Hi Blakey
It would be good to know what your mechanism of injury was and also what all they repaired during surgery. Did you have Wikipedia reference-linkmeniscus damage as well initially? Did you have surgery to the menisci? s it a click or a locking that you feel in the knee?

Anyway, 2 weeks post-op is still early days, but the sooner the knee gets miobilised the better.
New studies show that the quicker the extension movement is improved the better.
Are you wearing a brace post-op? What are the range of movement settings on it at the moment?

It would help if you can answer some of these questions, but your physio might go through them with you.

Good luck.
