Capsular contracture is the most common long-term complication of breast augmentation with implants — but it is important to keep it in perspective: only around 1–2% of breast augmentation patients ever require treatment for it. It occurs when the natural scar tissue capsule that forms around a breast implant thickens and tightens, squeezing the implant and causing the breast to feel firm, look distorted, or become painful. This guide explains what causes capsular contracture, the Baker grades, how it is diagnosed, and the full range of surgical and non-surgical treatments — as well as how to avoid capsular contracture developing in the first place.
Capsular contracture is highly treatable, and concern about it should not deter anyone from breast surgery: for the vast majority of patients the benefits far outweigh this small risk. At Centre for Surgery in London, our GMC-registered plastic surgeons both minimise the risk through careful technique and treat established capsular contracture with implant removal, replacement, and capsulectomy at our CQC-regulated Baker Street clinic, under TIVA (Total Intravenous Anaesthesia) as a day case.
What Is Capsular Contracture?
When any foreign object, such as a breast implant, is placed in the body, the immune system responds by forming a protective barrier of scar tissue around it. This barrier — the fibrous capsule — is a normal and expected part of healing, and it actually helps to hold the implant in place. In most people the capsule stays thin, soft, and unnoticeable.
In capsular contracture, this immune response becomes exaggerated. The capsule thickens and contracts around the implant, and the breast can begin to feel hard, look distorted, and become painful. In severe cases the breast can appear visibly misshapen and unnaturally round. The severity varies from person to person and depends on factors including the implant used, the surgical technique, and the individual’s healing response. It can develop within the first 6–12 months after surgery, or, less commonly, years later — including breast implant hardening after 10 years or more, which is why long-term monitoring matters even for patients who’ve had trouble-free implants for a decade or longer.
To describe severity objectively, surgeons use the Baker classification, ranging from Grade I (soft, natural breasts) to Grade IV (hard, painful, distorted breasts) — explained in full below. Treatment depends on the grade, ranging from monitoring in mild cases to surgery in more severe ones.
What Causes Capsular Contracture?
The exact cause of capsular contracture is still not completely understood, but research points to a few leading explanations, and it is generally considered a multifactorial condition.
The bacterial biofilm theory is the leading explanation for what causes capsular contracture. It proposes that a thin layer of bacteria (most commonly Staphylococcus species from the skin) forms on the implant surface during surgery, triggering a low-grade, chronic inflammatory response that thickens the capsule over time. This is why surgeons take great care with sterile technique, antibiotic irrigation of the implant pocket, and minimal-touch implant insertion — all aimed at reducing bacterial contamination. Our own analysis of texture as a risk factor specifically — including data from our own patients — is covered in detail in our guide on whether textured or smooth implants affect capsular contracture risk.
A related exaggerated immune and inflammatory response — sometimes following a haematoma (blood collection) or seroma (fluid collection) around the implant — can also drive excessive capsule formation. Beyond these, the type of implant, the surgical technique, and individual biology and genetics all play a part.
Understanding the Risk Factors for Capsular Contracture
Several factors influence the risk of developing capsular contracture, and understanding them helps both in prevention and in making informed choices before surgery.
Reason for Surgery: Primary vs Revision
The risk is lower in first-time (primary) breast augmentation than in breast implant revision or breast reconstruction after mastectomy, where the risk is higher.
Surgical Technique and Implant Placement
The implant can be placed under the chest muscle (submuscular) or above the muscle beneath the breast tissue (subglandular). Submuscular placement carries a lower risk of capsular contracture. A systematic review of 40 studies by Bachour and colleagues identified subglandular placement, postoperative haematoma, a textured implant surface, longer follow-up and reconstruction after breast cancer as the factors most consistently associated with increased risk, while finding little or no reliable evidence for many others (DOI ↗). Sterile technique and antibiotic irrigation of the surgical pocket further reduce risk by limiting bacterial contamination. Our guide on implant placement over or under the muscle explains the difference.
Time Since Surgery
Capsular contracture is progressive — the longer implants have been in place, the higher the cumulative likelihood. It’s a genuine misconception that trouble-free implants at the 5 or 10-year mark mean the risk has passed entirely; regular monitoring of your implants for the long term, not just in the first year or two, helps with early detection.
Implant Brand and Quality
Choosing a reputable, high-quality implant brand matters. At Centre for Surgery we use Silimed implants as our exclusive implant brand, chosen for their quality and safety profile. Your surgeon will discuss implant choice fully during your consultation.
Implant Filling: Silicone vs Saline
Implants are filled with silicone or saline. Silicone gives a more natural look and feel; saline is easier to place and adjust. The data on which carries a higher capsular contracture risk is debated and not conclusive. Our comparison of silicone vs saline implants covers this in detail.
Implant Shell Surface: Textured vs Smooth
Textured implants were historically associated with a lower contracture risk and better position stability. However, textured implants have been linked to a rare condition, Breast Implant-Associated Anaplastic Large Cell Lymphoma (BIA-ALCL), so this must be weighed carefully. Our own review of Centre for Surgery patient outcomes between 2016 and 2022 found no statistically significant difference in capsular contracture rates between smooth and textured implants — surgical technique appeared to matter more than texture itself. The full findings, and why we’ve moved to smooth and microtextured implants as standard regardless, are covered in our dedicated guide: Textured vs Smooth Breast Implants: Does Texture Affect Complication Risk?
Breast Cancer Treatment
The risk is higher in patients who have had chemotherapy or, particularly, radiotherapy, which increases inflammation and fibrosis around the implant.
Symptoms of Capsular Contracture
Symptoms usually progress gradually over time and increase in severity. In the early stages they can be subtle and barely noticeable, becoming more apparent as the condition develops. The main signs to be aware of are:
- Firmness and hardening: As the capsule thickens and tightens, the breast feels progressively firmer and harder — often the first noticeable sign.
- Altered breast shape: The affected breast may shrink, become more spherical or rounded, and take on an unnatural, uneven contour.
- Pain and discomfort: A tight capsule can cause pain, ranging from mild discomfort to significant pain in more advanced cases.
- Implant displacement: The implant may feel as though it has shifted position, often riding higher on the chest or towards the armpit.
Capsular contracture can affect one or both breasts, and symptoms may differ between them. If you notice any of these changes, it is important to see a breast surgeon promptly — earlier assessment gives more treatment options.
Diagnosing Capsular Contracture
If you suspect capsular contracture, a consultation with a breast surgeon is the first step. Your surgeon will ask about your symptoms, implant type, and original surgery, then perform a physical examination assessing firmness, deformity, and tenderness. To confirm the diagnosis and rule out other causes, one or more imaging tests may be used.
MRI Scanning
MRI is the gold standard for assessing breast implants and capsular contracture, offering high-resolution images of the implant and surrounding tissue.
Mammography
Useful for detecting mild to moderate cases, though of limited value in severe cases, and less suitable for younger patients.
Ultrasound
A high-resolution ultrasound scan can detect capsular contracture, though its accuracy depends heavily on the experience of the person performing it.
The Baker Classification System
Surgeons use the Baker classification to grade severity, which guides treatment:
- Baker I: The breast looks and feels natural and soft. The capsule is not contracted.
- Baker II: Minimal contracture — the breast is slightly firm but looks normal.
- Baker III: Moderate contracture — the breast feels abnormally firm and shows some visible distortion.
- Baker IV: Severe contracture — the breast is hard, visibly distorted, and painful.
Baker I and II generally require no treatment and are simply monitored. Baker III and IV are more severe and usually warrant intervention to relieve symptoms and restore the breast’s appearance.
Surgical Treatments for Capsular Contracture
Capsulotomy
In an open capsulotomy, the surgeon cuts the tight fibrous bands of the capsule to release tension and restore a softer, more natural shape, without fully removing the capsule. It is less extensive than capsulectomy and is often preferred for submuscular implants.
Capsulectomy
Capsulectomy involves complete removal of the fibrous capsule along with the implant. Though more invasive, it ensures all scar tissue and any contaminants are removed, reducing the chance of further contracture. Our guides on en bloc capsulectomy and en bloc vs partial capsulectomy explain the options.
Implant Replacement
Repositioning or replacing the implant — sometimes creating a fresh “neo-pocket” in a different plane — can improve outcomes and reduce recurrence when combined with capsulotomy or capsulectomy.
Autologous Fat Transfer
Autologous fat transfer — harvesting your own fat via liposuction and injecting it into the breasts — is being explored as a treatment, thought to improve circulation around the capsule and soften the breast. It may be combined with capsulectomy or used as part of reconstruction after implant removal.
Implant Removal
In severe or recurrent cases, complete breast implant removal may be recommended. This usually resolves the problem, though the cosmetic result can require a breast uplift (mastopexy), skin removal, or fat transfer to restore shape.
Risk of Recurrence After Revision Surgery
It is important to be aware that capsular contracture can recur after revision surgery, and the risk is meaningfully higher than after the original operation — studies suggest roughly one in four women may experience recurrence within a year of a corrective procedure, and repeated revisions carry a rising risk each time. Newer techniques, such as the neo-pocket method and the use of acellular dermal matrix, are being studied to reduce this recurrence risk. Part of the difficulty is that the underlying cause is still not settled. A review in Aesthetic Plastic Surgery concluded that the exact cause of capsular contracture remains unclear, and that it is most likely multifactorial — with immunological factors and bacterial contamination around the implant both implicated (DOI ↗). That uncertainty is worth knowing about, because it is the reason no single preventive measure can be promised to work.
How Much Does Capsular Contracture Treatment Cost?
The cost depends on the procedure required — capsulotomy, capsulectomy, implant removal, or removal and replacement — and its complexity. Every case is individual, so an accurate price is confirmed in writing after your consultation. Finance options are available through our partner Chrysalis Finance for procedures over £1,500 — visit our Finance Options page for details.
Will the NHS Cover Capsular Contracture Surgery?
The NHS does not generally fund capsular contracture treatment as standard, since breast augmentation itself is a cosmetic procedure. However, capsular contracture surgery on the NHS may be considered where it is causing significant pain, complications, or a substantial impact on quality of life. Each case is assessed individually, and eligibility varies by local Integrated Care Board. Discuss your situation with your GP, who can advise whether your case may qualify for NHS-funded treatment. NHS policies change over time, so always confirm current criteria with your healthcare provider.
How to Avoid Capsular Contracture
While not every case is preventable, informed choices before surgery and good care afterwards meaningfully reduce the risk of capsular contracture developing.
Choose a Skilled, Experienced Surgeon
An experienced surgeon using strict sterile technique, antibiotic pocket irrigation, and appropriate implant placement reduces the risk of contamination and contracture — and provides the follow-up care that catches any issues early.
Select a High-Quality Implant
A reputable implant brand — Silimed at Centre for Surgery — and the right implant type for your anatomy help minimise risk. Discuss the options fully with your surgeon.
Omega-3 Supplements
Omega-3 and fish oil supplements are sometimes suggested on the basis that they may support healing and contribute to a less rigid capsule. It is worth being straightforward about the evidence here: we are not aware of good-quality trial data in humans showing that supplements reduce the risk of capsular contracture, and the systematic review cited above found little or no reliable evidence for most proposed risk and protective factors beyond the few it identified. Treat this as unproven rather than established, and always consult your surgeon before starting any supplement after surgery.
Regular Breast Massage
Daily breast massage in the first few months after surgery is commonly recommended on the basis that it may help keep the capsule soft and thin. As with supplements, the evidence for this is weaker than the frequency of the advice suggests, and practice varies between surgeons — some recommend it routinely, others do not recommend it at all, and it is not advised with every implant type or placement. Follow your own surgeon’s guidance on whether to massage, and on technique and frequency, rather than generic instructions found online.
Frequently Asked Questions about Capsular Contracture
How common is capsular contracture?
It is the most common long-term complication of breast implants, but only around 1–2% of breast augmentation patients require treatment for it. For most people, breast surgery proceeds without ever developing it. Published rates vary considerably depending on the patient group studied. A Mayo Clinic review of 451 mastectomy patients with implant reconstruction reported an overall incidence of 9.8%, rising to 18.7% in those who had radiotherapy after mastectomy and falling to 7.5% in those who did not (DOI ↗). A Swedish national registry study of 1,095 reconstructions after risk-reducing mastectomy found severe contracture requiring surgery in 3.6%, with the cumulative rate climbing from 1.9% at one year to 4.7% at five (DOI ↗). Reconstruction figures run higher than cosmetic augmentation, so these are not the numbers to apply to a straightforward breast augmentation.
Can capsular contracture develop suddenly?
It usually develops gradually, with mild symptoms that progress over time. It is unlikely to appear overnight, but any sudden change in the appearance or feel of your breasts should be assessed by your surgeon.
Can capsular contracture develop after 10 years or more?
Yes. While most cases develop within the first 6–12 months, capsular contracture — and breast implant hardening more generally — can also appear years later, including after a decade or more of trouble-free implants. This is why ongoing monitoring matters throughout the life of your implants, not just in the early recovery period.
Can capsular contracture resolve on its own?
It typically does not resolve by itself. Mild cases (Baker I and II) may simply be monitored, but more severe cases (Baker III and IV) usually need surgical or non-surgical intervention.
Can weightlifting cause capsular contracture?
There is no direct evidence linking weightlifting to capsular contracture, though excessive strain on the chest muscles soon after surgery is best avoided. Follow your surgeon’s post-operative guidance on returning to exercise.
Is capsular contracture dangerous?
It is not life-threatening, but it can cause discomfort, pain, and breast deformity, and untreated severe cases may contribute to implant rupture or displacement. If you suspect it, see your surgeon for assessment.
Can capsular contracture be treated without surgery, or at home?
Milder cases (Baker I and II) may be managed non-surgically with monitoring, massage, or ultrasound-based therapies under your surgeon’s guidance. There is no genuinely effective home remedy for established, more severe contracture — for moderate to severe (Baker III and IV) cases, surgery, most often capsulectomy, remains the gold standard for a lasting result. Be cautious of any product or technique claiming to reverse capsular contracture entirely without medical supervision.
Is capsular contracture covered on the NHS?
Not as standard, since breast augmentation is a cosmetic procedure — but NHS-funded capsular contracture treatment may be possible where it’s causing significant pain or quality-of-life impact, assessed case by case through your GP and local Integrated Care Board.
