What is Robotic Partial Knee Replacement (Unicondylar)?

DR. CHETAN WANKHEDE is Consultant Orthopaedic Surgeon and Robotic Partial Knee Replacement Surgeon in Thane and Mumbai.

Robotic partial knee replacement, also known as unicondylar knee replacement, is an advanced minimally invasive procedure in which only the damaged portion of the knee joint is replaced using robotic-assisted technology. This technique allows for highly precise implant placement while preserving healthy bone, cartilage, and ligaments, resulting in a more natural-feeling knee.

Who is a candidate for Robotic Partial Knee Replacement?

This procedure is suitable for patients whose arthritis is limited to a single compartment of the knee, commonly the medial (inner) side. Ideal candidates have good ligament function, minimal deformity, and relatively healthy remaining knee structures. It is recommended when non-surgical treatments like medications and physiotherapy do not provide adequate relief.

How is Robotic Partial Knee Replacement different from traditional surgery?

Robotic-assisted surgery uses advanced imaging and computer navigation to create a personalized surgical plan for each patient. The robotic system helps the surgeon perform precise bone preparation and accurate implant positioning. Compared to traditional methods, it offers improved accuracy, better joint alignment, and preservation of healthy tissues.

What are the advantages of Robotic Partial Knee Replacement?

Robotic partial knee replacement offers several benefits:

• Minimally invasive procedure with smaller incision
• Preservation of healthy bone and ligaments
• More natural knee movement and function
• Less pain and reduced blood loss
• Faster recovery and early return to daily activities
• Shorter hospital stay, often same-day discharge
• Improved implant accuracy and longevity

What is the recovery process after Robotic Partial Knee Replacement?

Recovery after robotic partial knee replacement is usually quicker compared to total knee replacement. Patients are often able to walk on the same day or within 24 hours after surgery. With proper physiotherapy and rehabilitation, most patients return to normal activities within a few weeks.

What advice do you have for a speedy recovery?

For a smooth recovery, patients should follow a structured physiotherapy program, stay active, and maintain a healthy lifestyle. Prehabilitation before surgery can strengthen muscles and improve outcomes. Following the surgeon’s guidance and attending regular follow-ups ensures long-term success and better joint function.
