Latest Techniques for Knee replacement surgery in India
Attune Rotating Platform knee replacement along with Minimally Invasive Subvastus technique is a boon alleviating all the fear in the patient. This surgical procedure makes the patients feel their knee is a normal knee in regards to stability, mobility and function. Versatility in size and matching the patient’s anatomy makes this a – Personalised Knee. In other words, the custom made knee is now ready made. There is no time loss and no need for CT scan thus averting the radiation exposure – which is mandatory in the case of a custom made knee.This kind of surgery also uses patented technologies like Gradius curve and Softcam, which helps in enabling smooth and stable flexion and extension of the knee joint without any abrupt jerks, removing the patient’s traces of pain and discomfort in the area.The functional durability and longevity of this knee is likely to be more than 30 years and it is very much suitable for patients between 45-55 as well as for obese patients.The Minimally Invasive Subvastus technique differs completely from the conventional technique. In the conventional surgery the skin is cut 15-20cm along with the muscles in front of the knee and thigh, the knee cap is flipped and the thigh and leg bones are separated from each other to perform the conventional surgery resulting in prolonged post operative pain and recovery. Whereas in the Minimally Invasive Subvastus technique the skin is cut only 8-10cm.The muscles are preserved by pushing them to the side without cutting them. The knee cap is not flipped and the thigh and leg bones are not separated but are cut in place. All these resulting in less pain and quick recovery.
The combined benefits of the new implant and the surgical technique make this procedure as the ‘Ideal Total Knee Replacement’ for patients who are waiting for it.
In short, patients can get back to their everyday activities they love to do, more comfortably and confidently within a month or two.
This latest advancement provides painless operation and eliminates all side effects of the traditional knee surgery by utilizing Hi-flexion implants, after the surgery, which ensures that the patients will receive full flexion like the healthy knee joints they use to have.
the new technology PSI (patient-specific instrumentation), which improves alignment and sizing by using computer-generated images of the patient anatomy to determine precise bone cuts and implant positioning during the surgery.
The advanced knee surgery enables lesser surgery time, lesser post-operative complications and recovery.
Unlike the conventional knee replacement surgery, PSI reduced the blood loss during and after surgery and serious complications. As many operative steps are reduced in the technique, and excessive dissection is not required, the operative time or the knee replacement procedure which takes about three hours was reduced by half due to this new method
Indian doctors have carried out Bicruciate Substituting (BCS) Knee Replacement surgery in which an advanced implant is used to restore the normal motion of a knee, ensuring a more natural movement than that achieved by conventional surgery.
The advanced technique for knee treatment was introduced in the presence of Alfred Tria, Chief Orthopaedic Surgeon from St Peters University Hospital, New Jersey who is the designer of the implant.
In the current knee replacement procedure, doctors have to cut the cruciate. Doctors cut both the ligaments but substitute the function of only one which results in a kinematic confict and the knee movement is not natural.
BCS knee replacement implant has two important features-firstly it has a distinct design which allows the near natural movement of the knee and secondly it is made of a material combination which has been shown to be durable in laboratory testing.
Made up of oxinium and zirconium with an oxidised surface, the durability of this implant is 30 years contrary to the current implants which have a durability of 15 years.
Also, women may be allergic to some of the components used in the conventional knee replacements because of the presence of nickel and cobalt. The metal allergy can cause pain and early failure of the artificial joint. One of the advantages of oxinium is that it doesnt cause allergy.
Advancements in Knee Surgery:-
Gender Specific Knee Replacement (females) – Zimmer Implant :-Specially suited for the female body due to significant differences in anatomy of men and women.
High Flex Knee Replacement :- Bending upto 155 degree and permits kneeling, cross legged and squatting.
Minimal invasive knee Surgery: – incision of four to five inches only. small scar, less blood loss, less surgical trauma, less post operative pain, lesser medication, fast recovery, shorter hospital stay.
