In an effort to make total knee replacement surgery more patient-friendly, Indraprastha Apollo Hospital has brought in patient-specific instruments, which it claims will be a boon for patients suffering from arthritis.

No pain

“The technique improves alignment and sizing of the joint by using computer-generated images of the patient’s anatomy to determine precise bone cuts, and implant positioning during the surgery. The advanced nature of the technique enables lesser surgery time, lesser bleeding, lesser post-operative complications and lesser dissection allowing quick post-operative recovery,” said the Hospital’s senior consultant joint replacement surgeon Dr. (Prof) Raju Vaishya.

Using this patient-specific instruments (PSI) in total knee replacement, doctors at the Hospital recently helped Surinder Rawat, a 68-years-old woman from Gurgaon, who was suffering from a severe case of rheumatoid arthritis regain her mobility without experiencing any pain.

On May 20, a team of doctors conducted a total knee replacement surgery on Ms. Rawat for both her knees using PSI for total knee arthroplasty.

The surgery of both the knees was successfully performed under spinal/epidural anaesthesia and took less than one and a half hours to finish. Ms. Rawat was discharged within five days of the surgery in a walking condition.

Benefits galore

Commenting on the benefits of the technique of patient-specific instruments in total knee replacement, Dr. Vaishya said: “This technique improves alignment and sizing by using computer-generated images of the patient’s anatomy to determine precise bone cuts, and implant positioning during the surgery. It also eliminates the need to violate the intra-medullary canal, thereby reducing blood loss during and after surgery and serious complications like fat emboli. As many operative steps are reduced in this technique, and excessive dissection is not required, the operative time for the knee replacement procedure is reduced by half.”
