Shoulder pain is a common complaint as we age, but a recent study suggests that signs of rotator cuff damage are even *more* common – and often present even without any pain at all. Researchers in Finland found that nearly all participants over the age of 40 showed evidence of fraying, tears, or other abnormalities in their rotator cuffs when examined with MRI scans. This finding, published in JAMA Internal Medicine on February 16, 2026, challenges the traditional link between rotator cuff issues and reported pain, raising questions about how we understand and manage shoulder health as we get older.
The study, led by Thomas Ibounig, MD, of the Finnish Centre for Evidence-Based Orthopaedics at the University of Helsinki, involved analyzing MRI scans of 603 Finnish adults. The research revealed a surprisingly high prevalence of rotator cuff abnormalities. While the exact percentage varied depending on the specific type of damage, the overall finding was consistent: the older the participant, the more likely they were to have some degree of rotator cuff issue. This prevalence of shoulder abnormalities in an aging population highlights the necessitate to re-evaluate what constitutes a “normal” shoulder for individuals over 40.
What is the Rotator Cuff and Why Does This Matter?
The rotator cuff is a group of muscles and tendons that surround the shoulder joint. These tissues work together to stabilize the shoulder, allowing for a wide range of motion. Damage to the rotator cuff can occur due to injury, overuse, or simply the wear and tear of aging. Traditionally, doctors have linked rotator cuff tears and other abnormalities to shoulder pain and limited mobility. However, this new research suggests that this isn’t always the case.
“We found that a significant number of people had abnormalities on their MRI scans, but reported no pain or functional limitations,” explains Dr. Ibounig in a related statement. “This suggests that many of these abnormalities may be a normal part of the aging process and don’t necessarily require treatment.” What we have is a crucial distinction, as it could potentially reduce unnecessary surgeries and other interventions for individuals who aren’t experiencing symptoms. The implications of this research extend to how doctors approach shoulder pain complaints, potentially shifting the focus from structural abnormalities seen on imaging to a more holistic assessment of a patient’s symptoms and functional abilities.
The Prevalence of Asymptomatic Rotator Cuff Tears
The Finnish study isn’t the first to suggest a disconnect between rotator cuff abnormalities and pain. Previous research has shown that a substantial percentage of people over the age of 60 have rotator cuff tears that don’t cause any symptoms. However, the scale of the findings in this new study – nearly universal abnormalities in those over 40 – is particularly striking. The researchers emphasize that this doesn’t mean rotator cuff tears are harmless. In some cases, they can lead to significant pain and disability. But it does suggest that many people can live with these abnormalities without experiencing any problems.
Who is Affected by Rotator Cuff Issues?
While the Finnish study focused on adults over 40, rotator cuff problems can affect people of all ages. Athletes who participate in overhead sports, such as baseball, tennis, and swimming, are at increased risk of rotator cuff injuries. However, the study highlights that age is a significant risk factor, with the prevalence of abnormalities increasing steadily with each decade. Individuals with jobs that require repetitive overhead movements, such as painters or construction workers, may also be more prone to rotator cuff issues. Understanding these risk factors can help individuals take preventative measures to protect their shoulder health.
What Does This Mean for Your Shoulders?
If you’re over 40, it’s likely that your rotator cuff isn’t in perfect condition, even if you don’t have any pain. This doesn’t necessarily mean you need to worry. The researchers recommend that people with no symptoms shouldn’t undergo routine MRI scans to check for rotator cuff abnormalities. However, if you *do* experience shoulder pain, it’s important to see a doctor to get a proper diagnosis and discuss treatment options. Treatment may include physical therapy, pain medication, or, in some cases, surgery. The key takeaway is that imaging findings alone shouldn’t dictate treatment decisions; the focus should always be on the patient’s symptoms and functional limitations.
The study team is continuing to investigate the factors that contribute to the development of rotator cuff abnormalities and the reasons why some people experience pain while others don’t. Further research is needed to determine the optimal management strategies for individuals with asymptomatic rotator cuff tears. The researchers plan to follow the study participants over time to see how their rotator cuff abnormalities progress and whether they eventually develop symptoms. The next phase of the research will involve a more detailed analysis of the genetic and lifestyle factors that may influence rotator cuff health.
