Osgood-Schlatter Disease (OSD) is a common overuse injury that affects the knee in growing adolescents, especially those involved in sports that require running, jumping, and sudden changes in direction. It occurs due to repetitive stress on the tibial tuberosity (the bony prominence just below the knee where the patellar tendon attaches), leading to:
- Pain and tenderness below the kneecap
- Swelling around the tibial tuberosity
- A bony lump that may develop over time
- Worsening pain with activity and improvement with rest
It is most common in boys aged 12-15 and girls aged 10-13, coinciding with growth spurts when bones grow faster than muscles and tendons, causing increased tension at the tibial tuberosity.
Physiotherapy is essential in managing OSD because it helps reduce pain, improve flexibility and strength, and prevent long-term complications through:
- Pain Management
- Stretching Exercises
- Strengthening Exercises
- Biomechanical Correction & Gait Training
- Gradual Return to Sport
- Education & Prevention
Early intervention can speed up recovery and prevent chronic knee pain.
