Name of the Condition

• Common Names: Periprosthetic Fracture of the Right Knee
• Medical Term: Periprosthetic fracture around internal prosthetic right knee joint

Summary

A periprosthetic fracture around the right knee is a type of bone fracture that occurs near or around a knee joint prosthetic implant. These fractures typically happen following knee replacement surgery and can be complex due to the presence of the prosthetic.

Causes

• Trauma or accidents, such as falls.
• Mechanical stress or loosening of the prosthetic joint.
• Bone weakening conditions like osteoporosis or infection.

Risk Factors

• Advanced age and decreased bone density.
• History of knee replacement surgery.
• High-impact activities or sports.
• Conditions that weaken bone, such as osteoporosis or rheumatoid arthritis.

Symptoms

• Severe pain around the knee and inability to bear weight.
• Swelling or bruising near the knee joint.
• Deformity or noticeable change in joint alignment.
• Limited mobility and joint instability.

Diagnosis

• Physical examination and careful assessment of medical history.

• Imaging tests, such as X-rays, CT scans, or MRIs, to observe fracture details and prosthetic placement.

  Treatment Options

• Surgery: To fix or replace the fractured bone and ensure the stability of the prosthetic.
• Non-surgical management: In specific scenarios, immobilization and physical therapy may be recommended.
• Rehabilitation: Essential for restoring function and strength post-treatment.

Prognosis and Follow-Up

• Prognosis depends on factors like the severity of the fracture and the patient's overall health.
• Regular follow-ups are crucial to monitor healing and prosthetic function, with possible periodic imaging studies.

Complications

• Nonunion or malunion of the fracture.
• Loosening or failure of the prosthetic joint.
• Infection at the fracture site or around the prosthetic.
• Limited mobility or persistent pain.

Lifestyle & Prevention

• Maintain a healthy weight and diet rich in calcium and vitamin D.
• Regular, low-impact exercise to strengthen muscles and bones.

• Avoid hazardous activities that increase fall risk.

  When to Seek Professional Help

• Sudden onset of severe knee pain or swelling.
• Apparent deformity or instability of the knee joint.
• Any signs of infection, such as fever or increased redness and warmth around the joint.

Tips for Medical Coders

• Verify the encounter type as subsequent, indicated by the seventh character "D" in the ICD code.
• Ensure the correct anatomical site is noted—in this instance, the right knee.
• Be cautious when distinguishing between initial and subsequent encounters for accurate coding.
