About this trial
The main symptom of knee osteoarthritis, which occurs after damage to the joint cartilage with age, is pain, but this symptom often becomes chronic. Current conservative treatments have moderate effects on chronic knee pain and their use is limited due to the risk of side effects. In addition to pain, patients also experience other symptoms.
As a result of the osteoarthritis process, prorioception in the knee is impaired with a decrease in mechanoreceptors, resulting in loss of balance and an increase in the risk of falling.
