Why Young Athletes Experience Knee Pain During Growth Spurts

If your child has come home from practice limping or complaining about achy knees, you are not alone. Knee pain during growth spurts is one of the most common concerns parents of young athletes bring to pediatric physical therapists, and it makes complete sense why it would be worrying. Your child loves their sport, they are working hard, and suddenly their body seems to be working against them. The good news is that this kind of pain is well understood, very treatable, and does not have to sideline your young athlete for long.

What Is Actually Happening Inside a Growing Body

During a growth spurt, the long bones in a child’s legs, particularly the femur and tibia, can grow faster than the surrounding muscles and tendons can keep up with. This rapid change in bone length creates tension in the soft tissues that attach to those bones. Around the knee, this tension is especially noticeable because of how much force the quadriceps muscles place on the front of the lower leg during running, jumping, and squatting.

The result is often inflammation and discomfort at the point where the patellar tendon attaches to the tibia, just below the kneecap. This condition is commonly known as Osgood-Schlatter disease, though calling it a disease can feel alarming when it is really a very normal response to a body that is growing quickly. Other young athletes may experience a similar issue behind the kneecap, known as Sinding-Larsen-Johansson syndrome, which involves the attachment point at the bottom of the kneecap itself.

Why Active Kids Are More Vulnerable

Young athletes who are in the middle of a growth spurt and continuing to train at high intensity are placing repeated stress on tissues that are already under strain. Sports that involve a lot of running, jumping, or quick changes in direction, such as basketball, soccer, gymnastics, and volleyball, tend to increase the likelihood of these symptoms developing. This does not mean your child needs to quit their sport. It means their body is asking for some thoughtful support and attention.

Muscle tightness in the hamstrings and quadriceps is another contributing factor. When these muscles are tight, they pull more forcefully on the knee structures during activity. Strength imbalances around the hip and core can also shift how load is distributed through the knee, making certain areas more vulnerable to irritation.

What Families Can Do at Home

While professional guidance is always the most effective path forward, there are some supportive steps families can take in the meantime. Encouraging your child to warm up thoroughly before practice and cool down with gentle stretching afterward can make a meaningful difference. Applying ice to the sore area after activity for short intervals can help manage inflammation and discomfort. Paying attention to how much your child is training and building in adequate rest days is also important, since overtraining during a growth spurt significantly increases the risk of ongoing pain.

Open communication matters too. Encourage your child to tell you honestly how their knees are feeling rather than pushing through pain silently. Pain is information, and listening to it early leads to much better outcomes.
