Retention of the infrapatellar fat pad does not influence the outcome of total knee arthroplasty: a systematic review

At a mean duration of 18.4 ± 6.6 months of follow-up, no difference was found in ROM, patellar height, PROMs, and the rate of pain in the anterior aspect of the knee. The outcomes of TKA are not influenced by IPFP retention or excision. Based on the available scientific literature, surgeons could retain the IPFP if suitable visibility and exposure are possible, but resect it if necessary to facilitate exposure during TKA. Further high-level randomized controlled trials with sustained follow-up periods are required to prove the superiority of one surgical technique over the other.
