- Chondromalacia patella occurs when the cartilage of a person's kneecap softens. (medicalnewstoday.com)
- Chondromalacia patella is when the cartilage of the underside of the kneecap begins to break down. (medicalnewstoday.com)
- Chondromalacia patella can develop gradually, when the cartilage on the underside of a person's knee wears away, causing grinding and rubbing of the kneecap over the knee joint during movement. (medicalnewstoday.com)
- If any of these structures fail to function as they should, it can cause the kneecap to rub on the femur below. (medicalnewstoday.com)
- Patellofemoral" refers to the area between the kneecap (patella) and the thigh bone (femur). (ottobock.com)
- Arthrosis of the patella is often triggered by an injury, e.g., if the kneecap is broken or dislocated, or after a cruciate ligament injury, or due to a patellar tracking disorder. (ottobock.com)
- But it can also be triggered by a misaligned kneecap (patella), faulty position of the feet or excessive strain. (ottobock.com)
- The kneecap (patella) is located above the knee joint and moves most when you bend your knee or extend your leg. (ottobock.com)
- If the patella is misaligned or too much strain or weight is placed on the joint, it can slip out of place, causing irritation between the kneecap and the knee joint. (ottobock.com)
- Also known as Patella Femoral Pain Syndrome and Patella Femoral Compression Syndrome, it is characterized by pain around the kneecap that increases with activities. (sports-injury-info.com)

Groove17
- The patella rests in a groove formed by the femur. (healthpartners.com)

- With the knee extended 0°, the patella rides laterally within the trochlear groove and is not in direct contact with the trochlear cartilage. (medscape.com)
- The patella normally rides in a groove within the femur (thigh bone) in the knee (Figure 1). (acvs.org)
- The patella is less likely to slip out of place when your knee joint is bent at an angle greater than 30°, because it then rests more firmly in the groove. (ottobock.com)
- Boiled down to the basics, it centers around the patella, and the way that it tracks within the femoral groove. (sports-injury-info.com)
- The femur has a shallow groove in which the patella moves up and down during knee flexion and extension (bending and straightening). (sports-injury-info.com)
- When you contract your quadriceps, the patella moves along the femoral groove. (sports-injury-info.com)
- With patella femoral compression syndrome, the patella is not quite centered within the groove. (sports-injury-info.com)
- As the quads contract, the patella moves along the groove, but if it is not aligned correctly, there are areas of greater pressure, and areas of lesser pressure. (sports-injury-info.com)
- Two examples of structural alignments include a shallow femoral groove, or a small patella. (sports-injury-info.com)
- Both of these factors can contribute to patella femoral syndrome, yet there is very little that can be done to change the depth of the groove or the size of the patella without surgery. (sports-injury-info.com)
- The patella slides up and down in a groove on your femur as you bend and extend your knee. (scoi.com)
- Therefore the quadriceps muscles control the movement of the patella through the groove at the end of the femur. (fleetfeet.com)
- This results in the patella being pulled to the outside and dragging through the groove at the end of the femur. (fleetfeet.com)
- The patella articulates anteriorly to the femoral condyles in the region of the intercondylar fossa (trochlear groove). (medscape.com)

- The quadriceps muscle, the patella and its tendon form the "extensor mechanism" and are normally well-aligned with each other. (acvs.org)
- This may be because females have a larger Q angle, which measures the angle between the quadriceps muscles and the patella tendon. (medicalnewstoday.com)
- The quadriceps muscles are the large muscles on the front of your upper leg, and all four connect to the patella, and then the patellar tendon connects them to the lower leg. (sports-injury-info.com)
- The tendon of the quadriceps femoris completely encompasses the patella. (medscape.com)
Tibia at the knee1
- Women generally have wider hips, which puts the femur at a bigger angle as it meets the tibia at the knee, creating a greater static valgus Q-angle. (acefitness.org)

Iliotibial band2
- [ 5 ] Fibers connecting the iliotibial band to the patella are referred to as the iliopatellar band. (medscape.com)
- During knee flexion and extension the iliotibial band moves back and forth over a prominence on the outside of the femur. (fleetfeet.com)
Subluxation2
- Instability symptoms, such as giving way and loss of confidence in the extremity when twisting or turning on the knee, suggest ligamentous injury or subluxation of the patella. (msdmanuals.com)

Anatomical1
- To be clear: in the absence of a measurably significant discrepancy in the anatomical length of the femur and tibia, the problem is corrected with the enforcement of proper technique under the bar - not a shim under the foot. (startingstrength.com)
Extensor mechanism1
- The patella provides a significant mechanical advantage to the knee extensor mechanism, allowing the knee to extend with a smaller contractile force of the quadriceps. (medscape.com)
