Dr. Ashley Mohan joins Rehabilitation Faculty

Ashley Mohan, DO, joined the Department of Orthopedics and Rehabilitation at the University of Wisconsin School of Medicine and Public Health as an Assistant Professor (CHS) on September 1, 2022. Dr. Mohan earned her Doctor of Osteopathic Medicine and completed a one-year fellowship in Osteopathic Manual Medicine at Des Moines University College of Osteopathic Medicine in Iowa. She went on to complete her internship year at Indiana University and her three-year residency in Physical Medicine and Rehabilitation at UW-Madison.

Dr. Mohan knew early on that she wanted to pursue rehabilitation medicine. Having grown up playing soccer and running on her high school varsity cross country and track teams, she experienced “almost every injury in the legs that you can imagine.” Not surprising, she did a significant amount of rehab under the care of an osteopathic physician. Over time, she grew fascinated by her treatment and found herself wanting to “learn the hands-on, manual therapy,” as she gained a better understanding of “how people can not only rehab injuries, but how they can prevent injuries from happening as well.”

A West Coast native from Lodi, CA (an hour south of Sacramento), Dr. Mohan “fell in love with Madison” when she and her husband moved here for her residency. She credits the supportive faculty at UW and the flexibility to pursue her specific areas of interest, including teaching, as major factors in her decision to stay in Madison.

Clinically, Dr. Mohan’s primary focus is neurological rehabilitation, including the treatment of strokes, spinal cord injuries, brain injuries, amputations, adult cerebral palsy patients, and multiple sclerosis. She also performs Botox injections for spasticity, nerve conduction studies and EMGs to test for peripheral nerve injuries, and she manages intrathecal baclofen pumps. In addition, Dr. Mohan consults at the main hospital for acute injuries and new amputations, helping to manage rehab diagnoses and ensure that patients have the appropriate follow-up and care as needed.

Dr. Mohan’s research focus is tied directly to the osteopathic manual therapy she provides in clinic. Because there is a significant lack of research in this area – and because she has seen how well OMT works for her patients – she has initiated a project that examines using osteopathic manual therapy in stroke patients.

Ultimately, Dr. Mohan’s strives to help her patients regain as much function as they can and adapt to a new way of life.

“Rehab medicine is unique for many reasons but what really motivates me to do this work is the ability to connect with patients on a deeper level and truly understand where they came from, how they are doing now, and where they hope to be.”

Welcome to the team, Dr. Mohan – we are so glad you are staying in Madison!

Two Orthopedic faculty members receive 2022 ICTR Pilot Awards

Uncovering the reason behind Type 1 Diabetes-related bone loss

Department of Orthopedics and Rehabilitation associate professor and researcher, Wan-ju Li, MS, PhD was recently awarded a $50,000 one-year Translational Basic & Clinical Pilot Grant from the UW Institute for Clinical and Translational Research (ICTR) for a proposal titled “GATA6 in Regulation of Type 1 Diabetes Mellitus-related Bone Loss.”  Dawn Davis, MD, PhD of the Department of Medicine is co-principal investigator for the project.

Why are Type 1 diabetes patients prone to bone loss?

Drs Li and Davis believe that the molecule GATA6 dysregulated in skeleton-forming stem cells in type 1 diabetes patients is a key player that connects the two diseases. Through their study, Li and Davis expect to “determine the role of GATA6 in regulating the pathological mechanism of type 1 diabetes-associated bone loss and provide insight into developing potential pharmacological treatments for the disease.”

A Minimally-Invasive Approach to Correcting Leg Length Discrepancy in Children

Yet another dynamic collaboration receiving a one-year, $50,000 ICTR Pilot Grant was UW Orthopedics and Rehabilitation faculty member, Kenneth Noonan, MD and his co-PI, Christopher Brace, PhD of the UW Radiology and Biomedical Engineering departments. Funding from this grant will support their project, “Microwave Ablation to Correct Leg Length Discrepancy in Children.”

Drs. Noonan and Brace aim to develop a safe, less invasive treatment for children with limb length discrepancy (LLD) greater than three centimeters by adapting an alternative to the condition’s standard treatment – a surgical procedure that mechanically disrupts growth plates using drills. Microwave ablation, a “well-tolerated method to destroy tissue through highly localized heating,” is a tried and true technique that “has been used widely in other contexts such as liver cancer treatment.”

Their goal is to determine the effectiveness of using targeted microwave heating to ablate the growth plate (curtailing bone growth) in growing pigs, paving the way toward using this method in human subjects.


The ICTR Pilot Awards Program funds projects that focus on cross-disciplinary research, emphasizing “innovative research methods, team science, health equity, and impact.”

Partial knee replacement gets Dave up and running again

Dave Kunstman is a busy guy. A Family Medicine doctor who also serves as the interim Chief Medical Officer for UW Health, Dave cherishes physical activity as a way to stay healthy while clearing his mind.

“A 15- or 20-minute run makes my day,” Kunstman says. “It allows me to shut everything else out for a brief time, which is really helpful. It is a mindfulness practice for me.”

In early 2021, Dave, then 53, began experiencing pain in his left knee during his ritual runs. Before he knew it, he had to stop running and get it checked out. An imaging procedure revealed bone-on-bone osteoarthritis in the medial portion, or inside half, of the knee. Physical therapy didn’t help. He even tried acupuncture, which didn’t do much either.

Eventually, the UW Health Sports Medicine team referred Dave to Dr. Brian Nickel, a UW Health orthopedic surgeon who recommended a partial knee replacement.

“The beauty of a partial knee replacement is that we only replace the damaged portion of the knee, rather than the entire knee,” Nickel says. “If only one of the three sections of the knee is damaged, a patient might be a candidate for a partial, however many people do not qualify because too much of their knee has deteriorated. As a young patient with all knee ligaments intact and damage confined to one area, Dave was a good candidate for a partial replacement.”

Faster recovery

Not only do patients recover faster from partial (versus total) knee replacements, Nickel says, but satisfaction is often greater because existing healthy tissue and bone are preserved. This usually results in greater range of motion and knee function. The only downside, he says, is that partial knee replacements fail at a slightly higher rate than total knee replacements — about 3 percent per year versus 1 percent per year.

Like several of his primary care colleagues, Dave wasn’t all that familiar with partial knee replacements.

“A partial knee replacement is actually more technically challenging than a total knee,” says Nickel, who performs about 400 knee replacements a year, about 10 percent of which are partial replacements.

Confident in Nickel’s experience and track record of excellent outcomes, Dave decided to move forward. A surgery date was set for late June 2022.

“I arrived at 6 a.m. and was on my way home by noon,” Dave says. “I was up and around with crutches that same day. After 3 days, I was walking without crutches. Within 3 weeks, I started biking, hiking, and swimming. There was some temporary surgical pain that everyone has, but the pain from the knee arthritis was entirely gone.”

Two months following surgery, Dave began preparing to resume his beloved running routine, guided by a back-to-running program from UW Health Sports Medicine therapists.

Long wait for total knee replacement averted

“The difference is pretty remarkable,” he says. “I know I may need to have a total knee replacement down the road, but it might not be for at least another 12 to 15 years. Having the partial knee replacement right away saved me from spending at least another 10 years missing out on running while waiting for my knee to get bad enough to need the full replacement.”

By telling his story, Dave also hopes more primary care doctors will appreciate what a valuable option partial knee replacements can be for their own patients.

“When I came back to work and people asked me about it, quite a few were not aware that partial knee replacements were a thing,” Dave says. “Hopefully, my experience will result in many other patients exploring this as an option for themselves. I have nothing but great things to say about my experience.”

Joseph Mitchell, MD, joins the UW Department of Orthopedics and Rehabilitation

Joseph Mitchell, MD, joined the Department of Orthopedics and Rehabilitation at the University of Wisconsin School of Medicine and Public Health on May 1, 2022. Originally from Milwaukee, Wisconsin, Dr. Mitchell earned his BS in Biology from the University of Wisconsin-Parkside. He then completed medical school and residency at the University of Wisconsin School of Medicine and Public Health. Following his residency, Dr. Mitchell went on to fellowship for one year at the University of California-San Diego, where he broadened and further honed his joint replacement skills.

After completing his fellowship, Dr. Mitchell practiced with Aurora Orthopedics in Sheboygan, WI. However, not long after he had begun to practice outside of academics, Dr. Mitchell discovered that he missed the curiosity and engagement of the medical students, residents, and fellows he had worked with throughout residency and fellowship.

Thus, when he learned of an opening for a joint replacement specialist in our department, he was thrilled at this opportunity to return to what he feels is his “medical home.”

An orthopedic surgeon specializing in adult reconstruction of the hip and knee, Dr. Mitchell is highly skilled in both primary and revision hip and knee replacement surgery. He has specific expertise using the anterior approach for hip replacement – a technique known to have a steep learning curve. Dr. Mitchell has performed over 800 joint replacements, using the anterior approach in many of these cases. In fact, because of his extensive training and experience – and because this approach expedites patient recovery by as much as three months, according to some studies – Dr. Mitchell uses this technique almost exclusively when performing a hip replacement.

Also certified to do robotic knee and hip replacement, Dr. Mitchell is trained in patient-specific instrumentation, or patient-specific implants, using their own anatomy to create the ultimate implants that are used.

Reflective of his goals and passions, Dr. Mitchell’s research interests include comparing the advantages of anterior approach hip replacement vs. the traditional posterior approach. He is also investigating the use of robotic navigation vs. traditional instruments (manual instrumentation) to determine if computer navigation makes a difference in patient outcomes. In addition, he plans to both study and work toward increasing diversity within the orthopedic field.

The factor that initially drew Dr. Mitchell to the orthopedics specialty – and why he is so passionate about both practicing and teaching in the field today – is that “more than any other specialty, orthopedics enables a physician to quickly improve a person’s quality of life with a short procedure.”

“What really drives me is knowing that, although the surgical procedure itself is the same every time, for that individual, you are putting them back to a place they were 10, 15, maybe 20 years ago, in terms of their mobility and their quality of life. You give them back their ability to get out and just enjoy the things they enjoy doing. Seeing those patients at follow up and having them do very well, that is what motivates me to keep doing what I’m doing.”
