Causes for knee pain

This type of pain can be caused by types of arthritis, injuries, mechanical problems and other problems.

  1. Types of arthritis: More than 100 different types of arthritis exist in the world. The most common types of arthritis which cause knee pain are including:
  • Septic arthritis: In some cases, your knee joint can become infected which is leading to redness, pain and swelling. There is usually no trauma before the onset of pain. This type of arthritis is happening with a fever.
  • Pseudogout: This condition is often mistaken for gout. This condition is caused by calcium – containing crystals which develop in the joint fluid. Knees are the most common joint which is affected by this type of arthritis.
  • Gout: This condition is happening when the uric acid crystals build up in the joint. The gout in the most cases is affecting the big toe but also it can happen in the knee.
  • Rheumatoid arthritis: This is an autoimmune condition which is affecting almost any joint in your body in which are also included our knees. This is a chronic disease. It tends to vary in the severity and it can come and go.
  • Osteoarthritis: This is the most common type of arthritis. It is a wear and tear condition which is happening when the cartilage in the knee deteriorates with the age and use.
  1. Injuries: Here are the most common knee injuries:
  • Patellar tendinitis: This is inflammation and irritation of one or more tendons, the thick and fibrous tissues which are attaching muscles to bones. Cyclists, skiers, runners and people who are involved in the jumping activities are prone to develop inflammation in their patellar tendinitis which is connecting the quadriceps muscles on the front of the thigh to the shinbone.
  • ACL injury: This type of injury is common in people who play soccer, basketball or other sports that require sudden changes in direction.
  1. Mechanical problems: The most common mechanical problems are:
  • Hip or foot pain: When we have foot or hip pain, then we can have changes in the way we walk to spare these painful joints. But this altered gait can place more stress on the knees. There are some cases in which foot or hip can refer pain to the knee.
  • Loose body: In some cases degeneration or injury of the cartilage or bone can cause a piece of cartilage or bone to break off and float in the joint space. This may not cause any problems unless this condition interferes with the knee joint movement.
  1. Other problems: Patellofemoral pain syndrome is a general term which is referring to pain that is arising between the patella and femur. This is common condition in young adults (it is very common in those who have a slight maltracking of the kneecap), athletes and in older adults (they develop this condition as a result of arthritis of the kneecap).
