what is knee bone graft surgery?

 A Knee bone graft is a surgical procedure that replaces diseased or damaged bones with transplanted bone. This is a choice for repairing almost every bone in the body so your surgeon can take it from your hips and legs to replace it at the knee.

First of all, let’s know some basic things about the body that can help us figure these things out better. The knee is the largest joint in the body. This joint comprises three bones—the lower part of the femur, the upper part of the tibia, and the patella.

Most of the skeleton is a bone matrix to give them their strength. Inside this matrix are bone cells that do the repairing process in case of minor fractures. When a large piece of bone is destroyed, the cells can no longer fully repair it and need external help.

Different types of bone grafts can use in some situations, and some of them are :

  • A minor fracture if it cannot be repaired without a bone graft.
  • Fractures from the past that have not healed and are still bothering the patient.
  • Bone and cancer diseases

Types of Bone grafts in Knee

The basic thing about bone graft in the knee is the same as other types of bone graft, but there are few things you should know about it. There are three types of bone graft that are:

  • Autograft is the bone that takes from another part of the patient's body;
  • Allograft is bones that are taken from other people’s bones;
  • Artificial bone graft that is made from a synthetic bone substitute.

The most common type used for knee bone grafting is an allograft, obtained from long bones, including the arms and legs. One of the main reasons for this very convenient method is that it reduces the risk of infection because there is no need for additional incisions or surgery. In all types of Knee bone grafts mentioned for this surgery, the bone cells die and become powdered because the blood supply is cut off. After that, the powdered bones are transplant between grafts. The living cells of the non-welded area grow on this scaffold and gradually absorb the scaffold, forming a new scaffold instead.

What is peek implant and it 's application in medical area?

  PEEK implants had been used since the 1990s, and it was widely advertised as a biomaterial for implants in April 1998. The initial use o of PEEK implants was for orthopedic purposes especially spinal surgery . We go straight to the PEEK definition; Polyether ether ketone, abbreviated as PEEK, is a semi-crystalline organic thermoplastic polymer. The outstanding properties of PEEK, such as high durability, low moisture absorption, bone-like modulus, load-bearing, thermal resistance, flexibility, toughness, etc. making it a popular and standard biomaterial. History of PEEK Implant PEEK, was first developed for aerospace purposes in 1978. It was widely used in different industries such as aerospace, healthcare, food and beverage, chemical and Pharmaceutical, etc. PEEK had emerged as an alternative for metal implants by the late 1990s, and it was widely advertised as a biomaterial for implants in April 1998. The initial use o of these implants was for orthopedic purposes especially sp...

Spinal Devices Market Demand, Supply, Growth Factors, Latest Rising Trend & Forecast to 2027

The global spinal devices market is expected to reach USD 15.83 Billion by 2027, according to a new report by Reports and Data. The growth of the market may be attributed to the increasing prevalence of target conditions, among other factors. According to the World health Organization (WHO), each year, globally, around 250,000 and 500,000 individuals suffer a spinal cord injury . Preventable causes, including road traffic accidents, falls, or violence, are the major contributors to the spinal cord injury, and individual suffering from the condition are more likely to die prematurely as compared to healthy individuals, with low and middle-income economies having the worst survival rates. Spinal cord injury is linked with a peril of occurrence of secondary conditions, which can be incapacitating and sometimes cost a person’s life, such as urinary tract infections, deep vein thrombosis, muscle spasms, pressure ulcers, osteoporosis, chronic pain, and respiratory complications. As ...

National joint registries show differences in utilization of ankle replacements

 Published results showed marked differences in the utilization of ankle replacement across six countries with national registries. For their study, Thomas A. Perry, BSc, PhD, and colleagues used aggregate data and summary statistics on ankle replacements from national joint replacement registries in Australia, Finland, New Zealand, Norway, Sweden and the United Kingdom between 1993 and 2019. Researchers extracted demographic data on patient age, sex and indications for primary ankle replacement from the annual recorded counts of procedures and obtained registry-level summary results on data completeness, counts of hospitals/units and health care providers performing ankle replacements annually and data collection processes. Researchers calculated the annual ankle replacement incidence for all diagnoses and by indication categories per 100,000 residential population for patients aged 18 years and older. Results showed New Zealand had the largest annual incidence with approximately ...
