Degenerative Changes in Lumbar Region Always Lead to Bilateral Degenerative Changes in Knee-Joints and Vice-Versa: Sensation of Pain Cannot Only be The Parameter of Degeneration

Knee joint pain may arise from a disc protrusion in the back. The nerves that transmit the sensation of pain to the legs and feet are located in lower back region. With ageing, discs between the vertebrae bulge out and compressed the nerves, sending pain signals. The locator of pain depends on which disc is protruded. The nerves that send fibres to both the knees are located at the second, third and fourth lumbar vertebral levels in the lower back area. During investigation of patients, we found that if a disc is compressing the nerves on the above locators, the pain is always felt in the knee region. Similarly, we observed in patients that if the pain is in the knee region then there is always degenerative tissue damage in the knee region. In almost all cases compression in the above lumbar vertebral levels take place, even though patients may not feel any pain in the affected regions.
