Knee stretches can help improve the flexibility of the muscles surrounding the knee.

These muscles include:

• front and back thigh muscles — the quadriceps and hamstrings
• inner and outer thigh muscles — the adductors and abductors
• buttocks
• calf muscles

Strengthening these muscles may help decrease stress on the knee joint and absorb shock.

Stretching, especially after exercising, can help increase flexibility and range of motion of the knee joint. It can also help reduce soreness and the risk of injury.

The American Academy of Orthopaedic Surgeons recommend the following exercises to help strengthen the muscles around the knee and increase the range of motion.

The exercises may suit people after a knee injury or surgery. However, a person should talk to a healthcare provider before attempting them.

Before starting the exercises, it is crucial to warm up gently with low-impact exercises, such as walking or riding an exercise bike for 5–10 minutes.

Anyone who experiences pain in the knee when stretching should consider consulting a healthcare provider to check what stretches are safe for them.

A person can take several steps to help prevent injury and relieve knee pain.

Tips for maintaining knee health

Steps people can take to protect and maintain knee health include:

• moving about and taking regular exercise
• doing low-impact exercise, such as swimming or walking, if recovering from knee pain
• using a knee wrap or bandage for extra support
• wearing shoes that offer proper support during physical activity
• doing warm-up and cool-down stretches before and after exercise
• increasing exercise intensity gradually

Losing weight to ease pressure on the knees may reduce inflammation and increase knee function in adults with obesity who have knee osteoarthritis.

Exercises to help prevent knee injuries

If a person is healthy and active, other exercises that may help prevent knee injuries include:

• running drills, such as zigzag running and changing directions
• core strength exercises, such as the plank
• lunges
• other knee strengthening exercises

Relieving knee pain

To help relieve knee pain, people may find the following actions help:

• taking nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce swelling
• applying a warm compress, unless the knee injury is new
• following the RICE method — rest, ice, compression, and elevating the knee may benefit people in rehab for acute injuries

Knee exercises should not cause additional or worse pain.

People should stop any knee exercises and see their doctor if they experience:

• severe pain
• swelling
• no improvement after a few weeks
• inability to move knee or put weight on it
• knee locks or clicks painfully, or gives way

A doctor may need to carry out a physical exam or tests, such as X-rays or MRI scans, to determine the cause and diagnose the condition.

People may need to see a physical therapist for a specialized stretching program.
