Frozen Shoulder Surgery: Proven Treatments & Expert Insights

Frozen shoulder, also known as adhesive capsulitis, is a painful condition that causes shoulder stiffness, pain, and reduced mobility. It can significantly impact daily activities such as dressing, reaching overhead, or sleeping comfortably. While many cases improve with conservative techniques such as physical therapy, corticosteroid injections, and activity modification, some people require frozen shoulder surgery for long-term relief.

This guide explores everything you need to know about surgery for a frozen shoulder, including its causes, symptoms, non-surgical and surgical treatments, and what to expect during frozen shoulder surgery recovery. We’ll also discuss expert insights from orthopedic specialists and key rehabilitation steps to ensure long-term outcomes.

Understanding Frozen Shoulder (Adhesive Capsulitis)

Frozen shoulder is a debilitating condition that affects the shoulder joint, leading to stiffness, pain, and a significant loss of range of motion. It can develop gradually over time, often without a clear cause, and severely limit everyday activities such as reaching, lifting, or even getting dressed. Understanding the causes, risk factors, and progression of frozen shoulder is crucial in determining the best course of treatment—whether through conservative techniques or, in severe cases, frozen shoulder surgery.

What is Frozen Shoulder?

Frozen shoulder, or adhesive capsulitis, occurs when the shoulder capsule thickens and tightens, restricting movement and causing shoulder stiffness. The shoulder joint contains synovial fluid, which lubricates the joint, but in a frozen shoulder, this fluid decreases, leading to shoulder immobility and inflammation. The condition commonly affects individuals who have had prolonged immobilization due to injury, surgery, or underlying health conditions such as diabetes, hypothyroidism, hyperthyroidism, cardiovascular disease, and Parkinson’s disease. Early diagnosis is key to preventing severe shoulder contracture. Expert radiologists often use magnetic resonance imaging (MRI), ultrasound, or X-ray to rule out other conditions like rotator cuff injury, calcific tendonitis, or shoulder arthritis.

Causes and Risk Factors

While the exact cause of frozen shoulder remains unclear, several risk factors contribute to its development. Diabetes is one of the most significant factors, as individuals with poor glucose control are more likely to experience adhesive capsulitis due to its impact on connective tissues. Similarly, thyroid conditions, including hypothyroidism and hyperthyroidism, can lead to increased shoulder inflammation, further restricting mobility. People with a history of cardiovascular disease or cardiac conditions also face a higher risk, as poor circulation and overall joint health may contribute to the onset of frozen shoulder.

Additionally, autoimmune diseases such as rheumatoid arthritis can cause chronic inflammation in the shoulder capsule, increasing the likelihood of scar tissue formation and stiffness. Individuals who have suffered a rotator cuff injury or undergone shoulder surgery may develop a frozen shoulder due to prolonged immobilization, which prevents normal joint movement and flexibility. Lastly, aging and gender also play a role, with the frozen shoulder being most common in adults between 40 and 60 years old, particularly in women, due to hormonal changes and differences in joint structure.

Studies reveal that 11% of individuals experience frozen shoulder following shoulder surgery, with women being more susceptible (15%) compared to men (8%). This condition can occur regardless of the type of surgical procedure, likely due to postoperative prolonged immobilization, inflammation, or scar tissue formation. Understanding this risk can help patients take proactive measures, such as engaging in early mobility exercises and seeking physical therapy to prevent excessive stiffness and loss of function.

Symptoms and Stages

Frozen shoulder does not develop overnight; instead, it progresses gradually through three distinct stages, each with its own set of symptoms and challenges. The condition worsens over time, starting with increasing pain and stiffness, followed by a prolonged period of restricted movement, and finally, a slow but steady improvement in mobility. Knowing these phases of progression can help patients and healthcare providers choose the most effective treatments at each stage to optimize recovery and restore shoulder function.

• Freezing Stage – In the freezing stage of frozen shoulder, shoulder pain gradually worsens, and stiffness progressively limits movement. Pain often intensifies at night, disrupting sleep and making daily activities challenging. This stage typically lasts between six weeks and nine months, depending on severity and treatment response. Managing symptoms with pain medication, steroid injections, and physical therapy helps slow progression and prevent further immobility.
• Frozen Stage – The frozen stage is marked by decreased pain but significantly increased stiffness, making routine movements like dressing or reaching difficult. This phase lasts around four to six months, during which the shoulder remains highly restricted. Treatment focuses on improving flexibility through range-of-motion exercises, hydrodilatation, and alternative therapies like acupuncture. Regular physical therapy is crucial to maintaining mobility and preventing long-term restrictions.
• Thawing Stage – The thawing stage brings a gradual return of movement as the shoulder capsule loosens and flexibility improves. This phase can take six months to two years, depending on individual recovery rates. Strengthening exercises, progressive range-of-motion work, and sport-specific rehabilitation help restore full function. Patience and consistency with therapy ensure optimal recovery and prevent recurrent stiffness.

When is Surgery Recommended for Frozen Shoulder?

While many cases of frozen shoulder improve with non-surgical treatments, some patients experience persistent pain and severe stiffness that significantly impact their daily lives. When conservative techniques such as physical therapy, corticosteroid injections, and hydrodilatation fail to restore mobility, surgery for frozen shoulder may be the best option. Understanding when to consider surgical intervention can help patients make informed decisions about their treatment and recovery plans.

Indications for Surgical Intervention

Does frozen shoulder require surgery? In most cases, non-surgical treatments effectively manage symptoms and restore mobility. However, surgery may be necessary for patients who experience persistent pain and stiffness lasting beyond six months despite undergoing conservative treatment options. Surgery is also considered when severe loss of shoulder mobility significantly disrupts daily activities, making it difficult to perform simple tasks such as reaching, lifting, or dressing. Additionally, if scar tissue formation severely restricts movement, it can prevent further improvement through non-surgical methods. When physical therapy, corticosteroid injections, and other treatments fail to improve flexibility, a surgical approach may be the best solution to restore function and relieve pain.

Research shows that 47% of medical professionals recommend surgical intervention during the second and third stages of frozen shoulder when the joint capsule has significantly tightened and conservative treatments fail to restore mobility. As the condition progresses, the restricted movement can severely impact daily activities, making arthroscopic capsular release or manipulation under anesthesia viable options for relief. By breaking down adhesions and restoring range of motion, these procedures can improve function and enhance long-term recovery outcomes.

Non-Surgical Treatment Options

Before recommending frozen shoulder surgery, doctors typically explore several non-invasive treatments to improve range of motion and reduce inflammation. One of the most effective methods is physical therapy, which includes range-of-motion exercises, therapeutic ultrasound, and manual therapy to restore shoulder movement gradually. Another common treatment is a corticosteroid injection, specifically an ultrasound-guided glenohumeral corticosteroid injection, which helps reduce inflammation and alleviate pain. For patients who still struggle with limited shoulder mobility, hydrodilatation (arthrographic distension) may be performed. This procedure involves injecting sterile fluid into the joint capsule using image guidance, helping to stretch and loosen the tightened connective tissues. Additionally, pain relievers and anti-inflammatory medications, such as oral anti-inflammatories like ibuprofen, can help manage pain and inflammation, allowing for better movement during rehabilitation. Patients are also advised to adopt activity modification, which involves avoiding painful movements while gradually increasing shoulder flexibility through controlled exercises.

Surgical Procedures for Frozen Shoulder

When non-surgical treatments fail to restore mobility and relieve shoulder stiffness, surgery for frozen shoulder may be the next step. Surgical procedures are designed to release the tightened shoulder capsule, break up adhesions, and restore range of motion. Depending on the severity of the condition, different surgical techniques may be used, including arthroscopic capsular release, manipulation under anesthesia (MUA), and hydrodilatation. In many cases, arthroscopic shoulder surgery is the preferred method, as it is minimally invasive and allows for a quicker recovery compared to open surgery. Each procedure has its benefits and risks, and treatment choice depends on the patient’s needs, medical history, and long-term recovery goals.

Arthroscopic Capsular Release

Arthroscopic capsular release is a minimally invasive surgical technique used to treat severe cases of frozen shoulder. The procedure involves inserting an arthroscope, a small camera-guided instrument, into the shoulder joint to remove scar tissue and release the tightened shoulder capsule. By carefully cutting through the restrictive tissue, this method helps restore mobility and reduce pain. The primary benefits of arthroscopic capsular release include small incisions, a short recovery time, and high effectiveness for patients who have not responded to non-surgical treatments.

Manipulation Under Anesthesia (MUA)

In manipulation under anesthesia (MUA), the patient is placed under regional anesthesia or general anesthesia, allowing the surgeon to forcefully move the shoulder joint through its full range of motion. This procedure is designed to break adhesions and loosen the stiffened joint capsule without the need for incisions. However, MUA comes with certain risks, including rotator cuff tear, fractures in rare cases, and severe postoperative pain due to the sudden stretching of the joint. While it can be effective, MUA is typically recommended in conjunction with physical therapy to maintain the regained range of motion after the procedure.

Hydrodilatation

Also referred to as hydraulic distension or hydroplasty, hydrodilatation is a less invasive alternative to surgery that can significantly improve shoulder flexibility. This procedure, also known as arthrographic hydrodilatation, involves injecting a sterile fluid into the shoulder capsule using image guidance. The injected fluid expands the capsule, stretching and loosening the connective tissues to improve mobility. Hydrodilatation is often used as an intermediate step before surgery and has promising long-term outcomes, particularly in patients who are in the early or mid-stages of frozen shoulder.

Preparing for Frozen Shoulder Surgery

Proper pre-surgical preparation is essential for ensuring a smooth procedure and successful recovery. Before undergoing frozen shoulder surgery, patients must undergo a series of preoperative assessments to determine their suitability for surgery and optimize their overall health. This includes imaging tests such as MRI, X-ray, or ultrasound, discussions with an orthopedic specialist, and the development of a personalized rehabilitation plan. Additionally, following pre-surgery guidelines, such as stopping smoking, managing glucose levels, and engaging in pre-surgery exercises, can help enhance the effectiveness of the procedure and speed up postoperative recovery.

Preoperative Assessments

Before undergoing frozen shoulder surgery, patients must complete a series of preoperative assessments to evaluate the severity of their condition. MRI or ultrasound imaging helps expert radiologists assess the shoulder joint and rule out other conditions. Orthopaedic specialists conduct a thorough examination to determine the best surgical approach. Based on these findings, personalized rehabilitation plans are developed to ensure a smoother recovery. These assessments help optimize surgical outcomes and minimize potential complications.

Pre-Surgery Guidelines

Following specific pre-surgery guidelines can significantly improve healing and recovery after frozen shoulder surgery. Patients are advised to stop smoking, as it can delay tissue repair and increase surgical risks. Managing underlying health conditions like diabetes or thyroid disorders reduces inflammation and improves joint function. Engaging in a pre-surgery exercise program can help strengthen the shoulder muscles and prepare the joint for postoperative rehabilitation. These steps enhance surgical success and promote a faster recovery.

What to Expect During the Surgery

For those considering frozen shoulder surgery, understanding what happens during the procedure can help ease anxiety and set realistic expectations. Most surgical techniques for frozen shoulder, including arthroscopic capsular release and manipulation under anesthesia, are minimally invasive outpatient procedures with a short recovery time. Using regional anesthesia or general anesthesia ensures that patients experience minimal discomfort, and the surgery typically lasts 30 minutes to an hour. Knowing what to expect during the procedure allows patients to mentally and physically prepare, leading to a smoother postoperative experience.

Surgical Procedure Overview

Frozen shoulder surgery is typically performed on an outpatient basis at top medical facilities like the Hospital for Special Surgery. The procedure involves small incisions and lasts between 30 minutes to an hour, making it a minimally invasive option for severe cases. Using arthroscopic surgical techniques, surgeons carefully release the tightened shoulder capsule to restore mobility. Since the incisions are small, the risk of complications is lower, and recovery time is generally shorter compared to open surgery. Patients can usually return home the same day and begin physical therapy soon after to regain full range of motion.

Anesthesia and Pain Management

The surgery is performed under general anesthesia or a regional nerve block, which numbs the shoulder area to ensure patient comfort. Postoperative pain management includes an indwelling nerve catheter, which delivers continuous pain relief in the initial recovery period. Additionally, patients are advised to use icing or apply heat to help manage swelling and discomfort after surgery. Pain medication and oral anti-inflammatories, such as NSAIDs or acetaminophen, are commonly prescribed to reduce inflammation and ease soreness. Patients can focus on rehabilitation and restoring shoulder function more effectively with proper pain control.

Recovery After Frozen Shoulder Surgery

Following frozen shoulder surgery, recovery is crucial for regaining range of motion and ensuring long-term success. While surgery helps release the tight shoulder capsule, physical therapy, and rehabilitation play an essential role in maintaining mobility and preventing stiffness from returning. The first few weeks post-surgery focus on reducing pain and inflammation and gradually restoring movement through guided exercises. Most patients experience significant improvements with personalized rehabilitation plans within 6 weeks to 3 months, though full recovery can take longer. Understanding the expected recovery timeline helps patients stay committed to their treatment plan and achieve the best possible outcomes.

Immediate Postoperative Care

After frozen shoulder surgery, most patients can return home the same day, as the procedure is typically performed outpatient. While some discomfort is expected, sling use is minimal to avoid unnecessary stiffness and promote early movement. Patients are advised to manage pain with icing or applying heat, pain relievers, and anti-inflammatory medication. Mild shoulder swelling is common but usually subsides with proper postoperative care. Early activity modification and gentle movements help prevent complications and support a faster recovery.

Physical Therapy and Rehabilitation

A personalized rehabilitation program is crucial for restoring range of motion and preventing shoulder stiffness after surgery. Therapy includes strengthening exercises, a gradual return to sport, and targeted range-of-motion exercises to rebuild mobility. Additional treatments, such as therapeutic ultrasound and acupuncture management may help reduce pain and inflammation. Patients must follow a structured recovery plan to ensure optimal healing and prevent long-term restrictions. Consistent physical therapy significantly improves long-term outcomes and helps patients regain full function.

Potential Complications

Although frozen shoulder surgery is generally safe, some risks include infection, nerve damage, or excessive shoulder swelling. These complications can often be minimized with proper wound care and adherence to post-surgery guidelines. Persistent stiffness may occur if physical therapy is not followed, leading to limited mobility even after surgery. In rare cases, some patients may experience chronic pain or require additional interventions for full recovery. However, with expert surgical techniques and a well-designed rehabilitation plan, the likelihood of serious complications remains low.

Conclusion

While frozen shoulder surgery is not always necessary, it offers significant relief for those with severe shoulder contracture that does not improve with non-surgical treatments. With advanced surgical techniques, conservative treatments, and proper rehabilitation, patients can regain full range of motion and long-term mobility. Early diagnosis and adherence to a personalized recovery plan are crucial in achieving the best results. By working closely with an orthopedic specialist and physical therapist, patients can optimize their healing and prevent ra ecurrence. Whether through non-invasive methods or surgery, the goal is to restore pain-free movement and improve quality of life.
