Do you still think it is a problem of worn cartilage or degeneration?
90% of knee pain is caused by twisting the knee!
The pain in the knee is not only because the cartilage in the knee is worn out, but the soft tissues like joint, tendon and the joint sac that surrounds the knee are often torn or overloaded. The pain can explain that the pain continues even after surgery or taking medications. What causes pain in the ones surrounding the knee? The twisting of the foot which is supporting the knee from below and the twisting of the pelvis, which is adjusting from above the knee, causes the leg to twist. This causes knee torsion as the feet and pelvis are distorted, and due to the twist of the knee, ligaments, tendons, and muscles react sensitively to small irritations, resulting in knee pain.
