Anterior knee pain (AKP) is a widespread problem among young athletes and soldiers. There are many theories on the etiology of AKP but there is little reference to myofascial trigger points (MTrPs) as a possible contributor.
To evaluate the association between AKP and prevalence of active and latent MTrPs in the hip and thigh muscles in soldiers.
A cross-sectional study was conducted in the Beer-Sheva military outpatient physical therapy clinic. Subjects were 42 men and 23 women referred for physical therapy, 33 with a diagnosis of AKP (cases) and 32 with upper limb complaints (without AKP, controls). All subjects underwent physical evaluation by an examiner blinded to their identity and medical condition. The following muscles were assessed bilaterally for active or latent MTrPs: rectus femoris (proximal), vastus medialis (middle and distal), vastus lateralis (middle and distal) and gluteus medius (anterior, posterior and distal).
In six out of eight areas, the cases had a higher prevalence of total active and latent MTrPs than the controls. When summarizing MTrPs by muscle, cases had significantly more MTrPs than controls in each muscle. The largest difference was found in vastus medialis and vastus lateralis; nearly half of the cases had MTrPs in these muscles.
Subjects with AKP have a greater prevalence of MTrPs in their hip and thigh muscles than controls, indicating an association between MTrPs and AKP. Further research is necessary to determine whether MTrPs are the cause or the consequence of AKP.
前膝痛（AKP）是年轻运动员和士兵中普遍存在的问题。对于 AKP 的病因有很多理论，但很少有提到肌筋膜触发点（MTrP）可能是一个致病因素。
评估士兵髋关节和大腿肌肉中 AKP 与活跃和潜伏性 MTrP 患病率之间的关系。
在 Beer-Sheva 军事门诊物理治疗诊所进行了一项横断面研究。受试者为 42 名男性和 23 名女性，因物理治疗而就诊，其中 33 人被诊断为 AKP（病例），32 人有上肢投诉（无 AKP，对照组）。所有受试者均由一名对其身份和医疗状况不知情的检查者进行体格检查。评估双侧以下肌肉的活跃或潜伏性 MTrP：股直肌（近端）、股内侧肌（中部和远端）、股外侧肌（中部和远端）和臀中肌（前、后和远端）。
在 8 个区域中的 6 个区域，病例的总活跃和潜伏性 MTrP 患病率高于对照组。当按肌肉总结 MTrP 时，病例在每个肌肉中的 MTrP 明显多于对照组。最大的差异出现在股内侧肌和股外侧肌；几乎一半的病例在这些肌肉中有 MTrP。
患有 AKP 的受试者髋关节和大腿肌肉中的 MTrP 患病率高于对照组，表明 MTrP 与 AKP 之间存在关联。需要进一步研究以确定 MTrP 是 AKP 的原因还是后果。
