For the last 4 years, total knee replacement has been the go-to surgical solution for those suffering from end-stage knee arthritis (wearing of knee). Despite being well-established and having a success rate of 85-92%, Conventional Total Knee Replacement (TKR) is associated with a small percentage of unsatisfactory results. Conventional TKR used metal implants on a plastic (polyethylene) spacers and causes loosening of joints due to relatively higher wear & tear while these metal implants rub against the polyethylene spacer. Moreover, hypersensitive reactions to metal are possible in a small percentage of patients (2 to 3%) which causes allergic reactions, mimicking infections and causing loosening of implants. These reasons require revision surgery to be done.
Ceramic Total Knee Replacement comes as a shot in the arm for younger patients who are suffering from end-stage knee arthritis because of the key advantages ceramic implants offer. Ceramic TKR uses Ceramic implants moving against plastic (polyethylene) spacers leading to the various benefits.
Ceramic implants offer minimal wear & tear, high resistance to scratching, longer life and are less likely to react with body and cause unwanted reactions (more biocompatible). For all these reasons, ceramic TKR offers longer life of implants and enables the patient to engage in more strenuous and intensive activities.
While conventional metal implants are expected to last anywhere between 20 to 25 years, ceramic implants are expected to last between 45 and 50 years. The success rate of this procedure is more than 95%. These factors make it extremely suitable for younger patients with knee arthritis and gives them back their mobility, relieves pain and offers more comfort and a good quality of life.
