I believe I recall that my orthopod. told me that it kind of scars into the
semimembranosus.   I can't believe that it is very useful afterwards:  no
insertion onto bone any more, and probably kind of gets bunched up anyway.

Functionally,  I never seem to notice flexion problems while
skiing-probably because I don't flex that far.  I don't seem to have quite
the power I used to when I do knee curls at the gym.  I also notice some
problems rock climbing:  my affected side doesn't seem to want to flex to
the acute angles that my unaffected side does when I high-step.  That is
partly due to some loss of range of motion due to chronic stiffness in the
knee joint itself (I had kind of a complicated post-op course: a tiny bony
fragment was left in place after the first operation, and I needed to be
re-scoped;  I also had some cartilage damage on the medial femoral
condyle).  I have always wondered whether the semitendinosus is best for
the last part of knee flexion, and the semimembranosus is best for
initiating flexion.  Does anyone know?
