This is a prospective, randomized, placebo-controlled trial. Patients will be randomized into three groups: Concentrated Bone Marrow Concentrate (BMC), Platelet-Rich Plasma (PRP) or Placebo. BMC subjects will have bone marrow aspirated from the subjects iliac crests and the cellular rich portion will be concentrated and subsequently injected into the subjects' symptomatic knee during ACL reconstruction surgery. PRP subjects will have a venous blood draw and the resulting PRP will be injected into the symptomatic knee during ACL reconstruction surgery. Follow-up visits in person will take place at 2 weeks, 6 months and 12 months after the ACL reconstruction surgery.~The purpose of this study is to evaluate potential beneficial effects of leukocyte-poor platelet-rich plasma (LP-PRP) and bone marrow concentrate (BMC) on the healing and health of all critical joint tissues (grafts/ligaments, meniscus and cartilage) in the knee following anterior cruciate ligament reconstruction (ACLR). Key aspects of this proposal include our well-developed methodologies to quantify and correlate cytokines, chemokines, growth factors in PRP and progenitor cells in BMC, clinical outcomes and imaging following ACLR. The overarching goal of this randomized control trial is to establish a biological signature of PRP and BMC that will be indicative for optimal recovery after ACLR. The long-term goal of our research is to better understand the efficacy of orthobiologic approaches to improve clinical outcomes, enhance graft healing and mitigate post-traumatic osteoarthritis (PTOA) in a cohort of patients that have undergone ACLR.
This is a prospective, randomized, placebo-controlled trial to evaluate potential beneficial effects of leukocyte-poor platelet rich plasma and bone marrow concentrate on the healing and health of critical joint tissues in the knee following anterior cruciate ligament (ACL) reconstruction. Bone marrow contains stem cells which can change into cells of various different tissue types, while platelet rich plasma contains growth factors. This trial will compare the two procedures against placebo.
