Hi David,


TKR (total knee replacement) or also known as total knee arthroplasty is a medical procedure performed after initial medical treatment such as administration of drugs or physiotherapy does not help reduce complaints related to inflammation or damage to the knee joint.


Nowadays implants used in TKR are quite varied but are generally distinguished from metal (a mixture of cobalt-chrome and titanium) or non-metal such as ceramics, in the middle (between 2 joints) given plastic spacers as joint bearings.


So far the FDA has not approved the use of ceramics as an implant material. Research so far only shows that ceramic material has a lower wear rate than metal and can be used if it has special conditions such as metal allergies. The use of ceramics might be more common in a few years if the information obtained from the results of studies is more sufficient.


CAS or computer assisted navigation system shows better results in positioning the prosthesis (implant). However, there is no evidence that shows whether this is beneficial for patients in functioning prostheses so that conclusions cannot be drawn.


I cannot provide appropriate information regarding the cost of the difference between one TKR procedure and another because it really depends on the type, procedure, place where you performed the operation and the condition of someone who performed the operation. Due to the condition and needs of a person can be very varied compared to others so to get the appropriate information about prognosis (predictions related to the procedure) should be asked directly with the doctor who treats you to get a picture that suits your condition.


May be useful,
