title: Combined posterolateral corner reconstruction with remnant tensioning and augmentation in chronic posterior cruciate ligament injuries: minimum 2-year follow-up.
abstract: OBJECTIVE
  To evaluate functional results and knee stability after tensioning of remnant posterior cruciate ligament (PCL) with anterolateral (AL) bundle reconstruction and posterolateral corner (PLC) reconstruction in chronic PCL and PLC injuries.
  
  
  METHODS
  Between March 2001 and March 2007, 95 patients with chronic PCL injuries combined with PLC injuries underwent tensioning of the remnant PCL with AL bundle reconstruction and PLC reconstruction. Among these 95 patients, 70 who were satisfied with our inclusion were reviewed. The mean follow-up period was 40.1 months (range, 24 to 96 months). Tensioning of remnant PCL fibers was performed by distal transfer of the posterior tibial attachment. The AL bundle of the PCL was reconstructed by use of the modified inlay technique. The PLC reconstructive procedure was performed with a single sling through fibular tunnel. Stability was measured on posterior stress radiographs and by use of a maximal manual displacement test performed with a KT-1000 arthrometer (MEDmetric, San Diego, CA). The International Knee Documentation Committee and Orthopädishe Arbeitsgruppe Knie scoring systems were used for clinical evaluation.
  
  
  RESULTS
  Stress radiographs showed that the mean side-to-side difference (posterior tibial translation compared with that of the contralateral knee) was reduced from 10.3 ± 2.4 mm preoperatively to 2.2 ± 1.5 mm at the last follow-up (P < .001), whereas the KT-1000 tests showed that this difference was reduced from 8.4 ± 2.2 mm preoperatively to 2.0 ± 1.4 mm (P < .001). The final International Knee Documentation Committee objective score was A in 30 patients (42.8%), B in 34 (48.6%), and C in 6 (8.6%). The mean Orthopädishe Arbeitsgruppe Knie score improved from 63.5 ± 10.4 to 88.9 ± 7.6 (P < .001).
  
  
  CONCLUSIONS
  Excellent posterior stability and relatively good clinical results were achieved with tensioning of the remnant PCL and AL bundle and PLC reconstruction by use of fibular tunnel for patients with chronic combined PCL-PLC injuries.
