Knee and ankle pain: While sometimes there is an internal cartilage problem untreatable by anything less than surgery, this sensation often responds to the alignment of the bones of the spine as well as the leg.  Because the enervation to the leg originates in the low back, a lumbar adjustment alone can sometimes resolve this difficulty.   Another important factor to consider is the possible need for an orthotic.  If the patient pronates due to a history of ankle or foot problems, a Sole Supports orthotic may be indicated.
