Osteoarthritis of the Knee
What is Osgood-Schlatter’s disease?
Osgood-Schlatter’s disease is a common condition seen in growing adolescents, particularly active boys. It causes pain, swelling, and tenderness over the bony bump just below the kneecap (tibial tuberosity). This discomfort is linked to growth and activity levels during puberty. Physiotherapy is often an important part of treatment, helping to reduce pain and manage the condition safely while allowing young athletes to stay active.
How does Osgood-Schlatter’s disease develop?
The condition is caused by repeated stress on the quadriceps muscles, which are located at the front of the thigh. These muscles straighten the knee by pulling on the patella (kneecap). The patella is connected to the top of the shin bone by a thick band of tissue called the patellar tendon.
When the quadriceps are overused—especially during activities that involve running, jumping, or kicking—excessive strain is placed on the point where the patellar tendon attaches to the shin bone. This repeated stress can cause irritation, inflammation, and pain. In some cases, small bone fragments may form at the site, and rarely, tiny fractures can develop.
Osgood-Schlatter’s disease is most common in teenagers who play high-impact or repetitive sports. It typically occurs during growth spurts and is rarely seen after the age of 16, once the bones and tendons have fully matured.
What are the symptoms of Osgood-Schlatter’s disease?
The primary symptom of Osgood-Schlatter’s disease is pain over the bony prominence just below the kneecap (tibial tuberosity). The intensity of pain may vary day to day and is often worse during or immediately after activity, easing with rest. Symptoms usually last several months but can persist until the adolescent finishes growing.
A small, tender bony bump may also develop at the site where the patellar tendon attaches to the shin bone. Other common symptoms include:
- Reduced range of movement in the knee
- Gait or walking difficulties
- Muscle weakness around the knee
- Balance problems
What should I do if my child has Osgood-Schlatter’s?
If your child develops a painful lump below one or both kneecaps, arrange a physiotherapy appointment promptly. While waiting for treatment:
- Limit participation in high-impact sports and activities
- Apply ice to the painful area for 10–15 minutes at a time, using a bag of frozen peas or crushed ice wrapped in a damp cloth, to help reduce pain and swelling
What shouldn’t I do if my child has Osgood-Schlatter’s disease?
Do not encourage your child to continue exercising through the pain. Overloading the affected knee can worsen the condition and prolong recovery. Following a structured physiotherapy plan and allowing adequate rest are essential for healing and safe return to sport.
Physiotherapy for Osgood-Schlatter’s disease
A physiotherapist can accurately assess your child’s knee pain and determine the severity of Osgood-Schlatter’s disease. Based on this assessment, a tailored treatment plan will be developed to relieve pain, improve knee function, and support safe activity. Physiotherapy may include:
Depending on your needs, physiotherapy treatment may also include:
- Electrotherapy – to reduce pain and inflammation
- Hydrotherapy – gentle water-based exercises to improve movement without stressing the knee
- Range of movement exercises – to maintain flexibility and mobility in the knee
- Exercise programmes – strengthening routines for the quadriceps and surrounding muscles to support the knee
Could there be any long-term effects from Osgood-Schlatter’s disease?
Osgood-Schlatter’s disease generally resolves as your child completes their growth, which can take anywhere from a few months to a couple of years. The condition does not affect your child’s overall growth or knee function. The only long-term change may be a small, painless bump below the kneecap, which usually remains as a cosmetic feature but does not cause ongoing problems.
