BACKGROUND:Studies have shown that anterolateral approach for repairing the hip joint capsule has great effects on dislocation after hip replacement, but it remains unclear at present. OBJECTIVE: To study the impact of anterolateral approach for repairing the hip joint capsule on dislocation after artificial hip joint replacement. METHODS: 480 patients, who received artificial hip joint replacement in the First People’s Hospital of Qinzhou from January 2010 to January 2014, were enroled in this study. They were divided into the control group (January 2010 to January 2012) and the observation group (February 2012 to January 2014) according to the order of their admission, each of 240 cases. The control group was subdivided into the total hip replacement group (A1 group) and the femoral head replacement group (A2 group), each of 120 cases; and the observation group was also subdivided into the total hip replacement group (B1group) and the femoral head replacement group (B2 group), each of 120 cases. A1group and A2 group were subjected to artificial hip joint replacementvia anterolateral approach. B1 group and B2 group were subjected to artificial hip joint replacementvia anterolateral approach and the repair of the joint capsule. The postoperative early dislocation rate was analyzed in patients of A1 group and B1 group. Postoperative early dislocation rate was analyzed in patients of A2 group and B2 group. RESULTS AND CONCLUSION: The rate of early postoperative dislocation was 6.7% in A1 group, and 0.8% in the B1 group. The rate of early postoperative dislocation was significantly higher in the A1group than in the B1 group (P < 0.05). The rate of early postoperative dislocation was 3.3% in the A2 group and 0.8% in the B2 group. No significant difference was found between the A2 and B2 groups (P > 0.05). Results showed that anterolateral approach in repairing the hip joint capsule can effectively reduce the incidence of postoperative dislocation after the total hip replacement, but does not obviously impact postoperative dislocation.%背景：研究指出，前外侧入路修复髋关节囊对人工髋关节置换后脱位有很大的影响，但目前尚未明确。目的：观察前外侧入路修复髋关节囊对人工髋关节置换后脱位的影响。方法：选取广西钦州市第一人民医院2010年1月至2014年1月接诊并进行人工髋关节置换的480例患者作为研究对象，按照入院顺序分为对照组(2010年1月至2012年1月)和观察组(2012年2月至2014年1月)，各240例。对照组细分为全髋关节置换组(A1组)和人工股骨头置换组(A2组)，各120例；观察组也细分为全髋关节置换组(B1组)和人工股骨头置换组(B2组)，各120例。A1组和A2组采用前外侧入路行人工髋关节置换；而B1组和B2组采用前外侧入路行人工髋关节置换并修复关节囊。分别对比分析A1组患者和B1组患者置换后早期脱位率，以及A2组患者和B2组患者置换后早期脱位率。结果与结论：A1组患者置换后早期脱位率为6.7%，而 B1组患者仅为0.8%，A1组患者的置换后早期脱位率明显高于B1组(P <0.05)。A2组患者置换后早期脱位率为3.3%，而B2组患者仅为0.8%，但两组差异无显著性意义(P >0.05)。提示前外侧入路修复髋关节囊可以有效降低人工全髋关节置换后脱位的发生率，但是对人工股骨头置换后脱位无明显影响。
