NCT05494073

Brief Summary

Patients between 14-60 years of age who will undergo an anterior cruciate ligament (ACL) reconstruction between Nov 1, 2021- Dec 31, 2023, will have their charts reviewed be approached in clinic when the surgery is scheduled regarding their participation in this study. At the time of consent, patients will be randomized to a group via a computerized randomization process, either the experimental hybrid remnant repair (HRR) or traditional ACL reconstruction with ACL stump debridement. Routine postoperative data will be collected at regularly scheduled post-operative and physical therapy appointments including range of motion, pain, patient-reported outcomes, return-to-sport tests, and proprioceptive data. Additionally, patients will be asked to undergo a post-operative MRI between 9 and 15 months following the date of their surgery. Radiologists reading the MRIs will be blinded to which group the patient is in. The primary outcome measure is graft incorporation between the two groups.

Outcome Measures

Primary Outcomes (1)

  • Post-operative imaging (MRI) graft incorporation

    We hypothesize patients undergoing HRR ACLR will have better incorporation with improved vascularity compared to patients undergoing a traditional ACLR. We hypothesize that this will lead to improved proprioceptive abilities and improved patient reported outcomes, which may reduce the time required to be cleared to return-to-sport and resume usual activities of daily living.

    1 year post ACLR

Secondary Outcomes (5)

  • Subject proprioceptive ability

    Collected at intervals during post-operative period once cleared by physician and physical therapy. 6 weeks, 3 months, 6 months, 12 months since post operative date.

  • Subject quadriceps strength

    Collected pre-operatively and at intervals during post-operative period once cleared by physician and physical therapy.6 weeks, 3 months, 6 months, 12 months since post operative date.

  • Patient-reported outcomes (PROMIS forms)

    Collected pre-operatively and at intervals during post-operative clinic visits. 6 weeks, 3 months, 6 months, 12 months since post operative date.

  • Subject range-of-motion

    Collected pre-operatively and at intervals during post-operative clinic visits. 6 weeks, 3 months, 6 months, 12 months since post operative date.

  • Return-to-sport (time from surgery)

    Variable depending on patients individual recovery. 6 weeks, 3 months, 6 months, 12 months since post operative date.

Study Arms (2)

Hybrid Remnant Repair

EXPERIMENTAL

Patients in this arm will have an ACL reconstruction with preservation and incorporation of the the ACL remnant.

Procedure: ACL Reconstruction with Hybrid Remnant Repair

Control

ACTIVE COMPARATOR

Patients in this arm will have a ACL reconstruction where the ACL remnant is not incorporated into the graft.

Procedure: ACL Reconstruction without Hybrid Remnant Repair

Interventions

The intervention includes the incorporation of the host ACL remnant into the graft. The intervention hopefully
