Diagnostic Value of Weight Bearing CT for Detecting Meniscal Tears

May 15, 2024 updated by: Neil Segal, MD, MS, University of Kansas Medical Center

Comparison of Weight Bearing CT Arthrography With MRI for Detection of Knee Meniscal and Cartilage Lesions.

This observational study will compare the clinical value of weight-bearing CT arthrography (WBCTa) with that for MRI in evaluating meniscal and cartilage lesions of the knee joint. The MRI Osteoarthritis Knee Score (MOAKS) and modified MOAKS for WBCTa will be used to compare findings between MRI and WBCTa of the knee while comparing with surgical measurements using the ICRS scoring system.

The study hypothesis is that meniscal and cartilage lesions may be missed by non-weight-bearing MRI, but detected by WBCTa.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Study Objectives:

Aim 1 Establish the accuracy of WBCTa and MRI for diagnosing knee cartilage and meniscal lesions in both surgical and non-surgical participants.

Hypothesis 1: Pre-operative cartilage and meniscal scoring on WBCTa is more accurate than MRI, in comparison with arthroscopic assessment.

Aim 2 Establish the accuracy of WBCTa for detecting persistent and recurrent meniscal root and radial tears not detected by MRI 6 months after meniscal repair (defined by diastasis of the repair or meniscal extrusion ≥3mm).

Hypothesis 2: Six months following meniscal repair, WBCTa detects persistent and recurrent meniscal root and radial re-tears not detected by MRI.

Study Type and Design: This cross-sectional, observational study will compare WBCTa with MRI to evaluate rate of detection of meniscal and cartilage lesions. The inter-rater reliability of WBCTa readings also will be assessed.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 81 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Participants will be recruited from orthopedic clinics as well as other musculoskeletal clinics that request knee MRI. Special efforts will be made to recruit the majority from orthopedic sports medicine clinical practices to include patients who are scheduled for arthroscopic meniscal repair of full-thickness radial tears of the posterior horn or body or root tears of the posterior horn after clinical MRI. There will be no exclusions based on sex or ethnic group.

Description

Inclusion Criteria:

  • Male or female over 18 years of age with a knee MRI acquired in the previous 10 days to evaluate for suspected meniscal or cartilage pathology.
  • Body mass index (BMI) ≤ 45 kg/m2
  • Ability to stand with support without moving for at least 2 minutes.

Exclusion Criteria:

  • End stage kidney disease
  • Allergic to iodinated contrast material.
  • Pregnancy
  • Skin breakdown or rash at the knee joint which would prevent injection of the contrast.
  • Any clinically significant degree of cognitive impairment or other condition, finding, or psychiatric illness at screening which, in the opinion of the investigator, affects their ability to ambulate to a sufficient degree and could compromise patient safety or interfere with the assessment of the safety of the study injection.
  • Superficial or deep infection in or around the index knee joint or allergy to iodinated contrast media.
  • History of inflammatory arthritis, meniscectomy, or end-stage OA

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
To determine the agreement between weight-bearing CT arthrography (WBCTa) and MRI in evaluation of meniscal tears.
Time Frame: Baseline
Pre-operative cartilage lesion scoring of meniscal lesions on WBCTa (modified MOAKS score) and MRI (modified MOAKS score) will be compared with arthroscopic visual MOAKS scoring of meniscal lesions.
Baseline

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
To determine the agreement between weight-bearing CT arthrography and MRI in evaluation of cartilage lesions.
Time Frame: Baseline
Musculoskeletal radiologists, each with greater than 10 years of experience will assess the morphology of the medial and lateral tibiofemoral cartilage on MRI and WBCTa using the MOAKS scoring system. Area of cartilage damage per subregion will be graded according to the MOAKS classification from 0-3: 0= no cartilage damage, 1=cartilage damage involving <10% of the subregion area, 2= cartilage damage involving 10%-75% of the subregion area and 3=cartilage damage involving >75% of the subregion area. The scores will be compared by dichotomizing into lesion present/absent (primary) and also compared using the full ranges of ordinal scores.
Baseline
To determine the extent to which WBCTa identifies meniscal re-tears or failed repairs 6 months following meniscal root or radial tear surgical repairs
Time Frame: 6 months
Participants who undergo a meniscal repair for radial meniscal tears and posterior root tears will undergo 6-month post-operative MRI and WBCTa and each of these 2 imaging modalities will be assessed for visualization of the presence or absence of a meniscal tear..
