Bankart Repair
What Is a Bankart Lesion?
The shoulder’s humeral head moves against the shallow glenoid socket. A fibrocartilage rim called the labrum deepens that socket, and the capsule and ligaments help keep the joint centred. A Bankart lesion occurs when the anteroinferior labrum and attached capsule separate from the front-lower glenoid, usually during an anterior dislocation. The injury can weaken the bumper and tension that resist the humeral head moving forward, contributing to anterior instability. A Bankart lesion is therefore a structural finding, while instability describes the patient’s symptoms and abnormal joint movement. The shoulder overview explains how the labrum, capsule, rotator cuff and bony surfaces work together.
Symptoms and Anterior Shoulder Instability
A first shoulder dislocation is usually painful and may leave the joint deformed until it is reduced. After reduction, a patient may have pain, weakness, clicking or a sense that the shoulder will slip when the arm moves away from the body and rotates outward. Subluxations may slide partly out and back without the obvious deformity of a complete dislocation. Repeated episodes, avoidance of overhead positions and apprehension during sport or daily tasks suggest symptomatic instability rather than an imaging finding alone. Recurrent shoulder dislocation requires assessment of why stability has not returned. New numbness, weakness or a cool hand needs urgent neurovascular review.
Bone Loss, Bony Bankart and Hill-Sachs Lesions
Dislocation can injure bone as well as the labrum. A bony Bankart includes a fragment or deficiency of the front-lower glenoid rim. A Hill-Sachs lesion is a compression dent in the back of the humeral head created as it strikes the socket edge. Clinicians assess these lesions together. The “glenoid track” concept asks whether the humeral-head dent remains supported by the available socket during vulnerable movement. An on-track lesion is less likely to catch the rim, whereas an off-track lesion may engage and lever the head forward. This relationship, glenoid bone loss, fragment quality, laxity, activity and previous operations guide planning; no universal percentage or single measurement chooses the operation for every patient.
Who May Be Considered for Bankart Repair?
Repair is commonly discussed for recurrent, symptomatic anterior instability when the capsulolabral lesion is repairable and bone loss does not make soft-tissue repair alone unreliable. It may also be considered after a selected first dislocation when structural damage, sport or occupation, age, recurrence risk and personal priorities support earlier stabilization. Surgery is not automatic after either a first event or an MRI-detected tear. Non-operative care may include a period of protection after reduction, pain control and progressive rehabilitation for motion, rotator-cuff strength, shoulder-blade control and confidence. The decision compares the burden of continued episodes with surgical risk, expected activity and the possibility that another procedure better addresses the anatomy.
Examination and Instability Testing
The history records how the injury occurred, the direction and number of episodes, whether reduction was required, sport or work demands, previous treatment and any numbness or weakness. Examination looks for deformity, tenderness, range of motion, rotator-cuff and shoulder-blade strength, generalized laxity and signs of other labral or tendon injury. Apprehension testing places the arm toward a position that previously felt unstable; relief when the examiner supports the humeral head can reinforce an anterior instability pattern. Testing is cautious and is not used to force a dislocation. Pulses, hand perfusion, sensation and motor function are checked, particularly after an acute event, because nerves and vessels can be injured.
X-Ray, MRI and CT Planning
X-rays confirm that the shoulder is located and may show a glenoid-rim fracture, Hill-Sachs lesion or other bone injury. MRI evaluates the labrum, capsule, cartilage, rotator cuff and associated soft tissues; an MR arthrogram may be selected when more detail around the labrum and capsule is needed. CT, often with three-dimensional reconstruction, is useful when the amount and shape of glenoid or humeral-head bone loss could change the operation. Not every patient needs every scan, and measurements can vary by technique. Imaging must be interpreted alongside symptoms, examination, episode history and activity because a visible Bankart lesion does not by itself prove that surgery is required.
How Is Arthroscopic Bankart Repair Performed?
Arthroscopic stabilization uses a camera and instruments passed through small portals to inspect the joint and confirm the instability pattern. The detached labrum and capsule are mobilized, the glenoid edge is prepared for healing, and sutures attached to anchors secure the tissue back to the rim. Capsular shift or plication can reduce excess capsular volume and restore tension when indicated. Anchor number, position and material depend on lesion extent, tissue and bone quality rather than a fixed formula. The arthroscopic stabilization overview places Bankart repair within the wider instability pathway, while failed shoulder stabilization requires renewed analysis of tissue and bone loss. A selected open Bankart repair may suit particular circumstances, but it remains a capsulolabral repair performed through an incision; it is not by definition a tendon graft or bone block.
Remplissage, Latarjet and Bone-Block Options
Remplissage and Latarjet are not alternative names for Bankart repair. Remplissage is an adjunct that fixes the posterior capsule and part of the infraspinatus into a relevant Hill-Sachs defect so it is less likely to engage the glenoid rim; it may affect rotation and is selected according to the combined bone pattern and activity. Latarjet transfers the coracoid bone with attached tendon to reinforce the front of the glenoid, while other bone-block procedures use different grafts. These options may be considered for substantial glenoid loss, an off-track lesion, failed soft-tissue stabilization or other high-risk anatomy. The Latarjet procedure has distinct benefits and complications and should not be added automatically to every Bankart lesion. The shoulder arthroscopy page explains the keyhole access used for arthroscopic repair and selected adjuncts.
Anaesthesia and the Day of Surgery
Before surgery, the team reviews imaging, medications, allergies, general health and the planned repair or possible adjunct. Bankart repair is commonly performed under general anaesthesia, sometimes with a regional nerve block for pain control when appropriate. The patient is positioned so the surgeon can examine stability and access the shoulder safely. After repair, portal or open incisions are closed and the arm is placed in a sling. Discharge planning depends on anaesthetic recovery, pain control, medical needs and support at home. Instructions should specify wound care, permitted hand and elbow movement, shoulder restrictions, medication use and who to contact if symptoms change.
Sling Protection and Staged Rehabilitation
A sling protects the healing capsulolabral repair during the early phase, but duration and permitted removal vary with the procedure and patient. Rehabilitation balances protection against excessive stiffness. It typically progresses from hand, wrist and elbow movement and protected shoulder motion to active control, range restoration, rotator-cuff and shoulder-blade strengthening, endurance and task-specific loading. External rotation, abduction, lifting and sudden reaching are advanced according to tissue healing and the operative plan rather than a generic calendar. Pain, swelling, wound condition, movement quality and apprehension guide progression. A patient whose instability procedure included remplissage, bone transfer or revision may follow different restrictions from an isolated Bankart repair.
Return to Work and Sport
Return is criteria-based as well as time-aware. Useful markers include a healed repair, functional and near-symmetrical range for the intended task, adequate strength and endurance, controlled shoulder-blade mechanics, absence of instability or apprehension, and completion of progressive work or sport drills. Contact, collision and overhead activities place different demands on the repair, and psychological confidence also matters. Outcomes vary with age, glenoid and humeral bone loss, tissue quality, generalized laxity, contact-sport exposure, previous surgery and adherence to rehabilitation. Recurrent symptoms require a fresh assessment rather than an assumption that repeating the same repair will succeed.
Risks, Alternatives and Warning Signs
Risks include recurrent subluxation or dislocation, stiffness, persistent pain, infection, bleeding, nerve or blood-vessel injury, anchor irritation or failure, cartilage damage, wound problems, anaesthetic complications and deep-vein thrombosis. Further surgery may be needed if instability recurs or unrecognized bone loss remains important. Alternatives include rehabilitation, activity modification, selected open soft-tissue repair, remplissage, Latarjet or another bone-graft reconstruction according to the pathology. Capsulolabral reconstruction is a separate selected option when native soft tissue is insufficient, not a routine Bankart repair. Seek prompt advice for fever, drainage, worsening redness or pain, a cold or discoloured hand, new numbness or weakness, loss of finger movement, breathing difficulty or another dislocation. Do not attempt to reduce a dislocated shoulder yourself.
