Guide to Breast Implant Capsular Contracture: Grading, Avoidance, and Treatment

Whenever an implant is placed in the body, the body forms a thin layer of scar tissue — a “capsule” — around it. That is normal, and in most of my breast augmentation patients the capsule stays soft and unnoticeable. Capsular contracture is the term I use when that capsule thickens and tightens, squeezing the implant. Depending on severity, it can make the breast feel firm, sit higher or look rounder than intended, or become uncomfortable.

I grade it with the Baker classification, from Baker I (soft, normal) to Baker IV (hard, distorted, and painful). Baker III and IV are the grades that usually prompt a conversation about treatment. Capsular contracture matters because it is one of the most frequent reasons patients need revision after augmentation — a point emphasized in a 2024 systematic review in Plastic and Reconstructive Surgery.¹

Why it happens

The exact cause isn’t fully settled, but the leading, widely taught idea is that low-grade bacterial contamination of the implant surface (a “biofilm”) drives chronic inflammation that thickens the capsule. Bleeding around the implant, the implant surface, the pocket, and possibly the incision have all been studied as contributors. That is why so much of how I perform augmentation is built around keeping the implant pocket as clean as possible.

Does the incision or pocket change the risk?

This comes up in almost every consultation. A meta-analysis comparing incision approaches reported differences in capsular contracture rates between the periareolar incision and the inframammary and transaxillary approaches.² Placement relative to the muscle (subglandular versus dual-plane) has also long been discussed. Because the evidence has real nuance, I review these trade-offs with each patient rather than applying one rule to everyone — you can see the options on my incision and placement sections.

How I work to prevent it

There is no way to guarantee a capsule stays soft, but I use a bundle of measures aimed at minimizing contamination and inflammation on every augmentation: meticulous, atraumatic technique, careful control of bleeding, steps to limit implant handling and skin contact, and thoughtful implant and pocket selection. A recent systematic review and meta-analysis continues to examine which factors most influence contracture rates.³

How it’s treated

If significant (Baker III/IV) contracture develops, it is treatable. The 2024 Plastic and Reconstructive Surgery review concluded that removing or releasing the capsule (capsulectomy or capsulotomy), exchanging the implant, and changing the implant plane appear to be useful ways to reduce recurrence, while also noting that high-quality comparative evidence is still limited.¹ The right approach depends on your specific situation, and I plan it with you at consultation. Most manufacturer warranties also cover Baker III/IV contracture within a defined window — one reason I review implant warranties with every patient.

When to call me

Reach out if a breast becomes firmer, higher, misshapen, or painful — whether it is months or years after surgery. Early evaluation gives you the most options.
