Paul W. Ackermann, MD
Karolinska Institutet

Karolinska University Hospital
Stockholm, Sweden

Dr. Paul W. Ackermann is a Senior Lecturer at Karolinska Institutet, and orthopaedic surgeon at the Department of Orthopaedics and Trauma, Karolinska University Hospital, both in Stockholm, Sweden. His passion for sports and particularly basketball and soccer led him to get involved with sports injuries, and this was the reason to enter a residency in orthopaedics. His mentor, Professor Per AFH Renström, a well-respected figure in orthopaedic sports medicine, introduced him to the world of sports medicine.

The mission of Dr. Ackermann’s research is to understand and exploit neurovascular pathways in the musculoskeletal system for restoring joint function, alleviating pain, and minimizing complications.

Dr. Ackermann’s research has demonstrated that patients with Achilles tendon ruptures exhibit a high risk, 50%, of suffering deep venous thrombosis. Even a silent deep venous thrombosis has by Dr. Ackermann’s research group been demonstrated to affect the patients´ outcome at one year after the rupture. 

One means to facilitate the development of improved treatment of tendon injuries pursued by Dr. Ackermann’s research group is to develop biomarkers for early healing, which can predict long-term outcome. Currently Dr. Ackermann holds a grant from the Swedish Research Council to examine the effects of Intermittent Pneumatic Compression (IPC) on tissue repair and prevention of deep venous thrombosis during lower limb immobilization.

Robert C. Schenck Jr, MD
Chairman
, Department of Orthopaedics & Rehabilitation
Professor
University of New Mexico
Albuquerque, NM

Dr. Robert “Bob” Schenck Jr. is a Professor at The University of New Mexico (UNM), and Chair of the Department of Orthopaedics & Rehabilitation. In 1990, he began his career as a full-time academic physician at the University of Texas in San Antonio, where he taught and practiced Orthopaedic Sports Medicine for ten years. His love of the West, sports medicine, and orthopaedics matured when he moved to Albuquerque, New Mexico, to work at UNM. In 2006, he was selected as Chair of the Department of Orthopaedics & Rehabilitation, a position that he still holds today. Serving at both the School of Medicine and Athletic Department caring for Division I UNM Lobo athletes, Dr. Schenck has been asked to step into various leadership positions. In 2009, he led the building of an award-winning academic community hospital, adjacent to which recent construction began on the UNM Orthopaedic Center of Excellence. Bob was also asked to assist the University during the COVID-19 crisis supporting clinical leadership as interim Associate Deputy Vice Chancellor of Clinical Affairs. Although already serving as Chair and engaged clinician for shoulder and complex knee injuries, Dr. Schenck continues to serve in the additional leadership roles.

Bob was born in Texas and grew up in the Roaring Fork Valley in Carbondale, Colorado, later attending the University of Colorado at Boulder. Having great experiences with football and athletics, he knew he wanted to become a physician and hopefully, one day take care of athletes. His parents recall Bob announcing, at 17-years-old, that he was either going to become a United States Senator or an orthopaedic surgeon. In some ways, his leadership in orthopaedics was fashioned by his early interest in public service. After his sophomore year at the University of Colorado, Dr. Schenck moved to Baltimore, Maryland, to start the combined BA/MD program at John Hopkins University. He remained there throughout medical school and his orthopaedic residency.  Bob underwent sports medicine fellowship training with Dr. Frank Noyes in Cincinnati and later in foot and ankle training with Dr. Mike Coughlin in Boise.  His upbringing in the rural West, combined with his decade-long educational journey in the East, gave Dr. Schenck a wonderful foundation in life, broad exposure to the lifestyles of the USA, and an unforgettable medical training experience.

As a team physician at the UNM Athletic Department, Dr. Schenck is grateful for his membership in The American Orthopaedic Society for Sports Medicine (AOSSM). Dr. Schenck believes that the AOSSM has always represented excellence in care, research, and professionalism in the field of sports medicine. Bob considers his AOSSM membership as his most enjoyable, along with the experiences and friendships gained over the past 30 years. In 1991, he was selected as a traveling fellow, in which he toured the Western Pacific with his SLARD Godfather, Bernie Cahill. Dr. Schenck, along with his colleague and friend, Dr. Daniel C. Wascher, began giving back globally to host visitors’ tours from SLARD, ESSKA, and APKASS to AOSSM sites. Bob is grateful to Dr. Ned Amendola who selected Dr. Schenck as a Godfather to SLARD, and is most grateful for that experience traveling with fellows Dain Allred, Seth Sherman, and Marc Tompkins in South America in 2017. Dr. Wascher and Dr. Schenck are both grateful recipients of the benefit of a global sports-medicine educational and cultural sharing. With our global environment made closer with ZOOM, UNM has collaborated with many hosted fellows through publications and research. Dr. Schenck is grateful for all the patients he cared for, from high school and collegiate athletes at the University of Texas, San Antonio (1990-2000) and at UNM (2000-present). He is forever grateful to his sports colleagues and certified athletic trainers in caring for athletes.

Bob enjoys research, writing, and contributing to the academic sports-medicine community. One fascinating experience began with a publication in the American Journal of Knee Surgery in 1994, “A Baker’s Dozen of Knee Dislocations,” which triggered a long process of a paradigm shift in classifying knee dislocations. He has enjoyed managing the bicruciate knee and publishing extensively on the topic. In addition to receiving recognition as a JBJS Elite Reviewer twice, Dr. Schenck has enjoyed his participation on the AJSM Editorial Board since 2002. Approximately a decade ago, he began writing non-fiction and fiction and has won several awards. He now serves as editor for the UNM Arts Journal “The Medical Muse.” His published novella, “Juarez,” can be found on Kindle. He has a respect and understanding of the importance of scholarly activity and research at universities globally.

He met his spouse, Patricia (“Trish”) while in Baltimore, and they were married in 1986. Their experience together in an academic practice gave him a partner, a source of endless support, and a model for resiliency. Trish made the last fourteen years as chair an especially great honor for him. They recently celebrated their 34th year of marriage while maintaining a close relationship with their five children: Lillian, Gus, Helen, George, and Marian, ages 27 to 32. In his 14 years as the Chair of Orthopaedics & Rehabilitation at UNM, Dr. Schenck strongly believes in the importance of professionalism. His creed as Chair of the Department of Orthopaedics & Rehabilitation is “POISE”: Professionalism, Outcomes, and Integrity for Sustainable Excellence. Dr. Schenck has made a focused approach to maintain life balance and harmony of faculty, residents, and APP’s within his department. He is especially proud of creating a diverse faculty, and was recently nominated for the inaugural “He For She” Award offered by the Ruth Jackson Society and the American Academy of Orthopaedic Surgeons, with >25% women residents and faculty at UNM Orthopaedics. His work as chair has transitioned to include a focus on sharing opportunities with others to create a platform for future leaders. His focus of leadership is active-listening, collaboration, and fairness while recognizing that flexibility is tantamount for adaption so that he, his Department, and the profession may remain meaningful, successful, and prosperous in the global environment of Orthopaedic Surgery.

Miguel A. Khoury, MD
Sports Traumatology Specialist
Hudson, Argentina

I was born in the province of La Pampa, Argentina in a small town with 5.000 inhabitants named Realicó (a native name meaning “water plate”). My mother and one of my sisters still lives there.

My father was a rural physician who used to take care of every health problem in the town. He always mentioned to me that he would have liked to be an orthopaedic surgeon but residencies were not available at that time and he needed to get in practice quickly. He used to take care of fractures, delivering newborns and appendicectomies without an anesthesiologist assisting him. Ether anesthesia was used. The old Clinic founded by my father is still open with several young physicians running it.

My passion for sports and particularly tennis led me to get involved with sports injuries: that was my reason to enter a residency in orthopedics.

There was a prominent cardiovascular surgeon in Argentina named René Favaloro, who, after working as a rural physician close to my birthplace, moved to the U.S. to work at Cleveland Clinic, where he developed the heart surgery bypass. After a few coincidences and a basic science fellowship at Case Western Reserve University, Dr. Favaloro recommended me to enter the Cleveland Clinic fellowship program under Dr. John Bergfeld’s direction. After returning to Argentina, I got married to Andrea and we live now close to Buenos Aires City where I have my practice. We have two boys: Ezequiel, 19 years old (Engineering student) and Joaquín 17 years old (last year high-school student). Initially I was involved with a first division soccer team named Racing Club but, from all my medical activities, the most rewarding one is to take care of the Argentine Davis Cup Team. Consequently, I am able to be in an international tennis competition, not as a player, as I would have liked, but as a team physician.

Ring of Fire

Matthew Brick, MD
Sports Orthopaedic Surgeon
Millennium Institute of Sport and Health
Auckland, New Zealand

Matthew graduated first in class from the University of Auckland School of Medicine in 1986 and then made the unusual decision to never practice medicine.  A brief flirtation with business followed but this was not the answer either.  A chance entry into a local triathlon led to the discovery of a latent previously untapped large aerobic capacity.  An alternative career emerged with five years as a professional triathlete, duathlete and cyclist, culminating in two elite world championship titles in Duathlon in 1991 and 1992.  A recurring achilles injury forced a re-think.  The one certainty was staying involved with the sports he loved.  The most exciting way to achieve this was to return to medicine and train as an orthopaedic surgeon.

Matthew graduated from the New Zealand Orthopaedic Association training programme in 2002.  Fellowships followed with Dr. Freddie Fu in Pittsburgh, Dr. Mark Myerson (foot and ankle) in Baltimore and Dr. Keith Holt (Perth Orthopaedics and Sports Medicine, Australia).  It was while in Pittsburgh in 2003 that Matthew made contact with Dr. Marc Philippon at UPMC.  The emerging field of hip arthroscopy proved an exciting new area.  Freddie and Marc both proved great mentors encouraging clinical excellence and innovative research.

Matthew commenced private practice in 2005 based at the Millennium Institute in Auckland New Zealand under the practice name Orthosports North Harbour.  Arthroscopic surgery of the knee, shoulder and hip were his areas of practice through the first seven or eight years.  Gradually hip referrals from around New Zealand changed the case mix to being mostly hip arthroscopy with Matthew performing around 250-300 per year.

Hip arthroscopy patients have been followed prospectively from the beginning and clinical outcomes research has become Matthew’s main focus.  Although it is tempting to focus on our best results, it is the poor results where there is the most to learn and improve.  He was also involved in setting up the New Zealand National Rotator Cuff Registry. Matthew has enjoyed fellowship training a number of New Zealand and international surgeons.

Sport remains a passion.  He continues to test the limits of an ilio-tibial band autograft labral reconstruction performed in 2011 by his friend and early mentor Marc Philippon.  Events in the last two years have included three ultra-marathons and three half Ironman triathlons with age group wins in most.  Matthew and Tracey work together in the practice, with Tracey (also a doctor) focussing on post operative care and rehabilitation.  They have been married for 28 years and have four children: Claudia, Grover, Dexter and Wynton.  Those interested in food can visit www.thebrickkitchen.com to discover Claudia’s interest when she is not working as a junior doctor or logging operation day data for Matthew. (and yes, the boys were named after jazz musicians!)
