About this study

The primary purpose of this study is to evaluate laparoscopic gastric banding (LAGB) surgery as a treatment option for obese patients with pain from knee osteoarthritis (KOA) refractory to medical treatment. The primary outcome will be the reduction in OA-related pain and disability after LAGB.

Read the detailed description

This is a pilot study of 15 (may need to consent/screen 30 patients to have 15 enrolled) obese patients (BMI 30-40) with painful knee osteoarthritis. Although prior studies have reported musculoskeletal secondary outcomes following various types of bariatric surgery, investigators propose the evaluation of laparoscopic gastric banding (LAGB) to treat a cohort of patients with moderate to severe knee osteoarthritis.

Once eligible patients are identified by rheumatologists and/or bariatric team and consented for the study, they will have bilateral knee radiographs (standard of care) to ensure they have a sufficient degree of OA. Patients will then be referred to the bariatric surgeons, who will then confirm the patients' interest, understanding and suitability for the LAGB surgery which is a FDA approved procedurefor patients with a BMI >30 and at least one obesity-related comorbidity (including knee OA)37. It is the application of this approved procedure that constitutes the research question should LAGB surgery be considered as a treatment option to improve pain and physical disability in patients with knee OA? During the pre-operative process patients will be given study questionnaires to evaluate knee pain and function, have a musculoskeletal exam and blood/urine will be collected.These procedures will be repeated at post-operative intervals to track response of the knees to the LAGB.

The primary outcome measure is improvement in OA-related knee pain and physical disability. Improvement of pain and function will be defined by changes in the VAS, WOMAC, AORC and KOOS scores. The degree of improvement required to qualify as such will be described in the methods sections below.

Secondary outcome measures include (1) radiographic evidence of OA progression or worsening despite the LABG, (2) weight loss, and (3) reduction or discontinuation of pain medication.

Questions about this trial

What is this clinical trial studying?

A study testing bariatric lap band surgery in people with Knee Osteoarthritis, run by NYU Langone Health 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 8 inclusion and 13 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 11 Feb 2020. 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?

reduction in OA-related pain and disability after LAGB. (time frame: 4 years). 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 11 Feb 2020.
