title: Arthroscopic reduction and suture fixation of displaced tibial intercondylar eminence fractures in adults.
abstract: BACKGROUND
  Tibial intercondylar eminence fractures are uncommon. In a review of the literature, most authors agreed that conservative treatment was suggested for non-displaced fractures. Displaced fractures were considered an indication for surgery.
  
  
  METHODS
  Between April 2000 and November 2001, five adult displaced tibial eminence fractures were treated by arthroscopic reduction and non-absorbable suture fixation. Postoperatively, the knee was immobilized in a hinged knee brace locked in full extension with non-weight bearing for 4 weeks. Range of motion and quadriceps-strengthening exercises were started 4 weeks later. Partial weight-bearing was allowed in the following 4 weeks.
  
  
  RESULTS
  The average follow-up was 24.6 months (range 18-36 months). Subjectively, there was no instability or residual pain in the knee. The patients were able to resume their normal activities. Objectively, the average Lysholm Score was 95.6 (range 93-98). The average knee range of motion was 2 degrees to 135 degrees (range 0 degree-140 degrees). All patients had a negative Lachman's test and no pivot shift phenomenon. All fractures showed good union according to radiological evaluation.
  
  
  CONCLUSIONS
  Arthroscopy-assisted screw fixation is more stable, and it allows early exercise. However, the fragment must be large enough to be fixed with a screw. Comminuted or small fragments present limitations for screw fixation techniques. We used the non-absorbable intraligmentous suture to pull down the fragment regardless of small size or comminuted status. The technique is simple and provided secure fixation without damage to the ACL insertion. A second operation is not required to remove the hardware.
