Mechanical Aspects of an Interference Screw Placement in ACL Reconstruction
نویسنده
چکیده
The physical status of an interference screw fixation in an anterior cruciate ligament (ACL) reconstructive surgery is a crucial factor of success. In this study, the insertion of the interference screw into a tibial bone tunnel, and the advancement of the screw between the tendon strands were investigated using both experimental and computer modeling. The mechanical behavior of the bone and soft tissue during the screw insertion, and the effect of the misalignment of the screw in the bone tunnel were investigated. Both concentric and eccentric placements of the screw were closely monitored and the results of both cases were compared.

Background: Ligament reconstruction is a common procedure in orthopedic surgery. Although several popular techniques are currently in use, new methods are proposed for secure fixation of the tendon graft into the bone tunnel. Purposes: We sought to introduce our new technique of Bashti bone plug for fixation of soft tissue graft in anterior cruciate ligament (ACL) reconstruction and to compar...

متن کاملExperimental and numerical analysis of screw fixation in anterior cruciate ligament reconstruction
This paper reports the results of an experimental and finite element analysis of tibial screw fixation in hamstring ACL reconstruction. The mechanical properties of the bone and tendon graft are obtained from experiments using porcine/calf bones and tendon. The results of the numerical study are compared with those from mechanical testing. Analysis shows that the model may be used to establish ...

OBJECTIVES We investigated the biomechanical characteristics of anterior or posterior tibial tunnel placement of the soft tissue graft with a soft tissue interference screw in anterior cruciate ligament (ACL) reconstruction. METHODS Twelve bovine tibiae and digital extensor tendons were divided into two homogeneously equal groups after they were stripped of all soft tissues. Tibial tunnels we...
متن کاملBroken Bioabsorbable Tibial Interference Screw after Anterior Cruciate Ligament (ACL) Reconstruction using a Semitendinosus-gracilis Graft: A Case Report.
ABSTRACT When a patient presents with knee pain and locking after an anterior cruciate ligament (ACL) reconstruction, a new meniscal injury or an osteochondral loose body are usually considered for differential diagnosis. We present the case of a 22-year-old female with just these complaints 6 months after ACL reconstruction surgery. Magnetic resonance imaging (MRI) of the knee showed a broken ...
