    Abstract: Implants, and processes for installing them, which replace the medial condyle and portions of the patellofemoral channel but preferably not portions of the lateral condyle that articulate relative to the tibia. Processes are provided which allow proper location and orientation of an anterior resection and a distal resection on the femur, which make use of a transition point which can be designated on the bone, for navigating proper positioning of such implants. Proper positioning of the implant relative to the femur for insuring a smooth transition between lateral portions of the implant and the lateral condyle is thus reduced to determining proper medial/lateral location of the implant on the anterior and distal resections. Such implants and processes can allow, among other things, for controlled location and orientation of an implant on the bone which saves lateral compartment bone, which eliminates the need to sacrifice the anterior and posterior cruciate ligaments, and which is adapted for minimally invasive surgery with its attendant benefits.

    Abstract: The embodiments provide provides devices, instruments, and associated methods for treating joint pain. A joint is evaluated using magnetic resonance imaging to detect any defects in the subchondral bone. For example, using T2-weighted MRI images, bone marrow lesions or edemas can be identified, and using T1-weighted MRI images, associated regions of sclerotic bone adjacent to the bone marrow lesion can be identified. The treatment method may involve introducing a bone void filler material at the site to address the bone marrow lesion or edema, and/or drilling and inserting an implant to address the sclerotic bone, bone marrow lesion or edema, and insufficiency or stress fractures. An access path is mapped to a location in the subchondral region where the insufficiency fracture resides. The access path attempts to preserve an articular surface of the joint. A reinforcing member that stabilizes the insufficiency fracture is then implanted via the access path.

    Abstract: A tibia component of a knee arthroplasty to be connected to a tibia includes a first tibia connecting structure and a second tibia connecting structure. The first tibia connecting structure can be inserted into a radial groove on the tibia along a radial direction of the tibia to limit the motion of the tibia component in the axial direction of the tibia. The second tibia connecting structure can be inserted into an axial groove on the tibia along the axial direction of the tibia to limit the motion of the tibia component in the radial direction of the tibia. The first and the second connecting structures provide the radial and axial bonding force to the tibia and the knee arthroplasty, so that the amount of bone cement used can be reduced and may beneficial to revision knee arthroplasty operation.
