Risks and Consequences of Using the Transportal Technique in Reconstructing the Anterior Cruciate Ligament: Relationships Between the Femoral Tunnel, Lateral Superior Genicular Artery and Lateral Epicondyle of the Femoral Condyle

Abstract

Objective: Define a security zone to avoid possibles vascular and ligamentar complications during anterior cruciate ligament reconstruction. Methods: Arthroscopic reconstruction using the transtibial and transportal technique in cadaver knees was performed followed by dissection and measurement of the distance between the femoral tunnel and the proximal attachment of the lateral collateral ligament and the femoral tunnel and the lateral superior genicular artery. Results: The measure of the analysed distances show us an aproximation between the major branch of the lateral superior genicular artery and the femoral insertion of the colateral lateral ligament and the femoral tunnel during the transportal technique. Conclusion: We realize that the use of technical ship it to arthroscopic ACL reconstruction has a higher probability of injury to the lateral geniculate artery and insertion of the lateral collateral ligament, promoting post-surgical complications such as instability of the knee, osteonecrosis of the femoral condyle and ligamentização graft.

Identification of Suitable Reference Genes for Investigating Gene Expression in Anterior Cruciate Ligament Injury by Using Reverse Transcription-Quantitative PCR

“…The anterior cruciate ligament (ACL) is an important structure in the knee and is one of the most frequently injured structures during high-impact sporting activities [ 1 , 2 , 3 ]. The ACL does not heal following lesions, and surgical reconstruction is the treatment of choice in most cases [ 4 , 5 ]. Reconstructive surgery aims to restore the kinematics and stability of the injured knee, which allows a return to sports and may help to prevent osteoarthritis in the long term [ 3 , 5 , 6 , 7 ].…”

Reconstruction of the anterior cruciate ligament: comparison of analgesia using intrathecal morphine, intra-articular morphine and intra-articular levobupivacaine

“…A considerable variety of techniques and materials are used in it. 3 In the United States, approximately 175,000 reconstructions involving this orthopedic operation are performed every year. ACL reconstruction has now become a worldwide practice 4 and is increasingly being performed as an outpatient procedure.…”
