What are the symptoms of a meniscus injury

The meniscus is a cartilage structure located between the thighbone and shinbone, acting as a shock absorber and load distributor within the knee joint. Sudden twisting, squatting, changing direction during sports, or gradual degeneration over time can lead to microtears in the meniscus fibers. The tear may be traumatic or degenerative, and the location and mechanism of pain provide important clues. The inner meniscus is more commonly affected because it is more stable on the tibia and more exposed to rotational stress. In the first few hours, sharp pain that worsens with movement and pain on the inner side of the knee, especially when climbing stairs or squatting, are typical. At the time of injury, a popping sensation may be felt inside the joint, followed by gradual swelling and decreased range of motion. Some people experience catching, locking, or instability while walking, and pain may worsen after sitting for long periods. Accompanying ligament injuries can make the condition more severe, so detailed examination is essential.

Meniscus symptoms and diagnosis

The most common symptoms are localized knee joint line pain, pain increasing with activity, a stabbing sensation when going up or down stairs, and occasional locking of the knee. Locking occurs when a piece of torn cartilage becomes trapped in the joint, preventing full extension of the knee and often requiring urgent evaluation. Morning or end-of-day stiffness, clicking or popping sounds, swelling after sports, and a feeling of fullness in the knee the next day are also frequent complaints. On physical examination, joint line tenderness and positive McMurray or Apley tests help confirm suspicion. The standard diagnostic method is MRI imaging, which shows the location, type, and any associated cartilage or ligament damage. X-rays are used to assess bone structure and arthritic changes. Differential diagnoses include patellofemoral pain, plica syndrome, loose bodies, and early osteoarthritis. Small, asymptomatic MRI findings do not always correlate with clinical symptoms; therefore, imaging must always be interpreted alongside medical history and examination.

Meniscus treatment, rehabilitation, and prevention

Treatment aims to reduce pain, restore function, and prevent recurrence. In the acute phase, rest, ice application, elastic bandaging, and limited weight bearing are the first steps. Short-term medication may help control pain but should not be used long-term. The foundation of recovery is a structured rehabilitation program. Strengthening the quadriceps and hamstrings, balancing the hip abductors and external rotators, and performing flexibility and proprioception exercises improve load distribution across the knee joint. In small, stable tears without mechanical symptoms, conservative management is often sufficient. Persistent locking, catching, increasing pain during activity, or functional loss may require arthroscopy for repair or limited meniscectomy; modern approaches prioritize meniscus preservation whenever possible. Preventive strategies include gradually increasing training load, proper technique during direction changes, using supportive shoes, and doing balance exercises. Maintaining a healthy weight helps reduce pressure on the joint. Warning signs such as sudden swelling, locking, inability to bear weight after injury, or nighttime pain require prompt orthopedic assessment. With an accurate diagnosis, a personalized treatment plan, and disciplined rehabilitation, most meniscus injuries can heal successfully without surgery, enabling a safe return to daily activity or sports.
