摘要：
The orthopedic implant locking system may include an eccentric tibial stem having an engagement rod selectively threadingly engageable with a tibial baseplate, a lock housing securable in rotatable and substantial vertical constrained relation relative to the tibial stem, and an extension lock selectively threadingly engageable with the lock housing and including an inner passage keyed to selectively slidably engage the engagement rod in flush engagement therewith. The extension lock may extend or contract in response to rotational movement of the lock housing simultaneously while the extension lock remains in substantial non-rotatable relation relative to the tibial stem. Engagement of the extension lock with the tibial baseplate may generally vertically and rotationally selectively lock the tibial baseplate with the tibial stem and, based on the threaded spaced relation of the tibial baseplate relative to the tibial stem, linearly and eccentrically axially misalign the tibial stem relative to the tibial baseplate.
