Does Health Care Insurance Cover Allograft OATS?

Filed under: Knee Surgery — Dale @ 2:00 pm

Be sure to check with your health care insurance company before you agree to have this procedure done. Some cover it; others do not; and still others have stringent criteria that must be met before the procedure is covered.

My insurance company (CIGNA) will cover it if several conditions are met:

CIGNA HealthCare covers osteochondral allograft transplant as medically necessary when ALL of the following criteria are met:

Symptomatic and debilitating focal chondral lesions of an articular surface of the knee are present. Previous medical and/or surgical management has failed. The patient is not currently a candidate for total knee replacement.Other insurance companies have different criteria. Some specify the site and size of the damage to the knee, and some even specify that the patient’s age and even body mass index.

Osteoarthritis of the Knee: Symptoms and Treatment Options (1)

Filed under: Knee Surgery — Dale @ 7:33 pm

Osteoarthritis is a common cause of pain and disability in the knee joint. In the knee, the end of the femur (thigh bone) and tibia (shin bone) are covered in smooth articulate (surface) cartilage. Between the two bones sits a second type of cartilage, called menisci, which acts as a shock absorber. Joint fluid also adds lubrication to the knee joint. Osteoarthritis (OA) starts when articulate cartilage is thinned or missing, which results in areas of exposed bone, and then progresses into surrounding bone, tissue, and synovial fluid.

It has been estimated that 12% of Americans aged 25 years and older have osteoarthritis, which increases to 80% of people older than 75. Symptoms of osteoarthritis include joint pain with activity, night pain, morning stiffness, limited motion, joint inflammation, crepitus or noise from the knee, and deformity. There are several options in treating osteoarthritis, both surgical and nonsurgical. All options are not always appropriate for every patient. Information gained from X-rays, MRI and knee arthroscopy all are helpful in determining an appropriate treatment plan.

Nonsurgical Treatment Options

There are several non-surgical treatments for osteoarthritis; most of them start with weight loss.  Each pound of weight can put up to six pounds worth of pressure on the knee joint during activity, so heavier people tend to develop arthritis at an earlier age and to a greater severity

Muscle strength  is also vital in combating osteoarthritis. The muscles surrounding the knee joint act as shock absorbers for the pressure that daily activities and sports place on the joint. The stronger the muscles around the knee, the more stress they can absorb for the knee joint. Exercises that will increase quadriceps, hamstring and calf strength include ¼ squats, leg press and leg extension. These exercises should be pain free and done with limited flexion or bending of the knee, not greater than 45 degrees. In addition, cardiovascular exercise such as cycling, elliptical, rollerblading, and swimming will also be beneficial. Strengthening exercises should be done at least 3x/week to build muscle strength.

Knee braces are available for treatment of medial compartmental osteoarthritis (arthritis on the inside of the knee joint). These braces work by unloading the medial (inside) portion of the knee. These braces need to be custom made and therefore can be expensive.

Anti-inflammatory medications may also help decrease symptoms. Aspirin, Ibuprofen (Advil) and Naprosyn (Aleve) are all examples of over the counter anti-inflammatory medications (NSAIDs). Prescription strength NSAIDs include Indocin, Daypro, Relafen, Celebrex, Lodine, and Mobic. Acetaminophen (Tylenol) may also be taken for OA pain but it is less effective for inflammation than other medications. Supplements such as glucosamine sulfate and chondroitin sulfate are widely used but not regulated by the FDA. Glucosamine, an aminomonosaccharide, is a primary component of connective tissue (including cartilage). It is not know however, if taking glucosamine orally has any effect on the knee joint. Chondroitin sulfate is found in proteoglycans which contribute to the stability of cartilage. In supplementation form, chondroitin is derived from bovine and calf cartilage. Several clinical studies are in process to evaluate effectiveness, efficacy, and to monitor long term adverse effects of glucosamine and chondroitin.

Lubrication or Hylagan injections provide extra lubrication and shock absorption, as well as decrease friction or rubbing within the joint which may slow the progression of osteoarthritis. However, of all the patients who receive Hylagan injections, only about 50% have symptomatic relief. One injection is given into the knee each week for three weeks and may be repeated as soon as 6 months. Up to five injections may be given, but studies have shown no difference in symptom relief after 3 or 5 injections.
Injection of cortisone into the knee joint has been shown to be effective for ‘flares’ of arthritis symptoms, as they are a direct acting anti-inflammatory medication. However, research has also shown deterioration of articulate cartilage after repeated cortisone injections. Therefore, these injections are only used with caution in the knee joint.

Surgical Options

Artificial joint resurfacing involves capping the end of the femur (thigh bone) and tibia (shin bone) with plastic and or metal pieces. These pieces are glued in place to form an artificial joint surface. This procedure can be very effective in eliminating painful and severe OA, but it is limited by the fact that the articular components (plastic and metal) will eventually wear out and need to be replaced. In active people early loosening of the components can occur. For these reasons most orthopedic surgeons try to delay artificial resurfacing procedures until late in life

Unicompartmental Knee Replacement
Another option for patients with osteoarthritis in one area of the knee- usually medial or lateral is an artificial resurfacing of the cartilage surface, called a unicompartmental knee replacement. This procedure is successful in relieving symptoms from osteoarthritis if the arthritis is limited to one compartment or area of the knee

OATS Procedure
Osteochondral Autograft (or allograft) transplant (OATS procedure) can be performed for small to moderately large area of surface cartilage loss. This procedure involves first removing a cylinder shaped dowel of bone which is lacking surface cartilage and replacing it with a dowel or cylinder of bone with intact surface cartilage. Both dowels are the same size so when they are switched there is a press fit and no hardware is needed to secure it in place. The replacement dowel of bone (with surface cartilage) can either come from a non weight bearing area of bone and surface cartilage from your knee (AUTOGRAFT) or from a cadaver (ALLOGRAFT). If the lesion or area lacking surface cartilage is less than 20mm an autograft OATS may be performed, using either one or a few bone and cartilage plugs. If the lesion to be resurfaced is larger than 20mm, taking tissue from a cadaver or an allograft is needed.

Rehabilitation after an OATS procedure includes using crutches and partial weight bearing activity for 3- 6 weeks.

Osteotomy – Tibial and Femoral
Often patients with knee osteoarthritis may have more arthritis on either the inside (medial) or outside (lateral) of the knee, causing the alignment of the knee joint to shift towards becoming bow-legged or knock-knee. Unfortunately once alignment is no longer even activity and pressure on the knee joint can cause an acceleration of wearing of the vulnerable side of the knee as more and more weight is now transferred onto that area. An Osteotomy is a realignment procedure that unloads the vulnerable or arthritic side of the knee and puts the majority of the load of the knee joint onto the underutilized cartilage on the other side of the knee.

An Osteotomy is performed by wedging open either the tibia (shin bone) or femur (thigh bone) and adding bone graft putty to create new bone growth into the wedged area. After this procedure patients are on a home motion machine for one week, then progress to physical therapy.  They use a brace and crutches for the first 4-6 weeks after surgery until the bone is well healed. This procedure is very successful in relieving symptoms and preventing or delaying an artificial knee in many.

What is Allograft OATS Knee Surgery?

Filed under: Knee Surgery — Dale @ 2:02 pm

Allograft OATS is a surgical procedure for transplanting good cartilage from a cadaver knee into a knee that has lost cartilage from osteoarthritis.

During allograft OATS, the knee is surgically opened up, to expose the affected areas. Measurements are taken of the damaged areas of the knee to confirm the size and extent of the lesion.  Once the appropriate size is determined, a cylinder-shaped dowel of bone is removed from the knee.  It is replaced by the same size cylinder-shaped dowel of bone from the cadaver knee.  In my case, this will likely involved several small dowels, since the inside of my knee is missing most of the meniscus cartilage.  Once the “plugs” are inserted, the knee is closed.

My surgeon will also perform an osteotomy, which is a realignment procedure that unloads the vulnerable or arthritic side of the knee and puts the majority of the load of the knee joint onto the underutilized cartilage on the other side of the knee.

The osteotomy will be done by wedging open the tibia (shin bone) and adding bone graft putty to create new bone growth into the wedged area.

After the allograft OATS and osteotomy, I expect to be on a home motion machine for one week, then will undergo physical therapy for around a month, while using a brace and crutches for 4-6 weeks after surgery.

Following is a link to a good description of allograft OATS with images that help explain the procedure:

Allograft OATS — Waiting for a Call

Filed under: Knee Surgery — Dale @ 1:06 pm

The phone’s not going to ring today.  It’s Saturday, and my doctor’s office is closed.  But each weekday I wait for the phone call that will tell me donor tissue has been received and I’m to report to the surgery center.

The cartilage is missing from the inside of my right knee.  It’s been a long-term process, involving several surgeries, lots of pain, and the realization that I need to take more drastic action to “fix” the problem.  Allograft OATS seems like the best solution for me.

Osteochrondal transplant (OATS procedure) is performed on knees that have suffered large areas of surface cartilage loss (grade IV chrondromalacia).  The procedure involves removing a cylinder-shaped dowel of bone from the knee and replacing it with a dowel of bone with good cartilage.  Both dowels are the same size so when they are switched there is a press fit and no hardware is need to secure it in place.

The replacement bone with good cartilage can come from a non-weight bearing area of the patient’s knee (autograft) or from a cadaver (allograft).  In my case, it will come from a cadaver.  That’s why I’m waiting for a phone call.  A tissue donor with good cartilage will die, my knee surgeon will receive the cartilage from the donor’s knee, and it will be transplanted into my knee.  It’s gruesome, but a remarkable alternative to knee replacement, which is not a good long-term solution for someone my age (55).  Knee replacements tend to last 10-15 years, then a second replacement needs to be performed.  The second one is much more difficult than the first, as less bone is available to work with.

So I’m waiting for the phone to ring …

Becoming a Professional Santa

Filed under: Profile — Dale @ 3:21 pm

It’s hard work being a professional Santa.  It involves long hours filled with inquisitive children, insistent parents, and demanding employers.  Santa pay varies depending on the employer and level of experience.  At the top end, an experienced Santa with a real beard can earn $10,000 – $20,000 for a 5-6 week stint in a shopping mall.  Santas who work private parties usually earn less, anywhere from zero dollars to sky’s the limit.

How to become a professional Santa:

1.  Most importantly, you need to have it in your heart.  Susen Mesco, who leads a Santa School in Colorado, believes Santa must be sensitive and in touch with his nurturing side.  “Children have so little magic in their lives,” she says.  “There are few heroes left in today’s world.”  She advises her Santa students to put glitter in their beards, so children who touch Santa’s beard can take home a bit of the magic.

2.  Professional Santas must believe that the magic they help bring to children overshadows the less glamorous aspects of the job.  Children ask embarrassing questions, pull your beard, and share all sorts of stories (and germs) with you. Teenagers taunt you.  Parents watch you like a hawk and complain if your distress their children.  But you will also bring joy into the lives of children.

3.  You need the proper equipment; which includes a Santa suit, hat, wig, beard, belt, boots, gloves, glasses, and eyebrow whitener.  All of this will set you back between $30 for a used Santa outfit on eBay and $800 for a deluxe size XXL burgundy plush pile “Majestic” Santa suit from McCulloch’s.

4.  It’s best to make sure you are legally covered.  To reduce the odds of legal troubles, Santa Victor Nevada advises professional Santas to keep their hands in plain view at all times, avoid being alone with children, and speak loudly enough that people around can hear what he and the child say to each other.  Santas are also advised not to comment on a child’s hair, eyes, smiles, etc., and to never promise a child they will get what they ask for.  They should also wear non-slip gloves to reduce the possibility of dropping children, and have a parent or guardian place small children on Santa’s lap.

5.  You might want to attend a Santa school, where you would learn a variety of essential Santa skills, including how to deal with difficult or sensitive situations.  For example, when you need to leave your Santa post, it might be best to tell the children in line it’s time to call the North Pole and see how toy production is coming.  When asked, “Are you real?” an appropriate anser might be, “I’m as real as I can be.”
