Dr. Marcus is a practicing orthopaedic surgeon in Northern Virginia with extensive experience in sports medicine, joint reconstruction, and cartilage restoration. Dr. Marcus has performed numerous cell based cartilage transplants using the autologous chondrocyte implantation (ACI) technique since 1997. He has published over twenty articles in the orthopaedic literature and has worked with teams at both the University of Virginia and George Mason University on the development of genomic and proteomic science as applicable to cartilage. He has been working with Dr. Jennifer Elisseeff, Associate Professor of Biomedical Engineering at Johns Hopkins University, since 2001 on the use of biomaterials to correct cartilage lesions. Dr. Marcus is a Founder and Chief Medical Officer of Cartilix, Inc. and the former Chief Science Officer of Cell Mechanics, LLC. He is a member of the Orthopaedic Research Society, the International Cartilage Repair Society, and the International Society for Stem Cell Research. Dr. Marcus is a graduate of the Johns Hopkins University (BA), Stanford University School of Medicine (MD), and the Orthopaedic Residency Program of the University of New Mexico.
Dr. Marcus has dedicated his practice to the restoration of damaged cartilage. Not all patients can be helped by present methods, and first and foremost it is necessary to identify appropriate patients for reconstruction, and to make sure that their expectations are in line with present technology. Evaluation is often aided by state-of-the-art MRI techniques using special cartilage specific sequences. Many MRI scans are not up to the task of providing valid cartilage information. Outpatient, minimal incision arthroscopy, sometimes using the Innervue Scope, can in some patients require only local anaesthesia. Newer techniques, such as infrared imaging, are being evaluated in the lab for this purpose.
The continuum of cartilage repair now includes debridement, microfracture, autologous transplantation, and osteochondral allografting. In the works are some novel medical devices, and interesting new cell based therapies. The goal in each case is to restore function, improve activity levels, reduce or eliminate pain, and to stave off the advanced degeneration of the joint that now requires rebuilding with metal and plastic (“total joint”) components.
