Normal walking and other daily life functions can be resumed 1~2 months after discoid meniscectomy, but it is better not to do too intense exercise in 1~2 years. Discoid meniscus is a deformity in which the meniscus is enlarged and thickened, with more deformities on the outer side than on the inner side. After 1~2 months of recovery after meniscectomy, you can start to resume normal function of daily life, but it is still better not to play too intense sports (such as soccer, basketball and other sports) for 1~2 years. The removal of discoid meniscus is mainly performed under knee arthroscopy. After the surgery, it is still important to limit the activities of the knee joint to speed up the healing after the surgery. And it is also important to perform rehabilitation exercises under the doctor’s supervision early after the surgery, mainly to prevent stiffness of the knee joint. After discoid meniscectomy, you should follow the doctor’s instructions to carry out activities and functional exercises, not blindly exercise on your own to avoid delaying the condition.
