Small-incision total hip arthroplasty (THA) has been shown to be safe and effective in achieving early postoperative improvements in pain and function. The comparative published reports of the two-incision, anterior, and mini-posterior techniques have defined indications for small-incision THAs. The mini-posterior approach appears to be better than the traditional posterior approach for THA in terms of early patient function and acceptance. There may be little difference among the mini-incision techniques when preoperative patient education and postoperative rehabilitation are equivalent. Correct component positioning has been consistently achieved with small-incision procedures, and short-term results are the same as those of traditional THA. The mini-posterior approach also has been shown to have psychological advantages because it allows patients to be more confident about their outcomes. New anesthesia and pain management techniques have also improved early functional results. With time and technical advances such as computer navigation, the use of minimally invasive THA will become more prevalent.
小切口全髋关节置换术（THA）已被证明在实现术后早期疼痛和功能改善方面是安全有效的。关于双切口、前路和微创后外侧技术的比较性已发表报告明确了小切口THA的适应症。就患者早期功能和接受度而言，微创后外侧入路在THA中似乎优于传统后外侧入路。当术前患者教育和术后康复相当时，微创技术之间可能差异不大。小切口手术始终能实现假体组件的正确定位，短期结果与传统THA相同。微创后外侧入路还被证明具有心理优势，因为它能让患者对其手术效果更有信心。新的麻醉和疼痛管理技术也改善了早期功能结果。随着时间推移以及计算机导航等技术进步，微创THA的应用将变得更加普遍。
