Abstract: A method includes receiving by a controller, a surgeon-specific surgery profile for an implantation of an implant into a joint, implant profiles, a patient-specific post-surgery desired functional profile of the joint after the implantation, and bone registration data for a first bone member and a second bone member of a patient are inputted into a surgical plan model to generate a surgical plan. The surgical plan model is designed to achieve the patient-specific post-surgery desired functional profile based at least in part on a plurality of dependencies between a plurality of surgical parameters, the implant profiles, at least one functional parameter representative of the expected functional performance of the joint, and movement-related data of the joint. The surgical plan is outputted on a graphical user interface (GUI) on a surgery assistant device to facilitate the implantation.

Abstract: Eine medial stabilisierende Knieendoprothese (100) für eine Gesamtknie-Arthroplastie unter Erhalt oder unter Dissektion des hinteren Kreuzbandes hat: eine Femur-Lagerfläche (55), welche an einem zur Festlegung an einem distalen Ende eines Femurs eingerichteten Femur-Teil (50) zur Ausrichtung nach distal vorgesehen ist; und eine Tibia-Lagerfläche (15), welche an einem zur Festlegung an einem proximalen Ende einer Tibia eingerichteten Tibia-Teil (10) zur Ausrichtung nach proximal vorgesehen ist. Die Femur-Lagerfläche (55) weist dabei eine konvexe mediale Femur-Kondylen-Lagerfläche und eine konvexe laterale Femur-Kondylen-Lagerfläche auf. Die Tibia-Lagerfläche (15) weist dabei eine konkave mediale Lagerschale und eine konkave laterale Lagerschale auf und ist zur Aufnahme und verschiebbaren Gleitlagerung der Femur-Lagerfläche (55) ohne einen festen medialen Drehpunkt der Femur-Lagerfläche (55) in der medialen Lagerschale (21) eingerichtet. Dabei bilden die mediale Lagerschale und die laterale Lagerschale zueinander eine asymmetrische Tibia-Lagerfläche (15) aus; und bilden die mediale Femur-Kondylen-Lagerfläche und die laterale Femur-Kondylen-Lagerfläche zueinander eine nicht-asymmetrische oder quasisymmetrische Femur-Lagerfläche (55) aus. Dabei stimmen die mediale Femur- Kondylen-Lagerfläche (51) und die laterale Femur-Kondylen-Lagerfläche (52) zumindest in einem anterioren Femur-Kondylen-Radius (R3) jeweiliger anteriorer Flächenabschnitte überein. Dabei bildet die asymmetrische Tibia-Lagerfläche (15) eine außen umlaufende proximale Höhenkontur aus; weist die Höhenkontur einen anterioren Höhenkonturabschnitt mit zumindest einem anterioren Höhenpunkt (H-ant) und einen posterioren Höhenkonturabschnitt mit zumindest einem posterioren Höhenpunkt (H-post) auf, wobei der anteriore Höhenpunkt (H-ant) gegenüber dem posterioren Höhenpunkt (H-post) hinsichtlich zumindest einer Sagittalebene proximal erhöht ist; und bildet ein antero-medialer Höhenkonturabschnitt des anterioren Höhenkonturabschnitts an der medialen Lagerschale (21) einen proximal am meisten erhöhten anterioren Höhenpunkt (H-ant) als einen antero-medialen Gipfelpunkt (P) aus. Ferner wird ein zugehöriges Inlay vorgesch lagen.

Abstract: An anchored implant (204) device including a baseplate (210) and a separate anchor (324). The baseplate and the anchor are individual components that are configured to be separately installed in or on the bone of the patient to provide fixation of the baseplate to a portion of the bone, such as a (resected) tibia. The anchored implant device may be configured with an adjustment feature to allow the baseplate to move in a superior-inferior direction to maintain a flush mounting of the baseplate on a prepared bone surface in an abnormal condition, such as an anchor being at an inadequate depth within the bone. In some embodiments, a contoured implant device (604) may include a device with contoured features configured to engage corresponding features of a prepared portion of a prepared knee joint.

Abstract: Um eine Tibiakomponente für eine Kniegelenkendoprothese, wobei die Tibiakomponente eine Tibiaplatte mit einer Oberseite und einer Unterseite und einen von der Unterseite abstehenden Verankerungsvorsprung zum Einführen in den Markraum einer Tibia zum Verankern der Tibiakomponente an der Tibia umfasst, bereitzustellen, die eine verbesserte Ausrichtung an der Tibia ermöglicht, wird vorgeschlagen, dass der Verankerungsvorsprung an der Tibiaplatte verschwenkbar und/oder um eine Längsachse des Verankerungsvorsprungs verdrehbar gelagert ist. Ferner wird ein verbessertes Kniegelenkendoprothesensystem vorgeschlagen.

Abstract: An intelligent implant includes a component of an implantable prosthesis and an implantable reporting processor (IRP) associated with the implantable prosthesis. The IRP includes a housing having a casing and a cover coupled to the casing, an electronics assembly within the housing, and an antenna within the housing and coupled to the electronics assembly. The antenna is tuned to, and the electronics assembly is configured to enable communication through the antenna at both 2.45GHz and 403MHz (MICS channel). The antenna comprises a flat ribbon configured in a loop and having major surfaces. The antenna is encapsulated within the cover of the housing and is oriented therein with major surfaces of the antenna generally parallel with an inner surface of the cover.

Abstract: 본 발명은 적층공정을 이용한 이탈공차 보완방법에 관한 것으로, 더욱 상세하게는 임플란트 금형에 용융금속을 주입하여 임플란트를 주조하는 주조단계, 주조된 임플란트와 설계 데이터를 비교하여 오차를 측정하는 오차측정단계 및 상기 오차측정단계에서 측정된 오차를 기반으로 임플란트의 치수를 공차 범위 내로 보완하는 오차보완단계를 포함하되, 상기 오차보완단계는 상기 주조단계에서 주조된 임플란트의 표면에 금속을 적층하여 오차를 보완함으로써 수정 불가능한 주조품의 복원을 진행하여 주조과정에서 발생하는 불량률을 낮추고, 임플란트의 형상을 설계된 형상과 최대한 가깝게 구현함으로써 인공관절의 수술 성공률을 향상시키면서도 적층과정에서 별도의 검사시간을 생략함으로써 빠른 보완적층이 가능한 적층공정을 이용한 이탈공차 보완방법에 관한 것이다.

Abstract: A knee joint prosthesis may be for implantation in a knee of a patient. The knee prosthesis may comprise a tibial component configured to be implanted on the tibia and a femoral component configured to be implanted on the femur. The femoral component may comprise a medial condyle with a medial articulation surface and a lateral condyle with a lateral articulation surface. The medial articulation surface and the lateral articulation surface may be shaped substantially symmetrically to each other across a femoral component plane bisecting the femoral component. The tibial component may comprise an articulation surface with a medial articulation side configured to articulate with the medial articulation surface and a lateral articulation side configured to articulate with the lateral articulation surface. The medial articulation side and the lateral articulation side may be shaped substantially asymmetrically to each other across a tibial component plane bisecting the tibial component.

Abstract: The present invention relates to an implant (1, 30, 50, 70) comprising a non-metallic structural part (4, 38, 73) made of a fibre reinforced composite and having isoelastic properties with bone. The implant also comprises a first reference stress level sensor (6, 31, 51, 76) arranged in connection with the structural part, and a second osseointegration level sensor (7, 32, 52, 77) arranged on a surface of the structural part and capable of becoming attached to the bone during osseointegration of the implant.
