Anterior cruciate ligament (ACL) reconstruction surgery has significantly evolved in recent years. This has led to development of new technologies that facilitate the diagnosis of ACL injury and the application of state of the art methods for treatment. In particular, individualized anatomical ACL reconstruction aims to restore native ACL function. Treatment is tailored to each patient based on...

BACKGROUND Tibial fixation of hamstring tendon grafts has been the weak link in anterior cruciate ligament reconstruction. HYPOTHESIS Use of a central four-quadrant sleeve and screw provides superior fixation when compared with standard interference screw fixation. STUDY DESIGN Controlled laboratory study. METHODS In eight pairs of cadaveric knees each anterior cruciate ligament was recon...

Background: Recently, the surgical methods are used in patients with anterior cruciate ligament rupture and have been associated with successful results. There are different results in the term of using of the surgical methods for anterior cruciate ligament that often is associated with some complications such as infection, static laxity, remaining the pain, need to recurrence surgery, and limi...

OBJECTIVE To assess the presence of tibial bone tunnel enlargement after surgical reconstruction of the anterior cruciate ligament using quadruple graft of the flexor tendons and correlate the functional results in their presence. METHODS The studied lasted six months and included 25 patients, with ages ranging from 18 to 43 years old. Assessment was based on radiographs taken immediately pos...

Anterior cruciate ligament (ACL) reconstruction is common, with >100,000 procedures performed each year in the United States. Several factors are associated with failure, including poor surgical technique, graft incorporation failure, overly aggressive rehabilitation, and trauma. Tibial shaft fracture is also common and frequently requires operative intervention. Failure to reestablish the anat...

We read the article “Anatomical ACL reconstruction with double bundle: first 40 cases” by Zekcer A. et al [Rev Bras Ortop 2011;46(3): 262-5] with great interest and would like to make some comments on what was reported in that paper. The authors drilled an anteromedial femoral tunnel with the knee flexed at 90°. At this degree of flexion, the tunnel is significantly shorter than it is at flexio...

A 24 year old otherwise healthy male was presented with a chief complaint of giving way in the left knee. MRI reportedcomplete anterior cruciate ligament (ACL) tearing. Arthroscopy showed ACL agenesis, ring-shaped lateral meniscus,and an anomalous thick band extending from the anterior horn of the lateral meniscus to the intercondylar notch of thelateral femoral condyle, which...
