S82.024A Nondisplaced longitudinal fracture of right patella, initial encounter for closed fracture

Name of the Condition

• Nondisplaced longitudinal fracture of right patella, initial encounter for closed fracture

Summary

A nondisplaced longitudinal fracture of the right patella is a vertical break in the kneecap that remains in its normal position. This type of fracture involves the bone splitting along its length without shifting, maintaining alignment. It is classified as a closed fracture, meaning the skin is intact, and it is documented as the initial encounter for treatment.

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

A 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 keep the knee straight and allow healing.
• Pain management: Medications to reduce discomfort and inflammation.
• Physical therapy: Exercises to restore strength and mobility once healing progresses.
• Surgery: Rarely required for nondisplaced fractures, but may be considered if alignment changes.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with conservative treatment. Full recovery typically takes 6–8 weeks, with gradual return to normal activities. Follow-up appointments monitor healing and adjust treatment as needed.

Complications

• Delayed healing or nonunion.
• Post-traumatic arthritis.
• Chronic pain or stiffness.
• Infection (rare, especially if surgery is performed).

Lifestyle & Prevention

• Wear protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid sudden, forceful movements that strain the knee.
• Use proper techniques in sports or physical labor.

When to Seek Professional Help

Seek immediate care if pain worsens, swelling increases, or the knee cannot bear weight. Contact a healthcare provider if symptoms persist beyond expected healing time or if new symptoms develop.

Tips for Medical Coders

Document the fracture as nondisplaced and specify the right patella. Note the initial encounter and closed fracture status. Ensure clinical documentation supports the absence of displacement and confirms the fracture type.
