Computer-Assisted Knee Replacement Surgery

Avatar Health, Top Stories

According to Dr Maichand (Ashwani Maichand), When your knee doesn’t respond to medications and treatments, knee replacement surgery is the last option.

The advancements in medical technology have led to precise and highly functional artificial knee implants that nearly duplicate the way the human knee moves—and are custom fit for your body. It is now among the safest and most effective of all standard orthopedic surgeries.

There are two types of replacement surgeries: total knee replacement and partial knee replacement. Total knee replacement comprises more than 90 per cent of today’s procedures.

Benefits of Computer-assisted Surgery

Computers can take the “guess work” out of surgery. It allows the surgery to be done with greater precision and accuracy.

Why is it important in knee replacement?

Many studies have shown that knee replacements that are performed well (for example, well-aligned and balanced) are likely to last longer and feel better. In addition, it can shorten the hospital stay and decreases recovery time. Computer-assisted surgery can help the surgeon align the patient’s bone and implants with a degree of accuracy not possible with

the naked eye. It can also help in ligament balancing that can ensure better range of motion and a more

natural functioning knee replacement.

What are other benefits of computer-assisted surgery?

Computer-assisted surgery increases the precision and accuracy, and gives the surgeon real-time feedback during the surgery. This procedure also decreases errors by alerting the surgeon to potential pitfalls before they are performed. It gives the surgeon the confidence to perform the surgery with precision and control.

Potential Complications: Computer -assisted total knee replacement is very safe. This is because surgeons who use computer-assisted surgery utilize instruments that do not disturb the marrow. It is believed to be safer than traditional surgery. Moreover, it leads to less blood loss and may lead to the decrease in blood transfusion requirement after the surgery.

Are all surgeons trained in computer-assisted surgery?

Like all other complex technology, not all individuals are trained in computer-assisted surgery. It is more


Does it take additional time to perform?

Like any technology, there is a learning curve for both the surgeon and the OR staff. In hospitals where surgeons and OR staff embrace computer-assisted surgery, computerassisted surgery adds, on average, an additional 10 -15 minutes to the

procedure. Some surgeons perform computer-assisted surgery in less time than conventional procedures.

Is it necessary for all total knee replacements?

Many surgeons employ computers in patients with severe deformity or malalignment. Others believe that computer-assisted surgery is helpful in all patients, not just difficult ones. Precision and accuracy is beneficial in all patients.

time-consuming than standard surgery and requires trained OR personnel. Moreover, many hospitals are reluctant

to spend the money to purchase expensive computer technology. Withthe added OR time, personnel training

and technology costs, it is difficult for many hospitals to offer this procedure.

Can computer-assisted surgery be performed through smaller incisions?

Computer-assisted surgery allows the surgeon to “see” more with the aid of the computer. It is a perfect partner

to smaller incision procedure. Since the surgery is performed with greater accuracy, the patient can reap the

benefit of less invasive procedure without sacrificing precision of the procedure.

Is there additional cost to the patient?

Although computer-assisted surgery costs more to perform, the additional cost is not typically passed on to the

patient. The cost is absorbed by the hospital. Moreover, since potential complications can be pevented and

recovery is accelerated, cost can be contained overall.

Is computer-assisted total knee replacement available at the Minomax knee and shoulder Clinic?

Yes, Dr Ashwani Maichand and his staff are trained in computer-assisted knee replacement surgery.
