Outcome Measures

Primary Outcomes (2)

  • International Knee Documentation Committee (IKDC) Subjective Knee Evaluation score at year 2

    This is a survey patients complete about how their knee is feeling and functioning. Range is 0 to 100, with 100 indicating no problems and 0 indicating extreme problems.

    2 Years

  • Knee laxity based on the Lachman test at 1 year

    The Lachman will be performed during physical exam.

    1 year

Secondary Outcomes (7)

  • IKDC Subjective Knee Evaluation Score and Physical Exam at 6, 9 and 12 months post-surgery and according to standard of care

    6-12 months

  • Knee Injury and Osteoarthritis Outcome Score (KOOS) domains: Symptoms/Stiffness, Pain, Knee Related Quality of Life, and Knee Related Sports/Recreational Activities starting at 6, 9, 12 months and at 2 years after surgery

    6 months- 2 years post surgery

  • Marx Activity Score at 6, 9, 12 months and at 2 years after surgery

    6 months thru 2 years

  • Return to Sports Index (RSI) at 6, 9, 12 months and at 2 years after surgery

    6 months thru 2 years

  • VAS (Visual Analog Scale) Pain Score from post op through the first 12 months (approximately every 12 weeks) and at 2 years after surgery

    1 year

  • +2 more secondary outcomes

Study Arms (2)

Prospective Cohort

There will be a prospective cohort for all subjects scheduled to undergo ACL surgery with the BEAR Implant that are willing to provide consent.

Device: The BEAR® Implant

Retrospective Cohort

A retrospective cohort will be available for all subjects treated with the BEAR Implant at each participating site. There is no control group.

Device: The BEAR® Implant

Interventions

The BEAR Implant is a bovine collagen-based implant. The bovine tissue is sourced from countries that are free of bovine spongiform encephalopathy \[BSE\] and is further treated to remove bovine cell fragments and DNA. The BEAR® (Bridge Enhanced ACL Restoration) Implant is a bovine extracellular matrix collagen-based implant for treatment of anterior cruciate ligament (ACL) injuries. The BEAR® Implant is indicated for skeletally mature subjects at least 14 years of age with a complete rupture of the ACL. Subjects must have an ACL stump attached to the tibia to construct the repair.
