AC Joint Injury Physiotherapy: Understanding the AC Joint Mitcham & Aspendale Gardens, Victoria
The acromioclavicular (AC) joint connects the collarbone (clavicle) to the shoulder blade (scapula), playing a key role in shoulder stability, movement, and load transfer. AC joint injuries, common in athletes, often result from impacts or falls that separate the clavicle from the scapula.
Key Components of the AC Joint
AC Ligament: Maintains joint stability under minor stress.
Coracoclavicular Ligaments: Anchor the clavicle to the scapula to prevent upward displacement.
Joint Capsule: Protects the joint and provides structural support.
This small synovial joint is surrounded by a fluid-filled capsule, enabling smooth motion between the clavicle and scapula, critical for full shoulder function.

FAQ
The acromioclavicular (AC) joint is located at the top of the shoulder, where the collarbone meets the shoulder blade. Injuries to this joint often result from trauma, such as a fall or direct impact, commonly seen in contact sports like rugby or AFL. Overuse from repetitive overhead activities or heavy weightlifting can also lead to AC joint strain or degeneration.
Recovery time depends on the severity of the injury:
- Grade I (mild sprain): 2–4 weeks with physiotherapy.
- Grade II (partial tear): 4–8 weeks with targeted rehabilitation.
- Grade III+ (complete rupture): 12–16 weeks or longer, often requiring surgery followed by physiotherapy. Your physiotherapist will provide a tailored recovery timeline based on your specific condition.
No, surgery is typically only required for severe injuries (Grade III or higher) where the joint is significantly displaced or unstable. Most mild to moderate injuries can be effectively managed with physiotherapy, focusing on pain relief, restoring mobility, and strengthening the joint.
