The commonest cause of early failure (within 2 years) of cemented total knee replacement is:

• A Periprosthetic joint infection ✓
• B Aseptic loosening
• C Instability
• D Stiffness/arthrofibrosis

Explanation

Registry data consistently show that periprosthetic joint infection is the leading cause of early TKR failure, accounting for approximately 25–30% of revisions within the first 2 years of the index procedure. Aseptic loosening is the predominant cause of late (>5 years) failure. Instability is the second most common early cause in some series but overall infection predominates.
