Can you list the top facts and stats about Osgood–Schlatter disease?
Summarize this article for a 10 year old
Osgood–Schlatter disease (OSD) is inflammation of the patellar ligament at the tibial tuberosity (apophysitis)[3] usually affecting adolescents during growth spurts.[5] It is characterized by a painful bump just below the knee that is worse with activity and better with rest.[3] Episodes of pain typically last a few weeks to months.[6] One or both knees may be affected and flares may recur.[3][5]

Risk factors include overuse, especially sports which involve frequent running or jumping.[3] The underlying mechanism is repeated tension on the growth plate of the upper tibia.[3] Diagnosis is typically based on the symptoms.[3] A plain X-ray may be either normal or show fragmentation in the attachment area.[3]
Pain typically resolves with time.[3] Applying cold to the affected area, rest, stretching, and strengthening exercises may help.[3][6] NSAIDs such as ibuprofen may be used.[5] Slightly less stressful activities such as swimming or walking may be recommended.[3] Casting the leg for a period of time may help.[6] After growth slows, typically age 16 in boys and 14 in girls, the pain will no longer occur despite a bump potentially remaining.[5][7]
About 4% of people are affected at some point in time.[4] Males between the ages of 10 and 15 are most often affected.[3] The condition is named after Robert Bayley Osgood (1873–1956), an American orthopedic surgeon, and Carl B. Schlatter (1864–1934), a Swiss surgeon, who described the condition independently in 1903.[1][8]
