S82.121S Displaced fracture of lateral condyle of right tibia, sequela

Name of the Condition

Displaced fracture of lateral condyle of right tibia, sequela

Summary

This condition represents a displaced fracture of the lateral condyle of the right tibia, occurring as a sequela (late effect) of a previous injury. The lateral condyle is a bony prominence on the outer side of the upper tibia that contributes to knee joint stability. The fracture remains displaced, meaning the bone fragments are not in their normal anatomical alignment, and this code is used for encounters related to the residual effects of the original injury.

Causes

This sequela results from a prior traumatic event, such as a fall, sports injury, or motor vehicle accident, that caused the initial displaced fracture of the lateral condyle. The current condition reflects the long-term consequences of that injury, rather than a new acute event.

Risk Factors

• History of high-impact trauma to the knee.
• Inadequate initial treatment or healing of the original fracture.
• Underlying conditions that impair bone healing, such as diabetes or vascular disease.
• Advanced age, which may reduce bone density and healing capacity.

Symptoms

• Chronic pain or discomfort in the lateral knee area.
• Persistent swelling or stiffness.
• Reduced range of motion in the knee joint.
• Difficulty bearing weight or performing daily activities.
• Possible visible deformity or instability of the knee.

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and joint stability. Imaging studies, such as X-rays or CT scans, are used to evaluate the fracture's current state, including displacement and signs of healing or malunion. The healthcare provider will also review the patient's history of the original injury and prior treatments.

Treatment Options

• Pain management with medications like NSAIDs or analgesics.
• Physical therapy to improve strength, flexibility, and function.
• Orthotic devices or braces to support the knee during activity.
• Surgical intervention, if necessary, to realign or stabilize the fracture (e.g., osteotomy or joint replacement in severe cases).
• Assistive devices, such as crutches or walkers, to reduce weight-bearing stress.

Prognosis and Follow-Up

Prognosis depends on the severity of the initial injury, the degree of displacement, and the effectiveness of treatment. Chronic pain, arthritis, or reduced mobility may persist. Regular follow-up with an orthopedic specialist is recommended to monitor joint function and address any complications. Long-term management may focus on symptom control and preserving quality of life.

Complications

• Post-traumatic arthritis in the knee joint.
• Chronic pain or instability.
• Limited range of motion or stiffness.
• Nerve or vascular damage in severe cases.
• Need for additional surgical interventions.

Lifestyle & Prevention

• Engage in low-impact exercises (e.g., swimming, cycling) to maintain joint health.
• Use proper footwear and avoid high-impact activities that stress the knee.
• Maintain a healthy weight to reduce joint load.
• Follow rehabilitation guidelines to optimize healing and function.
• Use protective gear during sports or activities with fall risks.

When to Seek Professional Help

Seek immediate medical attention if you experience:

• Sudden, severe pain or swelling in the knee.
• Inability to bear weight on the affected leg.
• Visible deformity or instability of the knee joint.
• Signs of infection (e.g., redness, warmth, fever) at the injury site.

Tips for Medical Coders

This code (S82.121S) is used for encounters related to the sequela of a displaced fracture of the lateral condyle of the right tibia. Documentation should clearly indicate the residual effects of the original injury, such as chronic pain, deformity, or functional impairment. Ensure the record specifies the affected side (right tibia) and the nature of the sequela to support accurate coding.
