Osgood-Shaltterrs disease is seen in: (PGI Dec 2010)
**Core Concept**
Osgood-Schlatter disease is a common cause of knee pain in adolescents, characterized by inflammation of the patellar ligament at the tibial tuberosity. This condition occurs due to repetitive stress on the growth plate of the tibia.
**Why the Correct Answer is Right**
The disease is associated with the growth spurt during puberty, leading to an increased tension in the patellar ligament. The inflammation and pain are caused by microfractures in the growth plate of the tibia. The condition is more common in boys and is often seen in athletes who participate in sports that involve running and jumping.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because Osgood-Schlatter disease is not typically seen in adults. The condition is specific to adolescents and is related to the growth spurt during puberty.
**Option B:** This option is incorrect because patellar tendinitis, also known as jumper's knee, is a separate condition that affects the patellar tendon, not the patellar ligament.
**Option C:** This option is incorrect because Sinding-Larsen-Johansson syndrome is a similar condition that affects the inferior pole of the patella, not the tibial tuberosity.
**Clinical Pearl / High-Yield Fact**
Osgood-Schlatter disease can be diagnosed clinically by examining the knee for tenderness over the tibial tuberosity and by observing the presence of a bump or swelling in this area. Treatment typically involves rest, ice, and physical therapy to manage pain and promote healing.
**Correct Answer: A. Adolescents.**
