Objectives: This study aims to evaluate the accuracy and effectiveness of temporomandibular joint (TMJ) arthrocentesis using the three-dimensional (3D)-printed TMJ injection guide in cases of hemarthrosis caused by condyle fractures. Materials and Methods: A retrospective chart review was conducted for patients treated with the customized TMJ arthrocentesis guide to address hemarthrosis. Inclusion criteria included adults older than 18 years with condylar fractures not indicated for open reduction and internal fixation. The guide was fabricated using computed tomography or cone-beam computed tomography scans and 3D printing to control the degree and depth of the needle through the guide to aspirate hemarthrosis. Results: Six joints from five patients (average age 52.4 years) were treated using the guide. Post-procedural magnetic resonance imaging confirmed complete resolution of hemarthrosis in all cases. A representative case demonstrated successful outcomes with normal healing and no complications at 8 months post-procedure. Conclusion The customized TMJ injection guide, using ear-based reference points, significantly enhances the accuracy and safety of TMJ arthrocentesis. This innovation is expected to increase the accessibility and effectiveness of TMJ-related treatments for clinicians without specialized TMJ expertise.

The detrimental effects of hyperlipidemia on the healing of rotator cuff tears are well documented. The proposed underlying mechanisms for these effects include alterations in the extracellular matrix, inflammation, and oxidative stress, which hamper the reparative processes in the affected tendon tissues. Recent therapeutic strategies target these pathways, reflecting a growing body of research dedicated to mitigating these effects and promoting healing. This literature review aims to provide a comprehensive understanding of the pathophysiology underlying rotator cuff tears, examine the interplay between hyperlipidemia and rotator cuff tear healing, synthesize current knowledge on contributing biological mechanisms, and outline potential therapeutic interventions to optimize clinical management and treatment outcomes for patients.

Background: Living-donor liver transplantation (LDLT) is a viable alternative to deceased-donor liver transplantation. Enhanced recovery after surgery protocols that include early extubation offer short-term benefits; however, the effect of immediate extubation in the operating room (OR) on long-term outcomes in patients undergoing LDLT remains unknown. We hypothesized that immediate OR extubation is associated with improved long-term outcomes in patients undergoing LDLT. Methods: This retrospective cohort study included 205 patients who underwent LDLT. The patients were classified based on the extubation location as OREX (those extubated in the OR) or NOREX (those extubated in the intensive care unit [ICU]). The primary outcome was overall survival (OS), while secondary outcomes included ICU stay, hospital stay duration, and various postoperative outcomes. Results: Among the 205 patients, 98 (47.8%) underwent extubation in the OR after LDLT. Univariate analysis revealed that OR extubation did not significantly affect OS (hazard ratio [HR]: 0.50, 95% confidence interval [CI]: 0.24–1.05; P = 0.066). Furthermore, multivariate analysis revealed no statistically significant association between OR extubation and OS (HR: 0.79, 95% CI: 0.35–1.80; P = 0.580). However, OR extubation was significantly associated with a lower incidence of 30-day composite complications and shorter ICU and hospital stays. Multivariate analysis indicated that higher preoperative platelet counts, increased serum creatinine levels, and a longer surgery duration were associated with poorer OS. Conclusions Immediate OR extubation following LDLT surgery was associated with fewer 30-day composite complications and shorter ICU and hospital stays; however, it did not significantly improve OS compared with ICU extubation.

Objectives: Dextrose prolotherapy is one of the most promising minimally invasive interventions for temporomandibular disorder (TMD), particularly in refractory cases where other conservative treatments have failed. The purpose of this study was to demonstrate the efficacy of a new treatment, temporomandibular joint (TMJ) prolotherapy, in patients with TMD to alleviate symptoms. Materials and Methods: A retrospective analysis was conducted on TMD patients with chronic pain who did not respond to conventional treatments. TMJ prolotherapy was performed using hypertonic dextrose in the TMJ area, targeting the retrodiscal attachment tissue, anterior disc attachment tissue, lateral capsule, origin of the masseter muscle, and the stylomandibular ligament. Pain or discomfort intensity in the TMJ was evaluated using a numerical rating scale (NRS). Maximum mouth opening and subjective satisfaction were also analyzed. Results: Nineteen patients (6 males, 13 females, average age 43 years) participated in this study. All patients experienced pain improvement with a maximum of three prolotherapy sessions. The initial mean NRS was 5.7, which ultimately decreased to a final mean TMJ discomfort score of 1.7 postintervention. The patients’ maximum mouth opening increased from an initial 34.5 mm to 38.8 mm, and they reported positive satisfaction with the prolotherapy treatment. The clinical outcomes were positive regardless of main origin of TMD symptoms. Conclusion Hypertonic TMJ prolotherapy is an effective minimally invasive intervention for TMJ disorders with chronic pain.

Background and Objectives: The K-ELUVIA study aimed to investigate the clinical effectiveness and safety of Eluvia™, a polymer-coated, paclitaxel-eluting stent, for femoropopliteal artery disease using data from a prospective Korean multicenter registry. Methods: A total of 105 patients with femoropopliteal artery disease who received endovascular treatment (EVT) with Eluvia™ stents at 7 Korean sites were enrolled in a prospective cohort and followed for 2 years. The primary endpoint was the 2-year clinical patency. The secondary endpoint was 2-year freedom from clinically driven target lesion revascularization (TLR). Results: Mean patient age was 68.2±10.4 years, and most patients (82.7%) were male. Mean lesion length was 168.3±117.6 mm. Chronic total occlusion was found in 57.7% of patients.Trans-Atlantic Inter-Society Consensus for the Management of Peripheral Arterial Disease (TASC II) type C or D lesions were present in 46.1% of patients. Procedural success was achieved in 99.0% of patients. The clinical patency rate was 84.4% at 1 year after EVT and 76.3% at 2 years post-EVT. The freedom from TLR rate was 89.1% at 1 year after EVT and 79.1% at 2 years post-EVT. Chronic total occlusion (hazard ratio [HR], 3.53; 95% confidence interval [CI], 1.08–11.67; p=0.039) and smaller mean stent diameter (HR, 0.40; 95% CI, 0.16– 0.98; p=0.044) were identified as independent predictors of loss of clinical patency at 2 years. Conclusions The K-ELUVIA study demonstrated favorable 2-year clinical effectiveness and safety outcomes of Eluvia stent for femoropopliteal artery lesions in real-world practice.
