When our feet buckle or twist as we move or stand, the knee has to compensate and try and absorb the uneven forces that result. Often, they are greatly assisted in this job by the powerful muscles around the pelvis which support the weight of our body when one foot is off the ground as we walk or run. But if these muscles aren’t strong enough or aren’t working properly, then the load falls largely on our knees.
And here’s where things start to go wrong. Imagine a door with a heavy weight attached to one corner. This weight would cause the door to bend and twist. Pressure would build up on the hinges of the door which can only move in one direction – open and shut, open and shut. This is what happens with your knees. Shearing forces build up on tissues which are not designed to take them over prolonged periods. Pain and stiffness result.
A lot can be done to correct this if the problem is dealt with before significant damage is done to the knee joint. If you’re experiencing persistent knee pain don’t assume that this an inevitable sign of ageing. Have it checked out by someone who will look at how the balance of forces from above and below the joint is working.
