Abstract
In this editorial, we comment on the article by Toro et al published in the recent issue of World Journal of Orthopedics. This editorial review provides a comprehensive exploration of the landscape surrounding knee arthroplasty metallosis, focusing on key aspects ranging from the mechanisms influencing susceptibility to clinical implications and advanced treatment strategies. We elucidate the complex interplay of implant design, patient-specific variables, and wear-related processes contributing to metallosis. Furthermore, we seek to shed light on diagnostic challenges, the necessity of a multidisciplinary approach, and the imperative for vigilant implant surveillance. Uni-on-uni revision, as a targeted treatment modality, is discussed, highlighting its potential to address metallosis in unicompartmental knee arthroplasty (UKA). There is a need for heightened awareness among clinicians regarding the subtle presentations of metallosis, coupled with the limitations of traditional imaging techniques. Addressing metallosis requires a collaborative, multidisciplinary approach to effectively navigate the complexities associated with this complication. Furthermore, the review emphasizes the evolving paradigm of personalized care, with uni-on-uni revision emerging as a promising surgical solution. In conclusion, the editorial outlines the dynamic nature of knee arthroplasty metallosis and its multifaceted impact on clinical practice. It calls for ongoing collaboration, education, and integration of innovative solutions to enhance diagnostic accuracy, proactive management, and overall patient outcomes in the realm of UKA.
Core Tip: Metallosis is a rare but serious complication of unicompartmental knee arthroplasty. It is generally treated through surgical debridement and revision to a total knee arthroplasty. However, in the absence of critical signs of implant malpositioning, soft tissue impairment, or bone loss, it could be successfully resolved through surgical debridement and uni-on-uni revision.
