Shoulder Labral Tears: Symptoms, Diagnosis, Treatment
The shoulder labrum or glenoid labrum is like a soft, fibrous “bumper ring” that lines the rim of your shoulder socket (the glenoid fossa or glenoid cavity). Think of it as the shoulder’s version of a suction cup — it deepens the socket, helps centre the ball of the upper arm bone (humerus), and creates a tight seal that keeps the joint stable. It’s also an important anchor point for key shoulder ligaments and the tendon of the biceps muscle, which attaches right into it.
When the labrum is torn or frayed, the shoulder can lose some of its built-in stability. This means the ball can shift or “translate” more in the socket, sometimes irritating other structures like tendons or bone along the way.
Labral injuries come in all shapes and sizes — from tiny, harmless tears that cause little to no symptoms, to larger tears that may occur after a shoulder dislocation and make the joint feel unstable. Because the labrum is made of cartilage with very little blood supply, it doesn’t heal easily on its own.
The good news? Most labral tears don’t need surgery. Many people regain full, pain-free function with the right physiotherapy program that focuses on restoring strength, control, and shoulder stability.

Different Types of Labral Tears
There are a number of different types of shoulder labral tears, and the type of labral tear can make a big difference in how they feel and how they’re managed. The main types include:
SLAP Tears (Superior Labrum Anterior to Posterior)
These occur at the top of the shoulder socket, where the biceps tendon attaches to labrum. They’re common in people who do a lot of overhead or throwing activities — think baseball pitchers, swimmers, or tradies working overhead. SLAP tears can cause pain at the front or top of the shoulder, often with clicking or a sense of weakness
Bankart Lesions/Reverse Bankart Lesions
Found at the front and lower part of the labrum, these tears often happen after a shoulder dislocation. Reverse Bankart Lesions is a far less common injury which occur after a posterior shoulder dislocation, when the ball slips backwards out of the socket. In some cases, these tears can lead to instability, where there dislocation recurs during activity.
Posterior Labral Tears
Less common, these occur at the back of the socket, sometimes from repetitive loading or a fall onto an outstretched arm or elbow. They may cause deep pain or a catching sensation during pushing or rotational movements.
Degenerative Labral Tears
These are age-related fraying that develop gradually over time (like wrinkles on the inside). They’re common in adults over 40 and often show up on scans even when there are no symptoms. In many cases, they’re a normal part of shoulder ageing rather than a serious injury and are suggested to be present in as much as 55% to 75% of asymptomatic shoulders in people aged 45-60 years. Further to that, some studies have shown the incidence of labral injuries in a cohort of symptom-free non-athletic young adults is 9%, whilst in symptom-free contact sport athletes in a similar demographic may be as high at 25%.
No single symptom or test can confirm a shoulder labral tear. Clinicians look for a pattern across your history, movement, strength, stability, and use specific tests to assess the labrum and its attachments – with imaging used only if needed.

Symptoms of a Shoulder Labral Tear
Every labral tear in the shoulder is different, and their presentation often overlaps with other shoulder issues. The nature of the symptoms will depend on the size, locations and cause of the tear – gradually developing tears may not cause any pain, whereas traumatic or unstable labral tears can be painful and associated with instability. The symptoms are often felt as a deep, dull ache, often associated with a sharper pain during provocative movements.
Common signs and symptoms of labral tears include:
- Pain at the front, top or back of shoulder and deltoid region might be present, depending on the location of the tear and subsequent dysfunction to the shoulder
- Clicking, catching or popping sensations occurring during movement
- Apprehension, or the sensation of instability/looseness can be a sign of an unstable labral tear. Bankart lesions caused by shoulder dislocations are often, but not always, associated with recurrent feelings of instability or slipping
- Pain with activity, especially overhead or when reaching out and across body
- Loss of power, especially when reaching overhead or throwing
How Are Shoulder Labral Tears Diagnosed?
The diagnosis of a shoulder labral tear can be a bit like detective work as most common presentations overlap with other shoulder conditions, such as rotator cuff tendinopathy or subacromial pain syndrome. To further challenge things, reliance on imaging to provide the answer is often misled, due to labral tears being found in many adults – especially those over 40 – have labral frays and tears that are completely asymptomatic, thus potentially being unrelated false positives! Because of this, a thorough clinical assessment is more important than reliance on scans alone.
Clinical assessment will start with a detailed history, asking how and when the symptoms began, and how they might have developed since them. Then a series of physical tests that assess movement, strength, stability and structure will be performed to inform the clinical on likely causes of the shoulder pain.
As MRI and MR arthrograms do not always match clinical symptoms, these studies are typically reserved for cases where instability or large trauma is suspected, or when symptoms do not improve with conservative management.

Treatments For Shoulder Labral Tears
The good news is that most shoulders with a labral tear can be restored to full, pain-free function with the right combination of exercises, load management and physiotherapy-guided rehabilitation. And even in cases with recurrent instability and surgery is sometimes required to return successfully to high-risk activities and contact sports, effective and thorough rehabilitation can lead to a return to activity and sport with good long-term outcomes.
Load Management and Education
Temporary modification to activity is often required to allow the joint to settle down in order to successfully rehabilitate the injury.
Rehabilitation and Conservative Management
Physiotherapy is the first-line treatment for most shoulder labral injuries. These programs need to be highly individualised, dependent on the nature of the injury, as well as considering concurrent injuries, inflammation/pain, changes to strength control, and other individual factors such as age, lifestyle and goals.
This programs generally progress from achieving pain-free mobility and activation work to strength, power and sport-specific tasks. Part of the rehabilitative process involved restoring strength to the stabilising muscles, a process that may take 6-12 weeks to see significant improvements, although more complex cases, athletes and those with high demands may require a longer, structured period of rehabilitation.
When Is Surgery Considered?
Surgery is generally reserved for significant structural instability, recurrent dislocations, or persistent pain that doesn’t respond to several months of well-supervised rehabilitation. The most common procedures performed are arthroscopic labral repair for most labral tears, biceps tenodesis for SLAP tears, or latarjet for bankart injuries for those who do sports or activities that place them at a high risk of recurrence.
Rehabilitation remains the cornerstone of recovery following surgery, facilitating the return of range of motion, strength, control and confidence before returning to sport and function.
As many as 70-85% of labral tears can be rehabilitated to good outcomes with non-operative treatment alone, particularly in cases with degenerative or small injuries. Ultimately, the focus often is not on “healing the tear”, but rather on optimising shoulder function and in most cases, physiotherapists focus on function rather than structure and imaging to restore pain-free function and return to what you love doing safely and confidently.
