> Hi,
> I had patella reconstruction on my left knee 5 weeks ago.
> Fell on the stairs yesterday when my right leg slipped,

> or two in a 90 degree bent position then I fell over.
> Since then I can walk on it but it is more swollen and
> there is pain when I bend it (the rehab had been going well
> and there had been no pain recently).
> How do I know if I have done further damage? Is putting all

> I am due for a check up with an x-ray in a week, but wonder

> Yours anxiously
