TKA will be performed using the PS Bearing Design. The PS bearings are designed to provide ±1.5 degrees varus/valgus constraint and ± 5.5 degrees internal/external rotation constraint.

KOOS, JR contains 7 items from the original KOOS survey. Items are coded from 0 to 4, none to extreme respectively. KOOS, JR is scored by summing the raw response (range 0-28) and then converting it to an interval score. The interval score ranges from 0 to 100 where 0 represents total knee disability and 100 represents perfect knee health.

FJS is a patient-reported outcome measure intended to determine a patient's ability to "forget" about their affected joint after surgery or treatment. FJS consists of 12 questions - the total score range is 0-100. The higher the score, the less the patient is aware of their affected joint when performing daily activities.

The EQ-5D comprises five questions on mobility, self care, pain, usual activities, and psychological status with three possible answers for each item (1=no problem, 2=moderate problem, 3=severe problem. A summary index with a maximum score of 1 can be derived from these five dimensions by conversion with a table of scores. The maximum score of 1 indicates the best health state, by contrast with the scores of individual questions, where higher scores indicate more severe or frequent problems. In addition, there is a visual analogue scale (VAS) to indicate the general health status (0-100) with 100 indicating the best health status.
