S82.031A Displaced transverse fracture of right patella, initial encounter for closed fracture

Name of the Condition

• Displaced transverse fracture of right patella, initial encounter for closed fracture

Summary

This condition involves a horizontal break across the right kneecap (patella), with the bone fragments displaced from their normal alignment. The fracture is closed, meaning the skin is intact, and this is the initial encounter for treatment. The patella, a triangular bone protecting the knee joint, is fractured transversely, with the break running perpendicular to its long axis.

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 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 cast or brace to allow healing, followed by physical therapy to restore function.
• Surgical intervention: Internal fixation to realign and stabilize the bone fragments, often using screws or wires, if displacement is significant.

Prognosis and Follow-Up

With proper treatment, most patients recover fully, though recovery time varies. Follow-up appointments monitor healing and may include imaging to ensure proper bone alignment. Physical therapy is often recommended to restore strength and mobility.

Complications

• Nonunion or malunion of the fracture.
• Post-traumatic arthritis in the knee joint.
• Chronic pain or stiffness.
• Infection (if surgical intervention is required).

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 medical attention for severe knee pain, inability to bear weight, or visible deformity after an injury.

Tips for Medical Coders

Document the side (right), fracture type (transverse), displacement status, and encounter type (initial for closed fracture). Ensure clinical notes specify the fracture as closed and the encounter as initial to support accurate coding.
