Pain – knee
Simple causes of knee pain often clear up on their own with self care. Being overweight can put you at greater risk for knee problems.
Knee pain can be caused by:
Anterior knee pain
Baker’s cyst— a fluid-filled swelling behind the knee that may occur with swelling (inflammation) from other causes, like arthritis
Bursitis— inflammation from repeated pressure on the knee, such as kneeling for long periods of time, overuse, or injury
Connective tissue disorders such as
Dislocation of the kneecap
Iliotibial band syndrome — a hip disorder from injury to the thick band that runs from your hip to the outside of your knee
Infection in the joint
Knee injuries — an
anterior cruciate ligament injuryor medial collateral ligament injurymay cause bleeding into your knee, which makes the pain worse
Tendinitis— a pain in the front of your knee that gets worse when going up and down stairs or inclines
Torn cartilage (a
meniscus tear) — pain felt on the inside or outside of the knee joint
Torn ligament (ACL tear) — leads to pain and instability of the knee
Strainor sprain— minor injuries to the ligaments caused by sudden or unnatural twisting
Less common conditions that can lead to knee pain include
t answer is E. If you have one of these knee injuries, you will often feel the symptoms right away. You may also have knee swelling, knee pain when walking, or locking or catching of the knee. If you have any of these symptoms, call your doctor right away.
For knee pain that has just started:
- Rest and avoid activities that aggravate your pain, especially weight bearing activities.
- Apply ice. First, apply it every hour for up to 15 minutes. After the first day, apply it at least four times per day.
- Keep your knee raised as much as possible to bring any swelling down.
- Wear an ace bandage or elastic sleeve, which you can buy at most pharmacies. This may reduce swelling and provide support.
- Take acetaminophen for pain or ibuprofen for pain and swelling.
- Sleep with a pillow underneath or between your knees.
For knee pain related to overuse or physical activity:
Always warm up before exercising and cool down afterward. Stretch your quadriceps and hamstrings.
Avoid running straight down hills — walk down instead.
Bicycle or swim instead of run.
Reduce the amount of exercise you do.
Run on a smooth, soft surface, such as a track, instead of on cement.
Lose weight if you are overweight. Every pound that you are overweight puts about 5 extra pounds of pressure on your knee cap when you go up and down stairs. Ask your health care provider for help losing weight.
If you have flat feet, try special shoe inserts and arch supports (orthotics).
Make sure your running shoes are made well, fit well, and have good cushioning.
Tips to relieve knee bursitis pain:
Use ice three to four times a day for the first 2 or 3 days. Cover your knee with a towel and place ice on it for 15 minutes. Do not fall asleep while using ice. You can leave it on too long and get frostbite.
Try not to stand for long periods of time. If you must stand, do so on a soft, cushioned surface. Stand with an equal amount of weight on each leg.
When you sleep, do not lie on the side that has bursitis. Place a pillow between your knees when you lie on your side to help decrease your pain.
Wear flat shoes that are cushioned and comfortable.
If you are overweight, losing weight may help.
