Changes From Baseline in Patients' Function. Clinical Evaluation Using the Harris Hip Score
기간: 6 weeks, 6 months, 1 year
|
The items in the Harris hip score (HHS) include an analysis of the operated hip according to pain, function, mobility and stability, and an analysis of deformities, in a scale form 0 point (the worst condition) to 100 points (the best condition). The Harris Hip Score will be used to assess the subjective and objective improvement in the patient. The usefulness of the score has been designed to estimate clinical outcomes after THA and demonstrated high reliability and validity. The HHS values at each time points, 6 weeks, 6 months and 1 year, and for each patient, will be reported as difference respect the preoperative value collected at preoperative. |

Changes From Baseline in Patient's Activity Level. Assessment Using the High Activity Arthroplasty Score.
기간: 6 months, 1 year
|
The HAAS was designed to detect subtle variations in functional ability after lower limb arthroplasty, in a scale from 0 (minimum, the worst condition) to 18 points (maximum, the best condition) The HAAS values at each time points, 6 months and 1 year, and for each patient, will be reported as difference respect the preoperative value collected at preoperative.

Radiological Evaluation to Assess the Fixation and Stability of Femoral and Acetabular Components.
기간: 6 months, 1 year
|
Stability and fixation of both, femoral and acetabular component will be assessed counted number of events of stem subsidence, femoral and cup loosening, cup migration and presence of radiolucencies occurred during the study at 6 months and 1 year time points.
