Knee Replacement

Ending Knee Arthritis Pain with Advanced Total Knee Replacement

Total Knee Replacement (TKR) is a highly effective surgical solution for debilitating knee pain caused by severe osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis. Dr. Ralph Rizk specializes in utilizing Robotic-Assisted Technology (MAKOplasty) to perform your TKR, ensuring the highest level of precision in implant placement and alignment.

The goal of TKR is to remove the damaged bone and cartilage surfaces and replace them with smooth, functional components made of metal and medical-grade plastic, eliminating painful bone-on-bone friction.

The Advantage of Robotic-Assisted TKR

Robotic assistance is not about automation; it is about unmatched customization and accuracy. Before your surgery, a 3D model of your knee is created. During the procedure, Dr. Rizk uses the robotic arm as a highly accurate guidance system:

Precision: The system ensures that bone cuts are made exactly according to the customized pre-operative plan, often within fractions of a millimeter.
Optimal Alignment: Achieving perfect mechanical alignment is crucial for the longevity and natural feel of the new knee joint.
Soft Tissue Balancing: The robotic system assists in ensuring the ligaments are balanced, which is vital for the stability and function of the knee.

When To Consider Total Knee Replacement?

Total knee replacement is typically recommended when:

Knee pain is constant and significantly interferes with daily life (walking, climbing stairs).
Pain persists even during rest or at night.
The knee joint shows advanced cartilage deterioration (bone-on-bone) on X-rays.
Conservative treatments, such as injections, therapy, and medications, have failed to provide lasting relief.

The Recovery Process

Recovery after TKR requires commitment to physical therapy. While the robotic and modern surgical techniques promote earlier mobilization, adherence to the rehabilitation protocol is key to maximizing your outcome. Most patients achieve significant functional improvement in just a few months.

Why Trust Dr. Rizk with Your Orthopedic Muscle, Bone and Joint Health?

Finding the right orthopedic specialist is the most critical step toward a successful recovery. With Dr. Rizk, you are entrusting your care to a board-certified, fellowship-trained orthopedic surgeon whose dedication is not just to surgical excellence—it's to personalized care.

His approach always begins with exploring conservative, non-surgical treatment options first. He leverages the latest, most advanced techniques in orthopedic care, reconstruction, and sports medicine to ensure your treatment plan is tailored precisely to your injury, activity level, and recovery goals. Whether you're an athlete looking to get back in the game or someone who wants to walk comfortably around the neighborhood, Dr. Rizk is committed to restoring your mobility and quality of life. His practice is deeply rooted in serving the Northeast Florida community, including Jacksonville, Cove Springs and surrounding areas.

Your Knee Replacement Questions, Answered.

Thanks to advanced techniques and pain management protocols, many patients now go home after just one night in the hospital. Some may even be candidates for same-day discharge.
Most patients will walk with assistance (walker or crutches) shortly after surgery. The timeline for walking unassisted varies greatly, but many reduce their reliance on aids within 2 to 4 weeks, with the goal of walking normally within 6 to 8 weeks.
Yes, while your pain is gone, you should avoid high-impact activities like running, jogging, and jumping to protect the implant. Activities like walking, swimming, cycling, and golf are strongly encouraged.
