Overview
Brief Summary
Bridge-Enhanced ACL Restoration (BEAR) is a new procedure being developed to treat patients with ACL injuries. In the BEAR procedure, an implant is placed between the torn ends of the ACL and the patient's own blood is added to the implant to stimulate ligament healing. We propose the current study to determine if older patients do better than younger patients (or vice versa) with this procedure. This is a cohort study designed to determine if age is a risk factor for a worse outcome after a bridge-enhanced ACL repair (BEAR) as defined by an 11.5 point difference on the IKDC Subjective or Objective Knee Evaluation score at two years after surgery. Additional objectives are to determine the effect of age on safety outcomes including infection, graft rejection, and need for further surgical procedures.
Detailed Description
The BEAR III study is a cohort study designed to determine if age is a risk factor for a worse outcome after a bridge-enhanced ACL restoration (BEAR) as defined by an 11.5 point difference on the IKDC Subjective or Objective Knee Evaluation score at two years after surgery. Additional objectives are to determine the effect of age on safety outcomes including infection, graft rejection, and need for further surgical procedures.

Eligibility Criteria
Inclusion Criteria
- •ACL tear, within 50 days of injury, at least 5% of the ACL attached to the tibia.
Exclusion Criteria
- •Prior surgery on the affected knee, history of knee infection, use of tobacco, use of corticosteroid, chemotherapy, allergy to bovine products or gelatin, history of anaphylaxis, BMI over 35, moderate osteoarthritis.
Outcomes
Primary Outcomes
International Knee Documentation Committee Objective Score (IKDC) (Physical Exam)
Time Frame: Time points up to two years.
This 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.
International Knee Documentation Committee Subjective Score (IKDC) (Survey)
Time Frame: Time points up to two years
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.
Secondary Outcomes
- Repair Failure(Two years)
- Knee Injury and Osteoarthritis Score (KOOS) questionnaire(Time points up to two years)
