Shoulder Ligament Rupture & Instability Treatment in London
Shoulder and upper limb conditions are common and can cause difficulties in everyday life. A shoulder ligament rupture commonly occurs alongside injuries to the shoulder capsule and labrum following a traumatic dislocation or repeated episodes of instability. Many patients who dislocate their shoulder also sustain damage to the labrum, a key stabilising structure that works closely with the shoulder’s ligament system. Problems can occur suddenly or develop over time, so it’s often best to seek assessment as soon as possible.
If your shoulder keeps slipping out of place, feels unstable, or you suspect ligament damage to the shoulder, this page will help you understand what is happening and what can be done.
Why Shoulder Ligaments Matter
The shoulder is the most mobile joint in the body. This mobility allows you to move freely, but it comes at the cost of stability. Stability is largely provided by soft tissues:
- Ligaments – strong bands that connect bone to bone
- The labrum – a ring of cartilage that deepens the socket
- Muscles and tendons – particularly the rotator cuff
When these structures are damaged, particularly through a shoulder ligament rupture, the joint can become unstable. This is what leads to shoulder instability and, in many cases, repeated dislocations.
Signs of Shoulder Ligament Rupture
A ligament injury in the shoulder can vary from a mild sprain to a complete rupture. Common signs include:
A sudden “pop” or tearing sensation at the time of injury
Pain, particularly with movement
A feeling that the shoulder is loose or slipping
Weakness or reduced control
Swelling or bruising after trauma
In more severe cases, the shoulder may fully dislocate and require urgent assessment and reduction by a trained clinician. Do not attempt to put a dislocated shoulder back into place yourself. Once the joint has been assessed and, if necessary, reduced, many patients can be treated without surgery through physiotherapy and a structured rehabilitation programme.
However, if you experience a traumatic shoulder injury, ongoing instability, or suspect your shoulder has dislocated, you should seek prompt medical assessment.
Symptoms of Shoulder Instability
Shoulder instability is not always obvious at first. Some patients do not have a full dislocation but describe a lack of confidence in the joint.
Recurrent dislocations or subluxations (partial dislocations)
A sensation of the shoulder “giving way”
Pain during overhead activity or sport
Clicking, catching, or grinding
Avoidance of certain movements due to fear of dislocation
If you are asking yourself, “Why does my shoulder keep dislocating?”, the answer is often damage or dysfunction affecting the structures that stabilise the shoulder. This may include ligament damage to the shoulder, injury to the labrum or shoulder capsule, bone loss following previous dislocations, or weakness and poor control of the muscles that help keep the joint stable.
Why Does My Shoulder Keep Dislocating?
If your shoulder keeps dislocating, the underlying cause is often damage to the ligaments, labrum or joint capsule that normally keep the ball of the shoulder securely within its socket. Once these stabilising structures have been stretched or torn, the risk of recurrent dislocations increases significantly.
Many patients who experience repeated dislocations have an associated Bankart lesion or other labral injury, making the shoulder increasingly unstable after each episode. Early assessment can help determine whether physiotherapy alone is appropriate or whether shoulder stabilisation surgery should be considered.
Common Causes
There are two main patterns of shoulder instability commonly seen in clinical practice:
- Traumatic instability – usually from a fall, sports injury, or collision. This often leads to a shoulder ligament rupture and labral tear.
- Atraumatic instability – develops gradually, often due to naturally lax ligaments or repetitive strain.
Sports such as rugby, football, and skiing commonly cause traumatic instability. You can learn more about traumatic shoulder injuries on our Shoulder Trauma page.
In traumatic cases, the shoulder most commonly dislocates forwards. This is known as an anterior dislocation.
Ligament, Labral and Bony Injuries
Ligament Injuries
Not all ligament injuries are the same. Understanding the type and severity of the injury helps guide the most appropriate treatment.
- Partial ligament tear – the ligaments are stretched or partially torn.
- Complete shoulder ligament rupture – the ligament is fully torn and can lead to significant instability.
Associated Injuries
A shoulder dislocation can also damage other structures that help keep the joint stable. These associated injuries are common and may influence both symptoms and treatment.
- Bankart lesion – a tear or detachment of the anteroinferior labrum, sometimes involving the attached shoulder capsule and ligaments.
- Hill-Sachs lesion – a compression defect (dent) in the humeral head caused when it impacts the edge of the shoulder socket during a dislocation.
These injuries frequently occur together. For example, a shoulder ligament rupture may occur alongside a Bankart lesion, while a Hill-Sachs lesion may also be present after a shoulder dislocation. Together, these injuries can contribute to ongoing instability and increase the risk of recurrent dislocations.
If your injury also involves the labrum, you may find our SLAP Tear page helpful.
How Shoulder Instability Is Diagnosed
Diagnosis begins with a detailed consultation. Mr Akhtar will ask about your symptoms, when they began, and how they affect your daily activities. This is followed by a physical examination to assess range of motion, strength and joint stability. Certain clinical tests can reproduce instability and help identify ligament damage or labral injury.
MRI and Imaging
Imaging is often required to confirm the diagnosis and plan treatment.
- X-rays – assess bone position and rule out fractures
- MRI scans – can show soft tissue injuries such as ligament tears and labral damage
- CT scans – used in more complex cases to assess bone loss
MRI is particularly useful in identifying a shoulder ligament rupture and associated injuries. MRI also helps identify associated injuries, such as Bankart lesions, SLAP tears and rotator cuff injuries, allowing the most appropriate treatment plan to be recommended.
Non-Surgical Treatment
Not every case of instability requires surgery. Many patients improve with non-operative care, such as:
- Physiotherapy to strengthen stabilising muscles
- Activity modification
- Pain management strategies
The aim is to restore control and reduce the risk of further dislocation. This approach is often appropriate for first-time dislocations or mild ligament damage.
If your shoulder continues to slip out of place despite physiotherapy or previous treatment, arranging a specialist assessment can help determine whether shoulder stabilisation surgery may offer a better long-term solution.
When Surgery Becomes Necessary
Surgery may be recommended if the shoulder continues to dislocate despite rehabilitation, there is a shoulder ligament rupture or capsulolabral injury causing ongoing instability, there is significant bone loss, or symptoms continue to limit everyday activities or sport. Your surgeon will also consider factors such as your age, activity level, and treatment goals when recommending the most appropriate approach.
Shoulder Stabilisation Surgery
The goal of surgery is to restore stability by repairing or reconstructing the structures that support the shoulder. Most shoulder stabilisation procedures are performed arthroscopically (keyhole surgery), allowing damaged ligaments and the labrum to be repaired through small incisions.
- Repairing the torn labrum (Bankart repair)
- Tightening stretched ligaments
- Addressing bone loss if present
Arthroscopic stabilisation is widely used because it allows surgery to be performed through smaller incisions. For patients with associated injuries, such as rotator cuff tears, these can often be addressed during the same procedure.

Frequently Asked Questions
What does a shoulder ligament rupture feel like?
Most patients describe a sudden pain with a popping sensation, followed by instability or weakness. Some also feel the shoulder slip out of place or notice difficulty moving the joint after the injury.
Can a torn shoulder ligament heal without surgery?
Some shoulder ligament injuries can improve with physiotherapy and a structured rehabilitation programme, particularly when the shoulder remains stable. However, surgery may be recommended if you experience recurrent instability, have a substantial capsulolabral or bony injury, or continue to have symptoms despite non-operative treatment.
Why does my shoulder keep dislocating?
Repeated shoulder dislocations are commonly caused by damage to the ligaments, labrum or other stabilising structures within the shoulder joint. Once these tissues have been stretched or torn, the shoulder becomes more prone to further dislocations and ongoing instability.
Can shoulder instability become permanent?
It can persist or recur if the underlying problem is not addressed. However, many patients improve with an appropriate rehabilitation programme or surgical treatment when needed. Early assessment can help identify the cause of instability and determine the most appropriate treatment to restore shoulder stability and reduce the risk of further dislocations.
Do I need an MRI?
Not always. The imaging required depends on your symptoms, examination findings and the nature of the injury. Following a shoulder dislocation or traumatic injury, X-rays are often used to assess the bones, while an MRI or MR arthrogram may be recommended if your specialist suspects damage to the ligaments, labrum or other soft tissues. In some cases, a CT scan may be used to assess bone loss and help plan treatment.
Can physiotherapy fix shoulder instability?
Physiotherapy can be an effective treatment for some patients with shoulder instability. However, the most appropriate treatment depends on factors such as your age, activity level, the severity of the injury, any associated structural damage, your risk of recurrent dislocation, and your treatment goals. In some cases, particularly when instability persists or recurs, surgical stabilisation may be recommended.
How long does recovery take after shoulder stabilisation surgery?
Recovery varies depending on the type of surgery performed, the severity of the injury and your rehabilitation programme. Physiotherapy plays an important role in restoring shoulder strength and stability. Mr Akhtar will monitor your recovery and advise when it is appropriate to return to work, driving, exercise and sporting activities.
What happens if shoulder issues are left untreated?
Repeated shoulder dislocations can cause further damage to the ligaments, labrum and surrounding bone. Over time, this may lead to ongoing instability, reduced shoulder function and early wear of the joint. Early assessment can help prevent further damage and determine the most appropriate treatment.
