An editorial on “Outcome of unicondylar knee arthroplasty vs total knee arthroplasty for early medial compartment arthritis: a randomized study”

Both total knee arthroplasty (TKA) and unicompartmental knee arthroplasty (UKA) are used to treat unicompartmental knee osteoarthrosis. Traditionally, TKA was believed to be a better option due to its durability, inclusive patient selection, and robust long-term data on its effectiveness to reduce pain and restore function (1). UKA was initially controversial. Studies conducted from the 1950s to the 1990s reported inconsistent results about the benefits of this surgical procedure (2).
