What is Osgood-Schlatter disease

It is irritation of the growth area at the tibial tuberosity — the spot just below the kneecap where the patellar tendon attaches. During a growth spurt the bone grows faster than the attachment strengthens, and frequent jumping and running pull on it through the tendon.

It most often affects boys aged 12–15 and girls aged 10–13 who play football, basketball, volleyball or do gymnastics. It can affect one or both knees and almost always settles when the growth plate closes.

Symptoms

Pain below the kneecap when running, jumping, squatting and kneeling.
A tender swelling or bump on the tibial tuberosity.
Pain is worse after training and eases at rest.
Sometimes both knees hurt.

Diagnosis

An examination is usually enough: the doctor finds the tender spot below the kneecap and the link between pain and activity. X-ray or ultrasound is done if the picture is atypical — to rule out a fracture, infection or tumour. Similar symptoms occur with patellofemoral pain and patellar tendinopathy.

Osgood-Schlatter disease: treatment options

The treatment plan is made by the clinic doctor after an examination and a review of your images. The table shows the options usually discussed for this diagnosis and how well they have been studied.

Option	What to expect	How well studied
Load management, weight loss	Takes load off the affected area; if overweight, losing 5–10% noticeably reduces pain	Moderate evidence
Exercise therapy and physiotherapy	Reduces pain, strengthens muscles, improves function; the basis of treatment	Moderate evidence
Ice, patellar strap	Reduce pain after activity	Little data
Painkillers and NSAIDs	Ease pain during flare-ups; long-term use is limited by side effects	Limited or conflicting evidence
Corticosteroid injection	—	Not usually used for this diagnosis
PRP / CGF	—	Not usually used for this diagnosis
Removal of a bone fragment	Rarely: in adults whose pain persists after growth has finished	When indicated — the doctor decides

We send your request to several partner clinics. Some will suggest conservative treatment or injections, others surgery; each clinic quotes its own conditions and price. We help you compare the options.

Is surgery needed

Children and teenagers almost never need surgery. Steroid injections are not given in this area. Surgical removal of a bone fragment is rarely discussed — in adults whose pain persists after growth has finished.

Duration and sport

Stopping sport completely is usually not necessary. Load is reduced for a while — fewer jumps and sprints — and adjusted to pain, while the thigh and knee muscles are strengthened. In a study, most teenagers on such a programme were able to return to sport. Symptoms usually settle within 12–24 months; the bump below the knee may remain, but it is not dangerous.

What to prepare for a free review

Images: MRI, ultrasound or X-ray (DICOM files or photos of the screen) and their reports.
When and how the pain started, where exactly it hurts, what makes it worse or better.
Treatment so far: injections, physiotherapy, surgery — and how it helped.
Other conditions and medications, especially blood thinners.

With this information, a partner-clinic physician can say whether further tests are needed and which treatment options suit you.

When to see a doctor urgently

Pain at night and at rest, unrelated to activity.
Fever, redness or swelling of the whole knee.
Unable to put weight on the leg after a jump or fall.

Contraindications to injection treatment: active infection, active cancer, clotting disorders, pregnancy. Possible risks of injections are a temporary pain flare and swelling for 1–3 days and, rarely, infection; the treatment may also not work.

Frequently asked questions about Osgood-Schlatter disease

Can my child keep playing sport?

Usually yes, but with less load: fewer jumps and sprints, training guided by pain. Complete rest is not needed and does not speed up recovery.

How long does Osgood-Schlatter disease last?

Usually 12–24 months, and it settles when the growth plate closes. Pain may come and go during this time.

Will the bump below the knee remain?

Sometimes. It is not dangerous in itself; if it hurts in an adult, removal of the bone fragment is discussed.

Will injections help?

Steroid injections are not used for Osgood-Schlatter disease. PRP and cell-based methods are not used in teenagers.

How can RegenPAS help?

RegenPAS is a patient service centre in Munich, not a clinic. We review your images and symptoms and send a request to several partner clinics at once. Clinics that can accept you send their own conditions and price; prices differ between clinics, and you choose the option that suits you. The coordinator replies within 24 hours, and a clinic physician’s preliminary opinion follows in 1–3 business days. We then arrange the appointment, visa invitation, interpreter, transfers and accommodation. Treatment decisions are made by the clinic physician. Contact a coordinator.
