[Health Channel/Comprehensive Report] Pain around the patella, be careful is a warning signal from the overload of the body.

Wu Yicheng, a specialist in sports medicine and rehabilitation at Lianxin International Clinic, pointed out that patellofemoral syndrome is an injury caused by overuse and is one of the most common running injuries. This disease may occur in all age groups.

Its risk factors include joint weight loading beyond muscle load, increased patella angulation, and malalignment of the bones, among others.

Wu Yicheng posted on his Facebook fan page "Dr. Wu Yicheng-Sports Medicine and Rehabilitation Medicine" and his personal website that pain around or behind the patella is an injury caused by overuse, which may be caused by a variety of factors, including biomechanical changes, poor alignment of the lower limbs, Muscle imbalances and more.

Many people call it "patella patella", and to avoid this condition, you can do some low-stress exercises, such as swimming and yoga.

In addition, you can also wear appropriate insoles and use appropriate support equipment to improve poor alignment.

Wu Yicheng said that pain in the front of the knee accounts for 20-40% of all knee problems, and patellofemoral syndrome is one of the most common running injuries in sports medicine.

The disease can occur in all age groups, but the general prevalence is 22.7% for adults and 28.9% for adolescents.

Women are more prone to the disease than men.

Pain in the front of the knee can be caused by trauma (such as damage to the cartilage or subchondral bone caused by landing on the knee), but most cases develop gradually.

He noted that risk factors for patellofemoral syndrome include the following:

●Recent increase or change in training/activity: joint load exceeds muscle load during exercise, such as running, squatting, lunging.

Patella-related problems, increased patella angle (Q angle).

• Malalignment issues (eg, increased femoral pronation, inwardly facing patella, valgus valgus, externally rotated tibia, varus foot, etc.).

●X-shaped or O-shaped legs.

●Family medical history.

●Peripheral strength imbalance, such as relative to the lateral and medial muscle groups, the quadriceps is too tight, the pelvis is tilted forward, and the lateral iliotibial band is too tight, etc.

Dysfunction of the gluteus medius, the external hip rotator group, can lead to decreased hip control and increased femoral adduction and internal rotation.

Wu Yicheng said that patellofemoral syndrome is related to the history of anterior knee pain after squatting, anterior knee pain when running, climbing stairs or going downstairs, protruding knee or dislocation, etc. As for the sound of joint friction, he said, whether there is joint friction sound Not helpful for diagnosis, as most healthy women and nearly half of healthy men may also have a fricative on examination.

If other diseases are suspected or the patient fails to improve with basic conservative treatment, imaging studies are recommended. Most radiological findings will be normal, but structural abnormalities need to be ruled out.
