ICD-10: S83.001

The ICD-10 code S83.001 refers to an unspecified subluxation of the right patella. This code is part of the broader classification of knee injuries and disorders, specifically focusing on the patella, or kneecap, which plays a crucial role in knee function and stability.

Clinical Description

Definition of Subluxation

A subluxation is defined as a partial dislocation of a joint, where the surfaces of the joint are misaligned but still maintain some degree of contact. In the case of the patella, this condition can lead to pain, instability, and impaired mobility. The subluxation may occur due to trauma, overuse, or underlying anatomical issues.

Symptoms

Patients with an unspecified subluxation of the right patella may experience a variety of symptoms, including:
- Knee Pain: Often localized around the kneecap, which may worsen with activity.
- Swelling: Inflammation around the knee joint can occur.
- Instability: A feeling that the knee may give way during movement.
- Limited Range of Motion: Difficulty in fully extending or bending the knee.
- Crepitus: A grinding sensation or sound during knee movement.

Causes

The causes of patellar subluxation can vary and may include:
- Trauma: Direct impact or injury to the knee.
- Repetitive Stress: Activities that place excessive strain on the knee joint.
- Anatomical Factors: Variations in the alignment of the bones or soft tissues around the knee, such as muscle imbalances or ligament laxity.

Diagnosis

Diagnosis of an unspecified subluxation of the right patella typically involves:
- Clinical Examination: Assessment of knee stability, range of motion, and pain levels.
- Imaging Studies: X-rays or MRI may be utilized to visualize the patella's position and assess any associated injuries to the surrounding structures.
