Hi Ophqui,
I know of one lady ( in her fiftees) who had Osgood Slatters as a child and has had problems with her knee on and off since. Her tibial tuberosities is larger and it can play up.
I know that applying elastic therapeutic tape (kinesio, kinesiology,curetape,easytape etc etc) can really help relieve the pain in adolescents and she has found out that it works for her as well. My tape of choice is CureTape.
