Why Does Your Shoulder Still Feel Unstable After an Injury?

The shoulder is built for movement, but that mobility also means it relies heavily on ligaments and other soft tissues for stability. A fall, sports injury, direct impact, or shoulder dislocation can stretch or tear these supporting structures.
Sometimes the pain and swelling improve, yet the shoulder still feels loose, weak, or as though it might slip out of place. This may indicate that the structures responsible for keeping the joint stable have been injured.
At Liberty Orthopaedic Clinic, Dr Lee Eu Jin assesses shoulder injuries to determine which structures are affected and whether treatment may involve rehabilitation, activity modification, or surgical management.

What Is a Shoulder Ligament Tear?

Ligaments are strong bands of connective tissue that connect one bone to another and help stabilise a joint.
In the shoulder, several ligaments work alongside the joint capsule, labrum, tendons and surrounding muscles to maintain stability while allowing a wide range of movement.
A shoulder ligament tear occurs when a ligament is stretched beyond its normal capacity and some or all of its fibres are damaged.
The injury can range from a mild sprain to a complete tear and may occur alongside other shoulder injuries.

Which Ligaments Can Be Injured in the Shoulder?

The shoulder is made up of several joints and supporting structures, which means different ligament injuries can occur depending on how the shoulder is injured.

Glenohumeral Ligaments

The glenohumeral ligaments help stabilise the main ball-and-socket joint of the shoulder.
They can be stretched or damaged when the shoulder dislocates or moves beyond its normal range.

Acromioclavicular (AC) Joint Ligaments

The AC joint is located where the collarbone meets the highest point of the shoulder blade.
A fall directly onto the shoulder can injure the ligaments around this joint, resulting in an AC joint sprain or separation.

Coracoclavicular Ligaments

These ligaments connect the collarbone to part of the shoulder blade called the coracoid.
They can also be damaged during more significant AC joint injuries and contribute to the stability of the collarbone.

What Causes a Shoulder Ligament Tear?

Shoulder ligament injuries commonly result from trauma or movements that force the joint beyond its normal range.
Possible causes include:
  • Falling directly onto the shoulder
  • Falling onto an outstretched hand
  • Shoulder dislocation
  • Direct impact during contact sports
  • Sudden forceful movements
  • Sports involving tackling, throwing or overhead activity
  • Road traffic accidents
  • Other traumatic injuries
Previous shoulder dislocations may also increase the likelihood of recurrent instability in some patients.

What Does a Torn Shoulder Ligament Feel Like?

Symptoms depend on which ligament has been injured and whether other shoulder structures are also affected.
Possible symptoms include:
  • Shoulder pain
  • Swelling or bruising
  • Tenderness around the joint
  • Pain when lifting or moving the arm
  • Reduced range of movement
  • Weakness
  • A feeling of looseness or instability
  • Clicking or catching sensations
  • A sensation that the shoulder may slip or pop out of place
With an AC joint injury, pain and tenderness may be concentrated around the top of the shoulder. More significant injuries may also alter the appearance or position of the joint.

Can a Shoulder Dislocation Tear the Ligaments?

Yes. A shoulder dislocation occurs when the head of the upper arm bone moves out of its normal position within the shoulder socket.
Because considerable force may be involved, a dislocation can stretch or damage the ligaments and joint capsule that normally keep the shoulder stable. Other structures, including the labrum, cartilage, bone, nerves or tendons, may also be injured.
After the shoulder has been put back into position, it is therefore important to consider the underlying injury rather than assuming the problem has been completely resolved.

Why Does My Shoulder Keep Feeling Like It Will Pop Out?

A shoulder that repeatedly feels as though it may slip out of place may be experiencing shoulder instability.
This can develop after a previous dislocation or traumatic injury when the supporting tissues have been stretched or damaged.
Some people experience a complete repeat dislocation. Others may have a partial slipping of the joint, known as a subluxation, or simply feel that the shoulder is unreliable in certain positions.
Instability can be particularly noticeable when the arm is raised, rotated backwards, or used during overhead activities and sports.

Is a Shoulder Ligament Tear the Same as a Rotator Cuff Tear?

No. Although both can cause shoulder symptoms, they involve different structures.
Ligaments connect bone to bone and contribute to joint stability.
Tendons connect muscle to bone. The rotator cuff is a group of muscles and tendons surrounding the shoulder joint, so a rotator cuff tear is a tendon injury rather than a ligament tear.
It is possible for different shoulder structures to be injured during the same traumatic event, which is why identifying the source of symptoms is important.

How Serious Is a Shoulder Ligament Tear?

Ligament injuries may be described according to the extent of damage.

Grade 1 – Mild sprain
The ligament has been stretched but remains intact.

Grade 2 – Partial tear
Some ligament fibres have torn, which may cause greater pain, swelling and loss of stability.

Grade 3 – Complete tear
The ligament is completely torn and may no longer provide its usual level of support.

The grade of injury is only one part of the assessment. The specific ligament involved, degree of instability, associated injuries, symptoms and activity requirements also influence treatment decisions.

How Is a Shoulder Ligament Tear Diagnosed?

Assessment usually begins with a discussion of how the injury occurred, where the pain is located, and whether there have been episodes of dislocation or instability.

The shoulder may be examined for:

  • Tenderness
  • Swelling
  • Range of movement
  • Strength
  • Joint stability
  • Signs of associated injury

Imaging may also be recommended depending on the suspected injury.

X-rays can assess the position of the joint and identify fractures or changes around the AC joint.

MRI scans may provide further information about soft-tissue structures, including the ligaments, labrum and tendons.

Other imaging may be considered depending on the injury.

Can a Torn Shoulder Ligament Heal Without Surgery?

Some shoulder ligament injuries can be treated without surgery, particularly when the joint remains sufficiently stable and symptoms improve with rehabilitation.

Non-surgical treatment may include:

  • Temporary activity modification
  • Support or immobilisation during the early stage when appropriate
  • Pain management
  • Physiotherapy
  • Exercises to restore movement
  • Strengthening of the muscles around the shoulder
  • Gradual return to normal activities or sport

The appropriate approach depends on the ligament involved and the severity of the injury.

When Might Surgery Be Considered for a Shoulder Ligament Injury?

Surgery is not required for every shoulder ligament tear.

It may be considered when:

  • Shoulder instability persists despite rehabilitation
  • Recurrent dislocations occur
  • The shoulder repeatedly slips or gives way
  • There is a significant traumatic ligament injury
  • Other structures within the shoulder are also damaged
  • Symptoms continue to interfere with work, sport or daily activities

The procedure considered will depend on the structures involved and the nature of the instability or injury.

Can Arthroscopic Surgery Be Used for Shoulder Instability?

Some shoulder conditions can be treated using arthroscopic, or keyhole, surgery.

During arthroscopy, a small camera and surgical instruments are inserted through small incisions around the shoulder. Depending on the injury, this approach may be used to assess and treat damaged structures contributing to instability.

Not every shoulder ligament injury requires arthroscopic surgery. Whether surgery is appropriate depends on the diagnosis, severity of instability, associated injuries and individual circumstances.

How Long Does a Shoulder Ligament Tear Take to Recover?

Recovery varies considerably depending on the type and severity of the injury.

Factors that can affect recovery include:

  • Which ligament or structures are injured
  • Whether the tear is partial or complete
  • Whether a dislocation occurred
  • Whether other structures were damaged
  • Whether surgery is required
  • Individual rehabilitation progress
  • Work and sporting requirements

A gradual return to activity is usually important. Returning to contact or overhead sports before sufficient movement, strength and stability have been restored may increase the likelihood of another injury.

When Should You See an Orthopaedic Surgeon for a Shoulder Injury?

Consider an orthopaedic assessment if:

  • Shoulder pain persists following an injury
  • The shoulder has dislocated
  • You notice a change in the shape of the shoulder after a fall
  • Movement remains restricted
  • The shoulder repeatedly feels loose or unstable
  • The shoulder slips partially or completely out of position
  • Symptoms prevent you from returning to work, exercise or sport

An assessment can help determine whether the symptoms are related to a ligament injury, instability, or another shoulder condition.

Frequently Asked Questions About Shoulder Ligament Tears

Can you move your arm with a torn shoulder ligament?

It may still be possible to move the arm with a ligament injury. The amount of movement and discomfort varies according to the ligament involved, severity of the injury and whether other shoulder structures are affected.

Can a shoulder ligament tear heal on its own?

Some ligament injuries can improve with non-surgical treatment and rehabilitation. More significant injuries associated with persistent instability or recurrent dislocation may require further treatment.

What is the difference between a shoulder sprain and a ligament tear?

A sprain is an injury to a ligament. Mild sprains involve stretching of the ligament, while more significant sprains can involve partial or complete ligament tears.

Does a shoulder dislocation always cause ligament damage?

A dislocation can stretch or damage the ligaments, joint capsule and other structures, but the extent of injury varies. An assessment can help determine what was damaged during the dislocation.

Why does my shoulder keep dislocating?

Recurrent dislocation can occur when the structures responsible for shoulder stability have been damaged or stretched following an earlier injury. Other factors may also contribute, so repeated instability should be assessed.

Does Your Shoulder Still Feel Unstable After an Injury?

A shoulder that continues to feel loose, slips out of position, or repeatedly gives way may have an underlying injury affecting its stability.
