Brief Summary

Osteonecrosis of the femoral head (ONFH) is a debilitating musculoskeletal disease that is characterized by localized death of bone cells and associated cellular elements within the subchondral bone. If it progresses, it results in the collapse of the femoral head (ball part of the hip) giving rise to secondary arthritis. This condition is associated with marked pain and loss of function, often necessitating a joint replacement. Due to the relatively young age of onset of ONFH (often in 20s and 30s), there is great interest in utilizing joint-preserving procedures prior to the need for joint replacement. Joint-preserving procedures include core decompression (CD) with and without bone grafts or cells, vascularized and non-vascularized bone grafting, as well as osteotomies. Inconsistent results for each of these procedures have been reported and there are no Clinical Practice Guidelines or medical community consensus opinions regarding the treatment of early-stage ONFH. The hypothesis to be tested is "Participants who have early-stage ONFH undergoing CD augmented with autogenous bone marrow aspirate concentrate will have better clinical and radiological outcomes than CD alone." This multi-center randomized controlled trial for early-stage ONFH is prospective and controlled for participant stage (only early-stage pre-collapse individuals) and surgical technique. Participants will be evaluated as per routine surgical follow-up, and at 6 months (telemedicine), 1- and 2- years using radiographs, MRIs, and questionnaires. This project will also explore the scientific basis for success vs. failure in individuals who have osteonecrosis, and have different demographics and bone marrow aspirate cell profiles.

Outcome Measures

Primary Outcomes (3)

  • Radiological progression of osteonecrosis of the femoral head (ONFH) to ARCO Stage III or IV

    The 2019 ARCO Staging System encompasses four stages. ARCO Stage I is the earliest stage of osteonecrosis and is characterized by a normal x-ray and an abnormal MRI. ARCO Stage IV is the most advanced stage of osteonecrosis and is characterized by findings of osteoarthritis on x-ray.

    Up to 24 months

  • Change in Pain using the Pain VAS scale

    This is assessed using the pain Visual Analogue Scale (VAS). The participant marks an X on a 10cm scale denoting the level of pain that they are experiencing. VAS measures pain intensity on a scale of 0 (no pain) to 10 (worst pain).

    Up to 24 months

  • Time to failure of femoral head

    Time is measured in months following the intervention (core decompression or core decompression with cells). Failure is defined as radiological progression to ARCO Stage III or IV or unremitting pain requiring surgical intervention.

    Up to 24 months

Secondary Outcomes (8)

  • Change in Pain using the Hip disability and Osteoarthritis Outcome Score (HOOS)

    Baseline, 6 months, 12 months, 24 months

  • Change in Symptoms and Stiffness using the HOOS

    Baseline, 6 months, 12 months, 24 months

  • Change in Activities of Daily Living function using the HOOS

    Baseline, 6 months, 12 months, 24 months

  • Change in Function in Sports and Recreational Activities using the HOOS

    Baseline, 6 months, 12 months, 24 months

  • Change in Quality of Life using the HOOS

    Baseline, 6 months, 12 months, 24 months

  • +3 more secondary outcomes

Study Arms (2)

Core decompression (CD)

ACTIVE COMPARATOR

Core decompression of the femoral head with sham bone marrow aspiration

Procedure: Core Decompression

Bone Marrow Aspirate Concentrate (BMAC)

EXPERIMENTAL

Autologous bone marrow aspiration is concentrated and injected into the necrotic bone of the femoral head through the core decompression opening.

Procedure: Core DecompressionProcedure: Core Decompression Procedure with Autologous Bone Marrow Aspirate Concentrate

Interventions

Standard core decompression procedure is performed by drilling into the necrotic bone of the femoral head. A sham bone marrow aspiration involves advancing a needle to the iliac crest (no bone penetration, no bone marrow aspiration) through a small skin incision.

Bone Marrow Aspirate Concentrate (BMAC)Core decompression (CD)

This involves bone marrow aspiration, concentrating the bone marrow aspirate, and injecting 6 milliliters of bone marrow aspirate concentrate into the necrotic femoral head through an opening created by the core decompression.

Masking Details
Participants will be blinded as to group assignment. Both groups will undergo a core decompression. One group will undergo a bone marrow aspiration and the other group will undergo a sham procedure. This sham procedure consists of a small incision and placing a needle up to the iliac bone but with no bone penetration or aspiration. The study radiologists will be blinded as to patient treatment assignment; images will be assigned the patient study number and date only.
