The NEURO LOCK MAX system knee joint is a locked joint, which provides motion control. The patient can unlock it via a lock lever or a pulling cable. It is preassembled in a physiological joint angle of 5°. By exchanging the extension stop and filing the lower part of the joint, a locking in different flexion angles can be achieved.
The system joint has a permanent unlock function and can be used as a free moving, monocentric joint with integrated posterior offset. For this purpose, the lock lever is secured with a locating pin. The patient themself can enable or disable this function.
