Active clinical trials for "Anterior Cruciate Ligament Injuries"

The natural course after ACL injury is not well described in the literature. Every year about 7000 people, a majority aged 15-30 years old, injure their anterior cruciate ligament (ACL) in Sweden. About 3500 go through surgical treatment and rehabilitation. Despite the large amount of research on ACL-injuries, there are still many patients who have unsatisfactory outcomes regarding instability, decreased activity level, and quality of life, not being able to return to sport as well as an increased risk for osteoarthritis. The general aim of the study is to evaluate the natural course and recovery after ACL injury. Specific aims: To evaluate physical, psychological and contextual factors affecting recovery after anterior cruciate ligament (ACL) injury. Recovery is related both to natural course and to treatment chosen To evaluate factors affecting the decision for which treatment to choose (ACL reconstruction and rehabilitation or rehabilitation alone) To evaluate factors affecting the decision for return to sports To study development of knee osteoarthritis after ACL-injury To study epidemiology of acute knee trauma To study risk factors for new injuries after ACL-injury These aims will be pursued by consequently and prospectively following patients who sustain a new ACL injury in a multicenter study including approximately 800 patients. Assessment methods will be questionnaires to patients, orthopedic doctors and physical therapists. A sub-cohort of 130 patients will undergo multiple clinical and functional examination as well as MRIs and blood, urine and joint fluid samples.

This case series evaluates whether patients with an anterior cruciate ligament (ACL) repair have better outcome if the anterolateral ligament (ALL) was repaired or not considering the ultrasound (US) pre-surgical recommendation.

The purpose of this study is to see if the study team can use micro-Doppler signal (MDS) technology to determine if someone has had an anterior cruciate ligament (ACL) reconstruction. The investigators will do this by comparing the movement data from a group of people who have had the surgery with a group who has not had the surgery to see if the micro-Doppler radar technology can accurately and predictably tell the difference.

Rationale: In anterior cruciate ligament (ACL) reconstruction, anatomical femoral tunnel positioning has proven to be difficult with current techniques. Limited visibility during surgery and high interpersonal variability are mainly responsible for non-anatomical femoral tunnel positioning. Non anatomical tunnel positioning can lead to long term failure of the reconstruction. In order to obtain an accurate and constant anatomical femoral tunnel position during ACL reconstruction, a patient specific surgical guide has been developed. Objective: to assess the accuracy of the newly developed patient specific femoral aimer used during ACL reconstruction. Study design: pilot study Study population: 10 subjects (>16 years of age ) with ACL injury, requiring ACL reconstruction. Intervention: all subjects will undergo ACL reconstruction in which a patient specific surgical guide is used for femoral tunnel positioning. Main study parameters/endpoints: the main study parameter is the difference between the planned femoral tunnel position and the achieved tunnel position. This difference is quantified in both mm (translation) and degrees (rotation). Nature and extent of the burden and risks associated with participation, benefit and group relatedness: No additional perioperative risks are associated with participation. Based on previous cadaver experiments, the accuracy of the patient specific, 3D printed femoral aimer is high. Subjects will undergo 1 postoperative MRI which will take place during a routine scheduled follow up visit.

The purpose of this study is to assess the intra-operative and post-operative effects of tourniquet use during ACL reconstruction. We hypothesize that: Limited tourniquet use will not significantly impact arthroscopic visualization nor the time it takes to complete an ACL reconstruction. Limited tourniquet use will lead to significantly less patient pain intra-operatively and in the immediate peri-operative period. Patients who undergo an ACL reconstruction with limited tourniquet use will have earlier return of quadriceps functions as compared to those undergoing reconstruction with the use of a tourniquet.

This is a prospective study comparing femoral nerve block plus sciatic nerve block to femoral nerve block plus infiltration of the posterior knee capsule (IPACK) in patients undergoing arthroscopic anterior cruciate ligament reconstruction. Femoral nerve block via the adductor canal (FNB-AC) with IPACK may provide effective analgesia while avoiding the motor block involved with sciatic nerve block. The lack of motor block is important to facilitate postoperative ambulation and physical therapy.

Anterior cruciate ligament repair using hamstring autograft in children is a painful orthopedic procedure. The current practice to provide analgesia for this procedure include femoral continuous perineural infusion and femoral single shot peripheral nerve block, along with perioperative opioids and NSAIDS both IV and orally. Since the use of opioids can be associated with adverse side effects, which include, but are not limited to nausea, vomiting, constipation, pruritus and respiratory depression, comparing the amount of opioid used with either analgesia delivery method is needed.

Injury to the knee during sports participation often involves partial or full detachment of the anterior cruciate ligament (abbreviated as ACL). ACL tears cause pain, swelling and inflammation. While the swelling and inflammation usually goes away in time, individuals with ACL injuries may experience pain and notice knee instability (knee slipping, etc.). Often surgery can repair or replace the ACL within the joint, allowing individuals the ability to walk or run again pain free or participate in sports. Unfortunately, osteoarthritis of the knee, which also causes pain and swelling, can occur in that same knee 10-20 years later for reasons which are not well understood. In this research study, the investigator hopes to reduce the initial pre-operative pain. The reduction of pain will allow for earlier movement of the knee joint and preparation for surgery. The investigator is interested to see if the use of Kineret does decrease the risk of developing arthritis in individuals with ACL injuries by treating them within 28 days after their injury.

The purpose of this study is to determine if extended-release triamcinolone acetonide treatment alters the progressive changes in bone shape previously demonstrated after anterior cruciate ligament (ACL) reconstruction with partial meniscectomy or meniscal repair.

This will be a randomized pilot study to determine the effectiveness of Personalized Blood Flow Restriction (PBFR) technique in conjunction with prescribed physical therapy (PT) in a cohort of anterior cruciate ligament (ACL) reconstruction subjects
