Day 7 of Knee Osteoarthritis treatments from a Fellowship Trained Orthopedic Hip and Knee Subspecialist in Delray Beach Florida.
Please evaluate your specific condition with your doctor prior to starting any treatment. This advice is for educational purposes only.
Today we have reached the top of the ladder of treatment for knee osteoarthritis, the Total Knee Replacement. When the pain from osteoarthritis advances to the point where you are no longer able to do the things that you want to do on a daily basis where the conservative measures are no longer helping, then it is time to consider a total knee replacement also known as a total knee arthroplasty. This surgery shaves about 9mm of the end of the thigh bone (femur), the top of the shin bone (Tibia), and in some cases the back of the kneecap (Patella). Then metal implants are placed that match the amount of bone that was removed. A plastic liner goes in between the metal implants and a plastic button is placed on the back of the kneecap. Therefore there is no more bone touching bone which is why the surgery relieves the pain. This is a very successful operation with 80 to 85% of patients having no pain after they recover. It improves pain, function, and quality of life which is why I chose this profession, because patients do so well after they have this procedure.
I get asked a lot about the recovery process for a total knee replacement. It has really changed since the Covid pandemic. Now we are able to send most patients home the same day of surgery. We do this by using better anesthesia techniques, medications that help to minimize blood loss, and medication and diet protocols to allow for improved immediate recovery. The anesthesiologist will typically provide a nerve block to help numb the knee area. I will also perform multiple injections in the knee during the surgery to help with pain. The patient is then sent home with a home therapist and home nurse and in some cases a home health aid. The patient is then able to do physical therapy at home. On average a patient needs to use a pain pill or narcotic and use a walker for about 3-4 weeks after a total knee replacement. Patients are now able to shower almost immediately due to improved dressings which are also anti-microbial. Most patients will feel "back to normal" by three months after a knee replacement. These numbers are averages and I have had patients come at 2 weeks in no pain and using no walkers or canes. Every patient is different.
Total knee replacement is considered intermediate surgery and with any surgery there are some risks to consider. This list is not meant to scare you from surgery but it is important to know things that may happen but also to know that the risks from knee replacement surgery are uncommon. Risks include infection, damage to nerves, blood vessels, or musculoskeletal structures, fracture, pain acute or chronic, stiffness, need for assistive devices like canes, or walkers, dislocation, difficulty walking, wound complications, and medical complications such as heart attacks, strokes, blood clots in the legs or lungs, bleeding and need for transfusions, and death. This list is neither inclusive or exclusive but gives a good idea of the possibilities but also knowing that they are uncommon.
Given the complexity of the surgery, especially if a complication occurs, it is important to have a qualified surgeon. The best type of orthopedic surgeon for a knee replacement is one who has had fellowship training in hip and knee replacement procedures where they spent an entire year focusing on just these surgeries. This is known as a fellowship in Adult Reconstruction. Fellowship trained Adult Reconstruction surgeons, like Dr. Zavoyski, can handle most if not all possible complications that can occur from these procedures. In fact doctors send Dr. Zavoyski complicated situations so that he can address the problem and provide solutions.
Another option to consider is robotic assisted knee replacement which Dr. Zavoyski also performs. The robots assists in the surgery to make sure that the prosthesis is positioned as best as possible with millimeter accuracy. If you are considering a robotically assisted total knee replacement, Dr. Zavoyski does have specialized training in this procedures as well.
There are many advantages to Total Knee Replacement. I truly enjoy seeing how patients improve through their recovery and especially when they come to the office smiling because their pain is gone.
