Understanding the Distinction Between Robotic and Conventional Knee Replacement



For people suffering from severe knee pain because of multiple conditions, including osteoarthritis or accident, knee replacement procedures or tkr surgery are becoming increasingly popular. With the emergence of robotic-assisted knee replacements, orthopaedic surgery has significantly advanced in recent years. Even though conventional knee replacement methods have been used effectively for many years, robotic technology has emerged as a game-changing procedure that delivers more accuracy and better results.

What is Conventional Knee Replacement Surgery?

The conventional knee replacement technique, sometimes called total knee arthroplasty, is a well-known procedure carried out by orthopaedic surgeons. It entails removing the knee joint's worn-out bone and cartilage and replacing it with a prosthetic joint of metal and plastic parts. Numerous people have significantly benefited from this operation and seen improved quality of life.

Conventional knee replacement surgery or tkr surgery does have certain drawbacks, though. The surgeon's ability and experience are crucial to precisely align the parts and balance the ligaments within the knee. The accuracy of the process can be impacted by variations in surgical procedures and human error, which can occasionally result in less-than-ideal results. Additionally, healing and rehabilitation following surgery can be difficult and time-consuming.

What is Robotic-Assisted Knee Replacement Surgery?

An important advancement in orthopaedics is robotic-assisted knee replacement surgery. This ground-breaking method improves surgical precision and patient care by fusing the surgeon's skill with robotic technology's capabilities.

An innovative piece of software directs the robotic arm that is used by surgeons during a robotics knee replacement. The patient's knee is scanned before surgery to produce a 3D model that aids in pre-operative planning. The surgeon utilises the robotic arm to get rid of damaged tissue and precisely place the prosthetic parts during the procedure.

The use of robotics offers several advantages over conventional techniques. Firstly, the robotic system provides the surgeon with real-time feedback, enabling precise alignment of the prosthetic components based on the patient's unique anatomy. This accurate positioning helps optimise the functioning of the knee joint and can contribute to improved long-term outcomes.

Additionally, robotic technology allows for meticulous ligament balancing, critical for achieving natural knee movement and stability. The system provides comprehensive data on the patient's joint mechanics, enabling the surgeon to adjust and fine-tune the procedure.

In addition, minimally invasive knee replacement surgery is possible with robotic assistance. The great degree of control of the robotic arm enables fewer incisions, less soft tissue stress, and less blood loss. This may result in shorter hospital stays, quicker recovery times, and less post-operative discomfort than conventional methods.

What Are the Benefits of Conventional & Robotic Knee Replacement Surgery?

To better understand the distinction between robotic and conventional knee replacement, let's summarise the key benefits of each approach:

Conventional Knee Replacement:

  • Established track record with long-term success.
  • Widely available and performed by experienced surgeons.
  • Suitable for a broad range of patients.

Robotic-Assisted Knee Replacement:

  • Unparalleled precision in implant positioning and alignment.
  • Improved ligament balancing for natural knee movement.
  • Personalised surgical planning based on individual anatomy.
  • Minimally invasive with smaller incisions and reduced trauma.
  • Enhanced post-operative recovery and shorter hospital stays.

However, the choice between robotic-assisted and conventional knee replacement ultimately depends on various factors, including the patient's specific condition, surgeon expertise, and availability of resources. A thorough discussion with a qualified orthopaedic surgeon is crucial in determining the most suitable approach for each case.

What Are the Potential Limitations of Robotic-Assisted Knee Replacement Surgery?

While robotic-assisted knee replacement surgery offers numerous advantages, it is important to know the potential limitations and factors to keep in mind:


Robotics knee replacement surgery may be more expensive than conventional procedures due to the additional technology and resources required. Hence, you should first enquire the knee replacement surgery cost with multiple hospitals. However, the long-term benefits and improved outcomes can outweigh the initial costs for some patients.

Learning Curve:

Surgeons adopting robotic technology may require additional training and experience to perform robotic-assisted knee replacements. It is crucial to select a surgeon having specialised training and a proven track record in robotic systems.


Robotic-assisted knee replacement may not be readily available in all healthcare facilities. Access to robotic systems can vary depending on geographical location and healthcare infrastructure. However, platforms like MediBuddy can help individuals find surgeons and facilities that offer robotic-assisted procedures.

Individual Suitability:

Not all patients may be suitable candidates for robotic-assisted knee replacement. Various factors such as patient anatomy, the severity of the disease, and overall health must be carefully evaluated by the surgeon to determine the most appropriate approach.

Surgeon Expertise:

While robotic technology provides precise assistance, the surgeon's skill and experience still play a crucial role in the procedure's success. Choosing a highly experienced surgeon with a deep understanding of knee anatomy and robotic-assisted techniques is vital.

What Future Directions and Innovations Can be Seen for Robotic-Assisted Knee Replacement Surgery?

The field of robotic-assisted knee replacement surgery continues to evolve, with ongoing advancements and innovations such as:

Enhanced Imaging Techniques:

Advancements in imaging technology, such as 3D printing and augmented reality, are revolutionising pre-operative planning. These techniques provide detailed patient-specific models and simulations, allowing surgeons to tailor surgical strategies and optimise outcomes.

Implant Customisation:

The ability to create patient-specific implants using 3D printing technology holds promise for optimising fit and functionality. Customised implants can better mimic the natural knee joint, potentially leading to an improved range of motion and longevity of the implant.

Virtual Reality Training:

Virtual reality platforms are being developed to enhance surgeon training for robotic-assisted knee replacement surgery. These simulations provide a realistic surgical environment, allowing surgeons to practice and refine their skills in a safe and controlled setting.


Robotic-assisted knee replacement surgery is a critical improvement in orthopaedic therapy, which provides unmatched accuracy and better patient results. Although traditional knee replacement methods have been successful, robotic technology offers more precision, customisation, and minimally invasive procedures. However, some factors like knee replacement surgery cost, recovery time, and health damages must be considered before selecting the type of procedure. Access to robotic-assisted knee replacements is increasing because websites like MediBuddy pair patients with skilled orthopaedic surgeons. This empowers people to make educated healthcare decisions and enhances their quality of life.
