About Knee Arthoplasty
One of the most common surgical procedures that has become increasingly more efficient is knee arthoplasty, or a knee replacement surgery. Originally designed to decrease the difficulties of osteoarthritis as well as the various troubles associated with knee injuries and subsequent recovery time, knee arthoplasty can now be performed on various forms of more severe arthritis, such as psoriatic arthritis or rheumatoid arthritis. Doctors more commonly perform various versions of knee arthoplasty due to patients experiencing pain and chronic discomfort from cartilage defects, ligament tears, and meniscus tears.
The numerous benefits of knee arthoplasty include increased ability of knee usage and increased vitality and energy because the knee no longer causes extreme pain or strain. A knee arthoplasty can either be a partial or total replacement, and with contemporary techniques, patients can often begin physical therapy and rehabilitation less than a week after the surgery.
Knee Arthroplasty Procedure
The actual process of knee arthoplasty involves removal of the problem areas within the knee, which can only be reached by the removal of the vastus medialis, or quadriceps muscle, from the patella, or knee bone. The ends of the femur and shaped to achieve the most optimal connection. The trouble cartilage and anterior cruciate ligament are then removed, and the implant to replace or partially replace the patella is inserted. The implant is usually made of polyethylene or metal. Patients undergoing knee arthroplasty will typically not experience pain during surgery because of general anesthesia administered to alleviate any discomfort or pain while the surgery is being performed.
The purpose of physical rehabilitation is to ensure that the knee does not freeze up or cause walking and movement problems. Often, physical therapy also involves various assistance devices such as canes and crutches, which are designed to allow patients to be up and moving as soon as possible. Most patients who properly follow procedure can expect to be mobile again within six weeks.
Knee Arthroplasty Risks
It is important for patients to understand that knee arthoplasty is a major surgery, and that preparation and recovery time should be considered in this context. The surgery can sometimes increase in complications when arthritis is more advanced, requiring more time in actual surgery. Often, it is essential to undergo pre-operative tests, such as electrolyte measurement that and those that predict the risks of post-operative blood clotting. It is most effective to undergo pre-op work at the hospital before the surgery, as this makes the proper preparations for surgery considerably easier.
Knee Arthoplasty Surgery Abroad
As a major surgery, the cost of arthoplasty can be quite high in countries in North America and Europe. Many people are choosing to have their surgeries in low-cost, high-skilled countries like South Africa and Thailand. Hospitals in these countries often have package deals for medical tourists that include plane tickets, 5-star recovery rooms, pre- and post-surgery work, all at a cost that is less than having arthoplasty at home.
