title: Benign synovioma causing internal derangement of the knee. A report of nine cases.
abstract: Nine pedunculated benign synoviomata causing mechanical symptoms similar to those of a torn meniscus are described. The average age of the patients was 34.4 years. During the period of study, 2254 meniscal lesions causing mechanical symptoms were identified, giving an incidence of one benign synovioma for every 250 meniscal lesions. All the lesions were removed arthroscopically with relief of symptoms.
