Technology is changing our lives continuously. Although total knee and hip replacement surgery is highly successful in our hand, yet we strive for technological advances that can make it better in terms of patient satisfaction, minimizing complications and further improving our functional results.
Over a period of time many advances were introduced successfully in knee & hip replacement surgery like Gender specific knee, newer materials like Oxinium in knee & hip replacement surgery are some examples.
Now you have Computers (Computer Navigation) to assist surgeons during the surgery to minimize errors. The other thing is minimally invasive total knee replacement surgery, where I can perform a surgery through a very small incision without compromising on the accuracy of knee replacement and also without damaging the most important muscle i.e. Quadriceps (Quad sparing).
The new thing on the block is Patient Specific Implants for Knee Replacement surgery. This technology gives us bone-cutting guides made after creating a computerized virtual model of patient knee based on MRI & Long Leg standing X-rays. They are very specific to a patient and his knees and provide us precision that we are looking for during the surgery.
Broadly speaking a knee replacement surgery can be carried out either through the traditional approach, or newer minimally invasive approach (MIS), also known as quadriceps-sparing approach.
It allows surgeons to insert the same artificial implant through a shorter incision.
This surgical approach avoids trauma to the quadriceps muscle, which is the most important muscle group around the knee, thereby allowing quicker recovery time including walking and knee bending movements.
The less-traumatic nature of the surgical approach may also reduce post-operative pain and diminish the need for rehab and therapy compared to more traditional approaches.
This technique is appropriate for majority patients, however needs expertise from your surgeon to prevent any wound complications or component Malalignment.
