Lucknow: Doctors at KGMU’s department of orthopaedics successfully performed a partial knee replacement using the microplasty technique—a significant shift from traditional total knee replacements. The microplasty targets only the damaged portion of the knee, preserving healthy tissue and bone. Based on modern computer navigation, it allows for precise alignment and faster recovery with minimal cuts and reduced blood loss.The surgery was conducted by senior orthopaedic surgeon Prof Shailendra Singh on a 52-year-old woman from Sultanpur earlier this week. The patient was operated on under the Ayushman scheme of the govt.Prof Shailendra Singh said, “This is the future of knee surgery. Instead of replacing the entire joint, we now fix only the damaged part. Recovery is faster, pain is less, and the results are long-lasting.” It will cost around Rs 80,000-Rs 90,000.He added that patients can often begin walking within 24 to 48 hours after surgery. “For carefully selected individuals, implants may last over 15 years, with many returning to regular physical activity or sports in a short time,” he said.This technique is especially suited for individuals with localised medial compartment osteoarthritis, intact ligaments and stable joints—typically those who remain active even beyond the age of 40.The surgery involved a small incision of around 6-8 cm, guided instrumentation for accurate placement and the use of the Oxford Knee implant—a proven device developed by Oxford University in partnership with Zimmer Biomet. The implant’s hallmark is a mobile bearing design that mimics natural knee movement and allows most patients to begin walking within 24 to 48 hours.HoD orthopaedics department Prof Ashish Kumar said: “KGMU plans to expand the use of microplasty as a preferred treatment option in early-stage osteoarthritis, particularly among younger, active individuals. The university is also preparing to organise workshops and clinical sessions to train surgeons in this advancing technique.”The surgery team included anaesthesiologists Prof Vineeta Singh and Prof Manoj Chaurasia, as well as orthopaedic colleagues Prof Ravindra Mohan, Dr Deepak Chawda and Dr Ankur Maan.
