Anyone who has felt a shoulder slip forward once carries a quiet fear that it will happen again, in the exact same position, at the exact same angle. Follow-up studies on young, active patients consistently show a high rate of repeat instability after a first traumatic anterior dislocation, and once imaging confirms a Bankart lesion — a tear of the labrum, the ring of cartilage that lines the socket — early arthroscopic repair is usually recommended over waiting it out.
The surgery itself is a well-established procedure. What actually determines whether the shoulder stays put, though, is not decided in the operating room. It is decided over the following several months of rehabilitation. Push the repaired tissue before it has had time to biologically knit back together and the risk is a re-tear. Go too cautiously the other way and the result is a stiff, weak joint that feels unstable for entirely different reasons. The quality of the outcome depends less on surgical technique than on how consistently the patient follows the phase-by-phase rules that come after.
This article walks through what a Bankart repair actually corrects, how the capsule and repaired tissue heal in real time, and a four-phase rehabilitation protocol laid out week by week, from the initial protection period through return to sport. It also covers where near-infrared (NIR) LED light can reasonably fit into that routine as a wellness aid, and where it cannot. An NIR device is not a medical treatment for pain or disease. It is best understood as a supporting tool for circulation and conditioning around the joint, nothing more.
Understanding the Bankart Lesion and Repair
Understanding the Bankart Lesion and Repair
A Bankart lesion happens when the humeral head shifts forward during a dislocation and tears the anteroinferior labrum away from the glenoid rim. The labrum is the ring of cartilage that deepens the shallow glenoid socket and helps keep the humeral head centered. Once it detaches, the joint tends to keep sliding forward under the same stresses that caused the first injury. When a piece of bone comes away along with the labrum, surgeons call it a bony Bankart lesion, and once that bone loss exceeds roughly 20 to 25 percent of the glenoid width, a soft-tissue repair alone is usually not enough on its own — bone grafting or a Latarjet coracoid transfer procedure gets added to the conversation.
A prospective cohort study of US military cadets by Owens and colleagues (American Journal of Sports Medicine, 2009) followed young patients after a first traumatic anterior dislocation and found that a substantial share went on to develop recurrent instability, with the risk noticeably higher among contact-sport athletes and patients under about 20 years old. That evidence is a large part of why early arthroscopic repair has become the default recommendation for young, active patients rather than a trial of conservative treatment first.
How the Repair Works
An arthroscopic Bankart repair is done through two or three small portals at the front of the shoulder. Suture anchors go into the bone along the glenoid rim, and the sutures running from each anchor pull the detached labrum and the loose inferior capsule back against the bone where they belong. When the capsule itself has stretched out, surgeons often add a capsular plication, essentially taking a tuck in the tissue, to shrink the extra room inside the joint. The number of anchors used typically runs from three to five depending on how much labrum tore away, and several biomechanical studies have found that anchors placed closer together restore the labrum's convex ridge, the bumper effect that blocks the humeral head from sliding off the front of the socket, more reliably than anchors spaced further apart.
How the Repaired Tissue Actually Heals
Right after surgery, the tissue is held together mechanically by suture and by a weak, immature fibrous bond. It has essentially no biological strength of its own yet. Real reattachment between bone and soft tissue, the kind that can bear an actual tensile load, takes roughly six to twelve weeks to develop. For the first two to three weeks, the repair depends entirely on the hardware. Between weeks four and six, collagen fibers begin to reorganize and the bond slowly gains strength. It is usually not until eight to twelve weeks that the tissue can handle everyday loading. Pushing external rotation or abduction past the prescribed limits during this window can pull the healing edge back apart before it has had a chance to mature, which is exactly why the early range-of-motion restrictions are non-negotiable rather than a suggestion.
How Near-Infrared Light Fits Into the Healing Environment
A widely cited review of photobiomodulation by Huang and colleagues (Photomedicine and Laser Surgery, 2009) describes how red and near-infrared wavelengths in roughly the 600 to 900nm range are absorbed by cytochrome c oxidase inside mitochondria, which can increase ATP production and, across a number of cell and animal studies, appears to support local blood flow and oxygen delivery. What that means in practice for a post-surgical shoulder is worth being precise about: this is not a mechanism that heals the repair site itself. It is closer to supporting the circulation and conditioning of the surrounding soft tissue. The actual strength of the repair comes back through time, controlled loading, and rehabilitation exercise. Light is a supporting actor here, not the lead.
Why the Joint Can Still Feel Unstable Even After a Solid Repair
It helps to understand why instability can persist even when the anchors and sutures are doing their job structurally. The shoulder does not move as a single hinge. Raising the arm requires the scapula to rotate and tilt in coordination with the humerus, a relationship called scapulohumeral rhythm. If the muscles that control the scapula, particularly the serratus anterior and lower trapezius, stay weak or poorly coordinated during early rehab, the humeral head can ride slightly off-center in the socket every time the arm is raised, even though the labrum itself is anatomically repaired. Repeated over hundreds of reaching and lifting motions a day, that small malalignment loads the repair from an angle it was not really built to resist, which is one reason surgeons and physical therapists pay as much attention to scapular control drills in the first few weeks as they do to the raw number of degrees of motion regained. A skilled manual therapist can usually spot this compensatory pattern early, before it becomes a habit that is harder to unlearn later.
The 4-Phase Rehabilitation Protocol
The Four-Phase Rehabilitation Protocol After Bankart Repair
Rehabilitation after a Bankart repair works by gradually increasing the load placed on the repaired tissue in step with its biological healing timeline. A widely used framework for arthroscopic shoulder-instability rehab from Millett and colleagues (Sports Health, 2014) recommends organizing recovery into protection, mobility, strengthening, and return-to-activity phases that track the tissue's healing timeline rather than a fixed calendar. The table below adapts that framework into the week-by-week milestones commonly used in rehab clinics.
Why the Phases Are Kept Separate
Rushing the timeline loads the repair before it has the tensile strength to take it, which is how re-tears happen. Being overly cautious in the other direction causes stiffness and muscle wasting that slows functional recovery just as much. In practice, the decision to move from one phase to the next should weigh actual tissue-healing status and pain-free active range of motion together, not just the calendar date. A patient healing faster or slower than average is not unusual, and a good rehab team adjusts to that rather than following the chart mechanically.
| Phase | Timeframe | Motion Limits | Key Rehab Focus | NIR Use |
|---|---|---|---|---|
| 1. Protection | Weeks 0-3 | Abduction sling worn, active external rotation limited to 0 degrees | Pendulum exercises, active wrist and elbow motion, scapular stabilization | No direct irradiation until the incision is fully closed |
| 2. Mobility | Weeks 3-6 | External rotation progressed to 30 degrees, abduction to 90 degrees | Assisted active range-of-motion work, scapulothoracic rhythm training | Once the incision has healed, 8-10 minutes around the shoulder, once daily |
| 3. Strengthening | Weeks 6-12 | Most active motion in all directions restored | Resistance-band work for the rotator cuff and scapular stabilizers, closed-chain exercise | Warm-up and recovery support around training sessions, 4-5x per week, 10-15 minutes |
| 4. Return to Activity | Weeks 12 to 6 months | No formal restriction; the abduction-plus-external-rotation position is monitored closely | Plyometrics, sport-specific movement, controlled exposure to the position that caused the original injury | Post-training conditioning use, 3-5x per week |
Progression Criteria and Stop Signs, Phase by Phase
Moving from protection to mobility around week three generally requires a healed incision, no signs of infection, and passive motion that does not provoke sharp pain at the anchor site. Moving from mobility into strengthening around week six usually requires roughly 80 percent of pain-free active range compared with the uninjured side, along with confidence performing daily tasks like reaching for a seatbelt without guarding the arm. Moving into the return-to-activity phase after week twelve typically requires rotator-cuff strength in the 70 to 80 percent range compared with the other side and a negative apprehension test. At every stage, a sharp increase in pain, a new clicking or catching sensation, or a feeling that the joint is about to slip are all reasons to pause and have the surgical team re-examine the shoulder rather than pushing through on the assumption that discomfort is just part of the process.
What to Watch for With Home Rehab
The decision to move to the next phase should come from tissue-healing status and active range of motion as assessed by the surgeon and rehab therapist, not from how good the shoulder happens to feel that day. When using NIR LED alongside rehab exercise, check the incision for any sign of infection or an open wound before every session, and aim the light broadly across the deltoid and rotator-cuff area rather than directly over the anchor sites in the joint itself. Related mobility programming is covered in the aquatic rehabilitation guide, since pool-based exercise uses buoyancy to reduce joint loading while still building range of motion.
What Strengthening-Phase Training Actually Looks Like
Once the strengthening phase starts, resistance-band internal and external rotation, wall push-up-plus work for the serratus anterior, and rowing-pattern exercises that draw the shoulder blades back form the core of the program. Repetitions should climb gradually within a pain-free range, and if the shoulder starts clicking or gives a deep, unstable ache, the right response is to drop the intensity immediately and re-check it at the next session rather than pushing through. The return-to-activity phase layers on short, quick-impact plyometric drills and movement patterns that mimic the actual sport, so the joint gets tested under conditions closer to real competition before it is asked to perform under it. If pain or a feeling of instability reappears at any point in this phase, the same rule applies: back off and check in with the surgical team rather than assuming it will work itself out.
Recurrence Rates and Recovery Milestones
Recurrence Rates and Recovery Milestones After Bankart Repair
A systematic review and meta-analysis by Kavaja and colleagues (British Journal of Sports Medicine, 2018) pooled data from multiple randomized and cohort studies and found that patients who had early arthroscopic Bankart repair had a significantly lower risk of recurrent instability than those managed conservatively. The same review noted that risk does not drop to zero. Patients with substantial bone loss, or those who return to contact sport early, keep a meaningfully higher recurrence risk even after a technically sound repair. The factors that come up again and again as protective are adequate rehab time, holding off on early return to contact sport, and restoring side-to-side strength balance around the shoulder.
Recovery Milestones Tracked Phase by Phase
- Range of motion: reaching roughly 80 percent of the uninjured side's abduction by around week six is a common interim target.
- Strength: isometric rotator-cuff strength reaching 70 to 80 percent of the uninjured side by around week twelve.
- Apprehension: the point at which the abduction-external-rotation position stops producing fear or pain is treated as an important marker for clearing return to activity.
- Functional scores: standardized questionnaires such as the Rowe score and the WOSI, the Western Ontario Shoulder Instability Index, track subjective recovery over time.
- Scapular rhythm: watching whether the scapula and humerus move together smoothly during arm elevation helps flag compensatory movement patterns.
Why Strength Training During Recovery Matters for Preventing Recurrence
Even when the labrum repair restores structural stability on its own, weak rotator-cuff and scapular muscles can leave a dynamic instability behind: the humeral head drifting slightly off-center in the socket every time the arm moves, even though nothing is structurally torn. That is part of why the strengthening phase focuses heavily on the infraspinatus, teres minor, and serratus anterior, the muscle group that holds the shoulder down and back. Returning to sport with a lingering side-to-side strength imbalance lets small, off-axis loads accumulate over thousands of repetitive motions even when the repair itself looks stable on imaging, which is part of why checking strength symmetry carefully has become such a standard part of clearing an athlete for return.
Where NIR LED use fits into this picture as a wellness aid, there is no basis for claiming it independently improves any of the clinical markers above. It is best approached as a supporting tool for muscle relaxation and local circulation before and after rehab sessions. The actual recovery is driven by phase-appropriate strengthening and mobility work.
Precautions to Prevent Redislocation

Common Mistakes Right After Surgery
The mistakes that show up most often in rehab clinics are stopping the sling early because the pain has faded, or pushing the arm overhead before the prescribed motion limits allow it. Repaired tissue can feel perfectly comfortable while still well short of the strength it needs. Progression should be based on time since surgery and the surgeon's exam findings, not on how little the shoulder hurts. Mistaking the absence of pain for the tissue being fully healed is, more than anything else, the first step toward a re-tear.
- For the first three weeks, wear the prescribed sling even while sleeping, and do not actively raise the arm overhead without the surgeon's clearance. The fix for feeling ready early is to check with the surgical team, not to test it yourself.
- Avoid any position that combines maximum abduction and external rotation at once, such as the throwing cocking position or catching yourself with an arm thrown back overhead, for at least 12 weeks, since this loads the repair more than almost any other movement.
- Hold off on contact sport or activities with a real fall risk until strength, range of motion, and apprehension testing have all cleared, and set the actual return date together with the surgical team rather than by feel.
- Everyday moments that quietly load the shoulder into abduction and external rotation, such as reaching back while driving, lifting a heavy bag overhead into a car, or grabbing an overhead strap on a crowded train, deserve the same conscious avoidance early on as formal exercise does.
- Sleeping on the operated side, or letting the arm drift overhead during sleep, is an easy way to load the repair without noticing. A wedge pillow, or simply sleeping on the back with the sling on for the first few weeks, avoids this.
- If NIR irradiation causes redness, drainage, or any separation at the incision, stop using it and have the surgeon check the site.
- Avoid direct eye exposure, and check with the prescribing physician first if taking any photosensitizing medication.
- NIR LED is a supporting tool, not a substitute for rehab exercise. If pain or instability persists or gets worse, see a specialist rather than relying on light therapy to manage it.
Warning Signs That Need a Doctor, Not More Rest
A few signs go beyond normal post-surgical soreness and are worth calling the surgical team about the same day rather than waiting for the next scheduled visit: pain that wakes you up at night and is not relieved by repositioning the arm, fever or spreading redness and warmth around the incision, unexplained weight loss, or new numbness, tingling, or weakness running down the arm into the hand. Any of these can point to an infection, a nerve issue, or a complication that needs to be looked at directly rather than managed at home with rest and light therapy.
The real goal after a Bankart repair is not simply being pain-free. It is being able to move through the same range used before, confidently, without wondering if the shoulder is about to give out. Following the phase-by-phase rehab principles carefully, with NIR wellness support layered on top rather than relied on as the main plan, is what gets most patients back to their previous activity level safely.
Long-Term Shoulder Care
The shoulder does not stop needing attention once formal rehab ends. Keeping up rotator-cuff and scapular stabilization work two to three times a week after returning to full activity helps keep recurrence risk down, and it is worth paying attention to posture during long stretches at a desk, since a habitually rounded, forward shoulder position undoes some of what the strengthening phase built. If the shoulder feels achy with a change in season or when overall conditioning dips, easing off intense activity and leaning on gentle stretching and wellness-level NIR support for a few days is a reasonable response. If the same ache keeps coming back or lingers, that is a signal to get reassessed rather than to keep managing it alone.
