Analysis of Trends in Orthopedic Knee Surgery—Key Findings on Total and Unicompartmental Knee Arthroplasty from a Leading Journal

Abstract

Purpose: This review examines the recent literature on total knee arthroplasty (TKA) and unicompartmental knee arthroplasty (UKA) published in the Knee Surgery Sports Traumatology and Arthroscopy (KSSTA) journal in 2023. The aim was to identify key research themes, advancements, and global contributions to knee surgery research. Methods: Articles published in KSSTA in 2023 were identified through a structured database search using the term “knee OR TKA OR UKA”. Inclusion criteria focused on primary studies, reviews, and case reports in English related to TKA or UKA. Data were extracted and synthesized thematically to analyze research trends and gaps. Results: The search yielded to 75 articles, 63 focused on TKA and 12 on UKA. Most contributions originated from Europe, followed by Asia and North America. Robotic-assisted TKA emerged as a significant advancement, enhancing surgical precision but requiring further validation through extended follow-up studies. Personalized implants showed potential for improved outcomes, though cost-effectiveness remains a concern. In UKA, slight overcorrection during alignment was associated with better functional results. Conclusions: The literature in the 2023 KSSTA highlights journal-specific trends and innovations in knee surgery. While techniques like robotic TKA and personalized implants are promising, further research is essential to standardize protocols and evaluate long-term impacts, emphasizing the need for sustained research efforts in knee orthopedics.
