Ideally I would do the knee bending and bracing exercises every day, preferably first thing with the idea of lubricating the joints before using them (and also because what gets done first gets done). I wouldn?t like to do much stretching early in the day, as I fear we are more susceptible to injury then, but this is different. In reality I do it before sessions of weight training and before using the rower or elliptical cross trainer, which adds up to about 4 times a week. It seems to me it is even more important to do it before long walks, but in fact I end up rushing out of the door without. However, I am right now resolving to change all that!
I do believe in the helpfulness of strengthening excises too, but I suppose sometimes nothing can help as much as we want, depending on exactly what?s wrong. However, I?m sure everyone would agree that strengthening, particularly your quads, will be tremendously worthwhile. Even if you were to end up having an op, strong quads would help enormously with recovery. I have a friend of nearly 65 (my age) who had to wait for a NHS double hip op til she couldn?t walk without pain at all, but she carried on riding her bike, weight training and rowing in the gym as much as she could bear. She was out of hospital far faster than the other ?old ladies? on her ward, has made a great recovery and is back rock climbing, though her consultant forbids her to run.
For strengthening my quads I mostly do one leg half squats (or rather quarter squats, because I?m not strong enough yet to go down as far as I?d like). These are good for balance as well, but you can do them holding on too. Half means half way to horizontal thighs. Full squats, as you probably know, are controversial as they put a lot of stress on the knees. It?s important that as you go down you think sitting rather than knee bending, as your knees should never get in front of your toes.
Supplements: I take high dose glucosamine with chondroitine (from Healthspan, mail order), also fish oil (not cod liver oil). There have been some studies suggesting glucosamine is helpful, less for chondroitine, but I?m so keen to do what I can for myself, I think it?s worth taking them. Fish oil is good for you in so many proven ways, one can hardly lose taking it, and I also make sure to eat tinned salmon or sardines 3-4 times a week.
Distance: some years ago my knees got so bad I was truly wondering about a stair lift. For a while I used one trekking pole on walks, and found to my surprise that there seemed to be no correlation between length of walk, rough ground and knee pain. Since then I have joined the LDWA, done events up to 27 miles (don?t really want to walk any further), carried a seriously heavy rucsac along French GRs. HOWEVER since 2005 I have been troubled with an intermittent knee pain which may or may not be arthritic and may or may not bring my walking to an end. Wish me luck!
