Peroneal Nerve release surgery

My son had critical sepsis in Dec.  He has recovered medically but has peripheral neuropathy - both legs (more mild in arms).
He has no dorsi flexion.  The cause may have been the illness itself, the circulatory collapse or the rapid weight gain and loss.  One dr, a peripheral nerve specialist wants to do peroneal nerve release.
he has positive tinel.  He has had EMG studies.
I understand this is relatively new.  How do we decide?
Thank you

If the peripheral nerve symptoms started at the time of the critical illness, this could simply be critical illness polyneuropathy. It is possible that in addition to this he developed a peroneal nerve injury, the most common location is at the lateral aspect of the leg. A EMG of the leg with specific attention to the peroneal nerve may be able to determine if this nerve is injured, and where. If the EMG simply shows a more generalized process, then surgery may not be helpful. Without examing your son and reviewing the EMG's I can not provide a answer. If you are uncertain, I would recommend obtaining a second opinion at academic center. Good luck.
