About this study

Clinical-noninvasive recording of sounds from the knees through a brief loaded range of motion. Description in phase 1 analytic but descriptive as well in phase 2. No samples other than a sound recording. The device is known microphone attached to the skin of the knee with elastic material. Sound recorded and analyzed on a lap top computer with Adobe software.

Read the detailed description

There is a need for a less expensive and more universally available screening device for the knee, and other joint pathology. The equipment used for ultrasound is much less expensive and cumbersome than that of an x-ray or magnetic resonance imaging. The equipment we will use for the analysis of sound produced by the body itself is an order of magnitude less expensive than ultrasound; such as a laptop computer with currently available software and an inexpensive transducer. Analysis of sound has proved useful in Pulmonology and Cardiology. We believe sound analysis will provide a useful yet inexpensive tool for primary care physicians as well as musculoskeletal specialists.

Phase 1: Establish the normal sound patterns emanating from the uninjured knee; we will look for the influence of age, height and weight.

Phase 2: To record and analyze the preoperative sound patterns from the knees with pathology, known by MRI and arthroscopy, then compare them with the normal sounds from Phase 1.

What is being measured

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

  1. Analysis of Joint Sounds in the Diagnosis of Knee Disorders

    Phase 1: Analysis will be carried out on the recording from apparently normal knees, sounds are amplification, wave form and filtering. Effects of age, height and weight. Phase 2: analysis of sound will br carried out by a researcher blinded to the MRI and arthroscopic pathology, Then, comparison of the abnormal sounds to the pathology found on the MRI and Arthroscopy to look for correlations.

    Measured: 1 -2 years

Questions about this trial

What is this clinical trial studying?

An observational study of Arthritis of Knee and Normal Knee, run by Loma Linda University.

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 6 inclusion and 4 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: withdrawn, as of the sponsor's last update on 4 Jun 2021. 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 was withdrawn before enrolling participants, so there are no results.

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?

Analysis of Joint Sounds in the Diagnosis of Knee Disorders (time frame: 1 -2 years). 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 NCT02294045, 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 4 Jun 2021.
