Bullous Pemphigoid After Total Knee Arthroplasty

Area of Science:

• Orthopedic Surgery
• Dermatology
• Autoimmune Disorders

Background:

• Total knee arthroplasty (TKA) is a common orthopedic procedure with a low complication rate.
• The increasing volume of TKA procedures is anticipated to lead to a rise in rare complications.
• Understanding and managing these uncommon post-operative issues is critical for patient outcomes.

Observation:

• A case of bullous pemphigoid, an autoimmune blistering skin disease, is presented following TKA.
• The patient was otherwise healthy prior to the total knee arthroplasty.
• The complication necessitated hospital readmission.

Findings:

• Bullous pemphigoid is a rare but significant complication that can arise after total knee arthroplasty.
• The autoimmune nature of bullous pemphigoid requires specific dermatological management.
• Prompt identification and intervention are key to managing the condition.

Implications:

• Early diagnosis and treatment of post-TKA bullous pemphigoid can limit disease progression.
• Effective management may prevent secondary complications and improve patient recovery.
• This case highlights the importance of considering rare dermatological conditions in TKA patients presenting with new skin lesions.
