One month after minimally invasive knee surgery, adhesions usually do not occur, but they may occur if there is improper care and lack of rehabilitation exercises. Minimally invasive knee surgery has a small invasive surface, causes less damage to the skin, muscles, ligaments and other soft tissues of the human body, and results in shorter recovery time and less pain, and is less likely to result in adhesions after the surgery. However, if the postoperative care is not proper or the rehabilitation exercise is not carried out as soon as possible, adhesion of the knee joint may still occur. Therefore, after minimally invasive knee surgery, we should pay attention to balanced diet, nutrition, wound care, and functional exercises as prescribed by the doctor to prevent joint stiffness and soft tissue adhesion.
