S82.152S Displaced fracture of left tibial tuberosity, sequela

Name of the Condition

• Displaced fracture of left tibial tuberosity, sequela

Summary

A displaced fracture of the left tibial tuberosity, sequela, refers to the residual effects of a previously fractured bony prominence on the anterior upper tibia where the patellar tendon attaches. Sequela indicates the condition is a complication or long-term consequence of the initial injury, with persistent misalignment or functional impairment. This may result from incomplete healing, malunion, or chronic instability affecting knee function.

Causes

The sequela arises from a prior displaced fracture of the left tibial tuberosity, typically caused by trauma such as direct impact, falls, or forceful quadriceps contraction. Inadequate initial treatment, delayed healing, or biological factors (e.g., poor bone quality) can contribute to the development of long-term complications like malunion or chronic pain.

Risk Factors

• Prior history of tibial tuberosity fracture
• Incomplete or delayed fracture healing
• High-impact activities or sports participation
• Underlying bone conditions (e.g., osteoporosis)
• Inadequate rehabilitation or immobilization

Symptoms

• Chronic pain or discomfort over the tibial tuberosity
• Persistent swelling or deformity
• Limited knee extension or instability
• Difficulty bearing weight or performing daily activities
• Possible clicking or catching sensations in the knee

Diagnosis

Diagnosis involves a clinical evaluation of persistent symptoms and prior fracture history. Imaging studies, such as X-rays or CT scans, assess bone alignment and healing. Functional assessments may evaluate knee range of motion and stability. Comparison with prior imaging helps confirm the sequela and rule out new injuries.

Treatment Options

Treatment focuses on managing symptoms and improving function. Options may include physical therapy to strengthen surrounding muscles, orthotic devices for support, or surgical intervention (e.g., osteotomy) to correct malunion. Pain management and activity modification are often part of the plan.

Prognosis and Follow-Up

Prognosis depends on the severity of the sequela and response to treatment. Most patients experience improved function with therapy, though some may have residual limitations. Regular follow-up with imaging and clinical assessments monitors healing and adjusts management as needed.

Complications

• Chronic pain or arthritis
• Persistent knee instability
• Limited mobility or functional impairment
• Need for additional surgical intervention
• Psychological impact from long-term disability

Lifestyle & Prevention

• Avoid high-impact activities that stress the knee
• Maintain a healthy weight to reduce joint load
• Engage in low-impact exercises (e.g., swimming) to preserve mobility
• Use proper protective gear during sports
• Follow rehabilitation protocols post-injury to minimize sequela risk

When to Seek Professional Help

Seek care if symptoms worsen, new pain or swelling occurs, or functional limitations impact daily life. Prompt evaluation is necessary for sudden changes in knee stability or signs of infection (e.g., redness, fever).

Tips for Medical Coders

Document the sequela clearly, noting the prior fracture and its residual effects. Ensure clinical details support the sequela diagnosis, including duration and impact on function. Verify that the code aligns with the patient’s current condition and prior fracture history.
