Preoperative MRI to plan infrapatellar fat pad resection during total knee arthroplasty

We thank Pan et al for their initial paper1 and subsequent response to our comment.2–4 We agree with the proposed biphasic role of the infrapatellar fat pad (IPFP). Although there is evidence to support a change of practice towards preservation of the IPFP,5 we agree that there should not be a ‘one shoe fits all approach’, there being cases in which benefit may be derived from IPFP resection.

A considered approach offered by Han et al4 involves using screening MRIs to identify IPFP signal intensity alterations and a subsequent indication for resection. However, this technique is not yet validated with high-quality randomised controlled trials (RCTs).4 An alternative solution proposed by Sekiya et al6 may be the use of postarthroplasty arthroscopic IPFP debridement.

Currently the incidence of knee pain post total knee arthroplasty (TKA)...
