Anterior cruciate ligament (ACL) rupture is one of the most common ligament injuries. There are a lot of surgical treatments related to ACL injury today. Although the most common treatment for ACL rupture is reconstruction, the discussions about optimal timing of surgery are ongoing. Previous authors submitted that early reconstruction can facilitate the return to work or sports in the early period, however, it may suggest that it may increase the incidence of postoperative complications such as arthrofibrosis. If the ACL rupture would not be treated (reconstructed) surgically, there is a high probability of developing internal meniscus tears and cartilage damage in the knee. Decreasing in range of motion that may develop after surgical treatment (arthrofibrosis) is a feared complication. Although there are some publications which indicated increased risk of arthrofibrosis on early surgical treatment, recently published paper works stating there is no significant difference between early or late surgical treatment as well. This study looks over the literature systematically to determine whether ACL reconstruction will be carried out acutely after rupture.
