What kind of physio will I need?

No Physical Therapy should ever hurt but at first it will be uncomfortable. If you feel pain then tell them to stop. You will probably do some stretching exercises. Hot Packs for 20 minutes, local maging of the knees and occasional they use electricity therapy. They use small amount of current to stimuli the blood circulation and later on you will work with the large rubber bands to do resistance training. On your first visit they will be an evaluaton made and they will tell you what they are going to do for you. Nothing to be scare of.
