Path
     Periods of rapid growth in which the quadriceps tendon puts traction on the apophysis of the tibial tubercle where the patellar tendon inserts.
     The traction is worsened by sports that involve repetitive running, jumping, or kneeling.
     Improves with rest.
     1/4 of affected individuals have bilateral disease.
Hx

     Younger (10-11 yo) affected females
Sx
     Knee pain
PE
     Edema and tenderness over the tibial tubercle
     A firm mass can sometimes be felt due to heterotrophic bone formation
     Pain can be reproduced by extending the knee against resistance
     
Dx
     Radiographic findings are nonspecific and include anterior soft tissue swelling, lifting of the tubercle from the shaft, and irregularity or fragmentation of the tubercle.
