The rotator cuff is a group of four muscles and tendons that stabilize the shoulder and allow you to lift and rotate your arm. It’s also one of the most commonly injured structures in the body, especially as we age or put repetitive stress on the shoulder through sports or manual work. Here’s what’s actually going on when a rotator cuff tear happens, and how it’s typically treated.
How tears happen
Rotator cuff tears fall into two general categories. Acute tears result from a specific incident — falling on an outstretched arm, lifting something too heavy, or a sudden jerking motion. Degenerative tears develop gradually from repetitive overhead motion (common in painters, carpenters, and overhead athletes) or simply from age-related wear on the tendon, which loses blood supply and elasticity over time. Many people over 60 have some degree of rotator cuff tear without even realizing it, since not all tears cause pain.
Recognizing the symptoms
The hallmark signs include a dull ache deep in the shoulder that worsens with overhead reaching, weakness when lifting or rotating the arm, and pain that disrupts sleep, particularly when lying on the affected side. A “catching” or crackling sensation during certain movements is also common. With acute, traumatic tears, the onset is sudden and often severe; degenerative tears tend to announce themselves more gradually as a nagging ache that slowly limits what you can do.
How it’s diagnosed
A physical exam that tests shoulder strength and range of motion through specific movements often points strongly toward a rotator cuff problem. MRI is the gold standard for confirming a tear, showing its size and location and helping the surgeon decide whether it’s a candidate for surgical repair or better managed non-surgically.
Treatment options: surgery isn’t always first
Not every tear needs an operation. Partial tears and many degenerative tears in less active patients often respond well to physical therapy focused on strengthening the surrounding muscles, along with anti-inflammatory medication and sometimes a corticosteroid injection. Surgery becomes the stronger recommendation for full-thickness tears, tears in younger or more active patients, or cases where months of conservative treatment haven’t improved function. Arthroscopic rotator cuff repair, done through small incisions with a camera, is the most common surgical approach and generally has a strong track record for restoring strength and reducing pain.
What recovery looks like
Recovery from surgical repair is a longer process than many patients expect — typically four to six months to return to full activity, with the shoulder often immobilized in a sling for the first several weeks to protect the healing tendon. Physical therapy is introduced gradually, starting with passive range-of-motion exercises before progressing to active strengthening. Patience during the early weeks matters: pushing too hard too soon is one of the more common causes of re-tear.
