M17.11
Unilateral primary osteoarthritis, right knee
Clinical Classification Guidelines
Medical Intelligence & Overview
Unilateral primary osteoarthritis of the right knee, classified under ICD-10 code M17.11, is a common degenerative joint condition that primarily affects the cartilage in one knee. Osteoarthritis involves the gradual breakdown of cartilage, leading to joint pain, stiffness, and reduced mobility. It is termed 'primary' when no specific cause other than aging or genetic factors is identified, and 'unilateral' indicating that only one knee is affected, in this case, the right knee. This condition is prevalent among older adults but can also affect those with previous knee injuries or certain genetic predispositions. Understanding the underlying factors, symptoms, diagnostic methods, and management strategies can help individuals better manage the condition and improve quality of life.
Causes & Symptoms
Clinical Causes: Aging process leading to cartilage deterioration Genetic predisposition influencing cartilage health Previous knee injuries or trauma Overuse or repetitive stress on the knee joint Obesity increasing joint load and wear Misalignment of the knee joint (e.g., bow-legged or knock-kneed deformities) Certain metabolic or inflammatory conditions, though less common in primary osteoarthritis
Key Symptoms: Pain in the affected knee, especially during or after activity Stiffness in the knee, often after periods of inactivity or upon waking Swelling around the knee joint due to inflammation Reduced range of motion, making it difficult to fully bend or straighten the knee A sensation of grinding or crepitus during knee movement Weakness or instability in the knee joint Tenderness when pressing on the knee area Decreased ability to perform daily activities or engage in physical exercise
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a combination of medical history assessment, physical examination, and imaging studies. The healthcare provider will evaluate symptoms, examine the knee for swelling, tenderness, and range of motion, and may use X-rays to visualize joint space narrowing, bone spurs, or deformities characteristic of osteoarthritis. MRI scans might be employed in some cases to assess cartilage health more precisely. Laboratory tests are usually not required unless symptoms suggest other joint disorders. A comprehensive evaluation helps confirm the presence of primary osteoarthritis localized to the right knee and rules out other potential causes of joint pain.
Treatment Protocols: Management of unilateral primary osteoarthritis of the right knee aims to alleviate symptoms and improve joint function. Treatment strategies typically include:
