If you’ve recently been diagnosed with Symptomatic AC joint (degenerative joint disease or synovitis), you may be wondering exactly what it means and what options are available to relieve your shoulder pain.
In this article, we’ll guide you through the essentials — from recognizing symptoms to understanding treatment options, including the highly effective surgical procedure called Arthroscopic Distal Clavicle Resection. Our goal is to give you a clear, reassuring explanation so you can make informed decisions about your shoulder health.
General Points
What is Symptomatic AC Joint (Degenerative Joint Disease or Synovitis)?
The AC (acromioclavicular) joint is located at the top of your shoulder, where the collarbone (clavicle) meets the highest point of the shoulder blade (acromion). Over time or after repetitive stress, this joint can develop degenerative changes, leading to pain, stiffness, and inflammation.
When these changes cause noticeable discomfort and functional limitations, we call it Symptomatic AC joint disease. In some cases, inflammation of the joint lining, known as synovitis, can also develop, worsening pain and reducing shoulder mobility. Early recognition and treatment are important to prevent chronic discomfort and maintain an active lifestyle.

Symptoms of Symptomatic AC Joint Disease
Patients with symptomatic AC joint problems often describe a combination of the following:
- Pain at the top of the shoulder — especially when lifting your arm overhead or reaching across your body.
- Tenderness directly over the AC joint — often easy to locate with gentle touch.
- Swelling or warmth — indicating active inflammation.
- Reduced range of motion — difficulty raising your arm fully or performing everyday activities like putting on a shirt.
- Clicking or popping sensations — sometimes accompanied by discomfort.
- Nighttime pain — making it difficult to sleep on the affected side.
Symptoms can vary in intensity and may gradually worsen over time, especially if the joint is subjected to repetitive strain or if degenerative changes progress.
How is Symptomatic AC Joint Diagnosed?
A thorough evaluation by an orthopedic specialist is essential to confirm the diagnosis and rule out other shoulder conditions. Diagnosis typically involves:
Physical Examination
- The doctor will palpate the AC joint to locate tenderness.
- Specific arm movements may reproduce pain, helping to pinpoint the affected area.
- Strength and shoulder mobility tests assess the impact of the condition on function.
Imaging Studies
- X-rays: Help detect bone spurs, joint narrowing, or degenerative changes.
- MRI: Provides detailed images of soft tissues, including synovium, cartilage, and any associated inflammation.
- Ultrasound: Sometimes used to evaluate inflammation in real time.
With these tools, your orthopedic specialist can accurately identify the source of pain and plan the most effective treatment.
Treatment Options for Symptomatic AC Joint
Treatment depends on the severity of symptoms, lifestyle demands, and response to non-surgical approaches. The options fall into two main categories: non-surgical and surgical.
Non-Surgical Approaches
For many patients, conservative management provides meaningful relief:
- Rest and activity modification: Avoid movements that trigger pain.
- Anti-inflammatory medications: Over-the-counter NSAIDs can reduce pain and swelling.
- Physical therapy: Strengthening surrounding shoulder muscles and improving range of motion can ease pressure on the AC joint.
- Corticosteroid injections: Can provide temporary pain relief, especially if inflammation is significant.
Non-surgical treatment is often effective for mild to moderate symptoms. However, if pain persists or functional limitations interfere with daily life, surgical intervention may be recommended.
Arthroscopic Distal Clavicle Resection: A Surgical Solution
When conservative measures aren’t enough, Arthroscopic Distal Clavicle Resection is the gold-standard surgical option for symptomatic AC joint disease.
What is Arthroscopic Distal Clavicle Resection?
This minimally invasive procedure involves removing a small portion of the end of the collarbone (distal clavicle) to relieve pressure on the AC joint and reduce pain. By doing so:
- Bone-on-bone contact is eliminated.
- Inflammation and mechanical irritation are minimized.
- Joint function is restored, allowing smoother shoulder movement.
How the Procedure is Performed
- Small incisions (portals) are made around the shoulder.
- A tiny camera (arthroscope) allows the surgeon to see inside the joint.
- Specialized instruments remove the damaged end of the clavicle while preserving surrounding tissues.
- The procedure is typically done on an outpatient basis, meaning you can go home the same day.
Benefits of Arthroscopic Distal Clavicle Resection
- Minimally invasive: Less pain, smaller scars, and faster recovery compared to traditional open surgery.
- High success rates: Studies show over 90% of patients experience significant pain relief and improved function.
- Durable results: Long-term outcomes are excellent, with most patients returning to normal activities and even sports.
- Low risk of complications: The arthroscopic approach reduces the risk of infection and preserves surrounding structures.
Take Action for Lasting Shoulder Relief
If you’re struggling with Symptomatic AC joint (degenerative joint disease or synovitis), it’s important to consult an orthopedic specialist promptly. Early evaluation allows for the best combination of non-surgical and surgical options tailored to your needs.
For patients who require surgery, Arthroscopic Distal Clavicle Resection is a safe, effective, and minimally invasive solution that provides long-lasting pain relief and restores shoulder function. With expert care and proper rehabilitation, you can get back to the activities you love — without the nagging discomfort at the top of your shoulder.
