Knee articular cartilage damage / osteoarthritis To avoid or delay an artificial knee replacement we fix damaged articular cartilage and repair arthritis using a stem paste grafting technique that stimulates regrowth of damaged surfaces. For over 20 years, we have regenerated damaged articular cartilage to help people preserve their natural joints and avoid artificial replacement.

Overview Artificial knees can wear out. Another risk of knee replacement surgery is failure of the artificial joint. With daily use, even the strongest metal and plastic parts eventually wear out. Joint failure risk is higher if you stress the joint with high-impact activities or excessive weight. Why it's done.

- Minimally invasive partial knee replacement is designed to shorten the traditional incision, lessen trauma to soft tissues, and reduce recovery time. The scar will be about 3-4 inches long on the side of your knee, unless you have previous scars, in which case your surgeon may use an existing scar.

- These have been used to create cushioning systems in modern running shoes. In the 1970's a plastic called 'ethylene vinyl acetate (EVA)' was developed. This material revolutionised the construction of sports shoes. It was made up of tiny air bubbles that provide cushioning and absorbs shock.efore we investigate the type of footwear used by our athletes let's examine a modern football boot. If we look carefully we can see that it is made from a variety of materials chosen because of their individual properties.

Dental Implants Beyond replacing tooth structure below the gum line, artificial dental crowns are used to fill in the gaps of a smile. Custom made crowns are tooth-shaped prosthetics that are made to the exact measurements a patient needs to support adjacent teeth and a healthy occlusion (bite). Crowns serve as the visible portion of a lost tooth and their surface is used for eating food. They are attached via an abutment to the dental implant.

One patient. One implant. One Patient. One Implant. ConforMIS does something that we believe no other knee replacement company does – we design and manufacture customized knee implants, both the femur and tibia, for each patient. No two are alike. Our femoral and tibial implants are individually sized and shaped to fit to each patient’s unique anatomy, offering advantages we believe are not achievable with “off-the-shelf” knee implants.

Below-Knee Amputation During surgery, the leg is amputated at a level that removes as much damaged tissue as possible. There is no single length of amputation that will work for all patients. In general, several inches of leg bone below the knee are required in order for an artificial leg to be properly fit. There is not an advantage to a very long residual leg as it does not improve the ability to fit and wear an artificial leg.

25 Animals With Really Long Gestation Times Here it is; a list of 20 animals whose gestation ( period of pregnancy) is longer than that of humans: Cow: Actually cows are not pregnant for that much longer than humans; they give birth to the calves after 10 months but even one month counts, right? Horse: The typical pregnancy for a mare is around 11 to 12 months. Sea Lion: Sea lions too deliver their pups after a gestation period of 11 to 12 months. The only compensation is that their little ones are really cute. Llama: Again a Llama mama has to carry her young one for about 11 to 12 months.

Lazuriteupdate Lazurite is a tectosilicate mineral with sulfate, sulfur and chloride with formula: (Na,Ca)8[(S,Cl,SO4,OH)2|(Al6Si6O24)]. It is a feldspathoid and a member of the sodalite group. Lazurite crystallizes in the isometric system although well formed crystals are rare. It is usually massive and forms the bulk of the gemstone lapis lazuli. Lazurite is a deep blue to greenish blue. The colour is due to the presence of S 3-anions. It has a Mohs hardness of 5 to 5.5 and a specific gravity of 2.4.
