S82.041S Displaced comminuted fracture of right patella, sequela

Name of the Condition

• Displaced comminuted fracture of right patella, sequela

Summary

This condition represents a sequela (late effect) of a previously sustained displaced comminuted fracture of the right patella (kneecap). The fracture involved multiple bone fragments that were displaced from their normal anatomical position. As a sequela, it reflects the residual effects or complications that persist after the initial injury and its treatment phase have concluded.

Causes

The underlying cause is a prior displaced comminuted fracture of the right patella, typically resulting from direct trauma to the knee. This initial injury may have originated from events such as falls, motor vehicle accidents, or high-impact sports injuries, where forceful impact or muscle contraction led to bone fragmentation and displacement.

Risk Factors

• Prior history of knee trauma or fracture.
• Inadequate healing or malunion of the original fracture.
• Osteoporosis or bone-weakening conditions that impair recovery.
• Activities or occupations involving repetitive knee stress.

Symptoms

• Chronic knee pain, particularly with movement or weight-bearing.
• Reduced range of motion in the right knee.
• Persistent swelling or deformity around the kneecap.
• Instability or weakness in the knee joint.
• Possible clicking or grinding sensations (crepitus) during movement.

Diagnosis

Diagnosis relies on clinical evaluation of persistent symptoms and functional limitations. Imaging studies, such as X-rays or CT scans, are used to assess residual bone displacement, malunion, or associated joint damage. The documentation must confirm the condition as a sequela of the original fracture, with no active healing process indicated.

Treatment Options

Management focuses on addressing residual symptoms and functional impairment. Options may include physical therapy to improve strength and mobility, pain management, or surgical intervention for severe malunion or instability. Treatment is tailored to the extent of residual damage and the patient’s functional needs.

Prognosis and Follow-Up

Prognosis depends on the severity of the residual bone and joint damage. Many patients experience improved function with appropriate treatment, though some may have long-term limitations. Regular follow-up is important to monitor for progressive joint degeneration or recurrent instability.

Complications

• Chronic knee pain or arthritis.
• Persistent instability or weakness.
• Limited range of motion.
• Need for additional surgical intervention.

Lifestyle & Prevention

• Engage in low-impact exercises to maintain knee strength without stressing the joint.
• Use supportive footwear and avoid high-impact activities that strain the knee.
• Maintain a healthy weight to reduce joint load.
• Follow post-treatment guidelines to optimize recovery and minimize long-term effects.

When to Seek Professional Help

Seek medical attention if you experience worsening pain, new swelling, or a decrease in knee function. Prompt evaluation is necessary if instability or difficulty bearing weight on the right leg develops, as these may indicate new injury or complications.

Tips for Medical Coders

Document the sequela status clearly, indicating that the condition is a late effect of the original fracture. Ensure that the record specifies the right patella and confirms the fracture as displaced and comminuted. Differentiate this from active treatment phases by verifying the absence of recent injury or healing indicators.
