S82.022A Displaced longitudinal fracture of left patella, initial encounter for closed fracture

Name of the Condition

• Displaced longitudinal fracture of left patella
• Initial encounter for closed fracture

Summary

A displaced longitudinal fracture of the left patella is a break in the kneecap that runs vertically and is not properly aligned. This type of fracture involves the bone fragments shifting out of their normal position, which can affect knee function and stability. The "closed fracture" designation indicates that the skin remains intact, with no open wound or exposure of the fractured bone.

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 motor vehicle accidents or sports injuries are common triggers.

Risk Factors

• Participation in high-risk activities or contact sports.
• Osteoporosis or other conditions that weaken bone strength.
• Advanced age, which may reduce bone density.
• Previous knee injuries or surgeries.

Symptoms

• Severe pain and swelling in the knee.
• Visible deformity or misalignment of the kneecap.
• Inability to straighten or bend the knee fully.
• Bruising or tenderness around the fracture site.

Diagnosis

Physical examination to assess knee alignment and function. Imaging tests, such as X-rays or CT scans, to confirm the fracture and evaluate displacement. MRI may be used to assess soft tissue damage if needed.

Treatment Options

• Surgery: To realign and stabilize the fracture with hardware like screws or wires.
• Immobilization: Use of a brace or cast to keep the knee stationary during healing.
• Physical therapy: To restore strength and mobility once the fracture has healed.

Prognosis and Follow-Up

Most patients recover well with appropriate treatment, though recovery time may vary. Follow-up appointments are necessary to monitor healing and adjust treatment plans as needed. Long-term outcomes depend on the severity of the fracture and adherence to rehabilitation.

Complications

• Nonunion or malunion of the fracture.
• Chronic pain or stiffness in the knee.
• Post-traumatic arthritis.
• Nerve or blood vessel damage in severe cases.

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 medical attention if you experience severe knee pain, swelling, or deformity after an injury. Prompt evaluation is important to prevent complications and ensure proper healing.

Tips for Medical Coders

Document the fracture type (displaced longitudinal), laterality (left), and encounter type (initial) to support accurate coding. Include details about the fracture's alignment and whether it is closed to confirm the correct code assignment.
