Newest and most exciting development in Joint Replacements is the use of Patient Specific Instrumentation

Says, Dr T Sringari, Trauma, Joint Replacement & Arthroscopic Surgeon, Paras Hospital Gurgaon in an interaction with Ekta Srivastava, Health Technology

Although joint replacement surgeries alleviate pain and restore functions, they are known for associated risks. What is your take on it?

Any intervention has its share of risks and so does joint replacement. The common risks are infection and blood clots in the veins of legs. However, we perform the joint replacements only in the modern operation theatres which are fitted with laminar airflow system. The air in the theatre is filtered by this system. This technology along with the antibiotics and other precautions has reduced this risk to a bare minimum. We also give medications to the patients to avoid the clots in the legs. These measures have made joint replacements one of the most successful set of surgeries in modern medical practice.

Is age a factor when it comes to knee replacements?

Joint replacements are done in degenerate painful joints which affect our activities of daily living. Usually the age related degeneration occurs in elderly population. However there is also another group of patients where wear and tear of the joint takes place irrespective of the age and cal also occur in young patients .This can be due to fractures involving the joint ,rheumatoid arthritis etc. the pain in such cases could be crippling and disabling. In such cases we advise joint replacements in younger patients also. There are newer implants and technologies which have longer life and are being performed in younger patients.

What are your main focus areas?

My focus area is assessment, diagnosis and management of degenerative joints and sports injuries. This includes joint replacements and arthroscopic surgeries along with other simpler modalities.

What new technologies are being introduced in the field of joint replacement?

The newest and most exciting development in joint replacements is the use of patient specific instrumentation. In this the instruments required for joint replacement are tailor made for the particular patient. The only disadvantage of this was the waiting for period for making the instruments which was anywhere between 3to 6 weeks. However now this has come down to 3 to 4 days. This would give better alignment, early recovery and longevity to the joint.

Tell us about your team here, and what are you able to achieve that wasn’t possible elsewhere?

Joint replacement is not the only solution to joint problDr T Sringariems. Even in osteoarthritis, there are   many other options before embarking on joint replacements. We are trained and recognized as regional surgeons rather than procedure surgeons. For example say my specialty is knee, I would advise and perform the required procedure on knee and the procedure surgeons are only specialized in either joint replacements or arthroscopies. So our advice is comprehensive to the problem of the patient.

As far as the procedures are concerned, we are performing every possible surgeries like total knee replacement, partial knee replacement, patellofemoral replacements, tumor prosthesis and redo surgeries. Technology wise we are performing the surgeries using patient specific instrumentation.

We are also performing autologous chondrocyte implantation where in the cartilage cells are harvested in laboratory and implanted in the cartilage defect. This is done in early stages of focal arthritis
