Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Survival Rate	Evaluation of the survival rate for Insignia Hip Stem is defined as absence of femoral stem revision for aseptic loosening or device-related femoral fracture.	10 years
Primary	Harris Hip Score (HHS)	The Harris Hip Score (HHS) assesses pain, function, joint deformity and range of motion.; Scores can range from 0 to 100 with 0 being the worst and 100 being the best score.; A score of 80-100 is considered good-excellent and a score of less than or equal to 79 is considered fair-poor. 90-100 = excellent 80-89 = good 70-79 = fair 0-69 = poor	10 Years
Secondary	Harris Hip Score (HHS)	The Harris Hip Score (HHS) assesses pain, function, joint deformity and range of motion.; Scores can range from 0 to 100 with 0 being the worst and 100 being the best score.; A score of 80-100 is considered good-excellent and a score of less than or equal to 79 is considered fair-poor. 90-100 = excellent 80-89 = good 70-79 = fair 0-69 = poor	pre-op, 6 week, 1,2,5 and 7 years
Secondary	EQ-5D - Descriptive System	The EuroQol-5 Dimension (EQ-5D) is a subject-completed questionnaire designed to assess subject health state values.; The EQ-5D descriptive system comprises the following five dimensions: mobility self care, usual activities, pain/comfort and anxiety/depression. Each dimension has 3 levels indicating no problems, some problems or extreme problems. The index values on a scale between -1 (low) and 1 (high) are showing the average health status according to the 5 dimensions: A low score shows worse health and a high score shows better health.	pre-op, 6 week, 1,2,3, 4,5,7 and 10 years
Secondary	EQ-5D - Visual analogue scale (VAS)	The EuroQol-5 Dimension (EQ-5D) is a subject-completed questionnaire designed to assess subject health state values.; With the EQ Visual Analogue Scale (VAS) the respondents can report their perceived health status with a grade ranging from 0 (the worst possible health status) to 100 (the best possible health status).	pre-op, 6 week, 1,2,3, 4,5,7 and 10 years
Secondary	Survival Rate	Evaluation of the survival rate for Insignia™ Hip Stem is defined as absence of femoral stem revision for aseptic loosening or device-related femoral fracture; Success rate at two (2) years postoperative with the Insignia™ Hip Stem is not worse than 98 % with a non-inferiority margin of 3.5%.; Success rate at 10 years postoperative with the Insignia™ Hip Stem is not worse than 95% with a non-inferiority margin of 5%.	2 years
