Robotic arthroplasty is increasing in acceptance on a global scale as a result of advancements in orthopedic surgery technology.

The investigators aimed to share our anesthesia management experience as well as compare robotic unilateral total knee arthroplasty with conventional surgical technique in this retrospective study.

This study was approved by the ethics committee of a tertiary academic hospital.

The following criteria were used to assess inclusion: ASA physical status I-III patients aged 40-85 years, elective unilateral total knee arthroplasty (TKAs) performed by a single senior orthopedic surgeon and orthopedic team under combined spinal epidural anesthesia (CSEA) between January 2021 and January 2023. Exclusion criteria included urgent surgery, bilateral surgery, previous surgery, missing data, and being lost to follow-up during the perioperative period. Data was collected from the hospital's electronic database records, patient files, and anesthesia charts.

Inclusion Criteria:

• American Society of Anesthesiologists (ASA) physical status I-III
• Between 40-85 years
• Elective unilateral TKAs which were performed by a single senior orthopedic surgeon
• Between January 2021 and January 2023 under CSEA.

Exclusion Criteria:

• Urgent surgery
• Bilateral surgery
• Previous surgery
• Missing data and lost to follow-up in the perioperative period

Patients with American Society of Anesthesiologists (ASA) physical status I-III and elective unilateral TKAs between the ages of 40 and 85 will be analyzed.
