What Is the Most Common Shoulder Surgery?

The shoulder joint allows for an extensive range of motion, but this mobility compromises stability, making it susceptible to injury and deterioration. Since the joint is relied upon for daily activities, problems often cause pain and functional limitations requiring medical intervention. Many conditions are progressive, worsening over time, making surgical treatment necessary for restoring comfort and capability.

Identifying the Most Frequent Procedure

The procedure performed most often on the shoulder is the Rotator Cuff Repair, sometimes combined with a subacromial decompression. This surgery addresses widespread tendon damage resulting from repetitive strain and aging. Millions of people experience rotator cuff problems severe enough to warrant surgical correction, making this the most common shoulder operation.

Understanding the Condition Requiring Surgery

The rotator cuff consists of four muscles—the supraspinatus, infraspinatus, teres minor, and subscapularis—and their tendons, which surround the head of the humerus. This group stabilizes the shoulder while allowing the arm to rotate and lift. A tear compromises this balance, causing weakness and pain that affects movement. Most tears are degenerative, resulting from chronic wear and tear that slowly frays and weakens the tendon tissue over decades.

Chronic degeneration is often accelerated by impingement syndrome, which frequently precedes a full tear. Impingement occurs when the tendons are squeezed between the humerus and the acromion, a bony part of the shoulder blade, especially when lifting the arm overhead. This repeated friction thins the tendon, making it vulnerable to a complete tear from minor stress. Less commonly, tears are acute, resulting from a sudden injury like a fall or a forceful lift.

Tears are categorized as partial-thickness (damaged but not severed) or full-thickness (fully separated from the bone). Surgery is recommended for full-thickness tears and for partial tears that do not respond to several months of non-operative treatments, such as physical therapy and medication. The supraspinatus tendon is involved in the majority of these injuries due to its position and role in overhead movement.

The Surgical Process and Techniques

The standard approach for Rotator Cuff Repair is arthroscopic surgery, a minimally invasive technique that avoids large incisions and extensive muscle disruption. The surgeon makes several small puncture wounds, through which specialized instruments and an arthroscope (a tiny camera) are inserted. The arthroscope projects images onto a monitor, allowing a clear view of the joint’s interior. This visualization permits the surgeon to assess the tear and associated damage, such as bone spurs or inflamed tissue, which are often removed during debridement.

The next step involves mobilizing the torn tendon and pulling it back to its correct anatomical position on the humerus. To secure the tendon, the surgeon uses small suture anchors placed into the bone. Attached high-strength sutures are woven through the torn tendon and tied, firmly reattaching it to its original bony insertion site. This reattachment creates the necessary environment for biological healing, allowing the tendon tissue to gradually grow back into the bone.

While arthroscopy is preferred for precision and reduced discomfort, open surgery may be necessary for complex or massive tears. Regardless of the technique, the goal is to restore the integrity of the tendon-to-bone connection and allow the shoulder to regain normal function. The repair must be protected post-operation to allow healing time.

Life After Surgery

Recovery from Rotator Cuff Repair is a gradual, multi-stage process requiring strict adherence to a rehabilitation program. Immediately following the procedure, the arm is typically immobilized in a sling for four to six weeks to protect the surgical repair from stress. Pain management, often involving medication, is a primary focus during this initial phase.

Physical therapy begins almost immediately, sometimes within the first week. Initially, the therapist focuses on passive range-of-motion exercises, moving the patient’s arm without engaging the repaired muscles. This controlled movement prevents stiffness and scar tissue formation while protecting the surgical site. Active motion, where the patient moves the arm independently, usually starts after the sling is removed, around six to eight weeks post-surgery.

The strengthening phase of rehabilitation begins later, generally after three to four months, once the tendon has achieved sufficient initial healing. This stage restores the muscle power needed for daily and overhead activities. While patients feel functional improvement within a few months, full recovery, including the return to sports or heavy manual labor, typically takes six months to a year.
