We reported two cases of compression neuropathy of the common peroneal nerve misdiagnosed and treated as lateral meniscus lesions.
Case 1. A 24-year-old man complaining both knee pain had visited a hospital and had been diagnosed as both lateral menicus lesions. He had accepted four times arthroscopic surgery on each knee in the hospital during 10 years. Because his pain remained unchanged, he visited our clinic in August 1997.
Case 2. A 24-year-old female had accepted arthroscopic meniscectomy for left lateral knee pain. Postoperative course was uneventful. Two years after the operation, she noticed left lateral knee pain and spastic feeling on the lateral aspect of her left leg. She visited the same hospital. She was diagnosed as having recurrence of lateral meniscus tear and was suggested operative treatment. She visited our clinic in April 1999.
We diagnosed these patients having a compression neuropathy of the common peroneal nerve and tried nerve blocks at compression site. Since the effect of the blocks was temporary, neurolysis was performed. The complaints of the patients disappeared in the evening of the operative day and they satisfied the results.
On differential diagnosis of lateral knee pain, it should be differentiate compression neuropathy of the common Peroneal nerve.
