“…Our findings therefore do not support the theory that intraarticular fibrosis and scarring after infrapatellar fat pad removal cause patellar tendon shortening [7,11]. One clinical study reported that patellar tendon shortening occurred in the group of patients whose fat pads were resected but not in the group whose infrapatellar fat pads were preserved during surgery [14]. In the study, TKA in each group was performed by different surgeons, who may have different surgical techniques and resulted in different results.…”

Background The infrapatellar fat pad is one of the structures that obscures exposure in minimally invasive total knee arthroplasty (MIS TKA). Most MIS TKA surgeons (and many surgeons who use other approaches as well) excise the fat pad for better exposure of the knee. There is still controversy about the result of fat pad excision on patella baja, pain, and function. Questions/purposes In the setting of a randomized controlled trial, we sought to determine whether infrapatellar fat pad excision during MIS TKA causes (1) patellar tendon shortening (as measured by patella baja); (2) increased anterior knee pain; (3) decreases in the Knee Society Score or functional subscore; or (4) more patella-related complications.Methods We randomized 90 patients undergoing MIS TKA at one institution into two groups. In one group, 45 patients underwent MIS TKA with complete infrapatellar fat pad excision and in the other group, 45 patients received MIS TKA without infrapatellar fat pad excision. The patella was selectively resurfaced in these patients; there was no difference between the groups in terms of the percentage of patients whose patellae were resurfaced. We measured patellar tendon shortening, knee flexion, anterior knee pain, Knee Society Score (KSS), functional subscore, and patellar complications at preoperative and postoperative periods of 6 weeks, 3 months, 6 months, and 1 year; complete followup data were available on 86% of patients (77 of 90) who were enrolled.

“…The studies included four level one randomised controlled trials (RCTs) [5,12,15,18]; of which one was high quality [5] and three were low quality [12,15,18]. There were three low quality level two studies [11,13,17]. One high quality [14] and two low quality [4,16] level three studies were included.…”

“…A recent study by Lemon et al [13] demonstrated that excision of the infrapatellar fat pad leads to a significant shortening of the patellar tendon after TKA as compared to the knees where the fat pad is preserved. It has been shown that complete infrapatellar fat pad excision can devascularize the patella by interrupting the infrapatellar anastomosis [10] and this might be the cause for that.…”
