    Abstract: Certain versions generally provide an improved tibial base member (for example, but not limited to, 10) comprising keel portions (for example, but not limited to, 14a, 14b, 14c) that allow one or both cruciate ligaments to be preserved. Other versions provide improved lateral and/or medial inserts (for example, but not limited to, 110, 210) having a mesial lip (for example, but not limited to, 118, 128) that helps relieve and/or prevent impingement between the femoral component (for example, but not limited to, 400) and the tibial eminence. Other versions provide improved femoral components (for example, but not limited to, 400) having various chamfers (for example, but not limited to, 404, 410, 470) to provide additional clearance with respect to the tibial eminence and posterior cruciate ligament without decreasing bone coverage.

    Abstract translation: 某些型式通常提供一种包括龙骨部分（例如但不限于，14a，14b，14c）的改进的胫骨基座部件（例如但不限于10），其允许一个或多个 两个十字韧带都要保存。 其他版本提供了具有中唇（例如但不限于118,128）的改进的侧向和/或中间插入物（例如但不限于110,210），其有助于缓解和/或防止 股骨组件（例如但不限于400）和胫骨隆凸。 其他版本提供了具有各种倒角（例如但不限于404,410,470）的改进的股骨部件（例如但不限于400），以相对于胫骨隆凸和后十字韧带提供额外的间隙，而没有 减少骨骼覆盖率。

    Abstract: Systems, devices and methods that improve the placement of orthopedic components and/or instrumentation during surgery. In one particular embodiment, the systems, devices and methods provide drill guides that remove the need for three-handed placement of implant components and reduce complications of implant and fixation member placement. Also disclosed is a sheath with a rounded tip that engages a spherical recess of a patient matched cutting block to reduce the ability of the first fixation pin to communicate unintentional moment/torque to the patient matched instrument through a new articulation between the pin and the guide. Once the first fixation pin has been placed to secure the patient matched instrument to the bone, the effect of subsequent pins is greatly diminished. Subsequent pins may or may not also be decoupled rotationally.
