Total Knee Replacement
Total Knee Replacement (TKR), also called as arthroplasty is a surgical procedure considered for patients whose knees have been damaged by progressive arthritis. During the ‘life-changing’ procedure, the surfaces of the ‘thigh’ bone and bone of the ‘shin’ which connects to the knee are removed and replaced with an artificial joint.
The surgery is also considered for patients with a severe knee injury, age-related osteoarthritis, or other rare destructive diseases of the joint. It provides relief from disabling pain and restores the function of the knee joint thereby allowing patients to lead a pain-free and normal life.
However, Total Knee Replacement Surgery is now among the safest and most effective of all standard orthopaedic surgeries and with advancements in medical technology, the procedure can now be performed with a small incision, at a short duration, and with almost no pain.
Conventional Total Knee Replacement
Usually, when your knee fails to respond to medications and other alternative treatments, knee replacement surgery is the best available option. During the conventional surgery, the surgeon removes the surface of your bones that have been damaged by osteoarthritis or other causes with the help of special surgical instruments and replaces the knee with an artificial implant that glides easily and mimics the motion of the natural knee.
However, during the traditional or conventional knee replacement, the repair and recovery may require a longer hospital stay and physical therapy. Otherwise, there’s no difference between minimally invasive and conventional knee replacement in terms of pain, walking speed and other measures of function during the recovery period.
Computer-Navigated Total Knee Replacement
Computer-navigated total knee replacement surgery has evolved over the years. Unlike the conventional surgery, in computer-assisted knee replacement procedure, computer navigation uses software that helps the surgeon to outline the deformity and plan accordingly to perform bone cuts and ligament balancing with absolute precision.
Most importantly, it helps in sizing the appropriate size and proper rotation of the component so that it fits the best. This results in a well balanced and well-aligned knee joint, which obviously lasts longer. A smaller incision (minimally invasive), less blood loss, faster rehabilitation are other advantages of computer-navigated total knee replacement.
Robotic Total Knee Replacement
Robotic Knee Replacement Surgery is an advancement to the computer-assisted surgical procedure which relieves patients suffering from degenerative knee diseases such as osteoarthritis. It utilizes a CT scan to generate a 3-D model of the patient’s knee joint which aids the surgeon in planning the surgery.
The procedure uses robotic-arm technology that allows the surgeon to perform the surgery through a smaller incision with utmost precision. Besides, the robotic software provides dynamic information which assists the surgeon in precise placement of the implant and thus, enhances the accuracy of the surgery. Some of the other advantages of Robotic Assisted Knee Surgery include: it’s less complicated, offers quick recovery, and therefore, it requires a shorter hospital stay. Overall the accuracy and precision of a robotic-assisted surgery are unmatched.
Partial Knee Replacement
Partial Knee Replacement (PKR) surgery, also known as a unicompartmental knee replacement, is an option for people with moderate deformity of the knee caused due to either joint disease or post-traumatic arthritis. As the name implies, only a part of the knee is replaced during the surgery so as to preserve as much original healthy bone and soft tissue as possible.
Basically, PKR is advisable for patients who have osteoarthritis in only one compartment of their knee. So, the implant is inserted in any of three anatomical compartments of the knee where diseased bone presents the most pain. A PKR surgery is usually performed on younger patients (below 65 years), and it offers a few key advantages, including a shorter hospital stay, faster recovery, and rehabilitation period, less pain following surgery, less trauma and blood loss.
