Multicenter Study Comparative StudyPeriprocedural clinical outcomes of revision hip arthroplasty: a multi-centric comparison of current strategies based on the NSQIP.
Recent projections suggest a substantial rise in demand for revision total hip arthroplasties, emphasizing the need for optimized perioperative care. Various revision techniques, such as isolated acetabular or femoral component revisions and total replacements, have garnered attention. Further research is needed to establish the most effective strategies for improving clinical outcomes. ⋯ The study's significance lies in its extensive patient cohort and multifaceted evaluation of revision strategies. Although consensus is lacking on single-component revisions, targeting the acetabulum component appears relatively safer. Continued research and individualized evaluations are crucial for refining revision strategies and optimizing outcomes in THA revisions.

Ilizarov fixator as salvage procedure after frustrating arthrodesis using intramedullary nailing - is there a chance of consolidation?
Arthrodesis of the tibiotalar and subtalar joints is a salvage procedure that has been used successfully for years. Treatment options include internal procedures and external procedures. Retrograde intramedullary nailing is considered a safe procedure with a high degree of stability and comfort. Nevertheless, there are cases in which this internal arthrodesis fails and another procedure must be considered. Ilizarov fixator treatment could be a solution for those patients in whom intramedullary nailing has failed. Even if it means another surgical revision - is it possible to finally achieve consolidation with this method? ⋯ If patients have undergone fusion of the tibiotalar and subtalar joints with a retrograde nail and this fails, it is difficult to achieve complete consolidation in the further course. A further attempt at arthrodesis using an Ilizarov fixator is possible, but the overall results are also poor. This procedure must therefore be seen as a last resort before amputation.

Acetabular retroversion and cam morphology are contributing risk factors for posterior hip dislocation independent of the trauma mechanism.
A high-energy trauma impact is generally considered the crucial factor causing native hip dislocation. However, femoroacetabular variations are assumed to contribute to low-energy posterior hip dislocations, especially in adolescent athletes. The study aimed to analyze the femoroacetabular morphology of adults who sustained traumatic posterior hip dislocations, comparing high-energy, sports-related, and low-energy trauma mechanisms. ⋯ Acetabular retroversion contributes to posterior hip dislocation in high-energy and sports-related trauma mechanisms and decreases the likelihood of sustaining concomitant fractures. Acetabular morphology was subordinate to causing hip dislocation following a low-energy impact. Increased alpha angles were identified as a risk factor contributing to posterior hip dislocations, regardless of the trauma mechanism.

International consensus-based ranking of definitions for poor response to primary total knee arthroplasty: a Delphi study.
This study aimed to rank definitions for measuring poor response one year after TKA, after assessing the face validity and feasibility of existing or newly proposed definitions. ⋯ This study identified seventeen potential definitions of poor response to TKA, offering valuable options for integration into quality assessment investigations. Remarkably, all identified definitions were patient-centered and none were clinician-centered. Single-item questions, capturing change from the patient's viewpoint, appear to be the most practicable format to assess response.

Comparative StudyClinical outcomes of unicompartmental knee arthroplasty and total knee arthroplasty in the same patient.
Osteoarthritis has become the predominant manifestation of arthritic conditions on a worldwide scale and serves as a significant instigator of pain, impairment, and increasing socio-economic strain on a global level. The ongoing discourse on the choice between total knee arthroplasty (TKA) and unicompartmental knee arthroplasty (UKA) for patients suffering from anterior medial osteoarthritis continues to ignite scholarly controversy. Our objective was to assess and compare the clinical outcomes of UKA and TKA within the same patient, hereby offering a novel perspective on this topic. ⋯ We found that UKA resulted in less physical strain, less postoperative inflammatory response, improved joint mobility, although with less effective lower limb force line correction compared to TKA. Many patients have shown a preference for UKA and express higher levels of satisfaction with the procedure.
