Knee ligament injuries are typical among athletes who engage in contact sports such as basketball, football, and soccer, and are categorized based on severity. Grade I involves minor damage and slight stretching, while grade II entails partial tearing. Complete tearing divides the ligament into two halves, causing instability in the knee joint, as in grade III injuries. When the ligament is completely torn, surgical repair involves grafting tissue from another part of the body or a donor. The damaged ligament is replaced by the graft and secured to the femur and tibia using metallic screws. Over a few months, the graft will heal.
Arthroscopic knee ligament reconstruction is a minimally invasive operation that is performed through a few small incisions. An arthroscope is inserted into the knee joint via one of the small incisions to provide a clear view of the surgical region (inside the knee) on a television screen for the surgeon. The surgeon then performs the procedure using tiny surgical instruments inserted through the other small incisions around the knee. Arthroscopic surgery has several advantages due to its small incisions, such as less postoperative pain, a shorter hospital stay, and a quicker recovery period.
After undergoing arthroscopic ligament reconstruction, most athletes can return to high-level sports after a rehabilitation period.
