Comparative StudyMetal-backed versus all-poly tibia in the original cartier unicompartmental knee arthroplasty: outcomes and survivorship at long-term follow-up.
Unicompartmental knee arthroplasty (UKA) is a viable option for localized osteoarthritis (OA) or avascular osteonecrosis with several advantages over total knee arthroplasty (TKA). UKA implants may feature a tibial component either all-polyethylene (AP) or metal-backed (MB). This study aims to retrospectively compare the clinical outcomes and survivorship of 74 UKAs over 16 years, focusing on comparing the results and survivorship of MB versus AP tibial tray. ⋯ This research demonstrated outstanding implant durability and favorable outcomes during extended follow-up periods for both cohorts undergoing medial UKA utilizing the original fixed bearing Cartier design. The results regarding both survivorship and PROMs were equivalent the AP group and the MB group.

Comparative StudyDistinct knee phenotype variation: a comparative analysis of medial and lateral unicompartmental knee arthroplasty.
Lateral unicompartmental knee arthroplasty (UKA) is relatively less common than medial UKA. There has been no comparative analysis of the constitutional phenotypes of knees that underwent medial and lateral UKA. Therefore, this study aimed to compare the Coronal Plane Alignment of the Knee (CPAK) classification of knees that underwent medial and lateral UKA. Furthermore, the study analyzed whether CPAK phenotypes were maintained or altered after medial or lateral UKA. ⋯ Level III.

A modified Radiographic Union Score for Tibia (RUST) scoring system for patella fractures treated with osteosynthesis shows excellent intra und interobserver reliability.
Patellar fractures are rare at 1% incidence of all fractures. However, they can cause significant functional impairments due to the patella's role in knee joint extension. Current scoring systems lack objectivity in assessing patellar healing. This study aims to validate the Radiographic Union Score for Tibia (RUST) using biplanar radiographs for assessing surgically treated patellar fractures. ⋯ This study validated the Radiographic Union Score for Tibia (RUST) for evaluating bone healing in patellar fractures treated with osteosynthesis, demonstrating good intra- and interobserver reliability. The modified RUST can provide a standardized method for assessing healing in patellar fractures, benefiting both clinical practice and clinical trials.

Observational StudyMid-term outcomes after primary total hip arthroplasty with a cemented short stem in an elderly patient cohort.
The main objective of this prospective study was to assess clinical, radiographic and safety mid-term outcomes after THA with a short cemented stem in an elderly patient cohort. Moreover, the study aimed at investigating the mid-term survivorship of the implant and the incidence of complications. ⋯ NCT04987437.

Identifying predictors of nosocomial pneumonia in trauma patients admitted to a level-1 trauma center.
Nosocomial pneumonia is common in trauma patients and associated with an adverse prognosis. We recently externally validated and recalibrated an existing formula to predict nosocomial pneumonia risk. Identifying more potential predictors could aid in a more accurate prediction of nosocomial pneumonia risk in level-1 trauma patients. This study aims to identify predictors of nosocomial pneumonia in level-1 trauma patients available in the emergency department or shortly after, and examine their added predictive value to an existing prediction model by Croce. ⋯ Level III, prognostic/epidemiological.
