S82.023 Displaced longitudinal fracture of unspecified patella

Name of the Condition

• Displaced longitudinal fracture of unspecified patella

Summary

A displaced longitudinal fracture of the unspecified 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.

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 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

• 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 after the fracture heals.
• Pain Management: Medications or other methods to control discomfort.

Prognosis and Follow-Up

Recovery depends on the severity of the fracture and treatment. Most patients regain full knee function with proper care, but stiffness or weakness may persist. Follow-up appointments monitor healing and adjust treatment as needed.

Complications

• Nonunion or delayed healing of the fracture.
• Arthritis in the knee joint over time.
• Persistent pain or limited mobility.
• Infection, if surgery is performed.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid falls by using assistive devices if needed.
• Warm up and stretch before physical activity.

When to Seek Professional Help

Seek immediate medical attention if you experience severe knee pain, swelling, or inability to bear weight after an injury. Contact a healthcare provider if symptoms worsen or do not improve with initial care.

Tips for Medical Coders

Document the fracture type (displaced, longitudinal) and specify the patella as "unspecified" when laterality is not documented. Ensure clinical notes support the displacement and fracture orientation to justify the code.
