* When the patella experiences forces which push it off center and against the sides of the groove it causes pain, inflammation, and roughening of the underside of the patella. This is bad
* Ice is your friend.
* There are many potential causes for PFS. One of my issues is a weak VMO. Specific quad strengthening exercises have been prescribed, so I've been diligent about becoming a gym queen. Ha!
* PFS is an overuse/overload injury. It is strongly recommended to reduce knee activity during treatment. I've been nudging my PT about safe aerobic activity. She recently suggested swimming. Watch this space.
* Some of my exercises require a concerted effort on my part to keep my knee joint properly aligned with my foot to retrain my muscles. Until this becomes second nature, running has a real risk of undoing progress. That would be bad.
* Knee taping is controversial. Studies suggest that it provides short term relief to some PFS patients by helping with patella positioning. I wasn't one of them. No more sharpei knee for me.
* The Euflexxa injections were aimed at fixing some of the roughening damage. PT mentioned today that my knee is noticably less crunchy now. This is good.
There you have it - almost as if I know what I'm talking about.
