Clinical Classification Guidelines
Medical Intelligence & Overview
Other infective bursitis of the knee, classified under ICD-10 code M71.16, is a condition characterized by inflammation of the bursae—small fluid-filled sacs that cushion and reduce friction between tissues—specifically in the knee joint. When this bursitis is caused by an infection, it can lead to swelling, pain, and limited movement. Recognizing the signs and understanding the causes and treatment options are essential steps in managing the condition effectively.
Causes & Symptoms
Clinical Causes: Bacterial infection entering the bursa through a direct wound or penetrating injury to the knee. Spread of infection from nearby skin or soft tissue infections. Repeated knee trauma or stress that makes the bursa more susceptible to infection. Underlying medical conditions that weaken the immune system, increasing infection risk. Invasive procedures or injections into the knee joint or bursae.
Key Symptoms: Swelling and tenderness around the knee. Warmth and redness over the affected area. Localized pain that worsens with movement or pressure. Limited range of motion and stiffness in the knee. Possible fever or chills if the infection is systemic. In some cases, pus may be present if the bursitis becomes abscessed.
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a comprehensive clinical evaluation, including a physical examination of the knee and assessment of symptoms. Imaging studies such as ultrasound or MRI may help visualize swelling and rule out other joint conditions. Additionally, aspiration of fluid from the bursa for laboratory analysis can identify the causative bacteria, confirming the infectious nature of the bursitis. Blood tests might also be ordered to detect signs of systemic infection.
Treatment Protocols: Management of infective bursitis of the knee typically includes medical interventions such as:
