Schatzker IV-VI tibial plateau fractures usually happen in the weight-bearing part of the knee joint. They are hard to fix with traditional methods because they damage soft tissues and make it hard to get back to normal activities. This study introduces a modified hockey-stick medial plate (mHSMP) designed to improve functional outcomes while reducing surgical complexity.
This retrospective study included 40 patients with Schatzker IV-VI tibial plateau fractures (20 in the experimental group treated with the mHSMP and 20 in the control group treated with a traditional medial plate) who were followed up for 12 months. Surgical time, intraoperative blood loss, fracture healing time, postoperative complications, and knee function, as assessed by the Hospital for Special Surgery (HSS) score, were compared between the two groups.
Compared with the control group, the experimental group had significantly greater HSS scores at 3 days postsurgery (50.2 ± 1.7 vs. 43.6 ± 1.8, P < 0.001), 3 months (68.2 ± 1.8 vs. 61.7 ± 1.9, P < 0.001), and 6 months (83.2 ± 1.9 vs. 76.7 ± 2.1, P < 0.001). No significant differences were observed between the two groups in terms of surgical time, intraoperative blood loss, fracture healing time, or postoperative complications.
Compared with traditional fixation methods, the mHSMP results in superior early functional recovery with comparable safety, providing an effective alternative for treating Schatzker IV-VI tibial plateau fractures.
Schatzker IV-VI型胫骨平台骨折通常发生在膝关节的负重部位。由于会损伤软组织且难以恢复正常活动，用传统方法固定这些骨折很困难。本研究介绍了一种改良的曲棍球棒形内侧钢板（mHSMP），旨在改善功能预后，同时降低手术复杂性。
这项回顾性研究纳入了40例Schatzker IV-VI型胫骨平台骨折患者（实验组20例采用mHSMP治疗，对照组20例采用传统内侧钢板治疗），随访12个月。比较两组的手术时间、术中失血量、骨折愈合时间、术后并发症以及由特种外科医院（HSS）评分评估的膝关节功能。
与对照组相比，实验组在术后3天（50.2±1.7对43.6±1.8，P<0.001）、3个月（68.2±1.8对61.7±1.9，P<0.001）和6个月（83.2±1.9对76.7±2.1，P<0.001）时的HSS评分显著更高。两组在手术时间、术中失血量、骨折愈合时间或术后并发症方面未观察到显著差异。
与传统固定方法相比，mHSMP在安全性相当的情况下能实现更好的早期功能恢复，为治疗Schatzker IV-VI型胫骨平台骨折提供了一种有效的替代方法。
