Does sex and region affect the patella position? A multi-center study of 2000 cases - Archives of Orthopaedic and Trauma Surgery

As patella height can affect the outcome of total knee arthroplasty (TKA) in a number of ways, this study aimed to investigate whether factors such as region, sex and age play a role in causing differences in patella height. Methods: Between the 1st of March and the 31st of December 2022, 2000 patients from 7 different countries (Turkey, Saudi Arabia, Germany, Austria, Italy, Spain, and the United Kingdom) awaiting elective TKA were enrolled in this study. Lateral radiographs of the knee with the femoral condyles fully overlapped were used to measure the Insall-Salvati index. The patella height measurements were then correlated with age, sex and region to see if there were any patterns of distribution. Results From ten different hospitals across seven countries, 2,000 patients were collected. Approximately, 50% of the groups were female and 50% were male with a median age at surgery of 59 years (± 20 years). There were no significant differences in patella position based on age, region or sex between the different study populations, although there were significant differences between patients from different countries. Conclusion: Patella height showed significant variability within our patient cohort, even between different populations within the same country of origin. However, it should be noted that age, sex and country of origin do not appear to influence patella height in the preoperative planning of knee surgery.

Do age, gender, and region affect tibial slope? A multi-center study - Archives of Orthopaedic and Trauma Surgery

Introduction: Tibial slope is a parameter that is important to recognize in knee kinematics and knee surgery. A very wide range of values governing posterior tibial slope exist in the literature. This study is based on the hypothesis that age, gender and region may have an effect on the tibial slope. Materials and methods: A total of 1800 lateral knee radiographies from five different countries [Turkey, Germany, Italy, Spain, and the United Kingdom (UK)] were utilized to measure the native posterior tibial slope. Participants were categorized in deciles with each decade of age after 40 years determined as a separate age group. Accordingly, four different age categories were formed in total, namely, the 40- to 49-, 50- to 59-, 60–69, and 70- to 79-year-old groups. Patients with severe knee osteoarthritis, those with a history of arthroscopic and open surgery around the knee, and those with severe morbid obesity and those outside the specified age group were excluded from the study. The angle between the line tangential to the medial tibial plateau and the proximal anatomical axis of the tibia was measured. Results The tibial slope values of both males and females in the Turkish population were found to be higher than those in other populations. It was observed that tibial slope values increased with age in females in all populations, except for those in the Spanish and UK populations. In the male population, it was found that tibial slope values increased with age in all populations except in the Spanish population. Conclusions: Region, age, and gender affect tibial slope in different populations in various ways. Our study shows that the region an individual lives in and living conditions affect the tibial slope.

Acute Fracture Neck of Femur Among Inpatients: Severe Injuries Which Need to be Taken Seriously

Forty patients (mean age, 82.6 years) sustained an injury while being treated in hospital for an unrelated cause between January 2012 and June 2013. Case notes and incident reports were analyzed retrospectively. Results Thirty-three (82.5%) of 40 patients had at least 1 fall screen on admission, with 27 patients (81.8%) identified as a fall risk. Fifteen patients (37.5%) had at least one fall before sustaining a FNOF. Fifteen falls occurred between midnight—0500 hours and only 4 falls were witnessed. Thirty-nine of 40 falls were reported, but none were rated as “severe” injuries. Twenty-eight (71.8%) of 39 patients had a root cause analysis performed for the injury, but only 10 root cause analyses (25.6%) produced an action plan. Fifty percent of patients died within 1 year of injury. Conclusion Accurate fall risk assessments and adequate patient supervision are essential to minimize risks of falls, as the inpatient FNOF is linked to a higher mortality rate than patients injured in the community. A standardized method of analyzing such incidents and dissemination of the results of investigation are also required to reduce the risk of similar incidents from occurring within the hospital environment....
