Total knee replacement (TKR surgery) also referred to as Knee Arthroplasty, is a surgical procedure done to replace bone and cartilage, damaged by conditions such as osteoarthritis or injury, with a prosthesis. This surgery is considered after medication, physical therapy, and exercise have failed to provide relief. Total knee replacement (TKR) surgery is safe and effective and helps relieve the pain. It also restores the function of the knee joint, thereby helping in movement.
If we look at the statistics, around 70,000 to 80,000 knee replacement surgeries and 20,000 to 30,000 hip replacement surgeries are carried out every year, suggesting that people suffering from arthritis are becoming more aware of surgical treatment options. During the early stages, medication and walking support can prove helpful, but what are your options when the condition of your arthritis has extensively severed? Well, you don’t have to worry because you certainly have great treatment options like Total Knee Replacement (TKR) Surgery to look forward to.
What Does Total Knee Replacement Surgery Encompass?
A lot of people suffering from arthritis lose all hope when their doctor tells them about the extreme destruction of their knees. But little do they know about their treatment options. Total knee replacement surgery is one of the most effective treatment options available. Total knee replacement (TKR) surgery improves the functioning of the knee considerably. It has come as a new hope in the lives of people suffering from arthritis.
Types of Total Knee Replacement Surgery
High Flex Total Knee Replacement
Unlike the conventional implants that allow knee flexion of around 120 to 125 degrees, high flex implants allow increased flexion of about 150 to 155 degrees, thereby giving you a better range of motion and allowing you to perform activities like climbing stairs, squatting, kneeling etc. Owing to the fact that high flex implants are slightly modified to give better flexion, there is a need of 2-4 mm of additional bone resection.
Oxinium Total Knee Replacement
The prosthetic femoral components used in full knee replacement surgery are usually made up of metals like cobalt-chromium with plastic as an articulating surface. However, gradual wear and tear can result in the roughening of the upper surface of the implants and the plastic surface starts to wear out resulting in suspended implant debris in the surrounding areas. This can lead to aseptic loosening. In such cases, using an Oxinium implant is the best option. Use of oxidised zirconium (OxZr) has helped to reduce the incidences of wear and tear by 85 per cent.
Revision Total Knee Replacement
As the name suggests, it is a TKR revision surgery that is performed to replace an existing prosthetic joint, or a part of it, which has been damaged by excessive wear and tear or an accident or injury. Revision knee replacement procedure is similar to primary total knee replacement. Revision knee replacement surgery may also be performed in case of chronic infection at the site of the primary implant.In such cases, the surgery is performed in two different steps which involve the removal of the primary implant and placement of an antibiotic spacer block which is kept there for 6 to 12 weeks. The antibiotics present in the spacer help to clear the infection, after which another surgery is performed to place the new implant.
Minimally Invasive Total Knee Replacement Surgery
The integration of medical science and technology is leaving no stone unturned to relieve patients from their pain. With the intervention of the latest techniques like computer navigation, total knee replacement surgery (TKR surgery) has improved way beyond our imagination. Using these technologies, surgeons are now able to perform pain-free surgeries with great precision.
Not only this, but patient experience has also improved with shorter hospital stays, lesser rehabilitation time, and most importantly reduced pain. An important point to note here is that not only the best knee replacement surgeons but also patients are required to be educated about these procedures as it will help them to collaborate better.
Partial Knee Replacement
In some cases where only a small part of the patient’s knee joint has been damaged, it is futile to replace the whole knee joint. Hence partial knee replacement is the best treatment option for such patients. The procedure involves the replacement of only the damaged part of the joint with a new prosthetic component. The doctor will make an incision on your knee to access the affected joint and the damaged bone and joint debris are removed. A small metallic or plastic component is cemented in its place and the wound is closed.
Preparation For Total Knee Replacement Surgery
What was Done to my Knee During my Total Knee Replacement (TKR) Surgery?
- When a surgeon commences TKR knee replacement, the safety of the patient is his major concern. The patient bestows his trust in the skills of the surgeon and hence, it becomes important for him to keep up that trust. A good surgeon not only treats his patient effectively but also indulges in an open conversation telling him about the adeptness of the technology used in his treatment and the possible risks involved, further enhancing the transparency between them.
- Total knee replacement surgery (TKR surgery) is performed under Spinal/general anesthesia.
- Once the anaesthesia is administered, the orthopaedic surgeon from BLK-Max Hospital will make an incision and remove the damaged surfaces of the knee joint. This could involve cartilage or bone that has undergone degeneration due to disease or injury. These will be replaced with knee prosthesis made from high-grade polymers or metal alloys.
- The prosthetic knee is attached to the bone and cemented with surgical-grade cement.
- The incision is then closed, and a drain may be placed to remove excess fluid.
Recovery After Total Knee Replacement Surgery
The Best Position to Sleep at Night After TKR Surgery
It is common to expect some pain and soreness immediately following surgery. Most patients take up to 6 weeks to return to normal activities and it may take about 6 months to a year to gain the full benefits of the knee replacement surgery. In the meanwhile, it is important to take the precautions that your doctor recommends. The best position to sleep in is on your back. This allows the leg to stay extended and ensures proper blood flow to the surgical site. You may want to prop up your leg with a rolled-up towel or soft pillow while sleeping.

Within three weeks, you can walk without crutches. In the starting, walk for 10 minutes. Gradually with the help of your physical therapist, you can push more.
Exercise to Perform Right After Total Knee Replacement Surgery
Regular breathing exercises, thigh squeezing, knee straightening, moving feet up and down, etc., can be performed.
Best Way to go up and down the Stairs with my cane
- After a total knee arthroplasty surgery, you may be asked to avoid the stairs for a few days.
- Then, as you start to use the cane for support, you will need to go up and down the stairs slowly.
- Hold the banister or the railing with one hand and the cane with the other. Climb up with the non-operative leg and bring the other to join it before you take another step up.
- While climbing down, use your operative foot to step down and bring the other to join it. As your flexibility and strength increase, you may start alternating one step per foot.
Your physical therapist will meet you within 24 hours of your knee TKR surgery and start to work on a PT plan. Some of the exercises after total knee replacement (TKR) include:

- Assisted Knee Straightening: Sit erect in a chair. Now, slowly stretch the operative knee as far as it will go. Use your other leg to support it. When you feel a mild stretch hold for a count of 5 and return to the starting position.
