S82.035 Nondisplaced transverse fracture of left patella

Name of the Condition

• Nondisplaced transverse fracture of left patella

Summary

This condition involves a horizontal break across the left kneecap (patella), a triangular bone that protects the knee joint. The fracture line runs perpendicular to the bone’s long axis, and the bone fragments remain aligned in their normal position. Nondisplacement indicates the fracture is stable, with no significant shift of the bone pieces.

Causes

Direct trauma to the knee, such as a fall onto the kneecap, a blow from an object, or a forceful contraction of the quadriceps muscle. High-impact injuries, like those from sports 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 left 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

• Conservative management: Immobilization with a brace or cast to allow healing. Physical therapy to restore strength and mobility once the fracture stabilizes.
• Surgical intervention: Rarely required for nondisplaced fractures, but may be considered if the fracture is unstable or fails to heal with conservative care.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with conservative treatment, though recovery may take several weeks to months. Follow-up appointments monitor healing progress and adjust treatment as needed. Full return to activity depends on the individual’s recovery and adherence to rehabilitation.

Complications

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

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid falls by using assistive devices if balance is impaired.

When to Seek Professional Help

Seek immediate care if pain is severe, swelling worsens, or the knee cannot bear weight. Follow up with a healthcare provider if symptoms persist or worsen after initial treatment.

Tips for Medical Coders

Document the fracture location (left patella) and type (nondisplaced transverse) clearly. Include details on imaging findings, treatment approach, and any complications to support accurate coding. Ensure documentation aligns with clinical guidelines for fracture classification.
