The repair methods for joint and ligament injuries include the following: first, direct suturing of the ligaments, which is mainly applicable to patients with ligamentous body tears in the early stages of the injury and no ligamentous defects, which can be incised in the early stages of the injury and direct repair suturing of the ligaments, most of which can have good results. Second, ligament reconstruction can be performed. For ruptures of the anterior and posterior cruciate ligaments, minimally invasive arthroscopic surgery is currently advocated to perform ligament reconstruction surgery, which can restore the integrity of the ligaments, restore the stability of the knee joint, and restore the normal function of the knee joint. For tears of the medial and lateral collateral ligaments of the knee, ligament reconstruction can be considered if there is a severe defect or if direct suturing is not possible. Third, bone rivet sutures can be used to close the medial and lateral collateral ligaments with bone rivets at their stop points, which can also be very effective.
