Abstract：
BACKGROUND: The objective of this study was to compare the clinical outcomes of two internal fixation methods for high tibial osteotomy (HTO): double-triangle locking compression plate (DT-LCP) and T-shaped locking compression plate (T-LCP).
METHODS: 202 adult patients in our hospital between January 2018 and December 2021 were included and followed up for at least one year: group 1(DT-LCP, 98 patients) and group 2 (T-LCP, 104 patients). Detailed information on demographics, preoperative and postoperative follow-up, surgical procedures, and complications were collected. The information of the International Knee Documentation Committee Knee Evaluation Form (IKDC), Knee Injury and Osteoarthritis Outcome Score (KOOS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were collected before surgery and at the last follow-up.
RESULTS: A total of 202 patients were included in the per-protocol analysis. No significant difference was found in terms of demographic data between groups, except for age and BMI. Clinically relevant improvements in knee pain were reached up to last follow-up after the operation in both groups. The mean pain scores (KOOS, WOMAC) at the final follow-up were significantly higher among group 1 compared to group 2 (P = 0.040 and P = 0.023). Furthermore, the DT-LCP internal fixation exerted more excellent effects on other symptoms, function and quality of life than T-LCP internal fixation.
CONCLUSIONS: Our study demonstrated that DT-LCP provided better clinical performance due to its implant irritant pain, compared with T-LCP. Thus, DT-LCP is a feasible alternative for the fixation of OW-HTO.

摘要：
背景：本研究的目的是比较胫骨高位截骨术（HTO）两种内固定方法的临床效果：双三角形锁定加压钢板（DT-LCP）和T形锁定加压钢板（T-LCP）。
方法：纳入我院2018年1月至2021年12月的202例成年患者，并随访至少一年：第1组（DT-LCP，98例患者）和第2组（T-LCP，104名患者）。关于人口统计的详细信息，术前、术后随访,外科手术,收集并发症。国际膝关节文献委员会膝关节评估表（IKDC）的信息，膝关节损伤和骨关节炎结果评分（KOOS），在手术前和最后一次随访时收集西安大略省和麦克马斯特大学骨关节炎指数（WOMAC）。
结果：共202例患者纳入符合方案分析。在人口统计数据方面，组间没有发现显著差异，除了年龄和BMI。两组在手术后的最后一次随访中都达到了临床相关的膝关节疼痛改善。平均疼痛评分(KOOS，最终随访时，第1组的WOMAC）明显高于第2组（P=0.040和P=0.023）。此外，DT-LCP内固定对其他症状有更好的疗效，功能和生活质量优于T-LCP内固定。
结论：我们的研究表明，由于其植入物刺激性疼痛，DT-LCP提供了更好的临床表现，与T-LCP相比。因此，DT-LCP是固定OW-HTO的可行替代方案。
