Abstract
Articular repair implants, implant components, systems, methods, and tools are disclosed. Various embodiments provide improved features for knee joint articular repair systems designed for posterior stabilization, including deep-dish configurations, and box, cam, and/or post features. Additionally, various embodiments include patient-adapted (e.g., patient-specific and/or patient-engineered) features.
Claims10
A tibial implant for treating a knee joint of a patient, the tibial implant comprising:
- a superior surface generally opposite an inferior surface, the superior surface having a first curvature and having an inferior-most point;
- an anterior portion generally opposite a posterior portion;
- and
- a medial portion generally opposite a lateral portion,
- wherein the first curvature is based, at least in part, on patient-specific information regarding the knee joint of the patient, and
- wherein a height difference in the superior direction between the inferior-most point of the superior surface and a superior-most point of the superior surface in the anterior portion is between about 5 mm and about 10 mm.
A tibial implant for treating a knee joint of a patient, the tibial implant comprising:
- a superior surface generally opposite an inferior surface, the superior surface having a first height relative to the inferior surface and having an inferior-most point;
- an anterior portion generally opposite a posterior portion;
- and
- a medial portion generally opposite a lateral portion,
- wherein the first height is based, at least in part, on patient-specific information regarding the knee joint of the patient, and
- wherein a height difference in the superior direction between the inferior-most point of the superior surface and a superior-most point of the superior surface in the anterior portion is between about 5 mm and about 10 mm.
A system for treating a knee joint of a patient, the system comprising:
- a femoral implant having a joint-facing surface that includes a first curvature that is based, at least in part, on patient-specific information regarding the knee joint of the patient;
- and
- a tibial implant, comprising:
- a superior surface generally opposite an inferior surface, the superior surface having a first curvature and having an inferior-most point;
- an anterior portion generally opposite a posterior portion;
- and
- a medial portion generally opposite a lateral portion,
- wherein the first curvature of the superior surface is based, at least in part, on the first curvature of the joint-facing surface of the femoral implant, and
- wherein a height difference in the superior direction between the inferior-most point of the superior surface and a superior-most point of the superior surface in the anterior portion is between about 5 mm and about 10 mm.
