Hearing you've torn a tendon in your shoulder can be worrying, especially if it's mentioned on an MRI report. However, a partial tear doesn't mean the tendon has completely ruptured, and many people return to work, the gym and sport without needing an operation.
At The Addison Physiotherapy, we regularly assess and treat partial rotator cuff tears. Our goal is to reduce pain, restore strength and help you confidently return to the activities you enjoy while reducing the risk of ongoing shoulder problems.
Key Takeaways
- A partial tear means only part of the tendon has been injured.
- Most partial tears improve without surgery.
- MRI findings don't always match the amount of pain you're experiencing.
- Progressive strengthening is the foundation of rehabilitation.
- Early physiotherapy can improve recovery and restore shoulder function.
What causes rotator cuff tear?
The rotator cuff is made up of four muscles and their tendons, which help stabilise and move the shoulder.
A partial tear occurs when some of the tendon fibres are damaged, but the tendon remains attached to the bone. This differs from a full-thickness tear, where the tendon is completely torn through.
Partial tears most commonly affect the supraspinatus tendon, particularly where it attaches to the top of the arm bone.
What causes a partial rotator cuff tear?
Partial tears may develop gradually over time or occur following a specific injury.
Common causes include:
- Repetitive overhead activity
- Heavy lifting
- Gym training
- Falls onto the shoulder
- Age-related tendon changes
- Long-standing rotator cuff tendinopathy
In many people, the tendon has gradually weakened before the tear develops.
What are the symptoms of shoulder impingement?
People commonly experience:
- Pain lifting the arm overhead
- Pain reaching behind your back
- Weakness during pressing or lifting
- Pain sleeping on the affected shoulder
- Pain during throwing or swimming
- Shoulder pain that lingers after activity
Some people have surprisingly little pain despite a tear, while others experience significant discomfort with relatively small tears.
When should I see a physiotherapist?
It's worth booking an assessment if:
- Shoulder pain persists for more than one to two weeks.
- You're noticing increasing weakness.
- Pain is affecting sleep.
- You struggle with work, sport or gym activities.
- Symptoms began after a fall or lifting injury.
Early assessment helps determine whether your symptoms are likely to respond well to rehabilitation or whether further investigation is appropriate.
Do I need imaging?
Not always.
Many partial tears are first suspected during a physiotherapy assessment.
An MRI or ultrasound may be useful if:
- There was a significant traumatic injury.
- There is considerable weakness.
- Symptoms aren't improving after rehabilitation.
- Surgery is being considered.
It's important to remember that many people have partial rotator cuff tears on MRI without experiencing any shoulder pain. Imaging findings should always be interpreted alongside your symptoms and clinical examination.
Imaging may be recommended if:
- You experienced a significant traumatic injury.
- There is substantial weakness.
- Symptoms aren't improving despite rehabilitation.
- A larger rotator cuff tear is suspected.
MRI findings don't always match symptoms, so scans should always be interpreted alongside a thorough clinical assessment.
How is partial rotator cuff tear treated?
Most partial tears can be managed successfully without surgery.
Treatment usually includes:
Education
Understanding your diagnosis and what activities are safe during recovery.
Load Management
Temporarily reducing activities that significantly aggravate your shoulder while maintaining comfortable movement.
Progressive Strengthening
Improving the strength of the rotator cuff and surrounding muscles helps reduce pain, restore function and improve the tendon's ability to tolerate load.
Return to Activity
Gradually progressing back to work, gym, sport or overhead activities with a structured rehabilitation program.
The goal isn't simply to reduce pain—it's to rebuild a stronger, more resilient shoulder.
Can I keep exercising?
Usually, yes.
Most people don't need complete rest. Instead, exercises are modified to avoid excessive pain while maintaining shoulder strength.
For example, overhead pressing may be temporarily reduced, while rowing, lower body training and other pain-free exercises can usually continue.
Your physiotherapist will guide you on which movements are appropriate throughout each stage of recovery.
How long does recovery take?
Recovery varies depending on the size of the tear, your symptoms and how consistently rehabilitation is completed.
