Abstract
Injury or entrapment of the infrapatellar branch of the saphenous nerve (IPS) can cause persistent anterior and medial knee pain. However, IPS neuralgia because of bullous morphea is rare and not reported earlier. We present a case of IPS neuralgia after total knee replacement where the pain was attributed to local skin lesion of bullous morphea (BM). After a successful diagnostic block, radiofrequency treatment was done to provide prolonged relief. We have discussed the possible pathogenesis of nerve entrapment and pain by BM in our case and the basis of treatment by radiofrequency ablation.
