An orthopaedic prosthesis including a tibial tray is disclosed. The tibial tray includes a distal pocket and a plurality of inner pockets. Each inner pocket includes a channel sized to receive bone cement. The tibial tray includes distal-facing surfaces that have a surface roughness (Ra) equal to about 5.0 microns.

The invention comprises a system which determines the cure status of bone cement which is then used in making surgical decisions on the cement use and further comprises a system for aiding in securing an implant to a bone using a cured grout or bone cement. The system includes a device which comprises a frequency sensor joined to a circuit to monitor one or more frequency signals, and to an indicator that emits a signal in response to a current emitted to the circuit by the system while monitoring the state of cure. The invention also relates to surgical methods using the system.

Systems and methods for deploying an implant. An introducer device includes an actuator, a shaft, a tensioning element coupled to the actuator, and an anchor coupled to the tensioning element. The implant includes a proximal neck configured to be removably disposed within a distal portion of the shaft. The proximal neck defines a notch sized to receive the anchor such that the distal portion of the shaft covers the anchor and prevents separation of the anchor from the notch with the tensioning element in a tensioned state. The actuator is configured to be actuated to release tension on the tensioning element so as to permit removal of the proximal neck from the distal portion of the shaft and separation of the anchor from the notch to decouple the implant from the introducer device. The anchor and the proximal notch may include complementary sloped surfaces to facilitate the separation.
