Osgood–Schlatter disease
Signs and symptoms
Intense knee pain is usually the presenting symptom that occurs during activities such as running, jumping, lifting things, squatting, and especially ascending or descending stairs and during kneeling. The pain is worse with acute knee impact. The pain can be reproduced by extending the knee against resistance, stressing the quadriceps, or striking the knee. Pain is initially mild and intermittent. In the acute phase, the pain is severe and continuous in nature. Impact of the affected area can be very painful. Bilateral symptoms are observed in 20–30% of people.
Surgery
Surgical excision may rarely be required in people who have stopped growing. Surgical removal of the ossicles generally results in good outcomes, with symptoms improvement after several weeks.
Rehabilitation
Other exercises can include leg raises, squats, and wall stretches to increase quadriceps and hamstring strength. This helps to avoid pain, stress, and tight muscles that lead to further injury that oppose healing.
