Abstract

Background:

Hamstring tendons are widely used in anterior cruciate ligament reconstruction. Improvements in fixation materials have increased the success of the reconstruction procedures using this type of graft. The main advantage of the hamstring tendon autograft is the lower donor site morbidity associated with its harvesting. On the other hand, tunnel widening is reported more frequently with the use of hamstring tendon autograft compared to patellar or quadriceps tendons. The objective of the present study was to evaluate three different fixation techniques at a minimum of 2 years after Anterior Cruciate Ligament (ACL) reconstruction using gracilis and semitendinosus autograft.

Methods:

Between February 2012 and March 2016, 112 ACL reconstructions using double looped semitendinosus and gracilis graft were performed. Patients were divided into 3 groups in a randomized fashion. 98 patients were followed up for 2 years. In the first group (43 patients), suspensory fixation using Retrobutton (Arthrex, Inc, Naples, Florida) was used. In the second group (30 patients), transcondylar graft fixation Bio-Transfix (Arthrex, Naples, Florida) was performed, and in the third group (25 patients), aperture fixation using AperFix (Cayenne Medical, Scottdale, Arizona, Biomet) was performed. Clinical evaluation was performed using the International Knee Documentation Committee (IKDC) form, Lysholm knee and Tegner activity level scores, as well as arthometer measurements. Tunnel enlargement and graft integrity were evaluated using Magnetic Resonance Imaging (MRI) at 6, 12 and 24 months.

Results:

Ten patients were completely lost to follow up, and four had undergone a revision ACL reconstruction before the two-year follow up period, leaving 98 patients for analysis. No statistically significant differences between the three groups were noted other than that the first group tended to have more tunnel enlargement than the other two groups, especially at the femoral tunnel (p=.026), but not at the tibial tunnel (p>0.408). Our results showed that almost 90% of the patients in the three groups had functionally normal or near normal IKDC, Lysholm and Tegner scores.

Conclusion:

The three different techniques yielded equal results as regards improved patient performance. The functional results as well as knee stability tests were not related with tunnel enlargement, at least in the short term.

"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."


Jacques Descotes
(Centre Antipoison-Centre de Pharmacovigilance, France)

"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."


Patrice Talaga
(UCB S.A., Belgium)

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."


Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."


Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."


Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."


Richard Reithinger
(Westat, USA)

"Not only do open access journals greatly improve the access to high quality information for scientists in the developing world, it also provides extra exposure for our papers."

"Open Access 'Chemistry' Journals allow the dissemination of knowledge at your finger tips without paying for the scientific content."


Sean L. Kitson
(Almac Sciences, Northern Ireland)

"In principle, all scientific journals should have open access, as should be science itself. Open access journals are very helpful for students, researchers and the general public including people from institutions which do not have library or cannot afford to subscribe scientific journals. The articles are high standard and cover a wide area."
