Knee pain can affect people of all ages, not only older adults. It is also commonly found among office workers, athletes, and those who exercise regularly. When knee pain occurs, an X-ray is often the first imaging test performed. Although X-rays are effective for detecting bone abnormalities, they do not clearly show soft tissues such as ligaments, menisci, or cartilage.
MRI, or Magnetic Resonance Imaging, uses a magnetic field to produce detailed images of the structures inside the knee joint. It can assess the anterior and posterior cruciate ligaments, menisci, tendons, muscles, cartilage, bone marrow edema, and inflammation within the joint.
An MRI may be appropriate for individuals with symptoms such as:
- Knee pain lasting several weeks that does not improve with rest or treatment
- Knee swelling, fluid in the joint, or pain following an injury
- Knee locking or an inability to fully bend or straighten the knee
- A feeling that the knee is unstable, weak, or giving way while walking or playing sports
- Suspected ligament tears, meniscus injuries, or cartilage damage
MRI findings can help doctors make a more accurate diagnosis and develop an appropriate treatment plan. Treatment may include physical therapy, injections, non-surgical management, or surgery when medically indicated. This can help reduce unnecessary treatment and improve the likelihood of returning to normal knee function.
An accurate diagnosis is the first step toward treating the underlying cause. When knee pain interferes with daily activities or does not improve after initial care, it is advisable to consult a doctor for an assessment and to determine the most appropriate examination and treatment plan.
