The Functional Outcomes of Delayed Surgical Reconstruction in Nonsport-Induced Multiligament Knee Injuries: A Retrospective Cohort Study

摘要

Multiligament knee injuries (MLKIs) are among the most detrimental injuries, which can cause significant compromise of joint stability and function. Our aim was to investigate the functional outcomes of nonsport-induced MLKIs who presented late after injury and underwent delayed arthroscopic reconstruction. In a retrospective cohort of 18 MLKI patients (19 knees, January 2012–2018) who had undergone arthroscopic reconstruction, we assessed the knee range of motion, return to work/sport, International Knee Documentation Committee (IKDC), Knee Injury and Osteoarthritis Outcome Score, Western Ontario and McMaster Universities Arthritis Index, Lysholm, and Tegner scores. The preoperative scores were retrieved from the patients' registry database. We reviewed their surgical notes and extracted the operation data, including the damaged ligaments, stages of the surgery, and associated meniscal injury. There were 14 males and 4 females with a mean age of 30.57?±?10.31 years. The mean time from injury to surgery was 17.31?±?11.98 months. The most common injury was anterior cruciate ligament/posterior cruciate ligament (31.6). The mechanisms of injury were motor vehicle accidents (72.2), falls (22.2), and sports (5.6). The reconstruction was either single (61.2) or multiple stage (38.8). The pre- and postoperative scores were 45.31?±?7.30 versus 79.16?±?11.86 IKDC, 3.84?±?1.26 versus 8.37?±?1.16 Tegner, and 60.42?±?7.68 versus 89.42?±?8.81 Lysholm, respectively. All the scores showed significant improvement at mean follow-up of 24.05?±?9.55 months (p?
