Abstract

Knee replacement surgery, or total knee arthroplasty (TKA), has emerged as a cornerstone of orthopedic treatment for severe knee disorders, primarily osteoarthritis. This commentary provides an in-depth overview of TKA, focusing on surgical indications, techniques, and advances in implant technology that contribute to improved patient outcomes. Evidence indicates that TKA effectively alleviates pain and enhances functionality, with patient satisfaction rates reaching 80-90% post-surgery. Complication rates remain low, typically between 2-5%, and modern implants show promising longevity, with survival rates exceeding 90% at ten years. The discussion highlights the importance of patient selection, education, and rehabilitation, as well as the impact of technological advancements such as minimally invasive techniques and robotic assistance. While TKA significantly improves quality of life, ongoing research is essential to refine surgical approaches and ensure equitable access to care. This overview underscores the critical role of TKA in orthopedic medicine and its potential for future enhancements in patient outcomes.
