Are Your Symptoms Affecting Your Quality Of Life?
Consult our MOH-accredited shoulder specialist for an accurate diagnosis & personalised treatment plan.
SLAP (superior labrum anterior to posterior) repair is a surgical procedure used to treat tears in the superior labrum, a ring of cartilage surrounding the shoulder socket (glenoid). This type of tear affects the labrum from the front (anterior) to the back (posterior) and can compromise the stability and function of the shoulder joint. SLAP repair typically involves reattaching the torn cartilage to the bone, helping restore shoulder stability and reduce pain.
A SLAP repair is recommended when conservative management fails to alleviate symptoms or when the tear leads to functional impairment. Common indications include:
SLAP repair has several advantages and addresses both the short- and long-term functional needs of the patient. The benefits include:
SLAP repair can be performed using two main surgical approaches:
This method involves inserting a small camera (arthroscope) and surgical tools through small incisions to visualise and repair the tear. The labrum is reattached to the glenoid using sutures or anchors. This minimally invasive approach results in smaller scars, reduced infection risks, and faster recovery times compared to open surgery.
This procedure is performed through a larger incision, providing direct access to the shoulder joint. This technique is typically reserved for complex cases or when additional repairs, such as rotator cuff repair, are required. Although it allows for better joint visualisation, it involves a longer recovery period and a higher risk of complications than arthroscopic repair.
Before undergoing SLAP repair, patients undergo comprehensive preoperative assessments to ensure they are fit for surgery.
The surgeon reviews the patient’s medical history, focusing on previous shoulder injuries and health conditions, such as diabetes or hypertension, which could impact surgery or recovery. This helps ensure the patient is fit for the procedure and anaesthesia.
A thorough physical exam assesses the shoulder’s stability, range of motion, and pain points. The surgeon looks for signs of instability, such as the shoulder slipping or feeling weak, and evaluates movement limitations, including difficulty raising or rotating the arm.
MRI or ultrasound scans confirm the presence and extent of the SLAP tear, providing detailed visuals of the joint. These tests also help identify other injuries, such as rotator cuff tears or biceps tendon damage, which may need to be addressed during surgery.
Patients may need to stop medications like blood thinners before surgery to reduce bleeding risks. Other prescribed medications will be reviewed to determine if adjustments are needed for a safe procedure.
Patients scheduled for general anaesthesia must fast for 6 to 8 hours before surgery to prevent complications, such as aspiration, which occurs when stomach contents enter the lungs during anaesthesia.

The SLAP repair procedure generally follows these steps:
General anaesthesia is used to keep the patient unconscious and pain-free throughout the procedure. In some cases, a regional nerve block is used to numb the shoulder and arm, sometimes combined with sedation.
In arthroscopic repair, small incisions are made to insert the arthroscope and instruments. In open surgery, a larger incision is made to access the joint directly, which may be necessary for complex tears or if additional repairs are required.
The surgeon examines the joint to confirm the location and extent of the SLAP tear, identifying any additional damage. Once the tear is identified, small anchors with attached sutures are placed into the glenoid bone. These anchors provide secure points for reattaching the labrum to its original position.
The surgeon pulls the torn labrum back into place and secures it using the sutures attached to the anchors.
Once the labrum is reattached, the small incisions are closed using stitches or surgical tape. A sterile dressing is applied over the incisions to protect the surgical site from infection and promote healing.
Following surgery, a structured post-operative care and rehabilitation programme is necessary for healing and restoring function.
After surgery, the arm is immobilised in a sling for several weeks to protect the repair. Pain management may include prescribed medications or nerve blocks to alleviate discomfort. Patients must keep the surgical site clean and dry to prevent infection, following detailed wound care instructions provided.
Recovery from SLAP repair typically spans several months and follows a phased approach. The arm remains in a sling for the first 4 to 6 weeks, during which passive motion exercises are introduced to prevent stiffness. From 6 to 12 weeks, patients begin active exercises to restore mobility. Strengthening exercises follow between 3 and 6 months, focusing on rebuilding shoulder strength and stability. Full recovery, including the ability to return to sports or heavy activities, is expected within 6 to 12 months, with regular follow-ups to monitor progress and address any complications.
While SLAP repair is generally safe, some risks include infection at the incision site and stiffness leading to restricted shoulder movement. Rare complications include nerve injury during surgery and reactions to anaesthesia, both of which are uncommon but may impact recovery.

In some cases, small SLAP tears may improve with rest, physiotherapy, and anti-inflammatory medications. However, more severe tears often require surgery, especially if the patient experiences ongoing pain, instability, or functional limitations.
Most patients regain full shoulder function with proper rehabilitation, but some may experience mild residual stiffness or occasional discomfort.
The timeline for returning to work depends on the nature of the job. Sedentary jobs may be resumed within a few weeks, but jobs requiring heavy lifting or overhead activity may take several months, following the surgeon’s clearance.
