What is the Total Knee Replacement (TKR)?
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 the patient’s body. A Total knee replacement procedure is among the safest and most effective of all standard orthopaedic surgeries, remaining the only resolutive treatment of a damaged knee.
How is it performed?
Essentially, the surgery is a four-step process. The first part involves preparing the bone by removing the damaged cartilage surfaces at the ends of the thighbone (femur) and shinbone (tibia), as well as a thin portion of underlying bone.
Some relevant statistics
The American Academy of Orthopaedic Surgeons reports that:
Also, one recent study found that more than 95% of patients report that they are satisfied with the outcome of their total knee replacements one year after surgery—the highest rate for any type of major orthopaedic surgery. Other studies have found that 92% of patients believe they have made the right decision.
Which are the risks?
The patients should be aware that there are risks are associated with a TKR. These risks include:
In addition, early implant loosening or failures can occur—especially if misalignment occurred between the implant and the bone during surgery or afterward. Although these failures are uncommon, and usually occur in the weeks following the original surgery, they would require a return to the operating room for a revision surgery.
During this revision procedure, the surgeon removes the failed implant, once again prepares the bone, and installs a new implant.
How should the patients be prepared?
A TKR also requires an extended rehabilitation program and home planning to accommodate the recovery period. The patients should plan on using a walker, crutches, or a cane immediately after surgery.
Types of Total Knee Replacement Surgery
There are two different variations of a TKR. Every patient should speak to their doctor about which approach is best for his/her particular case.
What is the Partial Knee Replacement (PKR)?
This procedure (sometimes referred to as a uni-compartmental knee replacement) is an option for a small percentage of patients. According to data from the Centers of Medicare and Medicaid Services (CMS), less than 10% of knee replacement surgeries in the US are partial knee replacements. As the name implies, only a part of the knee is replaced in order to preserve as much original healthy bone and soft tissue as possible. These patients generally have osteoarthritis in only one compartment of their knee. Therefore, surgery takes place in any of three anatomical compartments of the knee where diseased bone presents the most pain:
How is it performed?
During this procedure, a surgeon removes the arthritic portion of the knee—including bone and cartilage—and replaces that compartment with metal and plastic components. A PKR surgery offers a few key advantages, including a shorter hospital stay, faster recovery and rehabilitation period, less pain following surgery, and less trauma and blood loss. Compared with those who receive a TKR, patients who receive a PKR often report that their knee bends better and feels more natural. However, there’s less assurance that a PKR will reduce or eliminate the underlying pain, and since 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.
Surgeons usually perform PKRs on younger patients (under the age of 65) who have plenty of healthy bone remaining. The procedure is performed on one of the three knee compartments. If two or more knee compartments are damaged, it is probably not the best option. PKRs are most suitable for those who lead an active lifestyle and might require a follow-up procedure—perhaps a TKR—in 20 years or so, after the first implant wears out. However, it is also used for some older individuals who live relatively sedentary lifestyles.
What Should the Patients expect after the PKR?
Because partial knee replacement is less invasive and involves less tissue, you are likely to be up and about sooner. In many cases, a PKR recipient is able to move around without the aid of crutches or a cane in about two to three weeks—approximately half that of a TKR patient. They also experience less pain and better functionality—and report high levels of satisfaction.
Types of Knee Replacement Approaches
The patient’s doctor will also choose a surgical approach (as well as the approach to anaesthesia, >90% regional) that’s best suited to his/her needs. The patient and the medical team will engage in pre-operative planning that covers the type of procedure that will be undergone and associated medical requirements. In order to ensure a smooth procedure, a skilled orthopaedic surgeon will map out the patient’s knee anatomy in advance so that he or she may plan their surgical approach and anticipate special instruments or devices. This is an essential part of the process.
Which are the possible knee replacement procedures?
In the traditional approach, the surgeon makes an eight- to 12-inch incision and operates on the knee using standard surgical technique. Generally, the incision is made along the front and toward the middle (midline or anteromedial) or along the front and to the side (anterolateral) of the knee. The traditional surgical approach usually involves cutting into the quadriceps tendon in order to turn the kneecap over and expose the arthritic joint. This approach typically requires 3 to 5 recovery days in the hospital and about 12 weeks of recovery time.
Minimally Invasive Surgery (MIS)
A surgeon may suggest a minimally invasive procedure that reduces trauma to tissue, lessens pain, and decreases blood loss—consequently speeding recovery. A minimally invasive approach reduces the incision to 3 to 4 inches. A key difference between this approach and the standard surgery is that the kneecap is pushed to the side rather than being turned over. This results in a smaller cut into the quadriceps tendon and less trauma to the quadriceps muscle. Because the surgeon cuts less muscle, healing occurs faster and you are likely to experience better range of motion after recovery.
The procedure modifies the techniques used in traditional surgery while using the same implants from traditional surgery. Manufacturers provide specialized instruments that help to place the implant accurately but also allow for incisions to be made as small as possible. Since the only change between MIS and traditional surgery is in the surgical technique, the long-term clinical outcomes are similar.
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 quadriceps-sparing method, as the name suggests, is less invasive than traditional surgery. It spares the quadriceps muscle from as much trauma as possible.
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).
Another variation of a quadriceps-sparing approach is called midvastus. It also avoids cutting the quadriceps tendon, but instead of completely sparing the vastus muscle by going under it, in this surgical approach the muscle is split along a natural line through the middle. The decision to use one approach versus another depends on the condition of your knee and surrounding tissues.
The subvastus and midvastus approaches often take longer to perform but may result in a faster rehab process because there is little to no trauma to the underlying thigh muscle, making it easier to walk sooner after the operation.
This approach is rarely used. It is more common for patients whose knees tend to bend outwards. The surgeon enters the knee joint laterally, or from the side of the knee. 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.
Minimally invasive surgery trims the hospital stay to 3 to 4 days and it can shorten the recovery period to four to six weeks. One study found that patients in this group experienced less pain and were able to resume daily activities faster and better than patients who had standard surgery. At one year, however, there were no significant differences between the two groups.
Minimally invasive approaches are not appropriate for every patient. Surgeons carefully evaluate each patient and select the approach that is the best. Also, minimally invasive surgery is more difficult to perform and requires a more specific technique, instruments, and surgical training. One study found that it requires about one hour longer than a traditional surgery.
The knee replacement surgery is very effective and successful and, in order to find out which is the method that best fits your needs, it's advisable to contact a specialized team of professionals.
