Hi guyz, a friend of mine wrote me this:

“echo diagnosis: small
retro-patellar bursitis left which seems to confirm the presence of a
true tendonitis, highlighted by a small fluid blade located at the purse
retro-patellar.
The pain is similar to a strong pressure point below the knee.
It appears on all movements of squat (from 75% of the motion until the
parallel).
In a full squat position, the pain seems to subside.
In a squat position where the hamstrings are parallel to the ground, the
pain subsides when I rock my body weight forward and increases when I
rock the weight back.
During the raising phase, and on the pulses, the pain is also present.
On the ground, If I contract the quadricep, outstretched leg, and that I
make an effort to push the leg upwards while applying a reverse
pressure on the leg, strangely to, I have no pain.
Despite a break of several months, two osteopathy session, three
mesotherapy session, the problem persists and i have no idea of the
exact origin or method to use to solve this problem.”

i don’t know how to help him if you have any ideas it would be greatly appreciated
