[3] Patellofemoral pain syndrome is the most common cause of knee pain, affecting more than 20% of young adults. [1] [2] It occurs about 2.5 times more often in females than males. [2]
Chondromalacia patellae (also known as CMP) is an inflammation of the underside of the patella and softening of the cartilage. The cartilage under the kneecap is a natural shock absorber, and overuse, injury, and many other factors can cause increased deterioration and breakdown of the cartilage. The cartilage is no longer smooth and therefore ...
Osgood–Schlatter disease (OSD) is inflammation of the patellar ligament at the tibial tuberosity (apophysitis) [3] usually affecting adolescents during growth spurts. [5] It is characterized by a painful bump just below the knee that is worse with activity and better with rest. [3] Episodes of pain typically last a few weeks to months. [6]

Patellar tendinitis, also known as jumper's knee, is an overuse injury of the tendon that straightens the knee. [1] Symptoms include pain in the front of the knee. [1] Typically the pain and tenderness is at the lower part of the kneecap, though the upper part may also be affected. [2] Generally there is no pain when the person is at rest. [2]
Patellar subluxation can be caused by osseous abnormalities, such as incorrect articulation of the femoral groove with the patella, trochlear dysplasia, or patella alta, which is a distance of greater than 20 mm between the tibial tubercle and the trochlear groove. It can also result from soft-tissue abnormalities, such as a torn medial ...
Frequency. 6 per 100,000 per year [4] A patellar dislocation is a knee injury in which the patella (kneecap) slips out of its normal position. [5] Often the knee is partly bent, painful and swollen.
