Im 29 years old and been working as a physio for 5 years.
I myself developed tenderness on my right tibial tuberosity after playing alot of tennis
Usual treatment for this includes getting a knee strap, strengthening the glutues, core, vmo and ankle inversion muscles, getting a orthotic for your shoe and deep friction massage.
I have done all of the above and most effective treatment was deep transverse friction.
It is a very annoying condition and I advise rest from aggravating activities and see a physio …
