Calf implants can develop healing or placement problems, although postoperative swelling alone does not mean something has gone wrong. According to Cleveland Clinic, only a small percentage of people who receive calf implants experience significant problems.
When Does Recovery Become a Concern?
Healing problems can include fluid buildup, infection, or a wound that reopens. An implant may later shift or develop firm scar tissue around it. The result can also be disappointing even when healing is medically uncomplicated.
What Is Expected During Early Healing?
We expect swelling, redness, tenderness, and bruising after calf augmentation; they subside over time. Swelling can temporarily make the calves look uneven.
What Complications Can Occur?
Problems can arise during healing or after an implant has been in place for some time. In addition to the findings in the study below, possible risks include blood clots, nerve damage, muscle spasms, and extrusion, in which an implant pushes through the skin. Elective surgery should be postponed if you have an active infection; a condition that could impair healing needs evaluation before surgery.
What Did a 25-Year Review Find?
A 2012 retrospective review by de la Peña-Salcedo and colleagues reported outcomes from 63 patients who received 126 implants using a subfascial technique. The findings describe that surgical series, not the personal odds for every patient or every implant technique.
The review reported these complications:
| Timing | Finding | Reported rate |
|---|---|---|
| Early | Seroma, or fluid buildup | 21.42% |
| Early | Severe postoperative pain | 11.11% |
| Early | Wound dehiscence, or reopening | 7.14% |
| Early | Infection | 0.79% |
| Early | Hematoma | 0% |
| Late | Implant displacement | 3.96% |
| Late | Capsular contracture | 3.17% |
| Late | Numbness at the ankle | 2.38% |
| Late | Implant rupture | 1.58% |
| Late | Implant leaking | 0% |
| Late | Palpable implant | 0% |
A reported rate of 0% means the researchers did not observe that complication in their series, not that it cannot happen.
Which Warning Signs Need Urgent Care?
Call 911 or go to the nearest emergency department for chest pain, shortness of breath, or coughing up blood, which can signal a blood clot in the lungs. Do the same for calf pain that becomes far worse than ordinary postoperative soreness, especially if the calf feels tight or hard or you have numbness, tingling, or pain when moving your foot or toes. These can be signs of acute compartment syndrome, a rare but dangerous buildup of pressure in the leg muscles.
Call your surgical team the same day for new swelling, warmth, or pain in one leg; fever, pus, or spreading redness at an incision; heavy bleeding or excessive swelling or bruising; muscle spasms; or nausea and vomiting. Tell the team when the symptoms began and whether they are worsening.
What Raises the Risk, and How Can You Lower It?
Implant size and placement matter. An implant placed just beneath the skin is more likely to shift or be felt, and overly large implants have been linked to muscle damage. The Aesthetic Society’s calf implant safety guidance also identifies incorrect pocket placement as a possible cause of a visible implant, slippage, or asymmetry. Nicotine can interfere with healing and increase surgical risk.
Choose a board-certified plastic surgeon and an accredited facility, as we discuss in our cosmetic surgery safety guide. Before surgery, discuss an implant size suited to your calves and stop smoking on your surgeon’s timetable. During recovery, follow your instructions for walking, elevating your legs at rest, and wearing compression if prescribed.
When Is Removal or Revision Needed?
The treatment depends on the problem. A surgeon may drain a fluid collection with a needle. An infected implant usually needs removal; a new implant is considered only after the infection clears. A displaced implant may be repositioned or replaced. If firm scar tissue tightens around an implant, a surgeon may release or remove that tissue and replace the implant. A leaking or ruptured silicone-gel implant needs removal and replacement.
Removal without replacement takes away the volume the implant supplied. If shape is the concern, a different implant may be considered instead, as with other options covered in our guide to aesthetic revision procedures.
How Is Surgery Performed?
Calf augmentation adds lower-leg volume and definition with implants. At Salisbury Plastic Surgery, the operation typically takes about one hour, following a consultation with Dr. Deborah Ekstrom. The stages are:
- Consultation: Discuss the calf shape you want and review implant and technique options.
- Incision and pocket: The surgeon makes a small incision in the crease behind the knee and creates a pocket for the implant in the calf.
- Placement and closure: The surgeon positions the implant, closes the incision with sutures, and applies a bandage. The process is repeated on the other side when both calves are treated.
How Is Implant Size Chosen?
We consider your lower-leg proportions and the change you want when selecting an implant. Customized implants are an option for a particular contour, but surgery cannot promise perfectly symmetrical legs.
How Painful Is Calf Implant Surgery?
Soreness and tenderness are expected during early healing, although pain varies between patients. Severe pain was among the early complications recorded in the 25-year review.
Cleveland Clinic notes that discomfort may last several days and that placing an implant beneath the calf muscle can mean a slightly longer, more painful recovery. Its recovery advice includes elevating the legs, using ice packs, and taking acetaminophen-based pain relief as directed.
What Is the Recovery Timeline?
At Salisbury Plastic Surgery, patients can return to most everyday activities within a few days, but should avoid strenuous activity until their calves have healed. Cleveland Clinic estimates a return to work at about two weeks and to most activities within six weeks; running, biking, and strength training may take longer. Swelling can take several months to subside fully. At Salisbury Plastic Surgery, optimal healing typically takes six months, although recovery varies.
How Long Do Calf Implants Last?
Calf implants are intended to remain in place permanently, with no routine replacement schedule. The Aesthetic Society says replacement is generally unnecessary unless a complication occurs. Its procedure guidance notes that solid silicone implants do not leak or tear. Silicone-gel implants, however, may break down over the years, according to Cleveland Clinic. A complication or a decision to change the result may lead to another operation.
Are Calf Implants Worth It If Exercise Has Not Changed Your Calf Shape?
Calf implants may be worthwhile if fuller definition matters to you and exercise has not produced the shape you want. Cleveland Clinic notes that most people are pleased with their results. Even so, the decision involves recovery and surgical risks: a realistic goal is improved volume and proportion, not a guaranteed shape.
Who May Be a Good Candidate?
Calf augmentation may suit someone in overall good health who wants fuller definition in thin, small, or disproportionate calves, particularly when exercise has not produced the desired contour.
Planning Surgery and Follow-Up From Massachusetts
Dr. Deborah K. Ekstrom now performs surgery at our Corona del Mar, California, facility. Our practice team can arrange virtual consultations and follow-up visits for Massachusetts patients and help with flights and accommodations. Ask when it will be safe to fly home: the CDC’s blood-clot risk guidance identifies surgery involving the legs and long periods of sitting as risk factors.
Before arranging travel, useful questions include:
- Which layer will hold the implant, and will it be solid silicone or silicone gel?
- How will the implant size be matched to my calves?
- Whom should I contact, and where should I go, if a problem begins after I fly home?
Frequently Asked Questions
What are calf implants made of, and what is the difference between solid and gel implants?
Calf implants are commonly made of medical-grade silicone, either as solid silicone or as a silicone-gel-filled implant. A surgeon can sculpt a solid implant before placing it, but cannot sculpt a gel-filled one. Implant shapes and sizes also vary, so the choice depends on your leg measurements and goals.
Can calf implants cause numbness?
Yes. Nerve injury is a possible risk, and the 25-year review recorded numbness at the ankle as a late complication. That classification does not tell us when the numbness began or how long it lasted.
How many implants can be placed in each leg?
Depending on leg measurements and the intended contour, a surgeon may place one or two implants in each leg.
Are calf implants only used for cosmetic surgery?
No. Calf implants can also be used to restore lower-leg contour in selected reconstructive cases, including after an injury or for a developmental difference.
Where will the incision scars be?
Incisions are made in the creases behind the knees, where the resulting scars can be less noticeable. Scars will still be present, and their appearance varies as you heal.
When will walking feel normal after calf implant surgery?
Walking may feel stiff and uncomfortable at first, but Cleveland Clinic says your usual walking pattern should return by the second or third week. Walking promotes blood flow, and you may need help moving around for the first couple of days to prevent falls.
Is fat transfer an alternative to calf implants?
Yes, fat transfer is another way to add volume to the lower legs. A surgeon removes fat with liposuction, prepares it, and injects it into the calves; more than one transfer may be needed to achieve the desired look.
If you are considering calf implants or have questions about an existing result, contact Salisbury Plastic Surgery to arrange a consultation with board-certified plastic surgeon Dr. Deborah K. Ekstrom.
