Primary | Harris Hip Score - Functional change between preop and 3 years FU | Functional change in Harris Hip Score (HHS) from preoperative (baseline) to 3 years after surgery.
The maximum score of HHS is 100 points. Pain domain contributes 44 points, function 47, ROM 5 and absence of deformity 4 points. Results can be interpreted with the following: Less than 60= failed result; 60 to 69= poor result; 70 to 79= fair; 80 to 90= good; 90 to 100= excellent; |
3 years | |
Secondary | Harris Hip Score - Functional change between preop and 6 weeks FU, 3 months FU, 1 year FU | Functional change in Harris Hip Score between preoperative (baseline) and 6 weeks FU, 3 months FU, 1 year FU; | 6 weeks, 3 months, 1 year | |
Secondary | Oxford Hip Score - Functional change between preop and 6 weeks FU, 3 months FU, 1 year FU, 3 years FU | Functional change in Oxford Hip Score between preoperative (baseline) and 6 weeks FU, 3 months FU, 1 year FU, 3 years FU. The OHS is a short 12-item survey. It comprises two domains (pain and function), with six items or questions in each, using the following scoring: each question has been scored between 0 and 4, with 4 being the best outcome, producing overall scores running from 0 to 48, with 48 being the best outcome.
The calculation of the total score of OHS is based on this scoring system and the resulted score can be interpreted as follows: less than 27 points= poor; 27 to 33 points= fair; 34 to 41 points= good; 41 to 48 points= excellent |
6 weeks, 3 months, 1 year, 3 years | |
Secondary | VAS satisfaction | Functional evaluation of VAS satisfaction at 6 weeks FU, 3 months FU, 1 year FU, 3 years FU;
Patient is asked to rate his satisfaction by making a vertical mark on the 100-mm line. The measurement in millimetres is eventually converted to the same number of points ranging from 0 to 100 points |
6 weeks, 3 months, 1 year, 3 years | |
Secondary | Radiographic implant evaluation and stability assessment of Logica Mirror stem | Stability assessment of Logica Mirror stem (through radiographic implant evaluation) at the following timepoints: at discharge, 6 weeks, 3 months, 1 year, 3 years.
For assessing the stability of the femoral component in a cemented configuration, the presence of radiolucent lines should be recorded both at stem-cement interface and at cement-bone interface. At each postoperative time-point the radiolucencies will be measured in every Gruen zone and graded in accordance to the following classification: None: No evidence of radiolucency mm: Presence of 1 mm-width radiolucent lines mm: Presence of 2 mm-width radiolucent lines > 2 mm: Presence of radiolucent lines wider than 2 mm |
At discharge, 6 weeks, 3 months, 1 year, 3 years | |
Secondary | Survival rate of the implant at 3 years after surgery | Survival rate of the implant (Kaplan-Meier) at 3 years after surgery | 3 years | |
Secondary | Safety profile of Logica Mirror by recording adverse events (AE), serious adverse events (SAE), device deficiency (DD), adverse device effect (ADE), serious adverse device effect (SADE) | Incidence of device-related adverse events( AE), serious adverse events (SAE), device deficiency (DD), adverse device effect (ADE), serious adverse device effect (SADE) at every follow-up (intraoperative, immediate post-operative, 6 weeks, 3 months, 1 year, 3 years). | up to 3 years |
