I have been having ankle range of motion issues for several years. I noticed it after my knee pain from an acl surgery, went away. I have gone from a negative range of motion in both ankles to reaching about 12 degrees of rom in left to about 12 in right but…the right does not maintain this number. The right ankle seems to go from 3 to 12 only on physical therapy days. Would love to hear from others. It has been suggested that this has happened due to the fact that I was a toe walker in my youth. I though wonder if I would be having these issues if I had not torn my acl.
