What is arthritis?
Arthritis is a general term used to describe the loss of cartilage from joint surfaces or the ends of bones that move against each other. When the cartilage loss is significant enough to be visible on an xray and causes joint pain, we say that the joint has arthritis. Cartilage can be worn away through wear and tear, and this etiology is termed degenerative arthritis or osteoarthritis. Cartilage can also deteriorate due to inflammatory arthritis (such as rheumatoid arthritis), trauma, or infection.

What is total joint replacement?
A joint replacement is a surgical procedure that removes the damaged bearing surfaces of a joint and resurfaces it with artificial materials. The implants that replace the joint surfaces are attached to the bones either with bone cement or via biologic bone growth into porous surfaces on the implants themselves. Joint replacement is widely successful and is available for the hip, knee, shoulder, elbow and ankle joints. For detailed information on hip or knee replacement, download our hip brochure or knee brochure.

What are the benefits of total joint replacement?
Joint replacements relieve pain, reduce stiffness and restore function. An arthritic joint is painful because the nerve endings in the bones on either side of the joint that are normally covered with cartilage have become exposed due to cartilage loss. These joints are often stiff, due to the formation of bone spurs, extra fluid production by the lining of the joint and contraction of the joint capsule in the presence of prior injury. A joint replacement relieves pain because it eliminates the bone against bone contact in the damaged joint, so the nerve endings are no longer stimulated. Stiffness is reduced through removal of bone spurs and the reduction in the production of synovial fluid that come with a healthier joint. Relief from pain and stiffness means that our patients can return to more active lifestyles.

How do I know if I need a joint replacement?
An evaluation by a physician is useful if you have hip or knee pain, joint stiffness, limitations in activities, trouble sleeping, or decreasing function. When simple measures such as the use of anti-inflammatory medications or injections are no longer effective, it is time to give us a call. We often recommend that our patients make a list of the things they cannot do as well as they would like, and when that list is too long to live with, surgery may well be the answer. A physical examination and xray will allow us to discuss with you whether joint replacement is next appropriate treatment option.

I have knee arthritis, but is total knee replacement my only option?
For patients with arthritis isolated to a single compartment of the knee, partial knee replacement may be a surgical option. While total knee replacement has excellent outcomes, the benefits of partial over total knee replacement include a less traumatic operation, preservation of bone and ligaments, less blood loss, potentially better knee range of motion, faster recovery, and a more normal feeling knee. Early detection is important with a thorough physical exam and radiographic studies to determine if partial knee replacement is appropriate.

What are the risks of joint replacement?
All surgery poses certain risks. Fortunately, the chance of a significant complication with joint replacement is very low. The risks specific to hip and knee replacement surgery involve primarily the cracking of the bones during the preparation or implant insertion process. Blood clots in the deep veins of the legs can also develop after surgery, although this is very unusual. Rarely, a clot in the leg can travel to the lung. Other risks that can occur with any type of surgery include damage to nerves and blood vessels and infection., Allergy to the implant materials is exceptionally rare, described on a case report basis. For a complete discussion regarding the complication rates after joint replacement surgery, please download our hip brochure or knee brochure.

How long does a total joint replacement operation take?
Primary joint replacement, as opposed to revision joint replacement, generally takes less than an hour in the hands of a specialist. The steps involved in both hip and knee replacement are consistent and easily streamlined in a high volume setting. Speed is important, since infection rates are directly linked to the amount of time the skin is open. Accuracy is even more important, however. Because of the narrow focus of our program and our tremendous experience, we have been able to combine accuracy and a streamlined approach to surgery, producing speed as a by-product.

How many joint replacements do you perform each year?
Over 1500 joint replacements are performed yearly at the Institute for Joint Restoration. Many studies have shown that improved outcomes with reduced complications are achieved when joint replacement is done by high volume surgeons, at high volume hospitals. In contrast, the majority of joint replacements performed in the US are performed by surgeons who replace fewer than ten joint per year.

Where would my surgery be performed?
Most total joint surgeries take place in the modern, efficient operating rooms at Washington Hospital in Fremont, California. The Institute for Joint Restoration is housed there, in the Center for Joint Replacement building, a hospital within the hospital. Select total and partial knee replacements may be performed at the Washington Outpatient Surgery Center, primarily for patients expecting to be discharged the same day. Although we have, over the years, performed surgery at other locations, no facility can match the early outcomes coming out of the Washington Hospital Healthcare System.

Is your Institute a teaching hospital?
Yes and no. We do not teach medical students or residents at our facility, although many orthopaedic residents hear our presentations at national meetings and read our research studies. Research and teaching is a valuable part of what we do, but we believe that until resident physicians master the anatomy and surgical techniques through performing hundreds of operations, they should be operating through larger incisions than we employ and require constant supervision. We do, however, participate in the teaching of practicing orthopaedic surgeons who want to refine their techniques or learn more streamlined methods for joint replacement care. We regularly host site visits and have the operating rooms equipped with video cameras and monitors for teaching purposes. Visiting surgeons are there to observe only and their presence in the operating room requires patient consent. Many of our patients take advantage of our video system and observe their own surgery.

Do you employ Physician Assistants (PAs)?
Yes we do. Our PAs are highly skilled and experienced orthopaedic specialists. They know more about joint replacement surgery than most orthopaedic residents and many attending physicians, and they function a bit like residents in our program. They participate in the preoperative and postoperative care of our patients, they assist in surgery, and they help our patients get their questions answered more quickly and efficiently. Unlike resident physicians, who rotate to new hospitals and new attending physicians every few months, ours are on the same team constantly, year after year, in close communication with the physicians at all times.

Why should I choose to have surgery here?
The Institute for Joint Restoration was founded on a commitment to provide state-of-the art joint replacement with individual and compassionate patient care. We specialize in primary hip and knee surgery, along with complex revision surgery. This is all we do, and our outcomes are unmatched. Ours was the top rated joint replacement program in California by Healthgrades in 2011 and has continually received the highest marks for nearly two decades. If you live outside the area, you will be one of the 85% of our patients who travel here to participate in our program.

What should I expect after surgery?
After the operation is complete, our patients generally spend 2 – 3 hours in the recovery room. Hip replacement patients usually have the epidural removed just prior to leaving the recovery room. If an epidural was used, the patient is awake and comfortable during this interval.

Our patients are transported to the Center for Joint Replacement (CJR) building, where care is transferred to the staff of the Institute for Joint Restoration. We believe that separating our patients away from the ill patients in the main hospital is important for infection control. The private rooms on the unit add privacy that our patients have come to appreciate.

Hip patients can expect to be up walking with our Physical Therapists the day of surgery and generally require only an overnight hospital stay. Some important stretching exercises will be emphasized, as well as techniques for doing routine tasks independently.

Our single knee patients have a similar course as our hip patients, up and walking the same day and generally ready for discharge the next day. Patients recovering from partial knee replacement are also mobilized on the day of surgery and generally are comfortable enough to be discharged the same day. Our bilateral knee patients may keep their epidural catheters overnight and often require two nights in the hospital before meeting our discharge criteria.

Will I go home or to rehab after surgery?
Over 95% of patients are discharged directly home from the Institute. Homeward-bound patients are safe, comfortable and walking. Availability of family or friends to help with food preparation or household chores is beneficial for the first few days after discharge, especially. In the infrequent situations where safety is an issue or help is not available, our case manager specializes in facilitating brief rehab stays. In general, skilled nursing facilities should be avoided because of the risk of antibiotic-resistant bacteria known to colonize long-term residents at these facilities.

Will I need home medical or assistive equipment?
Yes. Many of our patients are discharged using a cane for assistance and some need a walker or crutches. For hip replacement patients, other special equipment is helpful for dressing and reaching items on the floor. Raised toilet seats are a nice convenience. Knee replacement patients may find cooling units can be very helpful to reduce knee swelling. All equipment will be provided by the Institute therapy staff, and most of it is covered by insurance.

What is the follow-up after surgery?
Patients return to clinic for the first postoperative visit about 2 weeks after surgery. Xrays are taken at this time and an evaluation performed. A second postoperative visit is scheduled for 4 weeks later for hip patients and knee patients whose range-of-motion is progressing slower than expected. Subsequent visits often occur three or 6 months after surgery, as needed. Patients then return on an annual or every two-year schedule.

Will I need physical therapy or an exercise program?
Yes. The therapy begins in the hospital and will continue at home. The Institute physical therapists will highlight the specific exercises to focus on from the education binder. A physical therapist visits our patients at home to ensure optimal continuity. Our knee patients generally need formal physical therapy in an outpatient clinic near their home as well, which we help facilitate. In some ways, what our patients gain from their successful surgeries is heavily influenced by what they put in, especially with regard to preoperative physical preparation and consistent, appropriate postoperative exercise.

When can I resume regular activity?
Most patients are able to walk without assistive devices by 2 -3 weeks, which means that balance has been restored and hands are freed to be useful. At the 6-week point, patients are able to resume regular activities, including golf. Tennis players will need to wait 3 months to begin hitting from a ball machine or simple volleying. Skiing will require 4 – 6 months.

How long does a joint replacement last?
In general, the need to redo a hip or knee replacement occurs at a rate of less than 1% per year. Implants can fail due to wear or loosening from the bone. Replacements that are done well, using modern materials, should last over 20 years in most patients. The implant failure rate depends on patient activity, age, weight, and patient characteristics (such as bone quality, muscle and ligament strength, and others). The plastic liners are highly durable, but if wear occurs, they can be removed and changed without disturbing the metal components. If necessary, one or both sides of a joint replacement can be replaced.

Will my insurance cover my surgery?
Medicare pays for joint replacement surgery and currently does not ration care. We are able to work with most private insurers and we do our best to provide care to those who choose our program. Due to the variability of insurance plans, it is difficult to predict what or how much will be covered by individual carriers. It may be useful to contact your insurance provider or your employer’s insurance liaison with questions.
Our business office would be happy to help you determine the likely out of pocket costs.
