The NEURO LOCK MAX system knee joint is a locked joint, which provides motion control. It is pre-assembled in a physiological joint angle of 5°. The patient can unlock the system joint with its lock lever. Furthermore, the NEURO LOCK MAX system knee joint offers various alternative functions:
- Alternative Function 1: With accessory parts, it is possible to achieve a locking in different flexed positions. For this, it is necessary to exchange the extension stops and to adjust the system joint by filing the joint's lower part.
- Alternative Function 2: In addition, it is possible to convert the NEURO LOCK MAX system knee joint from a locked into a free moving, monocentric system joint with integrated posterior offset by removing the locking parts.
Temporarily, the system joint can also be used as a free moving system joint. Then, the lock lever is fixed with a pin. This function, including its reversion, can be switched by the patient any time.
