Intra-operative subperiosteal elevation of the ulnar nerve is a safe and effective way to minimize post-operative ulnar neuritis in distal humerus fractures.

OBJECTIVES: To describe subperiosteal elevation of the ulnar nerve and compare to anterior transposition and in situ decompression techniques. METHODS: Design: Retrospective comparative study. SETTING: Urban Level 1 trauma center. PATIENT SELECTION CRITERIA: Distal humerus fractures (OTA/AO 13) treated with open reduction internal fixation between 2014-2022. OUTCOME MEASURES AND COMPARISONS: Rate of pre- and post-operative neuritis grouped by management of the ulnar nerve. During subperiosteal elevation, the ulnar nerve was identified and raised off the ulna subperiosteally and mobilized submuscularly anterior to the medial epicondyle to protect the nerve. The nerve was released only laterally off the triceps and the medial soft tissue attachment is maintained. The main outcomes measurements was rate of neuritis documented within physical exam. RESULTS: Within the 125 patients, 35 underwent subperiosteal elevation (mean age of 56 ± 21 years, 57% female), 63 in situ decompression (mean age of 60 ± 18 years, 46% female), and 27 anterior transposition (mean age of 55 ± 20 years, 59% female). Pre-operative ulnar neuritis was present in 34%, 21%, and 33% of patients treated with subperiosteal elevation, in situ decompression, and anterior transposition, respectively (p=0.26). At post-operative evaluation symptom resolution occurred in 100%, 69%, and 33% of patients treated with subperiosteal elevation, in situ decompression, and anterior transposition, respectively (p=0.003). New cases of post-operative ulnar neuritis occurred in 6%, 8%, and 26% of patients treated with subperiosteal elevation, in situ decompression, and anterior transposition, respectively (p=0.054). Subperiosteal elevation outperformed anterior transposition regarding post-operative ulnar neuritis (p=0.019) and symptom resolution (p=0.002) and performed similarly to in situ decompression (p>0.05). On multiple regression analysis, anterior transposition was an independent risk factor for post-operative neuritis (OR=5.2, p=0.023). CONCLUSIONS: Subperiosteal elevation is an effective way to minimize post-operative neuritis and similar to an in-situ decompression during distal humerus fracture fixation. Based on the results of this cohort, authors recommended that anterior transposition of the ulnar nerve be used with caution due to association with post-operative ulnar neuritis. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Reduced Surface Recombination in Extended-Perimeter LEDs toward Electroluminescent Cooling.

III-V semiconductor light-emitting diodes (LEDs) are a promising candidate for demonstrating electroluminescent cooling. However, exceptionally high internal quantum efficiency designs are paramount to achieving this goal. A significant loss mechanism preventing unity internal quantum efficiency in GaAs-based devices is nonradiative surface recombination at the perimeter sidewall. To address this issue, an unconventional LED design is presented, in which the distance from the central current injection area to the device's perimeter is extended while maintaining a constant front contact grid size. This approach effectively moves the perimeter beyond the lateral spread of current at an operating current density of 101-102 A/cm2. In p-i-n GaAs/InGaP double heterojunction LEDs fabricated with varying sizes and perimeter extensions, a 19% relative increase in external quantum efficiency is achieved by extending the perimeter-to-contact distance from 25 to 250 µm for a front contact grid size of 450 × 450 µm2. Utilizing an in-house developed Photon Dynamics model, the corresponding relative increase in internal quantum efficiency is estimated to be 5%. These results are ascribed to a significant reduction in perimeter recombination due to a lower perimeter-to-surface area (P/A) ratio. However, in contrast to lowering the P/A ratio by increasing the front contact grid size of LEDs, the present method enables these improvements without affecting the required maximum current density in the microscopic active LED area under the front contact grid. These findings aid in the advancement of electroluminescent cooling in LEDs and could prove useful in other dedicated semiconductor devices where perimeter recombination is limiting.

Association Between Social Media Activity and Ratings on Physician Review Websites Among Orthopaedic Surgeons With an Active Online Media Presence.

Background: Social media has the potential to play a substantial role in the decision-making of patients when choosing a physician for care. Purpose: The purpose of this study was to determine whether an association exists between physician social media activity and patient satisfaction ratings on physician review websites (PRWs) as well as number of reviews. It was hypothesized that there would be a significant association between physician social media utilization and patient satisfaction ratings. Study Design: Cross-sectional study. Methods: The American Orthopaedic Society for Sports Medicine database was queried for the complete membership list. The online media profile and level of activity of the members were evaluated, and an online media presence score was calculated. The surgeons with the approximately top 10% of online media presence scores were compiled to assess the relationship between social media usage (Twitter, Instagram, YouTube, and Facebook) and patient satisfaction ratings on the Google Reviews, Healthgrades, and Vitals PRWs. Bivariate analysis was performed to compare demographic variables and level of online presence. Results: A total of 325 surgeons were included in the analysis. The most common platform used was Facebook (88.3%). There was no significant relationship between active social media use and overall ratings on any of the PRWs. Active Twitter use was associated with a greater number of ratings on all review websites, a greater number of comments on Google Reviews and Healthgrades, and shorter patient-reported clinic wait times on Healthgrades. Active Instagram use was associated with a greater number of comments on Vitals. No relationships were observed for YouTube or Facebook. Conclusion: For the included sports medicine surgeons who were most active on social media, no significant relationships were found between social media use and overall ratings on PRWs. Of all the platforms assessed, active use of Twitter was the only significant predictor of more reviews on PRWs. Thus, when deciding which form of social media engagement to prioritize in building one's practice, Twitter may serve as a relatively low-demand, high-reward option.

Capsular Management at the Time of Hip Arthroscopy for Femoroacetabular Impingement Syndrome Varies With Geography and Surgeon Subspecialty Training: A Cross-Sectional, Multinational Surgeon Survey.

PURPOSE: To perform a multinational survey and identify patterns in capsular management at the time of hip arthroscopy. METHODS: An anonymous, nonvalidated survey was distributed by the American Orthopaedic Society for Sports Medicine; Arthroscopy Association of North America; European Society of Sports Traumatology, Knee Surgery & Arthroscopy; International Society for Hip Arthroscopy; and Turkish Society of Sports Traumatology, Arthroscopy, and Knee Surgery. The questions were broken down into 6 categories: demographic characteristics, capsulotomy preference, traction stitches, capsular closure, postoperative rehabilitation, and postoperative complications. RESULTS: The survey was completed by 157 surgeons. Surgeons who performed half or full T-type capsulotomies had 2.4 higher odds of using traction sutures for managing both the peripheral and central compartments during hip arthroscopy for femoroacetabular impingement (P = .024). Surgeons who believed that there was sufficient literature regarding the importance of hip capsular closure had 1.9 higher odds of routinely performing complete closure of the capsule (P = .044). Additionally, surgeons who practiced in the United States had 8.1 higher odds of routinely closing the capsule relative to international surgeons (P < .001). Moreover, surgeons who received hip arthroscopy training in residency or fellowship had 2.4 higher odds of closing the capsule completely compared with surgeons who did not have exposure to hip arthroscopy during their training (P = .009). CONCLUSIONS: Geographic and surgeon-related variables correlate with capsular management preferences during hip arthroscopy. Surgeons who perform half or full T-capsulotomies more often use traction stitches for managing both the peripheral and central compartments. Surgeons performing routine capsular closure are more likely to believe that sufficient evidence is available to support the practice, with surgeons in the United States being more likely to perform routine capsular closure in comparison to their international colleagues. CLINICAL RELEVANCE: As the field of hip preservation continues to evolve, capsular management will likely continue to play an important role in access, instrumentation, and postoperative outcomes.

Differentiation of benign and metastatic lymph nodes in soft tissue sarcoma.

Lymph node metastasis (LNM) occurs in less than 5% of soft tissue sarcoma (STS) patients and indicates an aggressive course of disease. Suspicious lymph nodes (LN) in staging imaging are a frequent topic of discussion in multidisciplinary tumor boards. Predictive markers are needed to facilitate stratification and improve treatment of STS patients. In this study, 56 STS patients with radiologically suspicious and subsequently histologically examined LN were reviewed. Patients with benign (n = 26) and metastatic (n = 30) LN were analyzed with regard to clinical, laboratory and imaging parameters. Patients with LNM exhibited significantly larger short axis diameter (SAD) and long axis diameter (LAD) vs. patients with benign LN (median 22.5 vs. 14 mm, p < 0.001 and median 29.5 vs. 21 mm, p = 0.003, respectively). Furthermore, the presence of central necrosis and high maximal standardized uptake value (SUVmax) in FDG-PET-CT scans were significantly associated with LNM (60 vs. 11.5% of patients, p < 0.001 and median 8.59 vs. 3.96, p = 0.013, respectively). With systemic therapy, a slight median size regression over time was observed in both metastatic and benign LN. Serum LDH and CRP levels were significantly higher in patients with LNM (median 247 vs. 187.5U/L, p = 0.005 and 1.5 vs. 0.55 mg/dL, p = 0.039, respectively). This study shows significant associations between LNM and imaging features as well as laboratory parameters of STS patients. The largest SAD, SUVmax in FDG-PET-CT scan, the presence of central necrosis, and high serum LDH level are the most important parameters to distinguish benign from metastatic LNs.

[Current therapeutic standards in advanced soft tissue sarcomas]. / Neues zu Weichteilsarkomen.

Soft tissue sarcomas account for less than 1% of tumors in adults. With more than 80 different subtypes and often dismal prognosis, treatment of patients with soft tissue sarcomas is diagnostically and therapeutically complex. In patients with localized disease, surgery remains the mainstay of therapy. A multimodal approach consisting of neoadjuvant chemotherapy +/- regional hyperthermia may be suitable in patients with high-risk disease to maximize tumor shrinkage before surgery and to treat micrometastases. In patients with oligometastatic disease, local treatment options should be discussed within a specialized tumor board. In patients with disseminated metastatic disease, chemotherapy with anthracyclines remains the backbone of therapy. Immune checkpoint inhibitors have proven to be effective for patients with alveolar soft part sarcoma and targeted therapies with NTRK-inhibitors should be evaluated in patients with NTRK-fusions. This article focuses on current standards and developments in the treatment of soft tissue sarcomas.

[Aggressiveness and violence in daily ophthalmology practice: Descriptive analysis of a survey sent to residents and assistants in Grand Est and Bourgogne-Franche-Comté]. / Agressivité et violence au cours de l'exercice professionnel en ophtalmologie : analyse descriptive d'un questionnaire adressé aux internes et assistants des régions Grand Est, Bourgogne-Franche-Comté.

INTRODUCTION: The goal of this study was to estimate the prevalence of workplace violence in a population of young ophthalmologists in France and to characterize these situations. METHODS: We conducted an epidemiological descriptive, cross-sectional, multi-center study based on an anonymous questionnaire. We submitted a questionnaire to all ophthalmology residents and fellows (n=157) in the Grand Est and Bourgogne-Franche-Comté regions between December 2020 and March 2021. RESULTS: The overall response rate was 76.4% (n=120, 55% female and 45% male) of whom 81.6% reported having faced aggression at least once. For 50.9% of participants, aggression had occurred several times per year. These situations occurred during the first year of residency in 64.3% of cases. They mainly consisted of verbal aggression (98.8%) by a patient or their relatives (43.7% and 29.8%). The main complaints voiced by these individuals concerned the wait time (40%) and the feeling of lack of competence or improper medical care (26.8%). Fifty-seven percent of people who faced these situations thought about it for at least a week, and 20.4% of those exposed felt anxiety at work after the incident. CONCLUSION: We found high prevalence of verbal aggression in professional ophthalmology practice. Although these situations were mainly verbal aggression without significant consequences, they sometimes lead to anxiety in the aftermath. We should prepare medical students to manage them, through appropriate theoretical and practical training, such as medical simulation described in this article.

Common characteristics of shoulder injury related to vaccine administration following COVID-19 vaccination: a comprehensive systematic review.

BACKGROUND: The pathogenesis of shoulder injury related to vaccine administration (SIRVA) is incompletely understood, but it is postulated to be an immune-mediated inflammatory response to a vaccine antigen, leading to shoulder pain and dysfunction. The purpose of this investigation is to systematically review the literature related to SIRVA specifically after the COVID-19 vaccination by describing the diagnostic and clinical characteristics, diagnoses associated with SIRVA, and incidence between vaccine types. METHODS: A systematic review was performed to identify level I to IV studies and case descriptions of shoulder pain occurring after COVID-19 vaccination. To confirm that no studies were missing from the systematic review, references of studies from the initial search were scanned for additional relevant studies. RESULTS: A total of 22 studies, comprised of 81 patients, were identified meeting the inclusion/exclusion criteria. Reports were most commonly published from countries in Asia (53.1%; n = 43/81). The most commonly described vaccines were Oxford-AstraZeneca at 37.0% (n = 30/81) and Pfizer-BioNTech at 33.3% (n = 27/81). Symptoms occurred most commonly after at least 72 hours of administration (30.9%, n = 25/81). One hundred percent of patients (n = 81/81) described pain as an associated symptom and 90.1% of patients (n = 73/81) described multiple symptoms. The diagnostic modalities utilized to identify a specific pathology consisted of magnetic resonance imaging (55.6%; n = 45/81), ultrasound (28.4; n = 23/81), radiograph (25.9%; n = 21/81), and computed tomography (4.9%; 4/81). Nearly a third of patients (32.1%; n = 26/81) were diagnosed with bursitis, while 22 (27.2%) were diagnosed with adhesive capsulitis, 17 (21.0%) with either rotator cuff tear or tendinopathy, and 14 (17.3%) with polymyalgia rheumatica or polymyalgia rheumatica-like syndrome. The 2 most common treatment options were physical therapy (34.6%; n = 28/81) and nonsteroidal anti-inflammatory medications (33.3%; 27/81). The majority of SIRVA cases (52.1%; n = 38/73) completely resolved within a few weeks to months. CONCLUSION: Despite the limited quality and lack of large-scale studies, it is important for providers to recognize SIRVA as a potential risk factor as the number of patients receiving COVID-19 vaccinations and boosters continues to rise.

Higher success rate observed in reconstruction techniques of acute posterolateral corner knee injuries as compared to repair: an updated systematic review.

PURPOSE: There remains controversy regarding the optimal surgical treatment for acute complete (grade III) posterolateral corner (PLC) injuries. The purpose of this article is to systematically review the contemporary literature regarding surgical options and subsequent outcomes of acute grade III PLC injuries. METHODS: A systematic review was performed using the following search terms: posterolateral corner knee, posterolateral knee, posterolateral instability, multi-ligament knee, and knee dislocation. Inclusion criteria consisted of studies with level I-IV evidence, reporting on human patients with acute grade III PLC injuries undergoing operative management within 4 weeks from injury, with subjective and/or objective outcomes (including varus stress examinations or varus stress radiographs) reported at a minimum 2-year follow-up. Two investigators independently performed the search by sequentially screening articles. Accepted definitions of varus stability on examination or stress radiographs and revision surgery were used to determine success and failure of treatment. RESULTS: A total of 12 studies, consisting of 288 patients were included. Ten studies reported primary repair, while reconstruction techniques were reported in seven studies. Overall, 43% (n = 125/288) of injuries involved the PLC, ACL and PCL. Staged reconstruction was reported in 25% (n = 3/12) of studies. The Lysholm score was the most commonly reported outcome measure. An overall failure rate of 12.4% (n = 35/282) was observed. Surgical failure was significantly higher in patients undergoing repair (21.9%; n = 21/96) compared to reconstruction (7.1%; n = 6/84) (p = 0.0058). Return to sport was greater in patients undergoing reconstruction (100%; n = 22/22) compared to repair (94%; n = 48/51) (n.s). The most common post-operative complication was arthrofibrosis requiring manipulation under anesthesia (8.7%; n = 25/288). A total of 3.8% (n = 11/288) of patients underwent revision PLC reconstruction. CONCLUSION: There remains substantial heterogeneity in the surgical techniques of acute, grade III PLC injuries with an overall failure rate of 12.4%. Failure rates were significantly lower, and return to sport rates higher in patients undergoing PLC reconstruction compared to repair. The most common postoperative complication was arthrofibrosis requiring manipulation under anesthesia. LEVEL OF EVIDENCE: Level IV.

Implementing precision oncology for sarcoma patients: the CCCLMUmolecular tumor board experience.

PURPOSE: Due to poor outcomes and limited treatment options, patients with advanced bone and soft tissue sarcomas (BS/STS) may undergo comprehensive molecular profiling of tumor samples to identify possible therapeutic targets. The aim of this study was to determine the impact of routine molecular profiling in the setting of a dedicated precision oncology program in patients with BS/STS in a German large-volume sarcoma center. METHODS: 92 BS/STS patients who received comprehensive genomic profiling (CGP) and were subsequently discussed in our molecular tumor board (MTB) between 2016 and 2022 were included. Patient records were retrospectively reviewed, and the clinical impact of NGS-related findings was analyzed. RESULTS: 89.1% of patients had received at least one treatment line before NGS testing. At least one molecular alteration was found in 71 patients (82.6%). The most common alterations were mutations in TP53 (23.3% of patients), followed by PIK3CA and MDM2 mutations (9.3% each). Druggable alterations were identified, and treatment recommended in 32 patients (37.2%). Of those patients with actionable alterations, ten patients (31.2%) received personalized treatment and six patients did benefit from molecular-based therapy in terms of a progression-free survival ratio (PFSr) > 1.3. CONCLUSION: Our single-center experience shows an increasing uptake of next-generation sequencing (NGS) and highlights current challenges of implementing precision oncology in the management of patients with BS/STS. A relevant number of patients were diagnosed with clinically actionable alterations. Our results highlight the potential benefit of NGS in patients with rare cancers and currently limited therapeutic options.

Radiofrequency-Based Chondroplasty Creates a Precise Area of Targeted Chondrocyte Death With Minimal Necrosis Outside the Target Zone: A Systematic Review.

Purpose: To systematically examine the effects of radiofrequency (RF) ablation or coblation (controlled ablation) on chondrocyte viability following knee chondroplasty in preclinical literature to determine the effectiveness and safety of RF-based techniques. Methods: A literature search was performed in September 2022 using PubMed and Scopus using the following search terms combined with Boolean operators: "chondroplasty," "radiofrequency," "thermal," "knee," "chondral defect," "articular cartilage," and "cartilage." The inclusion criteria consisted of preclinical studies examining the effect of RF ablation or coblation on chondrocytes during knee chondroplasty. Exclusion criteria consisted of studies reporting chondroplasty in joints other than the knee, clinical studies, in vitro studies using animal models, case reports, non-full-text articles, letters to editors, surveys, review articles, and abstracts. The following data were extracted from the included articles: author, year of publication, chondral defect location within the knee and chondral characteristics, RF probe characteristics, cartilage macroscopic description, microscopic chondrocyte description, and extracellular matrix characteristics. Results: A total of 17 articles, consisting of 811 cartilage specimens, were identified. The mean specimen age was 63.4 ± 6.0 (range, 37-89) years. Five studies used monopolar RF devices, 7 studies used bipolar RF devices, whereas 4 studies used both monopolar and bipolar RF devices. Time until cell death during ablation at any power was reported in 5 studies (n = 351 specimens), with a mean time to cell death of 54.4 seconds (mean range, 23.1-64) for bipolar RF and 56.3 seconds (mean range, 12.5-64) for monopolar RF devices. Chondrocyte cell death increased with increased wattage, while treatment time was positively correlated with deeper cell death. Conclusions: In this systematic review, histologic analysis demonstrated that RF-based chondroplasty creates a precise area of targeted chondrocyte death, with minimal evidence of necrosis outside the target zone. Caution must be exercised when performing RF-based chondroplasty due to the risk of cell death with increased application time and wattage. Clinical Relevance: Although RF ablation has demonstrated favorable results in preliminary trials, including smoother cartilage and less damage to the surrounding healthy tissue, the risks versus benefits of the procedure are largely unknown. Caution must be exercised when performing RF-based chondroplasty in the clinical setting due to the risk of cell death with increased application time and wattage.

TIM-3 Qualifies as a Potential Immunotherapeutic Target in Specific Subsets of Patients with High-Risk Soft Tissue Sarcomas (HR-STS).

(1) Background: The expression of T cell immunoglobulin and mucin domain-containing protein 3 (TIM-3), an immune checkpoint receptor on T cells, has been associated with dismal outcomes and advanced tumor stages in various solid tumors. The blockade of TIM-3 is currently under examination in several clinical trials. This study examines TIM-3 expression in high-risk soft tissue sarcomas (HR-STS). (2) Methods: Tumor cell expression of TIM-3 on protein level was analyzed in pre-treatment biopsies of patients with HR-STS. TIM-3 expression was correlated with clinicopathological parameters including tumor-infiltrating lymphocyte (TIL) counts, programmed cell death 1 (PD-1) and programmed cell death ligand 1 (PDL-1) expression in patients with HR-STS. Survival dependent on the expression of TIM-3 was analyzed. (3) Results: TIM-3 expression was observed in 101 (56%) out of 179 pre-treatment biopsies of patients with HR-STS. TIM-3 expression was significantly more often observed in undifferentiated pleomorphic sarcomas (UPS) compared to other histological subtypes (p < 0.001), high TIL counts (p < 0.001), and high PD-1 (p < 0.001) and PD-L1 expression (p < 0.001). TIM-3 expression did not have a prognostic impact on survival in patients with HR-STS. (4) Conclusions: This is the first study to demonstrate a significant tumor cell expression of TIM-3 in specific subsets of patients with HR-STS. TIM-3 qualifies as a potential immunotherapeutic target in HR-STS.

Evaluation of Social Media and Online Utilization Among Members of the American Orthopaedic Society for Sports Medicine: Implications in Practice.

Background: Social media has the potential to act as an avenue for patient recruitment, patient and surgeon education, and expansion of the physician-patient relationship. Purpose: To evaluate the existing social media presence among members of the American Orthopaedic Society for Sports Medicine (AOSSM) to describe trends in different subgroups within the membership. Study Design: Cross-sectional study. Methods: The AOSSM database was queried for a complete membership list. Members were excluded from analysis if they were not orthopaedic sports medicine surgeons practicing in the United States. Demographic characteristics, online media profiles, and levels of online presence were evaluated, and an online media presence score was calculated. Bivariate analysis was performed to compare demographic variables and levels of online presence. Results: A total of 2870 surgeons were included in the analysis. LinkedIn was the most used platform (56%), while YouTube was the least used (10%). Surgeons in academic practice had a significantly greater overall social media presence than their private practice counterparts. Female surgeons had a more significant active online presence on Twitter, Instagram, and Facebook than male surgeons. Surgeons practicing in the Northeast had a greater social media presence than those in any other United States region, and surgeons in the earlier stages of practice (0-14 years) were more likely to utilize social media than their more senior colleagues (≥15 years of practice). On multivariate analysis, surgeons in the earlier stages of practice were more likely to have active Twitter, Instagram, and Facebook accounts, and female surgeons were more likely to have an active Facebook account. Additionally, multivariate analysis revealed that a greater number of ResearchGate publications were associated with male sex and having an academic practice. Comparatively, active Twitter and Instagram use was associated with having an academic practice. Conclusion: The most used platform in this surgeon population was LinkedIn. Orthopaedic surgeons in academic practice, female surgeons, those early in their career, and those practicing in the Northeast highlighted a subset of the sports medicine community who were more likely to have an active online presence compared to the rest of the AOSSM.

Single-stage autologous cartilage repair results in positive patient-reported outcomes for chondral lesions of the knee: a systematic review.

AIM: This article aims to perform a systematic review of the clinical literature regarding the efficacy of single-stage autologous cartilage repair. METHODS: A systematic review of the literature was performed using PubMed, Scopus, Web of Science, and the Cochrane Library. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. RESULTS: Twelve studies were identified; however, due to overlapping patient cohorts, nine studies were included for data extraction and analysis. Six studies applied minced cartilage, while three studies utilized enzymatically processed cartilage. Two authorship groups described single-stage techniques that exclusively utilized cartilage from the debrided lesion rim, while the remaining groups either utilized healthy cartilage or combined healthy cartilage with cartilage debrided from lesion rim. Among the included techniques, scaffold augments were used in four studies, and three studies implemented bone autograft augmentation. When summarizing patient reported outcome measures for the included studies, single-stage autologous cartilage repair demonstrated an average improvement ranging from 18.7 â€‹± â€‹5.3 to 30.0 â€‹± â€‹8.0 amongst the Knee Injury and Osteoarthritis Outcome Scores subsections, 24.3 â€‹± â€‹10.5 for the International Knee Documentation Committee subjective score, and 41.0 â€‹± â€‹10.0 for Visual Analogue Scale-Pain. CONCLUSION: Single-stage autologous cartilage repair is a promising technique with positive clinical data to date. The current study highlights the overall improvement in patient reported outcomes after repair for chondral defects to the knee with average follow-up ranging from 12 to 201 months and also the heterogeneity and variability of the single-stage surgical technique. Further discussion on the standardization of practices for a cost-effective single-stage augmented autologous cartilage technique is needed. In the future, a well-designed randomized controlled trial is needed to explore the efficacy of this therapeutic modality relative to established intervention. LEVEL OF EVIDENCE: Systematic review; Level IV.

Revision Lateral Femoral Condyle Osteochondral Allograft Transplantation With the Snowman Technique After Failed Previous Oblong Osteochondral Allograft.

Osteochondral allograft transplantation provides components of both cartilage and subchondral bone and can be used in large and multifocal defects where autologous procedures are limited by donor-site morbidity. Osteochondral allograft transplantation is particularly appealing in the management of failed cartilage repair, as larger defects and subchondral bone involvement are often present, and the use of multiple overlapping plugs might be considered. The described technique provides our preoperative workup and reproducible surgical approach for patients who have undergone previous osteochondral transplantation with graft failure and are young, active patients who would not be otherwise suited for a knee arthroplasty procedure.

Spanish-Speaking Patients Have Limited Access Scheduling Outpatient Orthopaedic Appointments Compared With English-Speaking Patients Across the United States.

Purpose: To evaluate whether Spanish-speaking patients can obtain appointments to outpatient orthopaedic surgery clinics across the United States at a similar rate as English-speaking patients and to examine the language interpretation services available at those clinics. Methods: Orthopaedic offices nationwide were called by a bilingual investigator to request an appointment with a pre-established script. The investigators called in English asking for an appointment for an English-speaking patient (English-English), called in English requesting an appointment for a Spanish-speaking patient (English-Spanish), and called in Spanish asking for an appointment for a Spanish-speaking patient (Spanish-Spanish) in a random order. During each call whether an appointment was given, the number of days to the offered appointment, the mechanism of interpretation available in clinic, and whether the patient's citizenship or insurance information was requested was collected. Results: A total of 78 clinics included in the analysis. There was a statistically significant decrease in access to scheduling an orthopaedic appointment in the Spanish-Spanish group (26.3%) compared with English-English (61.3%) or English-Spanish (58.8%) groups (P < .001). There was no significant difference in access to appointment between rural and urban areas. Patients in the Spanish-Spanish group who made an appointment were offered in-person interpretation 55% of the time. There was no statistically significant difference in time from call to offered appointment or the request for citizenship status between the 3 groups. Conclusions: This study detected a considerable disparity regarding access to orthopaedic clinics nationwide in the individuals who called to establish an appointment in Spanish. Patients in the Spanish-Spanish group were able to make an appointment less often but had in-person interpreters available for interpretation services. Clinical Relevance: With a large Spanish-speaking population in the United States, it is important to understand how lack of proficiency with the English language may affect access to orthopaedic care. This study uncovers variables associated with difficulties scheduling appointments for Spanish-speaking patients.

Location and motion of vaginal pessaries in situ in women with successful and unsuccessful pessary treatment for pelvic organ prolapse.

INTRODUCTION AND HYPOTHESIS: The objective was to compare the location and motion of pessaries between women with pelvic organ prolapse (POP) with a successful (fitting) and unsuccessful (non-fitting) pessary treatment on dynamic magnetic resonance imaging (dMRI). METHODS: A cross-sectional exploratory study of 15 women who underwent a mid-sagittal dMRI of the pelvic floor at rest, during contraction and during Valsalva with three different types of pessaries. The coordinates of the pessaries cross section, inferior pubic point (IPP) and sacrococcygeal junction (SCJ) were obtained and the location (position, orientation) and the motion (translation and rotation) were calculated. Differences between the groups and between the pessaries within the groups were compared. RESULTS: Nine women with a fitting pessary and 6 women with a non-fitting pessary were selected. In the non-fitting group, the pessaries were positioned more caudally and rotated more in clockwise direction and descended more, but not significantly, during Valsalva compared with the fitting group. The Falk pessary was positioned more anteriorly in the fitting group and more cranially in the non-fitting group compared with the ring and ring with support pessary. CONCLUSIONS: A non-fitting pessary was positioned more caudally at rest; on Valsalva, it rotated more clockwise and moved more caudally, suggesting that the dynamic characteristics of the pessary might play an important role in its effectiveness. Findings of this study serve as a basis for the development of new pessary designs.

Study Quality and Patient Inclusion in Geriatric Orthopaedic Trauma Research: A Scoping Review.

OBJECTIVES: To evaluate the quality of evidence published in geriatric traumatology, to investigate how many studies include patients with cognitive impairment, and to investigate which methods are used to determine cognitive impairment. DATA SOURCES: A search was conducted in PubMed for all publications in English in 154 selected journals between 01/01/2017 and 01/01/2020. STUDY SELECTION: Clinical studies investigating patients 65 years of age and older with fractures in the appendicular skeleton or pelvis were included. DATA EXTRACTION: Two independent reviewers performed full-text screening and data extraction for all articles. DATA SYNTHESIS: A comparative analysis was performed for prospective cohort studies and RCTs. The results are discussed in a narrative review. CONCLUSIONS: A total of 2711 publications were screened for eligibility, and after exclusion, a total of 723 articles were included. There is a focus on retrospective studies investigating mortality and complications. Studies are often small in sample size, and there are relatively few prospective studies, RCT studies, patient-reported outcomes, and quality of life. Patients with cognitive impairment are selectively excluded from clinical studies, and no consensus exists on how cognitive impairment is diagnosed. This review identified pitfalls and provides recommendations to navigate these issues for future studies. Many studies exclude cognitively impaired patients, which may result in selection bias and inability to extrapolate results. The lack of use of objective measures to define cognitive impairment and lack appropriate outcome measures for the cognitively impaired is an important issue that needs to be addressed in future research.

Patient-specific instrumentation for medial opening wedge high tibial osteotomies in the management of medial compartment osteoarthritis yields high accuracy and low complication rates: A systematic review.

IMPORTANCE: There has been growing interest in the use of patient-specific instrumentation (PSI) to maximise accuracy and minimise the risk of major complications for medial opening-wedge high tibial osteotomies (MOW-HTOs). Numerous studies have reported the efficacy and safety of implementing this technology into clinical practice, yet no systematic review summarising the clinical literature on PSI for MOW-HTOs has been performed to date. AIM: The aim of this investigation was to perform a systematic review summarising the evidence surrounding the use of PSI for MOW-HTOs in the management of medial compartment osteoarthritis. EVIDENCE REVIEW: PubMed, Scopus, and the Cochrane Library were queried in October 2021 for studies that used PSI for MOW-HTOs when managing medial compartment knee osteoarthritis. Primary outcomes included accuracy in coronal plane correction (mechanical medial proximal tibial angle), sagittal plane correction (posterior tibial slope), and mechanical axis correction (hip-knee-ankle angle [HKA], mechanical femorotibial angle, and weight-bearing line). Accuracy was defined as error between post-operative measurements relative to the planned pre-operative correction. A secondary outcome was the incidence of major complications. FINDINGS: This review included eight different techniques among the 14 included studies. There was a weighted mean error of 0.5° (range: 0.1°-1.3°) for the mechanical medial proximal tibial angle, 0.6° (range: 0.3°-2.7°) for the posterior tibial slope, and 0.8° (range: 0.1°-1.0°) for the hip-knee-ankle angle. Four studies compared the correctional error of the mechanical axis between conventional techniques and PSI techniques. The comparative difference between the two techniques favoured the use of PSI for MOW-HTOs (standardised mean difference â€‹= â€‹0.52; 95% confidence interval, 0.16 to 0.87; p â€‹= â€‹0.004). Among the 14 studies evaluated, four studies explicitly reported no major complications, while five studies reported a non-zero incidence of major complications. Among these nine studies, the weighted mean major complication rate was 7.1% (range: 0.0-13.0%). CONCLUSIONS AND RELEVANCE: The findings of this present systematic review suggest that the use of PSI for MOW-HTOs leads to high accuracy relative to the planned corrections in the coronal plane, sagittal plane, and mechanical axis. Furthermore, these findings would suggest there is a low risk of major complications when implementing PSI for MOW-HTOs. LEVEL OF EVIDENCE: Systematic review; IV.

Patients With Femoroacetabular Impingement Obtain Information From Low-Quality Sources Online and Are Most Interested in Conservative Treatment and Expected Recovery.

Purpose: To investigate the type of questions patients undergoing hip arthroscopy for femoroacetabular impingement (FAI) are searching online and determine the type and quality of the online sources from the top results to each query by the "people also ask" Google algorithm. Methods: Three search strings pertaining to FAI were carried out through Google. The webpage information was manually collected from the "People also ask" Google algorithm. Questions were categorized using Rothwell's classification method. Each website was assessed using Journal of the American Medical Association Benchmark Criteria for source quality. Results: A total of 286 unique questions were collected with their associated webpages. The most common questions included: "How do you treat femoroacetabular impingement and labral tears without surgery?" "What is the recovery process after hip arthroscopy and are there limitations after surgery?" and "How do you diagnose hip impingement and differentiate from other causes of hip pain?" The Rothwell Classification of questions were fact (43.4%), policy (34.3%), and value (20.6%). The most common webpage categories were Medical Practice (30.4%), Academic (25.8%), and Commercial (20.6%). The most common subcategories were Indications/Management (29.7%) and Pain (13.6%). Government websites had the highest average Journal of the American Medical Association score (3.42), whereas Single Surgeon Practice websites had the lowest (1.35). Conclusions: Commonly asked questions on Google regarding FAI and labral tears pertain to the indications and management of pathology as well as pain control and restrictions in activity. The majority of information is provided by medical practice, academic, and commercial sources, which have highly variable academic transparency. Clinical Relevance: By better understanding which questions patients ask online, surgeons can personalize patient education and enhance patient satisfaction and treatment outcomes after hip arthroscopy.
