15yrs ago I had keyhole surgery to remove cartilage. It’s kind of how I got into cycling as it was my recovery from the op. Fast forward to now and I think I’m going to have to more time off the bike. Hardly been on it due to pain and swelling in the knee. Have an apt with a doctor to see if I can get refered for a scan too see what damage is still there. Right now it’s bloody sore , it occasionally gives way and I’m walking at times with a limp. Shoot me now :-)
