简要总结
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

研究组 & 干预措施
Conservative (metaphyseal) stem hip arthroplasty
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.

Conventional (metadiaphyseal) stem hip arthroplasty
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.

结局指标
主要结局
3D Gait analysis - Gait Profile Score
时间窗: from preoperative to 1 year postoperative
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).
