I'm torn a ligament in my knee so am having an op as neither physio nor time have been able to sort it out. I'd assumed op would be done under local but it's a general. It's at least 10 years since I've had one so am expecting effects to be greater than last time. Of course they may not be, but there is there anything I can do to minimise after effects of anaesthetic and op. (Am continuing to do leg exercises to build up muscles to help on that front). TIA.
