Meet Kelly C. McInnis, DO: Women's Sports Medicine Doctor

After playing Division 1 soccer at Boston College, Kelly McInnis, DO, turned her passion for sports into a career as a sports medicine physician and physiatrist at Mass General Brigham Sports Medicine, where she is the director of Nonoperative Sports Medicine and a lead physician in the Women’s Sports Medicine Program.

Dr. McInnis is a team physician for the Boston Red Sox, the New England Patriots, and Harvard University. She’s also a team consultant for the Boston Ballet, Boston Bruins, and New England Revolution.

Dr. McInnis was also Venue Medical Officer in Boston for the FIFA World Cup 2026 played at Gillette Stadium.

In this Q&A, she discusses her work caring for athletes at all levels, the future of the Women’s Sports Medicine Program, and collaborating with her colleagues in orthopedic surgery.

Q: What are some of your priorities helping to lead the Women’s Sports Medicine Program?

McInnis: Our primary goal is to advance the care of the female athlete.

There is much less attention and research focused on female athletes compared to their male counterparts, whether it’s female-specific sports, like softball, or sports played by both sexes, like soccer. Women’s sports have been expanding, not just in the number of female athletes but in the variety of the sports they play at amateur and elite levels and everything in between.

We know there are clear differences in anatomy and physiology between men and women. Women experience hormonal changes during adolescence, pregnancy (during and post-pregnancy), and menopause. We need more research to understand how these changes impact physical condition and performance. Female athletes also have physical differences that put them at greater risk for certain hip injuries, knee injuries like ACL tears, and bone stress injuries.

We have much to learn about sex differences in several other arenas of sports and exercise medicine, including mental health, sports nutrition, sports cardiology, performance enhancement, and injury prevention. With a deeper understanding of how these differences contribute to injury and illness, we can begin to provide better care for female athletes at all levels.

We’ve developed specialized strength and conditioning programs so women can get stronger in the muscles that are usually weak. The goal is to prevent long-term recurrent injury and keep them in the game longer.

Q: What are your goals for the partnership between Mass General Brigham Women’s Sports Medicine and Boston Legacy FC? How do you see your role as chief medical officer for the club influencing care?

We are so thrilled to be the medical provider and sports medicine partner for the Boston Legacy FC in its inaugural season.

Our goal with the partnership is to deliver exceptional care to the Boston Legacy athletes, with the highest level of expertise and commitment. We’ve assembled a team that has dedicated their careers to advancing women’s sports medicine through research and patient care.

The multidisciplinary team understands that professional female athletes have specific medical and musculoskeletal needs that must be considered and addressed to prevent injury and illness, and of course optimize performance, health, and wellness of these players on and off the pitch.

My role as chief medical officer for the club is to ensure these elite athletes get the elite care Mass General Brigham Sports Medicine has provided to other New England professional sports teams, tailored to the unique needs of female athletes. From pre-season physicals through the last goal of the season and beyond, we’re caring for the whole person health of these athletes.

Q: Can you describe your work as a team physician for the Boston Red Sox and the New England Patriots?

McInnis: Professional athletes have unique needs. The demand of their sport is elite-level. It is their job and livelihood. Because of this, injuries are high-stake. We individualize needs based on sport, position, stage of career, personal goals, etc. We have a comprehensive approach to evaluation, management, and secondary prevention. This is similar to what we do for the amateur athletes, where patients are just as passionate but stakes are not quite as high.

Q: What is your role on game day?

McInnis: I am part of a team of specialists that provides game day medical coverage for the Boston Red Sox during spring training and the regular season We address medical issues and injuries that occur acutely on the field of play. Our priority is always the health, safety, and well-being of our athletes. We advocate for our athletes, always with their best interests and safety in mind, regardless of the landscape of the importance of the game or season.

Q: How does your experience caring for professional athletes benefit your other patients?

McInnis: When treating professional athletes, we utilize all the experts on our team to deliver the best possible care. We consider state-of-the-art, evidence-based treatment tools, as well as cutting-edge interventions, to provide safe and expeditious return to play. This is the very same approach we take for our amateur athletes.

I really enjoy taking care of recreational athletes and even just passionate exercisers. We know that exercise is medicine in many ways. Treating athletes of all levels and active individuals of all levels is what I really enjoy.

Q: How do you approach patient care as a physiatrist?

McInnis: We’re trained to treat all musculoskeletal injuries and impairments, as well as neurologic injuries and impairments. For my orthopedic counterparts, their primary goal is to restore anatomy. So they're trying to surgically reconstruct or restore anatomy that's been injured, as opposed to the physiatrist, where the primary role is to restore function.

We're looking at the whole person, the whole picture. If I'm examining a patient with knee pain, I'm looking at the hip, the spine, the foot and ankle. All these body structures play a role in how the knee performs.

Q: How do you and your colleagues in orthopedic surgery work together to care for patients?

McInnis: We work well together and provide complementary care, whether we're seeing a patient after surgery or before surgery. Ninety percent of sports medicine care is nonoperative, so we discuss all nonoperative management options and exhaust this treatment if appropriate. And we expedite care to the appropriate surgical specialist if surgery is warranted or nonoperative treatment fails. Surgeons rely on us for our nonoperative expertise and often send us patients for interventions such as injection therapy.

An athlete may see me and they may not know if it's a surgical issue or not. And through the evaluation process and attempting some nonoperative treatment measures, they may ultimately end up needing surgery. By the time I send the patient to a surgical colleague, their expectations are set. This helps my surgical partners in terms of efficiency and developing a relationship with the patient.

Sometimes I'll see that patient after surgery as well, alongside the physical therapist. I counsel them on getting back to their desired activities and sports.

Q: How do you envision the future of Women’s Sports Medicine?

McInnis: The field is relatively new, with a bright future. We plan to lead the advancement of Women’s Sports Medicine in clinical care, research, education, and community engagement. Women continue to make significant strides in participation and performance in athletics. We aim to advance our care in parallel, and ultimately provide the highest level of comprehensive, multidisciplinary care.

Q: What is your favorite part about working with the Mass General Brigham Sports Medicine team?

McInnis: I am incredibly fortunate to be part of an exceptional group of providers at Mass General Brigham Sports Medicine. It is our athlete-centered care and our teamwork that makes this a special place to work.
