Facts Concerning A Knee Implant
As one ages, the body naturally wears down. One is unable to engage in the same kind of activity that they would be doing if they were a few years younger. Due to the body’s natural aging and wear process, some parts of the body tend to lose the elastic, while others such as joints become susceptible to diseases and injury.
The knee is one of the most frequently used joints. As a consequence, it is also wears out rather fast during someone’s lifetime. The wear process may be further aggravated due to some pre-existing injury suffered during the course of one’s lifetime. After a while if the pain is serious, a visit to the doctor may result in the recommendation of a knee implant to rectify the problem.
The surgeries involved with replacing one’s knee with a knee implant can be categorized into two: partial knee replacement and total knee replacement. The extent of the damage to the knee will dictate which surgery should be used to perform the replacement. The total knee replacement surgery involves replacing the whole knee joint with a synthetic knee implant. On the other hand, the partial knee replacement procedure involves replacing only the diseased part of the knee while retaining any undamaged parts.
In terms of knee implant designs; there are quite a number of designs currently available. However, the use of each implant will depend on your surgeon’s proficiency in installing the implant, as well as the overall benefits and complications that may arise from using that implant.
Knee implants are designed from a combination of different materials including metals and plastic. The metal part of the knee implant may be made from Cobalt-chrome or Titanium. High density poly-ethylene makes up the plastic parts of the implant. One major problem that affects the selection of which knee implant design to use is the particles produced through wear and tear of the plastic and metal parts grinding on each other. The surgeon will take this into consideration when choosing the implant design.
During the knee implant surgery, the surgeon starts off by fixing the flat metal part of the implant to the tibial bone. Most surgeons may use acrylic cement for this purpose. However, others may use the bone in-growth procedure.
The polyethene component of the implant serves as the new knee bearing surface with the upper metallic part of the implant being fixed into the thigh bone. The bone in-growth procedure may require screws or pegs to hold the implant in place while the bone growth stabilizes. This may result in the implant taking a longer time to heal.
A knee implant could help those who suffer from constant knee pain or diseased knee joints live a more active life.
