Knee rehab exercises are a great way to reduce knee pain and instability as well as improve strength and flexibility

Knee rehab exercises aim to increase muscle strength, flexibility and control. This helps reduce knee pain, stiffness, weakness, instability and swelling caused by injuries, long-term knee problems and surgery.

Here you will find a general programme of advanced-level knee rehab exercises working on strength, flexibility and balance. They target all the important leg muscles, the quads, hamstrings, buttocks and calf muscles.

If you have not already tried the beginners or intermediate exercises, do start there first. Exercises should feel challenging but not aggravate your pain. Find out more in the Exercising at the Right Level section.

Advanced Knee Rehab Exercises

You should always see your doctor before you start any knee rehab to get an accurate diagnosis, but once you get the all clear, you’re ready to begin. 

1. Squats With A Weight

Purpose: Squats are one of the best ways to improve knee strength and abolish pain.  They target the hamstrings, quads and buttock muscles

Starting Position: Stand upright with feet hip width apart, toes pointing forwards. 

Action: Slowly squat downwards as far as is comfortable without letting your knees go forwards over your toes. Then return to starting position

Repetitions: 10-30 repetitions

Top tips: Don’t let your knees drop inwards, keep your kneecap in-line with your second toe

Progression: Hold a weight e.g. a medicine ball and as you squat down reach forwards as shown in the video

2. Bridging: Stage 2

Purpose: Great knee rehab exercise to strengthen the hamstrings, quads and buttock muscles. If you haven't already done Bridging: stage 1, start there.

Starting Position: Lie on your back with both knees bent about 90° and your feet on the floor/bed. Knees should be slightly apart (tennis ball width)

Action: Clench your buttocks and lift your bottom off the bed as high as you can without arching your back. Then lift one leg up. Hold for 3-5 seconds and slowly lower

Repetitions: Repeat 10-25 times, 1-2x daily

Top Tips: 1. Keep your back straight – don’t let it arch as you lift up, it should be your bottom doing the work
2. Don’t hold your breath – keep breathing normally
3. Keep your knees tennis ball width apart – don’t let them drop out or lock them together
4. Don’t let your hips drop during the exercise – keep them up as high as you can

Progression: Use resistance bands to make the exercise harder - either loop a band around your lower thighs and gently push out against the band as you lift, or loop a band across your thighs and anchor it in each hand

3. Chair Squats

Purpose: Increase knee strength (quads, hamstrings, glutes)

Knee Rehab Exercises: Squats are a great way to reduce knee pain.  These chair squats are a great variation on traditional squats.

6. The Clam: Stage 2

What Next?

Knee rehab exercises are one of the most important parts in recovering from pain. If these exercises seem too challenging or you are just starting out, try our beginners and intermediate knee rehab exercises first.

Another effective way to reduce many causes of knee pain is to improve the flexibility of knee muscles by stretching. Most people have tighter muscles than they should. To see if you have a problem check out some simple stretching tests or skip straight to stretching exercises.

It always helps to know what is causing your pain to ensure the knee rehab exercises are suitable for you.  Visit the knee pain diagnosis section for help or find out more about the most common causes of knee pain.
