ICD-10: M24.362

Clinical Description of ICD-10 Code M24.362

ICD-10 Code M24.362 refers to a specific diagnosis of pathological dislocation of the left knee, which is categorized under the broader classification of joint derangements. This code is utilized in clinical settings to document and communicate the presence of a dislocation that is not classified elsewhere, indicating that the dislocation is due to pathological conditions rather than trauma or other external factors.

Definition and Characteristics

A pathological dislocation occurs when a joint dislocates due to underlying disease processes, such as degenerative joint disease, inflammatory conditions, or congenital abnormalities. In the case of the left knee, this dislocation can result from various factors, including:

• Degenerative Diseases: Conditions like osteoarthritis can weaken the structures around the knee, leading to dislocation.
• Inflammatory Conditions: Diseases such as rheumatoid arthritis may cause joint instability, resulting in dislocation.
• Neuromuscular Disorders: Conditions that affect muscle tone and control can lead to abnormal joint positioning and dislocation.
• Congenital Anomalies: Some individuals may be born with structural abnormalities that predispose them to dislocations.

Clinical Presentation

Patients with a pathological dislocation of the left knee may present with several symptoms, including:

• Severe Pain: Often acute and localized around the knee joint.
• Swelling and Inflammation: The area may appear swollen due to fluid accumulation and inflammation.
