Abstract
BACKGROUND The fat repositioning technique has been widely used for the treatment of tear trough deformity, and there is a strong belief that excess fat herniation is a prerequisite for the procedure. The purpose of this study was to evaluate its effect in patients with minimal or no excess fat herniation. METHODS A total of 232 patients underwent the procedure and met the inclusion criteria. Of them, 198 were primary cases, and 34 had a hisory of fat removal for blepharoplasty. The amount of infraorbital fat was evaluated preoperatively by palpation. Release of the tear trough ligament and fat redistribution were sequentially performed as described previously. Surgical outcome was assessed based on the Hirmand grading system and the FACE-Q scales. RESULTS Tear trough deformities were eliminated in more than 85% of cases. Aesthetic results were comparable between the primary and secondary surgery groups. The percentage of patients who complained of extremely or moderately severe tear trough deformities decreased from 86.3% preoperatively to 34.0% postoperatively. The scores of the lower eyelid FACE-Q decreased significantly ( P < 0.05). Patients were satisfied with their decision to undergo blepharoplasty (78.2 ± 18.7). Undercorrection of the tear trough occurred in 30 patients. Other complications included 12 cases of transient conjunctiva bleeding, two cases of eyelid numbness, and six cases of dry eye. These resolved spontaneously. CONCLUSION Fat repositioning is a feasible and effective technique for the treatment of tear trough deformities in patients with minimal or no excess orbital fat herniation, provided that a fat pad is palpable. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

Abstract
BACKGROUND This study aimed to evaluate the use of fat grafting enriched with platelet-rich plasma through a computerized-assisted mapping for esthetic restoration in progressive hemifacial atrophy (Parry-Romberg disease). METHODS This prospective study was conducted on 53 patients presented by Parry-Romberg disease and was corrected by facial fat grafting (FFG) enriched with platelet-rich plasma (PRP). A computerized software program was used to design a detailed map to achieve clinical symmetry with fat grafting application, as the anatomical subunits direct 3-dimensional volumetric symmetric, and compartments direct isolated recipient-specific grafting. Also, volumetric asymmetry was assessed through outlines of facial contour, projection, and proportions for both sides and comparing the mirror image of unaffected side as a template. RESULTS Objective ultrasound and photogrammetric measurements showed a significant improvement in facial symmetry postoperatively compared to preoperative (P < 0.05), with no significant differences between 12 and 18 months after surgery. The FACE-Q score regarding comparison before surgery and 18 months after surgery showed a statistically significant improvement in all modules (P < 0.001) with overall satisfaction concerning outcome of 82.7 ± 0.8. CONCLUSION Enriched fat grafting with platelet-rich plasma (PRP) is a good alternative to reconstruct soft tissue defects for patients with progressive hemifacial atrophy (Parry-Romberg disease) with a minimally invasive approach and low complications. It provides volumetric replacement, enhancement of skin texture, and improvement of hyperpigmentation with restoration of facial contour for an esthetic pleasing appearance. Isolated replacement in accordance with the anatomical facial subunits and fat compartments allows three-dimensional reconstruction and maximizes fat retention.

Abstract
PURPOSE Oral submucous fibrosis (OSMF) is a chronic, potentially malignant condition affecting any part of the oral cavity and is prevalent in Southeast Asia and the Indian subcontinent. The aim of this study is to compare the efficacy of buccal fat pad flap with the nasolabial flap in the management of OSMF. METHODS We systematically compared two commonly used constructive techniques in the management of OSMF: the buccal pad of fat flap and the nasolabial flap. We performed a comprehensive search in four databases for all articles published between 1982 and November 2021. We assessed the risk of bias using the Cochrane Handbook and Newcastle-Ottawa Scale. We used the mean difference (MD) for pooling the data with 95% confidence intervals (CIs) and evaluated the heterogeneity between pooled studies using χ2 and I2 tests. RESULTS Out of 917 studies, six were included in this review. The meta-analysis significantly favored conventional nasolabial flap over buccal fat pad flap in improving the maximal mouth opening (MD, - 2.52; 95% CI, - 4.44 to - 0.60; P = 0.01; I2 = 0%) after OSMF reconstructive surgery. Conversely, when it comes to esthetic outcomes, these studies favored buccal fat pad flap. CONCLUSION Our meta-analysis found that nasolabial flap was better than buccal fat pad flap in terms of mouth opening restoration after OSMF reconstructive surgery. Also, the included studies found better results, favoring nasolabial flap over buccal fat pad flap in terms of oral commissural width restoration. Also, these studies reported better outcomes in terms of esthetics, favoring buccal fat pad flap. Further studies with larger sample sizes and different populations/races are needed to confirm our findings.

Abstract
In the past 5 years, aesthetic surgery of the buttock has changed a lot with the use of technologies like imaging ultrasound to get safer and more beautiful results. These techniques are not only used to make a safer fat infiltration in the buttock, but also for modeling it. The aim of this study was to describe ultrasound-guided subiliac crest deep fat liposuction for contouring the buttock-back region. This area is often overlooked in gluteal frame management because of the depth at which it is located. Healthy patients were chosen for whom this deep back ultrasound technique was performed to improve the gluteal frame. The technique involved making a small incision in the iliac crest of the ilium, followed by identification of the area of deep posterior fat below the iliac crest under ultrasonographic control. A cannula was positioned to deliver static tumescent infiltration and liposuction was performed. This study included 16 female patients aged 20 to 45 years old who underwent this procedure. The area was infiltrated with 150 to 200 mL of tumescent solution per side, and 175 to 200 mL of fat was obtained. The depth of the study area varied but was observed to be generally located between 3 and 5 cm from the skin. This study indicates that this technique is safe and effective in achieving aspiration of the subiliac crest deep fat, which enhances the frame for buttock-back contouring. Ultrasound was indispensable for locating the fat and infiltrating the area for subsequent liposuction.See the abstract translated into Hindi, Portuguese, Korean, German, Italian, Arabic, Chinese, and Taiwanese online here: https://doi.org/10.1093/asj/sjad236.

Abstract
The role of buccal fat pad (BFP) as interpositional material in the temporomandibular joint ankylosis (TMJA) have been well documented. The purpose of the present systematic review is to reinforce the role of buccal fat pad as interpositional material in preventing re-ankylosis. A systematic search was conducted in PubMed, Google Scholar, Semantic scholar and Cochrane library database from 1980 to 2022 following the PRISMA guidelines. The studies using BFP as interpositional material in TMJA with more than 10 patients with atleast a follow-up of 6-months were included. All the human studies {prospective, retrospective, case reports/series (with more than 10 subjects), randomized or non-randomized trial) reporting the outcome of BFP as interpositional material were included. The present systematic review included 11 studies (prospective=7, Retrospective=3 and ambispective=1) using BFP as interpositional material. The total number of patients were 205. The number of unilateral TMJA and bilateral TMJA were 153 and 52 respectively, making a number of joint to 257. The distribution of gender was almost equal (few studies did not report the gender distribution). The minimum follow-up was 6-months and extended up to 5.3 years. Out of 205 patients, no re-ankylosis was reported in patients. The authors concluded that the BFP is nearly ideal and a preferred interpositional material to prevent re-ankylosis in temporomandibular joint ankylosis. Its vicinity to TMJ, ease of harvesting through the same surgical site and avoiding other scar makes it a preferred interpositional material in TMJA cases.

Abstract
BACKGROUND Much debate exists within the current literature as to which plane is safest and most effective for gluteal implant buttock augmentation. A novel subfascial/intramuscular (SF/IM) dual-plane technique appears to combine the benefits of each plane. OBJECTIVES The aim of this study was to describe our experience with SF/IM plane gluteal implantation, and to discuss its indications, efficacy, and safety, and offer recommendations on its proper use. METHODS A retrospective chart review was conducted of 175 consecutive cases of gluteal augmentation with solid silicone implants in the SF/IM pocket, with and without supplemental autologous fat transfer. Outcomes from all patients were analyzed to determine the rate of complication and need for surgical revision. RESULTS In 175 cases of bilateral buttock augmentation with gluteal implantation using the SF/IM pocket, the most common complication was infection. This complication was seen in 13 cases (7.43%), 7 (4%) of which were superficial and did not require surgical intervention. Other complications included dehiscence, seroma, capsular contracture, and implant migration. CONCLUSIONS The SF/IM gluteal implantation, in combination with liposculpture and autologous fat transfer into the overlaying subcutaneous space, allows for a durable cosmetic augmentation of the buttocks in patients lacking sufficient volume for augmentation with fat transfer alone. This technique was found to have complication rates similar to those of other established augmentation techniques, as well the cosmetic advantages of a large, stable pocket with thick, soft tissue coverage of the inferior pole.

Abstract
Age-related changes in the lower eyelid are noticed by patients as bags or circles under the eye, a tired look, and a flattened face. Lower eyelid blepharoplasty, in which the excess skin and/or orbital fat is excised and repositioned, is mainly performed for aesthetic reasons rather than the correction of functional abnormalities. Favorable outcomes for the combination of these approaches have been reported, but the most suitable surgical technique is still debated. This systematic narrative review deals with the indications, preoperative considerations, operative techniques, and complications of several different surgical approaches to lower eyelid blepharoplasty.

Abstract
BACKGROUND The tuberous breast is considered a breast deformity characterized by varying degrees of herniation of the parenchyma, widened nipple-areolar complex (NAC), absence of the lower quadrants, and may involve several degrees of hypoplasia and asymmetry causing significant psychosocial distress. OBJECTIVES The paper aimed to compare the results obtained in patients suffering tuberous breast treated with fat grafting (FG), with those of patients treated with a mastopexy and silicone implants (M-SI) also analyzing the influence of breast and chest deformities (degrees of hypoplasia and tuberous breast, volume and NAC asymmetry, pectus excavatum, and carinatum) in the reconstructive outcomes. METHODS A retrospective, case-control study was conducted. Thirty-five patients affected by tuberous breast with several degrees of hypoplasia and asymmetry were treated with FG, comparing results with those of 30 patients treated with M-SI. Postoperative follow-up took place at 1, 3, 7, 12, 24, 48, weeks, and then annually for 2 years. RESULTS 77% (n = 27) of patients treated with two FG procedures showed excellent results after 1 year compared with the patients treated with only one M-SI procedure, who showed the same results in 73% (n = 22) of cases, but the naturalness and the satisfaction degree in the FG group were higher than that in the M-SI group (p < .0001 vs. M-SI group). CONCLUSIONS Patients treated with FG showed natural breasts without scars and excellent cosmetic results after two procedures. Patients treated with M-SI showed more evident and lasting results after only one procedure, presenting though scars and less natural results.

Abstract
BACKGROUND Fat manipulation procedures such as liposuction contain a degree of subjectivity primarily guided by the surgeon's visual or tactile perception of the underlying fat. Currently, there is no cost-effective, direct method to objectively measure fat depth and volume in real time. OBJECTIVES Utilizing innovative ultrasound-based software, the authors aimed to validate fat tissue volume and distribution measurements in the preoperative setting. METHODS Eighteen participants were recruited to evaluate the accuracy of the new software. Recruited participants underwent ultrasound scans within the preoperative markings of the study area before surgery. Ultrasound-estimated fat profiles were generated with the in-house software and compared directly with the intraoperative aspirated fat recorded after gravity separation. RESULTS Participants' mean age and BMI were 47.6 (11.3) years and 25.6 (2.3) kg/m2, respectively. Evaluation of trial data showed promising results following the use of a Bland Altman agreement analysis. For the 18 patients and 44 volumes estimated, 43 of 44 measurements fell within a confidence interval of 95% when compared with the clinical lipoaspirate (dry) volumes collected postsurgery. The bias was estimated at 9.15 mL with a standard deviation of 17.08 mL and 95% confidence interval between -24.34 mL and 42.63 mL. CONCLUSIONS Preoperative fat assessment measurements agreed significantly with intraoperative lipoaspirate volumes. The pilot study demonstrates, for the first time, a novel companion tool with the prospect of supporting surgeons in surgical planning, measuring, and executing the transfer of adipose tissues.

Abstract
BACKGROUND A limitation of current facelift techniques is the early postoperative reappearance of anterior midcheek laxity associated with recurrence of the nasolabial fold (NLF). OBJECTIVES This study was undertaken to examine the regional anatomy of the anterior midcheek and NLF with a focus on explaining the early recurrence phenomenon and to explore the possibility of alternative surgical methods that prolong NLF correction. METHODS Fifty cadaver heads were studied (16 embalmed, 34 fresh; mean age, 75 years). Following preliminary dissections and macrosectioning, a series of standardized layered dissections were performed, complemented by histology, sheet plastination, and microcomputed tomography. Mechanical testing of the melo fat pad (MFP) and skin was performed to gain insight on which structure is responsible for transmission of the lifting tension in a composite facelift procedure. RESULTS Anatomic dissections, sheet plastination, and microcomputed tomography demonstrated the 3-dimensional architecture and borders of the MFP. Histology of a lifted midcheek demonstrated that a composite MFP lift causes a change in connective tissue organization from a hanging-down pattern into a pulled-upward pattern, suggesting traction on the skin. Mechanical testing confirmed that, in a composite lift, despite the sutures being placed directly into the deep aspect of the MFP, the lifting tension distal to the suture is transmitted through the skin and not through the MFP. CONCLUSIONS The usual method of performing a composite midcheek lift results in the skin, and not the MFP itself, bearing the load of the nondissected tissues distal to the lifting suture. For this reason, early recurrence of the NLF occurs following skin relaxation in the postoperative period. Accordingly, specific surgical procedures for remodeling the MFP should be explored, possibly in combination with volume restoration of the fat and bone, for more lasting improvement of the NLF.

Abstract
We read with great interest the article titled "Tuberous breast, deformities, and asymmetries: a retrospective analysis comparing fat grafting versus mastopexy and breast implants" by Gentile. In this interesting paper, the author compares results obtained in patients suffering from tuberous breast, deformities, and asymmetries treated with fat grafting (FG) with those of patients who underwent mastopexy and breast implant (M-SI). The TB reconstructive procedures aims to release the constricted base both vertically and horizontally, restore the correct nipple-inframammary fold distance, avoid the double bubble, correct ptosis and hypertrophy, and restore both volume and asymmetry. In most cases, it poses a real challenge to surgical correction through the exclusive use of only one of the surgical techniques described in the paper. We think the type of surgical procedure is determined by specific factors which must be considered by both the surgeon and the patient. We propose a classification that analyzes 3 characteristics (type of stenosis, hypoplasia, and ptosis) and identifies 8 classes of TB: this classification allows to guide the surgeon in choosing the most appropriate surgical maneuvers for each type of TB. In conclusion, we think that each case of TB, deformities, and asymmetries should be carefully studied and classified, opting for the most appropriate surgical method "tailored made" to ensure the best result for the patient. Among these techniques, M-SI and FG are two important weapons in the hands of the surgeon, who must use them wisely, knowing each indication and limits.Level of Evidence V This journal requires that authors assign a level of evidence to each article.

Abstract
PURPOSE To review and summarize studies on the anatomy and involutional changes of the midface. METHODS A PubMed search was performed searching for studies on the anatomy and involutional changes concerning the midface. RESULTS The anatomy of the midface is complex. Studies of involutional change vary in scientific quality and have conflicting results. However, it appears that among the more common changes, there is a decrease in the maxillary and pyriform angle, with changes to the orbital floor position. Further, there appears to be an inferior migration of the fat compartments of the midface during aging, exacerbating the hollow of the palpebromalar groove and causing a deepening of the nasojugal groove. Changes to the volume of the buccal extension of the buccal fat pad exacerbate these changes and contribute to the gestalt changes associated with facial aging. Here, we review the major characteristics of soft tissue and bony changes on the midface, with special reference to their anatomic relationships. CONCLUSIONS The major findings characterizing midface aging are related largely to the soft tissue. However, more robust studies are required to quantify these changes and to appraise their impact on the overall manifestation of aging.

Abstract
BACKGROUND AND OBJECTIVE Obesity may increase the risk of adverse events after total knee arthroplasty (TKA). Although body mass index (BMI) is commonly used in categorizing obesity, its accuracy is limited. Body fat percentage (BFP) might indicate adiposity status and predict arthroplasty-related outcomes better than BMI. We investigated whether BFP is predictive of TKA-related outcomes. METHODS In this secondary analysis, BFP was measured preoperatively from 294 participants of a randomized trial that investigated the effects of tourniquet and anesthesia methods on TKA. Data concerning in-hospital assessments and events were collected. Knee range of motion (ROM) was measured, the Brief Pain Inventory-short form and Oxford Knee Score questionnaires were used to collect data on patient-reported pain and function, and the 15-dimensional health-related questionnaire was used to assess quality of life preoperatively and 3 and 12 months postoperatively. The patients reported satisfaction to TKA 3 and 12 months postoperatively. Data concerning infectious and thromboembolic events within 90 postoperative days and revision surgery, manipulation under anesthesia, and mortality within 1 year were collected. A separate post hoc analysis was performed for 399 participants to assess the effects of BMI on the respective outcomes. RESULTS A 1-unit increase in BFP affected the ROM by -0.37° (95% confidence interval (CI) = -0.60 to -0.13) 12 months after surgery. BFP was not significantly associated with the operation time or adverse events. However, the number of most adverse events remained too low for adjusted analysis. A 1-unit increase in BMI increased the operation time by 0.57 min (95% CI = 0.10 to 1.04) and affected the ROM by -0.47° (95% CI = -0.74 to -0.20) 12 months postoperatively. Neither BFP nor BMI was significantly associated with acute pain, pain management, length of stay, or with pain, function, quality of life, or satisfaction to TKA at 12 months after surgery. CONCLUSIONS BFP seems to be a poor predictor of in-hospital results and of patient-reported outcomes 1 year after TKA. TWITTER HANDLE In this secondary analysis of a randomized trial, body fat percentage was poorly predictive of clinical outcomes during hospital stay and of patient-reported outcomes 1 year after TKA.

Abstract
CASE We present a fifteen-year-old adolescent boy with anterior knee pain and a palpable tender swelling in the suprapatellar region with painful terminal extension. Imaging was suggestive of a vascular lesion in the suprapatellar fat pad. He underwent arthroscopic debridement and postoperatively regained his terminal extension. CONCLUSION Suprapatellar fat pad impingement can rarely be due to vascular lesions or lipomatous tumors affecting the suprapatellar fat pad. If conservative treatment is unsuccessful, surgery can provide good pain relief. The tissue excised should always be sent for histopathological examination.

Abstract
OBJECTIVE This case-control study aimed to analyze the dynamics of macrophage infiltration in subcutaneous adipose tissue following bariatric surgery or conservative treatment of obesity and to clarify whether these features predict the weight loss outcome after the surgery. METHODS Subcutaneous tissue samples taken before and 12 months after laparoscopic Roux-en-Y gastric bypass surgery (n = 39) or conservative (n = 43) treatment for obesity were analyzed. Fat cell size was determined, and with CD68 immunohistochemistry, crown-like structures (CLS) were counted and single macrophages were quantitated. RESULTS A major decline in CLS density from 4.1 (SD 3.5) to 1.1 (SD 0.8) per 1000 fat cells (p < 0.000) was found, regardless of the degree of weight loss after the surgery. Surgery had no effect on the fraction of infiltrating single-cell macrophages in subcutaneous adipose tissue. The abundance of these macrophage populations before the intervention did not predict the degree of postsurgery weight loss or suboptimal response to the surgery. CONCLUSIONS The effect of gastric bypass on adipose tissue inflammatory status associates closely with CLS density even in subjects with suboptimal weight loss. The study suggests that factors related to bypass surgery other than weight loss modify the inflammatory response in adipose tissue.

Abstract
Bariatric surgery has been recognized as the safest and most effective procedure for controlling type 2 diabetes (T2D) and obesity in carefully selected patients. The aim of the present study was to compare the effects of Sleeve Gastrectomy (SG) and Single Anastomosis Duodenoileal Bypass with SG (SADI-S) on the metabolic profile of diet-induced obese rats. A total of 35 four-week-old male Wistar rats were submitted to surgical interventions (sham operation, SG and SADI-S) after 4 months of being fed a high-fat diet. Body weight, metabolic profile and the expression of molecules involved in the control of subcutaneous white (SCWAT), brown (BAT) and beige (BeAT) adipose tissue function were analyzed. SADI-S surgery was associated with significantly decreased amounts of total fat pads (p < 0.001) as well as better control of lipid and glucose metabolism compared to the SG counterparts. An improved expression of molecules involved in fat browning in SCWAT and in the control of BAT and BeAT differentiation and function was observed following SADI-S. Together, our findings provide evidence that the enhanced metabolic improvement and their continued durability after SADI-S compared to SG rely, at least in part, on the improvement of the BeAT phenotype and function.

Abstract
PURPOSE To morphologically describe and mathematically quantify a novel clinical feature of thyroid eye disease (TED). METHODS A retrospective study was conducted of TED patients and age-sex-matched normal controls. The arched Rainbow Brow appearance in TED patients was determined by unanimous agreement of 3 oculoplastic surgeons. Eyebrow curvature was assessed by plotting 15 points along the eyebrow in ImageJ. The fourth-degree polynomial ( y = ax4 + bx3 + cx2 + dx + e ) was fitted to each eyebrow. RESULTS Two hundred seventy-one eyes were analyzed (200 TED and 71 age-sex-matched normal controls). A Rainbow Brow was identified in 42% of TED patients. A unilateral Rainbow Brow was seen in 15% of patients. The fourth-degree polynomial coefficients yielded significant differences between Rainbow Brow patients and age-sex-matched normal controls for the coefficients a, b, c , and d . Similar analysis of TED patients with and without a Rainbow Brow showed differences in coefficients a and b . Age >50 years ( p = 0.009) and the presence of brow fat expansion ( p < 0.001) were associated with the presence of a Rainbow Brow. Proptosis >24 mm showed a trend toward association with the presence of a Rainbow Brow ( p = 0.057). When considering the contribution of these features in a multivariable analysis, only brow fat expansion was a significant contributing factor ( p = 0.009). CONCLUSIONS The Rainbow Brow is a distinct entity in TED and is likely consequent to brow fat pad expansion. Patients with a Rainbow Brow have different eyebrow curvature as compared to both normal age-sex-matched controls and TED patients without a Rainbow Brow.

Abstract
BACKGROUND Pericardial fat (PF) is highly associated with cardiovascular disease but the effectiveness of surgical resection of PF is still unknown for myocardial mitochondrial structure and function in acute myocardial infarction (AMI) with obesity. The aim of this study was to demonstrate the difference in myocardial mitochondrial structure and function between obese AMI with additionally resected PF and those without resected PF. METHODS Obese rats with 12-week high fat diet (45 kcal% fat, n = 21) were randomly assigned into 3 groups: obese control, obese AMI and obese AMI with additionally resected PF. One week after developing AMI and additional resection of PF, echocardiogram, myocardial mitochondrial histomorphology, oxidative phosphorylation system (OXPHOS), anti-oxidative enzyme and sarcoplasmic reticulum Ca2+ ATPase 2 (SERCA2) in the non-infarcted area were assessed between these groups. RESULTS There was significant improvement of systolic function in AMI with PF resection compared with the AMI group in the echocardiogram. Even though the electron microscopic morphology for the mitochondria seems to be similar between the AMI with PF resection and AMI groups, there was an improved expression of PGC-1α and responsive OXPHOS including NDUFB3, NDUFB5 and SDHB are associated with the ATP levels in the AMI with PF resection compared with those in the AMI group. In addition, the expression levels of antioxidant enzymes (MnSOD) and SERCA2 were improved in the AMI with PF resection compared with those in the AMI group. CONCLUSION Surgical resection of PF might ameliorate myocardial mitochondria dysfunction in obese AMI.

Abstract
BACKGROUND Estimating the volume of fat to be resected during lower lid blepharoplasty can be challenging. While the excess fat is clearly visible in the upright position, it retracts into the orbital cavity when the patient is in decubitus. Several tools have been developed to predict the volume required for adequate outcomes and to reduce the risk of complications. Among these, 3D photography, in addition to being noninvasive, radiation-free, portable and relatively inexpensive, can be used to make simulations. OBJECTIVE To assess the level of agreement between Vectra H1 camera simulations and the outcome of lower eyelid blepharoplasties with volume removal based on these simulations. METHODS Preoperatively, a 3D camera and simulation software (Vectra H1, Canfield Imaging Systems) was used to estimate the fat pad volume to be resected from the lower eyelids in a sample of 35 patients (female n = 34) aged 55 years on average. Following the procedure, the patients were photographed at 1, 3 and 6 months and the outcome was compared to the simulation. RESULTS The agreement between the simulated volume and the intraoperative volume was high. While the difference between the postoperative volume and the simulated volume decreased over time, at 6 months the actual volume was still 0.30 mL (right eye) and 0.24 mL (left eye) larger than the simulated volume. CONCLUSIONS A systematic and significant difference was found between the simulation volume and the postoperative volume. The low level of agreement observed suggests that the accuracy of the tested software is insufficient for reliable simulations.

Abstract
CONTEXT Hypertrophy of the infrapatellar fat pad (IFP) in idiopathic knee osteoarthritis has been linked to deleterious synovial changes and joint pain related to mechanical tissue impingement. Yet little is known regarding the IFP's volumetric changes after anterior cruciate ligament reconstruction (ACLR). OBJECTIVES To examine changes in IFP volume between 6 and 12 months after ACLR and determine associations between patient-reported outcomes and IFP volume at each time point as well as the volume change over time. In a subset of individuals, we examined interlimb IFP volume differences 12 months post-ACLR. STUDY DESIGN Prospective cohort study. SETTING Laboratory. PATIENTS OR OTHER PARTICIPANTS We studied 26 participants (13 women, 13 men, age = 21.88 ± 3.58 years, body mass index = 23.82 ± 2.21 kg/m2) for our primary aims and 13 of those participants (8 women, 5 men, age = 21.15 ± 3.85 years, body mass index = 23.01 ± 2.01 kg/m2) for our exploratory aim. MAIN OUTCOME MEASURE(S) Using magnetic resonance imaging, we evaluated the IFP volume change between 6 and 12 months post-ACLR in the ACLR limb and between-limbs differences at 12 months in a subset of participants. International Knee Documentation Committee subjective knee evaluation (IKDC) scores were collected at 6-month and 12-month follow-ups, and associations between IFP volume and patient-reported outcomes were determined. RESULTS The IFP volume in the ACLR limb increased from 6 months (19.67 ± 6.30 cm3) to 12 months (21.26 ± 6.91 cm3) post-ACLR. Greater increases of IFP volume between 6 and 12 months were significantly associated with better 6-month IKDC scores (r = .44, P = .03). The IFP volume was greater in the uninjured limb (22.71 ± 7.87 cm3) than in the ACLR limb (20.75 ± 9.03 cm3) 12 months post-ACLR. CONCLUSIONS The IFP volume increased between 6 and 12 months post-ACLR; however, the IFP volume of the ACLR limb remained smaller than that of the uninjured limb at 12 months. In addition, those with better knee function 6 months post-ACLR demonstrated greater increases in IFP volume between 6 and 12 months post-ACLR. This suggests that greater IFP volumes may play a role in long-term joint health after ACLR.

Abstract
OBJECTIVE The use of autologous fat grafting in the context of breast reconstruction is still a matter of controversy. The objective of this study was to compare the local relapse rate in women who had a fat grafting session in the context of breast reconstruction after breast cancer management, to those who had breast reconstruction without fat grafting. METHODS We performed a retrospective, monocentric, case-control study from January 2007 to December 2017 in our hospital. The cases included women who underwent breast reconstruction with autologous fat grafting and controls, undergoing breast reconstruction without fat grafting. We compared survival and local recurrence between the two groups. RESULTS 412 women were included: 109 (26.5%) in the lipofilling group and 303 women (73.5%) in the "no lipofilling" group. In the overall study population, lipofilling did not appear to be a predictive factor for recurrence, HR = 1.39 [0.63 - 3.06], p = 0.41; or a predictive factor for overall survival, HR = 0.84 [0.23 - 3.02], p = 0.79, or for distant metastases, HR = 1.10 [0.43 - 2.79], p = 0.84. In contrast, in the subgroup of women treated for invasive cancer, the multivariate analysis showed that lipofilling in this context was an independent predictive factor for local recurrence (HR= 5.06 [1.97 - 10.6], p = 0.04). CONCLUSION we found an increased risk of local recurrence after lipofilling in women who were managed for invasive breast cancer. This suggests that special consideration should be given to women who have had invasive breast cancer before lipofilling.

Abstract
SUMMARY Social media have triggered a buccal fat pad excision frenzy. Not surprisingly, there is tremendous appeal of having a slimmer lower face and more defined jawline after undergoing a small intraoral procedure under local anesthesia. Although this procedure is great for social media and seemingly beneficial for jawline aesthetics, the evidence remains limited as to whether or not this is an effective long-term solution. How much the buccal fat pad persists or diminishes as we age is an area of debate. However, the possibility of causing premature aging and midface distortion in the long run is disconcerting.
