BackgroundVarious studies have described the restoration of the neutral mechanical alignment of the lower limb in total knee replacement (TKR) as a key factor of knee implant durability. Mechanical alignment of the knee requires that the tibial and femoral cuts are perpendicular to the mechanical axis of each bone in the coronal plane. ObjectivesThe aim of this study is to investigate mechanical knee alignment and the prevalence of constitutional varus knee among the Saudi population at a single tertiary center with no history of musculoskeletal abnormalities. MethodologyThis is a retrospective cross-sectional study involving patients with no musculoskeletal abnormality who had their lower limb X-ray Centigram using the universal viewer zero footprint system made between 2015 and 2021. The study took place at King Saud University Medical City. The X-rays were obtained from patients' electronic medical records retrospectively. A total of 728 knees of 370 males and 358 females were included in this study. ResultsThe results showed that 165 male knees (44.4%) and 218 female knees (60%) had constitutional varus alignment with the hip-knee-ankle (HKA) angle of ≤3° or less. The average HKA angle was smaller in males than in females: -3.69° versus -1.98°, respectively. ConclusionWe have identified variables and factors that can help surgeons detect the constitutional varus on a full leg radiograph preoperatively at the time of TKA, regardless of the osteoarthritic changes of the knee. We encourage the scientific community to look for causes and risk factors for developing constitutional varus.

Highlights Combined femoral arterial and nerve injury is rare in proximal femur fracture cases. As far as for our knowledge it is the first to be reported. We report a 42-year-old diagnosed with a left subtrochanteric femur fracture. Although promptly taken to surgery, leg amputation was necessary a week later. Blunt femoral injuries are associated with high morbidity and mortality rates.

Introductions: The median nerve's occasional or persistent compression or entrapment in the carpal tunnel from the wrist to the hand causes carpal tunnel syndrome (CTS). The main symptoms are pain, tingling, swelling, and loss of grip strength and function in the thumb, index finger, middle finger, and thumb of thumb. This study examined Saudi adults' awareness and understanding of Carpal Tunnel Syndrome and its link with demographics and chronic conditions. Material and Methods: This cross-sectional study examined adults' knowledge, attitudes, and practices regarding carpal tunnel syndrome from 2021 to 2022 in different Saudi Arabian regions. This study used a researcher-created questionnaire. In the awareness category, general public questions included CTS clinical aspects, etiology, and effects on daily life. Practice questions covered CTS preventive and chronic diseases. Volunteers were selected following informed consent. Result: 420 participants aged 34.8 ± 13.49 years. 280 (66.6%) were male, 140 (33.3%) females. 38 (9.04%) were non-Saudi workers, while 384 were Saudis. 235 (55.9%) individuals knew about wrist CTS and 161 (38.3%) about pain. 157 (37.3%) individuals experienced thumb tingling or numbness, while 117 and 142 agreed that CTS may produce thumb weakness (27.8%) and hand grip (35.2%). The older age group reported more thumb numbness or tingling than the other groups, although there was no statistical difference (p= 0.09). CTS was not associated with chronic disease; however, diabetes was the main comorbidity in all age groups (44; 45.3%), especially in the middle age group (21; 60%). 5.4% had CTS. CTS was rare during pregnancy (0.7%), however all age groups agreed that it could influence their employment and social life (p= 0.014 and < 0.00001). The average knowledge score was 43.3 ± 40.5, whereas the awareness score was 50.1 ± 44.2. These findings indicate that Saudis were aware of CTS clinical symptoms. Conclusion: The study examined Saudi adults' awareness and understanding of CTS and estimated the association between CTS and demographics and chronic conditions. The study found that adult CTS awareness and knowledge were sufficient and associated with age and quality of life. CTS awareness campaigns may lower risk and raise knowledge of prevention and treatment. People who work with discomfort or use computers for long periods of time without breaks are more prone to develop CTS. Larger research is needed to understand how physical exercise causes CTS.
