摘要： A method of evaluating a human joint including bones and ligaments under anatomical tension to connect the bones. The method includes: defining a primary datum oriented and fixed in six degrees of freedom; defining at least one secondary datum having fixed origins relative to one of the bones of the joint and relative to a tracking device affixed to the bone; providing an electronic receiving device; associating continuous position and orientation of the at least one secondary datums with respect to the primary datum; while moving the joint, using the electronic receiving device to collect data from the at least one tracking device, wherein the data includes information describing the position and movement in six degrees of freedom of the at least one secondary datum to produce a digital geometric model of at least a portion of the joint; and storing the digital geometric model for further use.

摘要： A method for imparting tension across a human knee joint which includes a femur bone, a tibia bone, a patella bone, a patellar tendon, and ligaments, wherein the ligaments and patellar tendon are under anatomical tension to connect the femur and tibia together, creating a load-bearing articulating joint. The method includes: providing a tensioning device, including: a baseplate; a top plate; and a linkage interconnecting the baseplate and the top plate and operable to move the tensioning device between retracted and extended positions, wherein the top plate is pivotally connected to the linkage so as to be able to freely pivot about a pivot axis; positioning the tensioning device between the femur and the tibia; applying an actuating force to the linkage to move the tensioning device towards the extended position, so as to impart a controlled separating force driving the femur and tibia apart to extend the ligaments.

摘要： An anchor for tensile member(s) includes: a housing having a hollow interior; a collet in the hollow interior of the housing, the collet having a peripheral wall defining a central bore and an exterior surface. The collet is configured to be swaged around the tensile member(s). The collet includes longitudinal grooves in an outer surface of the peripheral wall, each defining a web configured to collapse inward in response to external compressive force. A sleeve has a peripheral wall defining interior and exterior surfaces and is disposed in the housing axially adjacent to the collet. At least one of the collet and the sleeve is tapered and the sleeve and the collet are arranged such that sleeve movement from a first position to a second position will cause the sleeve to bear against the collet, swaging the collet radially inwards around and against the tensile member(s).
