Just before Easter 2012, my knee gave way and now walking has come to an end. Off to see (no doubt pricy) private consultant on 8th June to see what can be done.
Thankfully I have discovered that cycling has no apparent affect to my knee and certainly no pain. I will also see if canoeing without kneeling is suitable. I always tend to kneel.
Anyway cycle stuff can be found at http://randombikerides.blogspot.co.uk/
