We pride ourselves in an ‘outside-the-box’ approach to understanding the mechano-biological response of the knee joint and to developing innovative approaches to the clinically relevant problem of knee joint degeneration after injury. Our models span the spectrum from cells, to tissues, to joints and as such allow for a comprehensive study of the effect of injury and repair on joint tissue response.
The goal of Dr. Maher’s laboratory is to understand the relationship between knee joint contact mechanics and the biological response of articular cartilage and meniscus. This information is used to direct the development of implants, scaffolds, or modified surgical techniques to intervene in the degenerative process that occurs after injury. Her laboratory is currently developing biomaterials for joint restoration that can be used to treat young active patients with chondral or meniscal defects early in the course of the problem, thus delaying the need for a total joint replacement.
The Maher team has built multi-scale, multi-system models to help them understand how knee-specific factors affect joint contact mechanics and how injury affects the mechanics of the knee joint. They are using the models to assess the ability of scaffolds/ implants to restore pre-injury mechanics to the knee joint and to assess the ability of implants to integrate with the host tissue. One such implant for the treatment of cartilage defects is currently at an advanced level of pre-clinical testing, supported in part by the BioAccelerate NYC Program.
Our laboratory consists of mechanical engineers, biologists, chemical engineers and orthopaedic surgeons from the Sports Medicine Service. We have multidisciplinary collaborations with statisticians, and computational engineers which enable us to combine state-of-the-art cadaveric, computational, statistical, tissue explant and patient-based models.

Claire Lynch, B.Sc
Roanne Yehia, BS
Claire Lynch joined the Soft Tissue Research laboratory at HSS in March 2019 as a research technician. She graduated from University College Dublin, Ireland in September 2018 with a B.Sc in Neuroscience.
She is currently focusing on understanding the cellular response of joint contact mechanics; in respect to osteoarthritis. Her work involves applying various mechanical loads (pre- and post-injury) to human cartilage; with the goal to further our understanding of the cellular and molecular mechanisms in response to these loads. She is also working on identifying the variability in histology and shear mechanics between donor osteochondral allografts.
Roanne Yehia is a graduate of Cornell University College of Engineering. Her research focuses on “developing systems and technology to understand contact mechanics as it relates to physiological function and patient outcomes” in the laboratory of Dr. Suzanne Maher.

Dr. Mehdi Khoshgoftar is currently an Adjunct Assistant Scientist at HSS. Dr. Khoshgoftar has interests in multiscale mechanics of (bio)materials and (bio)structures. In particular, he is interested in computational biomechanics of the knee joint and soft orthopaedic tissues such as articular cartilage and meniscus. Dr. Khoshgoftar obtained his doctoral degree in Biomedical Engineering from Eindhoven University of Technology, Netherlands, in 2012 with Prof. Keita Ito and Dr. Rene van Donkelaar. His doctoral research focused on computer-aided tissue engineering of articular cartilage. Prior to joining Prof. Suzanne Maher’s lab at HSS, Dr. Khoshgoftar completed a Postdoctoral Fellowship at Radboud University (Nijmegen, Netherlands) with Prof. Nico Verdonschot. His research focused on the design and mechanical evaluation of anatomically shaped polycarbonate urethane total meniscus implant. Dr. Khoshgoftar has also worked as a patent engineer in a European patent organization, Deltapatents, in the Netherlands.
