Clinical Causes: Rheumatoid arthritis, which causes chronic inflammation of joints and surrounding tissues Autoimmune response leading to inflammation of the bursae in the knee Persistent joint stress or overuse in individuals with rheumatoid disease Previous knee injuries that exacerbate inflammation in the context of rheumatoid arthritis Other autoimmune conditions that may contribute to bursitis

Key Symptoms: Pain localized to the front or sides of the right knee, especially when moving or bearing weight Swelling over the affected bursae in the right knee Tenderness when touching the knee Limited range of motion due to discomfort or swelling Warmth and redness over the knee area Persistent achiness or stiffness in the joint, particularly in the morning

Diagnosis Path: Physical examination to assess swelling, tenderness, and range of motion Ultrasound imaging to visualize inflamed bursae and differentiate from other knee issues X-rays to evaluate joint structures and rule out other causes of knee pain Laboratory tests, including blood tests for markers of inflammation and rheumatoid factor levels Aspiration of joint fluid, if necessary, to analyze the fluid for signs of infection or other abnormalities

Treatment Protocols: Nonsteroidal anti-inflammatory drugs (NSAIDs) to decrease pain and inflammation Corticosteroid injections directly into the bursa for rapid relief Physical therapy to improve joint strength, flexibility, and function Rest and activity modification to prevent aggravation of symptoms Application of ice packs to reduce swelling and discomfort In severe or persistent cases, surgical intervention such as bursectomy might be considered Optimal control of rheumatoid arthritis through disease-modifying anti-rheumatic drugs (DMARDs) or biologic agents to manage the underlying autoimmune process
