Does the position of the femoral tunnel affect the laxity or clinical outcome of the anterior cruciate ligament-reconstructed knee? A clinical, prospective, randomized, double-blind study.

Purpose: The aim of this study was to evaluate whether a change in the femoral graft insertion site between the 1-o'clock (high) and 2-o'clock (low) positions could change the laxity, the score on the 2000 International Knee Documentation Committee (IKDC) Knee Examination Form, or the score on the 2000 subjective IKDC Knee Evaluation Form in the anterior cruciate ligament (ACL)-reconstructed knee.

Methods: The study was designed as a prospective, randomized, double-blind investigation. We randomized 30 patients to the low tunnel position group and 30 to the high tunnel position group.

Radiolucency adjacent to the tibial component in total knee arthroplasty.

This study determined the accuracy of standard radiographs in observing radiolucency adjacent to the tibial component in total knee arthroplasty. A model of the proximal tibia was used. Plastic sleeves of different heights were glued under the tibial tray to imitate radiolucency.
