I’ve had fairly bad knees for a long time – cartilage damage from too much football (soccer) when I was young.
A long time ago when I was still playing, a couple of days after a match, I went to my doctor with an extremely swollen and painful knee. He told me to quit football, there was nothing that could be done. My club sent me to a sports physio. When I told her what the doctor said, she said “NONSENSE” (a different word really, but unprintable).
Over a few visits she treated the swelling/inflammation and got that down, but the main thing was she put me on the exercises to further strengthen my quadriceps. She explained that keeping these muscles very strong served to keep the bones apart – rather important on impact whilst running etc. especially with cartilage damage.
Six weeks later I was playing football again and continued for many years until the knees really could take no more. I pretty much gave up all forms of exercise.
Many years later I had put on too much weight and the bits of exercise I was doing then had no effect. So, I decided that I would try some running to see if that would help. My knees were always stiff and sore then, so, remembering my old physio, I strengthened up my quads again and started very gently jogging 2 or 3 times a week for a few minutes.
The knees were fairly ok with this – I think because just running is a straight line activity, whereas all the swerving and changes of direction entailed in playing football were what stopped me before.
A few years on and I am still running. Yes, I do get some knee pain, but it is manageable.
The exercises I did originally entailed sitting on a high bench, chair, desk or something, with a weight on my dangling foot (these days you could use ankle weights or some machine if you choose), then doing 2 sets of around 20 reps of raising the lower leg until the leg was straight. I did this twice a day.
These days I am just careful to more gently exercise the quads every couple of days or so.
If you have knee problems while exercising, please note that everything in this blog is my personal observation of my own condition. I’m not a doctor or health professional of any sort, so please DO see your doctor, but even more importantly, a qualified sports physio.
Having got that out of the way, here are my observations about my experience.
I find that for me, fast walking seems to do more damage than running. I know that the impact is higher when running but I think that the walking action – where the leg is straighter on impact – has a more detrimental effect in my case. Also, I know that many experts say that running on softer surfaces are better, but I find that if they are uneven (and they often are!) they are worse.
I am very careful of the exercises that I select to strengthen the quads. I suggest that things like squats or lunges are out – anything that bends your legs under stress at more than a 90 degree angle. And avoid stretching of muscles/ligaments etc with a straight leg too.
So, to sum up
a) See a sports physio.
b) Strengthen your quads and keep up with the exercises even after you have started running/walking again
c) Be careful about bending your legs too far under stress. And be careful about stretching with straight legs
d) Avoid fast walking or running on uneven surfaces
