A comparative study of the efficacy of intra-articular injection of 2% lignocaine in the treatment of osteoarthritis knee in contrast to the injection of normal saline

Abstract

Osteoarthritis of the knee is a commonly occurring disorder in the elderly population worldwide. It is usually treated with first-line therapies like life-style modification, analgesics, braces, and physiotherapy. Increasingly second-line treatments – intra-articular platelet-rich plasma, hyaluronic acid, and lignocaine are being offered. We compared 50 knee joints of 25 patients of advanced knee osteoarthritis by treating 25 knee joints with intra-articular 2% lignocaine and other 25 knee joints (allocated randomly) with intra-articular saline injection as a placebo and using NPRS scale and WOMAC SCALE for results.
