A child’s swollen knee after injury may happen with a sprain, ligament injury, meniscus injury, or a direct blow to the knee.

Kids knee pain after sports can come from overuse, a twist or sprain, a direct hit, irritation around the kneecap, or an injury inside the joint. The timing of the pain, whether there is swelling, and whether the knee feels unstable can help narrow down the cause.
A child swollen knee after injury can happen with anything from a bruise to a more significant joint injury. Swelling that appears quickly, keeps increasing, or comes with trouble walking, instability, or locking should be evaluated by a medical professional.
A child knee sprain or child knee ligament injury may cause pain after twisting, swelling, difficulty bearing weight, and a feeling that the knee gives out. These symptoms can overlap with other injuries, so persistent or more severe symptoms should be checked by a doctor.
A child knee meniscus injury may cause pain with twisting, swelling, catching, locking, or trouble fully bending the knee. If these symptoms are present, especially after sports or a twist, medical evaluation is a good idea.
Consider seeing a child knee injury doctor if your child cannot walk normally, has significant swelling, hears a pop at the time of injury, has instability, or is not improving over several days. Pain after a fall or direct hit can also need evaluation depending on severity.
