Preservation of the infrapatellar fat pad during total knee arthroplasty reduces subacute postoperative anterior knee pain: a randomized controlled trial.

ABSTRACT:

Background

Preservation of the infrapatellar fat pad (IPFP) during total knee arthroplasty (TKA) is associated with a lower incidence of postoperative anterior knee pain (AKP). However, the comparative efficacy of IPFP preservation remains unclear. The objective of this randomized controlled trial (RCT) was to compare the incidence of AKP between IPFP preservation and partial excision of the IPFP.

Methods

This prospective RCT included patients with primary varus gonarthrosis < 20° who underwent unilateral computer-assisted TKA between March 2019 and November 2020. Patients were randomly assigned to the partial excision or preservation groups. The intraoperative and postoperative protocols were the same in each group. The incidence and severity of AKP, range of motion (ROM),
