Abstract Background As revision surgeries of total hip arthroplasty are going to increase, success or failure of revised implants is a fundamental aspect in the orthopaedic field. Today, slight is known about the success rate of revised total hip arthroplasty when the femoral head is substituted on a retained stem. Question We wanted to investigate if the interposition of a stem taper adapter between the paired elements can influence this rate of success. Methods From a total of more than 1000 r...
Unicompartmental knee arthroplasty remains a challenge for orthopaedic surgeons because of its higher revision rate compare with the total knee arthroplasty. The hypothesis of this work is that the...

In biomechanics and orthopedics, finite element modelling allows simulating complex problems, and in the last few years, it has been widely used in many applications, also in the field of biomechanics and biotribology. As is known, one crucial point of FEM (finite element model) is the discretization of the physical domain, and this procedure is called meshing. A well-designed mesh is necessary in order to achieve accurate results with an acceptable computational effort. The aim of this work is ...

Structural analysis, based on the finite element method, and structural optimization, can help surgery planning or decrease the probability of fixator failure during bone healing. Structural optimization implies the creation of many finite element model instances, usually built using a computer-aided design (CAD) model of the bone-fixator assembly. The three most important features of such CAD models are: parameterization, robustness and bidirectional associativity with finite elements (FE) mode...
Abstract Purpose Although total knee arthroplasty is one of the most successful and consolidated surgical procedure, the infection rate is still elevate. To treat infected knee arthroplasties, in the past years was approached a procedure that involved the implantation of an antibiotic-loaded temporary spacer. This spacer helps maintain an appropriate soft tissue envelope and the patients are able to walk during the interim period. This study investigated the tribological behavior of antibiotic-i...

Purpose The effect of being obese on the long-term survival of total joint arthroplasty is persistently discussed. Considering only studies with large cohort of patients and meta-analysis, a high body mass index has been correlated with a higher incidence of complication but not univocally with a lower survival rate. In this study, we analyzed, retrospectively, the data of patients that received unicompartmental knee prostheses in order to examine if obesity has an effect on clinical outcomes.
Detailed knowledge about loading of the knee joint is essential for preclinical testing of total knee replacement. Direct measurement of joint reaction forces is generally not feasible in a clinical setting; non-invasive methods based on musculoskeletal modelling should therefore be considered as a valid alternative to the standards guidelines. The aim of this paper is to investigate the possibility of using knee joint forces calculated through musculoskeletal modelling software for developing a...

Abstract Background Total replacement of the knee joint is a well-established surgical procedure performed to relieve pain and to restore the functionality of a compromised knee. Nevertheless, wear is still one of the main issues affecting joint prostheses, causing loosening and, eventually, implants failure. Surface roughness of the implant has been found to influence the mechanisms for premature wear, having relevant influence on the tribological performance. Question Joint load distribution h...
Replacement surgery of hip joint consists of the substitution of the joint with an implant able to recreate the articulation functionality. This article aims to review the current state of the art of the biomaterials used for hip implants. Hip implants can be realized with different combination of materials, such as metals, ceramics and polymers. In this review, we analyze, from international literature, the specific characteristics required for biomaterials used in hip joint arthroplasty, i.e.,...
