Key Takeaways
- Shoulder instability happens when the ligaments and labrum that hold the shoulder in its socket are torn or overly loose, allowing the joint to dislocate or feel like it is giving way.
- Instability can come from a single traumatic dislocation or from ongoing looseness that develops without a specific injury.
- Non-surgical treatment, including bracing and a structured physical therapy program, is often the first step and can be enough for many patients.
- Surgical repair becomes the better path when there is a structural tear, repeated dislocations, or instability that keeps interfering with work and daily activity despite therapy.

What Causes Shoulder Instability?
The shoulder is the most mobile joint in the body, which also makes it more prone to slipping out of place than other joints. Stability depends on a network of soft tissue, including the labrum, a ring of cartilage around the shoulder socket, along with the surrounding ligaments and joint capsule. When these structures are torn or naturally too loose, the shoulder can partially or completely dislocate.
Shoulder instability generally develops in one of two ways:
- Traumatic instability: A forceful injury, such as a fall, sports collision, or car accident, can tear the labrum away from the socket. This tear is commonly called a Bankart lesion. Once this 'bumper' is damaged, the shoulder often becomes more prone to dislocating again with less force than the original injury required.
- Atraumatic instability: Some people have naturally loose ligaments throughout their body, sometimes described as being hypermobile. Without a single defining injury, the shoulder capsule may stretch over time, and the joint can begin slipping out of place during everyday movements.
Recognizing the Types of Shoulder Instability
Instability can range widely in severity:
- A subluxation is a partial slip, where the joint shifts out of place and then moves back on its own.
- A dislocation is a complete separation, where the joint surfaces come fully apart and often require a doctor's help, or manual repositioning, to reduce.
- Recurrent instability describes a pattern of repeated subluxations or dislocations, which can happen with less and less force over time as the shoulder's stabilizing structures continue to loosen.
Non-Surgical Treatment for Shoulder Instability
For many patients, especially those with a first-time dislocation or milder ligament laxity, non-surgical care is the appropriate starting point. This typically includes:
- A period of sling immobilization to allow the shoulder to calm down after an acute dislocation.
- A structured physical therapy program focused on strengthening the rotator cuff and shoulder-stabilizing muscles.
- Activity modification to avoid positions that provoke instability while the shoulder regains strength and control.
Patients with atraumatic, or hypermobility-related, instability in particular often respond well to a dedicated therapy program, since the underlying issue is more about muscle control than a structural tear.
When Surgical Treatment Is the Better Path
Surgery becomes the recommended option when instability is caused by a clear structural tear, such as a Bankart lesion, or when repeated dislocations continue to occur despite a genuine effort with therapy. Surgery is also considered for patients whose instability is significantly interfering with work, sports, or basic daily tasks like reaching overhead or carrying groceries.
Dr. Kamineni's approach to shoulder instability repair is tailored to the specific structural findings on your exam and imaging. Depending on the extent of the tear and any associated bone loss, treatment may involve reattaching the torn labrum, tightening the stretched joint capsule, or, in cases with significant bone loss, restoring the socket's normal anatomy with a bone graft procedure. You can review this approach in more detail on the shoulder instability surgery and dislocation page.
Non-Surgical Care vs. Surgical Repair
| Factor | Non-Surgical Treatment | Surgical Repair |
|---|---|---|
| Best suited for | First-time dislocation, mild laxity, atraumatic causes | Structural tear (Bankart lesion), recurrent dislocations, significant bone loss |
| Main approach | Sling, physical therapy, activity modification | Labral repair, capsule tightening, or bone graft procedure depending on findings |
| Typical timeline | Several weeks to months of guided therapy | Weeks of sling protection followed by a structured rehabilitation program |
| Best for patients who | Have not had repeated dislocations and respond to therapy | Continue to have instability despite therapy or have a clear structural injury |
Get Your Shoulder Evaluated Before Instability Gets Worse
Repeated shoulder dislocations do more than interrupt your day. Each episode can cause additional wear on the joint, making future dislocations more likely and potentially raising the long-term risk of arthritis. Dr. Srinath Kamineni brings specialized, fellowship-level training in shoulder instability repair to patients throughout Mount Carmel and Olney, IL.
If your shoulder has dislocated more than once, or if it feels loose or unreliable during work or daily activity, schedule an appointment with Dr. Kamineni to determine whether therapy or surgical repair is the right next step for you.
Frequently Asked Questions
How do I know if my shoulder instability needs surgery?
The decision depends on the underlying cause and how your shoulder has responded to treatment so far. A structural tear like a Bankart lesion, ongoing dislocations despite therapy, or significant bone loss on the socket are all signs that surgery may offer better long-term stability than non-surgical care alone. An exam with imaging is the clearest way to know which category applies to you.
What is a Bankart lesion?
A Bankart lesion is a tear of the labrum, the ring of cartilage around the shoulder socket, most often caused by a forward, or anterior, shoulder dislocation. Once this tissue is torn, the shoulder often loses some of its natural stability, which is why repeated dislocations become more likely without treatment.
Will physical therapy alone fix my shoulder instability?
It depends on the cause. Instability related to general ligament looseness, without a structural tear, often responds well to a dedicated physical therapy program focused on strengthening the muscles that stabilize the shoulder. However, instability caused by a torn labrum typically does not fully resolve with therapy alone, since the torn tissue itself needs to be repaired.
What does recovery look like after shoulder instability surgery?
Recovery generally starts with a period of sling support to protect the repair, followed by a structured rehabilitation program to gradually restore motion and then rebuild strength. Specific timelines vary based on the type of procedure performed and the extent of the original injury.
