An orthopaedic surgical instrument includes a customized patient-specific 5-in-1 cutting block having a plurality of ribs and cutting guide slots extending between each rib. A bone-facing surface of each rib has a customized patient-specific negative contour configured to receive a portion of a corresponding positive contour of the patient's femur.

Customized patient-specific orthopaedic surgical instrument and method for preparing a patient's femur

An orthopaedic surgical instrument is provided having a first customized patient-specific surgical instrument and a second customized patient-specific surgical instrument configured to be removably coupled to the first customized patient-specific surgical instrument. The second customized patient-specific surgical instrument includes a body positioned in a gap defined between posteriorly-extending arms of the first customized patient-specific surgical instrument.

Customized patient-specific orthopaedic surgical instruments

An orthopaedic surgical instrument includes a customized patient-specific surgical instrument having a body. The body has a bone-facing surface and an outer surface positioned opposite the bone-facing surface. The body includes a number of bone-contacting segments raised relative to the bone-facing surface. The bone-contacting segment include negative contours shaped to match corresponding positive contours of a patient's bone. The positive contours correspond to silhouette curves of a three-dimensional model of the patient's bone that correspond to contours of the patient's bone captured in images used to generate the model. The body further includes a number of surgical guides extending from the outer surface to the bone-contacting surface or the bone-facing surfaces. A method associated with the instrument is also disclosed.

Customized patient-specific orthopedic surgical instruments are disclosed. Methods for fabricating and using such instruments are also disclosed.

Customized patient-specific orthopaedic pin guides

Customized patient-specific orthopaedic surgical instruments are disclosed. Methods for fabricating and using such instruments are also disclosed.

A tibial insert includes a platform defining an upper bearing surface and a bottom surface. A keel of the tibial insert is coupled to the bottom surface of the platform and includes a bore extending along a width of the keel. The bore is formed to receive a fastener therein.

A tibial insert includes a platform defining an upper bearing surface and a bottom surface. A keel of the tibial insert is coupled to the bottom surface of the platform. A surgical method for knee anthroplasty is also disclosed.

Tibial insert and associated surgical method

A tibial insert includes a platform defining an upper bearing surface and plurality of keels of the tibial insert extend downwardly from the platform. A surgical method for knee arthroplasty is also disclosed.

Tibial insert having multiple keels

A knee joint is repaired by implanting a trochlear implant component, a patellar implant component and an anti-abrasion stud. The stud has a bearing surface, a bone-facing surface and a fixation post. The fixation post is implanted in the distal femur so that the bearing surface of the stud stands above the patient's native articular cartilage. The stud and trochlear component are implanted in close enough proximity to limit contact between the patellar component and the native articular cartilage around the trochlear component during flexion and extension of the knee joint.

Method of repairing a knee joint

A tibial insert includes a platform defining an upper bearing surface and a bottom surface. A keel of the tibial insert is coupled to the bottom surface of the platform and a rod of the tibial insert extends through a portion of the keel. A surgical method for knee arthroplasty is also disclosed.

Tibial insert having a reinforced keel

A mobile tibial assembly includes a tibial tray and a tibial insert configured to move relative to the tibial tray. The tibial insert includes a platform having an upper bearing surface defining a dwell point of the upper bearing surface. The dwell point is spaced-apart from a center of the bearing surface.

Mobile bearing insert having offset dwell point

A mobile tibial assembly includes a tibial tray and a tibial insert. The tibial tray includes a track that is defined in an upper surface, and the track has a bottom wall that is flat in the medial-lateral direction and convex in the anterior-posterior direction. The tibial insert includes a bottom bearing surface configured to contact the upper surface of the tibial tray and a stem including a circular neck connected to the bottom bearing surface. The bottom bearing surface has a surface area that is less than the cross-sectional area of the circular neck. The convex upper surface of the tibial tray contacts the concave bottom bearing surface of the tibial insert and the tibial insert is freely rotatable about a central axis defined by the stem as the tibial insert is moved along the track relative to the tibial tray in the generally anterior-posterior direction.
