Knee osteoarthritis (KOA) is a common knee disorder. The pathological changes affecting the knee are typically examined by using X-ray imaging to assess the narrowing of the joint space and the presence of osteophytes. However, some previous clinical trials have revealed a discrepancy between the severity of joint pain and the image finding even with the use of knee MRI. Some studies have revealed that there are age-related changes in the type of fibers with the formation of a network of transverse fiber bands, and this may cause some compression or traction on the neurovascular content of the adductor canal. Other studies noted the presence of excessive yellow-colored adipose tissue that stretches or entangles some nerve fibers. The primary outcome of this study will be the incidence rate of tenderness over the midthigh corresponding to the AC in patients with KOA who are complaining of severe pain that is discordant with the radiological finding.
