Flexing the knee after meniscus suturing does not usually disintegrate the sutures. The sutures used in meniscus suture surgery appear to be very thin, but are very tough and strong. The sutures at the meniscus suture site generally do not come apart when you do knee flexion. Functional exercises after meniscus suture need to be carried out under the guidance of the doctor. In the early postoperative period, pay attention to local braking and do not do knee bending activities too early, so as not to affect the recovery of the wound. Do a good job of joint protection to ensure the stability of the meniscus, which will help the healing of the meniscus. During the postoperative recovery period, when you can train the joint activities, the amplitude of knee bending activities should be gradual from small to large, when the amplitude is too large, it may pull the wound at the suture site, resulting in wound pain and even secondary injury. After meniscus suture surgery, you must follow the doctor’s instructions to do a good job of postoperative care, eat a balanced diet, maintain a happy mood, and actively cooperate with the doctor to carry out functional exercises, such as the emergence of uncomfortable symptoms, you should consult the doctor for review, so as to avoid delays in the condition.
