bone to twist back while forcing the bottom leg bone forward will help feedback will prevent an injury from overcompensation fig9 illustrates a counterforce safety system to protect a leg ligament of a user in accordance with another embodiment of the invention the leg of a user 300 has two counterforce safety systems 100 including a sensor trigger 124 each with a brace 702 and side brace 704 that are in proximity to a leg ligament in one embodiment a shared sensor trigger 124 responds to the relative position of the ends of the side braces 704 a rotational torque force from each counterforce safety system 100 is activated to limit a critical twist between the upper and lower legs the rotational torque forces will be activated in opposite directions in order to align both the upper and lower legs until a safe alignment is achieved feedback will prevent an injury from overcompensation in one embodiment a twist sensor not shown is used near the sides of the upper and lower legs in another embodiment inertial sensors not shown in the top and bottom legs could be compared to set a sensor trigger 124 fig1 illustrates a counterforce safety system to protect the meniscus of a knee of a user in accordance with one embodiment of the invention the leg of a user 300 has a counterforce safety system 100 adjacent to the upper thigh with a brace 802 and a side brace 804 and including a sensor trigger 124 one embodiment can lift up the upper thigh right at the moment of maximum compression on the knee normally the foot is planted on the ground so limiting the maximum impact is important if the counterforce.
