Clinical Trial Summary

This clinical study has the aim to evaluate clinical, radiographic, patient-reported outcomes of total hip arthroplasty with the implant of Mueller cemented acetabular cups up to 2 years after surgery, in order to assess the performance of the device. Furthermore, it aims to collect short-term survivorship of the implant and the incidence of early complications.

• Patient with advanced articular destruction generated by primary degenerative or post-traumatic arthrosis or rheumatoid arthritis;
• Patient with avascular necrosis of the femoral head or fracture of the femoral neck;
• Patient with congenital or acquired deformity;
• Patient with failures of previous operations, like osteosynthesis, articular reconstruction, arthrodesis, hemi-arthroplasty or total arthroplasty.

3. The patient is willing and able to complete scheduled follow-up evaluations as described in the Patient Information Sheet; Exclusion Criteria: The patient should be excluded from the study if he/she meets any of the following

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Clinical progression of Harris Hip Score (HHS) from baseline to 2 years after surgery	HHS ranges from 0 to 100, being 0 the worst and 100 the best conditions. HHS is reported as 90-100 for excellent results, 80-90 for good, 70-79 for fair, 60-69 for poor, and below 60 for a failed result. The outcome is considered satisfactory for values over 80	2 years Follow up
Secondary	Radiographic evaluation and stability assessment of the implant up to 2 years FU	Radiographic stability, radiographically detectable complications	6 weeks, 1 year and 2 years FU
Secondary	Clinical progression of HOOS up to 2 years FU, compared to the baseline	Hip disability and osteoarthritis outcome score (HOOS) is a patient-reported outcome measurement, that ranges from 0 to 100, with 100 indicating no symptoms and 0 indicating extreme symptoms	6 weeks, 1 year and 2 years FU
Secondary	Change in TUG from preoperative up to 2 years FU	Timed Up and Go	6 weeks, 1 year and 2 years FU
Secondary	Clinical progression of HHS up to 1 year FU, compared to the baseline	Harris Hip Score	6 weeks, 1 year
Secondary	Implant survivorship (Kaplan-Meier estimate) at 2 years after surgery		2 years FU
Secondary	Incidence of device-related AE/SAE up to 2 years of follow-up	Adverse events and device deficiencies	6 weeks, 1 year and 2 years FU
