Valgus deformity, classified under ICD-10 code M21.069, refers to a specific type of joint deformity characterized by an outward angulation of the distal segment of a bone or joint, particularly affecting the knee. This condition is often described in clinical settings as a misalignment where the knee angles inward while the feet remain aligned, resembling a "knock-kneed" appearance.

Clinical Description

Definition and Characteristics

Valgus deformity is a condition where the angle between the long axis of the bone and the joint is greater than normal. In the case of the knee, this results in the lower leg being angled away from the midline of the body. The term "not elsewhere classified" indicates that this specific type of valgus deformity does not fall under more specific categories or classifications within the ICD-10 coding system, making M21.069 a catch-all for unspecified cases of knee valgus deformity[1][2].

Etiology

The causes of valgus deformity can vary widely and may include:
- Congenital Factors: Some individuals may be born with structural abnormalities that predispose them to valgus deformity.
- Acquired Conditions: Conditions such as arthritis, trauma, or previous surgeries can lead to the development of this deformity over time.
- Biomechanical Factors: Abnormalities in gait or foot structure can contribute to the development of knee valgus.

Symptoms

Patients with valgus deformity may experience a range of symptoms, including:
- Pain in the knee joint, particularly during movement or weight-bearing activities.
- Swelling around the knee.
- Difficulty with balance and stability, especially during physical activities.
- Increased wear and tear on the knee joint, potentially leading to osteoarthritis over time.
