Takeaways from Dr. Bradbury’s Hip and Knee Replacements Chat

Thank you for participating in the online chat on Hip and Knee Replacements.  We had a lot of really great questions.  We received a few questions a couple times so we will highlight the answers to those questions here!

What is the longevity of knee replacements?

The lifespan of a knee replacement is related to the body weight and activity level of the individual who receives the replacement.  Individuals who are very active often reduce the longevity of their knee replacement because high activity can put extra stress on the implant leading to loosening of the implants from the bone or “wearing” of the parts used to replace the joint.  Being overweight increases the forces on implant and can also lead to early failure.  In general, 15 year survivorship of modern knee replacement designs used in  good candidate is around 90 percent.

Typically for younger patients,  if x-rays do not show complete loss of cartilage, “bone on bone”, I recommend waiting as long as possible to have the knee replacement surgery.  However, if there is “bone on bone” arthritis, knee replacement is the most effective treatment, but the risks of early failure are increased.

What exercises can I do for a total knee replacement?

Low impact aerobic conditioning 4-5 times per week for 4-6 weeks prior to surgery is best.  Low impact activities include swimming, elliptical, or stationary  bike.

“Prehabilitation” is rehabilitation to get your body ready for the surgery so you can recovery as quickly as possible after surgery.  Instruction during this period should be focused on strengthening the muscles around the joint.  The prehabilitation period should last for several weeks before surgery.

How long is recovery after hip/knee replacement?

It is best to think of how long it takes to reach recovery milestones -

• For hip replacement, pain is typically better than what it was prior to surgery in 2-3 weeks, normal walking typically occurs by 6-8 weeks and full recovery typically occurs within 3-4 months.

• For knee replacement, pain is typically better than what it was prior to surgery by 4-6 weeks, normal walking typically occurs by 8-10 weeks and full recovery typically occurs within 4-5 months.

Thank you again for attending the chat. I hope you found the information useful!  If you have questions or would like to schedule an appointment with an Emory Orthopedic Surgeon about hip or knee replacements please call 404-778-7777.

Osteoarthritis Pain Treatment – Using your own Stem Cells?

hip resurfacing procedureIt is reality now! Physicians at Emory Orthopaedics & Spine are among a select group of physicians around the country to offer a unique procedure using stem cell injections to relieve osteoarthritis (OA) pain. During the procedure, the physician extracts stem cell blood from the bone marrow in a patient’s hip and then injects the stem cells directly into the patient’s damaged joint. The stem cells are from the patient’s own body so the risk of rejection is very low.

Hear first hand from Dr. Mautner and one of our patients how this new treatment option is helping relieve pain from Osteoarthritis:

Orthop(a)edics 101

Orthopedics 101Is it “orthopaedic” or “orthopedic”? What does “musculoskeletal” really mean? What’s the difference between a ligament and a tendon? Today we’re going to answer some of the more pressing questions people have about this fascinating area of medicine.

First off, let’s discuss the use of orthopaedic v. orthopedic. Orthopaedic is derived from the Greek orthos, for correct or straight, and paideion, for child. Today, orthop(a)edics refers to the correction of spinal and bony deformities in both children and adults. In the U.S., we like to keep things simple, so “orthopedics” has become the standard spelling. In Great Britain and its other former (non-U.S.) colonies, orthopaedics is preferred. The academic world, like the Brits, enjoys fancying things up, so in most universities and other academic settings, orthpaedics stands. Microsoft Word prefers it without the “a.” Take your pick.

Simply put, orthopaedic (or orthopedic) surgery is the branch of surgery concerned with conditions of the musculoskeletal system. What’s the musculoskeletal system? Clearly, it’s a system that involves the muscles and the skeleton. Also called the “locomotor system,” the musculoskeletal system includes the parts of your body that help you move. And help you stay in one place. The bones provide stability, while the muscles help the bones stay in place and move. Joints allow motion, and cartilage keeps the bone ends from rubbing against one another. It’s all about how bones are connected to other bones and joints and muscles by connective tissues called tendons and ligaments.

What’s the difference between a tendon and a ligament, you ask? A tendon (or sinew) is a tough band of tissue that connects the muscle to the bone. A ligament connects bones to other bones. But wait—let’s not forget the fascia. The fascia is a layer of fibrous tissue that surrounds muscles and groups of muscles, as well as blood vessels and nerves, and binds all of these together. The layers of fascia include a superficial fascia (connected to the dermis, or skin), a deep fascia (surrounding the bones and muscles), and a subserous, or visceral, fascia (supporting the organs).

The surgeons and physiatrists at the Emory Orthpaedics & Spine Center are intimately familiar with every aspect of the musculoskeletal system and can diagnose and treat myriad ailments, both surgically and nonsurgically. So if you’re hurting, whether from a broken bone or a stretched or torn ligament or tendon, come see us. With or without the “a,” we know our orthop(a)edics.

Got Hip Pain? Get Back in the Game Quickly with Hip Resurfacing

hip resurfacing procedureIn my practice at the Emory Orthopaedics & Spine Center, I see a lot of patients who suffer from hip pain as a result of osteoarthritis, or degenerative joint disease. In the past, when surgery was called for, hip replacement was often the best option—and in many cases, it still is. However, in 2006 the FDA approved the first total hip resurfacing implant in the United States, allowing patients suffering from serious hip pain another highly effective option.

Unlike total hip replacement, in which the diseased head ball of the hip (femoral head) is completely removed, total hip resurfacing preserves the femoral head and removes only the damaged surface of the bone.

Only a small number of surgeons in the Atlanta area have the training and expertise to perform this procedure properly. I have been performing total hip resurfacing procedures at Emory since 2007, with excellent patient outcomes. This specialized operation has a number of potential advantages for the right patient. Total hip resurfacing can:

  1. Preserve bone
  2. Restore the natural anatomy of the hip
  3. Provide the largest possible head size to improve hip stability
  4. Enable restoration of hip function to allow a multitude of activities
  5. Allow for an easier revision (re-do) in the future, if needed

So who’s the perfect hip resurfacing patient? Hip resurfacing is best suited for the young, active male (<55 years of age) with osteoarthritis of the hip and normal hip anatomy. Healthy and active at 45, Mark Gabriel was the ideal candidate. I met Mark last year, after he’d been suffering from pinching and pain in his hip for a year and was referred to me for surgery. Mark, a director for an Atlanta IT solutions and staffing company, was in great shape, save for his hip. His hip pain had resulted in large part from 40 years of playing tennis on hard-surface courts. As he put it, his hip was like a brake pad that had been used too much. Eventually it wore out. Resurfacing his hip was a great way to preserve the hip bone and allow Mark to get back to the active lifestyle he enjoyed.

In July of 2009, I performed Mark’s hip resurfacing surgery at Emory University Orthopedic & Spine Hospital (EUOSH), our state-of-the-art inpatient facility. Mark was put under general anesthesia for the procedure, which went smoothly and took about two hours. Because Mark is young and had stayed active by cycling up to his surgery date, he recovered from the surgery quickly. He stayed in the hospital just two nights and was off pain medication completely three days after surgery. After six days, he was down to one crutch and was back to walking around his neighborhood.

Mark says that he is 100% satisfied with the results of his hip resurfacing. In the year since the procedure, he’s played tennis five days a week, enjoyed golf, and gone skiing. He chooses clay courts over hard surface when he has the option, but Mark is back in the game and loving life after hip surgery.

Improved Joint Capsule Reconstruction Results in Fewer Dislocated Hips

James Roberson, MDDislocation of the ball from the joint has always been a possible complication following hip replacement surgery. However, at Emory Orthopaedics, a couple of developments have significantly reduced, if not eliminated, those concerns.

One of these developments is the use of alternative bearing surfaces such as highly cross-linked polyethylene—a super-wear-resistant plastic—which enables surgeons to use larger-diameter balls (femoral heads) in the hip joint. The new, thinner bearing surfaces allow for larger-diameter femoral heads, making the hip intrinsically more stable.

Another development that has significantly increased hip stability is recognition of the importance of reconstructing the ligamentous capsule of the hip joint to its appropriate anatomic position at the completion of the hip replacement. The hip is held in place by the soft tissue around the hip—the capsule, the ligaments, and the tendons. If these are not put back in an anatomic position (i.e., where they came from), the hip will have a greater chance of dislocation.

At Emory Orthopaedics, what these developments mean is that we have become more comfortable allowing our patients to resume natural activities earlier after surgery. Traditionally, patients were told they shouldn’t bend their hip more than 90 degrees, shouldn’t cross their legs, should use an elevated toilet seat, etc. for up to three months following surgery. Patients were apprehensive about dislocating their hip. But with these new materials and improved methods, for most patients we’ve stopped using those restrictions in the early post-op period. Now we feel confident telling patients that they can sit however they’d like to, bend their hips, and so on. They can go straight to enjoying their new and improved hip.
