What is Shoulder Arthroscopy?
Shoulder arthroscopy is a procedure used to diagnose and treat shoulder conditions. During the surgery, a small camera (an arthroscope) is inserted into the shoulder joint through small incisions, allowing the surgeon to view and repair damaged tissues with specialised instruments. Compared to traditional open surgery, arthroscopy typically causes less pain and allows for a quicker recovery. This article explains the procedure, what to expect during the surgery, its benefits and risks, and the recovery process.
When is Shoulder Arthroscopy Recommended?
It is advised for patients experiencing persistent shoulder pain, limited range of motion, or are unresponsive to non-surgical treatments. Shoulder arthroscopy is commonly used to treat rotator cuff tears, labral tears, shoulder impingement syndrome, frozen shoulder, and shoulder instability.
Benefits of Shoulder Arthroscopy
Minimally Invasive: Arthroscopy uses smaller incisions compared to open surgery, resulting in less tissue damage and reduced post-operative pain.
Shorter Recovery Period: The procedure typically results in a faster recovery and an earlier return to work and routine activities.
Reduced Scarring: Smaller incisions mean less visible scarring, which is advantageous for cosmetic concerns.
Reduced Risk of Complications: The minimally invasive method lowers the risk of complications such as infection and bleeding, and the precision of the instruments helps prevent damage to surrounding tissues.
The Procedure: What to Expect?
Pre-procedure Preparation
Medical Evaluation
Medical evaluation begins with a thorough review of your health history and current conditions. The physical examination tests your shoulder’s range of motion, strength, and specific movement patterns that cause pain. A complete blood count, chest X-ray, and ECG may be required for patients over 50 or those with underlying health conditions.
Imaging Studies
X-rays provide initial views of bone structure and detect any arthritis or bone spurs within the shoulder joint. MRI scans show detailed images of soft tissues, including the rotator cuff tendons, labrum, and ligaments. CT scans may be ordered in cases where bone detail or complex shoulder anatomy needs closer examination.
Medication Adjustment and Fasting
Blood-thinning medications must be stopped 5 to 7 days before surgery as directed by your surgeon. Anti-inflammatory medications should be discontinued 7 to 10 days before the procedure. Food and drinks must be avoided for 8 hours before the scheduled surgery time. Clear liquids may be permitted up to 2 hours before the procedure
Step-By-Step Process
The shoulder arthroscopy procedure takes 1 to 2 hours, depending on the complexity of the repairs, and includes several steps.
Anaesthesia Administration
The procedure is performed under general anaesthesia for complete sedation or regional nerve blocks to numb the shoulder area, depending on the patient’s needs discussed during the pre-surgery consultation.
Making Incisions
The surgeon marks and creates small incisions around the shoulder, each 5 to 10mm in length, which serve as entry points for the arthroscope and surgical instruments. The incisions are strategically placed to avoid nerves and blood vessels.
Inserting the Arthroscope
The arthroscope is inserted through one incision, and the camera sends images to a monitor, allowing the surgeon to view inside the joint. This helps the surgeon identify and assess any damage to the shoulder joint.
Treatment and Repair
Through the incisions, specialised instruments are used to remove or repair damaged tissues, smooth bone surfaces, or fix torn ligaments and tendons. Real-time images help guide instrument placement and tissue manipulation while causing minimal damage to the surrounding tissues.
Closure and Dressing
The joint is thoroughly irrigated to remove any debris. Incisions are closed with sutures or surgical tape. Sterile dressings cover the incision sites, and the shoulder may be immobilised in a sling or brace.
Recovery After Shoulder Arthroscopy
Immediate Post-Operative Care
After surgery, patients are monitored in a recovery room until the anaesthesia wears off. Pain is managed with medication, and ice packs may be used to reduce swelling. Vital signs are checked to ensure the patient is stable before discharge.
Recovery Timeline
Recovery progresses through distinct phases, varying by individual and procedure type. The first few days focus on rest, pain management, and swelling control using ice and arm elevation, with a sling for protection. Physical therapy begins within the first week, introducing gentle exercises to prevent stiffness.
Through the following weeks, therapy intensifies to restore strength and range of motion. Most patients return to light activities within 1 to 2 weeks and resume normal activities within 4 to 6 weeks, though complete recovery may take several months depending on the repair.
Potential Risks and Complications
While shoulder arthroscopy is generally safe, there are a number of potential risks. Infection may develop at incision sites or within the joint, presenting as redness, swelling, pain, or fever. Nerve injury can cause temporary numbness, tingling, or weakness in the arm. Post-operative stiffness typically improves with physical therapy. Other rare complications include blood clots, bleeding, or anaesthetic reactions. The surgeon implements specific protocols to minimise these risks, and most patients recover without complications.
Conclusion
Shoulder arthroscopy offers a minimally invasive solution for diagnosing and treating various shoulder conditions. With smaller incisions, faster recovery, and fewer complications than traditional surgery, it is a suitable option for many patients. Learning about the procedure, its benefits, risks, and recovery process can help patients make informed decisions.
