An Overview of Septic Arthritis Symptoms
Septic arthritis is a general term used to describe forms of
arthritis caused by a bacterial infection. It can affect people of any age but is more common in infants and children under the age of three.
The symptoms of septic arthritis (along with their severity) can vary depending on a number of factors, including:
- The age of the person
- The joint or joints involved
- The type of bacteria
- Other conditions a person may have.
For example, infants may not have any localized joint pain, instead presenting with fever and irritability. Others may have very mild symptoms that can delay diagnosis for several months. This is more common in people with a history of a
knee replacement or
hip replacement.
Specific Septic Arthritis Symptoms
Specific symptoms of septic arthritis may include:
- Severe pain within a joint. For septic arthritis in the hip, pain may be referred to the buttock, thigh, or knee.
- Swollen and/or hot joint.
- Decreased movement of the joint.
- A noticeable limp.
- Other common symptoms consistent with a bacterial infection, such as fever, cold sweats, chills, extreme tiredness, and lack of appetite. In infants, irritability may be a symptom of septic arthritis.
