The cause of persistent symptoms after menisectomy has been assessed clinically, radiologically, arthrographically, and arthroscopically in 10 cases. The commonest findings was the retained fragment of posterier sggment in meniscus. In the largest patient group of our material, the symptoms were caused by a remnant of the operated meniscus. A remnant greater than a half of the length of the original meniscus segment often causes recurrent symptoms, which have been relieved by a second complete menisectomy in our experience.
