To examine patient demographic and clinical outcomes associated with partial articular distal femoral fractures.
An IRB-approved study was conducted on a consecutive series of patients being treated for isolated partial articular distal femoral fractures at a single academic medical center between August, 2011 and July, 2023. Patient demographics, hospital quality measures and outcomes for each patient were reviewed. All fractures were fixed using screws alone or plate and screw constructs. Fractures were grouped into isolated entire medial or lateral condyle (OTA/AO 33B1 or B2) and posterior unicondylar (Hoffa) fractures (OTA/AO 33B3.2). Cohorts were compared for clinical, radiographic and complication outcomes using Chi-Square Tests and ANOVA tests.
A total of 30 patients were identified with a mean of 55.2 years. There were 16 (53.3%) isolated medial/lateral condylar fractures and 14 (46.7%) Hoffa fractures. There were no differences between the two fracture types in terms of baseline demographics. There was no difference in terms of length of stay or in-hospital complications between the fracture types. All fractures united. There was also no difference in range of knee motion at latest follow-up visit. Hoffa fractures required a longer time for radiographic healing (4.5 months vs. 3.05 months, p = 0.012).
Hoffa fractures require longer time to radiographic healing compared to other partial articular distal femoral fractures; however no other differences were seen based on fracture patterns.

研究与部分关节面股骨远端骨折相关的患者人口统计学特征和临床结局。
在2011年8月至2023年7月期间，在一家学术医疗中心对连续一系列接受孤立性部分关节面股骨远端骨折治疗的患者进行了一项经机构审查委员会批准的研究。回顾了每位患者的人口统计学特征、医院质量指标和结局。所有骨折均单独使用螺钉或采用钢板螺钉结构进行固定。骨折分为孤立的整个内侧或外侧髁（OTA/AO 33B1或B2）骨折和后单髁（Hoffa）骨折（OTA/AO 33B3.2）。使用卡方检验和方差分析对各队列的临床、影像学和并发症结局进行比较。
共纳入30例患者，平均年龄55.2岁。其中孤立性内侧/外侧髁骨折16例（53.3%），Hoffa骨折14例（46.7%）。两种骨折类型在基线人口统计学特征方面无差异。骨折类型之间在住院时间或院内并发症方面无差异。所有骨折均愈合。在最近一次随访时膝关节活动范围方面也无差异。Hoffa骨折达到影像学愈合所需时间更长（4.5个月对3.05个月，p = 0.012）。
与其他部分关节面股骨远端骨折相比，Hoffa骨折达到影像学愈合所需时间更长；然而，基于骨折类型未发现其他差异。
