What You Should Know About ACL (anterior cruciate ligament) Reconstruction

May 18th, 2018 Comments off

The anterior cruciate ligament (ACL) is located in the knee. When it is torn, it can be extremely painful. The treatment for this sort of injury is reconstructive surgery. This procedure replaces your torn or damaged tissue with new tissue.

Autograft is the term used to describe a graft that is taken from your body. An autograft is usually taken from part of the tendon that is located on the front of your knee. This is called the patellar tendon. Another place an autograft may be taken is the hamstring.

Allograft is another type of graft. This tissue is harvested from a cadaver.

There are both advantages and disadvantages to the use of each type of graft. Your surgeon will determine which type will work best for you.

ACL (anterior cruciate ligament) is usually performed using arthroscopy. This is a type of surgery that utilizes a miniature camera to image the interior of the knee. The camera is introduced into the knee chamber via a poke-hole or small incision. This method lets the surgeon get a clear view of the knee chamber.

While your surgeon is looking, he or she will check for damage to other tissues. If the cartilage or ligament in your knee has been otherwise damaged, that problem will also be attended to during your procedure.

The most commonly used anesthesia for arthroscopic knee surgery is general anesthesia. With general anesthesia, you will sleep through your surgery and wake up with a brand new ACL (anterior cruciate ligament)!

Your surgeon will also make a few other small incisions around the knee. These will allow the surgeon to place your new ligament properly. Your damaged ligament will be taken out with a shaver or some other instrument. The exception to this is that, if you will be using an autograft, a larger incision will be needed to remove the tissue that is to be used for grafting.

Your surgeon will create bone tunnels to be used in placing the new ligament in the exact location of the old ligament. Once the bone tunnel is in place, your new ligament will be positioned and attached to the bone with screws or some other form of fastener. This will hold the ligament in its proper place. At the end of surgery, your surgeon will close your incisions and apply a bandage.

Your surgeon will probably take photos and/or film your operation so that you can watch it on the video monitor after your surgery is done. This technique allows the surgeon to discuss findings with you in detail.

To be considered for ACL (anterior cruciate ligament) reconstruction, some symptoms you might be experiencing include, knees that give way, weakness and instability in the knees, and knee pain. If your ADL (activities of daily living) are affected and/or you are not able to participate in sports as you wish, these are further reasons to consider ACL (anterior cruciate ligament) reconstruction.

As with any surgical procedure, there are some risks involved. Excessive bleeding, nerve damage and infection occasionally occur. Patients also report weak knees and pain and stiffness in the knees. Sometimes, the surgery does not resolve the symptoms. Occasionally, the ligament does not heal.

Gastric Bypass Surgery: The Physical And Emotional Effects

October 6th, 2014 Comments off

Gastric bypass surgery is class of procedures used to treat morbid obesity and the resultant health problems. Morbid obesity is defined as having a BMI of over 40 but less that 50. The adverse effect that this excessive fat can have on other body systems may result in heart disease, diabetes, sleep apnea, and joint problems due to overburden. Apart from the medical complications, obesity is also associated with low self-esteem and depression. The burden of obesity in industrialized countries is great. According to recent estimates, the number of individuals in the U.S. who are obese is huge, more than 30%, and this number keeps increasing. About 3% of people (6.8 million) were found to be morbidly obese in 2005, which is significantly up from 2 % (4.2 million) only five years previously. (RAND 2005) modest results, at best, are seen with diet drug such as orlistat. This has fueled interest in other modes of treatment such as bariatric surgery. Gastric bypass surgery (GBP) is the most common procedure (65%) that is carried out, but comes with its own risks and side effects.
The procedure aims to reduce the capacity of the stomach by dividing it into two sections and creating a connection to the small intestine and the first section. This connection can be made in different ways and so there are various subtypes of this procedure. This way less food can be eaten comfortably and less calories absorbed, and the physiological and psychological response to food is also changed. Success rates for this procedure are around 75%, and the average person loses at least half of the excess weight in a period of 18 months. Around fifteen thousand people undergo this procedure every year in the United States.
As with any procedure, there are a number of complications related to it; bad technique or failure of surgery resulting in hernias, abdominal leaks and abscesses requires about 20% of the people who have had GBP to undergo additional procedures. The overall complication rate is 7% for laparotomy and around 14% for open incision procedures in the first month post surgery. Another phenomenon known as the ‘dumping syndrome’ may occur. This happens because the pyloric valve at the end of the stomach is no longer used to control the amount of food that passes into the small intestine. Therefore, whenever a sugary meal is eaten, it quickly passes into the bowel causing symptoms such as increased heart rate, sweating and anxiety. This uncomfortable state persists for about 30-45 minutes.
Intolerance to food such as milk or red meat post GBP may result in nutrition deficiencies such as anemia and osteoporosis that 30% of patients suffer from. Hyperparathyroidism from lack of absorption of calcium, and supplemental Vitamin D has to be taken. Neuropathies results from Vitamin B12 deficiency, as an important chemical that aids absorption, produced by the stomach is itself deficient.history essay
