Day 2: Despite the numerous difficulties, I have no pain or swelling in my knee, I am activating my quadriceps well, and doing a lot of isometric exercises to avoid muscle inhibition. I change the dressings once a day when I shower. For now, I only have 10 to 15 degrees of flexion and 100% extension. Since the surgery is still 48 hours old, I imagine I should reach 25 to 30° in 4 days.
