title: [Comparative evaluation of the techniques and effects of RetroButton and Interference Screw in anterior cruciate ligament reconstruction].
abstract: OBJECTIVE
  To evaluate the difference between RetroButton and Interference Screw in Anterior Cruciate Ligament (ACL) Reconstruction.
  
  
  METHODS
  Ninety-seven patients with ACL rupture were treated by arthroscopic reconstruction with RetroButton and Interference Screw from June 2008 to December 2011. There were 54 males and 43 females with an average age of 27.5 years (range, 18-53 years). The preoperative magnetic resonance imaging (MRI) of all injured knees revealed the rupture of ACL. The average time from injury to surgery was 13.1 days (range, 6-20 days). All the patients were randomly divided into RetroButton group and Interference Screw group. And all the operations were performed under arthroscopy. Patients were instructed to walk with crutches and weight-bearing 4 weeks after operation. Walk without crutches was allowed 6 to 8 weeks after reconstruction and normal daily activities were gradually resumed.
  
  
  RESULTS
  The average follow-up was 54.6 months (range 48-60 months). No adverse biological reactions or infection ever occurred. There was no spontaneous rupture or laxity of graft. The average Lysholm knee score[(56.1 ± 7.9) vs (93.1 ± 6.1); (55.3 ± 8.5) vs (93.2 ± 5.7)], KT-1000 examination [(9.2 ± 1.8) vs (2.1 ± 1.4); (9.5 ± 1.7) vs (2.1 ± 1.5)], International Knee Documentation Committee (IKDC) subjective and objective score [(49.7 ± 5.9) vs (91.7 ± 5.0); (50.2 ± 6.3) vs (91.0 ± 6.1)] were improved significantly in both two groups (all P<0.01), and there was no significant difference between the two groups [(93.1 ± 6.1) vs (93.2 ± 5.7), P>0.05].
  
  
  CONCLUSIONS
  ACL reconstruction using RetroButton and Interference Screw are simple and effective, and can lead to good ligamentous stability and knee function. The two kinds of fixation methods have no significant difference in short and medium term effect. Long-term follow-up should be performed to confirm the durable stability of the knee.
