Active clinical trials for "Anterior Cruciate Ligament Injuries"

Primary objective of the study is to evaluate efficacy of the surgical technique for ACL reconstruction using an osteoconductive scaffold, enlaced into the hamstring tendon autograft, compared to the traditional technique.

The main goal of a rehabilitation program after an ACL reconstruction is to regain mobility and muscle function and ultimately to return to sports participation. Purpose of the study: to investigate the effect of the accelerated rehabilitation program on knee pain, and function in patients post ACLR surgery. Fifty adult amateur males athletes who underwent ACLR surgery participated in this study, their age ranged from 18 to 35years.They were randomly assigned into two equal groups. Group (A) received accelerated rehabilitation protocol and group (B) received conventional physical therapy program. Treatment sessions were conducted 5 times per week for 22 weeks for both groups. All patients assessed pre and post treatment for pain intensity using visual analogue scale (VAS), and knee function using knee injury and osteoarthritis outcome score (KOOS), knee effusion, and LSI of Hop test.

Returning to sport is one of the primary concerns of athletes following injury. Yet, after serious injury, up to 50% of athletes do not return to competitive sport. Psychological factors play an important role in the athlete's return to sport after anterior cruciate ligament (ACL) reconstruction, and physical and psychological readiness to return to sport often do not coincide. There are currently no easily accessible programs for non-professional athletes to help address the psychological factors that impact on their return to sport after injury. The aim of this trial is to test whether a smartphone application (app) delivering cognitive-behavioural therapy to address psychological factors including fear, confidence and recovery expectations, is effective for improving the number of people who return sport following ACL reconstruction. We hypothesise that patients who use the app in addition to receiving usual rehabilitation care after ACL reconstruction will return to sport in greater numbers than patients who receive usual rehabilitation care only.

The goal of this trial is to compare the efficacy of the Bridge-Enhanced Anterior Cruciate Ligament Repair (BEAR™) technique with the current method of treatment for anterior cruciate ligament (ACL) injuries, ACL reconstruction.

Bridge-Enhanced ACL Restoration (BEAR) is a new procedure being developed to treat patients with ACL injuries. In the BEAR procedure, an implant is placed between the torn ends of the ACL and the patient's own blood is added to the implant to stimulate ligament healing. We propose the current study to determine if older patients do better than younger patients (or vice versa) with this procedure. This is a cohort study designed to determine if age is a risk factor for a worse outcome after a bridge-enhanced ACL repair (BEAR) as defined by an 11.5 point difference on the IKDC Subjective or Objective Knee Evaluation score at two years after surgery. Additional objectives are to determine the effect of age on safety outcomes including infection, graft rejection, and need for further surgical procedures.

In Hong Kong, over 3000 Anterior Cruciate Ligament Reconstructions (ACLR) are performed each year in order to restore knee function after an ACL injury. The ultimate goal of ACLR is to fulfil the return-to-play (RTP) criteria. Despite successful surgery and a demanding rehabilitation process, some athletes still fail to comply to RTP. For those who achieve RTP, 23% of those who return to their sports would suffer a second ACL injury. Quadriceps muscle strength is one of the key determinants for a patient's successful return- to-play after ACLR. Quadriceps muscle atrophy can persist beyond the completion of the rehabilitation program in almost half the patients and the reason behind this is still unknown. Therefore, there is need to find a more effective way to increase quadriceps strength. There are emerging evidences showing that pulsed electromagnetic field (PEMF) can modulate mitochondrial activities for muscle gain. PEMF exposure on top of regular exercise training may promote muscle regeneration and tissue healing. This study aims to conduct a double-blinded, randomized controlled trial to investigate the effects of PEMF treatment during the late postoperative period on quadriceps muscle strength in ACL injured patient. Muscle endurance could only be investigated in late postoperative period. The investigators hypothesize that PEMF treatment is effective to reduce muscle weakness and promote gain in quadriceps muscle strength in ACLR patients. Based on the aim of this study, adult patients (aged 18-30) with a unilateral ACL injury, total quadriceps muscle volume is equal or morn than 7% deficit on involved leg compared with uninvolved leg, sporting injury with a Tegner score of 7+, both knees without a history of injury/prior surgery will be recruited. To estimate the improvement of patients, Isokinetic muscle assessment, ultrasound imaging and MRI for quadriceps muscle thickness, self-reported outcomes with questionnaires, KT-1000 for knee laxity and biomechanical analysis, Xtreme CT for Bone mineral density will be performed. To investigate the mechanism of PEMF therapy on increasing quadriceps strength, samples of blood serum will be draw before and after intervention.

A prospective study, with outcomes including re-rupture rate and return to sport will be collected following ACL reconstruction. In keeping with the surgeon's standard practice, patients 24 years and under that are skeletally mature, will receive a quad tendon autograft; patients 25 years of age and over will receive an allograft All-Inside ACL reconstruction. These two cohorts will then be randomized into two groups, one with bone marrow/DBM and InternalBrace augmentation, and one without. The study procedures will involve use of x-rays, MRI, CT scan, and surveys at varying time points to assess radiographic, imaging and clinical outcomes.

The objective of the study is to demonstrate the efficacy of the ultrasound-guided percutaneous neuromodulation technique in the femoral nerve in patients who underwent surgery for the anterior cruciate ligament.

The Thermo-LCA study is a diagnostic interventional study for assessment of knee temperature of asymptomatic patients with ACL reconstruction compared with unoperated healthy contralateral knee. The aim of the study is to analyze thermographic images obtained from the knees of asymptomatic patients with ACL reconstruction that occurred between the previous 2 and 5 years, to assess the presence of inflammation in the knee with reconstructed ACL compared with the contralateral.

The study is intended to include all patients who will undergo surgical reconstruction of the anterior cruciate ligament (ACL). The patients will be monitored and evaluated preoperatively and also at 6 months and 1 years after the intervention through a clinical visit. Such assessments will include the patient reported outcomes, the objective examination of the knee during a medical examination to quantify its stability and the radiological examination.
