In many people, the patella is malaligned, and instead of running in the middle of the trochlea groove it runs too far over to the outer (lateral) side. This is called patellar maltracking. With normal patellar maltracking, the forces passing through the patella onto the front of the knee are dissipated evenly.

Constitutionally, it can appear, that due to lacking muscular guidance or as a consequence of former kneecap injuries, the kneecap drifts outwardly from its slide bearing. This is called patellar lateralization (outward drifting of the kneecap) or patellar subluxation.
M25.561 - Pain in right knee.
The term patellofemoral pain syndrome refers to pain that occurs in the front of the knee. Sometimes called “runner's knee” because it is common in people who play sports, this disorder affects the area of the lower femur (thighbone) where the patella (kneecap) slides through a groove.
Lateral patella tilt is when the knee cap is not sitting properly in the groove at the bottom of the thigh bone (femoral groove) and is tilted towards the outside (lateral) of the knee.
Weak thigh muscles. Tendons, ligaments, or muscles in the leg that are too tight or too loose. Activities that stress the knee again and again, especially those with twisting motions. A traumatic injury to the knee, such as a blow that pushes the kneecap toward the outer side of the leg.
It is caused by imbalances in the forces controlling patellar tracking during knee flexion and extension, particularly with overloading of the joint. Risk factors include overuse, trauma, muscle dysfunction, tight lateral restraints, patellar hypermobility, and poor quadriceps flexibility.
A patellar subluxation means that the kneecap has briefly slid out of its normal place in that groove. In most cases the kneecap moves towards the outside of the body when it slides out of place.
Lateral articular facet (facies articularis lateralis) is the larger of two shallow depressions on the posterior surface of the patella, which articulates with the lateral condyle of femur.
Conditions Treated Lateral release is a minimally invasive surgery used to correct an excessive patellar tilt. It involves cutting through a tight retinaculum so that the kneecap can slip properly into its groove, thereby restoring its normal alignment.
Treatment of Lateral Patellar Compression Syndrome Treatment options include both non-surgical and surgical methods. Non-surgical treatment consists of rest, ice, compression and elevation (RICE protocol); all assist in controlling pain and swelling.
Put your affected leg about a step behind your other leg. Keeping your back leg straight and your back heel on the floor, bend your front knee and gently bring your hip and chest toward the wall until you feel a stretch in the calf of your back leg. Hold the stretch for at least 15 to 30 seconds. Repeat 2 to 4 times.
Conservative treatment is usually successful, although full recovery may take time. Over the counter anti-inflammatory medications and taping/bandaging of the superior pole of the patella to relieve pressure of the infrapatellar fat pad have proven to result in high treatment success rates.
