M25.66

Clinical Causes: Aging-related joint wear and tear Previous injury or trauma to the knee (e.g., fractures, ligament tears) Osteoarthritis and other degenerative joint diseases Inflammatory conditions such as rheumatoid arthritis Infections affecting the knee joint Post-surgical stiffness following knee procedures Overuse or repetitive strain from physical activities Certain autoimmune disorders Poor joint alignment or instability Obesity contributing to increased joint stress

Key Symptoms: Reduced range of motion in the knee Difficulty bending or straightening the knee fully Swelling or inflammation around the joint Pain or discomfort during movement A feeling of tightness or stiffness in the knee Potential warmth or redness over the joint Pain that worsens with activity or after periods of inactivity Possible crepitus, or a grating sensation, during knee movement

Diagnosis Path: A detailed medical history review, focusing on injury history, age, and activity level Physical examination to assess joint movement, swelling, tenderness, and stability Imaging tests such as X-rays to evaluate joint structure and bone health Magnetic resonance imaging (MRI) if soft tissue damage or internal structures are suspected Laboratory tests if infection or autoimmune conditions are considered

Treatment Protocols: Rest and activity modification to prevent further joint injury Application of ice packs to reduce swelling and inflammation Non-steroidal anti-inflammatory drugs (NSAIDs) to alleviate pain and inflammation Physical therapy and targeted exercises to restore joint flexibility and strength Use of assistive devices such as braces or crutches if necessary In some cases, corticosteroid injections for short-term relief Surgical interventions, like arthroscopy, may be considered if conservative treatments fail Addressing underlying conditions such as osteoarthritis or autoimmune disorders
