His practice is exclusively confined to problems in and around the hip joint, with special expertise in surgical treatment of young adult hip disorders. 

Whilst a painful hip is challenging at any age, younger patients can find it particularly difficult due the demands of education, employment and family life. They may also face disbelief or even hostility about their condition due to the false but widely held public (and often medical) opinion that hip surgery consists only of hip replacements and broken hips in the elderly. 

There have been huge advances in the understanding and treatment of hip pain in the last decade and in that time a whole new branch of surgery has developed, known as hip preservation surgery, so-called because the patient’s own hip joint is preserved rather than replaced. 

Marcus is recognised as an opinion leader in young adult hip problems having established hip preserving operations such as Minimally Invasive PAO for hip dysplasia, hip arthroscopy for FAI, and total hip replacement for sickle cell disease in the UK. Marcus brings this knowledge and experience to manage patients facing the difficult decision to proceed with hip replacement surgery when the hip is too painful and damaged for other treatment to be effective. 

Marcus has lead the use of very hard wearing ceramic on ceramic total hip replacements that allow patients of all ages to enjoy decades of excellent hip function from their replacement without fear of it wearing out.

Marcus is a member of the British Hip Society (BHS), the International Society of Hip Arthroscopy (ISHA) and the British Orthopaedic Association (BOA). He regularly shares his experience at Society meetings as well as The London Hip Meeting and Sickle Cell in Focus. He is a reviewer for The Bone & Joint Journal, Hip International and The Journal of Hip Preservation Surgery. He is a member (and former Chair) of the Steering Group for the BHS Non-Arthroplasty Hip Registry, the only registry in the world which documents procedures and patient outcomes for hip preservation surgery and hip arthroscopy.

His interests outside work include film, TV and contemporary music, Apple electronic goods, North American Sport and cycling.
