S82.034 Nondisplaced transverse fracture of right patella

Name of the Condition

• Nondisplaced transverse fracture of right patella

Summary

This condition involves a horizontal break across the right 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 means the fracture does not disrupt joint stability, though the injury still requires appropriate care.

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 right 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 line is unstable or if other knee structures are involved.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with conservative treatment, though recovery may take several weeks. Follow-up appointments monitor healing and functional recovery. Physical therapy is often recommended to regain full knee function.

Complications

• Delayed healing or nonunion.
• Post-traumatic arthritis.
• Persistent pain or stiffness.
• Rarely, infection or nerve damage.

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 properly before physical activity.

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 type (transverse), displacement status (nondisplaced), and laterality (right) clearly in the medical record. Ensure the diagnosis aligns with clinical findings and imaging results to support accurate coding.
