Trial summary

This study compared the effects of tidal lavage (washing out) of the knee joint and an imitation lavage procedure in people with knee osteoarthritis. In tidal lavage, the doctor flushes out a knee joint with repeated injections of a mild salt solution, done under local anesthesia. Read more about this study

About this study

Official title: Tidal Lavage vs. Sham Lavage in Knee Osteoarthritis (OA)

This study compared the effects of tidal lavage (washing out) of the knee joint and an imitation lavage procedure in people with knee osteoarthritis. In tidal lavage, the doctor flushes out a knee joint with repeated injections of a mild salt solution, done under local anesthesia. Study participants had to meet standard criteria for diagnosis of osteoarthritis but could have low, medium, or high severity of x-ray changes indicating knee osteoarthritis. We performed the lavage procedure once, and did quarterly followups for 1 year. We permitted patients to use some other osteoarthritis treatments during the study, such as non-narcotic pain relievers, nonsteroidal anti-inflammatory drugs, and physical therapy.

Read the detailed description

This study was a randomized, double-blind, sham procedure-controlled evaluation of tidal lavage as a treatment for knee osteoarthritis. We achieved blinding by raising a drape during the study procedure and mimicking the sensory aspects of tidal lavage, but not flushing the knee, in the sham lavage group. We gave all study participants subcutaneous anesthesia with lidocaine and then bupivacaine and then attempted aspiration of the knee, removing up to 5 ml of synovial fluid for examination and then injecting the knee with 20 ml of bupivicaine.

In people who received the sham treatment, we placed a 16-gauge catheter in the lateral suprapatellar position just to the knee joint capsule and infused small volumes (less than 5 ml per "exchange" x 20) of saline into the subcutaneous tissue while manipulating the anterior knee to mimic efforts to shift fluid within the knee during the "aspiration" phase of each exchange. Patients could see the supply bag of sterile saline but could not see the waste bag of this closed drainage system.

For tidal lavage patients, we made the catheter puncture in the lateral suprapatellar pouch and repeatedly distended the knee with 30-50 ml of sterile saline, then aspirated this volume (about 20 exchanges for a total of 1 liter of flush solution).

At the end of the procedure, we told the patients that their knee might be swollen due to retained saline, and to expect this additional swelling to resolve over 24-48 hours, during which time they were to minimize activity. The person who did the procedure (the principal investigator) then left the room. The study nurse, who was not present for the procedure and was blinded to the procedure's identity, asked the patients which treatment they thought they received (tidal lavage or sham lavage). We scheduled patient followups with this study nurse for 3, 6, and 12 months, and patients completed questionnaires at each visit. Questionnaires were both arthritis-specific (WOMAC) and global (Quality of Well-Being).

Questions about this trial

What is this clinical trial studying?

A Phase 2 study of Osteoarthritis, Knee, run by National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) 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 3 inclusion and 5 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 1 Jan 2007. 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.

What does this 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.

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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00000424, which also lists 4 linked publications.

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 1 Jan 2007.
