Meniscus repair surgery may have drawbacks such as nerve pain in the patient, infection in the joint area, and joint effusion. 1. Nerve pain: During meniscus repair surgery, the infrapatellar branch of the saphenous nerve may be damaged, or the patient’s joints already have problems before the surgery, and the patient may experience different degrees of nerve pain after the surgery. 2. Joint site infection: untimely surgery, incomplete hemostasis, etc. may affect the recovery of the joint, and may even cause local infection after surgery. 3. Joint effusion: excessive removal of meniscus, too early activity of patients after surgery and other reasons lead to poor local blood circulation, patients will experience joint swelling and pain, joint effusion and so on. If discomfort occurs after meniscus repair surgery, patients should consult a doctor in time for treatment. It is recommended that patients follow the doctor’s instructions to carry out rehabilitation training after surgery, do not blindly practice on their own resulting in serious consequences.
