About this study
Official title: Assessment of Short-term Effectiveness of Five Local Treatment Modalities in Patients With Symptomatic Knee Osteoarthritis: a Randomized Prospective Study
BACKGROUND: Current medical treatment strategies for knee osteoarthritis (OA) are aimed at pain reduction and symptom control. The Non-Arthroscopic Joint Lavage (NAJL) is included inside the therapeutic algorithm of knee OA when other therapies are contraindicated or have lost effectiveness. The large variety of potentially invasive interventions available (joint lavage included) has raised the need to assess their efficacy. The objective of this study is to compare the short-term effectiveness of five treatment strategies in patients with knee osteoarthritis (OA).
METHODS: It was conducted a randomized prospective study involving 150 patients of whom 76.7% were females. The age range was 40-81 years. All patients had knee OA according to the American College of Rheumatology criteria, with Kellgren-Lawrence radiographic grades II and III. Patients were assigned to five groups, 1) non-arthroscopic joint lavage (NAJL) (n= 30), 2) NAJL plus hyaluronic acid (HA) (n= 32), 3) NAJL plus corticosteroid (CS) (n= 32), 4) HA (n= 31), 5) CS (n= 25). Evaluations took place at baseline, one and three months after enrollment. Demographic variables, Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and Lequesne scores were recorded. Statistical analysis included mixed analysis of variance, post-hoc comparisons with Sidak's adjustment, and multiple linear regression using as outcome WOMAC total at 3 months.
TRIAL REGISTRATION: The protocol of the study was approved by the "Hospital Universitario Reina Sofía" Ethics Committee, under the number 1996, in the Minutes 208 of 29 May 2012.

| Study group | Role | What they receive |
|---|---|---|
| Non arthroscopic joint lavage (NAJL) | Active comparator | Establishment of sterile areas and cleaning of the skin around the knee with a povidone-iodine solution, followed by an injection of local anesthetic (5 mL of 2% mepivacaine hydrochloride) into the outer mediopatellar zone. The anesthetic was allowed to act, and an access way was then opened with a No. 16 abocat. Any effusion in the joint was drained. Then, approximately 100 mL of cold saline was instilled through the outer access way. Once the knee was distended, a further 5 mL of local anesthetic was injected into the inner mediopatellar zone, and a new abocat guide was used to establish the inner drainage way. The lavage proper involved instillation of 4 L of cold (8ºC) saline at a constant flow-rate using a dropper line connected to the entry way; the inner zone was also connected to another, free-fall dropper.

What is being measured
The primary outcome is the main question the study is designed to answer.
WOMAC 3.1 Index total
The WOMAC (Western Ontario and McMaster Universities) index is used to assess patients with osteoarthritis of the hip or knee and contains 24 questions, targeting areas of pain, stiffness and physical function. It can be used to monitor the course of the disease or to determine the effectiveness of anti-rheumatic medications. In the study it was used the validated Spanish version of the 5-point adjectival scale format (possible answers are none -0 points-, slight -1 point-, moderate -2 points-, severe -3 points- and extreme -4 points-). The WOMAC measures five items for pain (score range 0-20), two for stiffness (score range 0-8), and 17 for functional limitation (score range 0-68). WOMAC total is the sum of the three components and it ranges from 0 to 96 points, being 96 the worst outcome.
Measured: WOMAC total at 3 months
Secondary outcomes (12)
Lequesne Index
Lequesne Index is a ten question questionnaire that asseses pain and function in patients with osteoarthritis of the knee. It is composed by five questions about pain, being three of them from 0 to 2, and two of them from 0 to 1 point, two questions about maximum distance walked (from 0 to 6 points one and from 0 to 2 the second) and four questions about activities of daily living (from 0 to 2). The total values is the sum of all questions points and range from 1 to 24, being 1-4 mild handicap, 5-7 moderate, 8-10 severe, 11-13 very severe, and >14 extremely severe handicap.
Measured: baseline, at one month and at three months

WOMAC 3.1 Index total
Time frame: WOMAC total at 3 months
The WOMAC (Western Ontario and McMaster Universities) index is used to assess patients with osteoarthritis of the hip or knee and contains 24 questions, targeting areas of pain, stiffness and physical function. It can be used to monitor the course of the disease or to determine the effectiveness of anti-rheumatic medications. In the study it was used the validated Spanish version of the 5-point adjectival scale format (possible answers are none -0 points-, slight -1 point-, moderate -2 points-, severe -3 points- and extreme -4 points-). The WOMAC measures five items for pain (score range 0-20), two for stiffness (score range 0-8), and 17 for functional limitation (score range 0-68). WOMAC total is the sum of the three components and it ranges from 0 to 96 points, being 96 the worst outcome.

Questions about this trial
What is this clinical trial studying?
A study testing Non arthroscopic joint lavage, Non arthroscopic joint lavage plus corticosteroid and Non arthroscopic joint lavage plus hyaluronic acid in people with Osteo Arthritis Knee, run by Maimónides Biomedical Research Institute of Córdoba.
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 6 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 21 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.
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?
WOMAC 3.1 Index total (time frame: WOMAC total at 3 months). 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 NCT03783455, 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 21 Dec 2018.
