    Abstract Background: Joint replacement is successful for end-stage osteopathy, with obesity linked to evaluated risk. But the impact of obesity on self-reported health and exercise capacity among joint replacement patients remains complex and requires investigation.
    Methods: This study utilizes data from the National Health and Nutrition Examination Survey (NHANES) to examine the relationship between obesity severity, demographic factors, medical comorbidities, and self-reported health status. The relationship between general health status and BMI was analyzed using multivariable regression, and further illustrated using a restricted cubic spline. Additionally, a bibliometric analysis and systemic review was done to frame the research within the broader context of existing knowledge and demographic specifics.
    Results: Analysis of NHANES data involving 327 joint replacement patients yielded intriguing insights. The difference in self-reported health between BMI groups did not achieve conventional statistical significance (P=0.06), and multivariable analysis showed that even severely obese patients did not exhibit significantly elevated risk of poor/fair self-reported health compared to normal weight subjects. Among severely obese individuals (BMI>40), 40.63% still rated their health positively. However, stratified analyses indicated that obesity correlated with negative health reports across gender, age, and education strata. Notably, physical functioning emerged as a robust predictor of self-reported health, with those reporting no walking difficulties having significantly lower odds of poor/fair health (Odds Ratio=0.37, P=0.01).
    Conclusion: The study highlights the need for healthcare providers to consider individual physical abilities and comorbidities alongside obesity severity when discussing treatment options with joint replacement patients. It supports tailored interventions and informed shared decision-making. Future research could explore effective weight management strategies for obese individuals undergoing joint replacement.

    Abstract Background: Modular reconstruction systems based on porous tantalum (PT) prosthetic components have been increasingly used for the treatment of complex acetabular bone defects in revision total hip arthroplasty (rTHA). We report a novel technique that applies a revision cup as a "super-augment" to form a "double-cup" construct for Paprosky type III defects.
    Method: A retrospective review was conducted on rTHA cases, comparing those treated with double-cup constructs (DC group, n = 48) to those treated with PT shells and augments (PT group, n = 48). All procedures were performed at the same institute between 2017 and 2022. Clinical outcome evaluation utilized the Harris Hip Score (HHS), Oxford Hip Score (OHS), and 36-Item Short Form Survey (SF-36). Preoperative and postoperative radiographic assessments measured hip center of rotation (COR) position and leg length discrepancy (LLD). Additionally, postoperative complications and implant survivorship were monitored during the follow-up period.
    Results: The clinical outcomes improved substantially in both groups, which showed no significant difference in HHS (P = 0.786), OHS (P = 0.570), and SF-36 (P = 0.691). Compared to the PT group, the reconstruction COR was significantly closer to the anatomic COR (vertical distance: 2.630 versus 7.355 mm, P = 0.0034; horizontal distance: 1.881 versus -6.413 mm, P < 0.0001) in Paprosky IIIB type defects. Additionally, postoperative LLD was less in the DC group (-8.252 versus -1.821 mm, P = 0.0008). Dislocation was the main complication in the DC group, and only one patient received re-revision due to repeated dislocation. The cumulative survival rate of the DC group (100%; 95% CI [confidence interval] 100) was better than the PT group (83.4%; 95% CI 70.5 to 98.6) when re-revisions for aseptic loosening were the endpoint (P = 0.046).
    Conclusions: The double-cup construct is a reliable revision technique for the reconstruction of Paprosky type III bone defects. Although dislocation remains challenging, the biomechanically superior restoration achieved by this technique lowers the risk of aseptic loosening.

    Abstract Background: The use of unicompartmental knee arthroplasty (UKA) in patients with preoperative synovitis is controversial. This study aimed to investigate the association between synovitis detected by magnetic resonance imaging (MRI) and prognosis after UKA.
    Methods: Synovitis was graded using the MRI Osteoarthritis Knee Score criteria based on preoperative MRI findings of 132 UKAs performed between June 2020 and August 2021. The Knee Society Knee Score (KS-KS) and the Knee Society Function Score were collected preoperatively and 1 year postoperatively. The relationship between synovitis and the changes in the Knee Society score was analyzed using logistic regression.
    Results: Univariate logistic regression showed that patients with higher preoperative synovitis scores (odds ratio (OR) = 1.925, 95% confidence interval (CI): 1.482-2.500, P < 0.001) had higher KS-KS changes. After adjusting for confounding variables, synovitis was proven to be an independent factor for KS-KS improvement after UKA in multivariate logistic regression (OR = 1.814, 95% CI: 1.354-2.430, P < 0.001). Before UKA, patients with synovitis had lower pain scores (PS) than patients without synovitis (95% CI: -17.159 - -11.160, t = -9.347, P < 0.001). There was no difference in PS between the two groups after UKA (95% CI: -6.559 - 0.345, t = -1.782, P = 0.077).
    Conclusions: Patients with synovitis can achieve good improvement of pain symptoms, and the efficacy is not inferior to that of non-synovitis patients after UKA.

    Abstract This study sought to provide a comprehensive assessment of the incidence of sports injuries among athletes participating in the Olympic Winter Games and to investigate contributing factors. We gathered injury data from athletes participating in the recent four Olympic Winter Games, incorporating details on the sports event, sex, injury location, and type. Through a meta-analysis, we calculated the injury incidence rates for each sport and examined the influence of sex and the type of sport on these incidence rates. Out of 11,197 registered athletes, we documented 1,304 sports injuries. The sports events with the highest injury rates were freestyle skiing, snowboarding, alpine skiing, bobsleigh, and ice hockey, with the most frequent injury locations being the knees, thoracic/lumbar/back regions, and the wrist/hand/fingers. Contusions, hematomas, and bruises were the most prevalent injuries, followed by strains (including muscle rupture, tearing, or tendon rupture) and sprains (covering dislocations, subluxations, and ligament ruptures). In the Olympic Winter Games, events such as freestyle skiing, snowboarding, alpine skiing, bobsleigh, and ice hockey pose a particularly high risk. Predominant injury sites include the knee, spine/back, and wrist and hand, with injuries ranging from contusions and hematomas to strains and sprains. For effective injury prevention, it is crucial to emphasize proper medical resource allocation, specialized training for medical personnel, and meticulous venue maintenance.

    Abstract Rapidly destructive arthrosis (RDA) is considered a rare and poorly diagnosed disease but is now seen more frequently in practice due to ageing populations. The most typical radiological features are flat femoral heads, absence of articular cartilage, subchondral bone destruction and signs of joint effusion. These features could be found on X-ray or magnetic resonance imaging (MRI). Surgeons should consider the presence of RDA when patients show rapid femoral head destruction. The purpose of this study is to review the distinct clinical features and successful treatments which may lead to the diagnosis and early handling of RDA. A comprehensive review of the literature was undertaken using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines with no language restrictions. Overall 23 publications with 17 detailed cases of RDA met the inclusion criteria. We found that the only prevalent factors associated with RDA were: (I) age greater than 60 years; (II) female gender; (III) presence of underlying systemic diseases such as rheumatoid arthritis, diabetes mellitus or systemic lupus erythematosus. Further studies should be conducted to clarify the histopathology and define the diagnosis as well as the treatment.

    Abstract Objective: To introduce a modified osteotomy method for proximal femur reconstruction (PFR) in total hip arthroplasty (THA) for high developmental dysplasia of the hip (DDH).
    Method: A retrospective study was performed in a series of 24 patients (26 hips) with Crowe III/IV DDH who underwent THA and simultaneous PFR. We used an animated video to illustrate and help understand the procedure for this technique. Patients were reviewed clinically and radiographically with an average follow-up of 31 months. The Harris hip score (HHS) was recorded preoperatively and at 3 and 12 months postoperatively.
    Results: All patients achieved primary bone union. No revision was needed up to the latest follow-up. One patient had a dislocation due to self-fall and received manual reduction under general anesthesia. No patient had intraoperative femoral fractures, sciatic nerve injury, or infection. The mean HHS improved from 33.48 ± 9.06 preoperatively to 84.61 ± 4.78 immediately after surgery and 90.84 ± 4.96 at 12 months.
    Conclusion: Proximal femur reconstruction is a simple and practical technique for femoral remolding during THA in patients with high DDH.

    Abstract Introduction: Although the advantages of total hip arthroplasty (THA) using the direct anterior approach (DAA) have been well documented, DAA in the supine position is limited by the difficulty in exposing the acetabulum and femur, which may result in implant malpositioning and intra-operative complications. Recent studies have reported that DAA-THA in the lateral position can achieve satisfactory clinical and radiographic outcomes. The aim of this study was to investigate the difference in implant alignment between two patient cohorts that underwent primary THA by DAA and the traditional posterolateral approach (PLA) in the lateral position.
    Methods: A total of 208 THAs (110 using DAA and 98 using PLA) were retrospectively analyzed.
    Results: The cup anteversion angle was closer to the target anteversion angle, and the accuracy of cup orientation was superior in the DAA group. A total of 82 (74.5%) DAA-THA and 56 (57.1%) PLA-THA cases showed successful inclination and anteversion angles (p = 0.008) of the implant. In addition, 90 (81.8%) DAA-THA and 67 (68.4%) PLA-THA cases had successful anteversion angle (p = 0.024). There was no significant difference between the two groups in terms of successful inclination angle (98 vs. 81, p = 0.181), as well as in the stem alignment in both coronal and sagittal planes.
    Conclusion: THA using DAA in the lateral position can achieve superior cup orientation compared to PLA while maintaining the stem alignment.
