Torn Meniscus Symptoms Test - A torn meniscus, a common knee injury, may cause symptoms such as pain, swelling, stiffness, and difficulty bending or straightening the knee. While physical examination and medical imaging like MRI are commonly used to diagnose a torn meniscus, there is no specific "test" that can definitively determine its presence. A healthcare professional, such as an orthopaedic specialist, will evaluate your symptoms, conduct a physical examination, and may order imaging tests to diagnose and assess the severity of a torn meniscus.
