Most people report improved shoulder strength and reduced pain after rotator cuff surgery,1 but a small portion of rotator cuff surgery patients experience complications.
Possible surgical complications include:
- In general, surgery involving anesthesia, which includes rotator cuff surgery, poses a slight risk of stroke, heart attack, pneumonia, or blood clot.
- Damage to adjacent nerves and blood vessels. One study found that 1 to 2% of patients going through rotator cuff surgery experience nerve damage.2
- Infection in the shoulder. Only 0.16 to 1.9% of patients cited deep infection after arthroscopic or mini-open surgery.4
- Stiffness is common after rotator cuff surgery. A retrospective study of 103 postoperative patients found that 20% experienced stiffness following open rotator cuff operation; stiffness ended in 6 to 12 months after surgery with positive outcomes.4
Occasionally, patients tear their repairs. The chance of this occurring increases with the size of the original tear.
Factors That Impact Rotator Cuff Surgery Rehabilitation:
There are certain factors that influence the recovery from rotator cuff surgery. These include:
- Surgical approach. There are several surgical methods used to treat a rotator cuff injury: open surgery, arthroscopic, or a combination of the two. While each option can effectively treat the patient, an arthroscopic procedure involves considerably less pain after the surgery.5
- Tendon tear size. It is generally agreed that smaller tears have better outcomes than larger ones—those greater than 5 cm.5
- Tissue quality. Tissue quality varies between patients, and can be evaluated on preoperative magnetic resonance imaging (MRI) scan prior to surgery. Knowing the tissue quality influences patient rehabilitation.
- Location and type of tear. Tears affecting the backside portion of the shoulder demand more care and limited shoulder rotation motion.
- Rehabilitation method. Rehabilitation is critical to a patient’s success following rotator cuff surgery. Patients using a proficient physical therapist show substantially more improvement than those helped by home therapy programs, one paper clinically observed.5
- Patient factors. Age, activity level, lifestyle choices, occupation, and hobbies may reflect rehabilitation from rotator cuff surgery.
- Several authors have found that older patients, those older than 65 years old, have less successful postoperative outcomes.
- Healing time is affected by health conditions like diabetes mellitus or whether or not the patient smokes.
- According to one study, patients with worker’s compensation double the time to return to work compared to other rotator cuff patients.5
- A patient’s activity level prior to surgery is often indicative of activity level following surgery.
Above all, both the patient and physician have a role in the recovery of the rotator cuff.

What If Rotator Cuff Surgery Does Not Work?
While rotator cuff surgeries can have positive, lasting results, not all surgical repairs heal.6 When rotator cuff repair is unsuccessful, a patient experiences postoperative pain and/or shoulder stiffness. These patients may choose to have a second surgery.
- A second repair may be done if sufficient quality and quantity of tissue remain.
- A surgical release of scar tissue can improve the patient’s range of motion.
Second repair surgeries—sometimes called “revision surgeries—can be technically challenging and generally have lower success rates than original repair surgeries.7
Many second repair surgeries reduce pain, but they are less likely to improve shoulder function. Improved functional outcomes are mostly seen in patients who:7
- Have healthy, intact deltoid muscles at the top of the shoulder.
- Were able to raise the arm preoperatively “above the horizontal,” or when the arm is at 90 degrees or greater as found in swimming and throwing sports, for example.8
- Have rotator cuff tissue of decent quality (more likely in patients who have experienced a shoulder injury than degenerative tears).
- Had only one surgical procedure before the repair.
Second repairs to large tears are generally less likely to be successful.9
