Torn meniscus is one of the commonest knee injury. It is caused by twisting injury of knee. It presents with pain in knee, swelling, stiffness and some time with locking. Pain is usually localized around the knee joint.
Patients feel pain while straightening of bent knee, while getting up or using stairs. Usually MRI is required to diagnose it. Conservative treatment with medicines, ice pack application and rest helps in reducing pain. Peripheral tears can heal but complex tears require meniscectomy. It is a keyhole surgery where torn portion of meniscus is removed with instruments through small hole.
