of the patellar ligament, right at the point where it inserts on the tibial tuberosity,
resulting in painful swelling just below the knee. It’s named after two orthopedic surgeons;
the American Robert Osgood, and the Swiss Carl Schlatter. So focusing in on the knee, the proximal epiphysis
of the tibia, which is the upper end of the tibia that contributes to the knee joint,
has a bony prominence called the tibial tuberosity. This is considered an apophysis, meaning that
it’s a bony prominence that serves as a site for tendon attachment. The tibial tuberosity specifically serves
as the attachment site for the patellar ligament, which is an extension of the quadriceps muscle
tendon. When the patellar ligament contracts, it extends
the knee. At birth, the proximal epiphysis consists
of cartilage, but it contains an ossification center inside. This ossification center begins to ossify
or turn to bone between the age of nine and fifteen, and becomes a bony tuberosity around
the age of eighteen. Osgood-Schlatter disease typically develops
between the age of nine and fifteen when the tuberosity hasn’t ossified yet, and therefore
isn’t hard enough to resist traction of the patellar ligament. So, this is why the disease is very common
in young adolescents who play sports requiring the quadriceps muscles to contract repetitively,
causing the patellar ligament to excessively strain on the not-yet-ossified tibial tuberosity. This results in inflammation of the ligament
at the point it inserts to the tuberosity, what is known as traction apophysitis. When the traction is too excessive, it can
cause the ossification center inside the tuberosity to crack into tiny bone fragments. Eventually, that results in a more prominent
tuberosity or a callus, during the healing process. Fortunately, Osgood-Schlatter disease resolves
itself as the ossification of the tuberosity continues as a child grows .
Symptoms of Osgood-Schlatter disease are a palpable lump below the knee, which gets very
painful with physical activities like running, jumping, squatting, and especially when going
up or down stairs, or when the knee gets hit by something. The diagnosis of Osgood-Schlatter disease,
is mainly based on inflammation of the tibial tuberosity, which worsens with activity. In addition, an ultrasound can show soft tissue
swelling around the tuberosity and an X-ray might show fragmentation of the tibial tuberosity
in severe cases. The treatment of Osgood-Schlatter disease
mainly consists of reducing physical activity, and applying ice to the tuberosity to reduce
swelling, as well as pain medication. However, surgery might be necessary for persisting
pain, especially if fragmented bones have avulsed off, and get trapped within the patella
ligament. Alright, as a quick recap, Osgood-Schlatter
disease results from repetitive traction of the patella ligament on the tibial tuberosity,
causing it to become inflamed, which results in a painful swelling just under the knee. This disease typically affects young adolescents
who are active in sports, and its treatment consists of reducing the physical activity,
pain management, and waiting for it to heal as the child grows up. Occasionally, surgery is needed.


  1. I'm 18 and it's been around 4-5 years now that I'm suffering from osgood-schlatter disease. Will it ever recover????

  2. In the first minute of the video I found some errors… be carefull of the terms you use. The rest of the video was fine. I really like your videos, but I didn't like to ear those errors.
    The worst was ''when the patellar ligament contracts'' at 1:05, ligaments don't contract, only tendons and muscles contract. Attention to that please.

  3. I had it and it hurt like hell it stopped hurting and I was chasing this kid at school and it hurt again I went to the nurse got ice and it doesn’t hurt no more I’m scared to do physical activity now

  4. Man i had this on one knee, then the other. IT SUCKED. It hurt so bad lol. I remember the first weeks, or whenever I exercised, just touching it would hurt. Glad its over. Even tho i have the lumps on both my knees to show for it.

  5. What i do is that i use elastic bandages to protect it and it even doesn’t hurt when i do exercise, i’ve had this since i was 13 now im 15

  6. My son has Osgood schlatter diagnosed at age 12….his doctor said osgood schlatter is more of a nutritional deficiency his body didn't absorb nutrients for connective tissue development….he had to get off all gluten and dairy. Eat a lot of chicken/fish….he shot up a foot in height and the pain went away for a couple years then came back due to a poor diet again…he's on a even stricter diet and taking supplements to help clear out his intestines….hopefully it works again because its been a long time since he grew again.

  7. I've had Osgood Schlatters disease in both of my knees since I was 11 or 12. At the time of diagnosis I was told that it should go away in a year or two. I am now 19 and it still persists. I'm pretty damn sure I'm gonna have it forever, and will probably have to get knee surgeries when I'm older..hehe so fun love that lol lmao rofl

  8. I'm 15 going on 16 female and thought I was done growing in height but I have this in both knees, does it mean I'm still growing even though I'm a dancer which would cause strain on my knees?

  9. I have it too and accidentally hit it against my table while watching this video… I literally wanna cry rn..

  10. This is the answer you are all looking for

    This problem can come back while your child is still growing, but it should stop when your child's growth spurt ends. Osgood-Schlatter disease may leave a painless bump on the bone that remains after the problem has gone away.

  11. I was diagnosed at 13, now I'm 31 and the pain is horrible. I just started working out pretty hard core. I wear stretchy brace and it helps a bunch. But when u dont wear it the pains sucks. Prepare for a lot to have it most your lives.

  12. As an overactive youth who played every sport available, this terrorized me for years… I'm really happy this is something you grow out of, however the oversized lumps still remain and make it difficult to kneel. (Still kills if you bump it)

  13. I am watching this video while studying for orthopedic final exam, i am a fifth year medical student.THANK YOU so much

  14. I am 26 and suffer from this still. There has never been enough information on it. Why should we suffer our whole lives with no answers. Decriminalize cannabis and let us live and work pain free.

  15. Growing up just touching it would hurt and if I hit it on a table or had to kneel on a hard surface there was extreme pain. Sadly for me it didn't just "resolve" itself and continues to be sensitive and soar, though luckily not to the extreme as a youth. I still can't kneel on it and after sports or others activities it can get tender, and enough so that bumping it hurts but thankfully it's not blinding pain. The bump itself looks slightly different than others I've seen; it's not round at all but more like a ridge or a blunted shark fin that comes to an elbow-like top. Still a pain in the butt(or leg) even in my mid-30s.

  16. Does everyone has that disease here because it hurts. I hit my knee on the edge of a table the other day

  17. I have osgood schaltter disease and i had it since 9 and im now 13 YO.(ps. I play soccer).For me it even hurts when im not doing anything soo i am prepearing for surgery at 29th october hope it goes well. And i have epilepsy too.


  19. Got this when I was 12 and I am not even lying but you might think I am I could not even walk up my stairs for a day until I slept and woke up it hurts alot.

  20. I’m a hard core dancer and I can’t even do a Grand Plié or kneel down. (btw if you don’t think it’s a sport take an actual intermediate ballet class and then you can give me your opinion.)

  21. i am 22 years old i got this disease in my early 20s. it hurts
    Form 8th grade i used to play but never suffered fro this problem but why now
