The effect of oblique femoral tunnel placement on the knee using quadrupled hamstring graft
Journal Title: MedPulse -International Medical Journal - Year 2015, Vol 2, Issue 1
Abstract
Introduction: A common cause for failure after ACL reconstruction has been the incorrect placement of bone tunnels, especially on the femoral side resulting in a non anatomical graft. The most commonly employed technique of femoral tunnel placement, the trans-tibial technique, has been reported not to provide anatomical placement of femoral tunnel and result in rotational instability. Cadaveric and radiographic studies have confirmed that drilling the femoral tunnel through anteromedial portal allows a more oblique placement of the tunnel and higher rotational stability than does the trans-tibial technique. However clinical results of trans-tibial and anteromedial portal techniques are still controversial. A recent literature review showed improved rotational stability with oblique femoral tunnel technique but no difference in terms of clinical functions between the two techniques at mid and long term follow up. Very few other studies are available providing direct comparison between these two techniques.
