Can I still exercise after a meniscus tear?
Whether one can still exercise after a meniscus tear depends on the specific circumstances. If the tear is mild and in the recovery phase, appropriate exercise may be possible; however, if the tear is severe and in the acute phase, exercise should be avoided. Detailed analysis is as follows:

If the tear is relatively minor and the patient has achieved good recovery through conservative treatment, joint range-of-motion exercises and muscle-strengthening activities may gradually be initiated once pain and swelling have been controlled. These exercises should be performed under a doctor's supervision, following the principle of gradual progression, slowly increasing the intensity and range of motion.
For severe meniscus tears, especially those accompanied by significant pain, swelling, joint catching, or locking, patients should avoid all forms of strenuous activity, particularly high-impact movements such as running, jumping, or sudden pivoting and stopping. These activities may worsen the meniscus injury and potentially lead to permanent joint dysfunction.
During the recovery period, patients should avoid excessive weight-bearing activities to prevent further damage to the meniscus. Additionally, patients should take care to protect the knee joint in daily life to avoid re-injury.
