About this study
Official title: Comparative 3D Gait Analysis: Impact of Total Hip Arthroplasty Stem Anchoring (Metadiaphyseal vs Metaphyseal)
Patients with hip osteoarthritis who were indicated for total hip arthroplasty were prospectively enrolled and randomized to receive either a short (metaphyseal) stem or a conventional (metadiaphyseal) stem hip arthroplasty. Three-dimensional gait analysis was performed regularly (preoperatively and at multiple postoperative time points) to determine whether conservative implants result in superior objective and patient-reported outcomes

Conventional (metadiaphyseal) stem Total Hip Arthroplasty
| Study group | Role | What they receive |
|---|---|---|
| Conservative (metaphyseal) stem hip arthroplasty | Active comparator | Hip arthroplasty is performed through a minimally invasive anterolateral hip approach. All replacements are completely non-cemented, articulations include polyethylene or ceramic inserts on ceramic heads. Cups are standardly fixed through press-fit principle, no additional pelvis screws were standardly used. Special curved femoral reamers are used in order to consume as little bone stock as possible (only the metaphysis) and provide a muscle-sparing approach. Receives: Procedure: Conservative Total Hip Arthroplasty |
| Conventional (metadiaphyseal) stem hip arthroplasty | Active comparator | Hip arthroplasty is performed through a minimally invasive anterolateral hip approach. All replacements are completely non-cemented, articulations include polyethylene or ceramic inserts on ceramic heads. Cups are standardly fixed through press-fit principle, no additional pelvis screws were standardly used. Standard femoral preparation is performed with prosthesis taking bone stock from the metadiaphyseal area of proximal femur, however, gluteal insertions were preserved in simillar fashion as in metaphyseal implants. Receives: Procedure: Conventional Total Hip Arthroplasty |
What is being measured
The primary outcome is the main question the study is designed to answer.
3D Gait analysis - Gait Profile Score
The Gait Profile Score (GPS) is a numerical index (range 0-10, the lesser the number, the better for the patient). The GPS comprises of the kinematic parameteres that are also called the Gait Variable Scores (hip flexion, rotation and abduction) and the spatiotemporal parameters (step time, step length and step cadence). All of these parameters are also mentioned ad separate outcome measures. The extraction of GPS from the 2 basic data groups was done automaticaly through specialised software which is based on the work of Baker et al. (Baker R, McGinley JL, Schwartz MH, et al. The gait profile score and movement analysis profile. Gait Posture. 2009;30(3):265-269. doi:10.1016/j.gaitpost.2009.05.020).
Measured: from preoperative to 1 year postoperative
Secondary outcomes (1)
The Modified Harris Hip Score
Total range of the questionnaire is 0-100 points, more points=better patient reported outcome. 90-100 points = excellent result; 80-89 = good result; 70-79 = fair result; < 70 points = poor result.
Measured: from preoperative to 1 year postoperative

What does the primary outcome measure?
3D Gait analysis - Gait Profile Score (time frame: from preoperative to 1 year postoperative). It is what the study was designed to measure, not a finding.
