S82.152 Displaced fracture of left tibial tuberosity

Name of the Condition

• Displaced fracture of left tibial tuberosity

Summary

A displaced fracture of the left tibial tuberosity involves a break in the bony prominence on the anterior upper tibia where the patellar tendon attaches. Displacement means the bone fragments are misaligned, which may affect knee function. This injury typically results from trauma or excessive stress on the knee, particularly in active individuals.

Causes

Traumatic injury is the primary cause, such as direct impact to the knee, falls, or sudden forceful contraction of the quadriceps muscle. Sports-related incidents, motor vehicle accidents, or other high-impact events can lead to this fracture.

Risk Factors

• Participation in activities with rapid knee extension or jumping (e.g., basketball, soccer)
• Adolescent growth spurts, especially in athletes
• Previous knee injuries or surgeries
• Osteoporosis or bone-weakening conditions

Symptoms

• Severe pain and swelling over the tibial tuberosity
• Inability to fully extend the knee or bear weight
• Visible deformity or abnormal positioning of the knee
• Bruising or discoloration in the affected area

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and deformity. Imaging studies, such as X-rays, are used to confirm the fracture and evaluate displacement. Additional tests like MRI may be ordered to assess soft tissue damage.

Treatment Options

• Immobilization with a brace or cast to stabilize the fracture
• Pain management with analgesics or anti-inflammatory medications
• Surgical intervention for severe displacement or instability
• Physical therapy to restore strength and mobility

Prognosis and Follow-Up

Prognosis depends on the severity of displacement and treatment adherence. Most patients recover fully with proper care, but delayed healing or residual stiffness may occur. Follow-up imaging and physical therapy are often recommended to monitor progress.

Complications

• Nonunion or malunion of the fracture
• Chronic pain or instability
• Knee stiffness or limited range of motion
• Infection (if surgical intervention is required)

Lifestyle & Prevention

• Use proper protective gear during high-impact sports
• Strengthen quadriceps and surrounding muscles to reduce stress on the knee
• Avoid sudden, forceful movements that strain the knee
• Maintain bone health through adequate nutrition and exercise

When to Seek Professional Help

Seek immediate medical attention if you experience severe knee pain, inability to bear weight, visible deformity, or sudden swelling after an injury. Persistent pain or difficulty moving the knee after initial treatment also warrants evaluation.

Tips for Medical Coders

Document the laterality (left) and displacement status clearly. Ensure clinical notes specify the fracture type and any associated injuries. For accurate coding, confirm the fracture is displaced and not merely a nondisplaced or avulsion injury.
