Severe osteoarthritis can be effectively treated with a total knee replacement (TKR), often referred to as an arthroplasty. Even though TKR patients have good survival rates, up to 20% of them are nevertheless unhappy. Current improvements in knee arthroplasty technology exhibit promise & may boost functional results. This study sought to present some unique TKR technologies, their current ideas, merits, & limitations. Whilst implant placement & limb positioning may be improved with patient-specific equipment, functional results are unchanged. The sensors must attempt to offer accurate data on equilibrium of ligaments during TKR. The accelerometers are sophisticated instruments created to enhance TKA positioning. However, their benefits remain still debatable. The robotic-assisted (RA) systems provide an exact & repeatable bone preparation owing to a robotic interface having a 3D surgical planning, based on preoperative 3D imaging or not. The new technologies in TKA are highly appealing & have continually progressed. Future orthopaedic technology will increasingly serve as a beneficial tool for surgeons performing patient-specific arthroplasty with patientspecific positioning goals.
