    Abstract: An endoprosthesis for a knee joint comprising a femur part (6), a tibia part (8), and a middle part (18) which is articulated on the femur part (6) by a pin (14). The middle part (18) is pivotable with respect to the tibia part (8) about a centering pin (20), and a stop is pivoted which is dependent on the flexion angle. A bearing part (54), acting as artificial meniscus, is arranged between the femur part (6) and the middle part (18), and has a first guide element (56) coaxial to the flexion axis and in engagement with the bearing member (58) of the femur part (6). The bearing part (54) is displaceable with respect to the middle part (18) and also comprises a second guide element (60) in engagement with a guide track (62) of the middle part (18); the pin (14) is arranged eccentric to the bearing member (58), and movement of the flexion axis is forced along an evolute curve. The invention avoids localized load peaks while accomplishing the physiological functions of the knee joint during movement and load.

    Abstract: Hip prosthesis. The femur side hip prosthesis includes both a ball and socket bearing and another (secondary) bearing system which facilitates motion of the type which is primarily in the forward and backward swinging of the leg. In certain embodiments of the invention, the secondary bearing system includes needle bearings and thrust bearings. That secondary bearing system lessens the motion of the ball and socket joint required during common activities such as walking. Certain embodiments of the invention include a modular connection between the stem for placement within the femur and the assembly that includes the secondary bearing.

    Abstract translation: 髋关节假体 股骨侧髋关节假体包括球窝轴承和另一(辅助)轴承系统,其有助于主要在腿的向前和向后摆动的类型的运动。 在本发明的某些实施例中,次级轴承系统包括滚针轴承和止推轴承。 次级轴承系统减少了诸如散步等常见活动所需的球窝接头运动。 本发明的某些实施例包括用于放置在股骨内的杆之间的模块连接以及包括次级轴承的组件。
