How a normal implant capsule becomes a problem, how Baker grades guide care, and which treatments really work.
A thin capsule of scar tissue forms around every breast implant. Capsular contracture happens when that capsule tightens and squeezes the implant, causing firmness, distortion, or pain.
Doctors grade it from I to IV using the Baker scale. Grades III and IV usually need surgery. Massage and medication have limited evidence, and contracture can return even after treatment.
Maybe one breast feels firmer than it used to. Or one implant seems to sit higher, look rounder, or ache when you lie on it. If you have breast implants, those changes can be unsettling, and capsular contracture is often the first thing people search for.
Here's the reassuring part: a capsule around your implant is completely normal. Your body forms a capsule around any implant. The concern begins only when that capsule tightens.
This guide explains capsular contracture, how to recognize it, how it's graded, and the treatments that can help. It reflects the approach of board-certified plastic surgeon Dr. Siamak Agha in Newport Beach, who regularly treats patients with implant-related concerns.
What Is Capsular Contracture?
Capsular contracture is a tightening of the scar tissue capsule that naturally forms around a breast implant. When the capsule contracts, it squeezes the implant, which can make the breast feel hard, change its shape, or cause discomfort. According to the FDA, it is one of the known risks of breast implants.
The Normal Capsule
Whenever a medical device is placed in the body, the body surrounds it with a thin layer of scar tissue. Around a breast implant, this capsule is usually soft and flexible. It helps hold the implant in place and isn't something you can feel.
When the Capsule Tightens
In some patients, the capsule thickens and contracts over time. Instead of remaining loose around the implant, the capsule compresses it. The result can range from a slightly firmer breast to one that looks visibly distorted. You can learn more about other breast implant complications and how they're managed.
Capsular Contracture Symptoms to Watch For
Capsular contracture symptoms often develop gradually, and they may affect only one breast. Knowing the signs helps you get an evaluation early.
Firmness and Hardness
The most common sign is a breast that feels firmer than before or firmer than the other side. Mild firmness may be the only symptom at first.
Distortion, Round Shape, or a High-Riding Implant
As the capsule tightens, it can push the implant upward or squeeze it into an overly round, ball-like shape. The breast may look less natural, and the two sides may no longer match.
Pain and Tightness
More advanced contracture can cause tightness, tenderness, or pain, especially when lying on your stomach or during exercise.
Early vs. Late Onset
In an ASPS article, plastic surgeon Dr. Kevin Tehrani notes that most cases appear within the first two years after surgery. When contracture appears many years later, he notes that implant rupture is a common cause, which is why late changes deserve an exam.
The Baker Grade Scale, Explained
Surgeons use the Baker scale to describe how severe capsular contracture is. Grade I is a normal, soft breast. Grade II is slightly firm but looks normal. Grade III is firm and visibly distorted. Grade IV is hard, distorted, and often painful. Your grade helps guide whether treatment is needed and which kind.
Grades I and II
Grade I is considered normal. Grade II involves mild firmness that you may feel but others can't see. Many grade II cases are monitored, and some are treated without surgery.
Grades III and IV
Grade III contracture is firm and changes the breast's appearance. Grade IV adds pain and hardness. The FDA notes that grades III and IV may require another operation to correct.
Every implant forms a capsule. The problem starts only when that capsule tightens and begins squeezing.
What Causes Capsular Contracture, and Who Is at Higher Risk?
The exact cause of capsular contracture isn't fully understood. The FDA notes that it appears more often after infection, a hematoma (a collection of blood), or a seroma (a collection of fluid). Several other factors may increase risk.
Biofilm and Low-Grade Bacterial Contamination
A leading theory is that a thin layer of bacteria, called a biofilm, can settle on the implant surface and trigger inflammation that thickens the capsule. This is one reason surgeons take careful steps to keep implants clean during placement.
Hematoma, Seroma, and Radiation
Blood or fluid collecting around the implant after surgery can raise the risk. Radiation therapy for breast cancer also increases the likelihood of contracture, which is an important consideration in breast reconstruction.
Implant Placement and Smoking
Where the implant sits may matter. In the ASPS article, Dr. Tehrani notes that implants placed above the muscle carry a higher lifetime risk than those placed fully beneath it. Smoking can also affect healing and is best avoided.
How Common Is It?
The FDA doesn't publish a single rate, and estimates vary between studies and implant types. In the ASPS article, Dr. Tehrani estimates that about one in six patients develop some degree of contracture. Your surgeon can explain the risk for your specific implant and placement.
Can Capsular Contracture Go Away Without Surgery?
Mild capsular contracture sometimes stays stable, and some grade II cases can be managed without surgery. However, contracture rarely reverses on its own once it reaches grades III or IV. Non-surgical options have limited evidence, and the FDA notes there is no FDA-cleared device specifically for treating it.
Diagnosis Comes First
Capsular contracture is usually diagnosed with a physical exam. If your surgeon suspects an implant rupture, especially with late-onset changes, imaging may be recommended. Getting the right diagnosis helps rule out other causes of firmness or shape change.
Massage
Some surgeons recommend gentle implant massage in the weeks after augmentation. It's best considered a surgeon-directed habit rather than a proven treatment, and you should only do it if your surgeon advises it.
Medication
Some surgeons have tried leukotriene receptor antagonists, such as montelukast, an asthma medication used off-label for contracture. A systematic review has examined its use, but the evidence remains limited, particularly for advanced grades. Montelukast also carries an FDA boxed warning for mental health side effects, as reported by AJMC, so it's something to discuss carefully with your doctor.
Ultrasound Therapy for Mild Cases
For some grade II cases, The One Plastic Surgery Center may monitor the breast or use an ultrasound-based therapy protocol. Grades III and IV are generally treated surgically.
Surgical Capsular Contracture Treatment
Surgery is the most reliable capsular contracture treatment for grades III and IV. Options range from releasing the capsule to removing it completely, often along with replacing or removing the implant. The best approach depends on your grade, implant type, tissue quality, and whether you want to keep implants.
Capsulotomy
In a capsulotomy, the surgeon releases the tight capsule by cutting into it, but does not remove it. This procedure can loosen the pocket, but because the capsule remains, it may not suit every case.
Partial vs. Total Capsulectomy
A capsulectomy removes the capsule. A partial capsulectomy removes part of it, while a total capsulectomy removes all of it. Removing the thickened tissue gives the new or existing implant a fresh pocket.
En Bloc Capsulectomy
In an en bloc capsulectomy, the implant and its surrounding capsule are removed together as a single unit. The practice performs this approach as part of its breast restoration after implant removal procedures.
Implant Exchange and Repositioning
Many patients choose to replace their implants after the capsule is removed. Moving the implant to a new pocket, such as beneath the muscle, may lower the risk of recurrence for some patients. Learn more about breast revision surgery.
Acellular Dermal Matrix Support
When a new implant is placed, Dr. Agha may use an acellular dermal matrix, a supportive tissue material, around it. These materials can help reinforce the pocket and support the result.
Removing Implants for Good: Breast Lift After Removal
Some patients decide they'd rather not have implants again. In those cases, a breast lift after implant removal can reshape the remaining tissue. Board-certified plastic surgeon Dr. Siamak Agha uses his signature internal dermal bra technique in Newport Beach to help restore a natural shape without implants.
Firmness that keeps building, or an implant that rides higher, is worth an exam, not a wait-and-see.
Lowering Your Risk of Recurrence
Capsular contracture can come back, even after successful treatment. The FDA notes that it may recur after correction. A few steps can help lower the risk.
Placement and Surgical Technique
Implant placement, careful handling of the implant, and attention to bleeding during surgery all play a role. If you're planning breast augmentation in Newport Beach, ask your surgeon how they approach these factors.
Healthy Habits and Follow-Up
Avoiding smoking, following your post-operative instructions, and keeping follow-up appointments all support healing. Report any new firmness, shape changes, or pain to your surgeon early, rather than waiting.
The Bottom Line on Capsular Contracture
Capsular contracture is a tightening of the normal capsule around a breast implant. Mild cases may be monitored, but grades III and IV usually need surgery, ranging from capsulectomy with implant exchange to removing implants and lifting the breasts. An early evaluation gives you the most options.

Frequently Asked Questions
Can capsular contracture go away on its own?
Mild contracture may stay stable for a long time, and some grade II cases can be monitored or treated without surgery. Once contracture reaches grades III or IV, it rarely reverses on its own. Surgery is usually the most reliable way to correct advanced cases.
Can capsular contracture come back after surgery?
Yes. Capsular contracture can recur even after successful treatment. Choosing an experienced surgeon, considering implant placement, and following post-operative instructions can help lower the risk of it returning.
Is capsular contracture dangerous?
Capsular contracture is not usually dangerous to your overall health, but it can cause discomfort, pain, and changes in breast appearance. Because late-onset firmness can sometimes signal an implant rupture, any new changes are worth a professional evaluation.
How soon after breast augmentation can capsular contracture happen?
It can develop at any time, but many cases appear within the first two years after surgery. Contracture that develops many years later should be evaluated, since it can be linked to other implant issues such as rupture.
Does capsular contracture always mean replacing my implants?
Not always. Some patients have the capsule removed and their implants exchanged, while others choose to remove their devices entirely and have a breast lift. Your surgeon will help you decide based on your grade, implants, and goals.
