S82.036A Nondisplaced transverse fracture of unspecified patella, initial encounter for closed fracture

Name of the Condition

• Nondisplaced transverse fracture of unspecified patella, initial encounter for closed fracture

Summary

This condition involves a horizontal break across the kneecap (patella) where the bone fragments remain aligned and the fracture is closed (skin intact). The fracture line runs perpendicular to the bone’s long axis, and the lack of displacement means the bone pieces have not shifted from their normal position. This is an initial encounter, indicating the first time the fracture is being treated.

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. Physical therapy to restore strength and mobility once the fracture stabilizes.
• Surgical intervention: Rarely needed for nondisplaced fractures, but may be considered if the fracture is unstable or fails to heal.

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.
• Post-traumatic arthritis due to joint damage.
• Chronic pain or stiffness in the knee.
• Infection (rare, especially with surgical intervention).

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid falls by improving balance and home safety.
• Gradually return to activity under medical guidance after recovery.

When to Seek Professional Help

Seek immediate care 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 treatment.

Tips for Medical Coders

Document the fracture as nondisplaced and transverse, specify the patella as unspecified, and confirm the encounter is initial and the fracture is closed. Ensure clinical notes support the lack of displacement and closed nature to justify the code.
