Abstract： Objective： To analyze the general status of research on traditional Chinese medicine therapies after total knee arthroplasty （TKA） over the past two decades using CiteSpace. Methods：Literature on TKA postoperative treatment with traditional Chinese medicine therapy published from January 1， 2004 to December 31， 2025 and indexed in CNKI was retrieved. CiteSpace 6.4. R1 software was used to construct and visualize knowledge graph of authors，institutions，and keywords. Results：A total of 492 Chinese articles were included. The annual publication output showed phased growth since 2004， with a rapid increase from 2014 to 2021， peaking at 55 articles in 2021， and then stabilizing at approximately 39 articles per year thereafter， indicating that the field has entered a mature plateau stage. Guangzhou University of Chinese Medicine ranked first in output with 48 publications；SUN Songtao was the most prolific author， yet inter-institutional and cross-team collaboration networks remained relatively loose. Keyword co-occurrence， clustering， and burst detection revealed that research hotspots covered management of postoperative complications such as pain，swelling，and deep vein thrombosis，as well as internal-external traditional Chinese medicine therapies （e. g.， acupuncture/moxibustion， Chinese herbal fumigation-steaming， Taohong Siwu Decoction， Bazhen Decoction） and functional rehabilitation assessment， progressively extending toward mechanistic exploration and integration with the Enhanced Recovery After Surgery （ERAS） concept. Conclusion： Research on traditional Chinese medicine therapies for TKA postoperative care has reached a relatively stable developmental stage， with substantial accumulated findings. Current research focuses on postoperative complications， traditional Chinese medicine external therapies， and classical formula application， centering on clinical efficacy， functional recovery assessment，and peri-operative integrated Chinese medicine-western medicine management. Recent trends show a shift toward molecular mechanism investigation and deeper integration with ERAS principles.
