After completion of his orthopedic residency at the ASEPEYO Orthopedic and Rehabilitation Hospital in Madrid (Spain), he was graded as Doctor in Medicine by the Universidad of Alcalá de Henares (“cum laude” grade). Doctoral Thesis: “Femoral and tibial tunnel study in ACL reconstruction. CT scan and clinical long-term results”.

His clinical interests are sports medicine and arthroscopy of the knee and shoulder. Special interests include ACL reconstruction, knee cartilage restoration, meniscal injuries, shoulder instability in athletes and biological treatment for sports injuries. His research interests are mainly focused on ACL reconstruction and several techniques for post-meniscectomy syndrome.

Dr. Ayala is accomplished in both clinical and laboratory research and has authored more than 40 scientific manuscripts and textbook chapters. He has received 10 national and international recognition and awards on lectures and publications within the field of sports medicine. Reviewer of Revista Avances, Revista Española de Cirugia Ortopedica y Traumatología, AJSM (American Journal of Sports Medicine) and The Knee.

He is an active member of AEA (Asociación Española de Artroscopia), EMTG (European Meniscal Transplantation Group), SECOT (Spanish Orthopedic Surgery Association), SETRADE (Spanish Society for Sports Traumatology), SLARD (Latin-American Society of arthroscopy, knee and sports traumatology) and ESSKA (European Society of Sports Traumatology, Knee and Arthroscopy).

Dr. Ayala is an avid paddle tennis player, skier, and piano student but enjoys most spending his days with his fiancé Cristina and his children Maria and Jaime.
