Osgood-Schlatter Disease (Growth-Related Knee Pain)
Written by Dr Joshua Hatch, Musculoskeletal GP, RACGP Fellow, Diploma in Musculoskeletal Medicine (FSEM UK).
Osgood-Schlatter disease occurs where the patellar tendon attaches to the top of the shin bone. In a growing child this attachment includes a growth area that is weaker than mature bone, and repeated pulling from the thigh muscles during running, jumping and kicking irritates it. It is common in active adolescents, more so in boys, and one knee or both can be affected. Sinding-Larsen-Johansson disease is the same process at the lower edge of the kneecap and is managed in the same way.
Assessment focuses on the history, the location of tenderness and ruling out features that do not fit, such as night pain, fever, a hot swollen knee or a recent injury. The diagnosis is made clinically. Imaging is needed only when the picture is uncertain or atypical.
First-line care is reassurance, adjusting the amount of jumping, running and kicking to what the knee tolerates, and strengthening and gentle stretching of the legs. Ice or simple pain relief can be used for flare-ups. The evidence behind these measures is limited and practice varies, so outcomes cannot be guaranteed. Procedures such as injections or shockwave are not part of care for children and adolescents with this condition. See your GP if knee pain is limiting sport or school, or if symptoms have lasted more than a year or two.
This page is general information, not a substitute for individual medical advice.
Common symptoms
- Pain and a tender bump just below the kneecap
- Pain during or after running, jumping or kicking
- Pain when kneeling
- One or both knees affected, sometimes with a limp after sport

Evidence for twelve treatment options in osgood-schlatter disease (growth-related knee pain)
This is not a fixed ladder or a package of treatments. Every option is assessed independently against this diagnosis, including treatments with limited direct research that may still be reasonable for a clearly defined tissue target. The evidence level, likely benefit, risks, cost and alternatives are weighed at consultation.
Foundation: diagnosis, education and rehabilitation
The part of care with the broadest relevance. For many people it is enough on its own; other options are judged against it, not automatically added after it.
Diagnosis, education and progressive rehabilitation Working out what is driving the pain, explaining what your imaging does and does not mean, and building a graded loading plan you can actually follow. The treatment
What it involves
Assessment to identify the likely pain source, an explanation of what the diagnosis means, adjustment of the loads that aggravate it, and a progressive strength and conditioning plan, with weight management where that is clinically relevant.
What the evidence shows
No trial has compared specific exercise with sham or usual care for Osgood-Schlatter disease (Corbi, Healthcare 2022), and practice among specialists is highly variable (Lyng, Scand J Med Sci Sports 2020). The Perth Children's Hospital guideline advises reassurance, limiting jumping, running and kicking until pain settles, simple quadriceps stretching, and advises against immobilising the knee. The Royal Children's Hospital adds strengthening and gentle stretching of the lower-limb muscles, with taping or a sleeve for sport.

Where it fits
The mainstay of care is activity adjustment with graded leg strengthening and gentle stretching, alongside reassurance. The evidence is limited, outcomes vary, and benefit cannot be guaranteed.
Muscle and symptom-modifying options
Useful only when the examination identifies the tissue they target or when short-term pain control creates a useful rehabilitation window.
Wet needling and trigger point injection (trigger point injection) A fine needle into a tender band of muscle, with a small volume of dilute glucose solution injected through it. Not offered to children
What it involves
The needle is placed into the tender muscle band and a small volume of 5% glucose with a very dilute local anaesthetic (0.02-0.08%) is injected. Often done in the same visit as your assessment, and usable where the tender area sits deeper. Dry needling (the same technique with nothing injected) is not offered here.
What the evidence shows
Osgood-Schlatter disease is a self-limiting growth-related condition of children and adolescents. The Perth Children's Hospital guideline and the Royal Children's Hospital sheet recommend reassurance, activity modification, stretching and strengthening, with no role for procedures. A 2022 review reports only low-quality evidence for saline and dextrose injections, discourages corticosteroid injection because of tendon risk, and describes surgery as a last resort after skeletal maturity (Corbi, Healthcare 2022). The clinic does not market procedures to adolescents for self-limiting conditions.
Pairing reviewed 2026-11-07.
Where it fits
Not offered. Care is reassurance, activity adjustment, and strengthening and stretching, with review if symptoms last beyond about 18 months.
Ultrasound-guided injections Guidance means the needle can be seen reaching the target. What goes into the needle depends on the diagnosis. Not offered to children
What it involves
The injection is performed under ultrasound so the needle can be watched into the target structure. What is injected is decided by the diagnosis, and corticosteroid is used sparingly, for the reasons set out below.

V-ACTOR vibration therapy (vibration therapy) Low-frequency vibration applied over tender muscle. Not a shockwave, despite sharing the machine. Not offered to children
What it involves
A vibration handpiece is moved over the tender muscle and fascia for a few minutes. It runs from the same STORZ MASTERPULS icon console as radial shockwave but is a separate handpiece delivering a different, gentler form of energy. No needles, no anaesthetic, no downtime.

Energy-based treatment options
Radial pressure wave, focused shockwave and EMTT have different targets and different evidence. They are assessed separately rather than treated as one category.
Radial or focused shockwave? Read the overviewRadial shockwave (radial pressure wave) Broad treatment across tender muscle and fascia, close to the surface. Not offered to children
What it involves
A handpiece is moved over the tender tissue while ballistic pressure pulses are delivered, using a transmitter head chosen for the tissue, including heads shaped for fascia and for the muscle either side of the spine. The pulse is strongest at the skin and weakens with depth, so this is mainly a myofascial treatment, though it can reach deeper in some areas. No anaesthetic, no downtime, usually a course of sessions about a week apart.

Focused shockwave (ESWT) A true shock wave converging at depth: for tendon, joint, ligament and bone. Not offered to children
What it involves
A focused system generates an acoustic shock wave that converges at a focal point set at a defined depth, concentrating the energy where the target is. This is the form used for tendon, joint, ligament and bone. Typically four to six sessions about a week apart, no anaesthetic and no formal downtime.

EMTT (magnetotransduction therapy) High-energy magnetic pulses applied over the area. Usually painless, no contact. Not offered to children
What it involves
You sit with the applicator positioned over the area for a short session. It is usually painless and needs no gel or skin contact. It is usually given as a course, commonly alongside shockwave.

This is general information only and suitability is assessed individually. Treatments with limited or condition-dependent evidence may still be discussed, but only with clear explanation of the uncertainty, the expected benefit, risks, cost and alternatives. Red flags, progressive neurological symptoms or suspected serious pathology require a different pathway.
Every treatment above is described in full on the non-surgical treatments page, including what each one is used for and what the evidence supports. Ratings apply to the named diagnosis; an adjacent muscle, tendon, joint or nerve problem is assessed as a separate target. The method behind the ratings, and the treatments not offered, are set out on the evidence page.
Corticosteroid injection is reviewed separately for each diagnosis.
Cortisone reliably reduces pain in the short term, and that can be genuinely useful when pain is stopping you sleeping or moving enough to rehabilitate. Beyond that window the picture changes. A systematic review of 41 randomised trials and 2,672 participants found that corticosteroid injection reduced pain in the short term but that the effect reversed at intermediate and long term; in pooled analysis for lateral epicondylalgia the short-term effect was large (SMD 1.44, 95% CI 1.17 to 1.71) while no intervention was favoured at 26 weeks (-0.40, -0.67 to -0.14) and at 52 weeks (-0.31, -0.61 to -0.01) (Coombes, Lancet 2010). In a randomised trial in lateral epicondylalgia, 83 per cent of the corticosteroid group had completely recovered or much improved at one year against 96 per cent given a placebo injection, and recurrence ran at 54 per cent against 12 per cent; adding physiotherapy made no significant difference at one year (Coombes, JAMA 2013). In joints, repeated corticosteroid injections have been associated with cartilage loss. It does not repair anything.
So treatment plans are not built around it. Where an injection is the right call, the specific diagnosis and target are reviewed, what is being injected and why is discussed, the number is kept low, and it is paired with the loading work that changes the longer-term course.
When it might still be considered
- Pain severe enough to block rehabilitation
- A clear inflammatory or bursal target on imaging
- A specific short-term goal: a trip, a procedure, a return to work
- Diagnostic use, where the response shows where the pain is coming from

Other knee conditions
Pain in the same area can come from more than one source, and the label matters less than what the examination and history point to. These are the other guides for this region.
