What are the overall rates of complications following shoulder stabilization surgery?

General post-operative surgical risks, such as infection, joint stiffness, and bleeding, are low, occurring in less than 1% of cases for each complication. Total specialized complication rates vary by surgical technique; arthroscopic Bankart repairs have a complication rate under 5%, whereas the more intricate open Latarjet procedure has a complication rate ranging from about 30% (mostly minor) in high-volume medical centers.

What is the risk of recurrent shoulder dislocation after an arthroscopic Bankart repair?

An arthroscopic Bankart repair carries a recurrent instability risk of 6.7% within a 5-year short-term window. Over a long-term period (10 years or more), the recurrence rate can increase up to 20.9% in cohorts who suffered unrecognized pre-operative glenoid bone loss that should have been addressed via a Latarjet stabilization instead.

What are the specific complications associated with the Latarjet procedure?

Due to its mechanical complexity, the Latarjet procedure presents unique structural risks, including hardware-related complications (screw fracture, migration, or tissue irritation) ranging from 0% to 16%, and non-union of the transferred coracoid bone graft occurring in 5% to 8% of cases. Long-term follow-up at 5 years also reveals an 8% to 42% risk of degenerative joint osteoarthritis.

Which procedure carries a lower risk of re-dislocation: Bankart or Latarjet?

The Latarjet bone transfer procedure carries a significantly lower recurrence risk of just 1% to 5%, representing the most stable option among all shoulder stabilization techniques. Conversely, arthroscopic Bankart repairs show a higher failure and recurrence profile, ranging from about 16% at 10+ years depending on the timeline and patient demographic.

How does patient age affect the risk of post-operative failure?

An age under 20 years at the time of surgery is statically identified as the strongest predictor of surgical failure and re-dislocation after an arthroscopic Bankart repair. This demographic risk is highly relevant among collision athletes such as football players, wrestlers, and martial artists.

What is the most common diagnostic error leading to recurrent shoulder dislocations?

The most common surgical misstep is performing a soft-tissue Bankart repair on a shoulder with glenoid bone loss exceeding 20%. Relying exclusively on an MRI can lead to this error, as standard MRI scans underestimate the true volume of bone loss in some cases. A high-resolution 3D CT scan is mandatory pre-operatively to properly classify the pathology.

Is post-operative shoulder stiffness a permanent complication?

Temporary post-operative stiffness occurs in roughly 10% of standard shoulder surgeries. This is a typical physiological response during the early healing phases and generally resolves within 3 months of starting a structured physical therapy protocol. Additionally, Latarjet procedures specifically involve a 10% to 15% long-term reduction in external rotation.

Is there a significant risk of permanent nerve damage during stabilization?

Peripheral nerve damage (most commonly affecting the axillary nerve) or major neurovascular complications are extremely rare. When they do happen, they are usually temporary and stem from tissue traction during surgery rather than nerve transection. This risk is primarily associated with the surgeon's specialized learning curve.

What symptoms indicate an emergency post-operative complication?

Patients must contact their surgeon immediately if they develop any of the following warning signs: redness, warmth, or fluid drainage from the wound (infection), a fever over 38.5°C after day 3, persistent numbness or sudden weakness in the fingers/hand (nerve compression), sudden sharp pain at rest (screw fracture or intra-articular failure), or a feeling of shoulder instability after week 6.

How can a patient actively minimize their risk of post-operative complications?

Risks are minimized by insuring a 3D CT scan is conducted before surgery, electing a Latarjet procedure if bone loss exceeds 20%, ensuring the surgeon has a high lifelong volume of shoulder procedures, starting physical therapy by the first or second post-operative day, and strictly avoiding contact sports until completing a direct 4-to-5-month surgical evaluation.

Complications Of Shoulder Dislocation Surgery - American Center For Knee And Shoulder Surgeries 2026

Surgical stabilization for recurrent shoulder dislocation achieves excellent outcomes in most cases. However, overlooking potential complications leaves patients making uninformed choices and delays necessary assistance when signs of deviation from the normal recovery path appear. This article details the Complications of Shoulder Dislocation Surgery associated with shoulder dislocation surgery.

What Are the Complications of Shoulder Dislocation Surgery?

Complications of shoulder dislocation surgery fall into two categories: general complications shared by all shoulder surgeries—such as infection, stiffness, and bleeding (each occurring in less than 1% of cases)—and specific complications native to the type of procedure. A Bankart repair carries a long-term recurrent dislocation risk of about 16%, while the Latarjet procedure carries a hardware/screw complication risk ranging from 0% to 16%.

Re-operation after general arthroscopic shoulder surgery is uncommon. However, procedures addressing shoulder instability carry a relatively higher rate linked directly to recurrent dislocations rather than a failure of the surgical technique itself. Understanding this distinction is crucial; technical surgical success does not eliminate the possibility of a future dislocation if the patient returns to collision sports prematurely. Complications are also categorized timeline-wise into early complications (occurring within the first few weeks) and late complications (such as osteoarthritis or recurrent instability).

Complications of the Arthroscopic Bankart Procedure

The primary complication of an arthroscopic Bankart repair is a recurrent dislocation, which is about 16% at 10 or more years. This risk is noticeably elevated in patients under the age of 20 and collision athletes. Temporary postoperative stiffness can occur.

Recurrent Dislocation: About 16% at 10+ years (31% for any recurrent instability).
Post-operative Stiffness: Can occur after shoulder surgery and responds well to physical therapy.
Anchor Fixation Failure: Rare, but requires revision surgery.
Peripheral Nerve Damage (Axillary Nerve): Extremely rare and mostly temporary.
Infection: Less than 1% in arthroscopic cases.
Residual Pain: Responds to intra-articular injections in a small percentage of patients.

Complications of the Latarjet Procedure

Latarjet complications are more diverse than Bankart complications due to the technical complexity of the procedure. They include hardware/screw complications (0% to 16%), non-union of the bone graft (5% to 8%), and long-term osteoarthritis (8% to 42% at a 5-year follow-up). Notably, the recurrent dislocation rate itself is only 1% to 5%, which is the lowest among all stabilization techniques.

Screw Complications (Migration, Fracture, Irritation): 0% to 16%, occasionally requiring screw removal.
Coracoid Non-union: 5% to 8%, which can potentially impact long-term stability.
Degenerative Joint Osteoarthritis: Appears in 8% to 42% of cases at a 5-year follow-up according to systematic reviews.
Recurrent Dislocation: Only 1% to 5%—the lowest rate among all stabilization procedures.
Neurovascular Damage: Extremely rare and primarily associated with the surgeon’s learning curve.
External Rotation Stiffness: A mild loss of external rotation in some patients.

Differences Between Bankart and Latarjet Complications

Complication	Arthroscopic Bankart	Latarjet
Recurrent Dislocation (5 Years)	About 16% at 10+ years	1% – 5%
Post-operative Stiffness	10%	Less common
Hardware/Device Complications	Rare (Suture Anchors)	0% – 16% (Screws)
Long-term Joint Osteoarthritis	Lower	8% – 42% at 5 years
Bone Non-union	Not Applicable	5% – 8%
Nerve Injury Risk	Rare	Rare, but relatively higher

Factors That Increase the Risk of Complications

Five documented factors elevate the risk of complications after shoulder stabilization: an age under 20, participation in collision sports, choosing an inappropriate procedure for the degree of bone loss, the surgeon’s experience specifically with the Latarjet technique, and a premature return to collision activities before the surgeon’s 4-month evaluation.

An age under 20 at the time of surgery is statistically linked to a high recurrence rate after a Bankart repair. This demographic is highly prevalent in Egypt among football players, wrestlers, and martial artists. A key error to avoid is performing a Bankart repair on a patient who needs a Latarjet because of significant bone loss. This clinical mismatch sharply drives up recurrence and exposes the patient to a far more complex revision surgery. Bone loss is best measured with 3D CT, as MRI can underestimate it. Instead, a high-resolution 3D CT scan is mandatory for accurate surgical planning. A surgeon who does not routinely order a CT scan before deciding between a Bankart or a Latarjet may misclassify the pathology.

Complications of Shoulder Dislocation Surgery

When Do Symptoms Indicate a Post-Operative Complication?

Patients must contact their surgeon immediately if any of the following warning signs develop:

Redness, warmth, or drainage from the incision: Indicates a potential infection requiring immediate evaluation.
A fever exceeding 38.5°C after the third post-operative day: Warrants emergency laboratory blood tests.
Persistent numbness or weakness in the fingers or hand: Demands an immediate neurological assessment.
Sudden, severe pain unrelated to physical therapy exercises: Necessary to rule out an intra-articular issue or screw fracture.
A sensation of shoulder instability after the sixth week: Requires urgent radiological evaluation.

How to Prevent Complications After Shoulder Dislocation Surgery

Preventing complications begins pre-operatively with an accurate diagnosis of bone stock to choose the appropriate procedure, and continues post-operatively through absolute compliance with physical therapy and avoiding contact sports until cleared at the 4-to-5-month surgical evaluation.

Obtain a pre-operative 3D CT scan to quantify bone loss precisely.
Choose a Latarjet procedure over a Bankart repair if glenoid bone loss exceeds 20%.
Ensure the surgeon has performed an adequate volume of Latarjet procedures, as the learning curve directly impacts safety.
Begin structured physical therapy on the first or second post-operative day rather than waiting a week.
Do not return to contact or collision sports prior to a direct 4-to-5-month clinical evaluation by your surgeon.

Shoulder Stabilization Complications FAQ

Clinical statistics, comparative risks, and preventative guidelines regarding complications after shoulder dislocation surgery.

General surgical risks common to all shoulder operations, such as infection, severe bleeding, and joint stiffness, are exceptionally low, occurring in less than 1% of cases per complication. However, total complication rates vary noticeably depending on the technique chosen:

Arthroscopic Bankart Repair: Carries a total specialized complication rate of under 5%.
Open Latarjet Procedure: Carries a higher complication rate ranging from about 30% (mostly minor), reflecting its structural complexity.

American Knee & Shoulder Center Data

The failure or re-dislocation rate after a Bankart repair changes dramatically depending on follow-up duration and candidate selection:

Short-term (<5 years): Maintains a low recurrence rate of 6.7% in carefully selected patients who lack critical bone stock loss.
Long-term (10+ years): Recurrence rates rise significantly up to 20.9% over a mean 13.8-year follow-up. This long-term failure is heavily linked to patients with unrecognized bone loss who should have originally received a Latarjet procedure.

Because the Latarjet technique involves shifting bone and hardware fixation, its complication profile is highly unique:

Hardware/Screw Complications: Loosening, screw fracturing, or local tissue irritation occurs in 0% to 16% of cases, sometimes requiring secondary hardware removal.
Coracoid Non-union: The transferred bone graft fails to fuse with the scapular glenoid rim in 5% to 8% of patients, which can compromise long-term joint stability.
Degenerative Osteoarthritis: Long-term follow-ups show radiographic signs of arthritis in 8% to 42% of patients at 5 years, largely initiated by the trauma of original dislocations.

Source: Open Latarjet Systematic Reviews

The Latarjet procedure provides the highest structural stability, limiting recurrent dislocations to just 1% to 5%—the lowest recurrence rate among all stabilization choices.

By contrast, an arthroscopic Bankart repair exhibits a higher overall failure and re-dislocation profile, stretching from about 16% at 10+ years depending on the time elapsed from surgery and pre-existing patient anatomy.

American Knee & Shoulder Center Data

An age under 20 years old at the time of surgery is the single strongest statistically documented risk factor for a recurrent dislocation following an arthroscopic Bankart repair.

This high-risk demographic represents a massive clinical subset among young competitive collision athletes (such as football players, wrestlers, and mixed martial artists) who frequently exhibit high soft-tissue elasticity and substantial re-injury forces.

Source: Clinical Failure Timeline Studies

The most frequent error in modern surgical planning is executing a soft-tissue Bankart repair on a joint that possesses glenoid bone loss exceeding 20%. This structural mismatch sharply drives up recurrence rates and exposes the patient to a highly complex revision surgery later.

Crucial Fact: Relying solely on an MRI can lead to this error, because standard MRI scans underestimate the true volume of bone loss in some cases. A high-resolution 3D CT scan is mandatory before the operation to avoid misclassification.

Source: International Shoulder Surgical Literature

In roughly 10% of shoulder operations, temporary joint stiffness and restricted mobility are observed during the early post-operative weeks. This is a normal physiological healing trait that typically resolves entirely within 3 months of a structured physical therapy protocol.

For the Latarjet procedure specifically, patients should expect a minor, permanent mild loss of external rotation compared to pre-injury levels, which is a known trade-off for the procedure’s high stability.

Source: Post-Operative Mobility Statistics

No, peripheral nerve injuries (most commonly impacting the axillary nerve) are extremely rare. In the vast majority of cases, any neurovascular symptoms are completely transient and stem from temporary tissue traction or stretching during surgical maneuvers rather than structural nerve transection.

Because the deep neurovascular pathways of the shoulder are highly intricate, avoiding this complication is directly related to the surgeon’s specialized learning curve and volume of operations.

Patients must closely monitor their recovery and contact their surgical team immediately if any of the following warning signs manifest:

Redness, localized warmth, or fluid drainage: Suggests an acute wound infection that requires immediate diagnostic assessment.
A fever exceeding 38.5°C after day 3: Demands emergency laboratory blood profiles.
Persistent numbness or sudden weakness in the hand/fingers: Warrants immediate neurological screening.
Sudden, sharp pain at rest: Requires evaluation to rule out an intra-articular tissue failure or screw fracture.
A sensation of instability or catching after week 6: Demands urgent radiological re-evaluation.

Emergency Protocol Guidelines

Minimizing surgical risks is achieved through five specific clinical actions:

Insist on a high-resolution 3D CT scan prior to surgical planning to map out exact bone stock.
Opt for a Latarjet procedure over a Bankart repair if glenoid bone loss is quantified at 20% or more.
Verify that your orthopaedic surgeon routinely performs a high annual volume of Latarjet stabilizer surgeries.
Begin structured, specialized physical therapy exercises on post-operative day 1 or 2 rather than delaying rehabilitation.
Strictly avoid all contact sports or heavy lifting until undergoing a direct, formal clinical evaluation by your surgeon at the 4-to-5-month mark.
