Femoral heads, mobile inserts, acetabular components, and modular junctions for orthopedic implants, e.g., hip replacement implants, and methods of using femoral heads, mobile inserts, acetabular components, and modular junctions for orthopedic implants are provided. Prosthetic femoral heads, mobile inserts, and acetabular components are provided that can alleviate soft tissue impingement, reduce implant wear, and/or reduce frictional torque. Modular junctions are provided that can minimize the incidence of loosening and micromotion that can occur at modular junctions of orthopedic implants.

Apparatuses for distal fibula replacement and related methods are described herein. The apparatus generally includes an implantable stem component including a proximal portion that is contoured to have an anterior overlap with a portion of a fibula bone of a patient, and a distal portion that defines a first channel configured to receive a peronaeus brevis tendon and a further defines second channel configured to receive a peronaeus longus tendon. Related methods include placing such an apparatus on the portion of the fibula bone of the patient.

The disclosure is directed to a resilient implant for implantation into human or animal joints to act as a cushion allowing for renewed joint motion. The implant endures variable joint forces and cyclic loads while reducing pain and improving function after injury or disease to repair, reconstruct, and regenerate joint integrity. The implant is deployed in a prepared debrided joint space, secured to at least one of the joint bones and expanded in the space, molding to surrounding structures with sufficient stability to avoid extrusion or dislocation. The implant has opposing walls that move in varied directions, and an inner space filled with suitable filler to accommodate motions which mimic or approximate normal joint motion. The implant pads the damaged joint surfaces, restores cushioning immediately and may be employed to restore cartilage to normal by delivering regenerative cells.

A prosthetic hip joint is disclosed. The prosthetic hip joint includes a femoral component, which further includes a femoral head with a femoral head cavity and an acetabular component. The acetabular component includes an acetabular cup and an acetabular cup insert. The acetabular cup insert and the acetabular cup each has a through hole, where the through holes overlap a location of a native femoral head ligament.

The improved endoprosthetic device surface treatment encourages soft tissue attachment thereto. A porous mesh surface treatment creates on an outer surface of the endoprosthetic device a three-dimensional surface structure similar to cancellous bone. Suture attachment features are provided at various locations around the treated surface structure to initially affix a vascularized soft tissue to the treated surface. As the patient heals the soft tissue grows and infiltrates the porous mesh surface to achieve an attachment strength substantially equal to the surrounding tissue.

An augment for supporting an acetabular shell at an acetabulum of a hip bone. In some examples, the augment can include a body having a first surface and a second surface opposite the first surface. The body can extend from a first end portion that is adapted to be fixed to an acetabular shell, to a second end portion. The body can include a first hole and a second hole, each of the first and second holes extending through the body from the first surface to the second surface. The body can be formed of a porous material that promotes boney ingrowth and can further include a trim marker located in between the first hole and the second hole.

Certain embodiments generally provide an improved tibial base member comprising keel portions that allow one or both cruciate ligaments to be preserved. Other embodiments provide improved lateral and/or medial inserts having a mesial lip that helps relieve and or prevent impingement between the femoral component and the tibial eminence. Other embodiments provide improved femoral components having various chamfers to provide additional clearance with respect to the tibial eminence and posterior cruciate ligament without decreasing bone coverage.

A medical device for implantation in a knee joint of a human patient is provided. The medical device comprises: an inner surface and an outer surface. The inner surface comprises: a first point, a second point, a third point, a fourth point, a fifth point, and a sixth point, all points located on different places along a length axis of said inner surface. A first straight line, reaching from the first point to the second point is parallel to a second straight line reaching from the third point to the fourth point, which in turn is parallel to a third straight line reaching from the fifth point to the sixth point. The first and third straight lines are of equal length and the second straight line is longer than the first, furthermore the third straight line is positioned between the first and third straight lines. Wherein the medical device comprises a first articulating surface adapted replaced the surface of the contacting surface of the medial condyle, a second articulating surface adapted to replace the contacting surface of the lateral condyle and a third articulating surface adapted to replace the contacting surface of the patella.
