Introduction: If revision of a unicompartmental knee arthroplasty (UKA) is required, converting it to a total knee arthroplasty (TKA) remains the favored approach. However, worse functional outcomes after revision from UKA to TKA are reported compared to primary TKAs. One potential driver may be a decline in patella height, limiting knee flexion, and increasing patellofemoral stress.

Background: Surgical techniques in two-stage revision total knee arthroplasty (rTKA) include the use of articulating spacers and static spacers. Shortening of the patellar tendon could be a reason for inferior functional outcomes in two-stage septic rTKA . The aim of this study was to determine if articulating spacers also have negative effects on the extensor mechanism in rTKA.

Article Synopsis
- The study aimed to identify patient-specific factors that increase the likelihood of needing a blood transfusion after total hip arthroplasty (THA), where transfusions have become rare.
- Researchers analyzed 2,892 elective THA patients and assessed various factors like age, BMI, ASA grade, sex, and preoperative hemoglobin levels to determine their impact on transfusion risk.
- The results indicated that being over 73 years old, having a hemoglobin level below 7.6 mmol/l, and a BMI of 35.4 kg/m² or higher were significant predictors of needing a transfusion, allowing for preventive strategies to be implemented based on these factors.
