• Risk of Tearing the Intact Anterior Cruciate Ligament in the Contralateral Knee and Rupturing the Anterior Cruciate Ligament Graft during the First 2 Years after Anterior Cruciate Ligament Reconstruction (2007) · doi

  BACKGROUND: The risk of tear of the intact anterior cruciate ligament in the contralateral knee after anterior cruciate ligament reconstruction of the opposite knee and the incidence of rupturing the anterior cruciate ligament graft during the first 2 years after surgery have not been extensively studied in a prospective manner.

• Lower Risk of Revision With Patellar Tendon Autografts Compared With Hamstring Autografts (2014) · doi

  BACKGROUND: A number of studies have found comparable results after anterior cruciate ligament (ACL) reconstruction with patellar tendon autografts and hamstring autografts; however, few studies have been large enough to reveal differences in risk of revision with regard to clinical and demographic factors.

• Rehabilitation after Anterior Cruciate Ligament Reconstruction: A Prospective, Randomized, Double-Blind Comparison of Programs Administered over 2 Different Time Intervals (2005) · doi

  BACKGROUND: There are adverse effects associated with immobilization of the knee after anterior cruciate ligament reconstruction, yet very little is known about how much activity will promote adequate rehabilitation without permanently elongating the graft, producing graft failure, or creating damage to articular cartilage.

• The Relationship between the Angle of the Tibial Tunnel in the Coronal Plane and Loss of Flexion and Anterior Laxity after Anterior Cruciate Ligament Reconstruction (2001) · doi

  Tension in an anterior cruciate ligament graft is greater with the knee in flexion when the angle of the tibial tunnel in the coronal plane is vertical or more perpendicular to the medial joint line of the tibia; however, the relationship of the angle of the tibial tunnel to knee function has not been studied.
