Long-term functional success and robust implant survival in lateral unicompartmental knee arthroplasty: A case series with a mean follow-up of twenty two and a half years.

Purpose: Lateral unicompartmental knee arthroplasty (UKA) is an accepted treatment option in cases of end-stage lateral osteoarthritis. While lateral UKA has many proposed advantages compared to total knee arthroplasty, its technical challenges and relatively small number of cases make this an uncommon procedure. The aim of this study was to report the survivorship and functional outcomes beyond 20 years of follow-up of isolated UKA.

Artificial intelligence in knee arthroplasty: current concept of the available clinical applications.

Background: Artificial intelligence (AI) is defined as the study of algorithms that allow machines to reason and perform cognitive functions such as problem-solving, objects, images, word recognition, and decision-making. This study aimed to review the published articles and the comprehensive clinical relevance of AI-based tools used before, during, and after knee arthroplasty.

Methods: The search was conducted through PubMed, EMBASE, and MEDLINE databases from 2000 to 2021 using the 2009 Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol (PRISMA).

Safety of combined use of local anesthetic infiltration and reinfusion drains in total knee arthroplasty.

Injection of local anesthetic during total knee arthroplasty (TKA) has been shown to aid postoperative pain relief. Reinfusion drains have also proven useful in decreasing allogenic blood transfusion. Combined use carries the risk of reinfusion of local anesthetic from drainage bag.
