Other infective (teno)synovitis, left knee
Clinical Classification Guidelines
Medical Intelligence & Overview
Infective (teno)synovitis of the left knee is a condition characterized by inflammation caused by an infection within the joint and nearby tendons. This condition affects the synovial membrane, which lines the joint, and can involve the tendons around the knee. The term 'infective' highlights the infectious origin, typically due to bacteria, fungi, or viruses. Recognizing this condition is important for prompt and effective treatment, which can prevent joint damage and restore function.
Causes & Symptoms
Clinical Causes: Bacterial infections, such as Staphylococcus aureus or Streptococcus species Fungal infections, often in immunocompromised individuals Viral infections affecting the joint tissues Spread from nearby infections or systemic infections Injuries or wounds near the knee that introduce infectious agents Repeated or prolonged joint use leading to micro-injuries susceptible to infection Underlying immune system deficiencies or chronic health conditions
Key Symptoms: Joint pain and tenderness around the knee Swelling and warmth over the affected area Limited range of motion in the knee joint Fever and general feelings of illness Redness and inflammation around the knee Accumulation of fluid within the joint (effusion) Pain that may worsen with movement or pressure
Diagnostic & Treatment
Diagnosis Path: Medical history review and physical examination focusing on knee tenderness and swelling Blood tests to identify infection markers, such as elevated white blood cell count or C-reactive protein Joint aspiration to collect synovial fluid for analysis, culture, and microscopy Imaging studies such as X-rays, ultrasound, or MRI to assess joint damage and inflammation Microbiological testing of the synovial fluid to determine the infectious organism
Treatment Protocols: Antibiotic or antifungal therapy tailored to the identified infectious agent Drainage of infected synovial fluid to relieve pressure and remove infectious material Rest and elevation of the affected limb to reduce swelling Pain management with NSAIDs or other appropriate medications Immobilization of the knee during active infection phase Rehabilitation exercises post-treatment to restore joint mobility and strength Monitoring for signs of recurrent infection or joint damage
