Abstract：BACKGROUND: With the rapid development of surgical techniques, unicompartmental knee arthroplasty has become an issue of concern in the treatment of osteoarthritis, which has achieved significant progress inreducing trauma and rapid rehabilitation.OBJECTIVE: To summarize the development history, curative effect of unicompartmental knee arthroplasty, and the research progress of lateral unicompartmental knee arthroplasty aided with computer navigation or robot system, thus providing reference for further study on unicompartmental knee arthroplasty.METHODS: Web of Science, and PubMed databases were searched for the literatures published from January 1955 to April 2017 with the keywords of "unicompartmental knee arthroplasty, osteoarthritis, unilateral compartment, lateral knee arthroplasty".RESULTS AND CONCLUSION: A total of 562 articles were retrieved, and finally 75 English literatures were enrolled according to the inclusion and exclusion criteria. With the continuous improvement of unicompartmental knee arthroplasty, it can retain the cruciate ligament and more bone mass. Notably, strict indications and reasonable postoperative functional exercise are essential for obtaining optimal effectiveness. At the same time, the development of computer navigation and robot-assisted technology has opened up a new horizon for the treatment of osteoarthritis,which makes the operation more accurate and minimally invasive. But the application still needs to be studied in depth.
