Quick Answer
Robotic knee replacement offers greater precision than traditional surgery – placing the implant within 0.5mm of the surgical plan, compared to 1-2mm with manual technique. This improved accuracy can mean less early pain and better long-term implant wear. However, traditional knee replacement remains an excellent operation for most patients. Dr. Pulak Vatsya, a robotic knee replacement surgeon at StepUp Joints, Lajpat Nagar, recommends robotic assistance mainly for younger patients, those with complex anatomy, and high-activity individuals. For straightforward cases, both approaches deliver excellent results.
The Core Difference
The difference between robotic and traditional knee replacement is precision – not whether a machine performs the surgery. In both cases, the surgeon makes every decision and performs the operation. Dr. Pulak Vatsya explains that the robotic system simply provides a 3D map of the patient’s specific knee and guides the bone cuts to sub-millimetre accuracy.
In traditional knee replacement, the surgeon uses mechanical alignment guides and tactile judgement. In robotic knee replacement, a pre-operative CT scan creates a patient-specific plan, and the robotic arm assists Dr. Pulak Vatsya in executing that plan with far greater consistency.

Which One Does Dr. Pulak Vatsya Recommend?
Dr. Pulak Vatsya does not believe every patient needs robotic surgery. At StepUp Joints, Lajpat Nagar, he recommends robotic knee replacement for:
-
Patients under 65 who need the implant to last 20+ years
-
Those with significant deformity or complex bone anatomy
-
Patients who have had previous knee surgery
-
Those considering partial (unicompartmental) knee replacement, where robotic precision is especially valuable
For older patients with straightforward anatomy, Dr. Pulak Vatsya explains that a well-performed traditional knee replacement delivers equally excellent outcomes at lower cost. This honest, patient-specific assessment is part of every consultation at StepUp Joints, South Delhi.
Frequently Asked Questions
Is robotic knee replacement better than traditional?
For the right patient, robotic knee replacement offers superior precision and potentially better implant longevity. But for many patients, traditional knee replacement achieves equivalent results. Dr. Pulak Vatsya assesses each patient individually at StepUp Joints, Lajpat Nagar.
Does robotic knee replacement cost more in Delhi?
Yes, robotic knee replacement typically costs 20-40% more than traditional surgery. Dr. Pulak Vatsya discusses cost and value transparently during consultation at StepUp Joints, Lajpat Nagar, New Delhi.
Where can I get robotic knee replacement in South Delhi?
Dr. Pulak Vatsya performs robotic knee replacement using the VELYS and MAKO platforms at Fortis Escorts Hospital, Okhla, with consultations at StepUp Joints, Lajpat Nagar.
