Andrew Foggitt is a UK-trained Consultant Orthopedic Surgeon who studied at Liverpool University Medical School, before undertaking his surgical and orthopedic training in the Wessex region of the South of England. He passed the orthopedic exit exam in 2000 and took up a Consultant post in November 2002 in Winchester, UK, as a General Orthopedic Surgeon with a specialist interest in foot and ankle surgery. This was a new post, and he set up a foot and ankle service, which was sufficiently successful, that he had to give up his general orthopedic practice to concentrate on purely foot and ankle surgery, which he continued, for over 19 years before moving to the Burjeel Hospital in Dubai, full-time, to provide foot and ankle services to the local population. He is supported by an integrated hospital team, providing a holistic service, including nurses, physiotherapists, podiatrists, orthotics, and a dedicated back-room team who will assist you through your hospital journey. He looks forward to providing you with personalized service to look after your foot and ankle problems. His areas of expertise include, 

• Arthritic conditions of the foot and ankle
• Sports injuries of the ankle
• Ankle arthroscopy
• Tendon transfers
• Reconstructive surgery
• Achilles tendon disorders
• Plantar fasciitis
• Curly toes, bunions, and ingrowing toenails

Prof. Enrico Arnaldi is the Arthroscopic and Reconstructive Surgery of the Knee Unit Director in Humanitas Research Hospital. 
He was the medical apprentice of Dr. Lorenzo Spotorno (a master and pioneer in prosthetic surgery). Since 1984, he has dedicated himself to arthroscopic knee surgery and later on shoulder surgery.

Medical areas of interest: He is specialized in degenerative and post-traumatic shoulder diseases (rotator cuff tendon injuries, glenomeral arthrosis, shoulder instability) and related surgical treatments, arthroscopic (tendon repairs, capsuloplasty, etc.) and open (latarjet stabilization, orthoprosthesis, etc.). 
He also deals with degenerative and post traumatic knee pathologies, with particular attention to the osteoarthritis of the knee (primitive or secondary), the post-traumatic complex capsule-ligamentous instabilities, the lesions of the cruciate ligaments, meniscus and cartilage, and open-air surgical treatments (such as corrective osteotomies, first implant orthoprosthesis and revisions) and arthroscopic (meniscectomies and meniscal sutures, meniscal transplants, ACL reconstruction, treatment of focal cartilage lesions). 

Research areas of interest:
There are many research interests, ranging from biotechnology to meniscal transplants and osteochondral grafts, from allogeneic grafts for reviews from failures of ligamentous reconstruction to patella stabilization.

He practiced his specialty in the US in some of the world-renowned medical institutions along with internationally famous doctors: the University of Pittsburgh (Dr. Freddie Fu, Dr. Harner, Dr. Savio Lee Wo), the Intermountain Hospital in Salt Lake City (Dr. Rosemberg, Dr. Paulos), Dr. E. Wolf (San Francisco), Dr. Helman and Dr. Morrison (Los Angeles), Dr. Nottage, Dr. Esch (San Diego), Dr. Steadman and Dr. Hawkins (Vail), Dr. P. Fowler (London Ontario Canada), and J. P. Warner in Boston University.

He has performed more than 10,000 arthroscopic knee surgeries and approximately 1,200 prosthetic reconstruction of the knee. He has always been very involved in the research works in the area of new biotechnologies, meniscal and osteochondral transplantation, allogeneic grafts for revisions by failures of ligament reconstructions, stabilization of the patella.

About me

I graduated from Izmir Dokuz Eylul University with the orthopedics branch. After I graduated, I carried out some

studies focusing on especially on

joint and cartilage surgery and stem cells. In this, I worked with many professional and amateur sport clubs. Also,

I worked on joint replacement surgery

for further aged people. Approximately, I achieved 10 thousand people who took knee and hip replacement

surgery from me. I attended to many international conferences about joint and cartilage surgery. Now I start

Ortocare Clinic for orthopedics and health center. In here, I treat my patients using the most advanced

technologies in the world, such as foot health centers, electromagnetic therapy, cryocabin therapy, backup

therapy and stem cell therapy. In our clinic, I continue to my work on non-surgical treatments, especially antiaging

treatment, and to eliminate pain problems in patients. On top of that, I also carry out some post-operative

rehabilitation and medical plates exercises.

During his career, Dr. Covaro has a continuous participation in international meetings and contributed to several articles published in scientific magazines. Dr. Covaro is a member of several professional organizations, including the Spanish Society of Orthopedics, AOspine, GEER and Eurospine.

Currently, Dr. Covaro attends his patients at the Institut Universitari Dexeus and the Hospital Universitari de Bellvitge, in Barcelona. To make an appointment with Dr. Augusto Covaro, contact ICATME, Institut Universitari Dexeus
