ICD-10: S83.242

The ICD-10 code S83.242 refers to an "Other tear of medial meniscus, current injury, left knee." This classification is part of the broader category of knee injuries, specifically focusing on tears of the medial meniscus, which is a crucial cartilage structure in the knee joint.

Clinical Description

Anatomy and Function

The medial meniscus is a C-shaped cartilage located on the inner side of the knee joint. It plays a vital role in load distribution, shock absorption, and joint stability. Injuries to the medial meniscus can significantly affect knee function and lead to pain, swelling, and reduced mobility.

Types of Meniscal Tears

Meniscal tears can vary in type and severity, including:
- Horizontal tears: These run parallel to the meniscus.
- Vertical tears: These extend from the top to the bottom of the meniscus.
- Complex tears: These involve multiple patterns and can be more challenging to treat.
- Bucket-handle tears: A specific type of vertical tear that can displace a portion of the meniscus.

The designation "Other tear" in the ICD-10 code indicates that the specific type of tear does not fall into the more commonly classified categories, suggesting a unique or less typical injury pattern.

Symptoms

Patients with a medial meniscus tear may experience:
- Pain: Often localized to the inner side of the knee.
- Swelling: Due to inflammation and fluid accumulation.
- Locking or catching: A sensation that the knee is stuck or unable to move freely.
- Instability: A feeling that the knee may give way during activities.

Diagnosis

Diagnosis typically involves:
- Physical examination: Assessing range of motion, swelling, and tenderness.
- Imaging studies: MRI is the preferred method for visualizing meniscal tears, providing detailed images of the knee's soft tissues.

Treatment Options

Treatment for a medial meniscus tear can vary based on the tear's type, location, and severity:
- Conservative management: This may include rest, ice, compression, and elevation (RICE), along with physical therapy to strengthen surrounding muscles.
- Surgical intervention: In cases where conservative treatment fails or if the tear is severe, arthroscopic surgery may be necessary to repair or remove the damaged meniscal tissue.
