We aimed to investigate the technical advantages and clinical outcomes of lateral unicompartmental knee arthroplasty (LUKA) through the medial parapatellar approach.
From August 2022 to June 2024, 104 patients who underwent LUKA via the medial parapatellar approach were enrolled. The operation time, hospital stays, surgical complications and follow-up period were collected. Pre- and postoperative Range of movement (ROM), Oxford knee score (OKS) and Hospital for special surgery knee score (HSS) were recorded and further investigated by paired-samples t-test analysis.
Primary demographic data of the retrospective case series collected include gender (30 males and 74 females), age (63.1 ± 8.37 years, range 49-84 years), operation time (86 ± 17 min, range 52-135 min), hospital stays (4.0 ± 1.1 days, range 3-8 days) and follow-up period (9.9 ± 5.7 months, range 1-23 months). There was a significant improvement in ROM (P < 0.001), OKS (P < 0.001) and HSS (P < 0.001) compared to preoperative values. Patient satisfaction at 1-month postoperative follow-up was up to 95%. The incidence of deep venous thrombosis was 16.3%. There was no incidence of postoperative infection.
The medial parapatellar approach is a understandable, easy to master and credible surgical approach for LUKA, showing a striking improvement in clinical outcomes without adverse events in the short-term follow-up.
通过内侧髌旁入路探讨外侧单髁膝关节置换术（LUKA）的技术优势和临床结果。
自 2022 年 8 月至 2024 年 6 月，共纳入 104 例行内侧髌旁入路 LUKA 的患者。收集手术时间、住院时间、手术并发症和随访时间。记录术前和术后的关节活动度（ROM）、牛津膝关节评分（OKS）和特种外科医院膝关节评分（HSS），并采用配对样本 t 检验进行分析。
回顾性病例系列研究的主要人口统计学数据包括性别（30 名男性和 74 名女性）、年龄（63.1±8.37 岁，范围 49-84 岁）、手术时间（86±17 分钟，范围 52-135 分钟）、住院时间（4.0±1.1 天，范围 3-8 天）和随访时间（9.9±5.7 个月，范围 1-23 个月）。与术前相比，ROM（P<0.001）、OKS（P<0.001）和 HSS（P<0.001）均有显著改善。术后 1 个月的患者满意度高达 95%。深静脉血栓的发生率为 16.3%。无术后感染发生。
内侧髌旁入路是一种易于理解、易于掌握且可靠的 LUKA 手术入路，在短期随访中无不良事件发生，临床结果显著改善。
