摘要

目的探讨髌骨股骨痛（PFP）患者膝关节吱吱作响、股四头肌厚度和等长力量之间的关系：设计：横断面：主要结果测量：主要结果测量：患有髌骨股骨痛（PFP）的参与者接受膝关节褶皱的存在、频率和严重程度的评估。获得股四头肌（股直肌、股内侧肌和股外侧肌）静止和收缩时的实时超声波图像，并测量两种情况下的肌肉厚度。进行最大自主等长收缩测试以测量膝关节伸肌力量。使用逻辑回归和线性回归探讨了膝关节褶皱与股四头肌肌肉厚度和膝关节伸肌力量之间的关系：共纳入了 60 名 PFP 患者（年龄：24 岁；60% 为女性；38% 有膝关节褶皱）。膝关节皱襞的严重程度与静止时（R2 = 0.19 和 0.09）和收缩时（R2 = 0.16 和 0.07）的股直肌和内侧肌厚度有关，与收缩时（R2 = 0.08）的外侧肌有关。等长膝关节伸肌力量与膝关节皱襞的存在、频率或严重程度无关：结论：膝关节褶皱的严重程度与 PFP 患者股四头肌厚度较低有关。结论：膝关节褶皱的严重程度与 PFP 患者股四头肌厚度较低有关，膝关节褶皱的存在和频率与股四头肌厚度或膝关节伸肌力量之间没有关系。

Is there a relationship between knee crepitus with quadriceps muscle thickness and strength in individuals with patellofemoral pain? A cross-sectional study

Objective

To explore the relationship between knee crepitus, quadriceps muscle thickness and isometric strength in individuals with patellofemoral pain (PFP).

Design

Cross-sectional.

Participants

Individuals with PFP.

Main outcome measures

Participants with PFP underwent assessments for presence, frequency and severity of knee crepitus. Real-time ultrasound images of the quadriceps muscles (rectus femoris, vastus medialis and lateralis) at rest and during contraction were obtained, muscle thickness was measured in both conditions. Maximal voluntary isometric contraction tests were performed to measure knee extensor strength. The relationship between knee crepitus and quadriceps muscle thickness and knee extensor strength was explored using logistic and linear regressions.

Results

Sixty individuals with PFP were included (age: 24; 60% women; 38% with crepitus). Knee crepitus severity was related to rectus femoris and vastus medialis thickness during rest (R² = 0.19 and 0.09, respectively) and contraction (R² = 0.16 and 0.07, respectively) and with vastus lateralis during contraction (R2 = 0.08). Isometric knee extensor strength was not related to knee crepitus presence, frequency, or severity.

Conclusion

Higher severity of knee crepitus is related to lower quadriceps muscle thickness in individuals with PFP. There is no relationship between the presence and frequency of knee crepitus with quadriceps muscle thickness or knee extensor strength.

期刊介绍： Physical Therapy in Sport is an international peer-reviewed journal that provides a forum for the publication of research and clinical practice material relevant to the healthcare professions involved in sports and exercise medicine, and rehabilitation. The journal publishes material that is indispensable for day-to-day practice and continuing professional development. Physical Therapy in Sport covers topics dealing with the diagnosis, treatment, and prevention of injuries, as well as more general areas of sports and exercise medicine and related sports science. The journal publishes original research, case studies, reviews, masterclasses, papers on clinical approaches, and book reviews, as well as occasional reports from conferences. Papers are double-blind peer-reviewed by our international advisory board and other international experts, and submissions from a broad range of disciplines are actively encouraged.
