Given the contrapositive link between the posterior tibial plateau and the femoral condyle and the similar injury cause, the fracture type should be the same as the well-known Hoffa fracture of the femoral condyle. This study aims to report a case series with Hoffa-like tibial plateau fractures to improve understanding.
We analysed six consecutive patients presented with Hoffa-like tibial plateau fractures in our hospital between October 2014 and December 2020, a period in which 1924 tibial plateau fractures were treated. Patients' data on demographics, radiographs, surgical therapy, and assessment at a 12-month follow-up were retrieved.
The incidence of Hoffa-like tibial plateau fractures was 0.31% (6/1924). This study included three men and three women, with a mean age of 45.8 years. The injury mechanism was either a fall from a great height or a vehicle accident. On average, 7.5 days after the injury, patients were surgically treated with open reduction and internal fixation (ORIF) with place/screws via a lateral or posteromedial approach. At 10 to 15 weeks, all instances had osseous union on radiography. At 12-month follow-up, the HSS score of the operated knee ranged from 93 to 98 points (mean: 94.8), and Rasmussen radiograph score was from 15 to 18 (mean: 15.8). There were no intra-operative or post-operative problems.
This Hoffa-like fracture of the tibial plateau is a rare condition; however, it can occur. Orthopaedic surgeons should pay attention to this neglected but actually familiar fracture type.
鉴于胫骨平台后髁与股骨髁之间存在逆命题关系，以及类似的损伤原因，骨折类型应与众所周知的股骨髁 Hoffa 骨折相同。本研究旨在报告一系列 Hoffa 样胫骨平台骨折病例，以提高认识。
我们分析了 2014 年 10 月至 2020 年 12 月期间我院收治的 6 例连续 Hoffa 样胫骨平台骨折患者，在此期间共治疗了 1924 例胫骨平台骨折患者。检索了患者的人口统计学、影像学、手术治疗和 12 个月随访评估数据。
Hoffa 样胫骨平台骨折的发生率为 0.31%（6/1924）。本研究包括 3 名男性和 3 名女性，平均年龄为 45.8 岁。损伤机制要么是从高处坠落，要么是车祸。受伤后平均 7.5 天，患者通过外侧或后内侧入路行切开复位内固定（ORIF），使用钢板/螺钉固定。10 至 15 周时，所有患者的影像学均可见骨愈合。12 个月随访时，手术膝关节的 HSS 评分范围为 93 至 98 分（平均 94.8），Rasmussen 影像学评分为 15 至 18 分（平均 15.8）。无术中或术后并发症。
这种胫骨平台 Hoffa 样骨折较为罕见，但确实存在。骨科医生应注意这种被忽视但实际上较为熟悉的骨折类型。
