Brief Summary:
The proposed research study aims to evaluate the effects of autologous bone marrow aspirate concentrate (BMAC) on the development and progression of osteoarthritis (OA) in patients undergoing meniscectomy. This prospective, randomized, double-blind clinical trial will compare patient-reported outcomes, specifically IKDC scores between patients who receive BMAC post-meniscectomy and those who receive a saline control injection. The study will also compare physical examination, MRI, radiographs, and synovial fluid analysis. Our hypothesis is that those who receive the autologous BMAC injection after the procedure will have better outcomes than those who do not.

Condition or disease Intervention/treatment Phase
Osteoarthritis Post-meniscectomy Biological: Bone Marrow Aspirate Concentrate Procedure: Standard Meniscectomy Not Applicable

Detailed Description:

Recent studies have demonstrated both the safety of BMAC intra-articular injection and improvements in subjective, patient reported outcomes in patients with existing knee OA. Unfortunately these studies were largely uncontrolled, underpowered, and/or retrospective in nature. Additionally, a recent prospective, randomized clinical study of allograft mesenchymal stem cells (MSCs) injected at a separate time point post surgical intervention has highlighted the ability of MSCs to increase meniscal volume and improve knee pain following injection.

This will be the first study to examine the effects of autograft BMAC intra-articular injection in a single-stage procedure and in a prospective, randomized, double-blind fashion. The results of this study, if the null hypothesis is rejected, will have far-reaching implications for the standard of care in meniscal treatment and on OA progression in the knee. Additionally, if the results of this study are favorable in reduction of OA progression this study will change the surgical approach to all axial, synovial joints including the shoulder, elbow, wrist, hip, and ankle.

Arm Intervention/treatment
Experimental: Meniscectomy with Bone Marrow Aspirate Concentrate (BMAC)
Subjects will undergo the scheduled meniscectomy procedure. Following the procedure the investigator will make a small incision and create the marrow access channel in the proximal tibia. The experimental group will then have bone marrow harvested and BMAC will be prepared using a BMAC harvesting system. The automated centrifuge system rapidly concentrates cellular contents and growth factors in bone marrow aspirate using flow cytometry. The BMAC will be injected intra-articularly.
Biological: Bone Marrow Aspirate Concentrate
Subjects undergoing autologous bone marrow aspirate concentrate will receive an intra-articular injection into the affected knee.

Procedure: Standard Meniscectomy
All subjects will undergo either a partial or complete meniscectomy to treat the torn meniscus.

Placebo Comparator: Meniscectomy with Placebo
Subjects will undergo the same meniscectomy procedure and will also have an incision and marrow access channel made in the proximal tibia, however no bone marrow will be harvested. The control group will have a placebo injection of saline into the affected knee.
Procedure: Standard Meniscectomy
All subjects will undergo either a partial or complete meniscectomy to treat the torn meniscus.

Primary Outcome Measures :
  1. International Knee Documentation Committee (IKDC) Score [ Time Frame: One Year ]
    The primary outcome measure will be the IKDC score at one year follow-up

Secondary Outcome Measures :
  1. Patient reported outcomes throughout follow-up period [ Time Frame: 7-10 days, 6 weeks, 3 months, 6 months, 1 year, 2 years ]
    Patient reported outcomes will include change in scores from preoperative to postoperative Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Visual Analog Score (VAS), International Knee Documentation Committee form (IKDC), Knee injury and Osteoarthritis Outcome Score (KOOS) and SF-12.

  2. Synovial fluid analysis [ Time Frame: 2 weeks, 6 weeks ]
    To investigate any changes in synovial fluid markers of osteoarthritis.

  3. Radiographic analysis [ Time Frame: 1 year, 2 years ]
    The degree of OA will be examined in all patients preoperatively and at subsequent follow-up visits at 1 and 2 years.
