Intervertebral Disc Syndrome (IVDS) can potentially contribute to knee strain, though it does not directly cause it. IVDS primarily affects the spine, where damaged or herniated discs put pressure on spinal nerves, causing pain and neurological symptoms. When IVDS occurs in the lumbar (lower) spine, it can alter a person's gait and posture as they unconsciously adjust to minimize pain. These compensatory movements often place abnormal stress on the knees, potentially leading to knee strain over time. Additionally, if IVDS causes nerve compression that affects lower limb function, it may result in muscle weakness or imbalance around the knee joint, further increasing strain risk. According to a study on the effects of exercise on the intervertebral disc 1, running exercise can strengthen the intervertebral disc, which may help alleviate some of the strain on the knees. However, the relationship between IVDS and knee strain is complex and influenced by various factors, including gait alterations and muscle forces, as shown in a study on knee joint muscle forces and tissue stresses-strains during gait in severe OA versus normal subjects 2. Treatment typically focuses on addressing the primary IVDS through medications like NSAIDs (ibuprofen, naproxen), muscle relaxants (cyclobenzaprine, baclofen), physical therapy, and in severe cases, surgical intervention. For those experiencing both IVDS and knee pain, it's essential to address both conditions simultaneously, as treating only one may not resolve the interconnected symptoms. This connection demonstrates how problems in one area of the musculoskeletal system can create a cascade of effects throughout the body. The most recent and highest quality study on this topic is from 2017 1, which highlights the importance of exercise in maintaining healthy intervertebral discs and potentially reducing the risk of knee strain. In summary, while IVDS does not directly cause knee strain, it can contribute to it through altered gait and posture, nerve compression, and muscle weakness or imbalance around the knee joint.
