PURPOSE The aim of the present study was to compare primary stability in ACL reconstruction and ultimate load to failure of a mesh augmented hamstring tendon graft fixed with two cross pins to established hamstrings and bone-patellar-tendon-bone (BTB) graft fixation methods. METHODS Forty fresh porcine femora were divided into four groups: (A): BTB graft fixed with two RigidFix® pins, (B): ha...

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 tendons (...

BACKGROUND Bone-patellar tendon-bone (bone-tendon-bone) and four-strand hamstring tendon grafts (hamstring) are the most commonly utilized autografts for primary anterior cruciate ligament (ACL) reconstruction. Existing clinical trials, registry studies, and meta-analyses offer conflicting opinions regarding the most favorable graft choice. QUESTIONS/PURPOSES Which graft type for ACL reconstr...

Background Involvement of the intramuscular (central) tendon in acute hamstring injuries, as detected on magnetic resonance imaging (MRI), may prolong recovery times. To date, it is unclear whether hamstring injuries exhibiting intramuscular tendon involvement can be identified though routine clinical examinations that assess flexibility and strength. Purpose To test whether MRI-detected intr...

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 As compared with injuries involving muscle only, those involving the central hamstring tendon have a worse prognosis. Limited information is available regarding the surgical treatment of central tendon injuries of the hamstrings. Purpose To describe the operative treatment and outcomes of central tendon injuries of the hamstrings among athletes. Study Design Case series; Level of...

Background This study aimed to compare stability, functional outcome, and second-look arthroscopic findings after anterior cruciate ligament reconstruction between remnant-preserving tibialis tendon allograft and remnant-sacrificing hamstring tendon autograft. Methods We matched two groups (remnant-preserving tibialis tendon allograft group and hamstring tendon autograft group) in terms of de...

PURPOSE To report outcomes of revision anterior cruciate ligament (ACL) reconstruction using tibial or hamstring tendon allografts and to compare with another study using non-irradiated fresh-frozen bone-patellar tendon-bone allografts. METHODS Records of 12 men and 7 women aged 18 to 53 (mean, 33) years who underwent revision ACL reconstructions using tibial tendon (n=17) or hamstring tendon...

BACKGROUND Patellar and hamstring tendon autografts are the most frequently used graft types for anterior cruciate ligament reconstruction, but few direct comparisons of outcomes have been published. HYPOTHESIS There is no difference in outcome between the two types of reconstruction. STUDY DESIGN Prospective randomized clinical trial. METHODS After isolated anterior cruciate ligament rup...

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 ...
