Aim for a total of 10 minutes of knee extension exercises at first, then slowly keep adding time until you are spending at least 30 minutes a day working on terminal knee extension.
Knee extension exercises, especially after surgery, are not going to be comfortable.
When working on terminal knee extension during your knee extension exercises, try to hold the position or stretch for as long as possible. That may be a few minutes or just 20 seconds! The goal is to work to that uncomfortable phase, then let your knee bend and relax for a minute or two, and then go right back to the knee extension exercise again. The more time you can spend in that end range stretch the better!
FEEL: This should feel like a stretch behind your knee, maybe even your calf and hamstring. It can be normal sometimes to feel discomfort in the front of the knee, try to readjust your position if it is not tolerable discomfort. See video for other tips.
FEEL: You will feel this stretch on the back of your knee or in the hamstring muscles.
COMPENSATION: Avoid rounding the back as you perform this, keep your back straight when leaning over.
HOW: Follow this foolproof guide to wake your quad back up! Use a stretch strap or towel and place it around the balls of your feet, holding onto both ends of the towel with your hands. Laying on the ground or on a table with your knee straight and foot supported, attempt to push your knee down and lift your heel off the ground by squeezing your quadriceps muscle until your knee is fully straight. Help your quad lift your heel up by pulling on the strap to lift your heel up at the same time. You should be able to lift it higher with the assistance of the strap. Return to starting position and repeat.
FEEL: Really focus on squeezing your quad. Sometimes touching the muscle, massaging it, or hitting it can help. Think about moving your kneecap up and towards your hip socket. Push your knee down into the ground. Move your shin bone in the shape of a “J” by moving your knee down and your heel up at the same time. Squeeze both quadriceps at the same time to improve the quality of the quad contraction.
COMPENSATION: Do not lift your entire leg off the ground, focus on getting your knee fully straight similar to the other side.
HOW: Get set-up standing with a band around and above the knee with the band anchored in front of you. You will perform this exercise in 3 different positions: with your feet side by side, with your working leg in front of your other leg, and with your working leg behind your other leg. To perform the exercise, put tension on the band so that it wants to pull your knee forward, let your knee bend and your foot go onto the toes followed by squeezing your quad, pushing your heel into the ground, and pushing your knee back until it is fully straight.
FEEL: You will feel your quads working with this exercise and maybe even your glutes. You may also feel a stretch behind your knee in the calf and hamstring region when your knee is straight.
COMPENSATION: Don’t let your butt go back and your hip bend when you straighten your knee. The only thing moving should be your knee going backward!

COMPENSATION: Focus on getting your knee fully straight while keeping the rest of your body still.
