Do I Need Antibiotics During or After Shoulder Surgery?

Antibiotics are commonly used during shoulder surgery to reduce the risk of infection. Shoulder surgery has unique considerations because bacteria that normally live on the skin around the shoulder can contribute to postoperative infection.

Modern infection prevention strategies involve:

• Preoperative skin preparation
• Intravenous antibiotics before incision
• Sterile surgical technique
• Careful wound management
• Patient-specific risk assessment

Why antibiotics are important in shoulder surgery

One of the most important goals during shoulder surgery is prevention of infection. Although infection after shoulder surgery is uncommon, it can be serious when it occurs.

The shoulder is unique because a bacteria called Cutibacterium acnes commonly lives around the shoulder and hair follicles. This organism may contribute to delayed or low-grade infections after shoulder surgery, especially shoulder replacement surgery.

Because of this, infection prevention in shoulder surgery often differs somewhat from hip and knee surgery.

When antibiotics are typically given

Most patients receive intravenous antibiotics shortly before surgery begins. This allows antibiotics to reach appropriate tissue levels during the procedure itself.

Additional antibiotics during surgery may occasionally be needed for:

• Long procedures
• Revision surgery
• Significant blood loss
• Complex reconstruction

In many routine shoulder surgeries, antibiotics are stopped shortly after surgery and prolonged antibiotic use is not necessary.

Do patients need antibiotics after surgery?

Most patients do not require long-term antibiotics after routine shoulder surgery.

Extended antibiotics may occasionally be considered in:

• Revision surgery
• Known prior infection
• High-risk reconstruction
• Unexpected intraoperative findings

The goal is to use antibiotics appropriately while avoiding unnecessary prolonged antibiotic exposure.

What this means for patients

Antibiotics are an important part of infection prevention during shoulder surgery, but they are only one component of a broader strategy that includes surgical technique, skin preparation, sterile protocol, and postoperative care.

The goal is to minimize infection risk while supporting safe recovery and long-term shoulder function.
