Knee osteoarthritis has doubled in prevalence since the mid-20th century
The results from this study published in the Proceedings of the National Academy of Sciences of the United States of America contradict the view that the recent surge in knee osteoarthritis occurred simply because people live longer and are more commonly obese. Instead, this results highlight the need to study additional, likely preventable risk factors that have become ubiquitous within the last half-century

Revision total knee arthroplasty (TKA) is a complex procedure which carries both a greater risk for patients and greater cost for the treating hospital than does a primary TKA. As well as the increased cost of peri-operative investigations, blood transfusions, surgical instrumentation, implants and operating time, there is a well-documented increased length of stay which accounts for most of the actual costs associated with surgery.

From TGA Australia "LCS Complete RPS Knee System (used in knee replacements)" hazard alert
Hazard alert - higher than expected revision rate when used without patella resurfacing. Consumers and health professionals are advised that Johnson & Johnson Medical, in consultation with the TGA, has issued a hazard alert regarding its LCS Complete RPS Knee System due to a higher than expected revision rate when the patella is not resurfaced. Knee implants can be used in a variety of configurations. One option is to use a 'button' to 'resurface' the back of the patient's patella and keep it from potentially rubbing against the implant as the knee bends. An additional analysis of data derived from the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) 2014 Report shows that the revision rate for the LCS Complete RPS Knee System when used without a patella button is higher than the revision rate of other unresurfaced posterior-stabilised (PS) knee implants being used in Australia.
