Clinical Trial 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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	International Knee Documentation Committee Subjective Score (IKDC) (Survey)	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.	Time points up to two years
Primary	International Knee Documentation Committee Objective Score (IKDC) (Physical Exam)	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.	Time points up to two years.
Secondary	Knee Injury and Osteoarthritis Score (KOOS) questionnaire	This 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.	Time points up to two years
Secondary	Repair Failure	The number of times patients develop recurrent knee stability and require another ACL surgery.	Two years
