After having pain in my knees after exercise for about 3 years now and putting it down to age I went to see somebody just after Christmas. There followed just under 3 months of physio twice a week which helped the knee that had the least pain but played absolute havoc with the other.
I tried all sorts of things to align the knee caps and even resorted to my "monkey feet"
which use barefoot technology to help you strengthen your feet, ankles, legs and hips etc - http://sites.google.com/site/primallifestyle/fivefingers/Barefoot but the problems with the right knee just wouldn't go away so the Consultant booked me in for an arthroscopy so he could take a look around and tidy up any messy cartilage, as well as treat the under-side of the knee cap that had some pretty extensive Chondromalacia patellae. He showed me the pictures of normal cartilage (white and smooth as ivory) and mine, which was grey and rough like the rocks of volcanic larvae you sometimes find on the beach.
The result is bandage from just under my knee to just under my bum that has to remain on for 5 days! A normal arthroscopy would mean I could remove the bandage after a few days apparently but because of the extensive work mine has to stay on longer to help keep the swelling down.
The pain yesterday was unbearable and I needed crutches to get about, but today I am able to shuffle around the house without and have managed the stairs in both directions. However the bandage has suddenly gone very tight so I think I may have over done and it has swelled up a bit - it's hard to tell when covered by so much padding!
Anyway, now off to attempt the torture, sorry, rehabilitation exercises that I need to do ...
