Knee pop

[phyzioroz]

Hello everybody

I was doing a yoga class and we were doing a back twist - you sit one leg is bent and over the other leg, holding the bent knee and twisting with the chest to the opposite direction. Coming out of this pose, the lady next to me started yelling that she can’t straighten her leg, she was complaining of pain behind her knee. I supported her head trying to calm her down and gently massage her thigh, after a minute there was a pop and everything resolved (except of her emotional distress.)We used an ice pack however there was no immediate swelling (she stayed there for about 1/2 an hour).
What would you think it is? What steps will you take after this incident?

Thanks for your help

hi

i think her meniscus changed the place. she should improve leg function and temporarly avoid knee twisting action.
take care

Hello PhysioRoz,
I agree with Yarok that the most likely reason for the pop will be a stressed meniscus. Sometimes a patello-femoral malalignment can create a click upon release
when the quads are in a tightened or protective contaction position. The only other pops can be synovial fluid vacuum pop or a bakers cyst - unlikely.
The situation should be self resolving unless a meniscal tear has occurred and given resolution of the situation is also unlikely.
Advice: avoid extreme flexion rotation of the knee during this exercise in future.
