Which condition is characterized by inflammation at the bottom of the patella due to overuse?

The condition characterized by inflammation at the bottom of the patella due to overuse is Sinding Larsen Johansson syndrome. This condition occurs as a result of repetitive stress and strain on the growth plate at the inferior pole of the patella, leading to inflammation and pain. It is often seen in adolescents involved in sports that require jumping or running, as these activities put significant stress on the knees.

In Sinding Larsen Johansson syndrome, the patellar tendon becomes inflamed where it attaches to the lower portion of the patella. This is differentiated from other conditions, as it specifically affects the attachment point at the bottom of the patella itself rather than the surrounding structures. Understanding this distinction is important for proper diagnosis and treatment.

While conditions like patellar tendinitis involve inflammation of the patellar tendon itself, and Osgood-Schlatter disease relates to inflammation at the tibial tuberosity, they do not specifically target the bottom of the patella. Runner's knee, which can encompass various knee pain syndromes, is not as precisely defined and does not specifically refer to inflammation at the bottom of the patella. Sinding Larsen Johansson syndrome stands out for its specific involvement of the inferior patellar region due to overuse.
