Outcome(s)

• Primary Outcome: Clinical results (Lysholm score)

Secondary Outcome

1.Clinical results (Tegner score, International Knee Documentation Committee (IKDC) score, The Knee injury and Osteoarthritis Outcome Score (KOOS) score, Visual analogue scale (VAS) of knee pain)

3.Radiological evaluation (femoral tibial angle, Kellgren Lawrence grade, Koshino stage, medial meniscal medial extrusion)
4.The adverse events; suture tears, infections
