Would this be considered an extenuating circumstance for uni?

Hi,
I am wondering if unis would consider this an extenuating circumstance. I am applying to Oxford, Warwick, Bristol, Reading and LSE.
In the same year that I sat my exams. I ahd a surgery at the start of the school term. It was supposed to be a fairly small procedure on my foot after I had severly broken it a few years before. However, there was a complication with the procedure and they had to abort the surgery without fully completing it. I ahdd to undergo a fairly long phase of about 2 months in plater on then with significant swelling. of course I had time of from school during this time. After the surgery, I can walk and run fine but it does have clear moments of discomfort and playing sports for long periods or walkig far can be difficult.
