There are three main types of meniscus examinations: the first is a specialist examination by a physician, which is a manual examination to detect meniscus damage. The main techniques used are the knee grind test and the knee hyperextension and hyperextension test, which are used to examine the site of meniscus damage. The second type of examination is imaging to determine if there is damage to the meniscus. The main test is an MRI of the knee, which can more clearly identify the extent and location of meniscus damage. The third type of examination is minimally invasive arthroscopy, which can be used to visually identify meniscal damage, the location and extent of the damage, and to provide systematic treatment.
