What this trial studies

This research investigates the effectiveness of Blood Flow Restriction (BFR) therapy combined with standard rehabilitation for patients recovering from anterior cruciate ligament reconstruction (ACLR) using quadriceps tendon autograft. The study involves a prospective, randomized controlled trial where patients will be assigned to either a standard rehabilitation program or a program that includes BFR therapy. MRI scans will be conducted to assess quadriceps muscle cross-sectional area and strength at various intervals post-surgery, alongside patient-reported outcomes to evaluate functional improvement. The goal is to determine if BFR therapy can enhance recovery and return-to-duty times for active duty military personnel.

Who should consider this trial

Good fit: Ideal candidates are active duty military members aged 15 to 45 who require ACL reconstruction with quadriceps tendon autograft.

Not a fit: Patients with concurrent knee surgeries or those unable to adhere to rehabilitation protocols may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve recovery times and functional outcomes for patients undergoing ACL reconstruction.

How similar studies have performed: Previous studies have shown promising results with BFR therapy in rehabilitation settings, suggesting potential for success in this approach.

Eligibility criteria

Inclusion Criteria:

* Active duty member or Department of Defense Military Health System beneficiary
* 15 to 45 years of age
* Indicated for ACL reconstruction with quadriceps tendon autograft with evidence of skeletal maturity; no open physes/growth plates

Exclusion Criteria:

* Patients undergoing a concomitant surgical procedure that would otherwise require a period of immobilization and/or restricted weight bearing (i.e. meniscal repair, meniscal allograft transplantation, osteochondral allograft transplantation, high tibial osteotomy) will be excluded.
* Undergoing combined multiligamentous knee injury reconstruction
* Unable to consistently participate in the prescribed post-operative rehabilitation regimen
* No patients with a history of recent lower extremity deep vein thrombosis, within the 12 months or on active treatment with anticoagulants, a history of ipsilateral lower extremity lymph node dissection or a history of endothelial dysfunction.
* Patients that are unable to obtain MRI secondary to either intolerance and/or implanted medical devices that preclude the safe completion of the MRI.
