Objectives: Meniscal tears are one of the common knee injuries. Large size of longitudinal-vertical tear is called bucket handle tear, and easily displaced and locked in the knee joint cavity. This type of injury is usually required arthroscopic intervention due to pain or dysfunction such as loss of range of motion of the knee. Recently, the arthroscopic meniscal repair technique and devices have been developed and reported good results. The inside-out technique, outside-in technique, and all-inside technique are well known. However, 20 to 34.2% of failure cases after primary meniscal repair were reported. The purpose of this study is to identify the risk factors to associate with the postoperative failure of bucket handle meniscal tear under multi-center study. Methods: Patients The present study was conducted in 2021, involving patient who was diagnosed and performed primary arthroscopic meniscal repair surgery for bucket handle meniscal tear at four orthopaedic centers. The study followed retrospective observational design including data collected from Jan 2000 to Aug 2021. The experimental design was reviewed and approved (Accession No. 0-0956) by the Ethics Committee of our institute. The procedures followed were in accordance with the ethical standards of the responsible committee on human experimentation (institutional and national) and with the Helsinki Declaration of 1975, as revised in 2000. Inclusion criteria were the cases of knee bucket handle meniscal tears which were diagnosed clinically and by MRI testing. Exclusion criteria were following; postoperative observation period was less than 12 months cases, meniscal posterior root tear cases, could not obtain full surgical and clinical information cases, infection and inflammatory disease cases, and meniscal resection cases. Senior orthopaedic surgeons were diagnosed and performed arthroscopic surgery in each center. Surgical and clinical information were obtained from four orthopaedic centers. Total 95 bucket handle tear cases were enrolled in this study. Patients were analyzed on an average of 27.14 ± 24.8 months after surgery by the use of Marx score (MS) and Tegner Activity Scale (TAS). To identify factors associated with postoperative failure, we obtained the following information; age, body mass index (BMI), height, weight, injury to surgery duration, postoperative immobilization period, postoperative non-weight bearing period, timing of full-weight bearing, timing of running, presence o
