Have you ever had a bruised knee? And ever wondered why? If so, here’s the answer for you.
Knee bruising occurs when small blood vessels under the skin rupture, but the skin remains intact. Blood leaks from these damaged blood vessels into the surrounding tissue, causing it to turn into a bruise.
There are three types of bruises:
• Subcutaneous occurs under the skin.
• Intramuscular nerves occur in the lower extremities
• Bone bruises are injuries to the inner bones
A bruise on the knee can be caused by damage to the skin, ligaments, ligaments or bones of the knee. For example, a knee injury can cause a torn frontal ligament in addition to a bruise.
Causes of knee bruises
Knee bruises are usually caused by direct and indirect bumps on the body involving something that causes erosion. This can happen due to a fall or when a person kneels on a hard object. Bruising can also be related to other types of injuries, such as: fractures, broken bones, torn tendons or misalignment of joints. Older people are more likely to have bruises than younger people.
How to treat a bruised knee
One can treat bruised knee at home using the RICE method. This method includes:
• Relax the knee joint
• Cool the knees with a pack or ice pack for 20 minutes at a time, several times a day
• Gently wrap your knees with a soft bandage
• Raise the knees above the level of the heart if possible, to prevent blood from pooling to the knees.
Don’t apply ice directly to the skin or try to drain the bruise with a needle. If there is a large lump that does not go away after several days, you should seek medical help.
A bruised knee will heal in about 2 to 4 weeks. A bone bruise can take one to two months or longer if the bruise is large.
When to seek medical help?
One should consult a doctor if:
• Knee bruises do not improve in 2 to 4 weeks
• A bruise develops into a hematoma on the knee that does not subside after a few days
• Your knee shows signs of a broken bone or serious injury, such as severe pain or swelling,
• Knee red or purple or other color that is not caused by knee injury and show signs of infection such as: swelling, pus and warmth.
These signs can be caused by severe symptoms that need immediate treatment.
