Redness of the skin on the knees: causes, symptoms, and treatment
About the symptom
Redness of the skin on the knees is a common symptom that can be caused by various reasons. This condition is often accompanied by itching, swelling, and even pain, which can significantly impair the patient’s quality of life. The causes of redness can range from allergic reactions to cosmetics and detergents to inflammatory diseases such as dermatitis, eczema, or psoriasis. It is important to consider that skin redness can also indicate an infection or injury, which requires immediate medical attention.
However, redness of the skin on the knees is not always a sign of a serious problem. In some cases, it may occur as a result of prolonged sitting, friction against clothing, or mechanical damage to the skin. If the redness is not accompanied by other symptoms and resolves in a short period, then most likely no medical intervention is needed. Nevertheless, in the case of persistent or worsening redness, it is advisable to consult a specialist for a more detailed examination and diagnosis.
Diseases
Redness of the skin on the knees can be a symptom of various diseases that require careful examination. One of the most common causes is psoriasis, a chronic condition characterized by the formation of red, scaly patches on the skin. Although psoriasis most often affects the skin of the elbow folds and knees, it can manifest in various areas of the body, causing discomfort and itching.
Another cause of redness can be mycoses — fungal infections that often present as inflammatory processes on the skin, including the knees. Additionally, varicose veins can lead to redness and swelling in the knee area, requiring professional medical assistance for diagnosis and treatment.

- eczema
- Mycoses (fungal infections)
- Varicose veins
- Contact dermatitis
- Arthritis (rheumatoid, osteoarthritis)
- Systemic lupus erythematosus
- Guillain-Barré syndrome
Diagnosis
The diagnosis of redness of the skin on the knees requires a comprehensive approach, as this symptom can be caused by various reasons, from minor allergic reactions to serious diseases. First of all, the doctor conducts a physical examination, paying attention to the nature of the redness, the presence of swelling, rash, or other skin changes. A medical history is also collected, which includes information about possible allergic triggers, levels of physical activity, and the presence of other accompanying symptoms.
Depending on the initial examination, the doctor may require additional diagnostic procedures to clarify the cause of the redness. This may include blood tests to check for inflammatory markers or infections, allergy tests to identify possible allergens, as well as ultrasound or MRI if there is suspicion of joint pathologies. Establishing an accurate diagnosis will help select the most effective treatment and improve the overall condition of the patient.
- Complete blood count
- Biochemical blood analysis
- Allergy tests
- Ultrasound of the knee joint
- Magnetic resonance imaging (MRI)
- Skin tests and scrapings
Which doctor to consult
If you notice redness of the skin on your knees, it is important not to ignore this symptom, as it may indicate various diseases or conditions that require medical intervention. Initially, it makes sense to consult a therapist who will conduct a primary examination and help determine the possible causes of the redness. The therapist may refer you to specialized specialists if necessary.
Depending on the suspected cause of the redness, you may need consultations with a dermatologist, rheumatologist, or allergist. A dermatologist will be able to assess the condition of the skin and prescribe appropriate treatment if the redness is caused by dermatological issues such as eczema, psoriasis, or contact dermatitis. The rheumatologist, in turn, will focus on possible systemic diseases such as arthritis. The allergist will help identify allergic reactions that may be causing the redness of the skin.

Types of Knee Skin Redness
Knee skin redness can manifest in various forms and indicate different pathologies. It can be localized or widespread throughout the knee area. Localized redness is often associated with local inflammatory processes, while diffuse redness may suggest systemic diseases or allergic reactions. It is important to note that the nature of the redness and accompanying symptoms can provide the doctor with important information for diagnosis.
One type of redness is erythema, which is accompanied by swelling and itching. Pustular redness may also occur, associated with infectious diseases such as impetigo. Allergic reactions to cosmetics or environmental allergens can cause hives and redness. Each of these manifestations requires special attention and proper treatment to avoid complications.

Causes of Redness in the Skin of the Knees
Redness of the skin on the knees can occur for various reasons, and it is important to assess it in the context of other symptoms and overall health. One of the most common causes of redness is inflammation, which can be triggered by an allergic reaction to cosmetics, detergents, or fabrics. Additionally, mechanical effects, such as constant friction against a surface while kneeling, can lead to localized irritation and redness.
Infectious diseases can also cause redness in the knee area. Skin infections, such as boils or impetigo, may present not only with redness but also with swelling, tenderness, or pus formation. Inflammatory joint diseases, such as arthritis, can also cause redness of the skin around the knee, which is associated with an inflammatory process beneath the skin. If redness occurs without a diagnosed cause, it is important to consult a doctor to identify the exact reason and prescribe appropriate treatment.
- Allergic reactions.
- Mechanical irritation.
- Infectious diseases (boils, impetigo).
- Inflammatory joint diseases (arthritis).
- Psoriasis or eczema.
Common Related Pathologies

Expert Opinion
Redness of the skin on the knees is one of the symptoms that can signal various diseases or conditions of the body. From a dermatological perspective, it is important to consider that this sign can be either temporary and caused by external factors, or chronic, indicating more serious pathologies. Some patients may experience discomfort, itching, or even pain in the area of redness, which necessitates consulting a specialist for a more detailed investigation and diagnosis.
Experts note that during the initial examination, it is important to assess not only the area of redness itself but also accompanying symptoms such as swelling, peeling, or the presence of a rash. These aspects will help the doctor determine whether the redness is the result of an allergic reaction, an infection, or another disease, such as arthritis. It is important not to ignore such manifestations, as timely diagnosis and treatment can significantly alleviate the patient’s condition and prevent the development of chronic diseases.
Treatment of Redness of the Knee Skin
The treatment of redness of the knee skin depends on the cause of this symptom. It is important to consult a doctor for an accurate diagnosis, as redness may be a consequence of various conditions, including dermatitis, eczema, or infectious processes. Timely consultations can prevent the worsening of the condition and choose the most effective treatment methods.
Depending on the established diagnosis, treatment may include medications, physiotherapy procedures, and even lifestyle changes. For example, in cases of allergic reactions, antihistamines and steroid ointments may be prescribed, while infectious inflammations require the use of antibiotics. Equally important is skincare, which includes moisturizing and protection from unfavorable factors.
- Medication treatment (antibiotics, anti-inflammatory agents)
- Physiotherapy (laser therapy, UV irradiation)
- Moisturizing and protective skin products
- Diet and lifestyle changes (more vitamins, fewer allergens)
- Consultations with a dermatologist and allergist
Complications
Redness of the knee skin can be not only a symptom of superficial diseases but also an indicator of more serious pathologies. It is important to understand that ignoring this symptom in some cases can lead to significant complications. For example, if the redness is caused by an infection, such a condition may lead to the spread of the infection to other tissues and organs, which in turn can cause serious diseases such as osteomyelitis or sepsis.
Additionally, chronic redness may be associated with inflammatory processes in the joint, such as arthritis. Without proper treatment, this can cause cartilage damage, limited joint mobility, and ultimately lead to disability. Therefore, it is important to seek medical help in a timely manner and receive the necessary diagnostics.
- Osteomyelitis
- Sepsis
- Arthritis
- Chronic joint pain
- Cartilage damage
