The moments that give knees away

Plenty of people with sore knees can walk on flat ground without much trouble. It is the in-between moments that hurt: the first step of a staircase, standing up from a low sofa, swinging your legs out of the car, kneeling to reach under the sink. These everyday moves ask the knee to bend under load, and that is often when pain shows up.

This article is about those moments. If you want the bigger picture, including causes such as osteoarthritis, how knee pain is assessed and treatment options, see our full guide to knee pain. Here, the focus is on practical techniques many people use to get through the day with less strain.

Why stairs feel harder than walking

Climbing and especially descending stairs bend the knee further than level walking, and the thigh muscles have to work hard to control your body weight. That increases pressure behind and around the kneecap. Going down is often worse, because the muscles are working to brake each step. Knowing this helps you plan: slower, shorter, well-supported steps reduce the load.

Stair techniques that help

• Use the rail. Let your arms take some of the work. Install a second handrail at home if you can.
• Lead with the right leg. A classic tip from physical therapists: going up, step first with your stronger or less painful leg; going down, lead with the sorer leg. Many people remember it as "up with the good, down with the bad."
• One step at a time. Bring both feet onto each step before moving on when pain is bad. It is slower, but much kinder.
• Place your whole foot on each step, rather than just the ball of the foot.
• Carry less. Make two trips, use a bag across your body, or leave a basket at the bottom and top of the stairs.
• Use a cane correctly if you have one: generally, hold it on the side opposite your painful knee. Ask a physical therapist to check the height and technique.

Chairs, toilets and getting up

• Choose firmer chairs with armrests, and avoid very low, soft sofas when you can.
• Shuffle to the front edge of the seat, place your feet slightly behind your knees, lean forward "nose over toes," and push up with your arms.
• A firm cushion can raise a low seat. A raised toilet seat or grab bar helps many people with painful knees.
• Change position at least every 30 to 60 minutes. Knees often stiffen when held bent for long periods, such as at a desk or in a cinema.

Cars, kneeling and the floor

• Getting into a car: sit down first with your back to the seat, then swing both legs in together. Reverse it to get out. Moving the seat back gives more room.
• Kneeling: use a thick cushion or gardening kneeler, and kneel on your less painful side. A long-handled grabber or a small stool may let you avoid kneeling altogether.
• Getting down to the floor: use a sturdy chair or table for support. Lower yourself onto your better knee, then onto your hands. To rise, reverse the steps using the furniture.

Sleep and night-time aches

Knee pain often feels louder at night. If you sleep on your side, a pillow between your knees can keep them from pressing together and keep your hips level. Back sleepers sometimes prefer a small pillow under the knees, but try not to keep the knee bent all night if it tends to stiffen. Gentle movement before bed, such as a few slow knee bends while sitting, can ease morning stiffness for some people.

Getting around outside

• Wear supportive, cushioned shoes with good grip. Avoid high heels and worn-out soles.
• Choose flatter routes when pain is bad, and slow down on slopes, especially downhill.
• Plan shopping trips with rest stops, use a cart for support, and shop at quieter times.
• Spread active tasks across the day instead of doing everything at once.
• Keep moving overall. Gentle, regular activity such as walking, cycling or water exercise tends to help knees more than resting them completely.

Setting up your home to help

A few changes around the house can save your knees dozens of hard bends a day. Keep everyday items between waist and shoulder height so you aren't crouching into low cupboards. A perching stool in the kitchen lets you prepare food or wash up without standing for long. In the bathroom, grab bars by the toilet and shower, a non-slip mat and a shower seat make transfers safer. Clear trip hazards such as loose rugs and cables, and add night lights on the route to the bathroom. An occupational therapist can suggest other aids if everyday tasks are becoming difficult.

The bottom line

Everyday movements like stairs, low chairs, car seats and kneeling put extra demand on sore knees. Using rails and armrests, leading with the right leg, raising seats, cushioning knees and pacing your day can make a real difference. Keep gently active, and get prompt help for a knee that locks, gives way, swells suddenly or becomes hot and red.
