More than 500,000 knees are replaced each year in the US. In 2010, more than 4.5 million US citizens are living with a knee replacement. Knee replacement is the 14th most common inpatient surgical procedure. While this type of surgery is very successful, and reduces or eliminates pain in most cases, there are reports that 10%-34% of patients develop chronic post-operative pain after knee replacement surgery. (J. Pain Res, 2013;6:691-703).

Why does this happen?
It is not because the surgeon who replaced your knee did anything wrong, but that this nerve does not have a large amount of space to course though anatomically around the knee, and with manipulation of the leg during the knee replacement surgery, and post-operative swelling, the Common Peroneal Nerve is highly susceptible to developing an entrapment (pinching) that causes continued post-operative pain.
What can be done?
We can quickly and accurately determine if this is the cause of pain for the patient, and then make a treatment recommendation. If we recommend surgery based on our evaluation, it is an outpatient procedure that takes less than 20 minutes to perform, and the patient is allowed to be fully weight bearing that same day.
