Should the early surgery threshold be moved to 72 h in over-85 patients with hip fracture? A single-center retrospective evaluation on 941 patients.
Aim of the study was to assess whether early surgery and other clinical and orthogeriatric parameters could affect mortality rate in hip fracture patients aged > 85. ⋯ In over-85 hip fracture patients, the threshold for early surgery might be moved to 72 h to allow patients pre-operative stabilization and medical optimization as intra-hospital and 30-day mortality rates remain significantly lower. Advanced age, male sex, number of comorbidities, pre-operative dependency in ADL, general anesthesia, length of hospitalization and transfer to other departments were significantly related to mortality rate.

Is new always better: comparison of the femoral neck system and the dynamic hip screw in the treatment of femoral neck fractures.
Hip fractures in the elderly population are common and the number of patients is rising. For young and geriatric patients with undisplaced fractures osteosynthesis is the primary type of treatment. The dynamic hip screw (DHS) is around for many years and proved its value especially in displaced fractures. Since 2018 the femoral neck system (FNS) is available as an alternative showing promising biomechanical results. The aim of this study is to evaluate clinical results of the FNS and compare it to the DHS. ⋯ FNS proved to be as reliable as DHS in all patients with hip fractures. Not the type of implant but blade positioning is still key to prevent implant failure. Still due to minimal invasive approach implant related infections and postoperative hematomas might have been prevented using the FNS.

Lateral unicompartmental knee arthroplasty (UKA) showed a lower risk of failure compared to medial unicompartmental knee arthroplasty in the Register of Prosthetic Orthopedic Implants (RIPO).
The present study aimed to investigate differences in survivorship between medial and lateral unicompartmental knee arthroplasty (UKA) by analyzing the data of an Italian regional registry. The hypothesis was that, according to recent literature, lateral implants have comparable survivorship with regard to the medial implants. ⋯ Level 3, therapeutic study.

Mobile bearing versus fixed bearing medial unicompartmental knee replacement: an independent two center matched-pairs analysis.
The aim of the present study was to compare clinical outcome between patients following fixed-bearing (FB) or mobile-bearing (MB) unicompartmental knee replacement (UKR) for antero-medial knee osteoarthrosis (OA) at two independent orthopedic centers. ⋯ Retrospective cohort study, Level IV.

Medial proximal tibial resorption after total knee arthroplasty according to the design of the cobalt chrome tibial baseplate.
A new tibial baseplate of the cobalt-chrome (CoCr) prosthesis has an enhanced design with additional cement pockets and undersurface with increased roughness compared with the original baseplate. This study aimed to compare the incidence of medial proximal tibial resorption (MPTR) in total knee arthroplasties (TKAs) with the original and new CoCr tibial baseplates. ⋯ III.
