Introduction: There are two techniques for reconstruction of anterior cruciate ligament (ACL), open technique and arthroscopic assisted technique. Arthroscopic assisted technique has many advantages over open procedure but it needs more expertise and cost comparatively.The objective of this study is to identify the clinical outcomes on basis of lyshlomknee score (LKS) system and find out patients satisfaction after performing both procedures in two groups separately. Material and Methods: Retrospective analysis of 600 patients undergoing open ACL reconstruction and arthroscopic reconstruction from 2005 to 2018 was done, at the Department of Orthopaedics, Ghurki Hospital, Lahore. We included all those patients who were 18 to 45 years of age and had at least 1 year follow up.
