Knee Replacement surgery has helped millions of people regain mobility, overcome chronic pain, and return to a fuller, more active life. Yet, despite its success, misconceptions continue to worry patients and delay timely treatment. In today’s era of advanced and latest technology, especially with the introduction of robotic technology in orthopaedic care, it is essential to separate fact from fiction.

At NHS Ortho Robotics (a unit of NHS Hospital), Dr Shubhang Aggarwal, Senior Orthopaedic Surgeon with 22+ years of experience, along with a 5 Orthopaedic surgeons team, has been at the forefront of bringing safe, precise and minimally invasive solutions to patients. As one of the firsts in the region to adopt cutting-edge robotic technique, the centre is committed to delivering accuracy and faster recovery through innovation.

Let’s explore the most common myths surrounding knee replacement and uncover the real facts every patient should know.

Myth 1: “Knee Replacement Is Only for the Elderly.”

Fact: Age is not the deciding factor — quality of life is.

Many people believe knee replacement is meant only for senior citizens. However, the decision depends on the severity of joint damage and its impact on daily activities, not on age alone. Younger patients with severe arthritis, injuries, or deformities may also benefit from surgery.

Modern robotic technology ensures precise alignment and customised implant positioning regardless of the patient’s age, making the surgery safer and more predictable for all age groups.

Myth 2: “Knee Replacement Is Very Painful and the Recovery Is Long.”

Fact: With the robotic technique, recovery is significantly faster and more comfortable.

Pain has always been a concern for patients, but advancements in surgical methods have changed the entire experience.

With robotic-assisted knee replacement, surgeons are able to create a highly accurate 3D plan of the patient’s knee before surgery. Robotic precision reduces tissue damage, ensures a smoother procedure, and supports quicker rehabilitation. Many patients begin walking within 24 hours and resume daily routine activities earlier than expected.

Myth 3: “Robotic Knee Replacement Is Risky.”

Fact: Robotic-assisted surgery enhances safety and precision.

The robot never performs the surgery on its own. Instead, it works as a guiding tool controlled fully by the orthopaedic surgeon.

At NHS Ortho Robotics, robotic systems assist the surgeon by mapping the knee joint in real time, allowing sub-millimetre accuracy.

Myth 4: “Knee Replacement Implants Don’t Last Long.”

Fact: Modern implants can last 25–30 years or more with proper care.

Robotic precision improves implant longevity by ensuring perfect alignment and load distribution, minimising wear and tear.

Myth 5: “Walking and Daily Activities Will Be Restricted After Surgery.”

Fact: Most patients regain full mobility — and often more than before.

After recovery, patients can comfortably walk, climb stairs, cycle, and carry out their routine activities.

Technology Doesn’t Make a Big Difference.

Fact: Robotic technique enhances accuracy, safety, and outcomes.

Robotic platforms offer personalised mapping, precise bone cuts, and an ideal ligament balance tailored to each patient’s unique structure.

Conclusion: Knowledge Empowers Better Decisions

Knee replacement is a life-changing procedure, but the right information is essential. With modern innovations like the robotic technique, patients now have access to safer, more accurate, and faster-recovery options.

Backed by Dr Shubhang Aggarwal’s 22+ years of experience and a highly dedicated 5 Orthopaedic surgeons team, NHS Ortho Robotics continues to lead the way in cutting-edge orthopaedic care.
