Knee Replacement Surgery - A Comprehensive Guide to Arthroplasty

Read a comprehensive guide on what to expect from Arthroplasty- A knee replacement surgery that removes damaged bone and debris from the knee joint.

Knee Replacement Surgery, also known as Arthroplasty, is done to provide relief from pain, joint damage and disease within the knee. When a surgeon performs a knee replacement, he or she cuts away damaged bone and cartilage from the bones in the thigh, shin and kneecap and replaces it with an artificial joint made of polymers, plastics and metal alloys which can be done in either a partial or full Knee Replacement.  Most people choose to undergo a Knee Replacement due to the disabling affects of Osteoarthritis, Rheumatoid Arthritis or Psoriatic Arthritis. Although some surgeries are required due to injuries to the knee such  tears in the Meniscus, Cartilage defects, and tears in the Ligament.

During a Knee Replacement Surgery, the knee is rested in a bent position so all the surfaces of the knee joint. are equally exposed. The surgeon will then make an 8 to 10 inch incision and will move the knee cap aside to gain access to the joint. He or she will then cut away any of the damaged bone or debris from tears to the cartilage. Once the debris is cleaned up, the surgeon will then adhere the new artificial joint or partial joint to the rest of the knee. Before stitching closed the incision, the surgeon will bend and rotate the new knee to be sure it works and fits properly in place. The average time it takes to perform a Knee Replacement Surgery is about two hours depending on how much damage has been done to the knee joint.

Patients who undergo a Knee Replacement are at risk similarly to any other Joint Replacement Surgery. The most common complications from the surgery tend to be infection, blood clots, fractures, instability, and loss of motion.

Recovering from surgery is a step by step process that often involves physical therapy of gradual degrees and may sometimes include the use of a walker or cane. An average recovery period in which a patient can return to full motion and movement with their knee takes about three months although some patients find that it takes much longer depending on how well they heal from the surgery. Some patients experience more scar tissue, stiffness and pain than others. it is also not uncommon for patients to experience some numbness which can be permanent as a result from the initial incision through the nerves surrounding the knee joint.

Some patients who intend to undergo the surgery may be required to lose weight, such as those who are morbidly obese, to encourage better success not only with the rehabilitation and recovery, but also to decrease complications during the surgery.

As with all surgeries, it is best to consult a physician to discuss further the risks, and complications associated with the use of anesthetics and products such as Latex that can cause an allergic reaction.
