Total knee replacement (TKR) is a widely recognized surgical procedure aimed at relieving pain and restoring function in severely diseased knee joints. This procedure is especially effective for those suffering from advanced osteoarthritis, rheumatoid arthritis, or traumatic knee injuries. Understanding the intricacies of TKR can help patients make informed decisions and ensure a smoother recovery process.
What is Total Knee Replacement?
Total knee replacement, also known as knee arthroplasty, involves replacing the damaged surfaces of the knee joint with artificial components made of metal alloys, high-grade plastics, and polymers. The goal is to mimic the movement of a healthy knee, allowing for a pain-free, functional joint.
Who Needs Total Knee Replacement?
This surgery is often recommended for individuals who experience severe knee pain or stiffness that limits everyday activities, such as walking, climbing stairs, or even sitting and rising from a chair. Candidates typically have tried nonsurgical treatments like medications, physical therapy, and injections without relief.
The Surgical Procedure*
During the procedure, the surgeon makes an incision in the knee to access the joint. Damaged cartilage and bone are carefully removed, and the new artificial components are positioned to restore alignment and function. The surgery typically takes about one to two hours, and patients are usually required to stay in the hospital for a few days.
Recovery and Rehabilitation
Post-surgery, patients can expect some pain and discomfort, which can be managed with medications. Physical therapy is crucial during the recovery process, helping to restore movement and strength in the knee. Most patients can resume normal activities within three to six weeks, although complete recovery may take several months.
Risks and Complications
As with any major surgery, TKR carries risks, including infection, blood clots, and implant loosening or wear over time. However, the overall success rate of knee replacement surgery is high, with most patients experiencing significant pain relief and improved function.
Longevity of Knee Implants
Modern knee implants are designed to last for 15-20 years or more. Factors that influence the longevity of the implant include the patient’s activity level, weight, and adherence to post-operative care instructions.
Total knee replacement is a highly effective surgical solution for those suffering from debilitating knee pain. With proper care and rehabilitation, most patients can enjoy a dramatic improvement in their quality of life. Contact Great Lakes Orthopaedics to learn more about total knee replacement options.
