June Highlight | Education

Educating the future generations of health care providers has been a part of TRIA history since the very beginning. We have more than 200 graduate medical education experiences annually at TRIA. TRIA is a primary rotation site for the University of MN Department of Orthopedics residents. Residents currently spend time at TRIA in their second, fourth, and fifth years rotating through sports, foot/ankle, and hand. The experience TRIA has to offer the residents is phenomenal. The educational value of seeing a high volume of bread and butter orthopedic injuries positions this next generation of orthopedic surgeons well as they either go on to a fellowship or enter practice after graduation. One unique opportunity that our residents have at TRIA is access to the Surgical Skills Lab. In their first year, residents complete their gross anatomy course at TRIA. Then in their second, third, and forth years they have an opportunity to do knee and shoulder arthroscopy – learning more complex procedures as their progress through their residency.

Thinking of the conferences you have attended, and talks you have given, what would you say was your most interesting experience?
For sure it would have to be other countries where I have had the opportunity to teach and work. I have been very fortunate to do that in quite a few places, all of which have been special in some way, but I would have to say that my visits in Cuba have been particularly noteworthy. The physicians there are incredibly well trained, and in many cases have developed some of the same approaches and ideas to providing care as elsewhere. They have done so, however, in something of a bubble and with fewer resources than most of the rest of the countries with more advanced medicine; there is a lot to learn from that.

Would you share a favorite quote or best advice you have received?
I just got to visit the Martin Luther King Jr. National Historic Park in Atlanta. Dr. King obviously had many significant quotes, but one that I saw more than once and resonated strongly with me was "Life's most persistent and urgent question is 'What are you doing for others?”

If you could be cast in a movie of your choice, what movie would you choose and which character would you want to play?
I think I would probably enjoy being in a superhero movie, not because I fit the role, but just because I am entertained by the movies. Since I speak Norwegian, I guess I would have to be Thor, plus I have the appropriate physique.

Juvenile osteochondritis dissecans (JOCD) is a developmental disease characterized by formation of intra‐articular (osteo)chondral flaps or fragments. Evidence‐based treatment guidelines for JOCD are currently lacking. An animal model would facilitate study of JOCD and evaluation of diagnostic and treatment approaches. The purpose of this study was to assess the suitability of miniature pigs as a model of JOCD at the distal femur. First, stifle (knee) joints harvested from three juvenile miniature pigs underwent MRI to establish the vascular architecture of the distal femoral epiphyseal cartilage. Second, vessels supplying the axial or abaxial aspects of the medial femoral condyle were surgically interrupted in four additional juvenile miniature pigs, and the developing epiphyseal cartilage lesions were monitored using three consecutive MRI examinations over nine weeks. The miniature pigs were then euthanized, and their distal femora were harvested for histological evaluation. Vascular architecture of the distal femoral epiphyseal cartilage in the miniature pigs was found to be nearly identical to that of juvenile human subjects, characterized by separate vascular beds supplying the axial and abaxial aspects of the condyles. Surgical interruption of the vascular supply to the abaxial aspect of the medial femoral condyle resulted in ischemic cartilage necrosis (a precursor lesion of JOCD) in 75% (3/4) of the miniature pigs. Cartilage lesions were identified during the first MRI performed 3 weeks post‐operatively. No clinically‐apparent JOCD‐like lesions developed. In conclusion, miniature pigs are suitable for modelling JOCD precursor lesions. Further investigation of the model is warranted to assess induction of clinically‐apparent JOCD lesions.
