ACJ Reconstruction Explained: When is it Needed and What to Expect

Overview

The acromioclavicular joint (ACJ) is where your collarbone meets your shoulder blade. This joint can become unstable due to a high-energy injury, such as a fall or collision. In these cases, ACJ reconstruction surgery might be necessary to restore stability and alleviate pain.

Why is ACJ Reconstruction performed?

ACJ reconstruction surgery is typically recommended only in cases of severe ACJ instability. For less serious injuries, other less invasive treatments, such as physiotherapy, are usually preferred.

Here are some signs that ACJ reconstruction surgery might be necessary:

  • Significant pain in the shoulder, especially when lifting your arm.
  • A noticeable bump or deformity at the ACJ.
  • Difficulty performing daily activities due to shoulder instability.

What to expect during surgery:

ACJ reconstruction surgery can be performed using either open or arthroscopic (keyhole) techniques. Open surgery is generally preferred as it allows for better repair of the surrounding muscles and fascia.

During the surgery, your surgeon will use either:

  • A section of your own ligament taken from the front of your shoulder (the coracoacromial ligament)
  • An artificial ligament (such as Lockdown- Surgilig) These materials are used to create a new ligament and stabilize the ACJ joint. In severe cases, a temporary plate (Hook Plate) might also be used to hold the joint in place while the ligament heals. This plate is usually removed in a second surgery.

Recovery after surgery

  • The surgery is performed under general anesthesia.
  • You will likely have a scar of 5-7 cm along the top of your shoulder.
  • Your arm will need to be immobilized in a sling for at least 4-6 weeks to allow the ligament to heal properly.
  • Physical therapy will be crucial to regain movement and strength in your shoulder.

Here are some additional details to remember

  • ACJ reconstruction is a relatively common procedure with good long-term results.
  • It is important to follow your doctor’s instructions carefully during recovery to ensure optimal healing.
  • If you experience any concerning symptoms after surgery, such as increased pain, swelling, or fever, consult your doctor immediately.
