Trial Summary

What is the purpose of this trial?This trial is testing BEAR, a new knee surgery method using a sponge to help a torn ligament heal. It targets patients aged 18-55 who need ACL surgery. The sponge helps the torn ligament ends grow back together naturally. BEAR has shown promising results in early studies, suggesting it may be a viable alternative to traditional ACL reconstruction methods.
Will I have to stop taking my current medications?

The trial protocol does not specify whether you need to stop taking your current medications. However, if you are using corticosteroids or have been treated with intra-articular corticosteroids in the affected knee within the last 6 months, you may not be eligible to participate.

What data supports the effectiveness of the treatment BEAR Device vs. Autograft for ACL Tear?

Research shows that using a bone-patellar tendon-bone (BPTB) autograft for ACL reconstruction is considered a reliable method with good long-term success rates. This technique is known for its strong graft fixation and early bone healing, which are important for effective ACL repair.

Is the BEAR Device vs. Autograft for ACL Tear safe for humans?

The studies reviewed focus on the safety and effectiveness of bone-patellar tendon-bone (BPTB) autografts for ACL reconstruction, which is a common and generally safe procedure for repairing ACL tears. However, specific safety data for the BEAR device is not provided in these studies.

What makes the BEAR Device treatment for ACL tears unique compared to other treatments?

The BEAR Device treatment for ACL tears is unique because it uses a special implant to encourage the body to heal the torn ligament naturally, rather than replacing it with a graft from another part of the body, which is common in traditional ACL reconstruction methods.

Participant Groups

The study compares two surgical techniques for repairing torn ACLs: the new BEAR method using a blood-enriched implant to promote healing, versus the traditional BPTB reconstruction that uses transplanted patellar tendon tissue.
2Treatment groups
Experimental Treatment
Active Control
Group I: Bridge Enhanced ACL RestorationExperimental Treatment1 Intervention
Procedure/Surgery Bridge Enhanced ACL Restoration (BEAR): The surgical repair of the ACL using the BEAR technique involves surgically placing a sponge (the BEAR implant) between the torn ends of the ACL, providing a sponge for the ligament ends to group into.
Group II: ACL Reconstruction(BPTB Graft)Active Control1 Intervention
Procedure/Surgery ACL Reconstruction (Bone Patellar Tendon Bone Graft): Standard of care surgical procedure Patellar Tendon Autograft ACL reconstruction, in which a bone-patellar tendon-bone graft from the front of the knee is taken to replace the torn ACL.

Combined press-fit and extracortical fixation in patellar tendon anterior cruciate ligament reconstruction results in reliable graft fixation and early bone block incorporation. [2023]Anterior cruciate ligament (ACL) reconstruction with bone-patellar-tendon-bone (BPTB) autograft has the potential biological advantage of direct bone-to-bone healing over soft tissue grafts. The primary aim of this study was to investigate possible graft slippage and therefore fixation strength in a modified BPTB autograft technique with suspensory fixation on both sides for primary ACL reconstruction until bony integration takes place.

To study the incidence of heterotopic ossification after anterior cruciate ligament reconstruction. [2021]Previous studies have enumerated the advantages of an arthroscopic Anterior Cruciate Ligament (ACL) reconstruction with the use of a Bone Patellar Tendon Bone (BPTB) graft. Complications are extremely rare in such surgeries and one such known complication, which is an extra-articular heterotophic ossification at the femoral tunnel site, is rarely seen only in few patients.
A meta-analysis of patellar tendon autograft versus patellar tendon allograft in anterior cruciate ligament reconstruction. [2022]Studies have suggested good long-term success rates with bone-patellar tendon-bone (BPTB) autograft and BPTB allograft in anterior cruciate ligament (ACL) reconstruction, but the numbers reported in available prospective studies may be underpowered to elucidate significant differences between the two groups. Here, we present a meta-analysis to compare the results of BPTB autograft and BPTB allograft in primary ACL reconstruction.

[2022]To the best of our knowledge, there has been no detailed study on bone-patellar tendon-bone (BTB) grafts for remnant-preserving, selective-bundle anterior cruciate ligament (ACL) augmentation. Therefore, we aimed to develop such a technique using a BTB graft.

[2022]The most frequently used auto-grafts for ACL reconstruction (ACLR) are bone-patellar tendon-bone (BPTB) and four-strand hamstring tendon (4S-HT), but significant controversy exists about which graft is better. This study aimed to compare the knee outcomes following ACLR with BPTB and 4S-HT autografts.

Return to Baseline Physical Activity After Bone-Patellar Tendon-Bone Versus Hamstring Tendon Autografts for Anterior Cruciate Ligament Reconstruction: A Systematic Review and Meta-analysis of Randomized Controlled Trials. [2022]Bone-patellar tendon-bone (BPTB) and hamstring tendon (HT) autografts are the most utilized grafts for primary anterior cruciate ligament (ACL) reconstruction. The ability of a patient to return to a preinjury level of physical activity is a key consideration in choice of graft; the influence of graft choice on this metric lacks consensus in the literature.
