Shoulder pain is one of the most common orthopedic complaints among adults, especially those over 40 or individuals who perform repetitive overhead movements. Two of the most frequent causes are rotator cuff injuries and frozen shoulder, conditions that can feel similar at first but have entirely different causes, symptoms, and treatments.
At Dr. Rytel Sports Medicine, we specialize in diagnosing and treating shoulder conditions such as rotator cuff tears and frozen shoulders using advanced orthopedic techniques and compassionate care. Serving Pittsburgh and Brackenridge, PA, Dr. Michael Rytel, a board-certified orthopedic surgeon and sports medicine specialist, helps patients regain shoulder strength, flexibility, and confidence through personalized treatment plans. If you’re struggling with ongoing shoulder stiffness or weakness, now is the time to get a professional diagnosis.
Let’s explore how to tell the difference between these two common shoulder conditions and the best steps for recovery.
What Is the Difference Between Frozen Shoulder and Rotator Cuff Tear?
Though both cause shoulder pain and limit motion, the difference between frozen shoulder and rotator cuff tear lies in the underlying structure affected.
- Frozen shoulder (adhesive capsulitis) develops when the shoulder joint capsule thickens and tightens, restricting movement.
- A rotator cuff tear, on the other hand, involves damage to one or more of the four tendons that stabilize the shoulder and help lift and rotate the arm.
Frozen shoulder is primarily a stiffness problem, while a rotator cuff tear is a strength problem. Understanding this distinction is essential because each condition requires a very different treatment approach.
Frozen Shoulder Symptoms: Gradual Stiffness and Limited Motion
Frozen shoulder typically develops in stages and often without a clear injury. It’s more common in people recovering from surgery, those with diabetes, or individuals who have kept their arm immobile for long periods.
Key Frozen Shoulder Symptoms
- Progressive stiffness that worsens over time.
- Dull, constant pain deep in the shoulder.
- Limited movement, even when someone else tries to move your arm for you (restricted passive range of motion).
- Nighttime pain that interferes with sleep.
The Three Stages of Frozen Shoulder
- Freezing Stage: Pain increases, and the range of motion starts to decrease.
- Frozen Stage: Pain may lessen, but stiffness severely limits daily activities.
- Thawing Stage: Gradual improvement in mobility over several months.
Because frozen shoulder can take up to 12–18 months to fully resolve, early evaluation and treatment can make a significant difference in recovery time and comfort.
Rotator Cuff Symptoms: Pain With Movement and Weakness
A shoulder pain rotator cuff tear is often the result of repetitive motion, trauma, or natural wear and tear as we age. It can range from mild inflammation (tendinitis) to a complete tendon rupture.
Key Rotator Cuff Symptoms
- Sharp or aching pain when lifting or rotating your arm.
- Weakness when trying to raise your arm overhead.
- Clicking or popping sounds when moving the shoulder.
- Pain that radiates down the arm, especially during activity.
- Difficulty sleeping on the affected side.
Unlike frozen shoulder, a rotator cuff tear limits active movement; you can’t lift your arm because the muscle lacks strength. However, a doctor may still be able to move your arm for you, showing that the joint itself isn’t “frozen.”
How Each Condition Affects Shoulder Mobility and Pain
The most reliable way to distinguish a frozen shoulder from a rotator cuff tear is by observing how your shoulder moves and how the pain behaves.
With frozen shoulder, the pain is a constant, dull ache that worsens with movement. Both active and passive motion are restricted, meaning even when someone else tries to move your arm, it feels stiff and limited. The condition usually develops slowly, often without injury, and recovery can take several months to a year.
In contrast, a rotator cuff tear causes sharp pain during specific movements, especially when lifting or rotating your arm. Mobility is reduced only during active motion; you may not be able to raise your arm, but someone else can move it for you. The onset is often sudden, linked to overuse or trauma, and recovery time depends on the tear’s severity, typically lasting weeks to months.
Recognizing these differences ensures faster, more accurate diagnosis and prevents delays in effective treatment.
Why Accurate Diagnosis Is Crucial for Effective Treatment
Because both conditions cause shoulder pain and stiffness, an accurate diagnosis is essential for proper healing. Misdiagnosing a rotator cuff tear as frozen shoulder (or vice versa) can delay recovery and increase the risk of long-term damage.
At Dr. Rytel Sports Medicine, diagnosis typically includes:
- Comprehensive physical examination to assess range of motion, strength, and tenderness.
- Imaging tests, such as MRI or ultrasound, are used to detect tendon tears or joint capsule inflammation.
- Specialized orthopedic assessments, like the rotator cuff tear test, are used to pinpoint the exact source of pain.
Once the cause is identified, Dr. Rytel creates a customized treatment plan designed to relieve pain, restore function, and help you return to your favorite activities safely.
Treatment Options for Frozen Shoulder and Rotator Cuff Injuries
While both conditions can improve with proper care, their treatments differ significantly.
Frozen Shoulder Treatment
- Physical therapy: Focuses on gentle stretching to restore motion.
- Anti-inflammatory medications: Reduce pain and stiffness.
- Orthobiologic injections: PRP (Platelet-Rich Plasma) therapy can help stimulate healing.
- Minimally invasive procedures: In severe cases, arthroscopic release may be recommended to loosen the joint capsule.
Rotator Cuff Treatment
- Rest and activity modification: Avoid overhead movements to prevent further damage.
- Physical therapy: Strengthens shoulder stabilizing muscles and improves mobility.
- Orthobiologic injections: PRP or BMAC (Bone Marrow Aspirate Concentrate) treatments promote natural tendon repair.
- Arthroscopic rotator cuff repair: When tears are severe, surgery may be needed to reattach the tendon and restore strength.
At Rytel Sports Medicine, Dr. Rytel tailors every treatment plan to the individual, whether you’re an athlete, weekend warrior, or someone recovering from daily strain.
When to Consult a Pittsburgh Shoulder Specialist

Frequently Asked Questions
How can I tell if I have a frozen shoulder or a rotator cuff tear?
Frozen shoulder causes stiffness in all directions, while a rotator cuff tear causes pain and weakness during active movement.
Can both conditions occur together?
Yes. Sometimes a rotator cuff injury leads to immobility, which can cause frozen shoulder.
How long does recovery take?
Frozen shoulder recovery can take 6–12 months, while rotator cuff healing depends on severity, ranging from weeks to several months.
Do all rotator cuff tears require surgery?
No. Many partial tears respond well to therapy and orthobiologic injections.
Can physical therapy help both conditions?
Yes. Physical therapy plays a vital role in restoring strength and flexibility for both frozen shoulder and rotator cuff injuries.
