Could an injury/cut near the tendon stimulate the same bony prominence mentioned below
Causes
With repetitive activities, the patellar tendon becomes irritated and inflamed at its point of attachment to the tibial tubercle. This repetitive activity, combined with accelerated growth of a child’s bone, causes traction at the tendinous insertion, stimulating the formation of a bony prominence, which can be seen in the larger “bump” below the knee in the image above.
