Total Knee Replacement

Total knee replacement is an operation performed by general orthopaedic surgeons and subspecialists alike and, although generally successful, the levels of patient satisfaction after TKR have not paralleled those of patients undergoing total hip replacement surgery. A plethora of reasons, acting alone or in concert, have been cited as leading to inferior outcomes, or even frank early failure, after TKR surgery. Recently, patient-specific instrumentation (PSI) has been introduced in TKR surgery. These instruments are jigs manufactured on a case-by-case basis and designed to fit precisely on the tibia and femur in preparation of the bone cuts during surgery. The principal purported advantages of this new technology are an increased accuracy of bone cuts, and consequently positioning of the implants, coupled with decreased operative time. Despite their increased cost, customised cutting jigs are currently “in vogue” in many parts of the world.
