11 weeks post-op. Front of ankle and knee pain!?!

Been walking with a bit of a gimp for 2-3 weeks.  PT twice/week.  Stationary bike 5x per week for 25 minutes.  I’m getting occasional knee, and front ankle pain on the injured leg.  Anyone else getting this?  Wearing a knee brace seems to help a bit.

Moral Support/What to expect

I ruptured my Achilles on November 12, and had surgery on November 15. I was doing wind-sprints on a hardwood floor when it ruptured. Being an active person who skis all winter I’ve had a terrible time adjusting emotionally. Tomorrow I go in for my 6 week follow up and am anticipating being able to lose the crutches and start walking with my boot on. I’ve heard/read people having back issues because the boot sits much higher than a normal shoe. Any thoughts on shoe devices to even this out? Has anyone had this issue?
