S82.151S Displaced fracture of right tibial tuberosity, sequela

Name of the Condition

• Displaced fracture of right tibial tuberosity, sequela

Summary

A displaced fracture of the right tibial tuberosity, sequela, refers to a residual condition following a previous fracture of the bony prominence on the anterior upper tibia where the patellar tendon attaches. The term "sequela" indicates this is a complication or long-term effect of the initial injury, with persistent misalignment or functional impairment. This condition may result from incomplete healing, malunion, or chronic instability affecting knee mechanics.

Causes

The sequela arises from a prior displaced fracture of the 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, including persistent displacement or functional limitations.

Risk Factors

• History of tibial tuberosity fracture
• Incomplete or delayed fracture healing
• High-impact activities or sports participation
• Underlying bone or connective tissue disorders
• Prior surgical interventions with suboptimal outcomes

Symptoms

• Chronic pain or discomfort localized to the tibial tuberosity
• Reduced knee extension or persistent weakness
• Visible or palpable deformity at the fracture site
• Intermittent swelling or instability during movement
• Difficulty bearing weight or performing high-impact activities

Diagnosis

Diagnosis involves a detailed patient history to confirm prior fracture and a physical examination to assess residual deformity, range of motion, and functional limitations. Imaging studies, such as X-rays or CT scans, are used to evaluate bone alignment and healing status. Functional assessments may be conducted to determine the impact on daily activities or sports performance.

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 to correct persistent displacement. Pain management strategies, such as NSAIDs or corticosteroid injections, may be employed to alleviate discomfort.

Prognosis and Follow-Up

Prognosis depends on the severity of residual displacement and functional impairment. Most patients experience improved symptoms with appropriate management, though some may have persistent limitations. Regular follow-up appointments are recommended to monitor healing, adjust treatment plans, and address any new complications.

Complications

• Chronic pain or instability
• Reduced knee mobility or strength
• Increased risk of re-injury
• Potential need for additional surgery
• Long-term functional limitations affecting daily activities

Lifestyle & Prevention

• Avoid high-impact activities that stress the knee
• Engage in low-impact exercises to maintain strength and flexibility
• Use protective gear during sports or physical activities
• Follow rehabilitation protocols post-injury to optimize healing
• Maintain a healthy weight to reduce joint stress

When to Seek Professional Help

Seek medical attention if symptoms worsen, new pain or swelling develops, or functional limitations interfere with daily activities. Prompt evaluation is necessary if instability, locking, or inability to bear weight occurs, as these may indicate new injury or complications.

Tips for Medical Coders

This code is used for a sequela of a displaced fracture of the right tibial tuberosity. Documentation should specify the residual effects of the prior fracture, including any persistent displacement, functional impairment, or chronic symptoms. Ensure the encounter is linked to the original injury and that the sequela is clearly differentiated from acute or active fracture management.
