Enlarged tibial tuberosity causing inflammation of the patellar tendon at the location where the patellar tendon inserts into the tibial tubercle. Common in young, male athletes.
During growth spurts in young athletes, the quadriceps muscle, which is much stronger than the patellar tendon, can pull away the patellar tendon from the tibia, causing pain.
Pain and/or tenderness just below the kneecap at the patellar tendon insertion on the tibial tubernacle.
