Can you please describe what you mean when you say "rolls" ? I assumed that you mean you flick over something with your finger? or it is like a little mass or bump in the tissue?
It is likely that following tendonitis you can have residual inflammation which has turned into local scarring within the tendon sheath, if this is what you might mean by "rolls" ? This scarring can be worked out by your local therapist but will likely reduce by doing some low resistance exercise which puts your quads through its ranges. I would suggest a stationary bike with no/very light resistance, put the seat up high to start and do 30minutes peddeling over. This will slide your quads muscle through the tendon sheath, increasing lubrication and hopefully breaking down any scarring. STOP immediately if you feel any discomfort, as this will be the irritation starting the whole injury process over again. Following a few days of this you can try slowly dropping the seat height every 10 minutes from high to low for 30-50 minutes. Again stop if you feel any discomfort.
However, if you mean something else when you say "rolls" let me know and I can try to help. In regards to your Return to Sport... As with most return to sports, you have to start small. i.e. the stat bike as mentioned above, slowly increasing your training intensity (amount/resistance) by no more than 10% per week.
Oh and a quick tipIf you are not a cyclist, try not to do 60hour weeks on a bike with no ramp up training to match. People tend to think of cycling as low impact and easy (comparative to other endurance sports), signing up for quite long rides without appropriate training. You don't see weekend runners suddenly run marathons and not come away with similar conditions for a reason.
Hope some of this helps. Musculoman
