Injuries:
- Ligament Injuries: Injuries to the anterior cruciate ligament (ACL) are common in athletes and can cause significant pain and instability.
- Meniscus Tears: The meniscus is a cartilage that cushions your knee. A tear can occur due to sudden twists or aging.
- Tendonitis: Inflammation of the tendons can cause pain, particularly in the patellar tendon, which is common in runners and cyclists.
Mechanical Problems:
- Loose Body: Sometimes, injury or degeneration can cause a piece of bone or cartilage to break off and float in the joint space.
- Iliotibial Band Syndrome: The iliotibial band can become tight and rub against the outside of the knee, causing pain.
Types of Arthritis:
- Osteoarthritis: This is the most common type, involving wear-and-tear of the cartilage.
- Rheumatoid Arthritis: An autoimmune condition that can affect any joint in the body, including the knees.
- Gout: This type of arthritis occurs when uric acid crystals build up in the joint.
Other Conditions:
- Bursitis: Inflammation of the bursae (small sacs of fluid that cushion the outside of your knee joint) can cause pain.
- Patellofemoral Pain Syndrome: This is pain at the front of your knee, around your kneecap, often caused by overuse or improper tracking of the kneecap.
