Abstract：Objective:We presented our experience on the diagnosis and treatment of common peroneal nerve intraneural ganglion cyst at knee joint in three cases and relevant literatures were reviewed. Methods:From 2011-2012, 3 patients who were affected with common peroneal nerve intraneural ganglion cyst at knee joint accepted surgery in our department. Intraneural ganglion cysts were found within the common peroneal nerve. Cyst decompression was done in three cases. Two of them were found intraneural ganglion cyst underlying distal descent into the terminal braches of common peroneal nerve and these branches were ligated.Results:After 9-15 months(mean: 11.3 months) follow-up, The symptoms of numbness and pain were recovered in three months. The muscle power of anterior Tibialis muscle was improved to 4 degree in 2 cases and 3 degree in the third case. There were no sign of intraneural ganglion cyst recurrence observed.Conclusions:Intraneural ganglion cyst involved common peroneal nerve at knee joint is rare. For patients who have clearly clinical diagnosis, surgical decompress is an effective treatment.
