Taping the back of your knee requires two or three strips of kinesiology tape applied with careful attention to tension, since the skin behind the knee is thin and folds every time you bend. The goal is to support the hamstring tendons and soft tissue around the popliteal fossa (the hollow behind the knee) without restricting your range of motion. Here’s how to do it properly.
Why the Back of the Knee Needs a Different Approach
The back of your knee is one of the trickiest spots to tape. The skin creases sharply when you bend, which means tape applied with too much stretch will pull uncomfortably or peel off within hours. The area also has a higher concentration of nerve endings and thinner skin than, say, your thigh or calf, so poor application can cause irritation fast.
Most pain at the back of the knee involves either the hamstring tendons (which attach just below the knee on either side), the small stabilizing muscle deep in the joint, or general swelling and strain in the soft tissue. KT tape works here by gently lifting the skin to reduce pressure, improve circulation, and provide light structural feedback to the surrounding muscles.
Prepare Your Skin First
Clean the back of your knee with soap and water or rubbing alcohol, then let it dry completely. KT tape sticks to skin, not to moisture or lotion, so skip any creams or oils beforehand. If you have a lot of hair behind the knee, trimming it short (not shaving, which can cause micro-cuts) will help the tape hold longer.
Cut your strips before you start and round the corners of each piece with scissors. Square corners catch on clothing and begin peeling almost immediately. Rounded edges can add an extra day or two of wear.
Step-by-Step Application
Strip 1: The Anchor Along the Hamstring
Cut one I-shaped strip long enough to run from mid-thigh down to just below the back of your knee. Tear the backing paper at one end and lay that first two inches onto the back of your upper thigh with zero stretch on the tape. This is your anchor, and it should stick flat with no tension at all.
Now bend forward at the waist or prop your foot up on a chair so your leg is slightly bent and the hamstring is in a gentle stretch. Peel away the rest of the backing and lay the strip down along the muscle belly on the outer side of the back of your thigh (this is the biceps femoris, the hamstring tendon you can feel as a firm cord on the outer edge behind your knee). Apply the entire strip with zero stretch, letting the tape simply follow the muscle’s path. Smooth it down with your palm, and the friction from rubbing will activate the adhesive.
Strip 2: The Inner Hamstring (Optional)
If your pain is more central or toward the inner side of your knee, repeat the same process with a second strip running along the inner hamstring. Start the anchor at the upper thigh again with no tension, then lay the strip down the inner side of the back of your thigh, ending just below the inner crease of the knee. You should now have two strips forming a V shape that frames the hollow behind your knee.
Strip 3: The Cross Strip for Direct Support
This shorter strip targets the specific point of pain. Cut a piece about six to eight inches long. Tear the backing paper at both ends but leave those end tabs attached. Peel away only the center section of the backing so you’re holding the strip by its paper-covered tails.
With your knee slightly bent (about 20 to 30 degrees), stretch the exposed middle of the strip to roughly 50 to 75 percent of its maximum stretch and lay it horizontally across the back of your knee, directly over the spot that hurts most. Then lay each tail down with absolutely no tension. This is critical: if the tails are stretched, the ends will recoil and peel up within minutes. Rub the entire strip to set the adhesive.
Getting the Tension Right
The most common mistake when taping the back of the knee is using too much stretch. Here’s a simple way to calibrate: pull the tape as far as it will go, then back off to about half that distance. That’s roughly 50 percent stretch. For the cross strip, you can go slightly higher, up to 75 percent, because it’s a short piece providing targeted support. The long strips running along your hamstrings should have zero stretch along their entire length, with the tape simply laid onto skin that’s already in a stretched position from bending forward.
If the tape feels like it’s pinching or bunching when you bend your knee fully, you’ve applied too much tension. Peel it off and start again. It should feel supportive but not restrictive, like a gentle hand resting on the back of your leg.
How Long It Lasts
A well-applied taping job behind the knee typically holds for two to four days, even through showers. After applying, wait about 30 minutes before getting it wet for the first time so the adhesive fully bonds. Pat the area dry after showering rather than rubbing with a towel.
The back of the knee is a high-movement zone, so expect slightly shorter wear than you’d get on a flatter body part like the shoulder or lower back. If you’re active and sweating heavily, you may need to reapply every two days.
Removing Tape Without Irritating the Skin
The skin behind your knee is sensitive, so don’t just rip the tape off. Peel slowly in the direction of hair growth, rolling the tape back on itself as you go rather than pulling it straight up. If it feels like it’s tugging too hard, apply a small amount of baby oil or mineral oil directly onto the tape surface and let it soak in for about five minutes. The oil breaks down the adhesive and makes removal nearly painless.
Some redness after removal is normal and usually fades within an hour. If you notice a rash, itching, or blistering that lasts longer, you may have a sensitivity to the adhesive. Try a different brand or apply a skin prep barrier product before your next taping session.
What KT Tape Can and Cannot Do Here
Kinesiology tape behind the knee is useful for mild hamstring strains, general posterior knee soreness, minor swelling, and the kind of stiffness that comes from overuse. It provides proprioceptive feedback, meaning it helps your brain stay aware of the joint’s position, which can reduce the chance of awkward movements that aggravate an existing issue.
It won’t stabilize a torn ligament, fix a Baker’s cyst, or replace rehabilitation for a significant injury. If the back of your knee is visibly swollen, locks when you try to straighten it, or gives way under weight, those are signs of something more structural that tape alone won’t address.
