The effectiveness of total hip replacement/total knee replacement (THR/TKR) surgery in relieving pain and improving physical function has been well documented.
In addition to improved surgical techniques, the excellent performance of new implant materials and designs has substantially increased the demand for THR/TKR.
| Total Knee Replacement Surgery: |
Total knee replacement surgery offers great relief from pain in the damaged and arthritic knees; and it restores normal activities in life.
Knee replacement is a routine surgery performed on over 650,000 people worldwide each year. Over 95% of people who have had Total Knee Replacement experience an improvement in knee pain and function.
The total knee replacement surgery involves resurfacing the parts of the bones of the knee that have become degenerative and eroded. These are replaced by parts which are metal and plastic implants.
Using special, precision instruments, the surgeon removes the damaged surfaces of all three bones i.e. the upper end of tibia your shin bone; lower part of the femur your thigh bone and the under-surface of patella your kneecap. The replacement surfaces will then be fixed into place using bone cement.
Symptoms of advanced knee arthritis are pain, crepitus, stiffness, limping, muscle weakness, limitation of motion, and swelling. If you have knee deformities or severe X-ray changes, or advanced symptoms of arthritis, you may require a total knee replacement surgery. This is done after the non operative methods like medications; joint injections and other methods have not yielded the desired results, and the activities of the daily living are getting compromised.
The surface of the femur is replaced with a rounded metal component that comes very close to matching the curve of the natural bone. The surface of the tibia is replaced with a smooth plastic component which may be seated in a metal tray. The flat metal tray holds a smooth plastic piece made of ultra-high-molecular-weight polyethylene plastic that serves as the articulating surface of the joint. The undersurface of the kneecap may also be replaced with an implant made of the same polyethylene plastic.
As the damaged and defunct surface of the joint articulating surface is removed and replaced with a metal plastic component of low friction; the pain due to this factor is completely removed and the patient can return to the PAINFREE daily activities.
Demand for joint replacements in young:
As the historical growth trajectory of joint replacement surgeries continues, demand for primary THA and TKA among patients less than 65 years old was projected to exceed 50% of THA and TKA patients of all ages by 2011 and 2016, respectively.The joint replacement surgeries add life to the years by negating the pain and allowing the person to function to the best of her/his abilities.
Cost of knee replacement depends upon the age, gender, implant & preferred accommodation.
