Knee dislocation: Treatment of high-velocity knee dislocation

Background: We report the outcomes of patients treated with a new arthrosco pic treatment modality for knee dislocation after high-velocity trauma, Methods: Twenty-three patients (12 men, 11 women; 25 knees) with traumatic knee dislocation were treated with this technique. Under arthroscopy with g ravity inflow irrigation, the ruptured posterior cruciate ligament was reco nstructed with a patellar bone-tendon-bone graft, and the anterior cruciate ligament was debrided subacutely, The collateral ligament, meniscus, and c apsules were repaired through additional incisions. Results: The average interval between injury and surgery was 11.1 +/- 5 day s (range, 5 to 25 days), After a mean follow-up period of 27.2 +/- 7.86 mon ths, the mean extension was 1 +/- 2 degrees and the average flexion was 129 .6 +/- 4.91 degrees, The mean Lysholm score was 84, There were no major com plications, Conclusion: Arthroscopic posterior cruciate ligament reconstruction seems t o be an effective treatment for traumatic knee dislocation.
