Fracture of the Femoral Component after Total Knee Arthroplasty Using Anterior-Posterior Glide Mobile-Bearing System / 대한정형외과학회잡지

The authors diagnosed femoral component fracture after total knee arthroplasty (TKA) using an anterior-posterior glide mobile-bearing system in a 78-year-old female patient who visited with severe pain and flexion limitations in the left knee and performed revision TKA. The fracture of the femoral component after TKA is a rare complication, and various factors cause the fracture of the femoral component. This case is reported along with a literature review.

Does the Use of a Silicone Ring Tourniquet Help Reduce Bleeding in the Minimally Invasive Internal Fixation with Locking Plate for Distal Femoral Fractures?

Purpose@#This study evaluated the usefulness of a silicone ring tourniquet by analyzing the changes in the perioperative hemoglobin (Hb) levels or amount of perioperative bleeding compared to those of a pneumatic tourniquet or no usage during minimally invasive plate fixation for distal femoral fractures. @*Materials and Methods@#From January 2017 to December 2019, 30 patients who underwent minimally invasive plate fixation using a locking compression plate for distal femoral fractures were evaluated and classified as a silicone ring tourniquet (Group 1), a pneumatic tourniquet (Group 2), and no usage (Group 3). The variables for analysis were age, sex, preoperative Hb (preHb), postoperative 72-hour Hb (postHb), differences between preHb and postHb (preHb-postHb), amount of intraoperative and overall transfusion, estimated unit of transfusion corrected by preHb-postHb and total transfusion (Hb-lost), amount of intraoperative and postoperative and total bleeding. One-way ANOVA was used to identify the differences between the groups. @*Results@#The age, sex, operation time, preHb, preHb-postHb, amount of intraoperative and overall transfusion and Hb-lost were similar in the two groups. The amount of intraoperative bleeding was significantly lower in Group 1 than Group 3 (p=0.004), but there was no difference in the amount of postoperative and total bleeding between the two groups. @*Conclusion@#The use of a silicone ring tourniquet in the minimally invasive plate fixation for distal femoral fractures decreased the amount of intraoperative bleeding compared to no use of a tourniquet.
