Hurt right lcl 2 months ago knee is still stiff and painful some popping but feels stable how long is the healing process?

Difficult to know. An lcl injury is much more complex than typical mcl, acl, or PCL injuries. It is often associated with one or more of the other ligament tears. Because if this, there is a no one way to describe the healing process. This must be individualized at your friendly neighborhood sports medicine specialist! good luck!
LCL SPRAIN. It may take another month to fully heal. Suggest therapy program to alleviate your stiffness. Also MRI to make sure you do not have a meniscus tear which could cause the popping.
