Full Answer

Some of the most common injuries that cause knee pain include an anterior cruciate ligament injury, a torn meniscus, bursitis and tendonitis, Mayo Clinic explains. Anterior cruciate ligament injuries are common in people who play sports, and a torn meniscus can happen when the knee is suddenly twisted. Knee bursitis is an injury having to do with inflammation around the knee, and tendonitis usually affects individuals who put pressure on their knees, such as skiers, runners and cyclists.

A number of mechanical problems can cause knee pain, including a loose body in the knee, iliotibial band syndrome or a dislocated knee cap, Mayo Clinic explains. A loose body may consist of bone or cartilage that floats around in the space behind the knee. Iliotibial band syndrome is a condition where a ligament becomes too tight against the knee, and a dislocated knee cap occurs when the patella shifts from its position.

Arthritis also causes knee pain, and there are more than 100 types of arthritis, states Mayo Clinic. The types of arthritis that most commonly affect the knee include osteoarthritis, rheumatoid arthritis and gout.
