This condition can be described using various alternative names and related terms that reflect its clinical significance and anatomical implications. Below are some of the commonly used terms associated with this diagnosis:

Alternative Names

1. Lateral Patellar Dislocation: This term emphasizes the direction of the dislocation, indicating that the patella (kneecap) has moved laterally (to the outside of the knee).
2. Right Patellar Dislocation: A straightforward term that specifies the location of the dislocation as being on the right knee.
3. Lateral Dislocation of the Patella: A more general term that can apply to either knee but is often used in the context of the right knee when specified.
4. Patellar Subluxation: While this term refers to a partial dislocation, it is sometimes used interchangeably with dislocation in clinical discussions.

Related Terms

1. Patellofemoral Instability: This term describes a broader condition where the patella is prone to dislocation or subluxation due to instability in the patellofemoral joint.
2. Medial Patellofemoral Ligament (MPFL) Injury: The MPFL is crucial for stabilizing the patella; injuries to this ligament are often associated with dislocations.
3. Knee Dislocation: Although this term generally refers to a more severe condition involving multiple structures of the knee, it can be related to patellar dislocations in discussions of knee injuries.
4. Acute Patellar Dislocation: This term is used to describe a recent occurrence of dislocation, distinguishing it from chronic or recurrent dislocations.

Clinical Context

Understanding these alternative names and related terms is essential for healthcare professionals when diagnosing and treating patients with knee injuries. The terminology can influence treatment decisions, rehabilitation protocols, and coding for insurance purposes. For instance, the management of a lateral dislocation may involve surgical interventions such as Medial Patellofemoral Ligament Augmentation Repair, which aims to restore stability to the patella and prevent future dislocations[3][7].

In summary, the ICD-10 code S83.014 encompasses a specific injury with various alternative names and related terms that reflect its clinical implications and treatment considerations.

Lateral dislocation of the right patella, classified under ICD-10 code S83.014, is a common knee injury that typically occurs due to trauma or excessive stress on the knee joint. The treatment approaches for this condition can vary based on the severity of the dislocation, the presence of associated injuries, and the patient's overall health. Below is a comprehensive overview of standard treatment approaches for this condition.
