Background Measuring HRQOL is simple, inexpensive, permits the health status to be measured over time, and is useful to compare or initiate treatments and evaluate results, facilitating homogenization in patient inclusion. Objectives To evaluate disease‐specific and generic HRQOL and influence of associated factors in patients undergoing open debridement for acute postsurgical knee prosthetic joint infection after TKR at 12 and 48 months after completing antibiotic treatment and considered cured of infection. Methods Health‐related quality‐of‐life measures were administered at baseline ( WOMAC ) and 12 and 48 months ( WOMAC and SF ‐36) in patients with prosthesis retention, no symptoms of infection, and CRP (≤ 1 mg/dL). Results Thirty patients were included, and 24 were evaluated at 48 months. WOMAC scores improved significantly ( P < 0.01) at 12 and 48 months. The effect size was 0.72 for stiffness, 2.01 for pain, and 2.15 for function. At 48 months, improvements were greater ( P < 0.02) except for stiffness. The most frequently isolated microorganisms were Staphylococcus aureus (14 patients) and coagulase‐negative staphylococci (9 patients). SF ‐36 physical role, bodily pain, emotional role, and mental health dimension scores at 12 and 48 months were significantly worse in patients with isolates of Staphylococcus aureus ( P < 0.05). Conclusions Health‐related quality‐of‐life measures detected significant differences in outcomes in patients infected by S. aureus compared with patients infected by other microorganisms. HRQOL measures may provide useful complementary information on outcomes after acute postoperative infection.
