A meniscus tear is typically accompanied by acute pain and tenderness on the joint surface, locking of the joint, giving way of the joint, weakness and swelling of the knee joint. Patients suffering from a meniscus tear often experience a sudden jolt of sharp pain or feel their knee giving way when they walk on stairs or on flat ground. Diagnosis can be made based on the patient's symptoms, physical examination, MRI, etc. X-ray alone cannot confirm a meniscus tear. Nevertheless, an X-ray is necessary to rule out other conditions e.g. Intra-articular loose bodies, debilitating osteochondritis dissecans (OCD).
