T208.1 is a set of thigh prosthetic modular elements. It has a uniaxial knee joint, which is locked in the position of maximum extension for the safety and stability of the patient. When the user wants to sit down or change the angle in the knee joint, he must unlock this movement with a lock attached to the socket of the prosthesis. Very easy to unlock the lock with minimal force. The set is also equipped with mechanical ejection gait phase support. Due to the possibility of blocking the bend of the knee joint, it is designed mainly for people who have problems with prosthetic gait, moving indoors. It has a lock that blocks the joint when the lower leg is straightened in relation to the upper part of the prosthesis. There is also an option to unlock the lock during alternating gait.
