The Etiology of Total Knee Arthroplasty Failure Influences on Improvement in Knee Function: A Follow-Up Study.
J Clin Med
December 2024
Department of Orthopedics, Klinik Penzing, Wiener Gesundheitsverbund, 1140 Vienna, Austria.
Outcomes following total knee arthroplasty (TKA) revisions are variable, and it is hypothesized that the underlying cause of primary TKA failure impacts postoperative outcomes. This study analyzes the results of TKA revisions seven years after surgery, in relation to the etiology of primary failure and other influencing factors. A previous study conducted in 2013 examined the same cohort of patients three months after revision surgery.

Background: In order to increase the stability of tibial component in total knee arthroplasty (TKA), intramedullary stem extensions (SE) have been developed. The aim of this systematic review and meta-analysis is to address the critical knowledge gap on post-operative outcomes and complications rate comparison between tibial component with SE compared to the tibial component standard configuration (SC) in primary cemented TKA.
Methods: We conducted a comprehensive search of online databases, including Pubmed, Embase, ISI Web of science, Cochrane Library, and Scopus, using the following MeSH terms, (total knee arthroplasty) OR (TKA) OR (total knee replacement) AND (Tibial stem) OR (stem extension) OR (long stem).
Contemporary Cementless Patellar Implant Survivorship: A Systematic Review and Meta-Analysis of 3005 Patellae.
J Knee Surg
January 2025
Orthopaedic Surgery, Mayo Clinic, Rochester, United States.
Introduction: Historically, cementless patellar implants were fraught with issues of fixation and polyethylene wear. However, contemporary cementless patellar implants incorporate modern technologies for implant design and offer the potential for improved biological fixation and longevity. As such, an evaluation of the performance of modern cementless patellae is needed.

J Clin Orthop Trauma

Loyola University Health System, Department of Orthopaedic Surgery and Rehabilitation, 2160 South First Avenue, 60153, Maywood, IL, USA.
Introduction: Mobile-bearing (MB) inserts, designed to minimize aseptic loosening and to reduce contact stresses leading to polyethylene wear, are an alternative to fixed-bearing (FB) inserts. Most studies have shown no significant difference between MB and FB constructs, and there is limited long-term data comparing the two constructs [1,2,3,4]. The purpose of this study was to report the outcomes of a randomized controlled trial comparing MB versus FB inserts on patients with minimum 20-year follow-up.

Hip Int
January 2025
Department of Orthopaedic Surgery, Hospital de Sant Pau (HSCSP), Barcelona, Spain.
Background: Survival at 25 years' follow-up for total hip arthroplasty (THA) has been reported at 5%-77%, with hydroxyapatite (HA) coating, due to its osteo-conductive properties, used to enhance implant fixation and survival. The progressive increase in life expectancy raises doubts regarding HA-coated THA survival and THA revision surgery risk. The aim of our study was to retrospectively analyse survival for primary uncemented fully HA-coated THA after 28 years' follow-up.
