A surgeon may suggest a minimally invasive surgery (MIS) that reduces trauma to tissue, lessens pain, and decreases blood loss — consequently speeding recovery. During the next phase, the surgeon positions the metal tibial and femoral implants and either cements them to the bone or press-fits them. Today’s procedures are increasingly sophisticated and safe. You should plan on using a walker, crutches, or a cane immediately after surgery. Your home should be ready for your recovery period before you undergo total knee replacement surgery. During a PKR, a surgeon removes the arthritic portion of the knee — including bone and cartilage — and replaces that compartment with metal and plastic components. And because the preserved bone is still susceptible to arthritis, there’s also a greater chance that follow-up TKR surgery may be required at some point in the future.

There are four main types: Total knee replacement is the most common type. However, it’s critical to set proper expectations and avoid high-impact activities such as running and skiing. These questions will help you prepare for your appointment and get the…, Knee replacement surgery is effective, but it can be costly, and recovery takes time. In order to ensure a smooth procedure, a skilled orthopedic surgeon will map out your knee anatomy in advance so that they may plan their surgical approach and anticipate special instruments or devices.

It is not a substitute for professional medical advice, diagnosis or treatment and should not be relied on to make decisions about your health. The software provides the surgeon with a more precise, computer-aidedimage of the knee. So surgery takes place in any of three anatomical compartments of the knee where diseased bone presents the most pain: the medial compartment located on the inside of the knee, the lateral compartment on the outside of the knee, or the patella femoral compartment that’s positioned on the front of the knee between the thighbone and kneecap. The lateral approach is less invasive than traditional surgery because it spares much of the quadriceps, making it easier for patients to return to walking faster. The traditional surgical approach usually involves cutting into the quadriceps tendon in order to turn the kneecap over and expose the arthritic joint. You and the medical team will engage in pre-operative planning that covers the type of procedure you receive and associated medical requirements. A TKR is now among the safest and most effective of all standard orthopedic surgeries. Often, this is nothing to worry about, but it can be a sign of osteoarthritis or an injury. on Types of minimally invasive approaches include: After making a minimal incision, the surgeon shifts the kneecap to the side and cuts away the arthritic bone without cutting through the quadriceps tendon.

The different types are categorized by the materials that rub against each other when you flex your knee: Metal on plastic. on This is an essential part of the process.

This is because there is little to no trauma to the underlying thigh muscle, making it easier to walk sooner after the operation. About 85 to 90 percent of TKR implants continue to work well 15 to 20 years after the operation. In order to ensure a successful outcome, the surgeon must align the implants precisely and carefully fit them to the bone. Why would I need knee replacement surgery? If you think you may have a medical emergency, immediately call your doctor or dial 911. What Are the Treatment Options for Hip Arthritis? The subvastus and midvastus approaches often take longer to perform but may result in a faster rehab process.

Reviewed Reviewed This approach is rarely used. During a TKR, a surgeon removes the surface of your bones that have been damaged by osteoarthritis or other causes and replaces the knee with an artificial implant that is selected to fit your anatomy. The traditional method for repairing a damaged knee is a total knee replacement surgery (TKR). At The Bone & Joint Center, our compassionate orthopedic specialists provide a wide range of services including orthopedic surgery, shoulder replacement, hand surgery, shoulder scope, hip replacement, knee replacement, joint revision, minimally invasive procedures, ligament reconstruction, physical therapy, and occupational therapy. Since the first operation in 1968, doctors have dramatically improved the procedure. From: Candidates for this type of surgery generally have osteoarthritis in only one compartment of their knee. There’s no cure, but treatment can help manage symptoms. Because a PKR is less invasive and involves less tissue, you are likely to be up and about sooner.

Types of Knee Replacement Implants. How do weight and exercise affect osteoarthritis? The decision to use one approach versus another depends on the condition of your knee and surrounding tissues. The surgeon uses special surgical instruments to cut away the arthritic bone accurately and then shape the healthy bone underneath to fit precisely into the implant components. The quadriceps-sparing method, as the name suggests, is less invasive than traditional surgery. Total knee replacement is the most common type. When your knee doesnt respond to medications and treatments, knee replacement surgery is an option. The procedure modifies the techniques used in traditional surgery while using the same implants from traditional surgery. Since the only change between MIS and traditional surgery is in the surgical technique, the long-term clinical outcomes are similar. Another term for this approach is “subvastus” because access to the joint is taken from under (sub) the vastus muscle (the largest part of the quadriceps muscle group). Partial knee replacement (PKR), sometimes referred to as a uni-compartmental knee replacement, is an option for a small percentage of people. Speak to your doctor about which approach is best for you. Complex (or revision) knee replacement is for those with very severe arthritis or who have already had more than one knee replacement surgery.

on. A computer-based approach also allows a surgeon to operate with a smaller incision and benefits the patient by reducing recovery time.

Removal of the posterior cruciate ligament (posterior-stabilized). Partial knee replacement may be an option if arthritis affects only one side of your knee and you have strong knee ligaments. Minimally invasive surgery trims the hospital stay to three to four days and it can shorten the recovery period to four to six weeks. In fact, advancements in medical technology have led to precise and highly functional artificial knee implants that nearly duplicate the way the human knee moves — and are custom fit to your body.

What’s Knee Replacement Surgery? Another variation of a quadriceps-sparing approach is called midvastus. Healthline Media does not provide medical advice, diagnosis, or treatment. ", American Academy of Orthopedic Surgeons: “Knee Replacement Implants.”, Cleveland Clinic: “Total Knee Replacement.”. What are the different designs in knee replacement surgery? This approach typically requires three to five recovery days in the hospital and about 12 weeks of recovery time. A key difference between this approach and the standard surgery is that the kneecap is pushed to the side rather than being turned over. A TKR also requires an extended rehabilitation program and home planning to accommodate the recovery period. If the ligament can support an artificial knee, the surgeon may leave the posterior cruciate ligament in place when implanting the prosthesis. However, there’s less assurance that a PKR will reduce or eliminate the underlying pain.
