Common Peroneal Nerve Entrapment Decompression Surgery

The peroneal nerve runs along the outer side of the knee and is one of the two major nerves of the leg and foot.

It passes through a fibrous passageway beside the knee known as the fibular tunnel. When this tunnel narrows and compresses the peroneal nerve, it leads to a condition called peroneal nerve entrapment. Dr. Sina Rajamand offers common peroneal nerve entrapment decompression surgery at Saint Mary’s Brain and Spine Surgery near Reno, NV.

The common peroneal nerve controls the muscles responsible for lifting the ankle and straightening the toes. Compression of this nerve can result in symptoms such as:

Pain
Numbness in the foot and/or ankle
Tingling
Weakness in the ankle and foot
Foot drop
Trouble walking

Reno CPN Decompression Surgery

Diabetes, arthritis, or a history of knee trauma can increase the risk of developing peroneal nerve entrapment. In this condition, the common peroneal nerve (CPN) becomes compressed and inflamed. Scar tissue may replace the nerve’s protective myelin sheath, hindering nerve signal transmission to the foot.

When conservative treatments fail to relieve symptoms, Dr. Rajamand may recommend CPN decompression surgery. This minimally-invasive procedure, also known as fibular release, involves making a small incision on the outside of the knee to access the fibular tunnel and relieve pressure on the CPN.

The procedure usually lasts about an hour, and patients typically return home the same day. After a brief recovery, light walking is encouraged, with regular walking achievable within a week. Full activities, including running, should be postponed for four to six weeks. Dr. Rajamand will provide detailed information about the surgery and recovery during your consultation.
