Peroneal Nerve

Peroneal Nerve

There are various complications that can arise from high tibial osteotomies (HTO).  Neurologic injuries such as damage to the peroneal nerve are one of those complications.  HTO’s are often performed to relieve the pain associated with knee osteoarthritis.

The peroneal nerve lies between the biceps femoris tendon and the outside top portion of the calf muscle, and winds around the top of the fibula bone.  The peroneal nerve branches out to various other nerves in the lower leg.  Nerves are like cables that provide pathways for the electrochecmical impulses that drive the central nervous system.

Damage to the peroneal nerve can result in drop foot, making the foot drag during walking.  Also feeling can be lost in the top of the foot and front of the lower leg.

Popliteal Artery

Popliteal Artery

A common surgery to treat osteoarthritis of the knee is a high tibial osteotomy.  Complications during the surgery can include neurologic injuries.  One such injury is damage to the popliteal artery.

The popliteal artery is an extension of the femoral artery, located behind the knee.  It supplies blood to the knee joint and muscles in the thigh and calf. Arteries are blood vessels that bring oxygen rich blood from the heart to various tissues in the body.

Damage to the popliteal artery can cause a partial or complete blockage of blood flow to the foot and lower leg.  This can cause pain, difficulty walking, or amputation.
