Brief summary

The purpose of the Bridge Registry is to assess real-world performance of the FDA approved BEAR Implant.

Detailed description

This is an observational study, where the BEAR Implant will be evaluated in a real-world setting. The registry seeks to enroll consecutive uses of the BEAR Implant at participating sites. There will be a prospective cohort for all subjects scheduled to undergo ACL surgery with the BEAR Implant that are willing to provide consent. A retrospective cohort will be available for all subjects treated with a BEAR Implant at each participating site. There is no control group.

Interventions

DEVICEThe BEAR® Implant

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.

Design outcomes

Primary

MeasureTime frameDescription
International Knee Documentation Committee (IKDC) Subjective Knee Evaluation score at year 22 YearsThis 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.
Knee laxity based on the Lachman test at 1 year1 yearThe Lachman will be performed during physical exam.

Secondary

MeasureTime frameDescription
IKDC Subjective Knee Evaluation Score and Physical Exam at 6, 9 and 12 months post-surgery and according to standard of care6-12 monthsThis is an examination performed of the knee. Scores are one of four measures: A (Normal), B (Nearly Normal), C (Abnormal) and D (Severely Abnormal). A is the best outcome and D is the worst.
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 surgery6 months- 2 years post surgeryThis is a survey with 5 subscales (Pain, Symptoms, Function in Daily Living, Function in Sport and Recreation, and Knee Related Quality of Life). The range of each subscale is 0 to 100, with 100 indicating no problems and 0 indicating extreme problems. The subscales are reported individually and not combined.
Marx Activity Score at 6, 9, 12 months and at 2 years after surgery6 months thru 2 yearsPatients are asked to indicate approximately how many times in the past 12 months they performed each of these activities while at their healthiest and most active state. The four knee functions are rated on a 5-point scale of frequency and scores are added up to a maximum of 16 points with a higher score indicating more frequent participation.
Return to Sports Index (RSI) at 6, 9, 12 months and at 2 years after surgery6 months thru 2 yearsMeasures the patients emotion, confidence, and risk appraisal when returning to sports after an ACL injury and/or reconstructive surgery. There are 12 questions and the subjects answer each in range is from 0 to 100. The response scale meaning is dictated by the question. The sum of all questions are reported, divided by 12,000 and multiplied by 100 to get a %.
VAS (Visual Analog Scale) Pain Score from post op through the first 12 months (approximately every 12 weeks) and at 2 years after surgery1 yearA tool widely used to measure pain. The patient indicates his/her perceived pain intensity along a 100 mm horizontal line and this rate is then measure from the left edge to give a score.
Current Status Questionnaire2 yearsElements include return to activity, pain medication use. No Score.
Pain Medication Use2 yearsAdministered by questionnaire. No score.
