Benchmark - A “Benchmark” is an agreed standard which can be applied to implant performance. It will usually be determined by using worldwide, outcome data. It usually infers the use of the non inferiority concept; ie, to achieve a benchmark the data on an implant must meet the standard that is required.

Kaplan Meier -The Kaplan-Meier method (Kaplan & Meier, 1958), also known as the "product-limit method", is a nonparametric method used to estimate the probability of survival past given time points. It is the most commonly used method of assessing survivorship of joint replacements and many other technologies
Linkability - % (Percentage). (Registry) The percentage of patients whose revision can be linked to a primary procedure in a registry. Essential if revision rates can be believed
Legacy Device - this is considered to include all devices previously certified under the European Medical Devices Directive 93/42/EEC (MDD) or Active Implantable Medical Devices Directive 90/385/EEC (AIMDD)

Predicate - This term is used extensively in the USA. A predicate device is one which has all or many of the features of the device in question but backing clinical data is not implied.
PSUR - Periodic Safety Update Reports
PTIR - “Prosthesis Time Incident Rate” is an index that can be used to measure the performance of an implant. The PTIR is the number of revisions divided by the total length of time the patients are at risk of revision. This is calculated with 95% confidence intervals (assuming a Poisson distribution). It is then compared with the overall PTIR for all implants of that type. To ensure that high-volume implants do not distort the overall results, if an implant constitutes more than 25% of the total number of primary procedures for that type, the overall PTIR is calculated both with and without that implant for comparison purposes.
SCCL - Supply Chain Co-ordination Limited
TAR - Total Ankle Replacement
TER - Total Elbow Replacement
THR - Total Hip Replacement
TKR - Total Knee Replacement
TSR - Total Shoulder Replacement (usually including hemiarthroplasties)
