A partial-thickness rotator cuff tear means part of a shoulder tendon is torn but the tendon is not fully detached. The scan finding needs to be interpreted alongside pain, strength, movement and function.
Partial-thickness rotator cuff tears are common findings on shoulder ultrasound or MRI. They may follow injury, repetitive loading or age-related tendon change. Some are painful and functionally limiting, while others are incidental findings.
The key question is not only whether a tear is present, but whether it matches the patient’s symptoms and functional limitation. Assessment looks at pain behaviour, shoulder range, strength, irritability, work demands and training goals.
Non-surgical management is often appropriate. This commonly includes education, temporary modification of aggravating loads and progressive strengthening of the rotator cuff, deltoid and shoulder blade muscles. Procedures such as injection, PRP or shockwave may be discussed when symptoms persist despite a clear rehabilitation plan, but they should not replace the strength and load-management work that helps restore shoulder capacity.
