title: A comparative study of two methods for treating type III tibial eminence avulsion fracture in adults.
abstract: OBJECTIVE
  Suture fixation is mostly used in arthroscopic treatment of tibial eminence avulsion fractures. However, no clinical studies of metal cable fixation have been reported. We hypothesised that cable fixation can provide equal stability and clinical outcome compared with Ethibond sutures.
  
  
  METHODS
  Between 2007 and 2008, we treated 42 patients of adult type III tibial eminence avulsion fractures. Twenty-three patients were male, and 19 were female. All patients were confirmed by radiographs, MRI, and arthroscopy during surgery. Ligament injury and meniscus tears were excluded from this study. Twenty-two patients were treated with No. 2 Ethibond suture fixation (group I), and 20 were treated with cable fixation under arthroscopy (group II). Follow-up assessments included imaging evaluation, Lysholm knee score, International Knee Documentation Committee (IKDC) classification, and the Lachman test.
  
  
  RESULTS
  Bone union was found in radiographic evaluation in all patients within 3 months. At the last follow-up, there was neither extension nor flexion limitation in any patient. There were no significant differences in the Lysholm score between the two groups at follow-up. All 42 patients were classified by the IKDC as normal or nearly normal. Stability based on the Lachman test showed two patients of grade II laxity in group I. At the final follow-up, all 42 patients had returned to their pre-injury activities.
  
  
  CONCLUSIONS
  Cable fixation to treat type III tibial eminence avulsion fracture can provide a clinical outcome equal to that of Ethibond sutures.
