Making The Knee Incision

Arthroscopic Knee Surgery | Meniscus Surgery Performed by Dr. Millstein

The surgeon makes an incision across the front of your knee to gain access to the patella, more commonly referred to as the kneecap. In a traditional knee replacement, the incision is usually about 8 to 10 inches long. In minimally invasive knee surgery, the incision is usually about 4 to 6 inches long. The jury is still out as to whether or not the pros of the smaller scar outweigh the cons of a smaller surgical area. Talk to your doctor about which procedure is right for you.

Your Recovery And Living With Your New Knee

You should be able to stand and move around one day post-surgery. Typically, patients begin physical therapy for their recovery by using parallel bars to practice walking. Next, you will transition to a walking device, such as crutches or a walker. After six to eight weeks, when your knee can support your body weight and after your body has built muscle strength, you should be able to perform most normal weight-bearing and low-impact movements and daily activities with little or no pain. You will need to avoid high-impact activities to prolong the lifespan of the joint prosthesis.;

Be sure to attend all follow-up appointments. As with any surgery, there is a risk of infection, blood clots, or other complications. Sometimes, the range of motion may be more limited than was expected, and knee scarring can occur. Additionally, over time, implant surfaces become worn and the artificial joint may loosen from use. Previously, a revision total knee arthroplasty would be needed around 10 years after the initial surgery. With current surgical techniques, knee implants have long-lasting lifespans of 15 20 years. ;

What Is A Knee Replacement Surgery

Knee replacement, also called knee arthroplasty or total knee replacement, is a surgical procedure toresurface a knee damaged by arthritis. Metal and plastic parts are used tocap the ends of the bones that form the knee joint, along with the kneecap.This surgery may be considered for someone who has severe arthritis or asevere knee injury.

Various types of arthritis may affect the knee joint. Osteoarthritis, adegenerative joint disease that affects mostly middle-aged and olderadults, may cause the breakdown of joint cartilage and adjacent bone in theknees. Rheumatoid arthritis, which causes inflammation of the synovialmembrane and results in excessive synovial fluid, can lead to pain andstiffness. Traumatic arthritis, arthritis due to injury, may cause damageto the cartilage of the knee.

How Is Total Knee Replacement Surgery Performed?

Following the computer imaging process, a 3D model of the patients knee is created, including the lower end of the thigh bone and the upper end of the shin bone . From this model, a 3D cutting block is designed and constructed to be used during surgery.

In surgery, that plastic cutting block would fit on the patients femur bone in a very specific way, says Dr. Desman. It just locks on; you can only put it in one way. The block has little holes that we put pins in to secure. Once secured and precisely aligned, were able to use the saw blade to give us the exact cut of the femur that we planned preoperatively.

The tibia has a similar cutting device, Dr. Desman continues. We use that piece in surgery, and it fits precisely on the patients bone, again locked in with pins through tiny holes in the implant. A slot on the device allows the saw blade to go through it and cut the bone in an exact way to make sure its perfectly straight. By making these cuts very straight, all the guesstimates of manual surgery are removed.

  • Reconstruction of a torn anterior cruciate ligament , which is a ligament that helps stabilize the knee joint
  • Removal of inflamed synovial tissue
  • Trimming of damaged articular cartilage
  • Removal of loose fragments of bone or cartilage
  • Treatment of patella problems
  • Treatment of knee sepsis
