very interesting video. my acl tore(grade3) 2 weeks ago and i was resting my knee for about 10 days after that i tried to back to walking but my knee is unstable. i started my PT 3 days ago. every time i do neuromuscular electrical stimulation in my PT sessions after that i can walk normal with no limp but after 20-30 min my walking getting back to it weak form and knee feels unstable again. i think its somehow realated to AMI when my knee sorounding muscle stimulated with electrical puls they can make my knee stable again. do you think im right? is there any realation?

The most likely scenario is that the electric stim is activating the muscles and helping them to function better, so that they exert a force which stabilizes the knee. Simultaneously, the electric stim probably also makes you feel better, which would also lead to better movement. Then once you're on the move for a bit and the effects of the electric stim have a chance to dissipate, then the muscles may not activate to the same extent and the pain worsens. Essentially, our joints rely on the passive stability provided by the joint capsule, ligaments, and other inert structures. Our muscles exert force via the tendons which gives the joint active stability. When you have an injury like an ACL tear, it significantly affects the passive stability of the joint, so you become far more reliant and sensitive to the active stability that your muscles exert. Does that make sense? Is that kind of what you thought was going on? Thanks for watching!
