Trial summary

Femoroacetabular impingement (FAI) is a hip disorder resulting from a mismatch of the hip joint, resulting in hip pain and can potentially cause osteoarthritis. As the head of the femur (ball of the hip) and the acetabulum (socket of the hip) impinge or rub together with this mismatch, patients can suffer damage to… Read more about this study

About this study

Official title: Cartilage Repair Using a Hyaluronic Acid-Based Scaffold With Bone Marrow Aspirate Compared With Microfracture for Focal Articular Cartilage Damage of the Hip: A Randomized Controlled Trial

Femoroacetabular impingement (FAI) is a hip disorder resulting from a mismatch of the hip joint, resulting in hip pain and can potentially cause osteoarthritis. As the head of the femur (ball of the hip) and the acetabulum (socket of the hip) impinge or rub together with this mismatch, patients can suffer damage to their articular cartilage which covers both. Currently, the standard of care to surgically treat articular cartilage damage is a procedure called 'microfracture' - where the surgeon makes multiple holes in the bone under the defects causing bone marrow cells and blood from the holes to combine to form a "super clot" that covers the damaged area and is meant to be the basis for new tissue formation or 'fibrocartilage'. However, native articular cartilage is made of hyaline, rather than fibrocartilage, which is a more flexible and durable tissue able to withstand a great deal of force on the hip when it moves. Therefore, a more recently developed strategy that has gained popularity for use in the repair of articular cartilage in the knee involves the implantation of bone marrow aspirate (BMA) along with a scaffold made of hyaluronic acid (HA) in a single-step procedure, with the goal of promoting new hyaline-like tissue. While this has shown promising results in treating knee cartilage damage, this treatment method has yet to be studied in the hip. This randomized controlled trial will evaluate in patients with painful articular cartilage damage of the hip, the effect of implantation of an HA scaffold along with BMA in comparison to microfracture on hip pain and function, cartilage regeneration, and any complications at 24 months post-surgery.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • HA-based scaffold with BMA (Hyalofast®; Anika Therapeutics, Bedford, MA, USA)Device

    General surgical and anaesthetic risks apply to the subjects included in the trial. Microfracture and BMA are surgical techniques currently being used and are approved for use in Canada. The HA-scaffold that will be used in this trial (Hyalofast®, Anika Therapeutics Inc.) has European CE Mark for use in all joints. We will obtain a Health Canada approval to use the Hyalofast® product in the hip for this trial.

Study groups in NCT04875767
Study groupRoleWhat they receive
HA-based scaffold with BMA (Hyalofast®; Anika Therapeutics, Bedford, MA, USA)ExperimentalThose allocated to the scaffold treatment group will have 30 ml of BMA harvested from the ipsilateral iliac crest under fluoroscopic guidance. The hip arthroscopy will then be resumed, and the damaged cartilage lesion will be debrided using a mechanical shaver to remove loose and calcified tissue. Once the walls of the lesion are confirmed to be stable with a probe, the exact size of the defect will be measured for templating of the scaffold. The biodegradable HA-based scaffold (Hyalofast®; Anika Therapeutics, Bedford, MA, USA) will be prepared by cutting it to fit the focal defect. Once the cartilage lesion is dried manually, this scaffold will be implanted into the defect after it has been soaked in the BMA. The scaffold will then be secured to the defect in a press-fit fashion to the surrounding cartilage. In the case where additional fixation of the scaffold is needed, such as uncontained shoulder of cartilage, fibrin glue will be used to secure the scaffold.

MicrofractureActive comparatorAs per current standard of care for focal articular cartilage lesions of the acetabulum, the unstable cartilage will be debrided and removed from the subchondral bone using a mechanical shaver until a stable margin is obtained. A ring curette will be used to remove the calcified cartilage layer and create a border of healthy cartilage tissue that can support the marrow clot. Through the mid-anterior portal, specialized 90˚ awls will then be placed with the tip perpendicular to the subchondral bone of the acetabulum, and a mallet will be used to penetrate the subchondral bone with perforations 3 mm deep to access the bone marrow elements. This is done until the defect is homogeneously covered with micro-perforations 2-3 mm apart.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. International Hip Outcome Tool-33 (iHOT-33)

    The iHOT-33 is designed to measure hip-specific health-related quality of life changes after treatment of active young patients with hip disorders. The questionnaire has been validated in this patient population and has demonstrated efficacy, reliability, and responsiveness to change.

    Measured: 24 months

Secondary outcomes (4)
  1. Visual Analogue Scale (100-point scale) (VAS)

    The VAS is one of the most frequently used pain rating scales in clinical practice and research. The VAS is a validated unidimensional scale that is easy to use, requires no verbal or reading skills, and is sufficiently versatile to be employed in a variety of settings.

    Measured: 24 months

  2. Euro-Qol 5-D (EQ-5D)

    The EQ-5D is a standardized, utility-based instrument for use as a measure of health outcome. It comprises 5 questions on mobility, self-care, usual activities, pain/discomfort, and anxiety/ depression. The EQ-5D has been used in previous studies involving patients with hip pain and has been extensively validated.

    Measured: 24 months

  3. Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART)

    The MOCART scale has been validated to demonstrate the extent of cartilage restoration following surgical repair, examining factors such as "degree of defect repair and filling of the defect", and "integration to border zone". The MOCART scale is applied to MRIs.

    Measured: 24 months

  4. Adverse events

    Reported complications such as infection, additional or revision surgery, hypersensitivity or allergic reactions, reduced range of motion, and any other adverse events.

    Measured: 24 months
