Abstract:
BACKGROUND: Previous artificial ligament is easy to break for material fatigue and to appear synonitis for materialbiocompatibility.OBJECTIVE: To observe the application effect of ligament advanced reinforcement system (LARS) artificial ligament inreconstruction of anterior cruciate ligament via follow-up.DESIGN, TIME AND SETTING: An own control, follow-up observation was performed between August 2004 andJanuary 2007 at the Department of Orthopedics and Joint Surgery, Shanghai Changzheng Hospital, Shanghai, China.PARTICIPANTS: Twenty-eight patients with anterior cruciate ligament injury, including 16 with sport injury and 12 withvehicle accident injury.MATERIALS: The main component of LARS artificial ligament (Laboratoire d'Applieation et de Recherche Scientifique,France) is the high-tenacity polyester fiber polyethylene terephthalate.METHODS: Twenty-eight patients with anterior cruciate ligament injury were performed arthroscopic reconstruction of theligament with LARS artificial ligament and were averagely followed up for 20 months.MAIN OUTCOME MEASURES: Patients' anterior drawer test, Lysholm score, range of motion prior to transplantationand in follow-up.RESULTS: The knee unstable symptom of 28 patients disappeared, anterior drawer test was negative, joint function wasgood with the flexion of 5.71 to 129.64 degrees. Average Lysholm score raised from (45.7±9.82) points prior totransplantation to (86.5±6.44) points after transplantation (P < 0.001). All patients resumed normal activities at 2 monthsafter transplantation, without acute or chronic synovitis and host response to materials.CONCLUSION: LARS artificial ligament is a relatively safe transplantation material and especially suitable to reconstructanterior cruciate ligament with sport injury. Mid-/short-term follow-up shows good result.
