JOINT REPLACEMENT
Total Knee Replacement (TKR)
Total Knee Replacement, or TKR, is a surgical procedure designed to alleviate chronic knee pain and restore mobility in individuals with advanced arthritis or significant knee joint damage. By replacing damaged cartilage and bone with artificial components made of durable materials like metal alloys and high-density plastics, TKR aims to recreate the natural function of the knee joint. This procedure is considered when conservative treatments such as medications and physical therapy no longer provide adequate relief. TKR can dramatically improve quality of life by reducing pain, improving mobility, and allowing individuals to participate more fully in daily activities and recreational pursuits.
Preparing for Total Knee Replacement
Preparing for TKR involves thorough pre-operative assessments to evaluate overall health and readiness for surgery. Patients undergo medical tests to assess cardiovascular health, blood clotting risk, and overall fitness for anesthesia. Pre-operative physical therapy may be recommended to strengthen muscles around the knee and optimize joint function. Additionally, patients receive counseling on post-operative care, including pain management strategies and rehabilitation exercises to facilitate a smoother recovery process. Making necessary home modifications and arranging for support from family or caregivers are also essential steps in preparing for TKR.
Surgery Overview
TKR surgery is performed under general anesthesia, typically lasting between 1 to 3 hours. During the procedure, the orthopedic surgeon makes an incision over the knee joint to access the damaged surfaces. The damaged cartilage and bone are then removed, and precise measurements are taken to ensure proper alignment of the artificial components. These components, including a metal alloy implant for the femur and tibia, and a high-density plastic spacer, are securely fixed to recreate smooth joint movement. The incision is closed with sutures or staples, and a sterile dressing is applied to promote healing.
Life After Total Knee Replacement
After TKR, patients begin a comprehensive rehabilitation program to restore knee function and strength. Physical therapy sessions focus on improving range of motion, building muscle strength, and enhancing overall joint stability. Initially, patients may use assistive devices such as crutches or walkers to support mobility. Most individuals experience significant pain relief and improved joint function within weeks to months after surgery. As healing progresses, patients typically regain the ability to perform daily activities such as walking, climbing stairs, and participating in recreational activities with greater comfort and ease.
Role of Total Knee Replacement
TKR plays a pivotal role in enhancing quality of life for individuals suffering from severe knee arthritis or joint damage. By alleviating pain, restoring mobility, and improving joint function, TKR enables patients to lead more active and independent lives. It reduces dependence on pain medications and enhances overall well-being, allowing individuals to participate in social, occupational, and recreational activities with renewed confidence and comfort. TKR is a proven and effective treatment option that has helped millions of people worldwide regain mobility and improve their overall quality of life.
