โฌ Rotator cuff tears (RCTs) are a leading cause of shoulder pain and disability in older adults, affecting up to 50% of people in their 80s.
โฌ While surgical repairs are common, elderly patients face a massive challenge: exceptionally high post-surgery retear rates.
โฌ A recent comprehensive review highlights that aging sabotages shoulder health and surgical recovery by driving severe degenerative changes across four critical areas of the shoulder.

โฌ Aging exacerbates muscle atrophy (shrinking) and fatty infiltration (fat replacing muscle tissue).
โฌ Additionally, aging induces cellular senescence in muscle stem cells, crippling the muscle's natural ability to regenerate and heal after an injury or surgery.

โฌ As we age, tendons lose vital lubricating and elastic components, making them stiffer and weaker.
โฌ Senescence in tendon-derived stem cells further impairs tendon healing, making aging tissue vulnerable to "cheese-wiring" where surgical sutures slice right through the weakened tendon.

โฌ The enthesisโthe critical transition zone where the tendon attaches to the boneโloses its regenerative capacity with age.
โฌ Stem cells in this area lose their ability to form new tendon or cartilage, creating a vicious cycle that prevents proper healing after surgery.

โฌ Aging frequently brings osteopenia and osteoporosis, significantly impairing bone quality.
โฌ For orthopedic surgeons, this means surgical anchors placed in the bone are highly prone to pulling out, which drastically increases the risk of the repair failing.

โฌ Addressing aging-related RCTs requires moving beyond standard surgery.
โฌ The authors emphasize the need for a multidisciplinary approach combining orthopedics, geriatrics, and endocrinology.
โฌ Emerging therapeutic strategies hold significant promise, including the use of mesenchymal stem cell (MSC) exosomes to prevent fatty infiltration in muscles, pharmacological inhibitors to stop tendon degradation, and anti-osteoporosis treatments (like teriparatide or bisphosphonates) to improve bone density and secure surgical anchors.
