a pair of jaws of the patella resection guide with a patient's patella,
- engaging the patella with a cutting saw blade to resect the patella and create a resected patella,
- detaching the patella resection guide from the handle,
- attaching a patella drill guide to the handle,
- operating the lever of the handle to clamp the resected patella between a pair of brackets of the patella drill guide by (i) contacting the anterior side of the resected patella with a first bracket, and (ii) advancing a second bracket into contact with the posterior side of the resected patella,
- drilling at least one mounting hole in the resected patella by advancing a surgical drill through one of a plurality of guide holes defined in the second bracket,
- operating the lever to withdraw the second bracket from the posterior side of the resected patella after drilling at least one mounting hole,
- attaching the patella prosthetic component on the posterior side of the resected patella, and
- operating the lever to clamp the patella prosthetic component and the resected patella between the pair of brackets.
A method of surgically preparing a patella for implantation of a patella prosthetic component, comprising:
- positioning a resected patella between a first bracket and a second bracket of a patella drill guide,
- engaging the first bracket and the second bracket with the resected patella,
- advancing a surgical drill through one of a plurality of guide holes defined in the second bracket,
- drilling at least one mounting hole in the resected patella,
- disengaging the second bracket from the resected patella,
- attaching the patella prosthetic component to the resected patella,
- rotating a gasket coupled to the second bracket into position between the second bracket and the patella prosthetic component, and
- clamping the gasket, the patella prosthetic component, and the resected patella between the first bracket and the second bracket.
A method of surgically preparing a patella for implantation of a patella prosthetic component, comprising:
- positioning the patella between a pair of jaws of a patella resection guide including a first jaw and a second jaw that is moveable relative to the first jaw,
- adjusting the medial-lateral tilt of the patella by rotating the patella about a first axis extending in an inferior-superior direction,
- engaging a first tooth of the first jaw with a lateral side of the patella and engaging a second tooth of the second jaw with the medial side of the patella to prevent rotation of the patella about the first axis,
- adjusting the inferior-superior tilt of the patella by rotating the patella on the first tooth and the second tooth,
- clamping the pair of jaws to the patella such that movement of the patella is prevented, and
- engaging the patella with a cutting saw blade after clamping the pair of jaws.
