All of the articles about the knee joint published in this issue are related to minimally invasive surgery and accurate and precise techniques. Minimally invasive surgery and accurate and precise techniques are associated with each other. Minimally invasive surgery is the means to achieve precision, and precision is the premise of minimally invasive surgery, with the same purpose of best therapeutic effects and smallest surgical injuries. Therefore, they are often referred to as the“accurate, precise and minimally invasive surgery”, which is the target of modern joint surgery. The whole clinical medicine will enter a new era driven by the minimally invasive surgery, with the endoscopic surgical technique (minimally invasive surgery in the narrow sense) as the leader. However, minimally invasive surgery not only refers to an endoscopic technique, or just about reducing the body tissue damage, but also aims to minimize the mental and psychological trauma and burden for the patients and their families. With the precise preoperative evaluation, sophisticated surgical decision-making and delicate operation procedure, excellent results could be ifnally achieved in the accurate and precise surgery. The surgical treatment gets improved in 3 dimensions, including the treatment effectiveness, operation safety and minimally invasive intervention. Accurate, precise and minimally invasive surgery helps shape the future directions of the surgery, and with great prospects. We will certainly say goodbye to the former blood-shed ifght in the traditional surgery, and pursue the ultimate goal of accurate, precise and minimally invasive surgery together in the orbit of modern surgery with the increasingly sophisticated equipment and constantly updated concepts.
