3. Letter of motivation/career goals.
Since the start of my Ph.D. program, I have had an interest in OA mechanism with cartilage homeostasis. My Ph.D research was glycosaminoglycan (GAG) concentration with knee alignment, and clarified no indication of high tibial osteotomy for severe varus knee based on the GAG concentration (JOR 2008). Subsequently, I went abroad to determine the mechanism of OA at The Scripps Research Institute for 3 years. Professor Martin Lotz supported my researches on GAG loss and chondrocyte biology (A&R 2008), and the effect of heparan sulfate endosulfatase (Sulf) for OA (AR&T 2008, PNAS 2010).
Since 2011, I have been working on biological knee reconstruction and have continued cartilage related research in my roles as an assistant professor in Osaka Medical College. My short-term goal is to establish translational research from bench to bedside, particularly as it applies to biological reconstruction of the knee.
As related to the clinical side, I am very interested in patellofemoral (PF) instability. I recently reported on a new surgical procedure for patellar instability with patella alta in this year (JOS 2013). Of particular interest to me is the study of cartilage degeneration in the PF joint. It is my desire to learn good surgical techniques and gain a biological understanding particularly of the cartilage degeneration with PF joint.
In basic part, researches with the graduate students about meniscus remodeling and the effect of intra-articular Sulf injection for OA knee were accepted at next ICRS congress in Izmir. My previous research continues through collaborations with Prof. Martin Lotz and investigating the possibility of Sulf for chondrocyte protective effect.
My long-term goal in combining my clinical and basic research experience would be identify a novel and evolutionary cartilage tool, which will benefit patients and society.
