| Abstract: | Objective To evaluate the usefulness of MR imaging for diagnosing the meniscal dislocation in the knee joints. Methosd MRI findings of 20 patients whose clinical symptoms were mainly knee pain and with surgically proved meniscal dislocation in the knee were analyzed retrospectively. Results Among 20 patients, the meniscal dislocation with tear was found in 15, while the meniscal dislocation with osteoarthritis was found in 14. On articular surface of the knee, meniscal dislocation with tear presented as slight hyperintense on T2WI and isointense on T1WI. Conclusion MR imaging can provide very reliable informations in the evaluation of meniscal dislocation in the knee. |
