Regeneration of hamstring tendons after anterior cruciate ligament reconstruction

Principles for using hamstring tendons for anterior cruciate ligament reconstruction.

The use of autogenous hamstring tendon as a graft source for anterior cruciate ligament (ACL) reconstruction continues to gain in popularity. The low harvest morbidity and excellent biomechanical graft properties coupled with improved fixation of soft tissue grafts are all reasons for excellent clinical outcomes of ACL reconstruction using hamstring tendons. In addition, surgeon awareness of th...

Strength and Regrowth of Hamstring Tendons After Hamstring Autograft Anterior Cruciate Ligament Reconstruction

Much controversy exists regarding the potential advantages and disadvantages of various graft choices for anterior cruciate ligament reconstruction. Advocates of hamstring autografts often cite the limited apparent morbidity associated with semitendinosus or semitendinosus and gracilis harvest, including evidence that hamstring tendons may regenerate after harvest. In this article, we attempt t...

Anterior Cruciate Ligament Reconstruction with Hamstring Tendons Has no Deleterious Effect on Hip Extension Strength

Background: Hamstring tendons are secondary hip extensors. Their harvest for graft in anterior cruciate ligament(ACL) reconstruction may create deleterious effect on hip extension strength. This is of particular importance in sportsthat need powerful hip extension force like climbing and sprinting. Due to scarcity of a comprehensive study in thisarea, we designed this prospect...

MRI evaluation of medial hamstring tendons after harvesting for anterior cruciate ligament reconstruction

Anterior Cruciate Ligament Reconstruction With Autologous Hamstring

BACKGROUND Recent clinical investigations have identified inadequate autograft hamstring graft diameter (<8 mm) to be predictive of failure after reconstruction of the anterior cruciate ligament (ACL). PURPOSE/HYPOTHESIS The objective of this study was to determine the utility of preoperative magnetic resonance imaging (MRI) variables of the hamstring tendons for the prediction of graft diame...
