Median age was 22 years old (range, 17\u201340). Mean period from injury to operation was 15.1 \u00b1 18.2 weeks. Lysholm score, IKDC classification, range of motion (ROM) of knee, and side\u2010to\u2010side difference (SSD) in anterior instability were evaluated preoperatively and at the last follow\u2010up. Tegner activity scale was evaluated before injury and at the final follow\u2010up. The extent of synovialization of the graft was evaluated under second\u2010look arthroscopy at least 1 year after surgery. Formation of the synovial membrane was divided into four groups\u2014group 1 for 25% or less, group 2 for 25\u201350%, group 3 for 50\u201375%, and group 4 for more than 75%.
