A capsulectomy is a surgical procedure that removes the scar tissue capsule your body naturally forms around an implant or, in orthopedic cases, releases a tightened joint capsule that restricts movement. The term comes up most often in the context of breast implants, where the body builds a shell of fibrous tissue around the implant over time. When that shell causes problems, such as pain, hardening, or rare cancerous changes, a surgeon removes part or all of it.
Why Your Body Forms a Capsule
Whenever a foreign object is placed inside the body, the immune system responds by surrounding it with a layer of scar tissue called a capsule. This is a normal biological response and happens with every breast implant. In most people, the capsule stays thin and soft and never causes trouble. In others, the capsule thickens, tightens, and squeezes the implant, a condition called capsular contracture. Surgeons grade contracture severity on a four-point Baker scale:
- Grade I: The breast looks and feels completely natural.
- Grade II: A surgeon can detect slight firmness, but the patient has no complaints.
- Grade III: The patient notices firmness in the breast.
- Grade IV: The breast is visibly distorted, hard, and often painful.
Capsulectomy is typically considered once contracture reaches Grade III or IV, or when other complications develop. A Grade III or IV rating is also the threshold most insurance companies and implant manufacturers use to classify the procedure as medically necessary rather than cosmetic.
Types of Breast Capsulectomy
Not every capsulectomy is the same. The three main approaches differ in how much tissue is removed and why.
Partial Capsulectomy
The surgeon removes only part of the capsule, usually the thickened front portion that is causing the most contracture. This is a less extensive operation but carries a higher chance of contracture returning. One study found a 50% recurrence rate after partial capsulectomy compared to 11% after total capsulectomy.
Total Capsulectomy
The entire capsule is removed. The implant may be taken out first to give the surgeon better access, or the capsule may be peeled away with the implant still inside. Removing the complete capsule reduces the chance that silicone residue or bacterial film left behind could trigger further problems. Total capsulectomy is the most common approach for capsular contracture and for patients requesting implant removal due to systemic symptoms sometimes called breast implant illness.
En Bloc Capsulectomy
This is the most precise version: the implant and the entire surrounding capsule are removed together in one intact piece, along with a margin of healthy tissue around it. The term “en bloc” comes from cancer surgery and is properly used only when treating a confirmed or suspected tumor. It is the gold standard for breast implant-associated anaplastic large cell lymphoma (BIA-ALCL), a rare cancer linked to textured implants. Some patients without cancer request an en bloc procedure, but surgeons generally describe non-cancer operations as total capsulectomy rather than en bloc, since the oncologic margin of healthy tissue is not needed.
When Capsulectomy Is Medically Necessary
The procedure is not always cosmetic. Major insurers, including Aetna, Cigna, UnitedHealthcare, and Molina, cover capsulectomy when at least one of these conditions is documented: Baker Grade IV contracture causing pain or interfering with mammography, persistent infection that antibiotics cannot resolve, tissue death around the implant, or a diagnosis of BIA-ALCL. For BIA-ALCL specifically, UnitedHealthcare also covers capsulectomy for patients with certain recalled textured implants even before cancer develops, due to elevated risk.
BIA-ALCL itself, while rare, is treated aggressively. Current clinical recommendations call for implant removal and en bloc capsulectomy at every stage of the disease, from Stage I through Stage IV. After the capsule is removed in a BIA-ALCL case, placing any new implant is not recommended.
What Happens During the Procedure
Breast capsulectomy is performed under general anesthesia. The surgeon typically uses a needle-tip cautery tool guided by a headlamp to carefully dissect the capsule away from surrounding tissue. The anterior (front) portion of the capsule sits just behind the breast gland, while the posterior (back) portion may be adhered to the chest wall muscles, particularly in patients who have had multiple prior surgeries. In those cases, the surgeon must work cautiously to avoid injuring the intercostal muscles or blood vessels beneath.
When the capsule is being removed intact with the implant inside, surgeons often start with the upper portion of the capsule, where dissection tends to be easier with the implant still providing structure. If the capsule is dangerously stuck to the chest wall, the surgeon may open the capsule, remove the implant first, and then complete the capsulectomy in stages to reduce the risk of puncturing the lung cavity. After the capsule is fully out, the surgical site is checked for bleeding and drains are placed under the skin to collect excess fluid.
Risks and Complication Rates
Capsulectomy is a safe procedure, but it carries higher complication rates than simpler capsule operations like capsulotomy (where the capsule is scored or cut but not removed). An analysis of 7,486 patients found the following complication rates for capsulectomy:
- Hematoma (blood collection): 1.00% per breast
- Seroma (fluid collection): 0.83% per breast
- Pneumothorax (collapsed lung): 0.06% of patients, rising to 0.10% in some subgroup analyses
By comparison, capsulotomy patients had hematoma and seroma rates of 0.56% each and zero cases of pneumothorax. The pneumothorax risk, while very low, is unique to capsulectomy because of the deep dissection required along the chest wall. It occurred exclusively in reconstructive patients rather than cosmetic ones in that dataset.
Recovery Timeline
Recovery generally takes two to six weeks, depending on whether one or both implants were removed and whether additional reconstruction was done at the same time. Surgical drains are usually removed within a few days. Your surgeon will give specific instructions about which movements and activities to avoid during healing, particularly overhead reaching and lifting. Patients who have the implants removed without replacement (sometimes called explant surgery) tend to recover faster than those who undergo immediate reconstruction with tissue flaps.
Recurrence After Capsulectomy
If you have a new implant placed after capsulectomy, there is a meaningful chance the body will form a problematic capsule again. Recurrence rates in studies vary widely, from 0% to as high as 53%, depending on the surgical technique, implant type, and follow-up period. One commonly cited study reported a 34% recurrence rate after capsulectomy when new implants were placed. Another found a 30.7% recurrence rate when new textured saline implants were placed under the chest muscle after capsulectomy.
Total capsulectomy appears to perform better than partial. One study found an 11% recurrence rate after total capsulectomy versus 50% after partial removal, though the total capsulectomy group had shorter follow-up. Some studies using steroid treatments alongside capsulectomy reported zero recurrences, suggesting that managing inflammation after surgery may play a role in preventing the capsule from reforming aggressively.
Capsulectomy in Orthopedic Surgery
Outside of breast surgery, capsulectomy (more often called capsular release) is used to treat frozen shoulder and other joint conditions where the capsule surrounding a joint becomes inflamed, scarred, and painfully tight. In frozen shoulder, the tissue lining the shoulder joint thickens and contracts, restricting range of motion and causing chronic pain that can interfere with daily activities and work.
Most frozen shoulder cases are first treated with physical therapy and corticosteroid injections for at least four months. When conservative treatment fails, arthroscopic capsular release is the standard surgical option. Through small incisions, the surgeon uses a camera and cautery tool to cut away thickened ligaments and scar tissue inside the joint, carefully staying within 10 millimeters of the socket rim to avoid damaging the nerve that runs beneath the shoulder. The extent of the release is tailored to each patient based on where their motion is most restricted. Studies show favorable outcomes across all causes of frozen shoulder, whether the condition developed on its own, after an injury, or following a previous surgery.
