Dr Marcus Chia - Shoulder Surgeon
Learn about AC joint arthritis causes and treatment options.
AC joint arthritis is a type of shoulder arthritis that affects the acromioclavicular joint or AC joint. The AC joint is in the shoulder, where the clavicle (collarbone) and scapula (shoulder blade) meet. Between these bones, there is cartilage which is tissue that allows the bones to move on each other. Over time, with wear and tear, this tissue becomes thin or disappears.
AC joint arthritis is one of the most common AC joint conditions, along with fractures and separations. There are different types of AC joint arthritis, including:

To determine if your shoulder injury is AC joint arthritis, Dr Chia will take a detailed medical history and perform a physical examination. He will check your shoulder and may ask you to take an X-ray, CT or MRI scan to rule out other conditions.
If you are diagnosed with AC joint arthritis, Dr Chia will discuss your treatment options and next steps.
There are both surgical and nonsurgical treatment options for AC joint arthritis.
Nonsurgical treatment options include:
Dr Chia will develop a personalised treatment plan with exercises and steps to help you regain your motion.
If these nonsurgical options can’t relieve your AC joint arthritis pain, Dr Chia may recommend surgical treatment options.
Surgery for AC joint arthritis involves removing a portion of the end of the clavicle, preventing the damaged joint surfaces from touching. Around 10mm of the collarbone.
Dr Chia will perform the surgery using a series of small incisions (cuts) which is known as keyhole surgery. The surgery usually takes around one hour.
You should be able to go home on the day of the surgery, and you will need to wear a sling for a few days. After about a week you can begin gentle recovery and movement exercises. You should regain full motion in around four to six weeks after your surgery.
You will have follow-up with a physiotherapist who can assist your healing and give you gentle exercises to gradually rehabilitate your shoulder and help your recovery.
