Meniscal INfiltration of Corticosteroid Guided With Ultra Sonography

Efficacy of Ultrasound-monitored Meniscal Wall Betamethasone Infiltration on Pain in Relation to Degenerative Meniscal Injury: a Randomized, Double-blind, Placebo-controlled Multicenter Trial.

Sponsor

University Hospital, Toulouse

Enrollment

152 participants

Start Date

Mar 6, 2025

Study Type

INTERVENTIONAL

Conditions

Meniscus Lesion

Summary

The value of corticosteroid infiltration of the meniscus wall in the therapeutic strategy is not clearly defined: the data in the literature on the effectiveness of corticosteroid infiltration are heterogeneous and of low level of proof. We hypothesize that corticosteroid infiltration of the meniscal wall under ultrasound control would be effective for rapid relief of degenerative meniscal pain. The main objective is to evaluate the efficacy of ultrasound-guided meniscal wall infiltration of betamethasone versus ultrasound-guided meniscal wall infiltration of placebo, at 1 month, on meniscal pain in the treatment of meniscal pain of degenerative origin in adult.

Eligibility

Min Age: 18 Years

Plain Language Summary

Simplified for easier understanding

This clinical trial is studying a drug called ultrasound-guided betamethasone infiltration of the meniscal wall and a drug called ultrasound-guided isotonic saline (placebo) infiltration of the meniscal wall for people with meniscus lesion. The study is currently recruiting participants at 1 location.

Interventions

DRUGultrasound-guided betamethasone infiltration of the meniscal wall

The perimeniscal injections will be guided by ultrasound with an 18 megahertz (MHz) linear probe under strict aseptic conditions. Doppler will be systematically used before the injection to identify the medial or lateral inferior geniculate artery. The first step will consist of local anesthesia with 2 ml of lidocaine injected into the subcutaneous tissues and close to the meniscus wall using a 25-gauge needle. Using an in-plane approach, a 21-gauge needle will be positioned under ultrasound guidance in the medial or lateral wall of the meniscus. Once the needle touches the meniscus wall, it will be withdrawn 1 mm, and a 1-ml injection of betamethasone into the meniscus wall will be performed.
