A historical review reveals that McBride may have been the first to use a femoral head intramedullary stemmed hip implant. It had a threaded stem and limited use. Eicher may have been the first to develop and use the smooth intramedullary stemmed femoral implant with a calcar collar, which was the forerunner of implants used today. Moore subsequently developed the self-locking intramedullary stemmed femoral implant with a calcar collar. Shortly thereafter, Thompson introduced a similar prosthesis. These four surgeons pioneered the development of the intramedullary stemmed femoral head prosthesis, which has been a key contribution to modern hip reconstruction.

Introduction: Revision Total Knee Arthroplasty (RTKA) is complex, and induced bone loss might endanger implant fixation and joint stability. Intramedullary stems improve fixation throughout stress redistribution. The current study aims to compare the performance of short tibial stems with long tibial stems, investigating their intermediate-term radiographic and survival outcomes in RTKA.

Proximal femoral fractures are particularly common in older adults, and cases requiring conversion to total hip arthroplasty may arise because of treatment failure or osteoarthritis. Fractures around the distal screw removal holes can be problematic. This study aimed to analyze the relationship between stem length and femoral stress distribution to determine the optimal stem length.

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).

Introduction: Achieving stability in total knee arthroplasty (TKA) is crucial for long-term implant survival. In cases of severe deformity or ligament laxity, constrained implants may be required. Traditionally, increasing constraint involved intramedullary stems.

Article Synopsis
- Intramedullary stem extensions are added during revision total knee arthroplasty (TKA) to improve component fixation and longevity, often using hybrid fixation methods.
- The study involved a retrospective review of 153 patients re-evaluating the prevalence and impact of radiographic sclerotic lines at the bone-implant interface over a follow-up period of 15 years.
- Results showed that while 7.8% of patients had sclerotic lines, they did not significantly affect the rates of aseptic loosening, with a notable long-term survivorship rate of 94.8% free from failure due to loosening.
