About this study

Official title: Indications for Osteochondral Allograft Transplantation by Evaluating Safety and Efficacy of Total Biologic Total Joint Replacement of Ankle Post-traumatic Osteoarthritis (PTOA)

With IRB approval, a prospective single-cohort clinical trial will be performed to assess safety and efficacy of total biologic arthroplasty of the ankle. With informed consent, patients (n=10) who require tibio-talar arthroplasty based on physical examination and diagnostic imaging will be enrolled. Primary criteria for inclusion will be Grade IV changes in the articular cartilage of the tibial plafond and/or talar dome as determined by physical examination, diagnostic imaging and/or arthroscopy by the attending surgeon. Exclusion criteria include acute injury to any other part of the affected lower extremity or inability to comply with the protocol.

After enrollment, patients will undergo standard ankle radiography and complete assessments (described below). Size-matched (standard clinical methodology) MOPSTM allografts (Musculoskeletal Transplant Foundation, Edison, NJ) from the same donor will be obtained to treat the entire tibiotalar joint. The affected joint will be treated with OCA transplants using our current technique and instrumentation. Osteochondral grafts including MOPSTM OCAs are regulated under U.S. Food and Drug Administration (FDA) section 361 of the Public Health Service Act and 21 Code of Federal Regulation 1271 that defines human cells, tissues or cellular or tissue based products (HCT/P).

Patients will follow a managed post-operative rehabilitation protocol that is standard for those that have had an osteochondral allograft to their ankle.

Range of motion and patient-reported outcome measures (PROMs) including VAS pain score, AOFAS, and PROMIS Mobility as well as complete radiographs (XR) of the affected ankle will be obtained prior to surgery and at 6 weeks, 3 months, 6 months, and 12 months after surgery to evaluate healing, function and evidence for arthrosis. MRIs for cartilage composition (12 months after surgery, and serum and urine biomarkers for treatment monitoring (preop, 6 and 12 months after surgery) will be performed. We will document all adverse events and complications, including joint or incision infection, graft failure, hardware failure, and arthrofibrosis. Patients with a VAS pain score >5 beyond 3 months postoperatively or clinical or diagnostic imaging evidence for nonunion or graft collapse will undergo MRI of the ankle to determine the appropriate clinical course of action. OCA survival will be determined based on maintenance of acceptable levels of pain (<2 VAS) and function and/or need for revision surgery or total ankle arthroplasty, fusion, or amputation.

What is being measured

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

  1. Visual Analog Scale (VAS) score

    Pain assessment which measures what a patient rates their pain between 0 and 10, with 0 being no pain, and 10 being the most pain

    Measured: 12 Months

Secondary outcomes (2)
  1. American Orthopaedic Foot and Ankle Society (AOFAS) score

    This measurement tool measures a patient's function out of 100, with 100 being highest amount of function

    Measured: 12 Months

  2. PROMIS - Physical Function and Mobility

    A survey related to physical function and mobility

    Measured: 12 Months

Questions about this trial

What is this clinical trial studying?

An observational study of Post-Traumatic Osteoarthritis of Ankle and Ankle Osteoarthritis, run by University of Missouri-Columbia at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Nov 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Visual Analog Scale (VAS) score (time frame: 12 Months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Nov 2022.
