A gentle needle wash-out of the joint — often combined with a regenerative injection — and one of the quickest treatments we offer.
Sometimes the joint simply needs flushing out — no cuts, and a rapid recovery.
In arthrocentesis, two fine needles are placed into the upper joint space and sterile fluid is flushed through to wash out the inflammatory chemicals and debris that drive pain, freeing up a stiff joint. It is often followed by an injection of hyaluronic acid and/or platelet-rich plasma (PRP). It can be done under local anaesthetic, sedation, or a short general anaesthetic, usually takes 20–30 minutes, and leaves no cuts to stitch.
Adding PRP aims to calm inflammation and support the joint. In a recent randomised trial, double-puncture arthrocentesis with hyaluronic acid and PRP achieved markedly better 12-month results than hyaluronic acid alone, with far fewer patients needing further treatment. Mr Komath has also published on regenerative approaches in TMJ disorders.
Beyond a first-line procedure
For patients for whom full arthroscopy is not the right step — clinically or financially — arthrocentesis (± PRP) is a genuinely effective, gentler and lower-cost procedure. It widens who we can help, without lowering standards.
For advanced cases awaiting joint replacement, arthrocentesis can give meaningful symptom relief in the interim — a temporising measure, described honestly as such, never a substitute for definitive surgery.
Recovery is quick. Expect mild soreness and a little swelling for a day or two; most people return to normal activities the next day. Keep to a soft diet for a few days and avoid opening very wide at first. If PRP or hyaluronic acid was used, the benefit usually builds over the following weeks. Full arthrocentesis aftercare →
This is the lowest-risk of our joint procedures. You may have mild soreness, swelling or bruising. Uncommonly there can be temporary numbness or facial-muscle weakness near the joint, infection, or a reaction to the injected substance. Symptoms occasionally flare briefly before improving, and a repeat treatment may be needed. If sedation or a general anaesthetic is used, the usual anaesthetic precautions apply.
Arrange a consultation and we'll assess your joint and advise on the gentlest effective option.
