A method and system for measuring tension, pressure, and distance of knee tissue, the system comprising a prosthetic inlay device comprising at least two platform structures, wherein each of the platforms are supported on a scissor arm structure and a coil spring, a force sensing sensor configured beneath each coil spring, and a connector cable coupled to the force sensing sensors.

An orthopedic distraction device is provides. The orthopedic distraction device includes a first upper paddle for engaging a first bone of a joint, a lower paddle for engaging a second bone of the joint and a displacement mechanism. The displacement mechanism includes a drive assembly operable to move the upper paddle relative to the lower paddle. The lower paddle is releasably connected to the displacement mechanism.

An orthopedic system to monitor a parameter related to the muscular-skeletal system is disclosed. The orthopedic system includes electronic circuitry, at least one sensor, and a computer to receive measurement data in real-time. The orthopedic system comprises a first plurality of shims of a first type, a second plurality of a second type, a measurement module, and the computer. The measurement module houses the electronic circuitry and at least one sensor. The measurement module is adapted to be used with the first plurality of shims and the second plurality of shims. The measurement module has a medial surface that differs from a lateral surface by shape, size, or contour.

The present invention relates to devices and methods for balancing joints, including knee joints. The devices convert unequal forces at a joint to a rotation or displacement of a pointer or gauge. The devices are able to display the relative difference in force between the lateral and medial sides of a joint from flexion to extension. In certain aspects, the devices are useful for balancing the knee during total knee surgery. The devices can be inserted between the trial femoral and tibial components of the knee and measures whether one condyle experiences more force than the other.

A joint distraction device includes a lever body, a foot extending from a bottom surface of the lever body, wherein the foot is coupled to the lever body via a hinge such that the lever body is rotatable relative to the foot, a first plate and a second plate extending from a distal portion of the lever body, wherein the first plate and the second plate are separated by a gap and wherein each of the first plate and the second plate comprise a stopper extending upwards from a top surface of the first plate and the second plate, and a force measurement device coupled to the bottom surface of the lever body and configured to measure a distraction force applied by the lever body at the foot during a joint distraction procedure in which a torque is applied at a proximal portion of the lever body.

The present disclosure relates to a system and method of knee ligament balancing for knee replacement procedures. The disclosure provides a system of components to implant to achieve ligament balancing. In addition, instruments and methods are provided to achieve the desired balance of the ligaments before final fixation.

Surgical instruments, systems, and methods of performing orthopaedic surgical procedures on a patient's knee are disclosed.

Methods of operating a surgical instrument and performing a surgical procedure are disclosed.

A method and apparatus for distracting a joint during a procedure are disclosed. The apparatus can include bone engaging portions and an articulating bearing. The bone engaging portions can engage the bone and then the articulating portions can allow joint motion. The method can use the apparatus to perform a procedure with the apparatus.

A knee gap tensioning apparatus includes: a gap tensioner including: a baseplate; a top plate; a linkage interconnecting the baseplate and the top plate and operable to move the gap tensioner between retracted and extended positions; and wherein the top plate is pivotally connected to the linkage so as to be able to freely pivot about a pivot axis.
