ICD-10: M94.29

Chondromalacia, particularly when classified under ICD-10 code M94.29, refers to the softening and deterioration of cartilage in multiple joints. This condition is often associated with pain and dysfunction, primarily affecting the knee but can also involve other joints. Below is a detailed clinical description and relevant information regarding this diagnosis.

Clinical Description of Chondromalacia

Definition

Chondromalacia is characterized by the degeneration of cartilage, which is the smooth tissue that covers the ends of bones in joints. This degeneration can lead to pain, swelling, and reduced mobility in the affected joints. When the condition is specified as affecting multiple sites, it indicates that more than one joint is involved, which can complicate diagnosis and treatment.

Etiology

The causes of chondromalacia can vary widely and may include:
- Overuse or repetitive stress: Common in athletes or individuals engaged in activities that put excessive strain on the joints.
- Injury: Trauma to the joint can lead to cartilage damage.
- Biomechanical factors: Abnormal joint alignment or movement patterns can contribute to uneven wear on cartilage.
- Age-related degeneration: As individuals age, cartilage naturally wears down, increasing the risk of chondromalacia.

Symptoms

Patients with chondromalacia may experience:
- Joint pain: Often described as a dull ache, particularly during or after activity.
- Swelling: Inflammation around the affected joints may occur.
- Stiffness: Reduced range of motion, especially after periods of inactivity.
- Grinding or popping sensations: Known as crepitus, this can occur during joint movement.

Diagnosis

Diagnosis typically involves:
- Clinical evaluation: A thorough history and physical examination to assess symptoms and joint function.
- Imaging studies: X-rays or MRI scans may be utilized to visualize cartilage condition and rule out other joint issues.

Treatment Options

Management of chondromalacia, especially when it affects multiple sites, may include:
- Physical therapy: Strengthening exercises to support the joint and improve flexibility.
- Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) to alleviate pain and reduce inflammation.
- Activity modification: Adjusting activities to minimize stress on the affected joints.
- Surgical intervention: In severe cases, procedures such as arthroscopy may be considered to repair or remove damaged cartilage.

Prognosis

The prognosis for individuals with chondromalacia varies based on the severity of the condition and the effectiveness of treatment. Early intervention and adherence to a rehabilitation program can lead to significant improvements in symptoms and joint function.

Conclusion

ICD-10 code M94.29 for chondromalacia affecting multiple sites highlights the importance of recognizing and addressing cartilage degeneration in various joints. Understanding the clinical presentation, potential causes, and treatment options is crucial for effective management and improved patient outcomes.
