Outcome

Type Measure Description Time frame Safety issue
Primary Knee society knee score a proven score for the measurement of knee function, the score ranges from 0 to 100, 100 being the best possible score, indicating normal knee function minimum 10 year follow up after the index surgery
Secondary WOMAC(Western Ontario and McMaster Universities) Scores A tool to evaluate patient function associated with knee. The WOMAC measures five items for pain (score range 0-20), two for stiffness (score range 0-8), and 17 for functional limitation (score range 0-68). The total score is summed from individual sections, and 0 is the best possible score. minimum 10 year follow up after the index surgery
Secondary Range of motion maximum flexion of the knee minimum 10 year follow up after the index surgery
