Experts agree that knee replacement is one of the most successful and safest medical procedures in recent times.
Here’s some important information about Knee Replacement and the Implants
- Knee replacement is the most effective treatment for conditions like severe knee arthritis, osteonecrosis or knee injuries that make weight bearing on the knee joint unbearable making it extremely difficult for the person to perform even day to day activities.
- Knee replacement is done to improve the condition and give more decades of functioning to the knee joint.
- It is a surgical procedure in which only the worn out part (partial knee replacement) or the whole of the knee joint (total knee replacement) is replaced with an artificially made implant.
- Knee implants are generally made of metal (titanium or cobalt-chromium based alloys) or ceramic and plastic (polyethylene).
- Some of the recent studies on long-term outcomes of knee implants have found that the implants function well even after 15-20
- More than 90% of the knee implants last for more than 10 years while 80-85% are good even after 20+ years of the surgery. The numbers are improving with improving technology.
- The longevity of the knee implant varies from patient to patient and typically depends upon the physical condition, physical activity and weight of the patient. In addition to this, the skill of surgeon in placing the implant also plays a significant role in the life of the implant
- Practically speaking, knee implant has a high success rate and is considered a safe and effective way to regain knee functionality in terms of routine activities like walking, standing etc.
- Activities like jogging, sports, and other strenuous activities should be considered only after a consultation with the surgeon.
Reasons for Implant Failure
An artificial knee is bound to eventually wear off. The worn out components of the implant can loosen from the bone and cause pain and decreased joint functionality. Loosening is a major reason for the failure of an implant that can be resolved by a revision surgery.
In addition to loosening, any serious complication or younger implant recipients may also require revision surgery.
Revision Knee Replacement
Revision Knee replacement is the surgery to replace the old and worn out components of the implant with the new implant. About 1 person in 10 may need revision knee replacement surgery after 10 years.
Patients who have had a partial knee replacement or are overweight or are involved in heavy manual or weight lifting work are more likely to undergo revision knee replacement surgery.
These conditions fasten the wear and tear of the implant. Just like the rubber of the car tyre wears off if the car is used a lot, the implant also wears off if used more than its capacity.
Average Age for Knee Replacement
There is no absolute or advisable age to undergo knee replacement. Patients who undergo knee replacement are usually between 50 to 80 years of age. However, the orthopedic surgeons evaluate the patient on the basis of his/ her medical condition and advise knee replacement based on that irrespective of the age of the patient.
Time Taken to Perform Knee Replacement
Standard Knee replacement usually takes around two hours for one knee.
Recovery after Knee Replacement
With modern technology and techniques in performing the joint replacement, recovery is fairly quick. Recovery varies from patient to patient and depends on your medical condition before the surgery and any other medical problems that you may have. You would be made to walk a few steps with support the next day of the surgery itself.
It may take anywhere from six to eight weeks before you start walking without support and around 20-24 weeks before you regain full strength and start doing high impact activities.
Cost of Knee replacement without Insurance
If you are staying in a country like the United States, the cost of knee replacement without insurance can be huge. It can cost anywhere between US $ 30,000 to $40,000 for total knee replacement.
