Hi all, 
 
	About a year ago I had surgery on my meniscus. Everything is mostly fine except occasionally my knee locks up. 
 
	I have found that massaging the popliteus muscle unlocks the knee immediately and I can carry on. It's an easy fix to a annoying reoccurance. 
 
	My question is: are there any exercises, stretches etc that will prevent my knee from locking up in the first place? 
 
	I'm grateful for any suggestions, thank you!
