Dr Krishnan qualified from Maulana Azad Medical College in 1976 and went on to complete MS from Central Institute of Orthopaedics at Safdarjang Hospital in 1980. After Senior Residency, he obtained further training and qualifications in the UK, including MCH from Liverpool with Norman Roberts medal, PHD from Royal Postgraduate Medical School and Hammersmith Hospital in London and the UK Intercollegiate Specialty Board Examination of the Surgical Royal Colleges.
He joined Indraprastha Apollo Hospital in 1995 as Senior Consultant in Orthopaedics and set up a tertiary spine service. He was appointed in 1999 as full time Consultant Orthopaedic Spinal Surgeon at Mid-Cheshire NHS Trust with private practice at BMI South Cheshire Hospital and Spire Stretton Hospital. He set up a spine service from scratch in East and South Cheshire and his practice focused exclusively on spinal surgery. He trained specialist registrars from the Mersey Rotation, in spine surgery.
His practice for over 20 years has been exclusively spine surgery both in the UK and since his return to Apollo in April 2012. He treats spinal disorders ranging the gamut from disc and degenerative disorders to spinal deformities, spinal infections, spinal trauma and spinal tumours. He has accumulated vast experience in spinal surgery, having run a service for 10 years at Mid-Cheshire which dealt with more than 3000 OPD spine patients a year and he performed over 350 spine surgeries every year as well as a busy private practice in Cheshire, including patients from North Wales.
His surgical experience ranges from simple cervical and lumbar discectomies, to cervical and lumbar disc replacements, vertebrectomies, TESSYS, reconstruction for spinal trauma, spinal tumours and the full spectrum of spinal deformities. He audits every patient’s outcome and all his patients have to complete international protocols including Oswestry Disability Index, Canadian Neck Disability Index and his own Spinal Deformity Protocol, thereby ensuring full documentation for his patients.
He was invited by Apollo colleagues in 2011 to visit Delhi to do some complex spinal surgery. The patients were turned down at other Delhi hospitals and were extremely complex, of a kind rarely seen in the West as diagnosis and treatment in the NHS is done quite early due to the UK GP referral system. Both the complexity and the gratifying outcomes were life changing moments for him and he decided to return to Delhi in 2012, having turned down a senior consultant position in Singapore.
Special Clinical Interests
He has special interest in complex spine surgery including manubriosternotomy for upper thoracic anterior instrumentation, jaw splitting craniocervical surgery, total sacrectomy with lumbopelvic reconstruction, skull separation cervical osteotomy, complex revision of failed spine surgery and shape memory metal rod and staple instrumentation systems for spinal deformities. He developed his own techniques for Sacral Tarlov cysts and anterior long and short segment instrumented correction for pediatric and adult spinal deformities.
He is initiating basic science research into stem cell and growth factors for spinal cord injury,spinal deformity and disc disorders, in collaboration with Indian Council of Medical Research. His PHD background in molecular biology has stimulated this interest. He is of the view that India should be leading in research, given the volume and complexity of spinal disorders of every kind in our country. He hopes to develop non-destructive treatments for many of the common spinal disorders.
