Methods and apparatus for planning and/or carrying out a total knee replacement surgical procedure on a knee of a leg of a patient are described. Anatomical data for the leg of the patient is obtained, which allows the femoral mechanical axis, the tibial mechanical axis and the joint line of the knee to be determined. A planned proximal tibial cut angle and a planned distal femoral cut angle are determined. A total knee replacement procedure is carried out on the knee of the patient, wherein a distal femoral cut is made using the planned distal femoral cut angle and a proximal tibial cut is made using the planned proximal tibial cut angle.

Methods and system for characterizing ligament properties using elastography are disclosed. An ultrasound system capable of performing shear wave elasticity imaging and/or supersonic shear imaging may retrieve one or more images from a proposed surgical site. The one or more images may be provided to a surgical planning system that identifies one or more properties of ligaments proximate to the surgical site. Musculoskeletal simulations may be performed using the identified properties to preoperatively identify a surgical plan. Preoperative identification of a surgical plan may enable a surgeon to select from more fine-tuning options for a joint replacement than conventional systems.

Disclosed is a bone cutting and shortening system and the method of using the same, the system comprising a bone plate and a cutting guide adapted to slidingly engage by inserting the cutting guide into the bone plate from the overhead direction, the cutting guide adapted to facilitate parallel cutting planes on a bone at precisely ascertainable offset distances, and the bone plate adapted to stabilize the shortened bone after cutting.

A gap gauge is disclosed for facilitating an arthroplasty procedure on a first bone and a second bone of a patient. The gap gauge may include a first plate positionable in contact with the first bone, a second plate positionable in contact with the second bone. The second plate may be displaced from the first plate by a displacement. The gap gauge may further include a balance indicator configured to indicate a balance status between the first plate and the second plate and a pin guide. The pin guide is configured to couple to one of the first plate and second plate and includes a pin hole that is configured to guide a pin for insertion into the second bone. The pin can be used to couple a cutting guide to the second bone to resect the second bone to adjust the balance status.

A surgical guide includes a body defining a first access port and a second access port. The first access port extends on a first longitudinal access parallel with a first edge of the body and the second access port extends on a second longitudinal access positioned non-parallel with respect to each edge of the body. At least one coupling arm extends from the body. The at least one coupling arm defines at least one fixation aperture sized and configured to receive a fixation element through.

An intramedullary tibia alignment system includes an alignment rod, a tibial resection guide and a tibial alignment jig. The tibial alignment jig has a sliding rail, a casing slidably receiving the sliding rail and being attached to the alignment rod, and a user adjustment element rotatably held by the alignment rod. The user adjustment element is functionally connected to the casing by a link element such that a rotation is converted into a pivoting movement. The user adjustment element and the alignment rod are adapted to interlock with each other at a plurality of rotational positions of the user adjustment element. The plurality of rotational positions correspond to different orientations of the alignment rod in accordance with the pivoting movement of the alignment rod.

A surgical kit and a method for performing osteotomy is disclosed. The surgical kit comprises at least two lateral plates and a central plate. The two lateral plates are scaled and fixed over a surgical bone adjacent to each other with an exact distance measured by the scaled lateral plates while the central plate is over two lateral plates to maintain the alignment. The distance is equal to the shortening amount of bone based on the pre-operative measurements. The central plate slides laterally over the two lateral plates to expose the surgical site of the bone. Shortening osteotomy is performed to shorten the bone equal to the distance between the two lateral plates. The central plate then laterally slides over the two lateral plates to achieve the anatomic alignment. Further, the central plate and the two lateral plates are securely fixed to the bone using one or more fasteners.

A system includes a first spacer sized and configured to be received within a resected bone space of a first bone and a second spacer sized and configured to be coupled to a second bone. The first spacer and the second spacer each include a body extending between a bone contacting surface and a coupling surface. At least one shim is positioned between the first and second spacers. The shim includes a body extending between a first coupling surface and a second coupling surface. The first spacer, the second spacer, and the at least one shim position the first and second bones in a predetermined alignment. An adjustable guide including a guide adapter and a guide body is configured to couple to the first spacer and is adjustable on a first axis.

Systems and methods here include a meniscal allograft with a bone block and a technique for making a desired shape in the bone block to be used to implant in a patient. A clamp and/or jig arrangement are disclosed that are able to secure the tissue and allow three corresponding cuts to the tissue using the clamp as a guide to a saw to obtain the desired shape.
