Surgery is a common treatment for a rotator cuff tear, but it is the rare exception that a rotator cuff tear requires surgery. The truth is, that the vast majority, more than 99%, of rotator cuff tears are never treated with surgery. Most patients with shoulder pain resulting from a rotator cuff tear can be treated without surgery.
Rotator Cuff Tears
The rotator cuff is the group of muscles and tendons that surround the ball-and-socket shoulder joint. Four muscles make up the rotator cuff. Rotator cuff problems range from inflammation and tendonitis, to partial tears, to full tears of the tendon.
Most people who have symptoms from a rotator cuff problem develop pain around the shoulder. Other common symptoms include weakness of the muscles and limited mobility of the joint. Rotator cuff problems can be diagnosed by examining a patient. Sometimes tests including x-rays, MRIs, and ultrasound, may be used to determine the extent of damage to the rotator cuff.
Tears Are Common, So Common They're Normal
The truth is that most people will eventually tear their rotator cuff. As people age, rotator cuff tears become increasingly common, even in people who never have symptoms of shoulder pain. Just as hairs turn grey and skin wrinkles, as people get older, rotator cuffs tear.
Numerous studies have tried to identify how many people have rotator cuff tears. The results vary, but in groups of adults who have no shoulder pain symptoms, the number of people with rotator cuff tears identified by either MRI or ultrasound is between 5 and 40%. No matter what number you choose, that's a lot of people walking around with rotator cuff tears. Furthermore, these numbers don't even include people with partial rotator cuff tears, a finding that is undoubtedly much more common. The most commonly cited number is 20% of the population has evidence of a full-thickness rotator cuff tear.
We know that rotator cuff tears tend to be more common as people age (about 10% of 40 year olds, but more than 50% of 80 year olds). Rotator cuff tears are also more common in the dominant arm and in people who have sustained some type of trauma to the shoulder.
Rotator Cuff Tear TreatmentTreatment of a torn rotator cuff varies depending on the type of injury and the type of patient. Since a rotator cuff tear often exists in people with no symptoms of a tear, treatment does not necessarily need to include repairing the torn tendon. Most often, simple treatments are tried first, and consideration of a surgical repair is only made if these simple treatments fail to provide relief.
There are some exceptions, and some people with rotator cuff tears may be better off with immediate surgery. These tend to include younger patients who have had a recent acute injury to their shoulder.
When Surgery Is Necessary
It is important for people to understand that rotator cuff surgery may be an appropriate option for shoulder pain resulting from a rotator cuff tear. However, it is also important to understand that rotator cuff tears are incredibly common. So common that, as people age, they become expected. Therefore, having a rotator cuff tear is not a reason in and of itself to have surgery. The decision about when surgery is appropriate is complicated, and depends on a number of factors that you need to discuss with your doctor.
On the other hand, patients should be reassured, that while some rotator cuff tears do cause pain, the vast majority will never require surgery, and many people can find relief with nonsurgical treatments. Patients who are told they need rotator cuff surgery should understand the reason for surgery. In most cases, non-surgical treatments should be attempted first, the exception being in younger patients who have rotator cuff tears resulting from traumatic injuries. If you are unsure of the necessity of a rotator cuff surgery, a second opinion can be helpful.
