The knee is a powerful and complex joint. Indeed, our knees are used when we walk, run, jump, etc. These actions require the flexion of the knee and the activation of the muscles found within this joint. The knees also play an important role in stabilizing our posture. As they are frequently called upon and support the weight of our body when we stand and move around, knee pain is common and afflicts many people.
In Canada, 1 in 6 people suffer from some form of osteoarthritis, and although symptoms most often appear between the ages of 40 and 50, they can occur earlier. In general, women 55 and older are more affected, and most people over the age of 70 are living with this disease. Unlike inflammatory arthritis, whose pain is often nocturnal and is more or less continuous, osteoarthritis is felt more during the day, and pain increases with exertion as the joints are used.
