Risk analyses for perioperative morbidities after aseptic knee revision arthroplasty

Area of Science:

• Orthopedic Surgery
• Arthroplasty Research
• Clinical Investigation

Background:

• Total lower limb arthroplasties are increasing, leading to a rise in revision surgeries and healthcare costs.
• Aseptic revision knee arthroplasty is a common but complex orthopedic procedure.
• Understanding morbidities associated with revision knee arthroplasty is crucial for improving patient outcomes.

Purpose of the Study:

• To analyze morbidities following aseptic revision knee arthroplasty.
• To identify factors influencing complications and outcomes in revision knee surgery.
• To evaluate the impact of age and gender on perioperative outcomes.

Main Methods:

• Retrospective analysis of 122 patients undergoing aseptic revision total knee arthroplasty (TKA).
• Collection of data on systemic and surgical complications, blood transfusions, and hemoglobin (Hb) and C-reactive protein (CRP) levels.
• Preoperative and postoperative measurements of Hb and CRP, with statistical analysis using IBM SPSS version 29.

Main Results:

• Significant differences in complication rates were noted based on age and gender.
• Femoral and tibial loosening were more prevalent in patients over 75 years old and with longer intervals since the primary surgery.
• Elevated CRP levels correlated with increased systemic complications, longer hospital stays, and extended operative times.

Conclusions:

• Aseptic knee revision arthroplasty involves significant perioperative risks.
• Age and gender are critical factors influencing complication management and patient outcomes.
• Individualized preoperative strategies are essential for elderly patients, especially those over 75, to mitigate risks like aseptic loosening and enhance recovery.
