Patient question

What knee exercises can I do at home without equipment?

Dr. Pablo GelberOrthopaedic Knee Surgeon

Quick answer

Most painful or weak knees benefit from a short daily routine of thigh tightening, straight-leg raises, bridges, side-lying leg lifts and controlled sit-to-stands, done without pain flaring. Start gently and build repetitions over weeks, advises Doha knee surgeon Dr. Pablo Gelber at Aman Hospital, and get examined if the knee locks, gives way or swells.

A starter routine

These exercises work the thigh, hip and buttock muscles that protect the knee. Do them once or twice a day, slowly, on a mat or firm bed.

Quad sets: sit with the leg straight, press the back of the knee down into the floor and hold for five seconds, ten times
Straight-leg raise: lying on your back, tighten the thigh and lift the straight leg to the height of the other bent knee, ten times
Bridge: lying on your back with knees bent, lift your hips by squeezing the buttocks, ten times
Side-lying leg lift: lying on your side, lift the top leg slightly behind you, ten times each side
Sit-to-stand: from a firm chair, stand up and sit down slowly without using your hands, eight to ten times
Calf raises: holding a counter, rise onto your toes and lower slowly, fifteen times

How to progress

Begin with one set of each and add a set every week or so as the exercises become easy. Mild discomfort during exercise is acceptable if it settles within a day and the knee does not swell. Pain that is sharp, or that is worse the next morning, means you should reduce the load.

Once the basics are comfortable, a physiotherapist can add step-ups on the stairs, shallow squats, single-leg balance and later resistance bands. Using a staircase in your building or the stairs at home is a simple way to progress without a gym.

When home exercises are not enough

Exercise is a first-line treatment for many knee problems, including arthritis and front-of-knee pain. It is not a substitute for assessment when the knee has a mechanical or structural problem. See a knee specialist if:

The knee locks, catches or will not straighten
It gives way or feels unstable, especially after a twist or a pop
It swells repeatedly after activity
Pain is not improving after around six weeks of regular exercise

Seek urgent care for a hot, red, very swollen knee with fever, or if you cannot bear weight after an injury.

Frequently asked questions

Should I do the exercises if my knee hurts?

Mild, short-lived discomfort is usually fine. Stop or reduce the exercise if pain is sharp, builds during the session, or leaves the knee more swollen the next day.

Is walking enough exercise for my knee?

Walking is good for general health and joint nutrition, but it usually does not build enough thigh and hip strength on its own. Adding a few targeted exercises makes a noticeable difference for many people.
