Abstract:
Objective To discuss the operation skills and clinical effects of C-arm fluoroscopy in arthroscopic reconstruction of anterior cruciate ligament(ACL)with the Ligament Advancement Reinforcement System(LARS)artificial ligaments.Methods The study involved 36 patients with acute ACL rupture treated with the LARS artificial ligaments from June 2006.There were 25 males and 11 females,at age range of 22-51 years(average 28.3 years),involving 19 left knees and 17 right knees.The results of preoperative MRI of all patients suggested discontinuation of ACL,with average score of Lysholm on knee joint for 50.The operation was completed under arthroscope.While the locations of the femoral tunnel portal and the tibial tunnel exit were mainly determined by the C-arm fluoroscopy.The diameter of the LARS artificial ligament was 7.5 mm while that of the interference screw 8 mm.Results All 36 patients were followed up for a mean duration of 18 months(9-20 months).The average Lysholm Score was 52 preoperatively and 92 at the 12th week after operation.The clinical results were graded as excellent in 23 patients,good in nine and fair in four according to the Lysholm's classification,with excellence rate of 89%.Conclusions Arthroscopic reconstruction of anterior cruciate ligament with LARS artifical ligament under C-arm fluoroscopy takes advantages of convenient operation,accurate location and satisfactory clinical effect.
