Apophyses are growth plates made up of cartilage that can be found throughout a child’s body, functioning as attachment sites between muscles and tendons.
When a young athlete participates in physical activities or sports where a specific set of muscles is constantly overused, such as the thigh muscles while running or jumping, the apophyses can weaken. The repetitive stretching of the apophysis can cause microscopic cracks in the cartilage growth plate, resulting in pain and inflammation.
Sinding Larsen Johansson syndrome (SLJ) is a condition that occurs at the bottom of the kneecap due to the additional stress of the apophysis being repetitively stretched during physical activities or sports. This condition can also occur from a direct, blow, fall, or one sudden jump.
Sinding Larsen Johansson syndrome (SLJ) is a condition affecting children younger than children affected with Osgood-Schlatter disease, generally between the ages of seven and thirteen, before adolescence. For more information, please feel free to ask Dr. Jimenez or contact us at (915) 850-0900.
