Treatments

Care for the joints that carry you

Most patients arrive after months of pain and conflicting advice. Each page below explains what the condition is, when surgery is genuinely warranted, and what recovery actually looks like week by week.

First in Kolkata

Robotic knee replacement

Robot-assisted partial and total knee replacement, planned to sub-millimetre accuracy. More of your healthy knee is preserved, and most patients are walking the same day.

How robotic surgery works →

Knee replacement

Total, partial and revision knee replacement for advanced arthritis, including high-flex implants for patients who need to squat and sit cross-legged.

Hip & joint replacement

Total and revision hip replacement, complex arthroplasty, and shoulder joint replacement — including for avascular necrosis in younger patients.

Read more →

Arthroscopy

Keyhole surgery of the knee and shoulder for meniscus tears, cartilage damage and rotator cuff injuries, through incisions a few millimetres wide.

Read more →

Sports injury & ACL

ACL and ligament reconstruction, meniscus repair and return-to-sport rehabilitation for athletes and active adults.

Read more →

Robotic surgery

Kolkata’s first robotic partial knee replacement

In a partial knee replacement, only the damaged compartment of the knee is resurfaced and the healthy ligaments and bone are left intact. Doing that accurately is difficult by hand. The VELYS robotic system plans the cut to within a fraction of a millimetre and holds the surgeon to that plan.

  • A more natural-feeling knee, because healthy structures are preserved
  • No routine activity restrictions — cross-legged sitting and squatting are permitted
  • A minimally invasive approach and a quicker return to daily life
  • Improved implant longevity when alignment is accurate

Supporting Seniors, Transforming Lives

January 2025 Marriott, New Town, Kolkata

Dr. Karmakar spoke at this public awareness initiative on healthy ageing, presented by Manipal Hospitals in association with The Times of India. The session addressed how bone and joint problems progress in older adults, which symptoms should not be dismissed as ordinary age-related aches, and when joint replacement becomes worth considering.

A recurring question from the audience: how long a replaced joint lasts, and whether an older patient is ever “too old” for surgery. The answer, in most cases, is that general health matters far more than age.
