Background Information 
Professional profile:

Mr Iain Lennox is a consultant orthopaedic surgeon at Spire Hartswood hospital in Brentwood, Essex, offering specialist private hip and knee surgery, foot and ankle surgery and general orthopaedic surgery in our clean and comfortable private hospital. He is a fully private orthopaedic surgeon.

Mr Lennox's main interests are in the treatment of early arthritis of the knee and ankle; sports related injuries of the knee and ankle; arthroscopic (keyhole surgery) operations on the knee and ankle and personalised knee replacement surgery. In addition to total hip replacement surgery he also offers hip arthroscopy. He also has a particular interest in foot surgery and carries out ankle replacement surgery. He places enormous importance on rehabilitation following surgery and, to this end, runs his own rehabilitation clinic.

Medical training and surgical experience

Iain Lennox qualified in medicine from the Royal London Hospital, Whitechapel in 1983. He was made a fellow at the Royal College of Surgeons in Edinburgh in 1988 and awarded a knee fellowship at the Royal National Orthopaedic Hospital, Stanmore in 1989.

In 1995 Mr Lennox was made a fellow of the Royal College of Surgeons in the specialty of orthopaedic surgery. He was awarded a postgraduate diploma in biomechanics at the University of Strathclyde and a fellowship in knee surgery (specialising is sports surgery) at Duke University, North Carolina, USA. 

Iain Lennox was formerly a Consultant Orthopaedic Surgeon at Basildon and Thurrock NHS Trust and received a higher degree of Doctor of Medicine from Aberdeen University in 1996. He was appointed to The Court of Examiners of the Royal College of Surgeons of Edinburgh in 2000.

Personalised knee replacement using the Signature knee

Early in 2012 Mr Lennox introduced personalised knee replacement surgery for his patients at Spire Hartswood Hospital. In October 2012 he achieved another 'first' when one of his patients went home from Spire Hartswood less than 24 hours after her personalised knee replacement operation.

Hip arthroscopy (keyhole surgery of the hip)

Iain Lennox regularly performs hip athroscopy at Spire Hartswood Hospital. This 'keyhole surgery' technique has advanced in recent years but is still not widely available, even in private hospitals. Hip arthroscopy allows the orthopaedic surgeon to visualise the inside of the hip joint and to repair cartilage damage. The cartilage rim of the hip joint socket may be torn and need trimming or repairing. Loose bodies can be removed and any irregularity in the shape of the femoral neck region can be smoothed off to reduce pain and improve mobility. Treatment by hip arthroscopy may reduce the chances of subsequently developing osteoarthritis and needing a hip replacement.
