A precise, less invasive approach that resurfaces only the damaged part of your knee, helping you recover faster and get back to the activities you love.
Partial knee replacement (UKR), at a glance.
A quick summary of what the procedure involves, who it's for, and what to expect — from recovery to cost.
Partial knee replacement (UKR) is a precision, image-guided procedure that resurfaces only the damaged compartment of the knee using Dr. Unmesh Chakraverty's MISSO robotic system, while preserving healthy bone and ligaments. Recommended for patients with early to moderate arthritis limited to one part of the knee. Recovery to daily activities typically takes 3 to 6 weeks. Total cost varies by implant and hospital stay, confirmed during consultation.
ABOUT THE TREATMENT
A Smarter Approach to Partial Knee Replacement
Partial knee replacement (UKR) is a less invasive form of knee surgery that resurfaces only the damaged compartment, leaving healthy bone, cartilage and ligaments untouched. A personalised surgical plan is created from your own anatomy, then the MISSO robotic arm helps Dr. Unmesh position the implant with sub-millimetre precision. The result is a faster recovery, a more natural-feeling knee, and a shorter hospital stay.

BENEFITS
Benefits of Partial
Knee Replacement (UKR)
A less invasive path to a pain-free knee. Robotic precision helps preserve what's healthy, so recovery is faster and more natural.
01
Bone & Ligament

Right for You?
Not every case of knee arthritis needs a full replacement. If your pain is limited to one part of the knee, partial replacement may be a suitable, less invasive option.

FREQUENTLY ASKED QUESTIONS
Your Questions, Answered
What is partial knee replacement (UKR)?
Partial knee replacement resurfaces only the damaged compartment of the knee, leaving healthy bone and ligaments untouched. It is a less invasive alternative to total knee replacement, guided by precise 3D imaging and robotic assistance for accurate implant positioning.
How is UKR different from total knee replacement?
Partial knee replacement treats only the damaged part of the knee, while total knee replacement resurfaces the entire joint. UKR typically involves a smaller incision, less bone removal, and a faster recovery, but is only suitable when arthritis is limited to one compartment.
How long does UKR surgery take?
Robotic-assisted partial knee replacement typically takes 45 to 75 minutes, often less time than a total knee replacement. The exact duration depends on your knee's condition, and robotic guidance helps keep the procedure precise and efficient throughout.
When can I walk after surgery?
Most patients stand and walk with assistance on the same day or within 24 hours of surgery. Because less tissue is disturbed than in a total knee replacement, many patients regain mobility and confidence more quickly.
How long is the recovery period?
Most patients return to daily activities within 3 to 6 weeks, faster than typical total knee replacement recovery. Strength, flexibility and confidence continue to improve over the following weeks, with many patients back to normal routines by 3 months.
Is robotic partial knee replacement safe?
Yes, robotic-assisted partial knee replacement is a well-established and safe procedure. The MISSO system acts as a precision guide controlled entirely by your surgeon, helping protect healthy bone and ligaments while improving implant accuracy.
Am I a candidate for partial knee replacement?
Suitability depends on where your arthritis is located and how healthy your ligaments are. Partial knee replacement generally suits patients with early to moderate arthritis confined to one compartment, and Dr. Unmesh will confirm candidacy through examination and imaging.
How long is the hospital stay?
Most patients stay in hospital for 1 to 3 days after surgery, often shorter than a total knee replacement stay. The exact length depends on your recovery progress and individual health factors, and our team guides you through discharge planning.
How long does the implant last?
Modern partial knee implants placed with robotic precision typically last 15 to 20 years or more with proper care. Accurate alignment helps distribute joint load evenly, reducing wear and helping your implant perform reliably over the long term.
Can I have a total knee replacement later if needed?
Yes, if arthritis progresses in other parts of the knee, a total knee replacement can usually still be performed later. Dr. Unmesh will monitor your knee over time and discuss options should further treatment ever be needed.
