Systems and methods for joint replacement are provided. The systems and methods include a surgical orientation device and at least one orthopedic fixture. The surgical orientation device and orthopedic fixtures can be used to locate the orientation of an axis in the body, to adjust an orientation of a cutting plane or planes along a bony surface, to distract a joint, or to otherwise assist in an orthopedic procedure or procedures.

An orthopaedic surgical instrument system for use during a surgical procedure to implant an orthopaedic knee prosthesis includes a tibial trial component adapted to be positioned on a surgically-prepared proximal end of a patient's tibia. The tibial trial component has a base plate and a central post extending upwardly from a superior surface of the base plate. A superior surface of the central post has a ramp surface defined therein, with the ramp surface inclining superiorly in the anterior-to-posterior direction.

A three-dimensional (3-D) orthopedic drill guide device for accommodating a bone drill during an orthopedic surgery is disclosed. By establishing two specific angles in relation to the bone fascia, the device acts as a guide for bone drilling locations. In one specific instance, it is an optimal 3-D drill guide for the direction and Gamma angle (resulting from the devices Alpha and Beta angles of the device) of a drill hole in a femoral bone when used to replace an injured anterior cruciate ligament (ACL).

An exemplary trial component is configured to be attached to a resected bone having a resection surface, and includes a body portion and a sliding fastening mechanism movably coupled to the body portion. The body portion has an articular surface, a bone-facing surface, and at least one drill guide extending through the articular surface and the bone-facing surface. The sliding fastening mechanism includes at least one post extending beyond the bone-facing surface, and the post is operable to engage the resection surface to retain the position of the sliding fastening mechanism relative to the bone. When attached to the bone, the trial component is structured to selectively retain the position of the body portion relative to the bone, and to selectively permit adjustment of the position of the body portion relative to the bone.

An instrument for navigating to a target area near a subchondral defect of a bone and associated methods are disclosed. The instrument can include a body portion having a patient specific surface defining a negative impression of a portion of a skin surface of a patient, and a targeting device coupled to the body portion, the targeting device including a rail and at least one device portal configured to guide a device into a subchondral region of the bone for treatment at the target area.

A system and process for performing orthopedic surgery is provided that uses a patient's existing implant as a registration tool in an orthopedic surgical procedure. The systems and processes may be used with computer assisted systems or navigation systems to aid in the removal of bone, bone cement, or a bone prosthesis, typically a bone prosthesis used in hip replacement surgery, knee replacement surgery, and the like. The removal of the prosthesis may be done by conventional methods, with navigation systems, robotic assistance or articulating hand held systems. The removal of bone and/or bone cement may be performed with navigated systems, robotic systems, articulating hand-held systems and combinations thereof.

Systems and methods are described herein for resurfacing bones, and in particular, for detecting and resurfacing one or more femoroacetabular impingements (FAIs). A FAI resurfacing controller may be used to perform this detecting and resurfacing of FAIs. The FAI resurfacing controller may include a bone model generator to receive bone imaging and to generate a model of at least one osteophyte and of a surface of a native bone surrounding the at least one osteophyte. The FAI resurfacing controller may include an osteophyte identifier to set a virtual 3D boundary surface between native bone surface and the at least one osteophyte. The FAI resurfacing controller may include a resurfacing navigator to generate and output a navigation file. The navigation file may include the model with the 3D boundary surface between native bone surface and the at least one osteophyte.

A suture transport system is disclosure for placing a flexible member along a tunnel, the system including a means of transporting a flexible member along a tunnel from a first opening in the tunnel through to a second opening at an opposite end of the tunnel, such that the flexible member extends from both the first and second opening. The system also includes a means of capturing a portion of the flexible member at the second opening, to inhibit the flexible member from retracting into the tunnel second opening. The means of capturing includes an aperture for capturing the portion of the flexible member.

An orthopaedic joint replacement system is shown and described. The system includes a number of prosthetic components configured to be implanted into a patient's knee. The system also includes a number of surgical instruments configured for use in preparing the bones of the patient's knee to receive the implants. A method or technique for using the surgical instruments to prepare the bones is also disclosed.

A surgical measurement instrument for use in surgery is configured so that a measurement operation can be more readily performed using this surgical measurement instrument. The surgical measurement instrument has a laser application portion. The laser application portion is used in surgery to perform treatment on a tibia of a patient. The laser application portion can apply a laser beam to measure a positional relationship between the tibia and a knee joint center.
