About this study

Official title: Comparison of the Effects of Ultrasound Guided Genicular Nerve Block Versus Physical Therapy for Knee Osteoarthritis

Goal: Comparison of the effects of genicular nerve block with usg and physical therapy on pain, physical function for patients with knee osteoarthritis.

Material and Methods:102 patients with osteoarthritis of the knee with Kellgren-Lawrence (K-L) class 2 or 3 were included in the study.Patients were randomized to two groups, first being injected a total of 6 mL of lidocaine plus 40 mg of triamcinolone (TA) at 3 separate target sites: the superior lateral, superior medial, and inferior medial genicular nerves with exercise treatment and second being ten sessions of hotpack as a surface warmer, TENS as a analgezic current, ultrasound therapy as a deep warmer with exercise treatment.For the first group, the ultrasound we used: 12 MHz linear transducer. (Logic E9-GE, USA).The transducer was first placed parallel to the long bone shaft and moved up or down to identify the epicondyle of the long bone. The genicular arteries were identified near the periosteal areas, which are the junctions of the epicondyle and the shafts of the femur and tibia, and confirmed by color Doppler ultrasound.Accordingly, GNB target points should be next to each genicular artery because the superior lateral, superior medial, and inferior medial genicular artery traveled along each genicular nerve. , Visual Analogue Scale for pain(VAS) was primer outcome measurement, Western Ontorio and McMaster Universities Osteoarthritis Index (WOMAC) and six minute walk tests were seconder outcome measurements of the study applied before, after (two weeks) and 12th weeks of treatment. Primer endpoint of the study is decrease at least 40% in VAS values at 2nd week, second endpoint is the improvement in the womac and 6-minute walk test observed in the 2nd week continues until the 12th week.

What is being measured

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

  1. Visual analog scale (VAS) score

    A scale for the use of measuring pain. Minimum score of the scale is 0 and maximum is 10. Higher scores mean worse outcomes.

    Measured: Pre-intervention, Change from Baseline visual analog scale at 12th weeks

Secondary outcomes (2)
  1. Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score

    WOMAC is a scale to assess disease-related functional status and disability. It consists of three parts with 24 simple questions in total. Five questions are related to pain (WOMAC-A), two questions to morning stiffness (WOMAC-B), and the remaining 17 questions to physical condition (WOMAC-C). Each question is scored using 4-point Likert scale (0= None, 1= Mild, 2= Moderate, 3= Severe, 4= Very severe). Higher scores indicate severe pain, increased stiffness, and functional failure. Minimum score of the scale is 0 and maximum is 100. Higher scores mean worse outcomes.

    Measured: Pre-intervention, Change from baseline WOMAC score at 12th weeks

  2. Six minute walk test

    It is an objective method to evaluate exercise tolerance. It was performed on an unobstructed bare 30 meters (m) floor where every 3 meters were marked. The patients were allowed to complete the test by reducing their walking speed or stopping and getting some rest, if needed. Maximum walking distance (meters) within six min was measured. Higher distance means better outcome.

    Measured: Pre-intervention, Change from baseline six minute walk test at 12th weeks

Questions about this trial

What is this clinical trial studying?

A study testing Ultrasound guided genicular nerve block + exercise treatment and Physical therapy + exercise treatment in people with Knee Osteoarthritis, run by Turkish League Against Rheumatism at 1 site in Turkey (Türkiye).

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 2 inclusion and 10 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 7 Feb 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 Turkey (Türkiye). 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: Pre-intervention, Change from Baseline visual analog scale at 12th weeks). 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 NCT04782401, 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 7 Feb 2022.
