Meniscal tears are divided into acute meniscal tears and chronic meniscal tears. Acute meniscal tears are usually the result of significant violence, with significant knee pain, limited range of motion and knee swelling at the time the tear develops. In chronic meniscal tears, there is no significant pain, and most develop over time with strenuous exercise or when the athlete is training heavily. Even if there is pain, there is only occasional mild tearing pain, which is not particularly noticeable, and the symptoms of limited range of motion and swelling in the knee are not particularly noticeable, so it is not possible to determine whether there is a meniscal tear by the symptoms of pain. Therefore, if you have knee discomfort, you should go to the hospital for an MRI of the knee to determine if there is a meniscus tear.
