BACKGROUND: This study assessed the safety of the newly developed bridge-enhanced anterior cruciate ligament (ACL) repair (BEAR), which involves suture repair of the ligament combined with a bioactive scaffold to bridge the gap between the torn ligament ends. As the intra-articular environment is complex in its response to implanted materials, this study was designed to determine whether there would be a significant rate of adverse reaction to the implanted scaffold. HYPOTHESIS: The primary hypothesis was that the implanted scaffold would not result in a deep joint infection (arthrocentesis with positive culture) or significant inflammation (clinical symptoms justifying arthrocentesis but negative culture)...

BACKGROUND: Ulnar collateral ligament reconstruction (UCLR) has become a common procedure performed in overhead-throwing athletes of many athletic levels. PURPOSE/HYPOTHESIS: The purpose of this study was to determine whether clinical outcomes and return-to-sport (RTS) rates differ among patients undergoing UCLR based on graft choice, surgical technique, athletic competition level, handedness, and treatment of the ulnar nerve. We hypothesized that no differences would exist in clinical outcomes or RTS rates between technique, graft choice, or other variables...

BACKGROUND: Few studies have compared clinical and radiological outcomes after hamstring anterior cruciate ligament (ACL) reconstruction with fixed-loop and adjustable-loop cortical suspension devices. PURPOSE/HYPOTHESIS: The purpose of this retrospective study was to compare clinical outcomes and tunnel widening after hamstring ACL reconstructions with fixed- and adjustable-loop cortical suspension devices. The hypothesis was that compared with femoral graft fixation with the fixed-loop device, fixation with the adjustable-loop device would show similar clinical outcomes and would result in less tunnel widening after hamstring ACL reconstruction...

BACKGROUND: Conduct a prospective randomized study to compare clinical outcomes of anterior cruciate ligament (ACL) reconstruction using quadrupled hamstring tendon (HT) allograft or doubled tibialis anterior (TA) allograft. Limited level 1 data exist comparing outcomes of different soft tissue allograft constructs for ACL reconstruction. We hypothesized no difference would exist in the patient reported outcomes (PRO), arthrometric testing, or rate of re-rupture between the two constructs...

INTRODUCTION: Chronic ACL insufficiency with associated varus malalignment due to knee osteoarthritis (OA) is challenging to treat surgically. A combined ACL reconstruction (ACLR) with medial open wedge high tibial osteotomy (HTO) without using any metallic implant for HTO is an effective technique. MATERIALS AND METHOD: All the patients attending the outpatient department ACL injury and with associated medial compartment OA (Kellegren's grade 2 and grade 3) were considered for inclusion in the study...

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 (gracilis and 2-strand semitendinosus tendons). METHODS: This is a cross-sectional study conducted on all consecutive patients who underwent arthroscopic ACL reconstruction between 2013 and 2015...

In a Level III, single center, retrospective, nonrandomized observational study, anterior cruciate ligament reconstruction revision rates and patient-reported outcomes were found to be similar at 2-year follow-up when using autograft hamstrings versus a hybrid graft (autograft and nonirradiated allograft), with both groups reporting low levels of revisions and excellent outcomes. Despite previous published data that were cause for concern, a study in this issue provides support for use of a hybrid graft technique when encountering the challenging situation of a diminutive hamstring autograft when performing anterior cruciate ligament reconstruction...

Nowadays, bone tunnel enlargement (BTE) after anterior cruciate ligament reconstruction is a well-known phenomenon. It has been identified, investigated and described by many authors during the last thirty years. Nevertheless, the etiology of bone tunnel enlargement still remains unclear. It is known that the causes are multifactorial and may include the surgical technique, the method of fixation, materials used, type of graft as well as biological factors. Due to the recent popularization of the use of hamstring grafts in anterior cruciate ligament reconstruction, the bone tunnel enlargement phenomenon is becoming increasingly common...

The incidence of anterior cruciate ligament (ACL) injuries is rising every year. The autologous hamstring tendon graft, using semitendinosus tendon (SMT) and gracilis tendon (GR), is a common repair technique in the management of ACL injuries due to its multiple advantages. Using a final graft with a minimum diameter of 8 mm is necessary to avoid graft failure. The aim of this study was to find a correlation between preoperative ultrasound (USG) measurement of the SMT and GR tendon diameters (SMTd and GRd) and their actual diameters measured during the grafting procedure...

OBJECTIVE: To assess the effects of adding a whole-body vibration protocol at optimal frequency (WBV-OF) to a traditional rehabilitation programme (TRP) early after anterior cruciate ligament reconstruction, on maximal strength and balance, in comparison with a traditional rehabilitation programme. DESIGN: A total of 34 anterior cruciate ligament reconstructed patients with hamstring-tendon graft underwent either 4 weeks of WBV-OF training in addition to a traditional rehabilitation programme, or a traditional rehabilitation programme only, starting from the first month after surgery...

INTRODUCTION: Femoral nerve block (FNB) is considered as a major advance in anterior cruciate ligament (ACL) reconstruction as it reduces the need for parenteral opioids. However, the incidence of transient or even permanent neurological deficits due to the FNB is estimated at 1.94% after knee surgery. The primary objective of this study was to compare local infiltration analgesia (LIA) to FNB during ACL reconstruction procedures. The study hypothesis was that LIA was not less effective than FNB on early postoperative pain...

PURPOSE: Precise pre-tensioning protocol of the graft has not been determined in anterior cruciate ligament (ACL) reconstruction. The aims of this study are to measure the human autologous graft elongation, and to reveal what portion of the graft elongated greater after pre-tensioning in ACL reconstruction. METHODS: Twenty-four hamstring tendon grafts which were harvested from patients were included. A continuous load of 150 N was applied to the graft twice for 30 seconds each (150 N-1 minute), and the same loading was repeatedly applied (150 N-2 minute)...

BACKGROUND: This paper reports the outcomes of patients undergoing ACL reconstruction using a TransLateral single bundle, all-inside hamstring technique at a minimum of two year follow-up. METHODS: The semitendinosus alone is harvested, quadrupled and attached in series to two adjustable suspensory fixation devices. Femoral and tibial sockets are produced using a retrograde drill. The graft is deployed, fixed and tensioned on both tibia and femur. Patients were evaluated preoperatively using the KOOS, Lysholm and Tegner scores and at six, 12 and 24months postoperatively...

INTRODUCTION: The main objective of this multicenter study was to assess the feasibility of ambulatory surgery in France in anterior cruciate ligament (ACL) reconstructions for any technique or graft used (hamstring, patellar tendon, fascia lata). We hypothesized that a dedicated organization would guarantee the patient's safety. PATIENTS AND METHODS: A multicenter, non-randomized, prospective, comparative study, conducted within the SFA symposium was conducted between January 2014 and March 2015, included all the patients operated on for arthroscopic ACL reconstruction using different surgical techniques...

OBJECTIVE: The goal of this study was to assess ACL grafts compliance (equal inverse of stiffness) after surgery (D-1, 30, 90, 180, 1Y). MATERIAL/PATIENTS AND METHODS: Fifty-three patients (15F, 38M) were tested with GNRB laximeter (Genourob company, France) during 1 year. We analysed the slope of the curves during the first year of ligamentisation (It's a more objective parameter than just the laxity at one force): operated side/healthy side (O/H). It was the same surgeon and the same surgery (hamstrings tendon transplant) for all patients...

BACKGROUND: Recommendations for bone tunnel placement during anterior cruciate ligament (ACL) reconstruction have become more precise. However, these recommendations differ neither with the choice of graft nor with the method of fixation used. The influence of the method of femoral fixation used on the biomechanical function of a soft tissue ACL graft remains unknown. HYPOTHESIS: Our null hypothesis was that adding femoral aperture fixation to femoral cortical fixation, using the same bone tunnels, will not alter the control of anterior translation (AT) and internal rotation (IR) during ACL reconstruction using a hamstring graft...

INTRODUCTION: For successful anterior cruciate ligament (ACL) reconstruction, revascularisation and histological maturation are necessary, as their failure can cause graft rupture. PURPOSE: The purpose of this study was to describe differences in the histological maturation of early failed plasty (less than 12 months after surgery) and late failed plasty (more than 12 months after surgery) in patients with re-rupture after ACL reconstruction with hamstring tendons...

PURPOSE: In order to minimize viscoelastic elongation of ACL reconstruction grafts, preconditioning protocols have been employed in clinical practice prior to final graft fixation. The purpose of this study was to evaluate two separate high-load static preconditioning protocols of double-looped semitendinosus-gracilis grafts and compare these results to both a current clinical protocol and a control group with no preconditioning protocol applied. It was hypothesized that a high-load, static preconditioning protocol would minimize graft elongation during a simulated progressive early rehabilitation compared to both the "89 N" clinical protocol and control groups...
