3 week hx of knee pain

[Una]

Hi,
I came home from training a three weeks ago and suddenly found extension of my knee painful on the posterior aspect of my knee (no history of injury in the training session). It was also sore in the extremes of flexion - like squatting and flexion with medial rotation. The pain has always been medial and posterior without any swelling and there isn't any tenderness along the joint line.
I was training last night and it seems to constantly catch on turns - it just hurts for a few seconds now - like a pinch. There's a little discomfort in hyperextension but I have been able to train and play with a bit of niggling discomfort.
With the fact its there now for 3 weeks I was wondering should I seek some advice. My teammate who's a physio glanced at it quickly and all the screening tests were negative but semimembranosus was tight near its insertion. I was wondering can lower tears present with this and should I bother seeking proper physio advice in case its something more sinster. And is the posterior pain due to the oblique popliteal ligament.
I think this the paranoid med student syndrome - i've been around too many knee injuries all year!
Thanks a million

Hi,

Definitely get it checked out by a physio for a full assessment.

Make sure that they do the meniscal tests at all angles of flexion/extension and using lateral and medial rotation as it does sound like perhaps there is a small nick in the cartilage which is only presenting in certain degrees of flexion/extension. This could present as posterior knee pain depending on where the defect in the cartilage is, of course!

Good luck and let us know how you get on!
