Total Knee Replacement (TKR)

total knee replacement is also termed total knee arthroplasty. It helps to treat the worn-out or damaged surfaces of the knee joint by replacing it with an artificial metal or plastic prosthesis.

Total Knee Replacement Procedure

The surgeon will make an incision on the skin over the affected area of the knee to expose the knee joint. The damaged portions of the femur bone are cut using specialized jigs. Then, the femoral component is attached to the end of the femur with or without the bone cement. The damaged area of the shinbone and the cartilage is cut to remove the deformed bone, and the implants are attached. The tibial component is secured to the edge of the bone using a screw or bone cement.

Your surgeon will place an artificial surface between the implants to provide a smooth gliding surface for mobility. This will support the body’s weight and allow the femur to move over the tibia. On testing, the patella or the kneecap is glided smoothly with a smooth range of motion. After the procedure, the entire joint is cleaned with a sterile solution, and then the incisions are closed with a safe dressing.

Unicondylar / Partial Knee Replacement

Partial knee replacement is also known as unicompartmental or unicondylar knee replacement using minimally invasive surgery. It is done for patients with arthritis or if only a part of the knee joint has to be replaced through a small incision.

The knee joints are made up of three compartments that include the medial (inside), the patellofemoral (kneecap), and the lateral (outside) compartment. It is a surgical procedure that involves resurfacing or replacing the diseased or damaged surface of the joint instead of the entire joint.

Unicondylar / Partial Knee Procedure

During the procedure, a small incision is made to expose the knee joint. The surgeon will remove only the diseased part of the meniscus and place the implants into the bone by moderately shaping the shinbone and thighbone. The artificial component is placed into the new prepared area and then it is secured with bone cement.

The damaged part of the femur or thigh bone is ejected to adapt the new metal component to fix in the respective place using bone cement. When the femoral and tibial components are fixed, the knee can restore to routine movements. After the procedure, the muscles, and tendons are repaired and the cuts or incisions are closed.

Revision Knee Replacements

Revision knee replacement surgeries require replacing a part or all previous knee prostheses with a new prosthesis. The operation may range from minor adjustments to massive operations replacing significant quantities of bone and hence it is difficult to describe in full.

Revision Knee Procedures

In this knee procedure, the surgeon makes an incision over the knee and the knee cap along with its ligament is moved aside to make enough space to perform the operation. The old femoral component of the knee prosthesis is ejected and the femur is prepared to accept the new component. But in certain cases, the damaged bone is removed and a metal wedge or bone graft is used to make up for the lost bone.

Next, the tibial component with its old plastic liner is removed and the damaged bone is cut to prepare the tibia to receive the new component. Like the femur, the lost bone is replaced by either a bone graft or metal wedge. An unused plastic liner will be placed on the top of the tibial component.

In case if the patella or kneecap is damaged, the surgeon will resurface and attach a plastic prosthesis. The tibial and femoral components are then brought together using the prosthesis to form a new knee joint. Then, the knee muscles and tendons are attached by draining the excess blood and the incisions are closed with dressings.

Pre-Op & Post-Op Cours

Pre-Op Course

All knee procedures require medical clearance by an internist at HSS which must be done within 28 days prior to your surgery date. We will coordinate these appointments as well as an educational class.

We recommend stopping the use of all anti-inflammatory, fish oil supplements, and other blood-thinning medications one week prior to surgery. Your clearing doctor will make recommendations regarding other prescription medications.

Post-Op Course

Your hospital course will entail admission from 1-2 days. Once you are cleared by therapy you can be discharged to home with provided visiting nurse services and physical therapy services at home. This will be followed by outpatient Physical Therapy. Your initial follow-up will be six weeks postoperative.

On average your return to work recovery will be approximately six to eight weeks, depending on individual recovery. The majority of patients will be able to resume most sporting activities in twelve weeks post op.
