Peroneal tendoscopy and report on anomalies diagnosed

This is a report of two cases of anomalies associated with peroneal tendons detected by peroneal tendoscopy. There has been only one report on use of endoscopy to diagnose and treat peroneal tendon disorders. We have started using peroneal tendoscopy in our practice. We diagnosed two anomalies using this technique. The anomalies of peroneus quartus and abnormally low muscle belly on peroneus brevis tendons in these cases were not evident on the MRI scans. The diagnosis was confirmed only after peroneal tendoscopy. The technique of peroneal tendoscopy is described. Peroneal tendoscopy is a useful tool in diagnosis of peroneal tendon pathology.
