The 10 Fine Print Facts on Yahoo and Microsoft Deal

Yahoo May Terminate Microsoft Search Ad Deal if Revenue per Search Lags Google: "Yahoo may end the Microsoft search ad deal if search engine giant Google's revenue-per-search query rate is higher than both Microsoft's and Yahoo's RPS rates. Microsoft will also hire 400 Yahoo employees as part of its search ad deal with Yahoo, and could end up sharing 90 to 93 percent of the search ad revenues in the second leg of the agreement, according to an 8-K filing from Yahoo.

Microsoft must hire 550 Yahoo employees, whether they need them or not

Did you know that the entire deal is in jeopardy if not completed by July 29 of 2010

Yahoo may terminate its 10-year search ad partnership with Microsoft if the revenue-per-search query rate of Yahoo's and Microsoft's combined U.S. queries falls below a certain percentage of Google's estimated RPS in a 12-month average, according to a filing with the Securities and Exchange Commission Aug. 4.

This provision, which underscores the laser focus Yahoo and Microsoft have on search market leader Google, changes in the second leg of the 10-year term.

Any time after the fifth anniversary of the deal, Yahoo has the right to terminate the search deal if just Yahoo's U.S. RPS is less than a percentage of Google's estimated RPS on a 12-month average.

Yahoo may also terminate the deal if Microsoft exits the algorithmic search or paid search businesses. Moreover, if Microsoft decides to sell its algorithmic search or paid search services businesses, Yahoo will have a 'right of first refusal and right of last offer to purchase such businesses.'

Both companies can quash the deal if it is not hashed out by July 29, 2010."

Using Total Knee Replacement for Knee Arthritis Problems

A knee joint works like a hinge at the junction of two bones, the thigh bone (femur) and the shin bone (tibia). The ends of the bones are covered with a thick cushion of soft, white cartilage. If this cartilage is damaged or worn away, the underlying bones rub together, causing the pain and inflammation of arthritis.

“Arthritis” is an inflammation of a joint causing pain, swelling, stiffness, instability and often deformity. Severe arthritis interferes with a person’s activities and limits lifestyle. The primary reason for a total knee replacement is to reduce pain and to improve your quality of life. It also helps to restore motion, straighten the leg; improve stability and the function of the joint. In total knee replacement, the surface of the joint is replaced with metal and plastic surfaces which can function similar to a normal joint.

This is accomplished by surgically trimming the arthritic ends of the bones and replacing them with new metal and plastic surfaces. In reality, a total knee replacement is a “resurfacing” of the joint. Most of the supporting ligaments, tendons and muscles around the knee joint are retained. The new joint’s surfaces mimic the natural knee it replaces.

Although the idea of getting an artificial knee joint may be intimidating, it is one of the safest and most effective medical procedures,it is important for care givers to know the kind of patients that actually qualify for 'having their knee Replaced" among those afflicted by severe knee Arthritis problems.
What Kind Of Patients Should Have a Total Knee Replacement?

Total knee replacement is recommended for patients with arthritis who have severe pain and limited function which significantly affects quality of life. The most common reason to have a total knee replacement is to relieve arthritic pain. The pain may not be excruciating at any particular time, but it is often chronic and disabling. Everyone’s pain is different, and the degree of pain sufficient to justify surgery should be decided by the patient and the doctor together.

Painful and arthritic knees can become unstable, causing falls and other injuries. Climbing stairs, getting up from chairs and extended walking can also be difficult.

While most arthritic knees are the result of degenerative arthritis or osteoarthritis, other conditions such as rheumatoid arthritis, trauma, prior surgeries, instability and tumors can also be relieved by total knee replacement.

How Long does a Total Knee Replacement Last?

It is next to impossible to determine on an individual basis it is impossible to predict how long a knee replacement will last. With newer materials and techniques, the lifespan of knee replacements continue to increase. The studies of modern knee replacement report clinical survivor ship of up to 97% of total knee implants at 12 to 15 years. A knee Replacement longevity also depends upon factors like lifestyle of the patient among many others..

Benefits of Minmimal Invasive Knee Replacements

In Minimal Invasive technique the incision made is smaller than traditional knee replacement, also in the invasive procedure, the important quadriceps muscle and tendon are not disrupted as in traditional knee replacement. LifeART image ©2004 Lippincott Williams & Wilkins. All rights reserved.

Dr Neelam V. Ramana Reddy,Consultant Wockhardt Hospitals,Hyderabad shares his thoughts about Minimal Invasive Hip Replacement.

Total knee replacement (arthroplasty) is a surgery that is performed for severe degeneration of the knee joint. Knees wear out for a variety of reasons, which include inflammation from arthritis, injury or simple wear and tear arthritis.

Minimally invasive total knee arthroplasty (MIS) is one method of performing a knee replacement. It uses a smaller incision. Unlike conventional total knee replacement, which requires a large incision (8 to 12 inches) and significant disruption of the muscles and tendons. MIS Knee Joint Replacement is performed through an incision as small as 3 to 4 inches. In MIS procedures the amount of soft tissue (muscles and tendons, etc.) that are disrupted during surgery is reduced. Through that same small incision, the diseased surfaces of the knee joint are exposed and then replaced, one at a time, with the artificial joint components. This new technique is also called quadriceps-sparing knee replacement.

MIS Knee Joint Replacement is considered a giant step forward in total knee replacement for a number of reasons, which may include the following: a shorter hospital stay, faster recovery, less pain and much less scarring.

Potential benefits of this new techniques

1. More rapid return of knee function. Patients who undergo this procedure get muscle strength and control back more quickly than patients who have had traditional total knee replacement. This is because the quadriceps muscle and tendon are not divided in the course of the surgical exposure like in traditional knee replacement, and the kneecap is not everted (flipped out of the way) as it is in traditional total knee replacement. The recovery time is much quicker, often permitting patients to walk with a cane within a couple of weeks of surgery or even earlier.

2. Smaller incision. While this procedure would not be worth performing for cosmetic benefits, many patients do prefer the shorter incision. Traditional knee replacement incisions often measure 8” or longer; minimally invasive quadriceps-sparing knee replacement incisions are about 4” in length for most patients.

3. Decreased post-operative pain. This may be a function of the smaller incision and the fact that the incision stays out of the important quadriceps muscle/tendon group. The less-traumatic nature of the surgical approach also decrease post-operative pain and diminish the need for rehab and therapy compared to more traditional approaches.

4.Faster Recovery and Lesser Hospital Stay: Since minimally invasive procedure involves minimal incisions, there is less wounds to heal , which means faster recovery and early return to work.

Minimal invasive quadriceps-sparing total knee replacement is an evolution of surgical technique, which permits the use of time-tested implant designs. This gives some reassurance that while the surgical approach is new, the implants themselves have a good proven track record.

The Surgery would be a preferred choice for most patients, as there is no cost difference between the Conventional Surgery and the Minimally Invasive one. However as with all minimally invasive procedures the patient selection criteria is important, basically chronically deformed joints can not be dealt with, with this kind of surgery.
