ICD-10: M11.262

ICD-10 code M11.262 refers to "Other chondrocalcinosis, left knee." This classification falls under the broader category of chondrocalcinosis, which is characterized by the deposition of calcium pyrophosphate dihydrate (CPPD) crystals in the cartilage. This condition can lead to joint pain, swelling, and stiffness, particularly affecting the knees, wrists, and other joints.

Clinical Description

Definition

Chondrocalcinosis is a type of crystal arthropathy that results from the accumulation of calcium pyrophosphate crystals in the cartilage. The term "other chondrocalcinosis" indicates that the condition does not fall under the more common forms, such as pseudogout, which is specifically associated with acute attacks of joint inflammation due to CPPD crystal deposition.

Symptoms

Patients with chondrocalcinosis may experience:
- Joint Pain: Often localized to the affected joint, in this case, the left knee.
- Swelling: Inflammation can lead to noticeable swelling around the joint.
- Stiffness: Reduced range of motion, particularly after periods of inactivity.
- Acute Attacks: Some patients may experience sudden episodes of severe pain and swelling, resembling gout attacks.

Diagnosis

Diagnosis 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, which are indicative of chondrocalcinosis.
- Joint Aspiration: Analysis of synovial fluid can help confirm the presence of CPPD crystals.

Treatment

Management of chondrocalcinosis focuses on alleviating symptoms and may include:
- Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): To reduce pain and inflammation.
- Corticosteroids: In cases of severe inflammation, corticosteroids may be injected into the joint.
