Knee transplants may be treatment for knee pain


January 11th, 2010 by Formosa Medical Travel

As osteoarthritis continues to afflict more and more Americans, sufferers turn to different treatments to ease the pain and regain mobility. Although knee replacement surgery is considered the most effective and long-lasting treatment to knee pain, an advanced procedure is being pursued by some younger patients: knee cartilage transplantation.


Osteoarthritis causes the deterioration of the cartilage in the knee. The cartilage serves as a load bearing zone and allows for flexion of the joint. Unfortunately, cartilage has poor regenerative qualities and, once afflicted by osteoarthritis, can degenerate quickly. Once osteoarthritis has progressed to an advanced stage, simple tasks such as walking can prove very painful or even impossible.


In performing a cartilage transplant, doctors first must perform a biopsy. In this minor surgery, surgeons take a sample of knee cartilage from the non-essential area — that is, the zone that does not bear weight. The biopsy is then taken to a lab, where it is cultured and grown into millions of cartilage cells.


The cultured cells are then used to replace the damaged knee cartilage, in a more-invasive surgical procedure. Once the undeveloped cartilage cells have been re-inserted, a period of about three months is necessary for them to continue the healing process and replace the damaged area of the knee.


Younger patients are more suited for cartilage transplants than older ones. Some doctors recommend that the operation only be pursued by patients in their 20s, 30s, and early 40s, while older patients should consider either partial or total knee replacement surgery.



Common misconceptions about total hip and total knee replacement surgery


November 23rd, 2009 by Formosa Medical Travel

Osteoarthritis is the most common cause of knee and hip pain, afflicting an estimated 40 million Americans. Also known as degenerative joint disease or degenerative arthritis, osteoarthritis can cause the deterioration of both the knee and hip. As the US population continues to age, it is estimated that osteoarthritis will affect as many as one in five Americans by the year 2020.


Although osteoarthritis is not life-threatening, it does have significant effects on the quality of life of those who suffer from it. While non-surgical treatments such as anti-inflammatory drugs – i.e. Naproxen, Aleve, Proxen, etc., and joint fluid injections (such as Hyaluronan, Synvisc, and Synflex) can delay the need for surgery, the only long-term solution is total joint replacement surgery.


There are a number of misconceptions about total hip replacement and total knee replacement surgery. The most common is that total knee replacement and total hip replacement are highly-dangerous procedures. In reality, total knee replacement and total hip replacement surgery have the highest success rates of any elective surgeries performed today.


Currently, the vast majority of knee and hip replacement surgeries are performed in minimally-invasive fashion. This allows for minimal scarring and faster healing times, while maintaining the same success rate. While some believe that minimally-invasive procedures may result in different outcomes, the data show that these procedures are equal to their more-invasive counterparts – the only difference being the size and appearance of the incision.


Another misconception is the idea that joint replacements can only last as long as twenty years. This is not necessarily the case. The reason for this is, of course, that the data being used for this assumption is based on knee and hip replacements that were performed twenty years ago. Research is constantly being done to increase the performance of joint replacement devices, and a great deal of time has gone into developing improved models. New production methods and materials will likely increase the lifetime of hip and knee replacements in the future.
