AC Joint Stabilisation and Reconstruction
Overview
The acromioclavicular, or AC, joint sits at the top of the shoulder where the collarbone meets the shoulder blade. Injury to this joint can occur after a fall, tackle or direct impact onto the shoulder. Some AC joint injuries settle without surgery, while higher-grade injuries may leave persistent pain, deformity, weakness or instability.
AC joint stabilisation and reconstruction aims to restore alignment and stability when the joint remains symptomatic or unstable despite appropriate non-operative treatment.
Who may benefit from AC joint surgery?
Surgery may be considered for high-grade AC joint separations, ongoing instability, painful deformity, failed non-operative treatment, or persistent symptoms in patients with high work or sporting demands.
The decision is based on the grade of injury, symptoms, shoulder function, timing from injury and patient goals.
What does the procedure involve?
The operation stabilises the collarbone relative to the shoulder blade. Depending on the injury and timing, this may involve suture-button fixation, ligament reconstruction, graft augmentation or a combination of techniques.
In chronic injuries, reconstruction is often needed because the original ligaments may no longer heal reliably. The aim is to restore a stable platform for shoulder function.
Recovery after AC joint reconstruction
Recovery is protective in the early phase. A sling is used while the reconstruction begins to heal, then motion is gradually restored. Strengthening and return to overhead loading or contact sport are introduced later.
Rehabilitation protocol
You will receive an AC joint stabilisation or reconstruction protocol outlining sling use, movement limits and progression to strengthening.
FAQs
Do all AC joint separations need surgery?
No. Many lower-grade injuries recover well without surgery. Surgery is considered for selected high-grade or persistently symptomatic injuries.
Will the bump disappear after surgery?
The aim is to improve alignment and stability, but some residual prominence can remain.
How long will I wear a sling?
Sling duration depends on the reconstruction and tissue quality, but protection is usually required for several weeks.
When can I return to gym training?
Lower-body and non-shoulder training may resume earlier. Pressing, pulling and overhead loading return gradually once cleared.
Can AC joint instability recur?
Loss of reduction or recurrent symptoms can occur, especially with early overload or further injury.
