The Multicenter Anterior Cruciate Ligament (ACL) Revision Study (MARS) group was formed to study a large cohort of revision ACL reconstruction patients. The purpose of this subset analysis study of the MARS database is to describe specific details of femoral tunnel malposition and subsequent management strategies that surgeons chose in the revision setting. The design of this study is a case se...

BACKGROUND At the time of anterior cruciate ligament (ACL) reconstruction, there are usually concurrent meniscal and articular cartilage injuries. It is unclear if there is a significant difference between intra-articular injuries at the time of a primary ACL reconstruction compared with revision ACL reconstruction. PURPOSE To compare the meniscal and articular cartilage injuries found at the...

CONTEXT Reconstruction of the anterior cruciate ligament (ACL) is one of the most common surgical procedures, with more than 200,000 ACL tears occurring annually. Although primary ACL reconstruction is a successful operation, success rates still range from 75% to 97%. Consequently, several thousand revision ACL reconstructions are performed annually and are unfortunately associated with inferio...

BACKGROUND Cartilage injury associated with anterior cruciate ligament (ACL) ruptures is common; however, relatively few reports exist on concurrent cartilage repair with ACL reconstruction. Autologous chondrocyte implantation (ACI) has been utilized successfully for treatment of moderate to large chondral defects. HYPOTHESIS ACL insufficiency with relatively large chondral defects may be eff...

Reconstruction of the anterior cruciate ligament (ACL) is widely accepted as the treatment of choice for individuals with functional instability due to an ACLdeficient knee. It is estimated that anywhere between 60,000 and 75,000 ACL reconstructions are performed annually in the United States, although this number may be as high as 350,000. Despite the fact that nearly 90% of index ACL reconstr...

Collateral ligament injury can be a cause of ACL graft failure. These ligament injuries must be addressed at revision surgery in order to prevent failure of the revision surgery. In malalignment with associated collateral ligament injury, osteotomy may be the preferred choice to manage the collateral ligament laxity. This outline will describe techniques for managing collateral ligament injury ...

BACKGROUND Anterior cruciate ligament (ACL) reconstruction with hamstring autografts less than 8.5 mm in diameter is associated with worse patient-reported outcome scores and increased risk of revision surgery compared with reconstructions performed with larger grafts. One proposed solution to small autograft harvest is to create a hybrid graft by augmenting autografts with allograft tissue to ...

Although double-bundle anterior cruciate ligament (ACL) reconstruction has theoretical benefits such as more accurate reproduction of ACL anatomy, it is technically more demanding surgery. This report describes the case of a one stage revision single-bundle ACL reconstruction after primary double-bundle ACL reconstruction. A professional dancer had an ACL previously reconstructed with a double-...

STUDY DESIGN Case report. OBJECTIVES To present a progressively increasing negative-work exercise program via eccentric ergometry early after anterior cruciate ligament reconstruction (ACL-R) and to suggest the potential of negative work to amplify the return of quadriceps size and strength. CASE DESCRIPTION The patient was a 26-year-old highly active recreational athlete who sustained an A...
