Arthroscopic Knee Surgery

Arthroscopy is a common surgical procedure in which a joint is viewed by means of a small camera. The camera is inserted after the surgeon makes a small incision. The arthroscope allows the orthopedic specialist a clear view inside the knee to help diagnose and treat knee conditions. Technological medical advances have afforded our surgeons high resolution cameras and high definition monitors. These and other advancements have made arthroscopic knee surgery an effective means for repairing damage to the knee and treating common knee problems.

What is involved with knee arthroscopy?

During an arthroscopic knee procedure, your orthopedic surgeon will insert a small camera instrument the size of a pencil into your knee joint. This device is called an arthroscope and it sends the image of the inside of your knee to the TV monitor the doctor watches. On this monitor, he can see the knee structures in great detail. This allows him to feel, remove, and repair damaged tissues and structures.

How do I prepare for this surgery?

Be assured, almost all knee arthroscopies are done on an outpatient basis. If your doctor recommends a knee arthroscopy, you may need to undergo a complete physical examination with your family doctor prior to the surgery. He will check your health status and identify any problems that would interfere with the procedure. Before surgery, you should tell the orthopedic specialist about any medications or supplements you are taking. He may tell you to stop taking these a few days before the procedure. You can expect that your surgeon will order some pre-operative tests before the surgery, too. These may include blood counts, X-Rays, and electrocardiogram (EKG).

What type of anesthesia will the surgeon use?

When you arrive to the outpatient surgery center, a member of the anesthesia team will want to speak with you. Knee arthroscopy can be done under regional or general anesthesia. While local anesthesia alone can be used for knee arthroscopy, it is not recommended because of more discomfort during the procedure and the lack of relaxation of the muscles during the procedure which you do get with regional or general anesthesia. Regional anesthesia will numb you below your waist and general anesthesia puts you to sleep. The anesthesiologist will help you decide which type of anesthesia is best for you.

What can I expect during the procedure?

After you receive your anesthesia, the orthopedic specialist will make a few small incisions in your knee. Then, he will inject a sterile solution into the knee joint to rinse away any cloudy fluid that will obscure his view. First, the surgeon will introduce the arthroscope into the knee and use the TV monitor to guide him. If your doctor sees that surgical repair is necessary, he will insert tiny instruments through other small incisions to do this. These could include scissors, graspers, and motorized shavers. Overall, the procedure generally lasts around 30 minutes to an hour. How long it takes really depends on what the surgeon finds and the treatment that is necessary.

Your surgeon will close your incisions with stitches or Steri-Strips and cover them with a dry, clean bandage. You will be moved to a recovery area for about an hour before being released. You will need to have someone there to drive you home.

Knee arthroscopy is most commonly used for:

  • removal or repair of torn meniscal cartilage

  • removal of loose fragments of bone or cartilage

  • reconstruction of a torn anterior cruciate ligament

  • trimming of torn pieces of articular cartilage

  • removal of inflamed synovial tissue

What can I expect during the recovery period?

You will recover from arthroscopic knee surgery quicker than from traditional open knee surgery. It is very important for you to follow your orthopedic surgeon’s instructions carefully after you go home.

Dressing Care – When you leave the hospital, you will have a dressing covering your knee. Be sure to keep this clean and dry. Your surgeon will tell you when it is alright to bathe or shower and when and how to change the dressing. Don’t remove the stitches or Steri-Strips.

Swelling – Keep your leg elevated as much as possible for the first couple of days after your arthroscopic knee procedure. You can apply ice as recommended by your doctor to relieve pain and swelling.

Bearing Weight – Most patients will not need crutches or a cane after knee arthroscopy. Your orthopedic specialist will tell you when you are to put weight onto the leg and foot.

Driving – Your doctor will tell you when you may drive. This decision will be based on several things, including your level of pain, the nature of your procedure, the knee that is involved, whether you have a stick shift or automatic car, and how well you can control your knee. Generally, patients can drive within a few days after this procedure.

Medications – Your doctor will give you medications to help relieve discomfort following your knee arthroscopic procedure. Sometimes, a medication like aspirin is recommended to lessen your risk of blood clots.

What exercises can I do to strengthen my knee?

Your doctor will recommend an exercise program for you following your arthroscopic knee surgery. This is done to restore motion and strengthen the muscles of your knee and leg. Therapeutic exercises are important for a speedy recovery. Sometimes, the surgeon finds it necessary to set you up for formal physical therapy to improve your final result.

When can I get back to my normal routine?

Typically, you are able to return to your normal physical activities within 4 to 8 weeks. Higher impact activities, such as running and aerobics, may need to be avoided for a longer periods of time. You will need to discuss this with your orthopedic specialist to make sure you don’t further damage your knee joint. The final outcome of your surgery is largely determined by the degree of damage to your knee.

Top Thrill Dragster roller coaster in Ohio, US permanently closed following serious accident

Friday, September 9, 2022

On Tuesday, September 6, Cedar Point amusement park in Ohio, United States announced that Top Thrill Dragster, the second tallest-roller coaster in the world, has permanently closed. The ride was the first full-circuit strata coaster, a roller coaster exceeding a 400 feet (122 m) height limit, in the world.

Director of communications at Cedar Point, Tony Clark, released a statement that “after 19 seasons in operation … the world’s first strata coaster, Top Thrill Dragster … is being retired.”

The news comes after an accident on August 15, 2021, when an L-shaped bracket fell on the head of a guest in the queue line, causing a serious brain injury and leading to the closure of the attraction for the rest of the 2021 and 2022 seasons. The bracket was later identified as a sensor used to detect where the cars were on the track.

The park was cleared by Ohio officials in February 2022 of any wrong-doing or of having reason to believe that the ride was unsafe before operation. Prior to the August 2021 accident, two guest-related accidents occurred on the attraction.

Although the ride has been retired in its current form, park officials have stated that they are working on “creating a new and reimagined ride experience.” It was not confirmed if it was the accident that led to the permanent closure of the attraction.

World stocks plunge on fears on US recession

Monday, January 21, 2008

The Hong Kong Stock Exchange

Stock prices dropped sharply in Europe and Asia Monday, with fears of economic problems in the United States causing some of the biggest single-day losses in recent years.

In Hong Kong, the Hang Seng index fell 5.5 percent – its biggest fall since the September 11, 2001, terrorist attacks. Losses of between three and seven percent were recorded in India, China, Britain, France, Germany and Canada.

While there are many factors linking national economies, analysts blame recent losses on fears of a recession in the United States.

The United States is the main export market for many overseas businesses. Foreign investors also have bought large stakes in U.S. companies.

When American home loan companies began reporting large numbers of defaulting loans in late 2007, the losses spread to other financial institutions, tightening credit markets and sparking worries about Americans’ high levels of debt.

Last week, President Bush proposed a $145 billion stimulus plan to encourage more consumer spending. But analysts say the measure may not be able to prevent a recession – defined as a broad decline in a nation’s economy over a period of at least six months.

U.S. markets are closed on Monday for Martin Luther King Jr. Day, a national holiday, but stock futures trading indicates further losses are expected when markets reopen Tuesday.

Yahoo announces closure of Briefcase

Tuesday, February 3, 2009

Yahoo!’s headquarters in Sunnyvale, California Image: Coolcaesar.

Yahoo!’sNASDAQYHOO Briefcase service is to be closed after ten years.

The directory-cum-internet portal’s Briefcase, which offers 30mb of online storage of files up to 5mb, is to be shut down on March 30. Data not retrieved before then will be deleted.

Usage of the service has declined in recent years and has been superseded by other companies’ offers. Google has plans for a GDrive service, whilst Microsoft’s Live Mesh is now in beta. Yahoo! Mail now has unlimited storage, as do paid accounts with the Yahoo!-owned photo- and video-sharing site Flickr. A spokesperson for Yahoo! said that “[d]iscontinuing the service will allow us to focus our efforts on more broadly used products”.

Yahoo has been losing market value since Microsoft’s deal to buy the company fell through in May 2008 and the company has reduced staff. Yahoo! still dominates the market for display adverts but this market is shrinking against targeted search adverts, where Google dominates.

Nepal Parliament passes resolution to curb King’s power

Thursday, May 18, 2006Prime Minister of Nepal, Giriraj Koirala proposed in Parliament a resolution which is aimed at drastically curtailing the monarch’s powers. According to the resolution, the King will be stripped of his status as the Supreme Commander of the Royal Nepal Army (which is to be renamed as the Nepal Army Cabinet). Portions of the Nepalese national anthem that praise the King have been cut.

The proposal also aims at cutting down on the King’s allowance and his right to be exempted from paying taxes. The government which is currently referred to as the “King’s administration” will henceforth be known as the “Nepalese Government”. The resolution also changes Nepal’s status from that of a Hindu nation to a secular one. The King’s Advisory Council will no longer exist and his security will be taken care of by Parliament. The King will also now no longer have the privilege of being above the law of the land since the resolution provides for him to be tried in court if the situation so warrants.

Analysts have expressed concerns saying that under the current Constitution, this proposal cannot become law till the King signs it. Politicians say however that this proposal is above the Constitution and reflects the will of the people. King Gyanendra restored democracy to the Himalayan Kingdom after weeks of massive anti-monarchy protests earlier this year.

Final launch of Space Shuttle Discovery delayed until at least Thursday

Wednesday, November 3, 2010

Space Shuttle Discovery’s final launch on the STS-133 mission to the International Space Station has been delayed at least an additional day. Launch is now targeted for 3:29 PM EDT on Thursday.

The launch was originally scheduled for this past Monday, but was delayed two days because of helium and nitrogen leaks on board the shuttle.

Technicians are now working to repair technical glitches discovered yesterday on a main engine control computer.

The weather outlook, however, appears to be unfavorable for the new targeted launch day; there is an 80 percent chance of undesirable weather, according to the NASA space shuttle weather officer Kathy Winters.

The mission management team (MMT) is meeting today to discuss and troubleshoot Discovery’s newfound electrical problems.

STS-133 is scheduled to be an 11-day mission to the International Space Station to ship supplies to the crew, as well as additional components for the orbital outpost’s construction, including the Permanent Multipurpose Module and the third of four ExPRESS Logistics Carriers. The mission is the 133rd of the Space Shuttle Program and the 39th of Discovery.

Existing and planned gas pipelines in Europe

A 30 meter section of a gas pipeline in Luka (near Kiev) in Ukraine has been destroyed by an explosion. Although supplies to Europe via this pipeline have stopped, Ukrainian Energy Minister Georgi E. Boyko said that supplies to Europe would not be affected.

“There are no changes in volumes of gas being transported,” Yuri Korolchuk said. “Volumes due to pass through the damaged section are being redirected through the Soyuz pipeline.”

Normal flows are reported in the Czech Republic, Hungary, Poland and Romania.

A scrap of copper tubing

Copper prices are rising. Between record copper imports from China, and a mining strike in Peru, the prices have climbed to over $8100 (United States dollars) a tonne, for a gain of $575 dollars over the last week. However the upward trend is not new, it has been climbing for quite some time. In April 2003, the price of copper was under $2000 a tonne.

The metal market has been tending up due to growth in the Chinese industrial production. This trickles down to the local level, where the buying price at scrap yards is ever climbing, making scrap metal collection a more profitable endeavour for individual people using pick up trucks or other such vehicles to collect and cash in the scrap metal at metal buying yards. It can be collected via agreements with businesses, from the garbage, or, sometimes, by theft.

Copper prices fell today on the NYMEX commodity exchange from US$3.7545 per pound to US$3.7125 based on the July futures contract.

Luxor Hotel in Las Vegas

One man was killed and another injured by an exploding backpack in the parking lot of the Luxor Hotel in Las Vegas, Nevada. The explosion happened at 4 a.m. PDT when the victim tried to remove a the object left on top of his car.

Agents from the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) are on the scene. Aerial images did not show any apparent damage.

“We believe the victim was the intended target of this,” Bill Cassell said, spokesperson for the Las Vegas Metropolitan Police Department. “This is being treated as a homicide in which the weapon used to cause death is a non-traditional weapon.”

Both of the victims worked at the Luxor.

Scientology protest group celebrates founder’s birthday worldwide

 Correction — March 19, 2008 The next protest is scheduled for April 12, 2008. The article below states April 18 which is incorrect. 

Saturday, March 15, 2008

The Internet group Anonymous today held further protests critical of the Church of Scientology.

The global protests started in Australia where several hundred protesters gathered at different locations for peaceful protests.

In a global speech, the Internet protest movement said Scientology “betrayed the trust of its members, [had] taken their money, their rights, and at times their very lives.” The protesters welcomed the public interest their protests have led to, and claimed they witnessed “an unprecedented flood of Scientologists [joining] us across the world to testify about these abuses.” The group said it would continue with monthly actions.

In a press statement from its European headquarters, Scientology accused the anonymous protesters of “hate speech and hate crimes”, alleging that security measures were necessary because of death threats and bomb threats. This also makes the Church want to “identify members” of the group it brands as “cyber-terrorists”.

Wikinews had correspondents in a number of protest locations to report on the events.

Anonymous states that the next protest is scheduled to take place on April 18, which happens to be the birthday of Suri, the daughter of Tom and Katie Cruise.

US stock markets reach 12-year lows

Thursday, March 5, 2009

Logarithmic graph of the Dow from January 2000 through December 2008

US stock markets dropped to twelve-year lows on Thursday, amidst falling confidence in the financial sector and worries over whether the US automobile manufacturer General Motors will be able to keep operating.

The Dow Jones Industrial Average dropped by 4.08%, or 280.52 points, at the closing bell, reaching a level of 6595.32, a new 12-year low. The Nasdaq Composite lost 54.15 points, or 4%, to 1299.59, while the Standard & Poor’s 500 plunged by 30.27 points, or 4.25%, closing at 682.60.

Every stock in the Dow Jones, other than Wal-Mart, either lost ground or remained even, and all stocks in the S&P 500 index lost ground.

General Motors’ shares lost 15.5% after the auto firm announced that its auditors had “substantial doubt” over whether it would be able to keep operating.

Shares of financial companies were lower by nine percent, with Bank of America losing 11.7% and Citigroup falling by 9.7%.

“What’s most worrisome is that we haven’t hit the crescendo yet,” said Bill Groeneveld, the head trader for vFinance Investments. “Asset-management divisions are getting calls to just liquidate everything, and we haven’t seen the big players come back in at all.”

“This is one of the worst bear markets in the last 100 years; it started out with the credit crisis and the subprime [loans], but it is like a forest fire that has raced across the clearing and ignited other parts: Autos, auto parts, the insurance companies have been hit very hard. The credit crisis is causing an unraveling of industry after industry because the banks don’t lend,” said David Dreman, the chief investment officer of Dreman Value Management.

European markets were also lower today, with the London’s FTSE index losing 3.2% and the DAX index of Germany falling by five percent.
