Shoulder pain can be a debilitating experience, and when it’s linked to AC joint arthritis, it can significantly impact your daily life. AC (acromioclavicular) joint arthritis is a common cause of shoulder discomfort, especially in individuals who engage in repetitive overhead movements or sports activities. This condition can affect people of all ages and backgrounds, making it essential to gain a thorough understanding of its causes, symptoms, and effective management strategies. In this blog, we will delve into the world of AC joint arthritis, exploring its origins, the signs that might indicate its presence, and the various options available for relief and improved quality of life. So, let’s get started!

What is AC Joint Arthritis?
AC joint arthritis, or acromioclavicular joint arthritis, refers to the degeneration of the acromioclavicular joint in the shoulder. The acromioclavicular joint is located at the top of the shoulder, where the acromion (a part of the scapula or shoulder blade) meets the clavicle (collarbone). This joint is responsible for various shoulder movements and is crucial for proper shoulder function.
Arthritis in the AC joint occurs when the cartilage that covers the joint surfaces starts to wear down or become damaged. Cartilage is essential for smooth joint movement, and its deterioration can result in pain, inflammation, and reduced mobility. AC joint arthritis is typically characterized by symptoms like:
- Pain: Individuals with AC joint arthritis often experience pain at the top of the shoulder. The pain can vary in intensity and may worsen with activities that involve lifting the arm or moving the shoulder.
- Swelling: Inflammation of the AC joint can lead to swelling or tenderness in the shoulder area.
- Limited Range of Motion: As the arthritis progresses, the range of motion in the shoulder may become restricted, making it challenging to perform overhead movements or certain activities.
- Crepitus: Some people with AC joint arthritis may hear or feel a grinding or popping sensation in the shoulder when moving it.
- Weakness: Muscle weakness around the shoulder can occur due to pain and limited mobility.
AC joint arthritis can develop due to various factors, including aging, prior shoulder injuries, overuse, or repetitive strain on the joint. It can also be associated with other shoulder conditions.
Causes of AC Joint Arthritis
Understanding the underlying causes of AC joint arthritis can help individuals manage the condition effectively.
- Age-Related Wear and Tear: The most common cause of AC joint arthritis is the natural aging process. Over time, the cartilage that covers the joint surfaces can deteriorate, leading to friction and inflammation. This wear and tear is more likely to occur in individuals over the age of 50.
- Prior Shoulder Injuries: A history of shoulder injuries or trauma can contribute to the development of AC joint arthritis. Injuries such as dislocations, fractures, or repeated shoulder separations can damage the joint’s cartilage and increase the risk of arthritis.
- Overuse or Repetitive Strain: Activities that involve repetitive overhead arm movements, such as weightlifting, throwing, or certain sports, can strain the AC joint. Over time, this repetitive stress may lead to joint inflammation and arthritis.
- Ligament Sprains: Injuries to the ligaments supporting the AC joint, often caused by falls or direct blows to the shoulder, can disrupt the joint’s stability. Instability in the joint can accelerate the degeneration of the cartilage.
- Occupational Factors: Certain occupations that require heavy lifting or overhead work, such as construction or manual labor, can increase the risk of AC joint arthritis due to continuous stress on the joint.
- Genetic Predisposition: Some individuals may have a genetic predisposition to joint problems, including AC joint arthritis. Family history can play a role in the development of this condition.
- Inflammatory Conditions: Inflammatory joint diseases like rheumatoid arthritis or ankylosing spondylitis can affect the AC joint, leading to inflammation and arthritis.
- Unresolved Shoulder Injuries: Failure to adequately treat and rehabilitate previous shoulder injuries can leave the joint vulnerable to degeneration and arthritis.
- Infection or Septic Arthritis: Although rare, bacterial infections can affect the AC joint, causing inflammation and potentially leading to arthritis if not treated promptly.
Understanding the specific cause of AC joint arthritis is essential for developing an appropriate treatment plan. Early diagnosis and treatment can help individuals with AC joint arthritis manage their symptoms effectively and maintain a good quality of life.
