Abstract
Implants include fixation features which slidingly receive fixation elements. The fixation features may be negative or positive features, such as undercut channels or posts. Examples include unicompartmental tibial trays having a ridge protruding from the bone-facing side, an undercut channel formed within the ridge. Instruments are disclosed for preparing a ridge-receiving feature in bone.
