“It’s probably just growing pains” is one of the most common things parents hear when their active kid starts complaining about knee pain, and sometimes that’s true. But when the pain shows up specifically below the kneecap, worsens with running and jumping, and sticks around through a soccer or basketball season, Osgood-Schlatter disease treatment is likely what your family actually needs to be looking into. Growing kids’ bodies handle sports injuries differently than adult bodies do, which is exactly why pediatric physiotherapy looks at young athletes through a different lens.
Why Kids’ Bodies Handle Sports Injuries Differently
Children and teenagers have growth plates, areas of developing cartilage near the ends of long bones where new bone growth happens. Until these growth plates fully close in the later teenage years, they’re actually weaker than the surrounding ligaments and tendons, which is the opposite of how things work in a fully mature adult skeleton. This means a young athlete’s body can respond to the same repetitive stress or impact in a very different way than an adult’s would, often showing up as pain right at a growth center rather than in a muscle or ligament. Understanding this distinction is exactly why pediatric physiotherapy exists as its own area of focus.
What Is Osgood-Schlatter Disease?
Osgood-Schlatter disease is one of the most common of these growth-related conditions, and despite the name, it isn’t a disease in the traditional sense. It’s an overuse injury at the growth plate where the patellar tendon attaches to the top of the shinbone, just below the kneecap.
During growth spurts, bones often lengthen faster than the muscles and tendons attached to them can stretch to keep up, and repeated pulling from the quadriceps through the patellar tendon irritates that growth center, leading to pain, swelling, and sometimes a visible bony bump below the kneecap.
Common Symptoms
- Pain and tenderness directly below the kneecap, over the top of the shinbone
- A noticeable bump at that same spot, which can remain even after symptoms resolve
- Pain that worsens with running, jumping, squatting, or kneeling
- Symptoms that flare during and after sports activity and ease somewhat with rest
- Pain that tends to affect one knee more than the other, though both can be involved
Who’s Most at Risk
Osgood-Schlatter disease shows up most often during growth spurts, typically between ages 10 and 15, and tends to affect boys slightly earlier in that range and girls a bit earlier still, in line with typical growth timing differences. It’s especially common in sports that involve a lot of running, jumping, and sudden direction changes, including basketball, soccer, volleyball, and gymnastics, since these activities repeatedly load the patellar tendon right at its attachment point.
Osgood-Schlatter Disease Treatment: What Actually Helps
The encouraging news is that Osgood-Schlatter disease is self-limiting, meaning symptoms generally subside once growth at the tibial tubercle finishes. That doesn’t mean your young athlete has to just push through it, though, since the right approach can meaningfully reduce pain and keep them active in the meantime. It’s also worth knowing upfront that total immobilization or completely stopping sport isn’t necessary or recommended today. The goal is managing load intelligently, not shutting activity down.
- Ice after activity helps reduce pain at the front of the knee.
- Activity modification for 6 to 8 weeks is generally advisable during a flare-up, meaning your young athlete stays active within what their pain allows rather than training at full intensity or stopping entirely. Swimming tends to be well tolerated as a secondary activity during this window, since it avoids the impact that aggravates symptoms.
- Gentle quadriceps and hamstring stretching, paired with strengthening of the vastus medialis oblique specifically, has been shown to reduce pain, since this muscle helps control how the patellar tendon tracks and loads.
- Patellar taping, such as McConnell taping, or a knee brace with an infrapatellar strap can reduce patellar loading and ease discomfort during activity.
Exercise progression matters here more than people often expect. Treatment typically starts with low-intensity, isometric quadriceps exercises performed at multiple angles, since these are well tolerated even during a painful flare.
Higher-intensity quadriceps work and hamstring stretching are then introduced gradually as symptoms allow, and this staged approach has good evidence behind it. Jumping straight into higher-intensity quad exercises too early, before symptoms have settled, can actually intensify pain, which is exactly why the progression matters as much as the exercises themselves.
You may also come across extracorporeal shockwave therapy mentioned as an option for Osgood-Schlatter disease. It’s worth knowing that the evidence supporting it is currently low quality, so it isn’t something we’d confidently recommend over the approach above.
Perhaps most importantly, research comparing treatment approaches has found that combining activity modification with active treatment, like stretching and progressive strengthening, works better than restricting activity alone. Rest by itself isn’t the fix; rest paired with the right exercise program is.
Other Growth Plate Injuries to Watch For
Osgood-Schlatter disease belongs to a broader family of growth-related overuse conditions that show up in active kids and teens. Sever’s disease is a similar condition affecting the growth plate at the back of the heel, common in kids who run and jump frequently, while Sinding-Larsen-Johansson syndrome affects the growth plate at the bottom of the kneecap rather than the shinbone. All of these conditions share a similar underlying cause, repetitive tension on a growth center during a period of rapid bone growth, and respond to a similar overall approach.
When to See a Physiotherapist
Most growth plate discomfort in active kids is manageable and not a cause for alarm, but a few signs are worth a proper assessment rather than a wait-and-see approach: sudden, severe pain, an inability to bear weight, visible swelling or deformity, or pain following a specific fall or collision rather than a gradual buildup. These can point to a more significant growth plate injury, such as a fracture, which needs a different approach than a typical overuse condition like Osgood-Schlatter disease.
Supporting Long-Term Activity in Young Athletes
Beyond treating symptoms in the moment, pediatric physiotherapy also focuses on helping young athletes manage training load as they grow, since rapid growth spurts combined with heavy training volume are a common setup for these overuse conditions. Encouraging variety in sport and movement, rather than early, year-round specialization in a single sport, along with attention to how quickly training volume increases, goes a long way toward keeping young athletes active and pain-free through their growing years.
Keep Your Young Athlete in the Game
Knee pain in an active kid deserves more than a “wait it out” approach, especially when it’s affecting how much they can play. At Richmond Blundell Physiotherapy & Sports Injury Clinic, our team works with young athletes and their families to manage Osgood-Schlatter disease and other growth-related conditions, keeping kids as active as possible while their bodies do the work of growing.
