Dynamic changes of the infrapatellar fat pad during knee flexion before andafter Total Knee Arthroplasty

Abstract

In this study, we measured the dynamics of the infrapatellar fat pad (IFP) associated with knee joint flexionin the postoperative period after total knee arthroplasty (TKA) using ultrasonography over the preoperative topostoperative period. We then investigated at what time point the dynamic decline of the IFP began to occur.The results suggest that the dynamics of the IFP had already decreased at one month postoperatively. Theresults also suggest that for postoperative TKA patients, intervention for the subpatellar fat body should beperformed within the first postoperative month, when the dynamic decline of the IFP begins to occur.
