Abstract

PURPOSE
To introduce the modified tibial inlay technique and evaluate the clinical results of 44 patients who underwent PCL reconstruction by this method and were followed-up for more than 2 years.
MATERIALS AND METHODS
The clinical results were assessed using the Orthopadishe Arbeitsgruppe Knie (OAK) and International Knee Documentation Committee (IKDC) knee scoring systems. The integrities of the reconstructed PCLs were assessed using posterior stress radiographs and the manual maximum displacement test using a KT-1000 (TM) arthrometer.
RESULTS
The average 65.8+/-9.4 OAK score, 10.8+/-4.6 mm displacement by stress radiographs and 9.4+/-4.1 mm displacement by KT-1000 (TM) arthrometer, were improved to an average 87.5+/-7.8, 3.4+/-0.4 mm, 2.7+/-0.9 mm, respectively, at the last follow-up. By the IKDC and OAK scoring systems, 35 cases (79%) and 40 cases (90%), respectively, showed satisfactory clinical outcome. A second arthroscopic examination was performed in 20 of 44 cases. No case showed rupture of the grafted tendon. However, 3 cases showed recurrence of posterior instability, which requried a retightening at the tibial bone block site.
CONCLUSION
The modified tibial inlay technique may improve the quality of outcome of arthroscopic PCL reconstruction, because this technique can avoid grafted tendon abrasion at the posterior orifice, and this preserve the remnant PCL bundle, and it allows the retightening of loose grafted tendon to be performed easily.
