Key Takeaways
- Rotator cuff tears and frozen shoulder are common causes of shoulder pain, but they affect different structures within the joint.
- Rotator cuff tears often cause pain with movement and weakness, while frozen shoulder leads to stiffness and severely limited motion.
- Risk factors, causes, and progression differ between the two conditions, making proper diagnosis essential.
- Imaging studies and physical exams help distinguish between rotator cuff injuries and frozen shoulder.
- Dr. Kevin McCarthy provides expert diagnosis and personalized shoulder care, including nonsurgical treatment and minimally invasive shoulder arthroscopy, in Hollywood, FL. Schedule an appointment today for an accurate evaluation and targeted treatment plan.
Understanding Shoulder Pain and Why the Cause Matters
The shoulder is one of the most complex joints in the body, allowing for a wide range of motion. Because of this complexity, several conditions can cause similar symptoms. Two frequently confused diagnoses are rotator cuff tears and frozen shoulder.
Although both conditions can limit daily activities and cause ongoing discomfort, treating the wrong condition may delay recovery. Identifying whether shoulder pain is caused by tendon damage or joint stiffness is the first step toward effective relief.
Rotator Cuff Tears: Symptoms and Characteristics
The rotator cuff consists of four muscles and tendons that stabilize the shoulder and enable arm lifting and rotation. A tear occurs when one or more of these tendons becomes damaged.
Common Symptoms of a Rotator Cuff Tear
- Shoulder pain when lifting or lowering the arm
- Discomfort during overhead activities
- Pain when lying on the affected shoulder
- Weakness when lifting or rotating the arm
- Clicking or popping sensations with movement
- Reduced shoulder strength and endurance
Pain from a rotator cuff tear often worsens with activity and may interfere with work, exercise, or household tasks.
Frozen Shoulder: Symptoms and Characteristics
Frozen shoulder, also known as adhesive capsulitis, occurs when the connective tissue surrounding the shoulder joint thickens and tightens. This restricts motion and leads to progressive stiffness.
Common Frozen Shoulder Symptoms
- Gradual onset of shoulder pain
- Increasing stiffness over time
- Severe limitation in the shoulder range of motion
- Difficulty performing everyday tasks
- Pain that may improve slightly as stiffness worsens
Frozen shoulder typically progresses through stages: pain, prolonged stiffness, and gradual improvement.
Rotator Cuff Tear vs. Frozen Shoulder: Key Differences
| Feature | Rotator Cuff Tear | Frozen Shoulder |
|---|---|---|
| Primary Issue | Torn shoulder tendon | Tightened joint capsule |
| Pain Pattern | Worse with movement | Constant, aching pain |
| Strength | Noticeable weakness | Strength is limited by stiffness |
| Range of Motion | Pain-limited | Severely restricted |
| Onset | Sudden or gradual | Gradual progression |
This comparison highlights why an accurate diagnosis is critical when evaluating shoulder pain.
Causes and Risk Factors for Each Condition
Causes of Rotator Cuff Tears
- Repetitive overhead motion
- Age-related tendon degeneration
- Acute injuries such as falls
- Heavy lifting or sudden arm movements
- Poor shoulder mechanics
Causes of Frozen Shoulder
- Prolonged shoulder immobilization
- Inflammatory conditions
- Diabetes or metabolic disorders
- Prior shoulder injury or surgery
- Unknown (idiopathic) causes
Risk factors help guide evaluation, but are not sufficient alone to determine a diagnosis.
Diagnosing Shoulder Pain Accurately
Distinguishing between a rotator cuff tear and frozen shoulder requires a thorough orthopedic evaluation.
Diagnostic Methods Used
- Physical examination to assess strength and motion
- Range-of-motion testing to identify stiffness versus weakness
- X-rays to rule out bone abnormalities
- MRI or ultrasound to evaluate soft tissue damage
Imaging studies help confirm tendon injuries and assess joint structures
Treatment Options for Rotator Cuff Tears
Treatment depends on the severity of the tear, the duration of symptoms, and the patient's activity level.
Nonsurgical Rotator Cuff Treatment
- Physical therapy to strengthen shoulder stabilizers
- Anti-inflammatory medications for pain relief
- Activity modification to reduce strain
- Targeted injections to reduce inflammation
Many partial tears improve with conservative care when diagnosed early.
Shoulder Arthroscopy
For persistent or severe tears, shoulder arthroscopy may be recommended. This minimally invasive procedure repairs damaged tendons through small incisions, offering:
- Reduced postoperative discomfort
- Faster recovery
- Improved shoulder strength and function
Treatment Options for Frozen Shoulder
Frozen shoulder treatment focuses on restoring mobility and reducing pain.
Conservative Frozen Shoulder Care
- Physical therapy emphasizing gentle stretching
- Anti-inflammatory medications
- Injections to reduce inflammation and discomfort
- Gradual return to shoulder movement
Most patients improve with guided care, though recovery may take several months.
When to Seek Medical Attention for Shoulder Pain
You should seek evaluation if:
- Shoulder pain lasts longer than a few weeks
- Motion becomes increasingly limited
- Pain disrupts sleep or daily activities
- Symptoms follow an injury or trauma
Early diagnosis improves treatment success and reduces long-term limitations.
Find Clarity, Relief, and a Path Back to Shoulder Mobility

Frequently Asked Questions
What is the main difference between a rotator cuff tear and frozen shoulder?
A rotator cuff tear causes tendon damage and weakness, while frozen shoulder causes stiffness due to tightening of the joint capsule.
Can frozen shoulder heal without treatment?
Frozen shoulder may improve over time, but treatment helps reduce pain and restore motion more efficiently.
Do rotator cuff tears always require surgery?
No. Many rotator cuff tears respond well to physical therapy, medications, and injections.
How is shoulder pain diagnosed?
Diagnosis involves a physical exam and imaging such as X-rays, MRI, or ultrasound to evaluate joint and tendon health.
When should I see a shoulder specialist?
If pain persists, limits movement, or interferes with daily activities, evaluation by an orthopedic specialist is recommended.
