Knee pain and stiffness can significantly affect your daily activities, making it difficult to enjoy your hobbies or even perform simple tasks like climbing stairs or walking. While physical therapy, medications, and other non-surgical treatments can help alleviate pain and improve knee function, some cases may require more aggressive treatment options. In such cases, a total knee replacement (TKR) may be the best solution.
What is a Total Knee Replacement?
A total knee replacement, also known as knee arthroplasty, is a surgical procedure that involves removing damaged cartilage and bone from the knee joint and replacing it with an artificial joint made of metal and plastic components. The goal of a total knee replacement is to alleviate pain and restore knee function, allowing patients to perform daily activities with greater ease and comfort.
Who Needs a Total Knee Replacement?
A total knee replacement may be recommended for patients with severe knee pain and stiffness that significantly affects their quality of life. This may be caused by a variety of factors, including osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, and other degenerative conditions that cause the breakdown of cartilage in the knee joint. Other factors that may warrant a total knee replacement include injury, trauma, or other deformities that affect the knee joint.
A total knee replacement typically takes around two hours to complete and is performed under general or spinal anesthesia. During the procedure, the surgeon will make an incision in the knee area and remove the damaged cartilage and bone from the knee joint. The surgeon will then prepare the surface of the remaining bone to receive the artificial joint components.
The artificial joint is made up of three components: the femoral component, the tibial component, and the patellar component. The femoral component is made of metal and is attached to the end of the thigh bone. The tibial component is made of metal and plastic and is attached to the top of the shin bone. The patellar component is made of plastic and is placed behind the kneecap.
Once the artificial joint is in place, the surgeon will close the incision and apply a bandage or dressing to the knee. Patients are typically required to stay in the hospital for several days after the surgery to monitor their recovery and begin physical therapy.
Recovery and Rehabilitation
Recovery after a total knee replacement can take several weeks or months, and it is essential to follow your surgeon’s instructions carefully to ensure a successful outcome. During the recovery period, patients may experience some discomfort, swelling, and stiffness in the knee joint. Pain medication and physical therapy can help alleviate these symptoms and promote healing.
Physical therapy is a critical component of recovery after a total knee replacement. It helps patients regain strength and flexibility in the knee joint and improve their range of motion. The physical therapist will work with the patient to develop a personalized rehabilitation plan that may include exercises, stretches, and other activities designed to help the patient regain knee function and mobility.
Risks and Complications
As with any surgical procedure, there are risks and complications associated with total knee replacement surgery. These can include infection, blood clots, nerve damage, and implant failure. Patients with pre-existing medical conditions, such as diabetes or heart disease, may be at a higher risk for complications.
It is essential to discuss any concerns you may have with your surgeon before undergoing the procedure. Your surgeon can help you understand the risks and potential benefits of the surgery and develop a plan to minimize the risk of complications.
A total knee replacement can be a highly effective treatment option for patients with severe knee pain and stiffness that affects their quality of life. While the surgery does come with risks, it can help alleviate pain and improve knee function, allowing patients to return to their daily activities with greater.
