The primary objective of this study is to compare the improvement in subject-reported clinical outcomes for Regenexx SD vs. Exercise Therapy treatment of partial and complete, non-retracted knee ACL ligament tears, from baseline to 3 months, with continued evaluation of efficacy and durability up to 24 months.
Secondary objectives include evaluation of MRI evidence of tendon repair; incidence of post-operative complications, adverse events, re-injections, and surgical intervention; change in pain score and use of pain medications.
|Condition or disease||Intervention/treatment||Phase|
|Anterior Cruciate Ligament Tear||Procedure: Regenexx SD Other: Exercise Therapy||Not Applicable|
Prospective, randomized, controlled to include 25 subjects treated with Regenexx SD and 25 subjects treated with exercise therapy alone with the exercise group crossing over to the injection group at 3 months.
Subjects will have a partial or complete, non-retracted ACL ligament tear as evidenced with MRI.
Subjects will be enrolled within 60 days prior to Regenexx-SD injection or initiation of exercise therapy and take part in follow-up visits for two years following treatment. A preoperative visit will occur at the time of enrollment; follow-up visits will occur at the clinical site at 6 weeks, 3 months, 6 months, 12 months, and 24 months post injection.
The primary endpoint analysis will be conducted once all subjects reach the 3 month endpoint. Subjects will continue to be followed through the 2 year endpoint with data analysis performed at the 1 year and 2 year time points.
