Inclusion: * The patients enrolled in the study were already operated at the time of the screening. * All the patients with osteoarthritis of the hip who received CMK21 hip stem between 2005 and 2007. * Skeletally mature patients requiring primary total hip arthroplasty due to non-inflammatory arthritis (degenerative joint disease) such as osteoarthritis, avascular necrosis, or traumatic arthritis.

Design outcomes

Primary

MeasureTime frameDescription
Implant revision rate5 yearsListing of implant status at 5 years to analyse the survival rate
Device related adverse events10 yearsMedical chart will be reviewed and device related events collected to monitor the safety
Radiographic assessment5 and 10 YearsRadiolucent lines and radiosclerotic lines at both the bone cement and cement prosthesis interface

Secondary

MeasureTime frameDescription
Harris Hip Score (HHS)5 and 10 yearsHarris Hip Score is a clinical evaluation which consists of a maximum of 100 points (best possible outcome) covering pain (1 item, 44 points), function (7 items 47 points total), absence of deformity (1 item, 4 points), and range of motion (2 items, 5 points total).
EuroQoL Five Dimensions Questionnaire (EQ-5D)5 and 10 yearsThe EuroQoL Five Dimensions Questionnaire is a subject self-assessment of quality of life and consists of five questions covering the dimensions of mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. The EQ-5D questionnaire also includes a Visual Analog Scale (VAS), by which subjects can report their perceived health status with a grade ranging from 0 (the worst possible health status) to 100 (the best possible health status).
