Trial summary

Dextrose injection in end-stage knee arthritis will cause growth of cartilage cells in a particular area of complete cartilage loss. Dextrose concentration will be 12.5%. Cartilage status will be monitored by pre and post treatment arthroscopy views with specialized (methylene blue) staining for cartilage. Read more about this study

About this study

Official title: Biological Response of Stage IV Knee Osteoarthritis to Serial 12.5% Dextrose Injections Without Weight Bearing Restriction: A Double Arthroscopic Assessment

Dextrose injection in end-stage knee arthritis will cause growth of cartilage cells in a particular area of complete cartilage loss. Dextrose concentration will be 12.5%. Cartilage status will be monitored by pre and post treatment arthroscopy views with specialized (methylene blue) staining for cartilage.

Read the detailed description

Historical, compliance, examination,anesthetic injection, radiographic and arthroscopic screening will be completed. One month after arthroscopy completion, the intervention phase will begin.

INTERVENTION

  • Injection of 12.5% dextrose at 0, 1 and 2 months.
  • Stand up without using only the non-injected leg for 3 days after each injection.
  • Avoid running and squatting as feasible.
  • Ensure that the injected knee descends stairs first ascends stairs last for 3 days.
  • May take Acetaminophen.
  • No NSAIDS for 2 days before and 10 days after a treatment. PRN NSAIDs only.
  • No glucosamine or chondroitin should be taken.

SECOND ARTHROSCOPY TIMING

  • A minimum of 4 months after first arthroscopy, when schedulable.
  • After a minimum of 3 monthly injections of dextrose 12.5% .

METHOD OF ARTHROSCOPY

  • Only the medial compartment will be entered to minimize trauma.
  • Methylene blue will be applied and allowed to remain in knee for 5 minutes prior to flush.
  • A standardized method video scan of the medial femoral compartment will be conducted.
  • At second arthroscopy, the area of heaviest cartilage growth, if any, in the base of the Out-IV lesion will be biopsied with a Jamshidi needle at a 45 degree angle. (Limited by the optics of single port entry ).
  • Biopsy, if taken, will be sent for decortication to enable specimen to be cut, safranin O application to determine proteoglycan production, polarized light to differentiate fibrous from hyaline cartilage, and immunohistologic straining for Type I and Type Ii cartilage.

What participants receive

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

  • Dextrose intraarticularly administeredDrug

    Also called Glucose

    9 ml of 12.5% dextrose

What is being measured

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

  1. Quality of cartilage growth

    A Jamshidi needle biopsy will be obtained at 45 degrees in the area of maximum cartilage growth and analyzed for quality/type of cartilage if such growth is seen.

    Measured: 0 to 3 months

  2. Number of sections of medial condyle with loss, no change or growth of cartilage.

    Arthroscopy of all 9 sections of the medial condyle for each of 6 knees will be viewed by each of 3 arthroscopers who will render their opinion for each section. They will compare sections from 1st and 2nd arthroscopy side by side, and will be asked to indicate loss of cartilage no change or growth of cartilage for each of sections on each of 6 knees.

    Still photos of the biopsy study site wiThe photo of the Out IV lesion will be analyzed in a blinded fashion for a visual or computerized assessment of the percentage of lesion size covered by cartilage buds.

    Measured: 7.5 month mean

Secondary outcomes (3)
  1. Walking pain

    Subjects will be asked to estimate their walking pain on a 10 point scale over the preceding 2 weeks.

    Measured: 0 to 3 years

  2. Flexion range of motion

    The total flexion range of motion of the knee will be measured goniometrically.

    Measured: 0 to 3 months

  3. WOMAC

    WOMAC will be administered at time 0 and at time of the 2nd arthroscopy.

    Measured: 7.5 Months

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Dextrose intraarticularly administered in people with Knee Osteoarthritis, run by Universidad Nacional de Rosario at 1 site in Argentina.

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 9 inclusion and 20 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 20 May 2014. 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 Argentina. 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.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Quality of cartilage growth (time frame: 0 to 3 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01210183, which also lists 1 linked publication.

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 20 May 2014.
