Clinical Description

Definition

The term "derangement" in this context indicates a disruption in the normal structure or function of the medial meniscus, which is a C-shaped cartilage located in the knee joint. The medial meniscus plays a crucial role in load distribution, shock absorption, and joint stability. An "old tear or injury" suggests that the damage occurred in the past and may have led to ongoing symptoms or complications.

Symptoms

Patients with this condition may experience a variety of symptoms, including:
- Knee Pain: Often localized to the medial aspect of the knee.
- Swelling: Due to inflammation or fluid accumulation in the joint.
- Stiffness: Reduced range of motion, particularly after periods of inactivity.
- Locking or Clicking Sensations: These may occur during movement, indicating that torn meniscal tissue may be interfering with joint mechanics.

Diagnosis

Diagnosis typically involves a combination of:
- Clinical Examination: Assessment of knee stability, range of motion, and specific tests (e.g., McMurray's test) to evaluate meniscal integrity.
- Imaging Studies: MRI is the preferred method for visualizing meniscal tears and assessing the extent of derangement. X-rays may be used to rule out other conditions, such as fractures or arthritis.

Treatment Options

Management of derangement of the medial meniscus can vary based on the severity of symptoms and the degree of functional impairment. Treatment options may include:
- Conservative Management: Rest, ice, compression, and elevation (RICE), along with physical therapy to strengthen surrounding muscles and improve joint function.
- Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) may be prescribed to alleviate pain and reduce inflammation.
- Surgical Intervention: In cases where conservative treatment fails, arthroscopic surgery may be considered to repair or remove the damaged meniscal tissue.
