Popliteal


Definition - What does Popliteal mean?

Popliteal is a clinical term that relates to the posterior region, or flat surface area, opposite the kneecap. The area serves as the locus of a network of arterial routes and nerve branches that respectively facilitate blood circulation and proprioception (spatial awareness) cues in promoting neuromuscular and sensorimotor functionality. The popliteal fossa comprises the arterial, muscular, nervous, and venous structures contributing to biomechanical health of the knee including the popliteal artery (an offshoot of the femoral artery), distinctive interconnecting leg and thigh muscles (i.e., biceps femoris, gastrocnemius), the fibular and tibial nerves, and the popliteal vein.

WorkplaceTesting explains Popliteal

The knee joint consists of the articulating bones of the tibia and fibula (lower leg) and the corresponding femur (thigh bone) bound together by fibrous connective tissue including cartilage, ligaments, muscles, and tendons, contributing to mobility and stability of the lower extremities. However, the popliteal region is subject to etiological implications from traumatic injuries or strenuous activities that cause gradual erosion of constituent segments of the knee that can limit flexibility and impair range of motion (ROM). Repetitive motions such as bending, sitting, kneeling, and standing can induce physical strain on the knee to the extent that osteoarthritis (OA), rheumatoid arthritis (RA), and meniscus tears can cause chronic pain in the popliteal area of the knee.

Prominent swelling or abnormal growths in the popliteal area are suspect for Bakers’ cyst, or inflammation of the bursa lining the knee joint, and popliteal aneurysms are characterized by a lump manifesting around the site where obstruction of blood flow occurs. Given the taut membrane of fascia tissue covering the popliteal region, pathological growths are likely to compress the tibial nerve resulting in paresthesia (a tingling sensation) and compromise plantar flexion of the foot. Individuals experiencing chronic pain behind the knee should consult a physician to determine if blood clots exist, carrying symptoms that resemble deep venous thrombosis (DVT) if a rupture ensues.

With sedentary positions, employers can introduce ergonomic measures where the postural alignment of the body is compatible with independent workstations tailored for the health and safety of employees. Proper furniture that conforms to the natural curvature of the spine is measurable by placing 2-3 fingers between the edge of a chair and the popliteal region where the spatial distance maximizes the proportionate distribution of the weight of the thighs, offsetting any potential circulation issues of the lower extremity.
