Abstract: Apparatuses and systems including an instrument for manipulating components within a knee joint of a patient are disclosed. Such manipulation can include inserting and/or removing such components to or from a bone of the knee joint. The instrument can include a handle, a body, a plunger, a detent and a collar. The handle can have a proximal end and a distal end and a longitudinal extent between the proximal end and the distal end. The body can be coupled to the handle and can extend distal of the distal end. The body can define a receptacle therein having an opening at a distal end portion of the instrument. The plunger can be moveably disposed within the body and can be moveable between a first position and a second position. The detent can be moveable by the plunger, such that with the plunger in the first position at least a portion of the detent can extend into the receptacle and with the plunger in the second position the detent can be recessed from the receptacle.

Abstract: Methods and systems for determining a patient specific soft tissue location within a joint are discussed. For example, a method can include imaging a target location for an orthopedic implant to collect image data regarding a morphology of the patient, the morphology including at least one of bone size and bone feature. The method can additionally include accessing stored soft tissue data and bone data corresponding to the target location of the orthopedic implant, locating a soft tissue of the patient based at least in part upon the soft tissue data and bone data and the image data, and displaying data including the location of the soft tissue of the patient. This data can be used to created patient specific surgical jigs according to one example of the present application.

Abstract: A knee arthroplasty system for use in a patient's knee joint comprises a spacer block instrument including a base portion, a tibial component extending from the base portion and configured for placement against a tibia, and a femoral component configured for placement against a femur. The femoral component is rotatably coupled to the tibial component. The system further includes one or more spacer block shims structured for removable attachment to the tibial component.

Abstract: Tibial prosthesis having one or more fins for use in a total or unicompartmental knee athroplasty procedure are disclosed. The one or more fins can be adapted to fix a tibial prosthesis to the tibia and can engage with corresponding channels formed in the resected tibia. Additionally, intercondylar components and methods for use in a total or unicompartmental knee athroplasty procedure are disclosed. The intercondylar component can be integral with or attached to a baseplate configured for attachment to a partially resected proximal surface of the tibia that retains at least a portion of the intercondylar eminence and the anterior cruciate ligament (ACL) and/or the posterior cruciate ligament (PCL). Inner surfaces of the intercondylar component can be configured to engage with at least a portion of the intercondylar eminence remaining with the partially resected tibia. In an example, the intercondylar component or the one or more fins can be formed of a porous material, such as to facilitate bone growth.

Abstract: An expandable rod is provided that is sized for insertion into a patient's bone. A method for using the expandable rod to prepare the patient's bone to receive an orthopedic implant is also provided. The expandable rod is adjustable between a first, contracted state and a second, expanded state, the expansion member expanding radially outwardly from the contracted state to the expanded state.
