Torque ('twisting') mechanisms may include jumping while twisting, when the foot lands and grips the ground surface, while the body continues the twisting motion with the full weight of the person behind it. Also kicking, again twisting the body while the susceptible foot is 'planted' on the ground.
It always seems to surprise people that it is the foot on the ground, and not the foot doing the kicking, which gets damaged.
Again the person hears a POP! and the same wobbly knee is the result.
Now torque also puts strain on the menisci, and it is very common for an ACL injury to have an associated meniscal tear. Torque may also tear the meniscus in the absence of a cruciate tear.
If the ACL is gone as well as the meniscus, it is quite common for the meniscal problem to be missed, as the ACL symptoms completely dominate the picture and the victim is so intent on protecting the knee that the meniscus does not have an opportunity of revealing itself with its own set of symptoms.
Pure meniscal tears may allow the person to continue with their activity, although they will likely be in considerable pain and there is often some bleeding into the joint with consequent swelling.
The one time that a victim will definitely not be able to continue with the activity is when a largish piece of the torn meniscus gets stuck between the two long bones, causing locking of the joint so that is cannot bend or straighten. This may unlock by itself but often needs a doctor to manipulate the knee under anaesthetic.
