“Altered knee motion is one of the most common gait deviations in pediatric populations with gait disorders. The anatomical and functional aspects of the knee are perhaps why some have described the knee, as a “bad neighbor.” To be clear, the knee can be the source of pain as well as the primary cause of biomechanical dysfunction; however, the contribution or lack of motion at the ankle mortise joint, femoral acetabular joint, and or lumbar subluxations cannot be overstated as primary sources of knee dysfunction. The knee can be thought of as a proverbial “catch 22” for it is literally stuck between a rock (the ground) and a hard place (any potentially subluxated proximal joint)” K. Ernst et al, Examination and specific adjustments of the extremities. Pediatric chiropractic 3rd edition.
“this is your knee.” two weight bearing bones, a non weight bearing bone that acts as a fulcrum to increase mechanical resistance of your quad, and a non weight bearing bone that has little impact on knee function but mostly impacts your ankle movement.
Many insidious knee problems (that came on without cause) are actually the result of dysfunction above the knee:
dysfunctional hip mobility placing uneven load transference at the joint, muscle tightness causing excess tension loading or poor neurological control from the lumbar spine causing poor mechanics at the knee joint,
Or from below the knee: poor ankle mobility causing excess mobility at the knee to accommodate, or weak foot shock absorption causing excess gravitational stresses to the knee joint.
Traumatic knee injuries almost always result it instability due to the necessary soft tissue support of the joint. And once the joint has healed from the trauma, there’s often significant fear of reoccurrence. This can cause significant muscle guarding that can persist even after the original injury heals, often resulting in pain and dysfunction.
Essentially, if you have a knee injury, you need to make sure you are working on your ankle, hip and low back as well as the knee.
