Eleven patients (14 joints) of hypermobile meniscus were treated in our hospital in the last 6 years approximately. Their mean age was 16 years with a range from 13 to 22 years, and 4 patients were male and 7 patients were female. An affected side of meniscus was all lateral. Only 3 patients had traumatic episode on the knee joint. Giving way was seen in all patients but locking was seen in only one patient. McMurray test was positive in the majority of patients, but Apley test was positive in only one patient.The tendency of general joint laxity was seen in 6 patients (3 patients showed involvement in bilateral knee joints). These were considered to be characteristic findings and one of the geneses of hypermobile meniscus.Arthroscopic partial meniscectomy was performed in 6 patients (8 joints) and arthroscopic meniscoresis in 5 patients (5 joints). These results were more satisfactory in the cases of arthroscopic meniscoresis than the cases of arthroscopic meniscectomy. So, arthroscopic meniscoresis should be chosen in the case of hypermobile meniscus requiring surgery.
