Why a joint replacement surgery is usually not performed in every hospital , this is because 

it's complications are truly harassing for both patient as well as for surgeons. 

 

The most common cause of TKR failure is infection .To avoid infection a centre must have a dedicated OR complex to be use only for joint replacement surgery. A very strict multilayer sterilization process from CSSD dept to OR complex. 

 

Why we say TKR protocol is strict because it starts from patient selection and goes upto month post surgery .

Any lecuna in this process be it patient selection or sterilization or post op rehabilitation then results will be surely compromised .

Responsibility of a successful result depend on both team and on patient.
