Knee replacement has always been associated with pain and prolonged treatment, especially when senior citizens are involved. Now, minimally-invasive surgery without pain and physiotherapy is possible.

“Computer-assisted knee replacement and segmental knee replacement for early treatment of knee arthritis is here to stay,” said M. Madhanmohan Reddy, senior consultant knee surgeon with Apollo Hospitals, Chennai, at a media conference here on Thursday.

Knee replacement is generally done for patients in the 60-years age group with end-stage osteoarthritis, but the same is necessary even for relatively young patients with severe rheumatoid arthritis. “Patients with severely deformed joints and are unable to carry out their activities also require this,” he explained.

After basic physiotherapy on the same day, the patient would be discharged on the fourth day of surgery, while sutures could be removed on the tenth day. The implants would also last for 25-30 years, Dr. Reddy added.
