Name of the Condition

• Other Mechanical Complication of Internal Right Knee Prosthesis, Sequela
• ICD-10 Code: T84.092S

Summary

This condition refers to persistent issues that arise from a mechanical failure or complication of a knee prosthesis on the right side. This is categorized as a "sequela," meaning the condition is a consequence of a previous injury or treatment with a knee prosthesis.

Causes

• Wear and tear of the prosthetic components.
• Improper alignment or loosening of the prosthetic parts.
• Infection or inflammation leading to mechanical failure over time.

Risk Factors

• Advanced age.
• History of knee replacement surgery.
• High-impact physical activities that strain the knee.
• Obesity or excessive body weight.
• Pre-existing joint issues or previous injuries.

Symptoms

• Persistent pain in the right knee.
• Swelling or redness around the knee joint.
• Limited range of motion or stiffness in the knee.
• Unusual noises such as clicking or grinding in the joint.

Diagnosis

• Physical examination by an orthopedic specialist.
• Imaging studies such as X-rays, MRI, or CT scans.
• Evaluation of the patient's surgical history and physical activity levels.

Treatment Options

• Pain management through medications like NSAIDs.
• Physical therapy to improve mobility and strength.
• Revision surgery to correct or replace faulty prosthetic components.
• Monitoring and managing underlying infections if present.

Prognosis and Follow-Up

• The outcome depends on the severity and cause of the mechanical complication.
• Regular follow-up appointments to assess knee function and prosthesis status.
• A second surgical intervention may prolong the life of the prosthesis and improve mobility.

Complications

• Progressive pain and reduced joint function.
• Increased risk of falls or injury due to instability.
• Potential need for additional surgical interventions.

Lifestyle & Prevention

• Engaging in low-impact exercises that do not overly stress the knee.
• Maintaining a healthy weight to reduce pressure on the joint.
• Following post-operative care instructions to minimize risk of complications.

When to Seek Professional Help

• Intensifying knee pain or discomfort.
• Noticeable changes in the knee's function or alignment.
• Signs of infection such as fever or severe swelling.

Tips for Medical Coders

• Ensure to capture that the condition is associated with a sequela (complication as a result of a past injury or surgery).
• Verify the side of the body affected to ensure correct coding (Right Knee).
• Double-check patient's medical history for previous surgeries to support coding the sequela condition.
