Today I was moving a 31" tv (CRT) with a total of 3 people (including me) going downstairs into a basement and I felt one of my knee was about to give... (about to buckle) but it didn't. I just felt pain. thankfully there was no pain afterward and my rom was ok.
Also usually at home when I am or am not weight training, moving my knees to rom will cause pop sounds. What does it mean. If I continue to do full range squat (which is what I am doing) help the issue or should I do some supplement exercise (like what?) to supplement it? I find articles on hip (small muscle such as abductor or adductor) but is there something like that for the knees? Thanks
