简要总结
The primary objective of this study is to compare postoperative muscle alterations between the minimally invasive direct anterior approach (DAA) and the minimally invasive direct lateral approach (DLA) in patients undergoing primary uncemented total hip arthroplasty, as assessed by magnetic resonance imaging at 12 months. Secondary objectives are to compare the trajectory of functional recovery and health-related quality of life between the two surgical approaches at 1, 3, 6, and 12 months postoperatively.

研究组 & 干预措施
MIS Direct Anterior Approach (DAA)
Primary uncemented total hip arthroplasty performed using a minimally invasive direct anterior approach
干预措施: Primary uncemented total hip arthroplasty performed using a minimally invasive direct anterior approach
Minimally Invasive Direct Lateral Approach (DLA)
Primary uncemented total hip arthroplasty performed via a minimally invasive direct lateral approach with partial gluteus medius detachment using the same implant system and perioperative protocol as the DAA group.
