What is Knee Pain?
Knee pain is a common condition affecting individuals from different age groups. It not only affects movement but also impacts the quality of life of the individual. An injury or disease of the knee joint or any structure surrounding the knee can result in knee pain. A precise diagnosis of the underlying cause is important to develop an appropriate treatment plan.
Causes of Knee Pain
Some of the common causes for knee pain include:
- Arthritis: a condition associated with inflammation of the joint .
- Knee ligament injuries.
- Torn meniscus.
- Patellar tendonitis: inflammation of the patellar tendon which connects the kneecap to the shinbone .
- Chondromalacia patellae: softening of the articular cartilage on the under surface of the kneecap causing knee pain.
- Dislocated kneecap.
- Baker’s cyst: a fluid-filled swelling in the back of the knee which usually results from another problem such as a meniscus tear.
- Knee bursitis: inflammation of the bursae, small fluid-filled sacs located around the joints, usually between a tendon and the bone.
- Plica syndrome: results from inflammation of the synovial tissue of the knee causing knee pain and swelling.
- Osgood-Schlatter disease: caused by irritation of the growth plate at the front of the knee joint and is more common in adolescents
- Osteochondritis dissecans: characterized by detachment of a cartilage fragment and a thin layer of the bone from the end of a bone due to inadequate blood supply; these fragments may either stay in place or slide around the joint causing pain and joint instability.
- Gout: characterized by sudden, severe attacks of joint pain, with swelling and redness around the joint, caused by accumulation of uric acid crystals in the joints.
