NCT06527235

Brief 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.

Study Arms (2)

ultrasound-guided betamethasone infiltration of the meniscal wall

EXPERIMENTAL

patients allocated to the experimental group will receive a single betamethasone infiltration (1mL) of the meniscal wall under ultrasound guidance.

Drug: ultrasound-guided betamethasone infiltration of the meniscal wall

ultrasound-guided physiological serum infiltration of the meniscal wall

PLACEBO COMPARATOR

patients allocated to the control group will receive a single placebo infiltration of isotonic saline (1mL) of the meniscal wall under ultrasound guidance.

Drug: ultrasound-guided isotonic saline (placebo) infiltration of the meniscal wall

Interventions

The perimeniscal injections will be guided by ultrasound with an 18 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 isotonic saline 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 Once the needle touches the meniscus wall, it will be withdrawn 1 mm, and a 1-ml injection of betamethasone into the meniscus wall will be performed.

ultrasound-guided physiological serum 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.
