Despite emphasis on classifying meniscal tears based on healing potential of the tear, research has concentrated on unstable knees, and few reports have provided information regarding associated clinical variables in stable knees.
To report on a large series of meniscal tears in stable knees that have been carefully mapped by tear shape and tear zones to allow comparison with meniscal tears in unstable knees.
Prospective case series, reviewed retrospectively.
A total of 1485 meniscal tears in stable knees were evaluated. Preoperatively, each patient underwent a standardized assessment. Each tear was carefully mapped at arthroscopy. Statistical analysis was performed to determine factors that may be associated with peripheral meniscal tears.
The distribution and shape of tears varied significantly within the radial and circumferential zones in this stable knee population. Five prospective variables were associated with peripheral tears: gender, presence of an effusion, positive McMurray test, varus alignment, or a loss of extension more than 5 degrees.
Patient demographic information and physical examination can be useful in identifying patients who may have a peripheral meniscus tear.
尽管强调根据半月板撕裂的愈合潜力对其进行分类，但研究主要集中在不稳定膝关节，很少有报告提供关于稳定膝关节相关临床变量的信息。
报告一系列稳定膝关节中的半月板撕裂情况，这些撕裂已根据撕裂形状和撕裂区域进行了仔细绘图，以便与不稳定膝关节中的半月板撕裂进行比较。
前瞻性病例系列，回顾性分析。
对1485例稳定膝关节中的半月板撕裂进行评估。术前，每位患者均接受标准化评估。在关节镜检查时对每个撕裂进行仔细绘图。进行统计分析以确定可能与半月板外周撕裂相关的因素。
在这个稳定膝关节人群中，撕裂在径向和圆周区域内的分布和形状有显著差异。五个前瞻性变量与外周撕裂相关：性别、有无积液、麦克马瑞试验阳性、内翻畸形或伸直受限超过5度。
患者人口统计学信息和体格检查有助于识别可能存在半月板外周撕裂的患者。
