title: [Arthroscopic treatment for tibial eminence avulsion fracture using absorbable double suture anchors].
abstract: OBJECTIVE
  To investigate the outcomes of arthroscopic reduction and internal fixation of tibial eminence avulsion fracture using absorbable double suture anchors.
  
  
  METHODS
  Between February 2007 and August 2009, 18 patients with tibial eminence avulsion fracture were treated with arthroscopic reduction and fixation using absorbable double suture anchors. There were 12 males and 6 females with an average age of 30.6 years (range, 17-48 years). The disease causes were traffic accident injury in 4 cases, sport injury in 8 cases, and falling from height injury in 6 cases; the locations were left side in 7 cases and right side in 11 cases. The results of the anterior drawer test and Lachman test were positive. According to Meyers-McKeever classification, 10 cases were rated as type II, 7 as type III, and 1 as type IV fractures. The time from injury to treatment was 6-20 days (mean, 10.2 days).
  
  
  RESULTS
  Incision healed primarily. All the patients were followed up 29.1 months (range, 13-43 months). The X-ray films showed good reduction of fracture immediately after operation and fracture healing at 3 months. At the last follow-up, the range of motion of knee was 0-130 degrees. The results of Lachman test and anterior drawer test were negative in 18 cases and 16 cases, respectively; and the results of anterior drawer test were weakly positive in 2 cases. The mean Lysholm score was significantly improved from 53.9 +/- 6.7 preoperatively to 91.6 +/- 4.2 postoperatively (t = 22.100, P = 0.000). The International knee Documentation Committee (IKDC) 2000 subject score improved from 58.1 +/- 3.7 preoperatively to 92.8 +/- 5.9 postoperatively (t = 20.700, P = 0.000).
  
  
  CONCLUSIONS
  Arthroscopic treatment using absorbable double suture anchors for tibial eminence avulsion fracture can provide satisfactory reduction, stable fixation, and good healing of the avulsed fragment, which is a minimally-invasive, simple, and effective treatment for patients with tibial eminence avulsion fracture.
