The knees are just one of the many locations warts on the human body inhabit. While not an area of sensitive skin, they can still be frustrating to deal with, particularly if they grow large. Suffering from warts on knee areas can make wearing shorts or skirts anxiety inducing due to visibility, but they are harmless. Dealing with a wart of this nature is as simple as identifying your wart and determining the best treatment approach to dealing with this problem. Luckily, this is rarely a difficult endeavor as many OTC wart treatment options exist.


The first step before worrying about what appears to be a wart on your knees is to make sure the affliction in question is truly a wart.

Warts are usually a flesh colored raised bump on the skin. The surface part of the wart may feel very rough and grainy or be completely smooth with a finger sliding across it easily. Warts that have not been irritated by friction or trauma to it or the skin around it will not hurt when touched or manipulated.

Warts on kneeNot all warts are flesh-colored; they can also be:

  • Pink,
  • Grey,
  • Brown,
  • White,
  • Yellow,
  • Black.

Warts can show up alone or in groups, though this will not be sudden. Supposed warts that appear suddenly in moments are more likely a rash or allergic reaction to something. Warts that most often occur on the knees have a look similar to cauliflower. There are other wart types as well, so warts lacking this feature do not necessarily remove the possibility of being a wart.

What causes them?

All warts are caused by the human papillomavirus, and this includes knee warts. HPV has over 100 different strains, some of them cause cancer, and the others cause warts. Rest assured that wart causing strains are low risk and do not cause cancer. Warts themselves are harmless and rarely cause any issues besides being cosmetically ugly to look at. Warts usually go away by themselves within a year but in some cases may persist until removal while spreading or increasing in size.

Knee warts are always caused by the human papillomavirus.

HPV, the virus that causes these warts, is highly contagious and warts are the way this virus spreads. It is important to note that when you spread your knee wart, the newly infected individual’s warts may not appear on the knee. It is actually just the virus you are spreading and warts, if they even occur, may show up anywhere such as the fingers or thighs. Thigh skin can be more sensitive than that of the knees. To learn more about treatments appropriate for warts on thigh areas, see this article.

Most wart spreading from person to person is from an uninfected party touching another person’s wart. Other ways to get HPV and therefore warts are transfer via something the wart touched.

HPV can spread easiest when personal hygiene items are shared such as:

  • Shared razors,
  • Shared washcloths,
  • Shared towels,
  • Any other items that come into contact with warts covered skin.

They come in different types

There are two different types of warts that typically appear on the knees. The first type is called the common wart. These warts have the stereotypical cauliflower-like appearance. Wart on kneeMost knee warts will be common warts as these favor joint areas such as the elbows, knees, and knuckles. Common warts often appear singly, or in smaller groups. They will cause no pain or discomfort unless subjected to pressure and friction frequently.

The second type of wart known to occur on the knees is the flat wart. These warts are often called juvenile warts as they are extremely common in children. Having flat warts as an adult is nothing to panic about it is just less common. Flat warts can be identified by their smooth, flattened surface as well as the number of warts in the area. Unlike common warts, flat warts frequently appear in large numbers from a low dozen to over 100 in one spot.

Having flat warts is not the end of the world, and like most warts, they usually go away within a few months or up to a year. Flat warts seem to make up for their small size with sheer numbers of warts, and this is why they tend to be more frustrating than common warts. If you have flat warts on your knees, you likely have a lot of them, and so this may limit some treatment approaches you are considering.
