Knee replacement 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. Knee replacement surgery is safe and effective and helps relieve the pain. It also restores the function of the knee joint, thereby helping in movement.
What Was Done to my Knee During my Total Knee Replacement Surgery?
A knee replacement surgery is performed under Spinal/general anesthesia.
Once the anesthesia is administered, the orthopedic 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.
The Best Position to Sleep at Night
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.
Walk as Soon as Possible
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 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 total knee replacement surgery and start to work on a PT plan. Some of the exercises after total knee replacement include -
Ankle Pumps - Lay flat on your back with your legs straight and move your ankles up and down.
Quadriceps Sets - Lay down on your back and tighten the thigh muscles pressing the back of your knees to the bed. Hold for a count of 5 and then relax.
Gluteal Sets - Lay flat on your back. Squeeze your buttocks together and hold for a count of 5. Relax.
Seated Knee Exercise - Sit erect in a chair. Now slowly straighten your operative knee. Return the leg slowly to the starting position.
Assisted Knee Bending - Sit erect in a chair. Now, slowly bend the operative knee as far as it will bend. 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.
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.
Working With a Physical Therapist after Surgery
You must enlist the help of a physical therapist following your surgery. This will help shorten your total knee replacement recovery time and help you gain full flexibility and function as soon as possible. The physical therapists at BLK Max Hospital will help you get back to routine activities in a gradually phased manner to avoid damaging or injuring the surgical prosthesis while allowing time for the site to heal.
Your doctor at BLK Max Hospital will recommend the length or duration of physical therapy needed; most patients require at least 4 weeks of formal physical therapy following the surgery.
To restore the functions and relieve the pain of the severely diseased knee joints, operate them with a knee replacement surgery. If you have a fear of pain after surgery, rest assured. It will never be excruciating or intolerable. With the help of an ice machine and compression socks, you can tolerate the pain.
