Steroid and Local Anaesthetic Injections

Overview

Steroid injections, often combined with a local anaesthetic, are used to rapidly reduce pain and inflammation in the knee joint caused by osteoarthritis or acute flare-ups. The steroid component acts to suppress inflammation, while the anaesthetic delivers immediate pain relief.

Mechanism of Action

Corticosteroids decrease inflammatory mediators within the joint, cushioning the impact of osteoarthritis and improving comfort. The local anaesthetic numbs the area during and immediately after the injection, boosting patient comfort.

Efficacy

Pain relief often occurs within days and can last from several weeks to a few months, but the effect diminishes over time with repeat injections.

Safety and Side Effects

While generally safe, repeated injections may cause cartilage damage, weakening of joint structures, and increase the risk of joint infection. Short-term side effects include local discomfort and mild swelling.

Other injection options: Because repeat steroid injections are limited, Mr Chauhan often discusses the other knee injection treatments available: Arthrosamid hydrogel injections for longer-lasting relief, hyaluronic acid (Ostenil) to lubricate the joint, and platelet-rich plasma (PRP). Steroid injections are also used, often under ultrasound guidance, in hand and wrist conditions. To discuss which is right for you, book a consultation or review the treatment fees.
