AC Joint Reconstruction
What Is AC Joint Reconstruction?
AC joint reconstruction is a surgical procedure used to restore stability to the acromioclavicular (AC) joint, which is located where the collarbone (clavicle) meets the shoulder blade (acromion). This joint is stabilized by strong ligaments that can be torn during a shoulder separation.
When these ligaments are severely damaged, the collarbone can shift upward, causing pain, weakness, and a visible bump on the shoulder. AC joint reconstruction rebuilds or replaces the damaged ligaments to restore normal alignment and stability.
At OIBortho, our physicians evaluate and treat AC joint injuries and shoulder instability for patients throughout Middlesex, Monmouth, and Ocean Counties.
When Is AC Joint Reconstruction Needed?
This procedure is typically recommended for more severe AC joint injuries that do not improve with non-surgical treatment.
It may be considered for:
- High-grade AC joint separations (Grade III–VI)
- Persistent shoulder pain after injury
- Visible deformity with functional limitations
- Chronic instability of the AC joint
- Failure of conservative treatment (sling, therapy)
- High-demand athletes or manual laborers
Symptoms of Severe AC Joint Injury
Patients who may require reconstruction often experience:
- Pain at the top of the shoulder
- Visible bump or deformity
- Shoulder weakness
- Pain with lifting or overhead movement
- Difficulty performing physical work or sports
- Chronic discomfort after initial injury
- Instability or abnormal shoulder movement
Causes of AC Joint Injury
AC joint injuries requiring reconstruction are most often caused by trauma.
Common causes include:
- Falling directly onto the shoulder
- Sports injuries (football, hockey, cycling, wrestling)
- Motor vehicle accidents
- Direct impact to the shoulder
- High-energy collisions
Severe injuries usually involve complete ligament tears.
How AC Joint Reconstruction Works
During AC joint reconstruction:
- Damaged ligaments are identified and removed or repaired
- A tendon graft (from the patient or donor tissue) is used to recreate the ligaments
- The collarbone is repositioned into proper alignment
- The graft is secured to restore stability
- In some cases, hardware or fixation devices are used temporarily
The goal is to restore normal joint position and long-term stability.
Recovery and What to Expect
Recovery depends on injury severity and surgical technique.
Typical recovery may include:
- Sling immobilization for several weeks
- Gradual return to motion under supervision
- Physical therapy to restore strength and stability
- Avoidance of heavy lifting early in recovery
- Return to full activity over several months
Full recovery requires time for graft healing and shoulder rehabilitation.
Risks and Considerations
As with any surgery, risks may include:
- Infection
- Failure of graft healing
- Persistent pain or stiffness
- Loss of reduction (recurrent separation)
- Hardware irritation or complications
- Nerve irritation (rare)
Your physician will review risks and expected outcomes before surgery.

What is AC joint reconstruction?
It is surgery that restores stability to a severely injured AC joint by reconstructing damaged ligaments.
When is it needed?
It is typically used for severe shoulder separations or chronic instability.
How long is recovery?
Recovery usually takes several months with physical therapy.
Will the bump on my shoulder go away?
Reconstruction helps restore alignment, but some residual prominence may remain in certain cases.
Can I return to sports?
Yes, but only after full healing and rehabilitation.
Is surgery always required?
No, many AC joint injuries heal without surgery, but severe cases may need reconstruction.
