					Oxinium Knee Replacement For Young Patients With Osteoarthritis
Total knee replacement is generally performed in older patients with
osteoarthritis. For the first time in India, a new prosthesis for young
patients with osteoarthritis will be introduced. This prosthesis made of
a wonder material called Zirconium, a ceramic coated metal ensures longer
survival of the prosthesis after implantation. The introduction of this
prosthesis will hopefully encourage more number of young and middle aged
Indians and Westerners to undergo knee replacement in India.
Advantages of Zirconium
1) The significant advantage of Zirconium knee implants is that it is
considerably harder. On testing it lasts 85 times longer in tests that
simulate the stresses inside the actual knee. Additional advantages are
scratch resistance.
2) When it is wet, ceramic can glide smoothly along plastic, making for
smoother motion than with metal-on-plastic. As a result, the Oxinium
total knee replacement will not generate the quantity of plastic wear
debris that cobalt chrome will, and the implants should last considerably
longer. Zirconium is one of the six most biocompatible elements know to
man. So, your immune system will more easily tolerate your new implant.
3) Lastly, patients who are allergic to nickel, the metal most often used
in the current implants, cannot currently receive total knee
replacements. The ceramic implant, however, can be implanted safely in
patients with nickel allergies, since it uses a zirconium alloy with no
nickel. Implants made of Oxinium have been implanted in larger number of
patients in the UK Australia and the US with great success.
Who would benefit most from an Oxinium (zirconium) total knee
replacement?
Three types of patient have been identified as the "best" candidates for
an Oxinium total knee replacement.
"Younger" patients: Because Oxinium knee implants offer significantly
less wear compared to cobalt chrome implants, they are expected to last
considerably longer. In the past, orthopedic surgeons have advised
patients less than 65 years of age to wait to have knee replacement
surgery because the life span of the cobalt chrome knee implants is only
10-15 years. Now, surgeons have a viable option for a younger patient who
previously would not be a candidate for a total knee replacement because
the Oxinium knee implants should last much longer. Therefore, a patient
under the age of 65 who has advanced arthritis of the knee no longer has
to suffer for years until he reaches an appropriate age for total knee
replacement surgery.
"Active" patients: Patients, who desire to return to an active lifestyle,
including sports, dancing, gardening, or other strenuous activities, may
also benefit from an Oxinium knee replacement. As a result of their high
activity level, this patient population will put more "wear and tear" on
their knee replacement, which can cause the implants to wear more
quickly. An Oxinium knee is better able to tolerate this high activity
level and last longer that the traditional cobalt chrome knee. Metal
allergy patients: Because Oxinium is one of the most biocompatible
materials known to man, it is the only choice for patients who exhibit
metal allergies. Patients who have needed total knee replacement surgery,
but could not tolerate the cobalt chrome implants due to their nickel
content, can now have the surgery they need to return to an active
lifestyle without the fear of an allergic reaction.
The first patient will be a middle aged Housewife with osteoarthritis.
Whereas normal knee prostheses cost about 80,000 rupees, this new
prosthesis may cost about 1. 25 lakhs, but it is comparable to the best
in its category. The higher cost will be offset by the longer
survivorship of the implant. A Total knee package is available for
Indians and foreigners with normal and long life prostheses at affordable
costs.
Dr.A.K.Venkatachalam, MS, DNB, FRCS (UK), MCh. (Liverpool) has worked
with leading Knee surgeons in the UK, Belgium and Dubai earlier. He is
affiliated to the Chettinad health city hospital in Chennai. Recovery
from surgery is no longer a painful ordeal as expert anesthetists provide
effective anesthesia and pain relief to inpatients. The intensive care
unit is monitored by alert physicians round the clock and multi specialty
referrals are readily available. There are well qualified
physiotherapists to help you recover quickly from surgery.
Our track record
We have had the pleasure of treating patients from the USA, UK,
Bangladesh recently and these numbers are increasing. Knee replacements
are performed using the most modern techniques and prostheses. Amongst
others the following procedures are routinely performed.
Knee
Total knee replacement- normal and high flexion
Unicondylar knee replacement
Arthroscopic ACL reconstruction
Cartilage surgery
Osteotomy for osteo arthritis and knee cap problem
Fracture
