Observational Study
Key factors influencing clinical and functional outcomes in extracapsular proximal femur fractures: the role of early weight-bearing - one-year follow-up cohort of 495 patients.
Aim To establish a correlation between immediate post-surgical weight bearing in extracapsular hip fractures and final functional outcome as well as to study the correlation between immediate post-surgical weight bearing and morbidity and mortality during the first year. Methods Retrospective observational cohort study including 495 consecutive patients ≥75 years old operated of extracapsular proximal femur fracture. Medical records were reviewed and information of demographic data, radiological evolution, time to weight-bearing, mortality rate, medical and surgical complications and final ambulation status were recorded. ⋯ Despite mortality rate was lower in patients with immediate weight bearing (21%) compared with delayed weight bearing (21.4%), the difference was not statistically significant (p=0.9). Conclusion Immediate weight bearing was associated with shorter hospital stay and fewer medical complications, improving functional outcome. Also, no correlation was found between immediate weight bearing and increased surgical complications or mortality rate during first year after surgery.

Cage subsidence is a known complication of spinal fusion. Various aspects of cage design have been investigated for their influence on cage subsidence, whereas the potential contribution of graft material to load sharing is often overlooked. We aimed to determine whether graft in the aperture affects endplate pressure distribution. ⋯ Graft choice plays a role in reducing peak endplate pressures. This finding is relevant to implant subsidence, as well as graft loading and remodeling.

Global varus malalignment increase from double-leg to single-leg stance due to intra-articular changes.
Preoperatively planned correction for tibial osteotomy surgery is usually based on weightbearing long-leg Xrays, while the surgery is performed in a supine non-weightbearing position. The purpose of this study was to assess the differences in lower limb alignment in three different weightbearing conditions: supine position, double-leg (DL) stance and single-sleg (SL) stance prior to performing a medial opening wedge high tibial osteotomy (MOWHTO) for varus malalignment. The hypothesis of this study was that progressive limb-loading would lead to an increased preoperative varus deformity. ⋯ III, retrospective comparative study.

Two-year clinical results of a novel load redistribution device for the treatment of medial knee OA.
A potential method to relieve the pain from medial osteoarthritis of the knee is to offload the medial compartment. The Latella™ Knee Implant is a novel device designed to offload the medial compartment. The objective of the Cotera-1 study was to evaluate the preliminary safety and feasibility of the Latella implant to treat patients with medial OA of the knee, by a 2-year follow-up of a prospective multicenter feasibility study (Cotera-1) performed in the Netherlands and UK METHODS: In this first-in-man study, 11 participants received the Latella implant and were followed for 2 years, documenting physician assessment, Patient-Reported Outcome (PRO) scoring (KOOS, IKDC, Kujala, SF-36); Patient Global Assessment (PGA), radiographic analysis and MRI analysis, complications, reoperation rate and hip-knee-ankle axis. ⋯ II.

Comparison of two reinforcement rings for primary total hip arthroplasty addressing displaced acetabular fractures: a biomechanical analysis.
Aim of this study was to biomechanically compare two different acetabular cup fixation constructs in terms of fracture fixation for displaced acetabular fractures involving the anterior column with hemitransverse fracture under partial and full weight-bearing conditions. ⋯ The presented acetabulum roof-reinforcement plate (ARRP) provides stable conditions at the acetabular component with adequate stabilization of a displaced acetabular fracture.
