TKR 3 years ago, chronic pain and stiffness in 69F. “Rule out partial Quadriceps tear” MRI. Please Help

Referral asked “r/o partial quad tendon tear”; maybe it’s scarred, but is
not torn. There is a low lying patella. I see this dark signal thickening
posterior to the patella which contacts the deep surface of the patella and
seems to extend to the anterior tibial margin…though it seems separate
from the patella in the Ax plane.

Is this the normal pseudocapsule post TKR?
Is there excessive scarring possibly tethering?
I really don’t know…please help.
