I have had a long history with my knee. I “broke” my knee after having several ligament reconstruction. The fracture formed from the tunnels that were drilled during the repairs. I am currently on my third surgery to fix the TPF (7th total). Each time they go in the hardware fails before the bone heals. Needless to say I have been in a full leg cast for the last month and have another month to go with the new cast. The number one item I have found that helps with the itching and dampness from this heat is the castcooler (http://www.castcooler.com/). I recently ran into the safe scratch (http://www.safescratch.com/). Both of these products work very well and have made my life sucks less while in a cast.
