Clouding myths pertaining to the post-surgical quality of life of knee replacement has kept many patients with chronic knee pain in the dark. While there is a dire need to raise awareness among the masses about the advancements in technology in his field of joint replacement surgeries, also a minor effort from those undergoing such surgeries to adapt to a healthy lifestyle can also turn out the outcomes to be more fruitful.
During a primary knee replacement surgery, the knee joint is replaced with an implant, which is in most of the cases successful. But sometimes due to loosening of the implants or wear out, a revision procedure may be required. Depending upon the condition, the revision surgeries may include replacement of partial components of the implants, Unicompartmental joint replacement or complete replacement.
According to the recent data provided by Joint registry (ISHKS), over 35,000 total knee replacements (TKR) have been performed in India last year and there is an upsurge in these procedures in the last five years. As per an estimate around 20 crore Indians (especially above the age of 50 years) suffer from some form of knee related problems. The major reasons attributable includes degenerative arthritis like osteoarthritis, Rheumatoid Arthritis, Unicompartmental arthritis among many others. Among such majority of population atleast 20% of them are having a poor quality of life and are suggested for an immediate knee replacement procedure.

Though most of the TKR is sustainable in more than 90% of the cases and have a life of around 15-20 years, but over time if the knee replacement fails due to a variety of reasons. In such cases patients may require to undergo a Revision TKR (RTKR) due to the increased swelling and painful knee joints. The patients may also feel stiffness, the instability that may hinder in their day-to-day activities.

Consult the surgeon when to involve in such activities.
Regular walk – To decrease the chances of re-do surgery, it is important to increase the pace of walking pace and distance after few months of surgery. Walking is purely an individual capacity. At the end of 2 months, one should be able to walk 1-1.5 km per day which can be increased to 250 meters by the end of 3-4 months, till 3 km per day mark is achieved.
Yearly check-ups – TKR patients must visit the surgeons yearly to keep a check on loosening in the joint which can be dealt with time.
