Objective: To evaluate the early clinical results of total knee arthroplasty (TKA) with JOURNEY prosthesis.
Methods: From September 2006 to May 2007, TKA with JOURNEY prosthesis was used to treat 32 patients in ATOS Clinic, Germany. There were 21 males and 11 females, aged 40-84 years old (average 65.6 years old). The locations were left knee in 13 cases and right knee in 19 cases, including 5 cases of traumatic arthritis, 19 cases of osteoarthritis and 8 cases of rheumatoid arthritis. All patients had pain and limited range of motion (ROM) of knee. MRI scanning showed that cartilage and meniscus damaged in all cases. The disease course was 1 to 4 years (average 2.2 years). The CPM practice started 2 days after operation.
Results: The operative time was (75.0 +/- 21.7) minutes. The blood loss was (280 +/- 130) mL. All incision healed by first intention. Thirty-two patients were followed up 12 to 18 months (average 14.2 months). Hydrarthrosis occurred in 8 cases at 3-6 months postoperatively. Femur paraprosthetic fracture and implant dislocation occurred at 1 week and at 6 months in 2 cases, respectively. There were statistically significant differences in KSS score between preoperation and 3, 6, 12 months after operation (P < 0.05), between 3 months and 6, 12 months after operation (P < 0.05); there was no statistically significant difference in KSS score between 6 months and 12 months after operation (P > 0.05). There were statistically significant differences in pain score between preoperation and 3, 6, 12 months after operation (P < 0.05), and in ROM between 3 months and 6, 12 months after operation (P < 0.05). There was no statistically significant difference in ROM between preoperation and 3 months after operation (P > 0.05).
Conclusion: It is a simple way to TKA with JOURNEY prosthesis, which has a good results in early follow-up period.

Early Reinitiation of Obesity Pharmacotherapy Post Laparoscopic Sleeve Gastrectomy in Youth: A Retrospective Cohort Study.
Obes Surg

Division of Upper Gastrointestinal and General Surgery, Department of Surgery, Keck Medical Center of University of Southern California, Los Angeles, USA.
Background: Bariatric surgery is the most effective intervention for severe pediatric obesity, but a subset of youth experience suboptimal weight loss and/or recurrent weight gain. Early re-initiation of obesity pharmacotherapy postoperatively may improve outcomes, though this has not been evaluated in pediatric populations.
Methods: A retrospective cohort study at a tertiary care children's hospital evaluated the safety and efficacy of reintroducing obesity pharmacotherapy within six weeks after laparoscopic sleeve gastrectomy (LSG).
Presurgical anxiety and acute postsurgical pain predict worse chronic pain profiles after total knee/hip arthroplasty.

Introduction: Total joint arthroplasties generally achieve good outcomes, but chronic pain and disability are a significant burden after these interventions. Acknowledging relevant risk factors can inform preventive strategies. This study aimed to identify chronic pain profiles 6 months after arthroplasty using the ICD-11 (International Classification of Diseases) classification and to find pre and postsurgical predictors of these profiles.

Introduction: There is a lack of clinical evidence supporting the decision-making process between high tibial osteotomy (HTO) and unicomparmental knee arthroplasty (UKA) in gray zone indication, such as moderate medial osteoarthritis with moderate varus alignment. This study compared the outcomes between HTO and UKA in such cases and assessed the risk factor for not maintaining clinical improvements.
Materials And Methods: We retrospectively reviewed 65 opening-wedge HTOs and 55 UKAs with moderate medial osteoarthritis (Kellgren-Lawrence grade ≥ 3 and Ahlback grade < 3) and moderate varus alignment (5°< Hip-Knee-Ankle angle < 10°) over 3 years follow-up.

Background: In the case of end-stage hallux rigidus, first metatarsophalangeal (MTP) joint arthrodesis is the gold-standard and is traditionally performed via an open approach. However, complications such as nonunion have been reported to be as high as 30%. Recently, there have been reports demonstrating a percutaneous approach to be effective and safe.

Background: A giant encephalocele associated with Chiari malformation is a rare congenital anomaly from a cephalad neural tube defect. Early prenatal diagnosis and parental counseling are essential; as early surgical intervention can improve outcomes.
Methods: Between 2010 and 2023, twenty-seven newborns out of 43,815 delivered at our institution were diagnosed with encephaloceles, including seven cases of giant encephalocele associated with Chiari malformation type III.
