A case report of recurrent primary posterior mediastinal perivascular epithelioid cell tumour compressing the right inferior pulmonary vein, atria, and inferior vena cava.

Background: Perivascular epithelioid cell tumours (PEComas) are rare soft tissue neoplasms that commonly occur in the uterus, skin, and liver and less commonly in the retroperitoneum, colon, and mediastinum. Case summary: A 36-year-old male patient with a history of mediastinal PEComa status post resection, essential hypertension, and atrial fibrillation status post appendage ligation currently not on anticoagulation presented with a 1-week history of fevers, chills, productive cough, chest pain, dyspnoea on exertion, loss of appetite, and general weakness. Vital signs, physical exam, laboratory data, electrocardiogram, and chest radiograph were grossly unremarkable. A multimodality imaging approach utilizing transthoracic echocardiogram, transoesophageal echocardiogram (TEE), cardiac magnetic resonance imaging (cMRI), and computed tomography angiography of the chest, abdomen, and pelvis revealed a local 40 mm × 53 mm globular bilobed vascularized scar-free posterior mediastinal mass arising from the roof of the left and right atria and extending superiorly to the main pulmonary artery and inferiorly to the inferior vena cava. Based on the mass' size and proximity to vital structures and tumour recurrence, the case was presented during tumour board rounds, and the outcome was to surgically resect the mass and then have the patient follow up with medical oncology and radiation oncology for possible chemotherapy and radiation, respectively. Discussion: Perivascular epithelioid cell tumours are rare, and mediastinal PEComas are even rarer, warranting a multimodality imaging approach involving TEE and cMRI and a multidisciplinary approach involving anaesthesiologists, cardiologists, cardiothoracic surgeons, medical oncologists, pathologists, radiologists, and radiation oncologists.

Minimizing Nipple-Areolar Complex Complications in Prepectoral Breast Reconstruction After Nipple-Sparing Mastectomy.

PURPOSE: Nipple-areolar complex (NAC) viability remains a significant concern following prepectoral tissue expander (TE) reconstruction after nipple-sparing mastectomy (NSM). This study assesses the impact of intraoperative TE fill on NAC necrosis and identifies strategies for mitigating this risk. METHODS: A chart review of all consecutive, prepectoral TEs placed immediately after NSM was performed between March 2017 and December 2022 at a single center. Demographics, mastectomy weight, intraoperative TE fill, and complications were extracted for all patients. Partial NAC necrosis was defined as any thickness of skin loss including part of the NAC, whereas total NAC necrosis was defined as full-thickness skin loss involving the entirety of the NAC. P < 0.05 was considered statistically significant. RESULTS: Forty-six patients (83 breasts) with an average follow-up of 22 months were included. Women were on average 46 years old, nonsmoker (98%), and nondiabetic (100%) and had a body mass index of 23 kg/m2. All reconstructions were performed immediately following prophylactic mastectomies in 49% and therapeutic mastectomies in 51% of cases. Three breasts (4%) were radiated, and 15 patients (33%) received chemotherapy. Mean mastectomy weight was 346 ± 274 g, median intraoperative TE fill was 150 ± 225 mL, and median final TE fill was 350 ± 170 mL. Partial NAC necrosis occurred in 7 breasts (8%), and there were zero instances of complete NAC necrosis. On univariate analysis, partial NAC necrosis was not associated with any patient demographic or operative characteristics, including intraoperative TE fill. In multivariable models controlling for age, body mass index, mastectomy weight, prior breast surgery, and intraoperative TE fill, partial NAC necrosis was associated with lower body mass index (odds ratio, 0.53; confidence interval [CI], 0.29-0.98; P < 0.05) and higher mastectomy weight (odds ratio, 1.1; CI, 1.01-1.20; P < 0.05). Prior breast surgery approached significance, as those breasts had a 19.4 times higher odds of partial NAC necrosis (95% CI, 0.88-427.6; P = 0.06). CONCLUSIONS: Nipple-areolar complex necrosis following prepectoral TE reconstruction is a rare but serious complication. In this study of 83 breasts, 7 (8%) developed partial NAC necrosis, and all but one were able to be salvaged.

Merit-Based Incentive Payment System: How Are Plastic Surgeons Performing?

PURPOSE: Merit-based incentive payment system (MIPS) is a payment model implemented to promote high-value care through performance-based adjustments of Medicare reimbursements. Higher scores indicate superior performance in healthcare quality, efficiency, and interoperability, which can result in financial advantages. Given the paucity of literature, we aimed to characterize plastic surgery performance in MIPS. METHOD: The Centers for Medicare and Medicaid Services (CMS) online data repository was queried for data on MIPS performance of plastic surgeons from 2019-2021. Descriptive analyses and multivariable logistic regression were conducted to identify predictors of receiving bonus payment for exceptional performance. RESULTS: Approximately 1400 surgeons were sampled in each year. The median number of Medicare beneficiaries and percent of dually eligible beneficiaries-eligible for Medicare and Medicaid-were higher in 2019 (p<0.001). Beneficiary median HCC risk score, which measures expected healthcare costs and needs based on health status, was lower in 2021 (p<0.001). The most common reporting schema was reporting as a group. Total MIPS score increased from 2019 to 2020 to 2021 (90.2 vs 96.4 vs 98.3, p<0.001), but quality score progressively decreased (98.8 vs 95.5 vs 89.90, p<0.001). Fewer physicians received positive adjustment and bonus payments in 2020 and 2021. Predictors of receiving bonus payments were reporting as an alternative payment model, practice size >24, and having 10-49% of dually eligible beneficiaries (p<0.05). CONCLUSION: Understanding performance of plastic surgeons in MIPS can guide future policy direction and ensure that high-quality care translates into improved patient outcomes across all fields and levels of social vulnerability.

Breast Implant Illness as a Clinical Entity: A Systematic Review of the Literature.

BACKGROUND: Breast implant illness (BII) has become a contentious subject in recent years. While some studies have reported associations between breast implants and autoimmune diseases, others have failed to establish a definitive link. OBJECTIVES: The objective of this study is to provide a comprehensive, up-to-date evaluation of the literature surrounding BII, with an emphasis on identifying patient-related factors that may be associated with BII. METHODS: A systematic review was performed following PRISMA guidelines using Pubmed (MEDLINE), EMBASE, and Cochrane databases to search for relevant studies published in the last twenty years. RESULTS: Thirty-one studies were included with a total of 39,505 implant patients and mean age of 44.2 ± 9.30 years. Fifteen studies reported implant explantation status with 72.4% patients choosing to remove their implants. Among these, nine studies reported symptom improvement in 83.5% patients. Fifty-three percent of patients undergoing explantation had total capsulectomy. Twenty-eight studies documented total numbers of patients experiencing symptoms related to BII, with 31.3% patients reporting such symptoms. Among these, sixteen studies of 4,109 BII patients distinguished whether the reason for implantation was cosmetic augmentation or reconstruction. When specified, more patients experiencing BII-related symptoms received implants for "cosmetic" versus "reconstructive" reasons (Cosmetic: 3,864/4,109; 94.0% vs. Reconstruction: 245/4,109; 5.96%, p < 0.001). CONCLUSIONS: This review provides an overview of the current state of knowledge regarding BII. Our study highlights a potential relationship between BII and indication for implants (cosmetic vs. reconstructive) among other variables, offering valuable insight on factors associated with BII and directions for future research.

Artificial intelligence-assisted double reading of chest radiographs to detect clinically relevant missed findings: a two-centre evaluation.

OBJECTIVES: To evaluate an artificial intelligence (AI)-assisted double reading system for detecting clinically relevant missed findings on routinely reported chest radiographs. METHODS: A retrospective study was performed in two institutions, a secondary care hospital and tertiary referral oncology centre. Commercially available AI software performed a comparative analysis of chest radiographs and radiologists' authorised reports using a deep learning and natural language processing algorithm, respectively. The AI-detected discrepant findings between images and reports were assessed for clinical relevance by an external radiologist, as part of the commercial service provided by the AI vendor. The selected missed findings were subsequently returned to the institution's radiologist for final review. RESULTS: In total, 25,104 chest radiographs of 21,039 patients (mean age 61.1 years ± 16.2 [SD]; 10,436 men) were included. The AI software detected discrepancies between imaging and reports in 21.1% (5289 of 25,104). After review by the external radiologist, 0.9% (47 of 5289) of cases were deemed to contain clinically relevant missed findings. The institution's radiologists confirmed 35 of 47 missed findings (74.5%) as clinically relevant (0.1% of all cases). Missed findings consisted of lung nodules (71.4%, 25 of 35), pneumothoraces (17.1%, 6 of 35) and consolidations (11.4%, 4 of 35). CONCLUSION: The AI-assisted double reading system was able to identify missed findings on chest radiographs after report authorisation. The approach required an external radiologist to review the AI-detected discrepancies. The number of clinically relevant missed findings by radiologists was very low. CLINICAL RELEVANCE STATEMENT: The AI-assisted double reader workflow was shown to detect diagnostic errors and could be applied as a quality assurance tool. Although clinically relevant missed findings were rare, there is potential impact given the common use of chest radiography. KEY POINTS: • A commercially available double reading system supported by artificial intelligence was evaluated to detect reporting errors in chest radiographs (n=25,104) from two institutions. • Clinically relevant missed findings were found in 0.1% of chest radiographs and consisted of unreported lung nodules, pneumothoraces and consolidations. • Applying AI software as a secondary reader after report authorisation can assist in reducing diagnostic errors without interrupting the radiologist's reading workflow. However, the number of AI-detected discrepancies was considerable and required review by a radiologist to assess their relevance.

Differential preferences in breast aesthetics by self-identified demographics assessed on a national survey.

There is a paucity of literature examining how preferences differ amongst various demographic groups. This study aimed to assess how perceptions of the ideal breast differ between respondents stratified by self-identified demographic factors. A cohort of 25 patients from the senior surgeon's practice presenting for breast surgery was assembled. Pre-operative anteroposterior photographs of these patients were distributed via Qualtrics (Seattle, WA) to a large sample designed to be representative of the demographics of the United States. Survey questions aimed to measure respondents' impressions of 'breast attractiveness'. Respondents were asked to rate breasts on a Likert scale. Survey responses were analysed for differences in breast aesthetic preferences by sex, gender, sexual orientation, and race. Males rated all breasts higher on the Likert scale for attractiveness than females (2.8 vs 2.5, p < 0.001). Despite this discrepancy, ratings amongst male and female respondents were highly correlated with one another (R = 0.940; p < 0.0001). Considering sexual orientation, individuals attracted to women provided significantly higher attractiveness ratings to all breasts compared to individuals attracted to men only (2.8 vs 2.5, p < 0.001). White or Caucasian individuals ascribed significantly higher breast attractiveness ratings than Asian individuals (2.7 vs 2.2, p < 0.001), but not Black or African American individuals (2.7 vs 2.4, p = 0.23). Despite these racial discrepancies in mean breast attractiveness, ratings amongst the three groups were highly correlated. In a sample representative of the United States, a difference in breast aesthetic appraisal was observed by demographic factors. These findings merit further investigation to understand these trends and observations.

Results of Primary Total Knee Arthroplasty in Patients on Chronic Psychotropic Medications.

BACKGROUND: Psychotropic medications are commonly used to treat several mental health conditions. The aim of this study was to determine the impact of psychotropic medications in patients undergoing primary total knee arthroplasty (TKA) with respect to postoperative opioid use, complications, patient-reported outcome measures, and satisfaction. METHODS: This is a retrospective cohort study of 514 consecutive patients undergoing primary TKA. There were 120 patients (23.3%) who were excluded due to preoperative opioid usage. The remaining 394 patients had a minimum 1-year follow-up. Of those, 133 (34%) were on psychotropic medications preoperatively and were compared to the remaining 261 (66%) patients who were not on psychotropics. Clinical data, satisfaction, Knee Society (KS) scores, Western Ontario McMaster Universities Arthritis Index, Patient-Reported Outcomes Measurement Index Score, Forgotten Joint Scores, Knee Injury and Osteoarthritis Outcome Score for Joint Replacement, postoperative opioid medication usage, and complications were compared. RESULTS: The study cohort (psychotropic medications) had significantly lower postoperative KS Function, KS Knee, Forgotten Joint Scores, Knee Injury and Osteoarthritis Outcome Score for Joint Replacement, Western Ontario McMaster Universities Arthritis Index, and Patient-Reported Outcomes Measurement Index Score compared to the control group. The study group had a lower overall satisfaction score (Likert scale 1 to 5) and a lower percentage of patients either satisfied or very satisfied (4.55 versus 4.79, P < .001; 92.0 versus 97.24%, P = .03, respectively). Postoperative opioid usage was significantly greater in the study group at both 6.4 weeks (range, 4 to 8) and 12-month follow-up (52.76 versus 13.33%, P < .001; 5.51 versus 0.39%, P = .002, respectively). There were no differences in complications and revisions between the groups. CONCLUSIONS: Patients on psychotropic medications should be educated on the risk of increased opioid consumption, diminished satisfaction, and patient-reported outcome measures following primary TKA. Given the large number of patients on psychotropic medications undergoing TKA, additional studies are needed to further improve clinical outcomes in this group.

Artificial Intelligence as a Triage Tool during the Perioperative Period: Pilot Study of Accuracy and Accessibility for Clinical Application.

Background: Given the dialogistic properties of ChatGPT, we hypothesized that this artificial intelligence (AI) function can be used as a self-service tool where clinical questions can be directly answered by AI. Our objective was to assess the content, accuracy, and accessibility of AI-generated content regarding common perioperative questions for reduction mammaplasty. Methods: ChatGPT (OpenAI, February Version, San Francisco, Calif.) was used to query 20 common patient concerns that arise in the perioperative period of a reduction mammaplasty. Searches were performed in duplicate for both a general term and a specific clinical question. Query outputs were analyzed both objectively and subjectively. Descriptive statistics, t tests, and chi-square tests were performed where appropriate with a predetermined level of significance of P less than 0.05. Results: From a total of 40 AI-generated outputs, mean word length was 191.8 words. Readability was at the thirteenth grade level. Regarding content, of all query outputs, 97.5% were on the appropriate topic. Medical advice was deemed to be reasonable in 100% of cases. General queries more frequently reported overarching background information, whereas specific queries more frequently reported prescriptive information (P < 0.0001). AI outputs specifically recommended following surgeon provided postoperative instructions in 82.5% of instances. Conclusions: Currently available AI tools, in their nascent form, can provide recommendations for common perioperative questions and concerns for reduction mammaplasty. With further calibration, AI interfaces may serve as a tool for fielding patient queries in the future; however, patients must always retain the ability to bypass technology and be able to contact their surgeon.

Results of a Highly Porous Metal-Backed Cementless Patella Implant: A Minimum 5-Year Follow-Up.

Initial design cementless metal-backed patellar implants failed due to multiple reasons including implant design, use of first-generation polyethylene, and surgical technique. This study evaluates clinical outcomes and survivorship of total knee arthroplasty (TKA) using a current generation highly porous metal-backed patellar component. One-hundred twenty-five consecutive primary cementless TKAs with a compression molded highly porous metal-backed patella were reviewed. One-hundred three TKAs (82.4%) with 5-year clinical and radiographic follow-up were available for review. These were matched with 103 consecutive TKAs using a cemented patella of the same implant design. The cementless cohort had a mean age of 65.5 years, body mass index (BMI) of 33.0, and follow-up of 64.4 months. Indications for cementless TKA were based on multiple factors including age, BMI, and bone quality. There were no revisions for loosening or mechanical failure of the cementless patella compared with two cemented patellae revised for aseptic loosening. Eight patients required revisions in the cementless cohort: three for prosthetic joint infection (PJI), two for instability, one periprosthetic femur fracture, one for patella instability, and one for extensor mechanism rupture. Five patients required revisions in the cemented cohort: two for aseptic patellar loosening, one for aseptic femoral loosening, one for PJI, and one for instability. All-cause survivorship at 5 years was 92.2 and 95.1% for the cementless metal-backed implant and cemented implant cohorts, respectively. Use of a compression molded highly porous metal-backed patella component demonstrated excellent clinical and radiographic results at 5-year follow-up. Longer follow-up is required to evaluate the ability of highly porous cementless patella implants to provide durable long-term fixation.

Low Cancer Occurrence Rate following Prophylactic Nipple-Sparing Mastectomy.

BACKGROUND: Nipple-sparing mastectomy (NSM) has become widely available for breast cancer prophylaxis. There are limited data on its long-term oncologic safety. The objective of this study was to determine the incidence of breast cancer in patients who underwent prophylactic NSM. METHODS: All patients undergoing prophylactic NSM at a single institution from 2006 through 2019 were retrospectively reviewed. Patient demographic factors, genetic predispositions, mastectomy specimen pathology, and oncologic occurrences at follow-up were recorded. Descriptive statistics were performed where necessary to classify demographic factors and oncologic characteristics. RESULTS: A total of 871 prophylactic NSMs were performed on 641 patients, with median follow-up of 82.0 months (standard error 1.24). A total of 94.4% of patients ( n = 605) underwent bilateral NSMs, although only the prophylactic mastectomy was considered. The majority of mastectomy specimens (69.6%) had no identifiable pathology. A total of 38 specimens (4.4%) had cancer identified in mastectomy specimens, with ductal carcinoma in situ being the most common (92.1%; n = 35). Multifocal or multicentric disease was observed in seven cases (18.4%) and lymphovascular invasion was identified in two (5.3%). One patient (0.16%), who was a BRCA2 variant carrier, was found to have breast cancer 6.5 years after prophylactic mastectomy. CONCLUSIONS: Overall primary oncologic occurrence rates are very low in high-risk patients undergoing prophylactic NSM. In addition to reducing the risk of oncologic occurrence, prophylactic surgery itself may be therapeutic in a small proportion of patients. Continued surveillance for these patients remains important to assess at longer follow-up intervals. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, IV.

Revision and Primary Meniscal Allograft Transplantations Provide Clinical Benefit at Mid-Term Follow-Up: A Matched-Cohort Analysis of Patient-Reported Outcomes, Reoperations, and Failures.

PURPOSE: To report the mid-term outcomes of patients who underwent revision meniscal allograft transplantation (RMAT) and compare survivorship free from reoperation and failure with a matched cohort of patients who underwent primary meniscal allograft transplantation (PMAT). METHODS: A retrospective review of prospectively collected data identified patients who underwent RMAT and PMAT between 1999 and 2017. A cohort of PMAT patients matched at a ratio of 2:1 with respect to age, body mass index, sex, and concomitant procedures served as the control group. Patient-reported outcome measures (PROMs) at baseline and at a minimum of 5 years postoperatively were collected. PROMs and the achievement of clinically significant outcomes were analyzed within groups. Graft survivorship free from meniscal reoperation and failure (arthroplasty or subsequent RMAT) was compared between cohorts using log-rank testing. RESULTS: During the study period, 22 RMATs were performed in 22 patients. Of these RMAT patients, 16 met the inclusion criteria (73% follow-up rate). The mean age of RMAT patients was 29.7 ± 9.3 years, and the mean follow-up period was 9.9 ± 4.2 years (range, 5.4-16.8 years). There were no differences between the RMAT cohort and the 32 matched PMAT patients with respect to age (P = .292), body mass index (P = .623), sex (P = .537), concomitant procedures (P ≥ .286), or baseline PROMs (P ≥ .066). The patient acceptable symptomatic state was achieved by the RMAT cohort for the subjective International Knee Documentation Committee score (70%), Lysholm score (38%), and Knee Injury and Osteoarthritis Outcome Score subscales (Pain [73%], Symptoms [64%], Sport [45%], Activities of Daily Living [55%], and Quality of Life [36%]). In the RMAT cohort, 5 patients (31%) underwent subsequent reoperation at a mean of 4.7 ± 2.1 years (range, 1.7-6.7 years) and 5 patients met the criteria for failure at a mean of 4.9 ± 2.9 years (range, 1.2-8.4 years). There were no significant differences in survivorship free from reoperation (P = .735) or failure (P = .170) between the RMAT and PMAT cohorts. CONCLUSIONS: At mid-term follow-up, most patients who underwent RMAT achieved the patient acceptable symptomatic state for the subjective International Knee Documentation Committee score and the Knee Injury and Osteoarthritis Outcome Score subscales of Pain, Symptoms, and Activities of Daily Living. Additionally, there were no differences in survival free from meniscal reoperation or failure between the PMAT and RMAT cohorts. LEVEL OF EVIDENCE: Level III, retrospective comparative cohort.

Transgender Incarceration and Law Enforcement as a Source of Harm: Upstream and Primordial Prevention Perspectives.

In the United States (US), transgender individuals are more likely to experience violence and sexual assault in jails and prisons compared with cisgender peers. Harms of incarceration on transgender individuals include limited access to medical care and hormone therapy, as well as being housed in facilities based on biological sex instead of gender identity. However, there has been insufficient research on addressing factors that lead to transgender individuals being incarcerated in the first place. In this article, we argue the need to focus on law enforcement interactions with transgender individuals in the US to reduce incarceration-related harms. Using the perspectives of primordial prevention and focusing on upstream factors that create health-related harms, we assert that focusing on law enforcement is a necessary component in addressing how the criminal justice system harms transgender individuals.

Preauthorization Inconsistencies Prevail in Reduction Mammaplasty.

Background: Despite evidence documenting the physical and psychological benefits of breast reduction, third-party payer approval remains a cumbersome process. The objective of this study was to assess differences in medical necessity criteria for reduction mammaplasty among US insurance carriers while analyzing trends in claim denials and appeals. Methods: The medical necessity criteria for reduction mammaplasty were retrieved from seven large health insurance carriers. Data were extracted from each policy, including claim requirements for approval. Additionally, prospective data on claims and denials submitted from January through August 2022 were collected from The Auctus Group, a medical consulting firm. Results: All the policies have been updated since January 2020. Five of the seven policies specifically listed what documentation was required for preauthorization approval, with five third-party payers requiring photograph documentation. Policies required documentation of one to three symptoms lasting from 6 weeks to 1 year. All companies reported a tissue resection estimate threshold, but cutoffs varied. Of 380 reduction mammaplasties performed, 158 (41.6%) received a denial on initial insurance submission. Considering appeals, a total of 216 denials were reviewed with an average of 1.37 denials per patient. Of the 158 initial denials, 104 (65.8%) of these were from claims that received preauthorization. In 12 cases, third-party payers stated that no prior authorization was necessary yet still denied the claim. Conclusions: Wide variability exists in medical necessity criteria for reduction mammaplasty policies among major insurance carriers. These nuances introduce inefficiencies for practices contributing to high denial and appeal rates while delaying surgical care for patients.

Maximizing volume in autologous breast reconstruction: stacked/conjoined free flaps.

Since the first report of abdominally based tissue breast reconstruction with a free flap of rectus abdominis muscle to reconstruct mastectomy defects, autologous breast reconstruction has continually increased in popularity due to improved cosmesis, patient satisfaction, and quality of life. While abdominal tissue is frequently used as the principal donor site, other flap options are available, including from the buttocks, thighs, and back. Microsurgical advancements in recent years have continued to improve patient outcomes and decrease operative times. One innovative technique is the use of stacked or conjoined free flaps which can be used when more breast volume is needed than can be provided by one free flap alone. These stacked or conjoined free flaps can be used unilaterally or bilaterally and can include combinations of nearly every free flap depending on the volume of tissue desired for the reconstruction. Though these flaps are increasing in popularity, there is limited comparative data on the safety and efficacy of stacked or conjoined free flaps as compared to single free flaps. In this review, we aim to highlight the use of stacked/conjoined free flaps for autologous breast reconstruction, as well as highlight recent data on this technique and provide recommendations for its safe use.

High-Level Competitive Athletes Who Undergo Hip Arthroscopy Demonstrate Durable 5-Year Outcomes and Lower Subjective Pain: A Propensity-Matched Analysis.

BACKGROUND: Hip arthroscopy (HA) has been proven to be an effective treatment for femoroacetabular impingement syndrome (FAIS) in both competitive athletes (CA) and non-CA at short-term follow-up. However, there is a paucity of literature investigating midterm outcomes comparing athletes with Controls. HYPOTHESIS: Athletes would have significant improvements at 5 years, with favorable outcomes compared with their control counterparts, and high return-to-sport (RTS) rate. STUDY DESIGN: Propensity-matched retrospective comparative cohort study. LEVEL OF EVIDENCE: Level 3. METHODS: CAs who underwent primary HA for FAIS from January 1, 2012 to April 30, 2017 were identified and propensity matched on a 1:4 basis to Controls by age, sex, and body mass index (BMI). Patient-reported outcomes (PROs) were collected preoperatively and at 5 years. Minimal clinically important differences (MCID) and patient acceptable symptom states (PASS) rates were calculated using previously published thresholds. Rate and duration of RTS were collected retrospectively. RESULTS: A total of 57 high-level CA (33 female, 24 male; age, 21.7 ± 4.2 years; BMI, 23.1 ± 2.8 kg/m2) were propensity matched to 228 Controls (132 female, 96 male; P > 0.99; age, 23.3 ± 5.8 years; P = 0.02; BMI, 23.8 ± 4.3 kg/m2, P = 0.24). Significant differences were observed in preoperative Hip Outcome Score Sports Specific and Activities of Daily Living (HOS-ADL) subscales (CA, 74.9 ± 13.7 vs Controls, 66.4 ± 18.4; P = 0.01) and modified Harris Hip Score (mHHS) (CA, 64.7 ± 12.9 vs Controls, 59.7 ± 14.3; P = 0.04). Both groups demonstrated significant postoperative improvements in all outcome scores measured (P ≤ 0.01). At 5 years postoperatively, there were significant differences between groups in Visual Analog Scale (VAS) Pain (CA, 17.3 ± 17.6 vs Controls, 24.7 ± 25.9; P = 0.02). There were no significant differences in achieving MCID or PASS. Athletes RTS at a median of 25.2 weeks (Q1 22.4-Q3 30.7) with an overall RTS rate of 90%. Similar rates of revision were seen between CA patients (n = 3; 5.3%) and Control patients (n = 9; 3.9%) (P = 0.66). CONCLUSION: CAs demonstrated significant and durable improvements in PROs as well as high MCID and PASS achievement rates after primary HA, which were comparable with those of Controls. Clinicians should be aware that CA patients demonstrate higher preoperative mHHS and HOS-ADL scores than Controls and achieve lower average self-reported pain at 5 years postoperatively. In addition, CA patients demonstrate high rates of RTS at a median of 25 weeks postoperatively. CLINICAL RELEVANCE: This study provides insight into CA versus Control PROs and rates of achieving MCID and PASS at a midterm follow-up of 5 years. Furthermore, this study offers perception into RTS rate, both in general as well as specified to individualized sports.

No Cancer Occurrences in 10-year Follow-up after Prophylactic Nipple-sparing Mastectomy.

Prophylactic nipple-sparing mastectomies (NSM) have become increasingly common, although there is little long-term data on its efficacy in prevention of breast cancer. The objective of this study was to assess the incidence of breast cancer in a cohort of patients undergoing prophylactic NSM with a median follow-up of 10 years. Methods: Patients receiving prophylactic NSM at a single institution from 2006 to 2019 were included in a retrospective nature. Patient demographics, genetic mutations, operative details, and specimen pathology were recorded, and all postoperative patient visits and documentation were screened for cancer occurrence. Descriptive statics were performed where appropriate. Results: Two hundred eighty-four prophylactic NSMs were performed on 228 patients with a median follow-up of 120.5 ± 15.7 months. Roughly, a third of patients had a known genetic mutation, with 21% BRCA1 and 12% BRCA2. The majority (73%) of prophylactic specimens had no abnormal pathology. The most commonly observed pathologies were atypical lobular hyperplasia (10%) and ductal carcinoma in situ (7%). Cancer was identified in 10% of specimens, with only one case of lymphovascular invasion. Thus far, there have been no incidences of locoregional breast cancer occurrence in this cohort. Conclusions: The long-term breast cancer occurrence rate in this cohort of prophylactic NSM patients at the time of this study is negligible. Despite this, continued surveillance of these patients is necessary until lifetime risk of occurrence following NSM has been established.

Indications and outcomes of glenoid osteotomy for posterior shoulder instability: a systematic review.

Background: There is limited evidence examining glenoid osteotomy as a treatment for posterior shoulder instability. Methods: A search of Medline, Embase, PubMed and Cochrane Central Register of Controlled Trials was conducted from the date of origin to 28th November 2019. Nine out of 3,408 retrieved studies met the inclusion criteria and quality was assessed using the Methodological Index for Non-randomized Studies tool. Results: In 356 shoulders, the main indication for osteotomy was excessive glenoid retroversion (greater than or equal to approximately -10°). The mean preoperative glenoid version was -15° (range, -35° to -5°). Post-operatively, the mean glenoid version was -6° (range, -28° to 13°) and an average correction of 10° (range, -1° to 30°) was observed. Range of motion increased significantly in most studies and all standardized outcome scores (Rowe, Constant-Murley, Oxford instability, Japan Shoulder Society Shoulder Instability Scoring and mean shoulder value) improved significantly with high rates of patient satisfaction (85%). A high complication rate (34%, n = 120) was reported post-surgery, with frequent cases of persistent instability (20%, n = 68) and fractures (e.g., glenoid neck and acromion) (4%, n = 12). However, the revision rate was low (0.6%, n = 2). Conclusion: Glenoid osteotomy is an appropriate treatment for posterior shoulder instability secondary to excessive glenoid retroversion. However, the high rate of persistent instability should be considered when making treatment decisions.Level of Evidence: Systematic review; Level 4.

Results of Endoscopic Labral Repair With Concomitant Gluteus Medius and/or Minimus Repair Compared With Outcomes of Labral Repair Alone: A Matched Comparative Cohort Analysis at Minimum 2-Year Follow-up.

BACKGROUND: There is a paucity of information available to clinicians on outcomes of patients undergoing endoscopic surgery for labral repairs and femoroacetabular impingement syndrome with simultaneous repair of the gluteus medius and/or minimus muscles. PURPOSE: To determine whether patients with labral tears and concomitant gluteal pathology who undergo simultaneous endoscopic labral and gluteus medius and/or minimus repair experience similar outcomes to patients with isolated labral tears who undergo endoscopic labral repair alone. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: A matched retrospective comparative cohort study was performed. Patients who underwent gluteus medius and/or minimus repair with concomitant labral repair between January 2012 and November 2019 were identified. These patients were matched in a 1:3 ratio by sex, age, and body mass index (BMI) to patients who underwent labral repair alone. Preoperative radiographs were assessed. Patient-reported outcomes (PROs) were assessed preoperatively and 2 years postoperatively. PRO measures included the Hip Outcome Score Activities of Daily Living and Sports subscales, modified Harris Hip Score, 12-Item International Hip Outcome Tool, and visual analog scales for pain and satisfaction. Published labral repair minimal clinically important difference (MCID) and Patient Acceptable Symptom State (PASS) thresholds were utilized for these measures. RESULTS: A total of 31 patients who underwent gluteus medius and/or minimus repair with concomitant labral repair (27 female, 4 male; age, 50.8 ± 7.3 years; BMI, 27.9 ± 5.2) were matched with 93 patients who underwent labral repair alone (81 female, 12 male; age, 50.9 ± 8.1 years; BMI, 28.5 ± 6.2). There were no significant differences in sex (P > .99), age (P = .869), or BMI (P = .592); preoperative radiographic measurements; or preoperative or 2-year postoperative PRO scores (P≥ .081). Changes between preoperative and 2-year postoperative PRO scores were significantly different for both groups for all PROs assessed (P < .001 for all). There were no significant differences in MCID or PASS achievement rates (P≥ .123), with low PASS achievement rates of 40% to 60% found in both groups. CONCLUSION: Patients who were treated with endoscopic gluteus medius and/or minimus repair with concomitant labral repair demonstrated comparable outcomes with those who were treated with endoscopic labral repair alone.
