Abstract: A line lock system may include a line routed through a plate. The plate may have an elongated body with a plurality of passageways. The line is routed to form at least one one-way slide so no knots are required. The system may include filaments routed through the passageways of the plate or around a dogbone feature of the plate. The filaments may be used to toggle the plate after passage through a hole to prevent withdrawal of the plate back through the hole. The system may include a line lock stabilizer or counter-tension tool to stabilize the line lock as the line is adjusted. The system may include a compression limiter to selectively reduce compression in the one-way slide to facilitate adjustment of the line. The line lock stabilizer, counter-tension tool, or compression limiter may be a filament.

Abstract: A knee prosthesis including femoral and tibial implants, a tibial insert and a cam post assembly. The femoral implant is secured to a femur and has a cam feature and condyles. The tibial implant is secured to a tibia. The tibial insert has articulating surfaces that match the contours of the condyles of the femoral implant, and may have a medial boss that aligns with the tibial implant to provide rotation about a medially displaced rotation axis. A cam post is secured to the tibial implant and passes through a channel of the tibial insert. A motion limiting structure provides limits to motion between the tibial insert and the tibial baseplate. The cam post assembly interacts with the femoral implant cam feature and allows more anatomically correct rollback and femoral external rotation during knee flexion, and varus/valgus support to the femur.

Abstract translation: 包括股骨和胫骨植入物的膝关节假体，胫骨插入物和凸轮柱组件。 股骨植入物被固定到股骨上并具有凸轮特征和髁。 胫骨植入物被固定到胫骨上。 胫骨插入物具有与股骨植入物的髁的轮廓匹配的关节表面，并且可具有与胫骨植入物对准的中间凸起以提供围绕中间移位的旋转轴线的旋转。 凸轮柱固定到胫骨植入物并穿过胫骨插入物的通道。 运动限制结构为胫骨插入件和胫骨基板之间的运动提供了限制。 凸轮柱组件与股骨植入凸轮特征相互作用，并且允许在膝关节屈曲期间更多的解剖学正确的回滚和股骨外旋，以及对股骨的内翻/外翻支撑。

Abstract: Knee prosthesis instrumentation including an insertion tool and a removal tool. The insertion tool may include an offset to provide clearance from a femoral component of the knee prosthesis. The removal tool may be wedge shaped to at least partially encircle a post of the knee prosthesis for removal. A mallet may be used with the instruments to provide additional force for prosthesis insertion or removal. A slide hammer may be incorporated into the instruments themselves.
