Dr. Garcia presents his surgical technique for treating an uncommon diagnosis of peroneal nerve impingement.

In this video, Dr. Grant H. Garcia demonstrates his specialized surgical technique for a Peroneal Nerve Decompression.

The patient is a young, active male who had previously undergone a lateral meniscus repair by an outside surgeon. Following that initial surgery, he developed severe peroneal nerve symptoms—such as burning pain, numbness, or foot drop—confirmed by an abnormal electromyogram (EMG) and a positive Tinel's sign (tingling elicited by tapping over the nerve). The goal of this surgery is to release the tight anatomical structures compressing the nerve to restore its normal function.

Surgical Process Breakdown

• Utilizing and Extending the Old Incion: Dr. Garcia accesses the surgical site by using the patient's pre-existing scar from the previous lateral meniscus repair. He extends this incision slightly more upward (proximally) to gain wider access to the native nerve pathway.
• Locating the Nerve via Key Anatomical Landmarks: The surgeon intentionally begins his dissection in the upper portion of the surgical field, where the anatomy is unscarred and easiest to navigate. He uses the direct and indirect heads of the biceps femoris muscle as his primary structural roadmap. Dissecting carefully along the lateral side of the knee near this muscle, he successfully isolates the main body of the common peroneal nerve.
• Identifying the Site of Compression: Once the nerve is safely exposed, Dr. Garcia traces its path down toward the head of the fibula bone. He notes visible physical discoloration in the nerve tissue, which serves as a direct clinical indicator of where the chronic compression and lack of blood flow were occurring.
• Releasing the Fascial Bands: As the peroneal nerve wraps tightly around the neck of the fibula, it passes through a narrow muscular tunnel. The surgeon meticulously releases the overlying superficial fascia of the peroneal muscles, as well as the tight fibrous bands running over the extensor hallucis longus (EHL) and tibialis anterior muscle compartments. He cuts away multiple restrictive fibrous bands to give the nerve completely free, unhindered mobility.
• Inspecting the Nerve Branches: To minimize bleeding and maximize safety, Dr. Garcia stays strictly within the fascial planes during the deeper dissection. Once the entire decompression is complete, the surgical tourniquet is deflated to verify there are no hidden bleeding vessels. Under direct visualization, he confirms that all three primary terminal branches of the peroneal nerve are fully released and free of tension as they travel to their respective lower-leg muscle groups.
