S82.025 Nondisplaced longitudinal fracture of left patella

Name of the Condition

• Nondisplaced longitudinal fracture of left patella

Summary

A nondisplaced longitudinal fracture of the left patella is a vertical break in the kneecap that remains in its normal position without shifting. This type of fracture involves the bone splitting along its length but does not disrupt alignment, which may allow for conservative management in some cases.

Causes

Direct trauma to the knee, such as a fall onto the kneecap, a forceful blow, or a sudden contraction of the quadriceps muscle. High-impact events like sports injuries or motor vehicle accidents are common triggers.

Risk Factors

• Participation in activities with a high risk of knee injury, such as contact sports or skiing.
• Osteoporosis or other bone-weakening conditions.
• Previous knee injuries or surgeries.
• Advanced age, which may reduce bone density.

Symptoms

• Sudden, severe pain in the knee.
• Swelling and bruising around the kneecap.
• Inability to straighten the knee or bear weight.
• Visible deformity or a gap in the kneecap area.
• A "popping" sensation at the time of injury.

Diagnosis

Physical examination to assess knee movement, swelling, and tenderness. Imaging studies, typically X-rays, to confirm the fracture and evaluate bone alignment. In some cases, a CT scan may be used to assess complex fractures or displacement.

Treatment Options

• Immobilization: Use of a brace or cast to support the knee and allow healing.
• Pain management: Medications to reduce discomfort and inflammation.
• Physical therapy: Exercises to restore strength and mobility once healing progresses.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with conservative treatment, but follow-up imaging may be needed to confirm proper healing. Recovery time varies, typically ranging from several weeks to a few months, depending on the individual's health and adherence to treatment.

Complications

• Delayed healing or nonunion if the fracture does not stabilize.
• Post-traumatic arthritis due to joint damage.
• Chronic pain or stiffness in the knee.

Lifestyle & Prevention

• Wear protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid sudden, forceful movements that strain the knee.

When to Seek Professional Help

Seek immediate care if you experience severe pain, inability to bear weight, or visible deformity after a knee injury. Follow up with a healthcare provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

Document the fracture's nondisplaced status and longitudinal orientation, as well as the left patella involvement, to ensure accurate coding. Include details about the mechanism of injury and any imaging findings to support the diagnosis.
