Aetiology
A tear of the meniscus is a common injury that can occur from any activity that involves twisting, such as squatting, kneeling, running, or jumping. It can also occur as a result of aging, when the meniscus becomes weaker and more prone to tears.
Diagnosis
A tear of the meniscus is usually diagnosed through a physical exam and imaging tests such as X-rays, MRI, or CT scans. The doctor may also order an arthroscopy to confirm the diagnosis.
Differential diagnosis
Other conditions with similar symptoms to a meniscus tear include ligament sprains, arthritis, and bursitis.
Treatment
Treatment for a meniscus tear depends on the severity of the injury. Mild tears may heal without surgery, while more severe tears may require arthroscopic surgery to repair the tear. Physical therapy may also be used to help the patient regain strength and range of motion.
Prognosis
The prognosis for a meniscal tear is generally good, provided the injury is treated promptly and correctly. Most patients are able to return to their pre-injury activities within 4-6 weeks. However, if the tear is severe, the recovery may take longer.
