A tibial component includes a tibial plate having a top side and a bottom side. A shaft projects from the bottom side for insertion into the medullary space of a tibia for anchoring the tibial component to the tibia. The tibial component includes a positioning device for positioning, in particular steplessly positioning, the shaft on the tibial plate in a plurality of different positions. The positioning device is configured in such a way that the shaft is transferable from one of the different positions into another one of the different positions by a movement in parallel to a positioning plane, which extends in parallel or substantially in parallel to the top side. The tibial component can be part of a knee joint endoprosthesis system.

An articulating joint includes a base member, a suspended member and at least one tension member. The base member includes at least two base member peripheral anchors and a base member intermediate anchor located between the base member peripheral anchors. The suspended member includes at least two suspended member peripheral anchors and a suspended member intermediate anchor located between the suspended member peripheral anchors. The at least one tension member couples the base member peripheral anchors to the suspended member peripheral anchors and couples the base member intermediate anchor to the suspended member intermediate anchor so that the base member and the suspended member are configured for constrained relative articulation with the suspended member partially received within the base member.

A patellofemoral implant arrangement for repairing damage in a patellofemoral articulation of a patient is provided. The patellofemoral implant arrangement includes a femoral trochlear implant, including an articulating surface, and a patellar implant, configured to be inserted, for example with press-fit, into a recess in a patella in such a way that the perimeter of an articulating surface of the patellar implant does not extend beyond a surrounding articulating surface of the patella. The articulating surfaces of the femoral trochlear implant and the patellar implant are designed to allow that they at least partly interact with each other when the implants are implanted into the knee joint and the patella lies in the intercondylar groove of the femur. The articulating surface of the patellar implant may be designed to correspond to the curvature of a simulated healthy articulating surface of the undamaged patella at the site of diseased cartilage.

In a total ankle replacement joint, tibial and talar components are coupled by first and second tension members threaded through the tibial component and the talar component to support the tibial component relative to the talar component. The total ankle replacement joint is configured such that the tibial component rocks relative to the talar component on fixed-length web member segments of the first and second tension members and fixed-length loop member segments of the first and second tension members constrain motion of the tibial component relative to the talar component.

A system and method for improving limb function through the use of percutaneous mechanical and neural interfaces. The system generally uses a hollow long bone axial rod that is inserted into the long bone medullary cavity. A transfer rod with a central channel is mounted to the long bone axial rod. An exterior body attachment is connected to the transfer rod and attachment rings attach muscle groups, fascia layers and dermal layers to the transfer rod. Additionally, the system is configured to collect and transmit nerve signaling data to an external processor and additionally configured to transmit data from the external processor to the plurality of nerves.

An implantable orthopaedic knee prosthesis includes a femoral component including an articular surface configured to engage a tibial bearing and a laterally-angled trochlear groove defined in the articular surface. The trochlear groove of the femoral component is configured to receive a patella component in a first location at a first degree of flexion and a second location at a second degree of flexion.

A femoral component (101) for a knee prosthesis, the femoral component (101) comprising: a body portion (103) having: a lateral portion (109) and a medial portion (111) when in an implanted configuration, wherein a parasagittal plane is located at the intersection between the lateral portion (109) and the medial portion (111); and a patella track (105) extending anterior-posteriorly around the body portion (103), wherein the patella track (105) comprises a first patella track portion (105a) that is directed laterally away from the parasagittal plane as it extends towards a posterior end of the patella track (105).

An orthopedic implant with an inferior portion having a tibia contact surface configured to extend over a tibia; a superior portion opposite to the inferior portion having a tendon contact surface configured to change a position of a patellar tendon by lifting or tilting the patellar tendon when the curved surface of the first portion is engaged with the tibia; a fixation mechanism adapted to attach the orthopedic implant to the tibia; and an adjustment mechanism adapted to change a distance between the tendon contact surface and the tibia contact surface. The invention also includes a method for repositioning a patellar tendon of a patient.

Disclosed herein are a surgical system for patella tracking and a method for selecting a properly-sized patellar implant utilizing the same. The surgical system may include first and second trackers and a patellar tracking system. The first tracker may be configured to contact an unresected or a resected patella, and the second tracker may be configured to contact a bone. The patellar tracking system may be configured to track the first and second trackers during patellar flexion and extension to generate patellar range of motion and patellar trial range of motion. A method for selecting a patellar implant may utilize the first and second trackers and the patellar tracking system.

A surgical implant includes a tray extending from a first end to a second end along a first plane, the tray including an upper surface and a lower surface, a first post coupled to and extending from the tray away from the first plane and configured to be inserted into a bone portion, the first post including a first opening extending through the first post, a second post coupled to and extending from the tray away from the first plane and configured to be implanted into the bone portion, the second post including a second opening extending through the second post, and a fastener removably coupled to the first post and the second post, the fastener extending from a first fastener end to a second fastener end through the first opening and the second opening.
