S82.15 Fracture of tibial tuberosity

Name of the Condition

• Fracture of tibial tuberosity

Summary

A fracture of the tibial tuberosity involves a break in the bony prominence on the anterior tibia where the patellar tendon attaches. This area is critical for knee extension and stability. The fracture may be partial or complete, and displacement can affect tendon function.

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, particularly in adolescents, are common triggers.

Risk Factors

• Participation in high-impact sports (e.g., basketball, soccer)
• Adolescent growth spurts with rapid bone growth
• Previous knee injuries or tendon abnormalities
• Activities involving sudden stops or jumps

Symptoms

• Localized pain and swelling over the tibial tuberosity
• Difficulty extending the knee or bearing weight
• Visible deformity or prominence at the fracture site
• Bruising or tenderness on palpation

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and functional limitations. Imaging studies, such as X-rays, are used to confirm the fracture and evaluate displacement. CT or MRI may be ordered for complex cases.

Treatment Options

• Immobilization with a brace or cast to stabilize the fracture
• Pain management with analgesics or anti-inflammatory medications
• Physical therapy to restore range of motion and strength
• Surgical intervention for displaced or unstable fractures

Prognosis and Follow-Up

Most fractures heal with conservative treatment, but recovery may take several weeks. Follow-up imaging ensures proper healing. Return to activity is gradual, guided by pain and functional recovery.

Complications

• Nonunion or delayed healing
• Chronic pain or instability
• Recurrent fractures
• Tendon or ligament damage

Lifestyle & Prevention

• Warm up and stretch before physical activity
• Use proper technique in sports to avoid sudden stress
• Wear protective gear during high-risk activities
• Maintain bone health with adequate nutrition and exercise

When to Seek Professional Help

Seek care if pain is severe, swelling worsens, or weight-bearing is impossible. Immediate evaluation is needed for open fractures or signs of neurovascular compromise.

Tips for Medical Coders

Document the fracture type (e.g., displaced, nondisplaced), laterality, and encounter details (initial, subsequent, or sequela). Include clinical notes on imaging findings and treatment to support code specificity.
