Knee stability with a band is a small knee bend on one leg while a resistance band pulls that knee outward. You rest one hand on a chair and keep the kneecap in line with your second toe as the band tries to drag it sideways. It trains the thigh and the muscles around the hip to steady the knee over the foot. The band sits on the outer side of the knee here, the opposite of versions where it pulls the knee inward.

How to do the knee stability with a band

Fix one end of a resistance band at knee height, for example around the leg of a heavy table, on the outer side of the leg you will work.
Loop the free end around that knee. Stand with a sturdy chair on the side of your other leg and rest that hand on the chair back.
Side-step toward the chair until you feel a light, steady tug on the outside of the knee.
Put your weight on the banded leg and raise the other foot behind you by bending that knee.
Slowly bend the standing knee a little, holding the kneecap over your second toe while the band works to draw it outward. Straighten slowly and repeat.
Finish your reps, then set up facing the other way if your program includes both legs.

What you should feel

Work in the front of the thigh and around the hip of the standing leg, with the inner thigh helping to stop the knee drifting out. Your hand only rests on the chair.

Common mistakes

Giving in to the band, so the knee swings out and points past your little toe.
Letting the foot tip so your weight sits on its outside edge.
Leaning your trunk sideways to fight the band.
Choosing a band too strong for you to hold the knee line.

How often

Programs often begin with 2 to 3 sets of 6 to 10 on each side, using a light band. Your physio will adjust this.

Stop and check with your physio if

Sharp pain in the knee, pain on the inner or outer side of the knee that builds with each bend, or the knee gives way.
You wobble enough that a fall seems possible, even holding the chair. Lower the lifted foot to the floor and stop.
You feel dizzy, lightheaded, faint or sick, or the room seems to spin. Hold your support, sit down and get medical advice the same day before you practice again. If you faint, it does not settle within a few minutes of sitting still, your vision suddenly blurs or goes double, or you cannot stand or walk steadily, call emergency services.

From the clinic

Keep one hand on the chair throughout, and use a chair heavy enough not to move, or stand at a kitchen counter. Before each set, check the band for splits or worn spots and give the anchor a hard tug, because a band that slips or breaks will jerk your knee sideways and can pull you off balance. Wear flat shoes that fit well and grip the floor, not socks, tights or bare feet. If you have had a fall in the last 12 months or feel unsteady on one leg, have someone nearby and ask your physio before you start.

The single leg mini squat with band is the same exercise with the band pulling the knee inward, and your physio will pick the direction your knee needs. If the knee drifts even with a light band, practice the small bend without it first, holding the chair with both hands.

After a knee fracture or knee surgery, including a knee replacement, follow your surgeon's or physio's plan, and start this exercise only when they have cleared you. After a knee ligament repair or reconstruction, or meniscus surgery, ask them as well when a sideways band pull is right for you. If you have had a hip replacement, get the go-ahead from your surgeon or physio before you try this exercise. Some operations limit this kind of work for the first months, so the timing depends on your surgery.
