BACKGROUND The autograft preparation process for anterior cruciate ligament reconstruction has a potential for graft contamination. The purpose of this study was to evaluate the possibility of contamination of the bone-patellar tendon-bone and hamstring tendon autograft during preparation for anterior cruciate ligament reconstruction. METHODS A primary isolated reconstruction of the anterior ...

BACKGROUND Anterior cruciate ligament reconstruction is commonly performed with autogenous hamstring tendon grafts. PURPOSE To ascertain the effects of braiding on ultimate tensile strength and stiffness of hamstring tendon graft. STUDY DESIGN Controlled laboratory study. METHODS Sixteen fresh-frozen semitendinosus and gracilis tendons were harvested from eight matched (right and left) hu...

Background Hamstring autograft size <8 mm has been shown to be a predictor for failure after anterior cruciate ligament (ACL) reconstruction. The ability to predict graft size preoperatively is helpful in counseling patients about the possible need for graft augmentation. Purpose To determine whether preoperative ultrasound (US) measurements of hamstring tendons can predict intraoperative gra...

  Background: Despite the importance of hamstring tendon autograft, one major disadvantage in applying this technique in the surgical reconstruction of anterior cruciate ligament is individual variability in the tendon diameter. Hence, the purpose of the present study was to use anthropometric parameters such as gender, height and body mass index to predict 4-strand (quadruple) hamstring ten...

The question of which graft to use for anterior cruciate ligament (ACL) reconstruction continues to be debated at meetings around the world. The overall choice of grafts consists of autografts, allografts, and synthetic grafts. By far the two most commonly used grafts are central third bone-patellar tendon-bone and hamstring tendon, either semitendinosus alone or semitendinosus combined with gr...

BACKGROUND The best choice of graft tissue for use in anterior cruciate ligament reconstruction has been the subject of debate. HYPOTHESIS Anterior cruciate ligament reconstruction with patellar tendon autograft leads to greater knee stability than reconstruction with hamstring tendon autograft. STUDY DESIGN Metaanalysis. METHODS A Medline search identified articles published from January...

Anterior cruciate ligament reconstruction is one of the most commonly performed procedures in orthopaedics, with more than 125,000 performed in the United States per year. There are several reconstruction graft choices that can be used to reconstruct the native anterior cruciate ligament, with autograft hamstring tendons being one of the most commonly used. Preparation of a hamstring autograft ...

+MacLeod, T D; Snyder-Mackler, L; Axe, M J; Buchanan, T S + Center for Biomedical Engineering Research, University of Delaware, DE [email protected] ABSTRACT INTRODUCTION: Anterior cruciate ligament (ACL) reconstruction is commonly performed with a cadaveric allograft (ALLO) or a hamstring semitendinosus-gracilis (STG) autograft. Knee flexor strength deficits following STG reconstruction are a g...

To evaluate whether pre-operative anthropometric data can predict the optimal diameter and length of hamstring tendon autograft for anterior cruciate ligament (ACL) reconstruction. This was a cohort study that involved 169 patients who underwent single-bundle ACL reconstruction (single surgeon) with 4-stranded MM Gracilis and MM Semi-Tendinosus autografts. Height, weight, body mass index (BMI),...

Hamstring autografts in anterior cruciate ligament reconstruction have an excellent clinical track record, but some patients have hamstring tendons that yield grafts of smaller diameter, which has been shown to be a significant risk factor for worse outcomes and graft failure. Some authors have advocated augmentation with allograft in these patients. Tripling the semitendinosus yields a complet...
