My wife has had CRPS in her leg for 8 years now and has learned to balance her lifestyle to match her abilities however she has a bad knee from a unique shape to her knee cap grove can make her knee cap dislocate easily and when her leg spasms it pulls the knee cap over to the side, but a knee brace has always for the most part kept it in place until a month ago. it dislocated once badly and now it has dislocated up to 13 times a day with only one day with out a dislocation. Every brace we have tried hasn't held in the patella back from dislocating and last night the hospital put her leg in a full leg cast toes to hip, at full extension, something i didn't know her leg could do without a lot of pt. it keeps the leg from dislocating but the burning is so bad, does anyone know of any tricks to help with cast?

Thanks Jon
