The benefits of different surgical approaches for total hip arthroplasty continue to be debated. One hundred patients were prospectively enrolled and randomized into 2 groups. One group underwent total hip arthroplasty through a single-incision modified Smith-Peterson approach, whereas the other group underwent total hip arthroplasty through a direct lateral approach. All patients received the same postoperative protocol. Evaluation included operative time, estimated blood loss, analgesia requirement, transfusions, and length of stay. Functional outcome was assessed preoperatively and postoperatively. Up to 1-year follow-up, the direct anterior group demonstrated significantly better improvement in both the mental and physical health dimensions of Short Form-36 and Western Ontario McMaster Osteoarthritis Index compared with direct lateral approach group. At 2 years, the results in both groups were the same.
不同全髋关节置换术入路的优势仍存在争议。本研究前瞻性纳入 100 例患者并随机分为两组。一组采用单一切口改良 Smith-Peterson 入路行全髋关节置换术，另一组采用直接外侧入路行全髋关节置换术。所有患者均接受相同的术后方案。评估包括手术时间、估计失血量、镇痛需求、输血和住院时间。术前和术后均进行功能结局评估。随访至 1 年时，直接前侧组在 Short Form-36 量表的精神健康和躯体健康维度以及 Western Ontario McMaster Osteoarthritis Index 评分方面的改善明显优于直接外侧组。在 2 年时，两组的结果相同。
