Partial And Total Knee Replacement Surgery

Hi!

This is Dr. Hitesh Kubadia, I’m an orthopedic and joint replacement surgeon, specializing in minimally invasion joint replacement surgeries using the muscles sparing approach. I also do a lot of partial knee replacement i.e. called a unicompartmental knee replacement which is the next thing in trying to preserve as much as natural tissue as possible.

I’m here to explain something about osteoarthritis of the knee which is a very common problem faced by lot of elderly population and it disabled them in day to day life. These are the small models of the knee here so that I can explain it to you all and you all can understand what is the actual problem here. Now if you look at this is the knee model so if you look at the knee the knee is made up of a lower portion of the femur and upper portion of the tibia, so this is covered by a cartilage here, this blue thing which is marked up here is the cartilage and this is a very smooth glistening surface which allows for frictionless movement across the knee. OK.

As we age as we creates strains in this cartilages, these cartilages develop some bumps in their surfaces. So this surface doesn’t become as smooth as it once was. As we age as the friction keeps on increasing with a period of time this gets worn out completely. So much so that the underline bone gets starting visible and this causes tremendous frictions on your movement and causes pain. As people still pull on and then what happen this all the 3 compartments of the knee, the medial compartment, the latter compartment and the front compartment and the inner compartment the outer compartment and the compartment which is in the front all get worn out.

.So this causes pain and disability and pain for the patient and effects the day to day activities of life. Osteoarthritis has various forms of treatments, initially, everything is nonsurgical so when you try all those non-surgical methods to relief so that your life continues with lot of more than ease. But when these non-surgical methods like injections in the knee or physical therapy and injections in the knee start failing to give you enough relief then we need to think about surgical options.

So when we see on the x-ray on the clinically examine the patient and we see only one compartment of the knee which is damaged and the other part of the knee is very healthy it makes sense to do only you know change only that compartment of the knee which is actually causing the problem for the patient. So what is done here, as you look at this model is the friction between only in this compartment of the knee the other compartment of the knee is nice and smooth so what is done is only this compartment is changed. So what is changed with is you just resurface the area which is actually damaged and the resurface the lower portion that is damaged so which we removed this portion of the lower portion of the tibia and what is replaced by a small alloy of cobalt chrome and other cobalt chrome alloy at the plate this plate and medical grey plastic is inserted between the two surfaces and this movement becomes more than glistening over the period of time.

So this gives relief and gives fantastic relief again this is a minimally invasive surgery and since all the ligaments and the part of the knee is preserved and they are natural and they are glistening so the feel of the knee is much more natural and we have now enough reports across the world. These things lasting for even 20 years there is actually slowly passing the results of a traditional total knee replacement. We just spoke about the partial knee replacement but when we see the arthritis is confined to all the three compartments so this is no point in changing only the one part of the knee so that’s we come to the total knee replacement. So that’s what gives the patient long-term relief.

Again this done through a minimally invasive approach, muscle sparing approach so that the recovery time is much faster and much shorter. Right! So here we look at this model see this the whole knee is damaged the inner compartment the outer compartment the whole knee is damaged. So what is done here? Again resurfacing part so only the damaged portion of the cartilage and bit of bone is removed like this and we changed the whole thing off, and this is replaced with a cobalt chrome allow base plate and a medical grey plastic. Again on the femur side again cobalt chrome alloy which is fitted across. This is fitted to the bone with bone cement and this gives you lasting movements and comfortable movements across life.
