Do I need to have surgery for frozen shoulder?

Most cases of frozen shoulder (adhesive capsulitis) improve with non-surgical treatments such as physical therapy, non-invasive therapies, and medications. However, if your shoulder remains severely stiff or painful for many months despite conservative care, surgery may be considered to restore motion.

At The Pain Relief Clinic, we emphasize non-invasive approaches first, and only refer patients for surgery when absolutely necessary.

What are the different types of frozen shoulder surgery?

The two most common procedures include:

1. Shoulder Manipulation Under Anesthesia (MUA)
   • The patient is sedated, and the shoulder is gently moved to break up adhesions.
   • No incision is made.
   • Often combined with a steroid injection.
2. Arthroscopic Capsular Release
   • A minimally invasive procedure using a small camera and instruments to cut tight portions of the joint capsule.
   • Allows more precise treatment with less trauma than open surgery.

These procedures are typically performed in a hospital setting and followed by aggressive rehabilitation to maintain shoulder movement.

What is the recovery time for frozen shoulder surgery?

Recovery varies depending on the procedure and individual healing.

• MUA: Most patients regain significant motion in 1–2 months with therapy.
• Arthroscopic surgery: May require 6–12 weeks or longer of structured physiotherapy.

Early and consistent rehabilitation is critical to achieving the best outcome.

What are the risks of frozen shoulder surgery?

Although generally safe, risks include:

• Persistent stiffness or pain
• Infection (rare)
• Nerve or blood vessel injury
• Reaction to anesthesia
• Re-adhesion of tissue if rehab is not followed closely

Careful patient selection and proper post-op management reduce these risks.

What are the benefits of frozen shoulder surgery?

When successful, surgery can:

• Improve range of motion
• Relieve pain
• Restore daily function faster than waiting for spontaneous recovery
• Reduce long-term disability in severe cases

However, not all patients require surgery. We help you explore all non-invasive options before considering surgical referral.

Is manipulation under anesthesia an option for frozen shoulder?

Yes. MUA can be helpful in carefully selected patients who:

• Have persistent stiffness despite months of therapy
• Do not have severe underlying joint damage
• Are medically fit for sedation

At The Pain Relief Clinic, we assess whether patients are suitable for MUA or referral for surgical intervention, always aiming for the least invasive, safest option.
