The sequelae of meniscus suture surgery mainly include limitation of knee joint activities, pain and swelling, accelerated degenerative changes, etc. However, with good selection of indications for the surgery and good selection of surgical methods, the general postoperative recovery effect is better and there will be no obvious sequelae. 1. Restriction of activities: If the knee joint is fixed for a long time after surgery and lack of rehabilitation training, it is easy to cause adhesion in the joint cavity, stiffness of the knee joint and restriction of flexion and extension activities. 2. Pain and swelling: after surgery, there may be swelling of the knee joint, pain in activities, etc. At the same time, the meniscus may not heal well. 3. Degenerative changes: After suture surgery, although the meniscus has been well repaired, its integrity is still damaged and the function of cushioning external forces is weakened, which may accelerate the degenerative changes of the knee joint and increase the risk of arthritis. For patients who undergo meniscus suture surgery, as long as the indications for surgery are well selected and the surgical method is well chosen, the general postoperative recovery effect is relatively good. It is recommended to pay attention to rest after the operation, and follow the doctor’s instructions to carry out rehabilitation training, which is conducive to the recovery of meniscus function. If there is any discomfort in the knee joint, it is recommended to consult a doctor in time to avoid delaying the condition.
