I am almost 12 weeks post op after ACL + medial meniscus repair. I can do 0 degree extension but not the same as my other knee (-7 degree hyperextension). I can't even achieve that passively (-3). I have not been able to do a single heel pop, what should I do?

I have ankle pain due to not being able to extend my knee properly while walking and exercising.
