Studies have suggested increased local recurrence with diffuse TGCT, but few have assessed associations of local recurrence or erosions in TGCT of the knee. Our aim was to determine associations of erosions and local recurrence with patient and tumor characteristics in knee TGCT.Materials and methods: A retrospective chart review was performed on 53 patients with intraarticular, biopsy-proven TGCT of the knee diagnosed at our institution from December 2002 to December 2020. Bivariate analysis assessed the significance of associations between patient and tumor characteristics, surgical management, erosions, and local recurrence.Results: Of 53 patients with intra-articular, biopsy-proven TGCT of the knee, 24 (45%) patients had diffuse, intra-articular TGCT, and 7 (13%) patients had radiographic evidence of osseous erosions. In the diffuse, intra-articular subgroup, 12 (50%) patients had local recurrence, but 5 of 5 patients with erosions had local recurrence. Of the 19 patients with diffuse, intra-articular TGCT without erosion, 7 (37%) had local recurrence (P = .037). Of the 24 patients with diffuse, intra-articular TGCT, both those who had and did not have local recurrence had similar surgical treatment (75% arthroscopic, 25% open). The average recurrent-free survival was 936 days.Conclusion: Patients with diffuse, intra-articular TGCT of the knee with osseous erosions had a greater incidence of local recurrence than those without. Using erosions as a positive prognostic indicator for local recurrence may assist physicians in risk stratification of patients with diffuse, intra-articular TGCT.","PeriodicalId":19631,"journal":{"name":"Orthopedics","volume":"48 6","pages":"e238-e244"},"PeriodicalIF":1.2,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145669261","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}

Allowing immediate weight-bearing is gaining traction due to the benefits of early mobilization. This study compares postoperative complications of immediate weight-bearing as tolerated (WBAT) versus restricted weight-bearing (RWB) in distal femur fractures fixed with a lateral locking plate.Materials and methods: A retrospective analysis was conducted on all patients who underwent lateral locking plate fixation for distal femur fractures between October 2011 and April 2022 at four hospitals. Data collected included fracture characteristics, weight-bearing status, 30-day complications, and 1-year mortality. Radiographic outcomes including implant failure, malunion, nonunion, and time to union were assessed.Results: One hundred twenty-four patients met inclusion criteria. Immediate weight-bearing was permitted in 76 (61.3%). The WBAT group was older (83.2 vs 68.9 years, P < .001), had a lower body mass index (BMI) (28.1 vs 30.8, P = .037), and had fewer 30-day complications (7.9% vs 25.0%, P = .008). There was no difference in 30-day (6.3% vs 2.6%, P = .374) or 1-year mortality (14.6% vs 17.1%, .468).

Pain was measured with the Numeric Pain Rating Scale (NPRS, 0-10) and function with the Single Assessment Numeric Evaluation (SANE, 0-100). Demographic and clinical factors were collected via chart review.Results: A total of 918 patients completed the survey (53% female; mean age 63 years, range 18-97). Joints involved included elbows (106), wrists (335), and hands/fingers (667). Common diagnoses included arthritis (199), tendinopathy (273), and nerve-related conditions (160). Overall, 15% (135/918) reported prior CBD use, and 39% (53/135) perceived pain relief. CBD users were more likely to be female (65% vs 51%; P=0.003), to present with wrist pathology (44% vs 35%; P=0.038), and to have arthritis (36% vs 19%; P<0.001).

This study evaluated the impact of message timing and frequency on postoperative outcomes and patient-reported outcome measures (PROMs).Materials and methods: We retrospectively reviewed 9,353 primary TKAs performed at a single academic institution. Of these, 1,219 patients sent messages within 2 weeks of surgery (early), 507 sent messages between 2 and 8 weeks (late), and 7,627 did not message.Results: Patients who messaged within 2 weeks following surgery had shorter hospital length of stay (LOS) (41.2 vs 47.45 vs 53.40 hours, P < .001) and were more likely to be discharged home (99.5% vs 97.6% vs 96.8%, P < .001) compared to both late messengers and non-messengers. Patients who messaged late were more likely to experience a 90-day readmission surgery (3.2% vs 5.3% vs 3.3%, P = .05). Most messages were sent within 2 weeks (1.76 vs 1.48; P < .001). There was no difference in PROMs regardless of message timing, and there was no association between the number of messages sent and perioperative outcomes or PROMs.Conclusion: Older age and longer LOS were associated with less patient-initiated contact after TKA. Older patients may be less familiar with digital platforms and less likely to send messages. Early messaging may reflect heightened recognition of postoperative issues, enabling counseling or intervention and reducing readmissions.

The difference between leg lengths was assessed in the supine position by measuring the distance from the umbilicus to the medial malleolus when the participants used the right or left side of the table to lie on it. After the technique known as the Weber-Barstow maneuver was performed, leg lengths were found to be equal. Nine participants who still exhibited a length discrepancy even after the corrective maneuver were excluded from the study, as they had true LLD.Results: There was a significant relationship between the side of the examination table used by the participants and functional LLD. The participants who used the right side of the table to lie on it had a longer left leg, and vice versa. It was observed that taller participants exhibited a significantly greater functional LLD, whereas this difference was not significantly affected by sex.Conclusion: The side the patient uses to lie on the examination table may create functional LLD, which can be corrected with the Weber-Barstow maneuver.

This study provides updated national incidence rate estimates and characterizes trends in demographic and injury-related risk factors.Materials and methods: The National Electronic Injury Surveillance System was queried for all ankle sprain cases treated in US EDs from 2010 to 2024. Incidence rates were calculated per 1,000 person-years using US Census data, and relevant stratified analyses were conducted.Results: From 2010 to 2024, an estimated 7.4 million ankle sprains presented to US EDs, yielding an incidence of 1.53 per 1,000 person-years. Annual incidence declined from 2.12 in 2010 to 1.19 in 2024, with the lowest rate observed in 2020 (0.89) during the peak of the COVID-19 pandemic. Peak incidence occurred in adolescents aged 15 to 19 years (2.60 per 1,000), with over half of all sprains occurring in individuals aged 10 to 24.

We also modeled theoretical meetings held in locations including Chicago, IL, New Orleans, LA, and New York City, NY, as well as a hybrid meeting occurring across four regional hubs. Emissions for air travel were determined by computing emissions of direct flights to Las Vegas and the closest major airport for each state, using an emissions calculator. Attendees were assumed to use ground travel if they lived within a 250-mile radius of the meeting location. Travel by international attendees was also calculated. We also determined the geographic density of surgeons by state using data from the Association of American Medical Colleges workforce report.Results: The 2023 AAOS Annual Meeting was estimated to have generated 9,458 metric tons of travel-related CO2 equivalents compared with 7,073 (Chicago), 7,678 (New York City), and 7,396 (New Orleans) metric tons. The hybrid regional hub model, which excluded intercontinental travel, was estimated to generate only 1,368 metric tons.Conclusion: Total miles traveled had the most significant impact on carbon emissions.
