There are a number of conditions which can cause knee pain. The most common cause of knee pain is arthritis. “Arthritis” means inflammation of a joint, but in general it describes any condition which causes damage to the cartilage.
If you are severely disabled or in constant pain and your sleep is disturbed, taking the decision would be quite easy for you, even if you have to take certain amount of risk as the potential benefits are worth the risk. The fact is that your knee arthritis will never get better and it gradually worsens as time passes. The rate of deterioration varies from person to person and you may become severely disabled within few months. On the other hand, if you are comfortable with conservative treatment and you are able to walk long distances without support, you don’t require a knee replacement.
Total Hip Replacement
Joint Replacement is not a very recent concept. Arthroplasty or Joint Replacement had its inception in the mid-nineteenth century when surgeons when surgeons attempted to produce extra-articular pseudarthrosis by simple resection of ankylosed joints but failed as these joints were not stable. Several investigators tried Interpositional Arthroplasty with muscle, fat, fascia, Bakelite, Glass, etc.which led to early failures. In 1940, Smith-Petersen developed the Vitallium mould Interpositional Arthroplasty which produced comparatively good results.
Revision Joint Replacement
The replaced joints may fail after 10 to 15 years or occasionally earlier. The parts may wear out or become loose or they may break. The porous surfaces of cementless implants may not properly bond to the bones leading to loosening. In these cases, an operation will be required to replace the damaged part or even the entire implant. Another common reason for revision surgery especially in India is infected joint replacement where the infected artificial joint needs to be removed followed by a waiting period for elimination of infection and later re-implantation.
