    Journal: J Med Assoc Thai; 2009 Dec; 92 Suppl 6():S181-8. PubMed ID: 20120683.
    Abstract:
    OBJECTIVE: To identify the posterior laxity of the knee after PCL fixation and to correlate the findings with the functional outcomes using the standard evaluation systems. MATERIAL AND METHOD: Ten isolated PCL avulsions from tibial attachment were enrolled. The operation was done within 16 days after injury. Anatomical reduction and internal fixation with a screw of the avulsion fragment was done under direct vision and was confirmed by radiographs. The follow up evaluation was done at an average of 40 months after the indexed surgery. RESULTS: Injured-normal side laxity difference at an average of 2.4 mm was observed. According to IKDC knee ligament standard evaluation, two knees were graded normal and eight knees were graded nearly normal. The average Lysholm score was 91. Two knees were graded as an excellent outcome and 8 knees were graded good outcome. CONCLUSION: Despite mild laxity in the injured knee, the functional outcomes after fixation of the PCL avulsion were good to excellent.
