Typical symptoms of AC joint arthritis

AC joint arthritis often makes itself known through pain right at the top of the shoulder. This is especially noticeable when lifting the arm above the head, bringing it across the chest, or carrying heavy objects. Some people also notice an uncomfortable feeling of pressure, occasional grinding, or mild swelling in the area. In more advanced cases, the shoulder can hurt even at rest, for example at night when lying on the affected side.

Is AC joint arthritis serious?

For many people, the diagnosis sounds worrying at first. Questions often come up such as: Will I need an operation? Will the shoulder become permanently stiff? How much will it affect daily life? In fact, AC joint arthritis is a very common form of wear and tear, especially from middle age onwards. Many people have changes in the AC joint without feeling anything at all. It only becomes a problem when the arthritis starts causing symptoms.

In most cases, the shoulder continues to work well despite arthritis. Pain usually only occurs with certain movements or activities. Complete stiffening or lasting severe restriction is rare. That said, the symptoms can be bothersome, especially if they disturb sleep or make everyday tasks difficult.

Causes and risk factors

Wear and tear is the most common cause of AC joint arthritis. As we age, the cartilage gradually wears down. People who regularly lift heavy loads, do a lot of sport involving overhead movements (such as tennis, volleyball, or weightlifting), or who have had a previous shoulder injury are more commonly affected. Repeated minor injuries, for example from falls or knocks, can also contribute to its development.

How is AC joint arthritis diagnosed?

Diagnosis is usually made through a combination of a conversation, a physical examination, and imaging. A typical sign is tenderness directly over the joint, as well as pain with certain arm movements. An X-ray shows whether the joint space has narrowed or whether the bone has already changed. Sometimes an ultrasound or an MRI scan is also used to rule out other causes of the symptoms.

Treatment options for AC joint arthritis

Many people wonder whether an operation is necessary. In most cases, however, arthritis can be managed well with non-surgical approaches. This means that rest, targeted physiotherapy, and pain-relieving medication are the main focus. Cold therapy or anti-inflammatory gels often provide relief. A cortisone injection directly into the joint can temporarily ease severe symptoms.

Only if these measures are not enough and the pain is consistently affecting daily life will surgery be considered. The procedure usually involves removing a small part of the collarbone so that the painful friction is eliminated. The operation is generally minimally invasive, meaning small incisions and a short recovery time.

What helps in daily life?

People with AC joint arthritis can do quite a lot in everyday life to ease their symptoms. It helps to avoid overhead activities and carrying heavy loads. Targeted exercises for the shoulder muscles, as shown in physiotherapy, stabilise the joint and reduce strain on the irritated structures. Good posture and an ergonomic working position can also help protect the shoulder. During a flare-up, it is a good idea to cool the shoulder and rest it for a few days.

Outlook and progression

Most people with AC joint arthritis manage well with the right approach. Symptoms can often be reduced significantly, and the shoulder usually stays mobile. Only rarely does arthritis progress to the point where surgery becomes necessary. Paying attention to early warning signs and avoiding long-term overload can often slow the progression of changes.

A diagnosis of AC joint arthritis is no reason to panic. With the right management, a little patience, and targeted support, the shoulder can continue to serve you well in everyday life.
