Active clinical trials for "Anterior Cruciate Ligament Injuries"

This is a multicenter randomized, placebo-controlled trial to assess whether a 6-month course of oral montelukast after ACL reconstruction reduces systemic markers of inflammation and biochemical and imaging biomarkers of cartilage degradation. This study will specifically target older ACL reconstruction patients with concomitant meniscal injuries as this group is at greatest risk of rapid PTOA progression. Patients will randomly be assigned to receive oral montelukast (10 mg) versus placebo daily for 6 months after surgery.

This is a study comparing the effects of blood flow restriction (BFR) therapy on the maturation of the Anterior Cruciate Ligament (ACL) graft after reconstruction surgery compared to physical therapy without the use of BFR.

The study aims to examine the effect of short-term rehabilitation exercise support using digital healthcare system (Uincare homeplus) in the patients with anterior cruciate ligament reconstruction. The study is a two-arm prospective randomized controlled study comparing the effect of rehabilitation exercise digital healthcare system at home with conventional brochure-based home exercise. Limb Symmetry Index (LSI), Pain (using Numerical rating scale), knee joint range of motion (ROM), lower extremities motor power (using Manual muscle test), International Knee Documentation Committee (IKDC) and quality of life using EQ-5D-5L will be evaluation on enrollment, 2-weeks, 6-weeks, 12-weeks and 24-weeks after enrollment.

Randomized control trial comparing two different Anterior Cruciate Ligament (ACL) grafts in Anterior Cruciate Ligament Reconstruction: the semitendinosus hamstrings graft and the quadriceps graft. Capio Artro Clinic (Stockholm) has vast experience in ACL surgery using both semitendinosus and quadriceps grafts.

The goal of this randomized clinical trial is to evaluate the effects of vibration on factors related to the risks of post-traumatic knee osteoarthritis and secondary anterior cruciate ligament (ACL) injury in individuals who have undergone anterior cruciate ligament reconstruction surgery (ACLR). The main objectives are to compare the effects of Standard rehabilitation vs. rehabilitation that includes whole body vibration (WBV) or local muscle vibration (LMV) on: Quadriceps muscle function Gait biomechanics linked to post-traumatic knee osteoarthritis development Patient self-report outcomes MRI indicators of knee joint health Landing biomechanics linked to secondary ACL injury risk Evidence-based return-to-physical-activity criteria Participants will be assigned to 1 of 3 groups (standard rehabilitation, standard rehabilitation + WBV, or standard rehabilitation + LMV) and will complete assessments of quadriceps function, gait biomechanics, landing biomechanics, functional ability, patient-report outcomes, and MRI 1, 6, and 12 months after ACLR. Researchers will compare the groups to see if vibration embedded in ACLR rehabilitation improves joint health outcomes.

The project is a pragmatic registry-based RCT aiming to investigate ACL injury treatment. Study results will help fill knowledge gaps, facilitate shared decision making and strengthen patient treatment. Included patients will be randomized to (1) early ACL surgery followed by rehabilitation or (2) active rehabilitation with optional delayed surgery if indicated. Randomization and data collection is conducted through the Norwegian National Knee Ligament Registry (NNKLR) which is a well established population based ACL registry. Participation is based on informed consent to participate in the NNKLR and the registry-based RCT. The study uses the platform and outcome measures of the NNKLR to collect and measure data. The data will be stored as usual in the NNKLR, but RCT specific data will be exported for analysis and stored inTjenester for sensitive data (TSD). Data collected in NNKLR are: patient data (age, height, weight, activity level, smoking-and snuff habits), knee injury data (injury data, injury mechanism, additional knee injury), treatment (non-operative or ACL reconstruction, reoperation), surgical details (operation date, antibiotics, anti-coagulants, graft type and size, approach for femoral tunnel, additional injury and additional surgical procedure) and patient reported knee function at baseline, 2, 5 and 10 years. Also, x-rays and MRIs will be imported for included patients and stored in TSD.

After rehabilitation completion, there remains large deficiencies between the operative (OP) and non-operative (NOP) limbs in lower-limb outcomes (e.g., size, strength, and function) and these deficits can persist for years. Therefore, further specialized training protocols, such as the ones in the present study, are required to determine if these deficits can be lessened. The proposed project will evaluate the effect of 8-weeks of single-leg and double-leg lower-body resistance training on musculoskeletal function in individuals with a previous anterior cruciate ligament (ACL) reconstruction (ACLR) in a randomized control trial. The study will recruit 30-40 males and females between 18-35 years of age that have undergone a previous ACLR. Participants will be randomized to either the single-leg/unilateral (UL) or double-leg/bilateral (BL) training groups. Training will occur three times per week for 8-weeks. The UL group will participate in exercises such as split squats, single-leg deadlifts, or single-leg squats. The BL group will utilize exercises such as double-leg squats, conventional deadlifts, and leg presses. One week prior to (PRE) and one week after (POST) the training program, all participants will undergo a testing battery. Musculoskeletal ultrasound will measure quadriceps and hamstrings muscle cross-sectional area (mCSA), fascicle length (FL), and pennation angle (PA) of both OP and NOP limbs. Strength will be assessed through maximal voluntary isometric contractions (MVIC) for the quadriceps and hamstrings, and one-repetition maximum tests for single-leg leg extensions, leg curls, and leg press. Lower-limb function will be assessed through single-leg and double-leg jumps on a dual force plate system for jump height, impulse, rate of force development, and peak force. Data will be analyzed via separate mixed-factorial analyses of variance for the within-subjects factor of leg (OP vs. NOP) and time (PRE vs. POST) and the between-subjects factor of biological sex (male vs. female) and group (UL vs. BL). Post-hoc analyses will include lower-order ANOVAs and t-tests as pairwise comparisons when significance is detected. Significance will be established at p≤0.05. The results of this study will assist practitioners, coaches, sport scientists, and most importantly, the athletes, in the development of post-rehabilitative strength training protocols designed to reduce between-limb discrepancies.

A randomised prospective control trial comparing the efficiency of a more individualized approach in ACL reconstruction with the help of neuromuscular computer models with traditional ACL reconstruction practices.

Anterior cruciate ligament (ACL) rupture is one of the most common musculoskeletal injuries in young individuals, particularly those that are active in sports. Up to 30% of individuals under the age of 20 years suffer a re-injury to the reconstructed ACL. Revision ACLR has been associated with degeneration of the articular cartilage and increased rates of meniscal tears, increasing the risk of post-traumatic osteoarthritis (PTOA), additional surgical procedures, reduced physical function and quality of life. As such, strategies to reduce ACLR failure, particularly in young active individuals, are critical to improving short and long-term outcomes after ACL rupture. There is ongoing debate about the optimal graft choice and reconstructive technique. Three autograft options are commonly used, including the bone-patellar-tendon-bone (BPTB), quadriceps tendon (QT) and hamstring tendon (HT). Additionally, a lateral extra-articular tenodesis (LET) may provide greater stability to the ACLR; however, its effect on failure rate is unclear and surgery-induced lateral compartment OA is a concern. To definitively inform the choice of autograft and the need for a LET, this multicenter, international randomized clinical trial will randomly assign 1236 young, active patients at high risk of re-injury to undergo ACLR using BPTB or QT autograft with our without LET.

This study is designed to evaluate bridge-enhanced ACL restoration (BEAR), a new surgical technique for repairing knees injured by a tear of the anterior cruciate ligament (ACL) that promotes reattachment and healing of the ACL using a blood-enriched implant. BEAR will be compared to bone to patellar tendon to bone autograft (BPTB) reconstruction, a standard ACL surgical reconstruction technique that replaces a torn portion of the ACL with transplanted patellar tendon tissue, and thus requires additional invasive patellar tendon removal and reuse as a portion of the ACL surgery, in a two group randomized clinical trial (RCT) in which participants will have equal chance of receiving BEAR or BPTB reconstruction. The BEAR technique is FDA approved and involves surgically placing a sponge (the BEAR implant) between the torn ends of the ACL, providing an absorbable implant for the ligament ends to grow into. The investigators hypothesize that the ACL repair with BEAR technology will achieve results not appreciably worse than BPTB reconstruction, with a reduced burden of invasive surgery, when assessed over the first two post-operative years. Animal studies suggest BEAR may also ameliorate longer-term premature osteoarthritis of the knee, a common consequence of ACL reconstruction surgery. However, no human data yet support that, and this trial will conclude before such a benefit can be observed. All patients 18-55 years of age who are candidates for ACL surgery within 50 days of the ACL injury and who present to surgeons participating in the study will be offered participation in the trial. Patients will be randomized and will undergo specified rehabilitation protocols post-operatively with primary assessments of knee laxity and patient reported measures at 6 months, 1 year, and 2 years.
