M65.16

Clinical Causes: Bacterial infection, often spreading from skin or other infected areas Direct trauma or injury to the knee, introducing infectious agents Spread from systemic infections through bloodstream Repeated or intensive strain on the knee joint, predisposing to infection Compromised immune system, reducing the body's ability to fight infections Previous surgeries or injections in the knee area

Key Symptoms: Localized pain around the knee, often worsening with movement Swelling and tenderness over the affected tendons and synovial lining Redness and warmth of the skin around the knee Reduced range of motion, including difficulty fully bending or extending the knee Fever and general malaise in some cases, indicating systemic infection Possible pus drainage if abscess formation occurs

Diagnosis Path: To confirm infective teno-synovitis of the knee, clinicians typically perform a combination of clinical assessments and diagnostic tests. These include physical examination focusing on swelling, tenderness, and mobility, as well as laboratory studies such as blood tests to detect infection markers. Imaging techniques like ultrasound or MRI may be employed to visualize inflammation, fluid collections, or damage within the knee joint and surrounding tissues. In some cases, synovial fluid aspiration and laboratory analysis are necessary to identify the causative pathogen.

Treatment Protocols: Management of infective teno-synovitis of the knee generally involves a combination of approaches. Antibiotic therapy tailored to the specific infectious agent is essential to eradicate the infection. In cases with significant fluid accumulation or abscess formation, drainage procedures may be performed to remove pus and relieve pressure. Rest and immobilization of the knee can help reduce strain and facilitate healing. Physical therapy might be recommended once the infection is under control to restore movement and strength. In severe or resistant cases, surgical intervention may be necessary to remove damaged tissue or debride infected areas to prevent further joint destruction.
