Mexico City, Mexico
Dr. Miguel is a Professor at University UNAM (Universidad Nacional Autonoma De Mexico) sports medicine fellowship training program at Angeles metropolitano hospital. In 1981, he began his career as a full-time academic physician at the University UNAM, where he is a sports medicine program co-founder and has taught and practiced orthopedic sports medicine for 17 years. He also was part of the trauma service staff as an orthopedic surgeon at Lomas Verdes hospital from 1981 to 1986. Finally, he is also an ATLS professor and program director in Mexico since 1989. He has been a part of the professional Mexican soccer team “Pumas”, for the last 25 years.

He is very committed with the academic activities of the society, and he always use the journal as a reference for his fellows and his daily practice. Since 2007 he is an active member of the editorial board. Dr. Miguel is a very committed professor, and is the chairman of the sports medicine and sports trauma fellow ship at UNAM and Angeles metropolitan hospital. He still works at his private practice mostly knee and shoulder pathology, and also sports trauma related issues.
Pieter (Spike) Erasmus
Knee Surgeon in solo private practice
Stellenbosch, South Africa
Pieter, better known as Spike, which is his nickname, grew up on remote stock farm in South Africa.
He graduated from the University of Stellenbosch obtaining an MMed (Ortho) cum laude in 1979.
With an early interest in knee surgery he attended one of the first instructional courses on arthroscopic surgery organized by Dr Sprague in Hawaii. After the course he spend some time at the Hospital of Special Surgery in New York with Dr Insall.
During his studies he played rugby and participated in cross country running, representing the university in running. He is still running and able to do 10km in under 50 minutes. Spike loves the outdoors; breeding and training Vizsla dogs, doing cross country motorbike trips and hike.
His practice consists solely of knee surgery, from simple arthroscopic procedures to complex TKR revision surgery. Having a special interest in the biomechanics of the knee, he has an affiliation with the engineering department of the local university.
