Variables Associated with Chondral and Meniscal Injuries in Anterior Cruciate Ligament Surgery.

This article aims to evaluate factors associated with chondral and meniscal lesions in primary and revision anterior cruciate ligament (ACL) reconstructions. ACL reconstructions from 2001 to 2008 at a single institution were retrospectively analyzed. Logistic regression was used to estimate the association between chondral and meniscal injuries and age, gender, tear chronicity, additional ligamentous injuries, sport type, and participation level.

The effects of extra-articular starting point and transtibial femoral drilling on the intra-articular aperture of the tibial tunnel in ACL reconstruction.

Background: The recent emphasis on more horizontal femoral tunnel placement for single-bundle anterior cruciate ligament (ACL) reconstructions requires placing a femoral tunnel lower on the lateral wall of the notch. Some surgeons have advocated moving the starting point of the tibial tunnel farther medial to achieve this more horizontal tunnel.

Purpose: To compare tibial tunnel aperture changes with transtibial femoral tunnel drilling.

Allograft reconstruction for massive, irreparable rotator cuff tears.

Background: There is currently no widely accepted treatment for massive, irreparable rotator cuff tears.

Hypothesis: Allograft reconstruction to span the remaining defect in massive, irreparable rotator cuff tears will lead to increased functional results and will demonstrate healing of the allograft on follow-up magnetic resonance imaging studies.

Study Design: Case series; Level of evidence, 4.

Anatomic endoscopic anterior cruciate ligament reconstruction with patella tendon autograft.

Current tibial endoscopic ACL reconstruction techniques provide functional stability, but fall short of the ultimate goal of ACL reconstruction, to restore normal knee kinematics. Vertical graft placement results in restoration of normal anteroposterior stability with a negative Lachman exam, but may not produce a stable knee in rotation, noted by a positive pivot shift. The Clancy anatomic endoscopic ACL reconstruction technique utilizes flexible reamers to achieve anatomic graft placement to more closely reproduce normal knee function.
