Roughly 600,000 knee replacements are performed each year. All total knee replacements consist of a four-part system: a metal tibial component, a metal femoral component, a plastic insert between them, and a patellar component. A common issue with knee replacements is what surgeons refer to as “wear”.
As the surfaces of the implant rub together, tiny fragments of plastic and metal material wear off. Implant wear accounts for one reason why knee implants can fail, and why a patient may undergo repeat surgery years after the original procedure. One recent study found that in a group of knee implants that were “revised” after an average of 7 years of use, 44% of the cases were the result of plastic wear. There are potential risks with knee replacement surgery such as loosening, fracture, dislocation, wear and infection that may result in the need for additional surgery. Do not perform high impact activities such as running and jumping unless your surgeon tells you the bone has healed and these activities are acceptable. Early device failure, breakage or loosening may occur if you do not follow your surgeon’s limitations on activity level. Early failure can happen if you do not guard your knee joint from overloading due to activity level, failure to control body weight or accidents such as falls. Knee replacement surgery is intended to relieve knee pain and improve knee functions. Talk to your surgeon to determine what treatment may be best for you.
Total Hip Replacement Information
Over 200,000 hip replacements are performed each year in the United States. Hip replacement surgery is one of the most successful procedures in modern medicine. Patients are able to return to high level of function following the rehabilitation. It relieves the pain, increases leg strength, improves quality of life and provides years of easier movement.
BIRMINGHAM HIP™ Resurfacing System
An exciting new alternative to total hip replacement is now available in the United States. Used successfully for years around the globe, the BIRMINGHAM HIP™ Resurfacing System has recently been approved by the Food and Drug Administration for use in the United States. Now, patients suffering from hip pain due to arthritis, dysplasia or avascular necrosis can benefit from its conservative approach to treatment.
Because this technologically advanced surgical procedure resurfaces rather than replaces the end of your femur (thighbone), you may participate in more strenuous physical activity with an implant that is potentially more stable and longer-lasting than traditional total hip replacements. And if future revision surgery is required, it may be a less complex and less traumatic procedure.
In fact, a 1,626-hip study of the effectiveness of the technique found that 99.5-percent of patients responded they were “Pleased” or “Extremely pleased” with the results of their BIRMINGHAM HIP™ Resurfacing surgery.
