Arthroscopic repair of a SLAP tear is a specialized shoulder procedure used for selected patients with injury to the superior part of the shoulder labrum. In my practice, I usually explain to patients that a SLAP tear is not simply “shoulder pain.” It is a specific injury pattern involving the upper part of the labrum, where the biceps tendon also attaches. Because of that, it can cause pain, clicking, weakness, reduced sports performance, and a feeling that the shoulder is not working properly.[1]
In Bangladesh, many patients with shoulder pain first assume the problem is a muscle strain, cervical pain, or general weakness. Sometimes that is true. But in some patients, especially younger active individuals, overhead workers, throwing athletes, and people with a past traction injury or dislocation, the pain may be related to a SLAP lesion.[1][2]
One important point I want Bangladeshi patients to understand is that not every SLAP tear needs surgery. Many patients improve with careful non-surgical treatment. Arthroscopic repair becomes more relevant when symptoms persist, function remains limited, and the diagnosis matches the patient’s history, examination, and imaging findings.[1][3]
What is a SLAP tear?
SLAP stands for superior labrum anterior to posterior. This means the tear affects the top part of the labrum, extending from the front to the back around the biceps anchor.
Why the labrum matters
The labrum is a ring of strong fibrous tissue around the socket of the shoulder. It helps deepen the socket and contributes to shoulder stability. The upper part is especially important because the biceps tendon attaches there.[1]
What happens when it tears
When this area is injured, the shoulder may become painful during certain movements, especially overhead activity, lifting, pulling, or forceful sports use. Some patients feel catching, popping, or a “dead arm” sensation.
What causes a SLAP tear?
I see several patterns that can lead to this injury.
Sudden trauma
A SLAP tear can happen after:
- a fall on an outstretched hand
- a sudden pull on the arm
- a road traffic injury
- lifting a heavy object unexpectedly
- shoulder dislocation or instability episode
Repetitive overhead stress
This is common in athletes and people whose work involves repeated overhead activity. Over time, repetitive strain can affect the superior labrum.[1][2]
Age-related labral wear
In some adults, especially over the age of 30 to 40, fraying or age-related change of the superior labrum may be seen on imaging. That does not always mean surgery is needed. This is why imaging findings must match the symptoms and examination.[1][3]
What symptoms can a SLAP tear cause?
Not every patient has the same pattern. Symptoms may overlap with other shoulder problems, which is why diagnosis requires care.
Common symptoms
Patients may report:
- deep shoulder pain
- pain during overhead movement
- clicking, popping, or catching
- discomfort when lifting objects
- reduced strength
- a feeling that the shoulder is not stable
- fatigue during sports or repeated arm activity
Symptoms in active and throwing patients
Throwing athletes may feel loss of velocity, pain late in throwing, or a sense of deadness in the arm. In Bangladesh, this may apply not only to competitive athletes but also to people who do repeated overhead work.
How do I suspect a SLAP tear?
I do not diagnose a SLAP tear based on pain alone. Many other problems can look similar, including rotator cuff disease, instability, biceps problems, and neck-related pain.
Clinical clues
I think more carefully about a SLAP lesion when a patient has:
- pain deep inside the shoulder
- pain with overhead activity
- a history of traction injury, fall, or sports stress
- clicking or mechanical symptoms
- associated instability features
- pain that is not explained well by rotator cuff disease alone
Overlap with nearby conditions
Some patients also have instability-related problems such as Bankarts Tear or broader pain patterns like Shoulder Pain and Pain Around the Neck. That is why I evaluate the whole shoulder and not just one possible diagnosis.
How is the diagnosis confirmed?
The diagnosis is based on the combination of history, examination, and imaging. No single finding should be used in isolation.
Physical examination
I assess:
- range of motion
- strength
- stability
- biceps-related pain
- labral stress signs
- scapular control
- rotator cuff status
- whether the neck could be contributing
Imaging
X-rays
X-rays do not show the labrum directly, but they help rule out fracture, arthritis, or other structural issues.
MRI or MR arthrogram
MRI, and sometimes MR arthrogram, is more useful for evaluating the labrum and related soft tissue. Even then, imaging must be interpreted carefully because labral changes may not always explain the symptoms.[1]
When is arthroscopic repair considered?
This is one of the most important parts of patient counseling. Not all SLAP tears should be repaired surgically.
Non-surgical treatment first
In many patients, the first treatment plan includes:
- activity modification
- physiotherapy
- range-of-motion work
- rotator cuff and scapular strengthening
- pain control under medical guidance
- correction of mechanics and posture
AAOS guidance also notes that initial treatment for SLAP tears is often non-surgical, and rehabilitation may continue for several months before deciding on surgery.[1]
Surgery becomes more relevant when
I consider arthroscopic repair more seriously when:
- symptoms remain significant despite structured non-surgical treatment
- the patient is young or active and has clear functional demands
- there are mechanical symptoms and instability-related findings
- imaging and examination support a repairable superior labral lesion
- the patient’s pain pattern matches a SLAP injury
- other shoulder conditions do not fully explain the symptoms
