Your double-fellowship-Trained Ankle Replacement Specialist
Robotic Ankle Replacement Surgery in Buffalo, NY
Living with severe ankle arthritis can feel like a losing battle. Each step brings pain, stiffness limits your movement, and the activities you once enjoyed seem increasingly out of reach. When conservative treatments like bracing and injections no longer provide relief, many patients fear their only option is an ankle fusion, which eliminates motion entirely. However, there is another path. Ankle replacement surgery is an advanced procedure that relieves pain while preserving the motion of your joint. But this complex surgery requires a highly specialized skillset, and finding the right surgeon is critical.
At Buffalo Orthopedics, Dr. Parentis is one of only a select few surgeons in the area performing ankle replacement surgery and using robotic-assisted technology to augment his process. With over 25 years of experience and double fellowship training in both sports medicine and foot/ankle surgery, he brings a level of expertise that is hard to find. Unlike large hospital systems where you might feel like just another number, our practice offers a familiar atmosphere where everybody knows your name. You will be seen directly by Dr. Parentis on many occasions, ensuring your care is managed by an expert at every step. We are currently accepting new patients and welcome those seeking second opinions or handling Workers' Compensation cases.

What is Robotic Ankle Replacement Surgery and How Does it Work?
Ankle replacement surgery, also known as total ankle arthroplasty, is a procedure designed to replace a damaged ankle joint with an artificial implant. Much like knee or hip replacement, the goal is to eliminate the source of pain—usually worn-out cartilage and bone-on-bone friction—while maintaining the joint's natural movement. This is a sophisticated alternative to ankle fusion, which locks the joint in place.
During the procedure, Dr. Parentis removes the damaged bone and cartilage surfaces from the tibia (shin bone) and the talus (the foot bone that articulates with the leg). These are replaced with metal components. A high-quality plastic spacer is then inserted between the metal parts to create a smooth gliding surface, mimicking the natural motion of a healthy ankle. Because Dr. Parentis is one of the few ankle replacement doctors in the region with the specific training to perform this surgery, he utilizes the most advanced robotic assistance, implants, and techniques available. This precision helps restore your gait and allows you to walk more naturally than you would with a fused ankle.

Frequently Asked Questions About Ankle Replacement
What Does Ankle Replacement Surgery Treat or Help With?
The primary condition treated by ankle replacement surgery is end-stage ankle arthritis. This debilitating condition can result from osteoarthritis (wear and tear over time), rheumatoid arthritis (an inflammatory disease), or, most commonly, post-traumatic arthritis (arthritis that develops years after a severe fracture or injury). When the smooth cartilage that cushions the joint wears away, the bones rub against each other, causing severe pain, inflammation, and stiffness.
This surgery helps by removing the painful, damaged surfaces and replacing them with a prosthetic joint. The benefits are significant:
- Pain Relief: The primary goal is to drastically reduce or eliminate the deep, aching pain of arthritis.
- Preserved Motion: Unlike fusion, replacement allows you to keep moving your ankle up and down, which facilitates a more normal walking pattern.
- Protection of Other Joints: By preserving ankle motion, less stress is placed on the surrounding joints of the foot and knee, potentially preventing arthritis in those areas.
If you are suffering from chronic ankle pain that limits your daily life, consulting an orthopedic doctor in Orchard Park, NY like Dr. Parentis can help you determine if this procedure can restore your mobility.
What Happens During an Ankle Replacement Appointment?
Your experience at Buffalo Orthopedics is defined by personal connection. Your first appointment will likely consist of a dedicated consultation with Dr. Parentis himself. He prides himself on being an accessible ankle orthopedic doctor who builds real relationships with his patients. He will start by listening to your story—how your ankle pain affects your work, your hobbies, and your ability to walk. He will review your medical history and any previous treatments you have tried.
Next, Dr. Parentis will perform a thorough physical examination to assess the alignment, stability, and range of motion of your ankle. He will likely review X-rays, and possibly a CT scan or MRI, to evaluate the extent of the arthritis and the quality of your bone stock. This detailed assessment is crucial for planning the surgery. He will then explain the ankle replacement surgery procedure in clear terms, discuss whether you are a good candidate, and answer any questions you have, including inquiries about ankle replacement surgery cost and insurance coverage. This one-on-one time ensures you feel confident and informed about your treatment plan.
Is Ankle Replacement Surgery Safe?
Ankle replacement surgery has evolved significantly over the years and is now considered a safe and effective option for many patients, particularly when performed by a specialized surgeon. Dr. Parentis is one of the few providers in the area with the specific expertise required for this complex procedure. His double fellowship training ensures he has a deep understanding of the intricate biomechanics of the foot and ankle, which helps minimize risks.
As with any major surgery, there are potential risks, including infection, wound healing issues, nerve injury, or the possibility that the implant could loosen over time. However, modern implants and improved surgical techniques have greatly reduced these complications. Dr. Parentis will have a frank and open discussion with you about these risks during your consultation. He is committed to patient safety and will only recommend surgery if the potential benefits for your quality of life outweigh the risks. His hands-on approach means he closely monitors your recovery to address any concerns immediately.
How is Ankle Replacement Different from Other Treatment Options?
The main alternative to ankle replacement surgery for severe arthritis is ankle fusion (arthrodesis). In a fusion procedure, the bones of the ankle are permanently joined together using screws and plates. While fusion is very effective at relieving pain, it comes at a cost: the complete loss of up-and-down motion in the ankle joint. This changes the way you walk and can increase stress on the adjacent joints in the foot and knee, potentially leading to arthritis in those areas later in life.
Ankle replacement is different because it preserves motion. By using an artificial joint, ankle replacement allows patients to maintain a more natural gait. This is often preferred by patients who want to stay active and avoid the stiff-legged walk associated with fusion. Furthermore, compared to non-surgical options like bracing or medications, replacement offers a long-term solution to the mechanical problem of arthritis rather than just managing symptoms. As an ankle replacement specialist near you, Dr. Parentis can help you weigh the pros and cons of replacement versus fusion based on your specific age, activity level, and bone quality.
How Long Does Recovery Take After Ankle Replacement?
Recovery from ankle replacement surgery is a process that requires patience and commitment, but the results can be life-changing. Immediately following surgery, your ankle will be immobilized in a splint or cast to allow the incision to heal and the implant to settle into the bone. You will need to use crutches, a knee scooter, or a walker to keep weight off the ankle for several weeks.
Dr. Parentis will guide you through a specific rehabilitation protocol. Typically, around 2 to 4 weeks post-surgery, you may transition to a removable boot. Physical therapy usually begins once the incision is healed, focusing on gentle range-of-motion exercises to prevent stiffness. Weight-bearing is introduced gradually. Most patients can return to normal daily activities and walking in regular shoes within 3 to 4 months. While high-impact sports like running are generally not recommended after replacement to prolong the life of the implant, low-impact activities like cycling, swimming, and golf are strongly encouraged.
