Total Knee Replacement Stretch for Better Flexibility 🦵 . This stretch is one of my favorite ways to gently improve knee motion after a total knee replacement. . Here’s how to do it 👇 1️⃣ Place a sturdy chair near a doorway. 2️⃣ Sit so that your surgical leg’s toe touches the door frame. 3️⃣ Scoot forward until you feel a light stretch across the front of your knee. 4️⃣ As your muscles relax, lean back in the chair and slide your hips forward to increase the stretch. . Hold for about 5 minutes
