Abstract
A prosthetic knee for active users has a locking head generally parallel to a vertical axis of the prosthetic knee, a chassis, and a plurality of links connecting the locking head to the chassis. The knee includes a swing control mechanism having a flexion stop connected to the chassis and arranged to control the flexion angle of the knee. The flexion stop extends outwardly from the chassis and obliquely relative to the vertical axis. The knee has an audible feedback mechanism for providing the user with information about the location of the knee. The knee may also have a block lock forming a manually activated mechanism allowing load bearing in a flexed position.
