There are a number of conditions that can result in a patient having to undergo knee replacement surgery. Perhaps the most common condition is osteoarthritis, commonly referred to as ‘wear and tear’ arthritis.

If the pain in your knee affects your quality of life, and you can’t be as active as you would like to be, it’s time to take a look into a knee replacement.

Total knee replacement in its current form has been around for over 25 years. In India, popularity has grown over the last 10 years. This is a good operation for pain and correction of deformity in the knee. Results of total knee replacement are excellent with survivorship of almost 95% at 10 years and 85% at 20 years. Like with any profession, the job has to be well done for the knee to survive long and the implant material has to be good too. Most knee implants in India are imported, although of late, one particular Indian brand has been showing promising results.

Most foreign knee implants are broadly similar in design although there are significant subtle differences. Overall functional results are broadly similar no matter what implant is used. More recently, some companies are making many sizes available so that the fit is optimal. These implants tend to be more expensive.

The most common technique of knee replacement is using standard company supplied instruments, which are very accurate. However, to increase accuracy computer guided knee replacement is available but not commonly used, as the functional results have not been found to be any better. Custom made jigs can also be made available for more accurate implantation. This technique has not been very popular as it involves additional cost of an MRI and the lead time is 3 weeks for the jigs to be made in USA and then sent over here.
