NCT03696394

Brief Summary

The study was designed by the principal investigator, Dr. Andrea Veljkovic, and the St. Paul's Hospital Foot and Ankle Research Group, who will conduct the study. The study is being funded by Arthrex, Inc., the manufacturer of the Health Canada approved BioCartilage® Micronized Cartilage Matrix. The purpose of this study is to assess whether adding BioCartilage® to microfracture treatment of osteochondral defects of the talus improves osteochondral healing as well as improving pain and function. Efficacy will be assessed primarily by outcomes scores as measure by the Ankle Osteoarthritis Scale (AOS) at the baseline and at multiple post-op followup visits. Additional outcomes scores will also be administered to compare general health and foot function between the two groups at baseline and at multiple post-op followup visits. X-rays and MRI will be used to assess the osteochondral healing rate.

Outcome Measures

Primary Outcomes (1)

  • Changes as Assessed by Ankle Osteoarthritis Scale (AOS)

    This questionnaire assesses pain and difficulty in both the left and right ankle. The range for the Pain subscale is from 0 to 100 and the range for the Difficulty subscale is 0 to 100. The range for the Total score (average of Pain and Difficulty) is 0 to 100. Lower values for Pain, Difficulty, and Total is considered better. The scores will be compared to each other to analyze the change in pain and difficulty from the baseline (within 21 days of surgery) to the end (2 years post-op).

    Outcome will be administered 6 times per patient: within 21 days of surgery, 6 weeks post-op, 12 weeks post-op, 6 months post-op, 1 year post-op and 2 years post-op.

Secondary Outcomes (6)

  • Musculoskeletal Outcomes Data Evaluation and Management System (MODEMS) including Short Form 36 Health Survey (SF-36)

    Outcome will be administered 6 times per patient: within 21 days of surgery, 6 weeks post-op, 12 weeks post-op, 6 months post-op, 1 year post-op and 2 years post-op.

  • Foot and Ankle Ability Measure (FAAM)

    Outcome will be administered 6 times per patient: within 21 days of surgery, 6 weeks post-op, 12 weeks post-op, 6 months post-op, 1 year post-op and 2 years post-op.

  • Visual Analog Scale

    Outcome will be administered 6 times per patient: within 21 days of surgery, 6 weeks post-op, 12 weeks post-op, 6 months post-op, 1 year post-op and 2 years post-op.

  • X-ray radiographic assessments performed pre-operatively and post-operatively

    There are 6 assessment time points: within 21 days of surgery, 6 weeks post-op, 12 weeks post-op, 6 months post-op, 1 year post-op and 2 years post-op.

  • CT radiographic assessments performed pre-operatively and post-operatively

    There are 2 assessment time points: within 21 days of surgery and 2 years post-op.

  • +1 more secondary outcomes

Eligibility Criteria

Age19 Years+

Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • The subject has signed the REB approved informed consent form (ICF) specific to this study prior to enrollment.
  • The subject has an isolated OCD with minimum dimensions of 0.07 cm2 (0.3 cm in diameter) and maximum dimensions of 2.25 cm2 as confirmed by a pre-op MRI.
  • The subject is independent, ambulatory, and can comply with all post-operative evaluations and visits.
  • The subject is at least nineteen (19) years of age and considered to be skeletally mature.
  • The subject has a combined bone and cartilage defect as determined by an MRI.
  • The patient has a stable ankle joint on history and has similar ligament stability with the opposite ankle.
  • The subject has less than 15 degrees of hindfoot valgus and 5 degrees of hindfoot varus.
  • The subject has a chronic defect not secondary to acute trauma within the last 6 months.
  • The patient (if having suffered a fracture) has no residual deformity of the tibia, fibula or syndesmosis.
  • The subject has a BMI of ≤ 40 kg/m².
  • The subject has exhausted non-operative treatment.

  • The subject has over 15 degrees of hindfoot valgus or 5 degrees of hindfoot varus.
  • The subject has an isolated OCD with dimensions greater than 2.0 cm2 on an MRI assessment.
  • The subject has an allergy to yeast-derived products.
  • The subject has implanted metallic devices (cardiac pacemakers, insulin pumps, and nerve stimulators), medically implanted clips, or other electronically, magnetically or mechanically activated implants that would contraindicate an MRI scan of the foot.

  • The subject has tested positive or has been treated for a malignancy in the past, is suspected of having a malignancy, or is currently undergoing radiation or chemotherapy treatment for a malignancy anywhere in the body, whether adjacent to or distant from the proposed BioCartilage® site.
  • The subject is physically or mentally compromised (e.g., currently being treated for a psychiatric disorder, senile dementia, Alzheimer's disease, etc.), to the extent that the investigator judges the subject to be unable or unlikely to remain compliant to follow-up.
  • The subject is a prisoner, or is known or suspected to be transient.
  • The subject has documented evidence of a history (e.g. liver testing) of drug/alcohol abuse within the 12 months prior to screening for study entry.
  • The subject is pregnant or able to become pregnant but not practicing a medically-accepted form of birth control, and/or intending to become pregnant during this study period.
  • The subject currently has an acute infection in the area surrounding the surgical site.
  • The subject has a history of anaphylaxis or of multiple non-environmental allergies that may precipitate an anaphylactic reaction.
  • The subject's condition is bilateral and surgery is scheduled or to be scheduled over the course of this trial for both feet.
  • The subject requires a concomitant osteotomy of the tibia, fibula, or calcaneus for hindfoot deformity.
  • The subject requires a concomitant hindfoot fusion or has had a hindfoot fusion for hindfoot arthritis or deformity.
