New report added

“The increased demand for international performance standards in total joint replacement emphasizes the need for a standardized global benchmarking system. Global benchmarking allows comparison of device performance at specific time points to a defined standard and to the performance of other equivalent devices. A global benchmarking system can enhance international public safety and cost effectiveness through the identification and subsequent use of higher performing arthroplasty prostheses.”
