M00.00
Staphylococcal arthritis, unspecified joint
Clinical Classification Guidelines
Medical Intelligence & Overview
Staphylococcal arthritis is an infection of the joints caused by bacteria called Staphylococcus. It can affect any joint in the body, but most often involves the knees, hips, shoulders, and elbows. The infection can lead to joint pain, swelling, and dysfunction if not treated promptly. This condition is classified under ICD-10 code M00.00 as an unspecified joint affected by staphylococcal bacteria, indicating that the specific joint involved has not been specified in this classification.
Causes & Symptoms
Clinical Causes: Bacterial infection by Staphylococcus bacteria, which can enter the body through cuts, wounds, or other sources of bacteria entry. Spread from other parts of the body through the bloodstream, leading to hematogenous (blood-borne) spread to joints. Direct inoculation into the joint during trauma or surgery. Weakened immune system, making the body more susceptible to bacterial infections. Chronic skin infections or conditions that harbor bacteria and increase the risk of joint infection.
Key Symptoms: Severe joint pain and tenderness, often worsening with movement. Swelling and warmth around the affected joint. Redness of the skin over the joint. Limited range of motion or difficulty moving the joint normally. Fever and chills, indicating systemic infection. General feeling of tiredness or malaise.
Diagnostic & Treatment
Diagnosis Path: Medical history and physical examination focusing on joint tenderness, swelling, and warmth. Blood tests to detect infection markers such as an elevated white blood cell count and inflammatory markers (ESR, CRP). Joint fluid analysis through aspiration (arthrocentesis), where fluid is extracted and tested for bacteria, candida, or other pathogens. Imaging tests such as X-rays, ultrasound, or MRI to visualize joint damage or inflammation, although these are often used to support diagnosis rather than confirm infection.
Treatment Protocols: Antibiotic therapy: Typically involves high-dose antibiotics tailored to target Staphylococcus bacteria, often administered intravenously initially and then orally. Joint drainage: Removal of infected fluid from the joint through aspiration or surgical procedures to reduce bacterial load and relieve symptoms. Supportive care: Rest, ice application, and elevation of the affected limb to reduce swelling and pain. Surgical intervention: In severe or persistent cases, surgery such as joint debridement or even joint replacement may be necessary. Monitoring and follow-up: Regular assessments to ensure infection resolution and to prevent permanent joint damage.
