Adductor canal block versus intra-articular steroid and lidocaine injection for knee osteoarthritis: a randomized controlled study.

ABSTRACT:

Background

This study aimed to assess the efficacy of the adductor canal block (ACB) in comparison to intra-articular steroid-lidocaine injection (IASLI) to control chronic knee osteoarthritis (KOA) pain.

Methods

A randomized, single-blinded trial in an outpatient rehabilitation clinic recruiting chronic KOA with pain ≥ 6 months over one year. Following randomization, subjects received either a single ACB or IASLI under ultrasound guidance. Numerical rating scale (NRS) scores for pain, and Knee Injury and Osteoarthritis Outcome Scores (KOOS) were recorded at baseline, 1 hour, 1 month, and 3 months postinjection.

Results

Sixty-six knees were recruited; 2 were lost to follow-up. Age was normally distributed (P = 0.463), with more female subjects in both arms (
