I would check his SLR and assess how he runs. Has he had a sudden growth spurt recently or does he sit slumped at a computer all day? From my experience patients blame thier sport but its usually what they do for the majority of the time that gives them the problem.ie sitting, standing


This does not sound like a primary knee problem and the referred pain is probably referred somatic pain from his spine (and hence no change in dermatomes.myotomes).
I am not a big fan of trigger points and think these are an indication of a problem elsewhere.
