Novel motor-sparing blocks, the pericapsular nerve group (PENG) and lateral femoral cutaneous nerve (LFCN) block, have shown efficacy in hip surgery. Purpose: We sought to investigate the analgesic benefits of these novel blocks in terms of opioid-sparing and discharge efficiency. Methods: We conducted a retrospective cohort study with propensity score matching of 224 patients who underwent ambulatory elective unilateral hip arthroscopy. One group received a combined PENG and LFCN block (PENG/LFCN, n = 86), while a second group received only a PENG block (n = 26). A control group (n = 112) received no blocks. The primary outcome was postanesthesia care unit (PACU) mean opioid consumption. Secondary outcomes were maximum numeric rating scale (NRS) pain score, intravenous rescue analgesia, and PACU readiness-for-discharge times. Results: The PENG/LFCN-block group required significantly less opioids than the control group in the PACU (25.98 ± 13.04 vs 14.58 ± 5.77, respectively) and were discharged earlier 2.72 ± 1.16 vs 4.42 ± 1.63 hours, respectively). The combined PENG/LFCN group also used less intravenous rescue opioids than the control group (0.47 ± 1.18 vs 1.44 ± 2.1 mg, respectively) and showed a significant difference in the highest NRS pain scores than the control group (6.01 ± 2.38 vs 6.77 ± 2.1 respectively). The PENG block alone group did not show a significant difference in opioid reduction (21.95 ± 15.83 vs 27.72 ± 15.01, respectively). Conclusions: This retrospective study found that in patients who underwent ambulatory elective unilateral hip arthroscopy, a combined PENG and LFCN block was associated with expedited PACU discharge and a clinically significant reduction in postoperative opioid use. Further study is warranted.","PeriodicalId":35357,"journal":{"name":"Hss Journal","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135426142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Purpose: We sought to determine how well randomized controlled trials (RCTs) on MSC intervention for knee osteoarthritis (OA) adhered to the MIBO guidelines. Methods: A comprehensive literature search was performed in the PubMed/MEDLINE and Web of Science databases. Inclusion criteria included English-only RCTs that assessed MSC intervention for knee OA published between 2018 and 2022. Metrics were extracted, including year of publication, study design, first author name, journal name, patient demographics, and MIBO checklist criteria. Results: In 27 RCTs analyzed, 1006 patients were included, with a weighted male percentage of 41.8% and weighted mean age of 60.5 ± 7.2 years. On average, 70.5% (range, 30.2%–90.6%) of the modified 53-point MIBO checklist elements were reported per article. Seven (25.9%) articles had adherence rates of 80% or more, 13 (48.1%) had rates between 60% and 79.9%, and 7 (25.9%) had rates of 59.9% or less. The MIBO “intervention” category had the greatest adherence (100%), while the other categories had more variability. Six (50.0%) categories had an adherence level of 80% or more, 3 (25.0%) had adherence levels of 60% to 79.9%, and 3 (25.0%) had an adherence level of 59.9% or less.

As skeletal health is critical to success of orthopedic surgery, the gut microbiome may be a modifiable factor associated with postoperative outcomes. For spine fusion surgery in particular, de novo bone formation and sufficient bone mineral density are essential for successful outcomes. Given the prevalence and complexity of these procedures, the identification of novel factors that may be related to operative success is important. Questions/purposes: We sought to investigate how the composition of the microbiota related to bone health in a focused spinal fusion surgery cohort. Methods: We investigated the composition of the microbiome in a cohort of 31 patients prior to spinal fusion surgery, as well as changes in the microbiome over 6 weeks postoperatively. Preoperative areal bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry. Results: Composition of gut microbiota differed among spinal fusion patients with low bone mass ( T-score ≤ −1.0) and those with normal BMD ( P = .03). There was no significant change in composition of the gut microbiota between preoperative evaluation and 6 weeks postoperatively. Conclusions: Our findings in this small sample suggest there may be a relationship between BMD and composition of the gut microbiome in patients who undergo spinal fusion surgery. Further work is needed to investigate these relationships as well as potential interventions to foster a favorable microbial composition in spinal fusion surgery patients.","PeriodicalId":35357,"journal":{"name":"Hss Journal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134957844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Purpose: Using the area deprivation index (ADI), a validated, weighted index of material deprivation and poverty (a 0%-to-100% scale, with higher percentages indicating greater disadvantage), we sought to evaluate whether there are associations in shoulder arthroplasty patients between higher ADI and rates of (1) medical complications, (2) emergency department (ED) utilizations, (3) readmissions, and (4) costs. Methods: We queried the PearlDiver nationwide database for patients who had undergone primary shoulder arthroplasty from 2010 to 2020. Patients from regions associated with high ADI (95%+) were 1:1 propensity matched to a comparison group by age, sex, and Elixhauser Comorbidity Index. This yielded 49,440 patients in total. Outcomes included 90-day complications, ED utilizations, readmissions, and costs. Logistic regression models computed odds ratios (ORs) of ADI on the dependent variables. P values of < .05 were significant. Results: Patients from high ADI regions showed higher rates and odds of complications than those in the comparison group (10.84% vs 9.45%; OR: 1.10), including acute kidney injuries (1.73% vs 1.38%; OR: 1.23), urinary tract infections (3.19% vs 2.80%; OR: 1.13), and respiratory failures (0.49% vs 0.33%; OR: 1.44), but not increased ED visits (2.66% vs 2.71%; OR: 0.99) or readmissions (3.07% vs 2.96%; OR: 1.03). Patients from high ADI regions incurred higher costs on day of surgery ($8251 vs $7337) and at 90 days ($10,999 vs $9752). Conclusions: This 10-year retrospective database study found that patients from high ADI regions undergoing primary shoulder arthroplasty had increased rates of all 90-day medical complications, suggesting that measures of social determinants of health could inform health care policy and improve post-discharge care in these patients.","PeriodicalId":35357,"journal":{"name":"Hss Journal","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135878225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nonetheless, the incidence, etiology, and procedure-specific risk of saphenous nerve injury after knee surgery with ACB have not been established. We sought to identify the risk of saphenous nerve injury during knee surgery with ACB. We conducted a retrospective cohort study of patients at a single institution who underwent elective knee surgery with ultrasound-guided ACB between January 1, 2014, and December 31, 2018, and had subsequent saphenous nerve injury. The primary outcome was the incidence of saphenous nerve injury within 3 months of surgery, by surgical type and approach. Secondary outcomes included attribution of the most likely etiology and clinical outcome of the injury. In 28,196 cases of knee surgery with ACB, we identified 18 cases (0.06%) of saphenous nerve injury. The most common surgery associated with saphenous nerve injury was anterior cruciate ligament (ACL) reconstruction with autograft (8/18 cases); 3 cases of injury were seen after TKA, 2 after medial patellofemoral ligament reconstruction, 2 after arthroscopy/meniscal surgery, and 1 after patellar fixation. The most likely etiology of nerve injury was attributed to ACB in 5 of 18 cases (28%) and to non-ACB cause in 13 of 18 (72%). Prognosis was rated as unknown in 11 of 18, poor in 2 of 18, favorable in 3 of 18, and full recovery in 2 of 18. This 5-year retrospective, single-institution cohort study found a low overall incidence of saphenous nerve injury after knee surgery with ACB, but the injury likelihood varied based on surgery and approach. Although not statistically significant, ACL reconstruction with hamstring autograft and ACB performed for postoperative rescue analgesia were most frequently associated with nerve injury.","PeriodicalId":35357,"journal":{"name":"Hss Journal","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135878774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Purpose: We sought to evaluate risk factors for incident clinical and incident radiographic hip OA among middle-aged and older adults, to evaluate the importance of risk factors from a preventive perspective, and to estimate the percentage of new cases attributable to these risk factors. Methods: We retrospectively reviewed data from the Rotterdam study, an open-population cohort study of individuals aged 55 years or older. Data including baseline age, sex, body mass index, smoking status, education level, diagnosis of diabetes, C-reactive protein (CRP), cam morphology, acetabular dysplasia, radiographic thumb OA, radiographic hip OA, and hip pain were assessed for their association with incident clinical hip OA and incident radiographic hip OA separately, after 11 years of follow-up. The population-attributable fractions (PAFs) of statistically significant modifiable risk factors were calculated, as well. Results: New onset of clinical hip OA was seen in 19.9% (544 of 2729) and incident radiographic hip OA in 9.9% (329 of 3309).

Because it preserves the native knee joint and its ligamentous stability, DFVO is preferred to total knee arthroplasty (TKA) in the young, active population. Purpose: We sought to assess return to work (RTW) and return to sport (RTS) rates following DFVO for valgus malalignment of the knee. Methods: For this systematic review, we searched EMBASE, MEDLINE, and Web of Science from inception through December 31, 2020. English language studies of all levels of evidence explicitly reporting on RTS and RTW rates following DFVO for valgus malalignment of the knee were eligible for inclusion. Results: Seven studies and 127 patients were included in our analysis. Mean age was 32.4 ± 8.8 years with men comprising 46.7% ± 22.3% of study populations. The mean RTS rate was 87.2% ± 10.7%, with a return to preoperative activity levels rate of 65.4% ± 26.8%.
