Study Details

Brief summary:

The goal of this pilot randomized clinical trial is to look into the efficacy of concentrated bone marrow aspirate (cBMA) in improving post traumatic osteoarthritis (PTOA) symptoms in patients undergoing revision anterior cruciate ligament reconstruction surgery. The main questions it aims to answer are whether clinical outcomes, such as pain, are improved in patients who get cBMA with surgery, if there is a change in circulating markers of inflammation and what part of the cellular and molecular composition of cBMA may explain its effects.

Eligibility Criteria

Sex: All

Age: 18 - 55

Healthy Volunteers: Not accepted

Inclusion Criteria:

  • Males and Females
  • Age 18 to 55
  • Previous unilateral ACLR (Anterior Cruciate Ligament Reconstruction) within the last 5 years, and identified as having experienced failure of the primary ACLR
  • Scheduled to have a revision ACLR surgery, with any graft type (including patellar tendon, hamstring, quad or allograft)
  • Able to complete all study procedures and participate in a standardized physical therapy program

Exclusion Criteria:

  • History of inflammatory arthritis or joint sepsis
  • Prior or concurrent total or sub-total meniscectomy
  • Prior or present avascular necrosis of the index knee
  • Oral or intra-articular corticosteroid injection within 3 months
  • Hyaluronic acid or PRP (Platelet-Rich Plasma) injection within 6 months
  • Use of duloxetine, doxycycline, indomethacin, glucosamine and/or chondroitin (ongoing or within 2 months)
  • Any clinical or laboratory abnormality greater than grade 3 CTCAE, which in the view of the investigator, will compromise the participant's safety.

Interventions and Outcome Measures

Arms

experimental: Investigational Arm

Patients undergoing revision anterior cruciate ligament reconstruction surgery will get an intraoperative injection of concentrated bone marrow aspirate (cBMA).

sham comparator: Control Arm

Patients undergoing revision anterior cruciate ligament reconstruction surgery will get a sham incision in lieu of bone marrow harvesting.

Interventions

Concentrated Bone Marrow Aspirate Injection

Intraoperatively, bone marrow will be harvested from the iliac crest with a commercial kit, it will then be prepared via centrifugation and an injection of the resulting concentrated product (cBMA) will be administered in the operative knee. cBMA is an autologous biologic product.

Sham Incision

A 2 mm sham incision will be made in the anatomical site where bone marrow would be harvested.

Revision Anterior Cruciate Ligament Reconstruction

This is the standard-of-care surgical procedure.

Primary outcome measure

  • Change from baseline in patient reported knee pain [ Time Frame: Baseline, 6 weeks, 6 months, 12 months and 24 months post-operative ]
