S82.034S Nondisplaced transverse fracture of right patella, sequela

Name of the Condition

• Nondisplaced transverse fracture of right patella, sequela

Summary

This condition represents a horizontal break across the right kneecap (patella) where the bone fragments remain aligned (nondisplaced), and the term "sequela" indicates this is a residual effect or complication following the initial injury. The fracture line runs perpendicular to the bone’s long axis, and the sequela phase implies the fracture has healed or is in a chronic state with ongoing consequences.

Causes

The sequela arises from a prior nondisplaced transverse fracture of the right patella, typically resulting from 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 for the initial fracture.

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.
• Inadequate initial treatment or healing of the original fracture.

Symptoms

• Chronic pain or discomfort in the right knee.
• Residual swelling or stiffness around the kneecap.
• Reduced range of motion or difficulty bearing weight.
• Possible visible deformity or instability in the knee joint.
• Sensation of weakness or "giving way" in the knee.

Diagnosis

A physical examination to assess knee movement, swelling, and tenderness. Imaging studies, typically X-rays, to evaluate bone alignment and healing. Additional tests, such as MRI or CT scans, may be used to assess soft tissue damage or residual complications.

Treatment Options

• Physical therapy to restore strength and mobility.
• Pain management with medications or injections.
• Orthopedic devices, such as braces or supports, to stabilize the knee.
• Surgical intervention if residual instability or deformity is present.
• Lifestyle modifications to avoid activities that exacerbate symptoms.

Prognosis and Follow-Up

Prognosis depends on the severity of the sequela and adherence to treatment. Most patients experience improved function with therapy, but some may have long-term limitations. Regular follow-up appointments monitor healing and adjust treatment plans as needed.

Complications

• Chronic pain or arthritis in the knee joint.
• Reduced mobility or persistent stiffness.
• Instability or recurrent injury.
• Nerve or blood vessel damage in severe cases.
• Delayed union or nonunion of the original fracture.

Lifestyle & Prevention

• Engage in low-impact exercises to maintain knee strength.
• Use protective gear during high-risk activities.
• Maintain a healthy diet rich in calcium and vitamin D to support bone health.
• Avoid sudden, forceful movements that strain the knee.
• Follow post-injury rehabilitation guidelines to prevent sequela.

When to Seek Professional Help

Seek immediate medical attention if symptoms worsen, such as increased pain, swelling, or inability to bear weight. Consult a healthcare provider for persistent discomfort or if new symptoms, like numbness or discoloration, develop.

Tips for Medical Coders

Document the sequela phase clearly, noting the history of the original fracture and any residual effects. Ensure the code S82.034S is used only when the condition is a direct result of a prior fracture and not an active injury. Include details about the nature of the sequela (e.g., chronic pain, instability) to support accurate coding.
