Abstract
A prosthetic implant system for reconstructing a knee joint comprises a prosthetic implant and sleeve. The prosthetic implant comprises a tibial tray component for reconstructing a tibia of the knee joint, and a stem configured to extend from the tibial tray component to anchor the tibial tray component in the tibia of the knee joint. The sleeve comprises an outer wall configured to engage with bone, and an inner bore configured to receive the stem. The inner bore is shaped to couple to the prosthetic implant at a first location proximate the tibial tray component while surrounding the stem, and uncouple from the prosthetic implant at a second location spaced from the first location while still surrounding the stem. Methods employing the prosthetic implant system can comprise intraoperatively determining to use the sleeve in a coupled or un-coupled configuration based on a depth of a broach into a broached channel.
