A previous randomized clinical trial at our institution demonstrated slower recovery of 35 2-incision total hip arthroplasties (THAs) when compared with 36 mini-posterior THAs at 2 years. The primary aim of the present study was to report concise 10-year follow-up results.
We retrospectively reviewed the 71 patients in the previous randomized clinical trial, comparing clinical outcomes, revisions, reoperations, and implant survivorship between the 2-incision and the mini-posterior THAs.
At the most recent follow-up, the mean Harris hip score was 85 in the 2-incision group and 87 in the mini-posterior group (P = .4). There were 4 revisions and 2 reoperations (16%) in the 2-incision group vs 1 revision and 3 reoperations (11%) in the mini-posterior group (P = .5). Ten-year survivorship free of aseptic revision or reoperation was 77% in the 2-incision group vs 90% in the mini-posterior group (P = .15).
There were no improvements in early or midterm clinical outcomes with the 2-incision technique. However, there was a clinical trend toward a higher rate of aseptic revisions in the 2-incision THA group.
我们机构之前的一项随机临床试验表明，与36例小切口后路全髋关节置换术（THA）相比，35例双切口全髋关节置换术在2年时恢复较慢。本研究的主要目的是报告简明的10年随访结果。
我们回顾性分析了之前随机临床试验中的71例患者，比较了双切口和小切口后路THA之间的临床结果、翻修、再次手术和植入物生存率。
在最近的随访中，双切口组的平均Harris髋关节评分是85分，小切口后路组是87分（P = 0.4）。双切口组有4例翻修和2例再次手术（16%），小切口后路组有1例翻修和3例再次手术（11%）（P = 0.5）。双切口组10年无无菌性翻修或再次手术的生存率为77%，小切口后路组为90%（P = 0.15）。
双切口技术在早期或中期临床结果方面没有改善。然而，双切口THA组无菌性翻修率有升高的临床趋势。
