Ligament reconstruction surgery is a complex procedure that has undergone many different variations of the procedure. Currently ligament reconstruction surgery has become a minimally invasive procedure that is done arthroscopically. Currently, instead of cutting into the joint, ligament reconstruction surgery only requires two holes to be made in the joint, through which an endoscope is placed into the joint and a new ligament is grafted in. This type of ligament reconstruction surgery involves the use of a ligament graft to replace the original torn ligament, such as a broken drawbridge, and the construction of a new drawbridge to connect the two ends, all that needs to be done is to fix the two ends of the drawbridge and make sure that the new drawbridge is strong enough to do the job, thus reconstructing the ligament and restoring the function of the original torn ligament. This graft can currently be an autologous ligament, where another ligament is removed from the body and grafted in to replace the original injured ligament, or it can be a donor ligament, which is a homogeneous allograft, or it can be a synthetic ligament, all as options. The surgeon chooses the right ligament for the surgery based on the patient’s condition, financial situation, and actual circumstances. Ligament reconstruction surgery is a minimally invasive, arthroscopic procedure that is complex but very minimally invasive, and can be completed in a few minutes to an hour. After surgery, patients can make early recovery, wear a brace to the ground, bear weight and move around early, and gradually return to normal life. With a good post-operative recovery, patients can resume physical exercise.
