AC Joint Conditions That Can Require Surgery

The acromioclavicular (AC) joint, located at the top of the shoulder where the clavicle (collarbone) meets the acromion (part of the scapula), plays a crucial role in shoulder stability and movement. When the AC joint is injured or affected by degenerative conditions, it can cause significant pain and dysfunction, sometimes requiring surgical intervention. At Robotic Hip and Knee Replacement LA, we provide expert care for AC joint conditions that may necessitate surgery.

Common AC Joint Conditions

Several conditions can impact the AC joint, leading to pain and limited shoulder function. The most common issues that may require surgical treatment include:

• AC Joint Arthritis: Osteoarthritis can develop over time due to wear and tear, leading to joint pain, stiffness, and swelling. Studies suggest that AC joint arthritis is present in up to 30% of adults over the age of 60.
• AC Joint Separation: This condition occurs when the ligaments that stabilize the joint are stretched or torn, often due to a direct fall on the shoulder. AC joint separations account for nearly 40% of shoulder injuries in contact sports.
• Fractures: Trauma, such as car accidents or sports injuries, can lead to fractures of the clavicle or acromion, which may require surgical intervention if the bones are severely displaced.
• Chronic Instability: Recurrent dislocations or persistent pain after an initial injury may indicate an unstable AC joint that requires surgical stabilization.

Symptoms Indicating the Need for Surgery

While conservative treatments such as physical therapy, medication, and corticosteroid injections can alleviate symptoms for many AC joint conditions, surgery may be necessary if symptoms persist or worsen. Key signs that may indicate the need for surgical intervention include:

• Persistent pain that limits daily activities
• Shoulder weakness or reduced range of motion
• Visible deformity of the shoulder joint
• Pain that does not improve with non-surgical treatments

Surgical Treatment Options

If non-surgical methods fail to provide relief, several surgical procedures may be considered to restore function and alleviate pain in the AC joint. Common surgical options include:

• Arthroscopic Surgery: A minimally invasive technique that allows surgeons to remove damaged tissue and smooth out the joint.
• AC Joint Reconstruction: In cases of severe separation or instability, reconstruction using grafts or synthetic materials may be performed.
• Distal Clavicle Resection: Also known as the Mumford procedure, this involves removing a small portion of the clavicle to relieve pain caused by arthritis or impingement.

Recovery after AC joint surgery typically involves a period of immobilization followed by physical therapy to restore strength and range of motion. Most patients can expect to return to normal activities within 3 to 6 months, depending on the procedure performed and their overall health.
