Comparing normal and Robotic TKR

1. Precision and Accuracy:

One of the primary drawbacks of conventional TKR is the reliance on manual techniques, which may lead to variations in precision and accuracy. Robotic TKR, on the other hand, offers a higher degree of precision due to real-time imaging and computer-guided assistance, potentially resulting in better alignment and implant positioning.

2. Individualized Anatomy Mapping:

Conventional TKR relies on pre-operative planning and the surgeon’s experience to navigate the patient’s unique anatomy. Robotic TKR utilizes advanced imaging technology to create a personalized 3D map of the joint, allowing for a more tailored and precise approach.

3. Limited Intraoperative Feedback:

In conventional TKR, surgeons have limited real-time feedback during the procedure. This lack of immediate guidance may lead to challenges in adjusting the surgical plan as needed. Robotic-assisted surgery provides continuous feedback, enabling surgeons to make real-time adjustments for optimal outcomes.

4. Potential for Human Error:

Manual techniques in conventional TKR may be susceptible to human error, leading to suboptimal implant alignment and positioning. Robotic systems can reduce the likelihood of human error by providing enhanced guidance and ensuring that the surgical plan is executed with a high level of accuracy.

5. Longer Recovery Times:

Conventional TKR surgeries, particularly those involving larger incisions, may result in longer recovery times compared to minimally invasive robotic procedures. Robotic-assisted surgeries often involve smaller incisions, leading to reduced trauma, faster healing, and quicker rehabilitation for patients.

6. Limited Standardization of Techniques:

Conventional TKR techniques can vary among surgeons, as they rely on individual skills and experience. Robotic-assisted surgery offers a higher level of standardization, potentially reducing variability in outcomes across different surgeons and healthcare facilities.

7. Revision Rates:

Studies suggest that conventional TKR may have slightly higher revision rates compared to robotic-assisted TKR. The improved precision and alignment achieved with robotic systems contribute to the longevity of the implant, potentially reducing the need for revisions.


While conventional TKR remains a widely practiced and effective procedure, the emergence of robotic-assisted TKR addresses some of its limitations, offering enhanced precision, individualized planning, and potential improvements in patient outcomes. However, it’s crucial to note that the choice between conventional and robotic TKR depends on various factors, including surgeon expertise, patient characteristics, and available technology.
