Overview
Knee pain is a common problem for people of all ages. It may be the result of an injury, such as meniscal tears and ligament injuries. Medical conditions including arthritis, gout and infections, may also be the cause of your discomfort.
To get a better idea of why your knee hurts, let’s take a look at how it works. Your knee is the largest joint in your body, and it works a lot like a hinge. Three bones come together to form the joint: the lower end of the thigh bone (the femur), the upper end of the shin bone (the tibia), and then the kneecap (the patella) right above where the long bones meet. Tough bands called ligaments help keep everything in place and stable. Cartilage provides cushioning, keeps bones from rubbing together, and absorbs the shock of walking, running, and jumping. Your body also produces a natural lubricating fluid called synovium that minimizes friction in the joint. Any damage or disease in these structures can lead to knee pain.
Some causes of knee pain are obvious while others may require expert examination and special investigations to diagnose. It's important to consult with a healthcare professional for accurate diagnosis and treatment options if you suspect any knee issues
Common Causes of Knee Pain
Knee Osteoarthritis
Osteoarthritis is a degenerative process where the cartilage in the joint gradually wears away. It often affects middle-aged and older people. Osteoarthritis may be caused by excess stress on the joint such as repeated injury or being overweight.
Ligament Tears (ACL, PCL, MCL, LCL)
A sprained or strained knee ligament or muscle is usually caused by a blow to the knee or a sudden twist of the knee. Symptoms often include pain, swelling, and difficulty in walking.
Meniscus Injuries/ Tears
Trauma to the knee can tear the menisci (pads of connective tissue that act as shock absorbers and also enhance stability). Cartilage tears can often occur with sprains. Treatment may involve wearing a brace during an activity to protect the knee from further injury. Surgery may be needed to repair the tear.
Rheumatoid Arthritis
An autoimmune disorder that primarily affects joints, causing inflammation, pain, and stiffness. It can also impact other organs. Treatment typically involves medications, lifestyle changes, and sometimes surgery.
