Posterior Labral Tear Repair
A posterior labral tear is tear of the back (posterior) rim of the glenoid labrum, often from contact sports, bench press, a fall on an outstretched hand (FOOSH Injury), or seizures. A similar condition called Reverse Bankart lesion is a tear of the back-bottom (posterior–inferior) part of the glenoid labrum.
Both of these posterior labral tears can cause deep pain at the back of the shoulder, posterior instability (the ball of the humerus slips backward), clicking, and a sense that the shoulder might “slide out” during bench press, push-ups, tackles, or seizures/electric shock injuries.
Diagnosis consists of specialist examination, MRI arthrogram and/or CT scan. The treatment ranges from targeted physiotherapy to arthroscopic posterior labral (Reverse Bankart) repair, with bone repair procedures considered if there is glenoid bone loss.
What is a Posterior Labral Tear?
The shoulder’s glenoid labrum is a tough cartilage rim that deepens the socket and anchors the capsulolabral complex. Posterior labral tears commonly occur due to repetitive bench pressing, recurrent heavy weightlifting, contact impact, or a sudden posterior force. The shoulder may feel as if it wants to “slide out” backwards. This pattern can occur alone, or alongside other injuries such as a Reverse Bankart lesion (where there is a tear of the posterior-inferior labrum) or in anterior injuries like Bankart, bony Bankart, and Hill-Sachs (more typical with anterior dislocations).

Symptoms At a Glance
Patients with shoulder instability from posterior dislocation may present with the following symptoms:
Deep posterior shoulder pain often aggravated during pressing/pushing (bench press, push-ups)
Clicking, catching, or a sense the shoulder might slip backwards
Reduced power and endurance in overhead or horizontal press motions
Apprehension with the arm pushed forward across the body or in a loaded push position
Occasional subluxations or a “clunk” that self-reduces
Night discomfort lying on the affected side
When to Seek Urgent Care?
You might need to seek urgent care under a shoulder specialist or in the Accident and Emergency Department if there is:
A first-time dislocation (front or back) with visible deformity
Numbness/tingling, weakness, or a cold/pale limb after an episode
Severe pain and inability to move the arm after trauma (possible fracture/dislocation)
Posterior Labral Tear Treatment
How do Diagnose a Posterior Labral Tear?
Many patients who sustain a posterior shoulder dislocation may also sustain a Reverse Bankart lesion. The following procedures may help in diagnosing a Posterior Labral Tear and/or a Reverse Bankart Lesion.
History Taking & Examination by Our Specialist
Your sports shoulder specialist will take a
sports and injury history (contact sport, bench press, seizures) and
perform targeted test posterior apprehension/relocation manoeuvres,
load-and-shift, O’Brien test
other labral provocation manoeuvres (to assess for concomitant superior labrum involvement/SLAP)
Diagnostics and imaging
X-rays to screen for fractures and alignment.
MRI or MRI arthrogram to visualise the posterior labrum, capsule, and any concurrent lesions. Arthrogram improves visibility of the labrum and capsulolabral complex.
Where glenoid bone loss is suspected, advanced imaging helps surgical planning.
What are my Treatment Options for a Posterior Labral Tear?
Most patients start with non-surgical care; surgery is considered when symptoms persist, or performance goals require it.
Posterior Labral Tear Conservative Treatment (non-surgical) - often preferred
Physiotherapy/rehabilitation: scapular control, rotator-cuff endurance, posterior shoulder flexibility, proprioception, and kinetic-chain optimisation.
Technique & load modification: especially for bench press/push patterns; progress under guidance.
Short course of analgesia as advised; selective image-guided injections can aid pain control during rehab.
It is important to note that many recreational athletes improve with structured rehab.
Posterior Labral Tear Surgical Treatment:
Surgery is considered for persistent symptoms, recurrent instability, high-demand sport, or when imaging shows structural risk factors.
Posterior Labral Tear
Back of labrum
Pressing/ contact, posterior force, seizures
Posterior laxity; may coexist with reverse Bankart
SLAP Tear
Superior labrum at biceps anchor
Overhead sport/ traction
Biceps symptoms, top-labrum pain
Typical Approach
Scenario
Arthroscopic posterior labral (Reverse Bankart) repair ± capsular plication
Symptomatic Reverse Bankart without bone loss
Consider posterior bone-block/graft procedure
Posterior labral tear with significant posterior bone loss
Combined stabilisation (e.g., posterior repair + address anterior injury; Remplissage/Latarjet if indicated for anterior lesions)
Combined anterior + posterior pathology
Quick Comparison of the Common Shoulder Lesions
Anterior dislocation
Bankart
Antero-inferior labrum
Hill-Sachs, Bony Bankart
Common Associated Injury
Where is the tear?
Typical Mechanism
Posterior bone loss possible
Reverse Bankart
Posterior-inferior labrum
Posterior dislocation/ subluxation
Recovery & Return to Sport
Sling/ immobilisation for ~2–4 weeks depending on repair and tissue quality with early protected motion under therapist guidance.
Rehab phases: protected motion —> active assisted movements —> progressive strength/endurance exercises —> contact/overhead control and sport-specific drills.
Modified desk work can often resume in 1–2 weeks.
Return to non-contact sport typically begins once strength and control benchmarks are met; contact/overhead return is usually 4–6 months, depending on procedure and progress in shoulder rehab.

Who Should Seek Consultation for Posterior Labral Tear/ Reverse Bankart Lesion?
Adults with recurrent posterior slips/subluxations or persistent apprehension in push/press positions
Athletes in rugby, basketball, weightlifting/CrossFit, swimming with persistent pain or performance loss
Imaging mentioning Reverse Bankart, posterior labral tear, or glenoid bone loss

Frequently Asked Questions
-
They’re closely related; Reverse Bankart typically refers to a posterior-inferior detachment seen with posterior dislocation. Many clinicians group it under the umbrella of posterior labral tears.
-
Heavy or poorly controlled bench press/push loading can stress the back of the labrum, especially if there is underlying laxity or a prior injury.
-
No. Many improve with targeted physiotherapy and sport-specific modifications. Surgery is considered for recurrent instability, persistent pain, performance-limiting symptoms or when imaging shows structural risk factors.
-
An MRI arthrogram offers the clearest view of the capsulolabral complex and associated injuries.
-
Usually via arthroscopic repair using small suture anchors to reattach the posterior labrum; capsular plication may be added to address laxity.
-
That suggests combined (bidirectional) instability. Your surgeon may address both sides in the same setting—e.g., posterior repair plus anterior remplissage/Latarjet if indicated.
-
In the private clinic pathway, you can book directly with a specialist. (Insurance or employer plans may have their own requirements.)
