To determine the 50 most cited studies on posterior tibial slope (PTS) in joint preserving knee surgery and assess their level of evidence, objective study quality scores as well as to examine whether the study quality correlated with the citation count and citation density in the top 50 list.
A literature search on Web of Science was performed to determine the 50 most cited studies on the topic of PTS in joint preserving knee surgery between 1990 and 2022. The studies were evaluated for their bibliographic parameters, level of evidence rating (LOE), citation counts, the Modified Coleman Methodological Score (MCMS), the Methodological Index for Non-Randomized Studies (MINORS), and the Radiologic Methodology and Quality Scale (MQCSRE).
Of the top 50 list, 16 studies were published in the American Journal of Sports Medicine. A total of 23 studies were produced in the United States (46%). Of 10 different study types, case control studies (n = 16, 32%) and cadaveric studies (n = 10, 20%) were most common. 15 studies (30%) were purely radiological studies. 6 studies were level II (12%), 23 level III (46%), 15 level IV (30%), and 6 level V studies (12%), respectively. The number of citations ranged from 42 to 447 (mean 105.6 ± 79.2 citations) and showed a mean citation density of 10.3 ± 5.2, composed of the decades 1994 - 2000 (8.3 ± 4.1), 2001 - 2010 (11.1 ± 5.9), 2011 - 2019 (10.1 ± 5.1). Mean quality scores were 55.9 ± 13.0 for MCMS (n = 18), 14.5 ± 3.2 for MINORS (n = 18) and 18.1 ± 3.7 for MQCSRE (n = 20), respectively. High citation counts did not correlate with higher study quality scores (p > 0.05). Radiological studies were not significantly cited more often than non-radiological studies (mean 116.9 ± 88.3 vs. 100.8 ± 75.8 citations; p > 0.05).
In joint preserving knee surgery, the 50 most cited studies on PTS did not represent a ranking of the highest methodological quality scores. Citation counts and citation density over the past three decades did not significantly differ, even though the number of articles in the presented list multiplied over the same period. This list can serve as a reference tool for orthopedic surgeons aiming to review PTS literature.
确定关节保留型膝关节手术中关于胫骨后倾（PTS）被引用次数最多的50项研究，评估其证据水平、客观研究质量评分，并检查研究质量与前50名列表中的研究质量是否与引用次数和引用密度相关。
在科学网进行文献检索，以确定1990年至2022年间关节保留型膝关节手术中关于PTS主题被引用次数最多的50项研究。对这些研究的文献参数、证据水平评级（LOE）、引用次数、改良科尔曼方法学评分（MCMS）、非随机研究方法学指数（MINORS）以及放射学方法和质量量表（MQCSRE）进行评估。
在前50名列表中，16项研究发表于《美国运动医学杂志》。共有23项研究在美国开展（占46%）。在10种不同的研究类型中，病例对照研究（n = 16，占32%）和尸体研究（n = 10，占20%）最为常见。15项研究（占30%）为纯放射学研究。分别有6项研究为II级（占12%）、23项为III级（占46%）、15项为IV级（占30%）和6项为V级研究（占12%）。引用次数范围为42至447次（平均105.6 ± 79.2次引用），平均引用密度为10.3 ± 5.2，由1994 - 2000年（8.3 ± 4.1）、2001 - 2010年（11.1 ± 5.9）、2011 - 2019年（10.1 ± 5.1）这几个十年组成。MCMS的平均质量评分为55.9 ± 13.0（n = 18），MINORS的平均质量评分为14.5 ± 3.2（n = 18），MQCSRE的平均质量评分为18.1 ± 3.7（n = 20）。高引用次数与较高的研究质量评分不相关（p > 0.05）。放射学研究的被引用频率并不显著高于非放射学研究（平均116.9 ± 88.3次引用对100.8 ± 75.8次引用；p > 0.05）。
在关节保留型膝关节手术中，关于PTS被引用次数最多的50项研究并不代表方法学质量评分最高的排名。尽管在同一时期列出的文章数量成倍增加，但过去三十年的引用次数和引用密度并无显著差异。该列表可作为骨科医生回顾PTS文献的参考工具。
