Introduction
Running can damage the meniscus. Patients with meniscal injury are typically unable to run. Specifically, if the meniscal injury is mild to moderate, immobilization and rest are required, along with functional exercises to facilitate gradual recovery. Running in such cases will not promote proper healing of the meniscus and may instead exacerbate the injury. In cases of severe meniscal injury or tear, arthroscopic surgery is necessary.

Nowadays, many people prefer engaging in physical exercise. Exercise itself is beneficial for both physical and mental health. Typically, you should perform warm-up activities before exercising to prepare your body for movement. Without proper warm-up, accidents may occur during exercise, potentially leading to injuries—among which meniscal tears of the knee are the most common. So, does running damage the meniscus?

Does Running Damage the Meniscus?

Yes, running can damage the meniscus. Patients with meniscal injury are generally advised against running. Specifically, if the meniscal injury is mild to moderate, immobilization and rest are required, along with functional rehabilitation exercises to gradually recover from the injury. Running under such conditions will not facilitate meniscal healing; instead, it may exacerbate the injury. In cases of severe meniscal tear or damage, arthroscopic surgery may be necessary. Running in these circumstances could worsen the tear, potentially causing severe joint locking symptoms, damaging articular cartilage, and resulting in irreversible joint injury with serious consequences.

Running is not recommended for individuals with meniscal injury. The meniscus is a fibrocartilaginous structure that protects the knee joint. It possesses elasticity and serves several key functions: absorbing impact forces across the joint, protecting the articular cartilage on the joint surfaces, increasing the contact area between the femur and tibia, and reducing friction. When the meniscus is damaged, its surface becomes irregular and rough. Engaging in high-impact activities like running under such conditions causes the roughened meniscal tissue to abrade the articular cartilage on both the upper and lower joint surfaces, leading to progressive cartilage wear. Therefore, running is contraindicated in cases of meniscal injury.

Patients are advised to maintain healthy lifestyle habits and follow a balanced diet, avoiding spicy and irritating foods. We hope this information proves helpful to you.
