ICD-10: M11.26

Chondrocalcinosis is a condition characterized by the deposition of calcium pyrophosphate dihydrate (CPPD) crystals in the cartilage, leading to joint pain and inflammation. The ICD-10 code M11.26 specifically refers to "Other chondrocalcinosis" affecting the knee, which is a subset of the broader category of chondrocalcinosis.

Clinical Description

Definition

Chondrocalcinosis is often associated with a type of arthritis known as pseudogout, which can cause acute joint inflammation similar to gout but is due to different crystal deposits. The condition can affect various joints, but when it involves the knee, it can lead to significant discomfort and functional impairment.

Symptoms

Patients with M11.26 may experience:
- Joint Pain: Sudden onset of pain in the knee, which can be severe.
- Swelling: The affected knee may become swollen and tender to touch.
- Stiffness: Reduced range of motion in the knee joint, particularly after periods of inactivity.
- Warmth and Redness: The skin over the knee may appear warm and red during acute episodes.

Causes

Chondrocalcinosis can arise from several factors, including:
- Metabolic Disorders: Conditions such as hyperparathyroidism or hemochromatosis can predispose individuals to calcium crystal deposition.
- Genetic Factors: Familial forms of chondrocalcinosis exist, indicating a hereditary component.
- Age: The prevalence of chondrocalcinosis increases with age, often affecting older adults.

Diagnosis

Diagnosis of M11.26 typically involves:
- Clinical Evaluation: A thorough history and physical examination to assess symptoms and joint function.
- Imaging Studies: X-rays may reveal calcifications in the cartilage, while MRI can provide detailed images of joint structures.
- Joint Aspiration: Analysis of synovial fluid can confirm the presence of CPPD crystals.

Treatment

Management of chondrocalcinosis, particularly in the knee, may include:
