EX-LE-4 (Nèixīyǎn, 内膝眼) — Inner Knee Eye
- Meridian
- Extra points (EX)
- Anatomical view
- anterior
- Point classification
- Medial knee-eye; counterpart of lateral Xiyan (ST35).
- Depth reference
- Oblique insertion 0.5-1.0 cun toward the center of the knee, directed slightly laterally.
- Moxibustion
- Suitable for moxibustion.
- Reference aliases
- EXLE-4; Neixiyan; 内膝眼; Inner Knee Eye
Anatomical location
On the knee, in the depression medial to the patellar ligament, when the knee is flexed (the medial member of the pair; the lateral one is ST35).
Traditional actions
Activates the channel, benefits the knee and dispels wind-damp.
Recorded indications
Primary: Knee pain, swelling and stiffness; difficulty in flexing and extending the knee
Secondary: Weakness of the leg; beriberi
How to read this reference
AcuAtlas separates anatomical location, traditional classification, recorded actions, indications, insertion-depth references, and moxibustion notes because these fields answer different study questions. The location statement is the orientation anchor. The classification and actions describe traditional reference categories, while indications summarize how checked educational sources associate the point with established teaching material. They are not a recommendation to select or stimulate the point.
Depth and moxibustion entries are reproduced as bounded reference notes rather than procedural instructions. Individual anatomy, technique, angle, clinical setting, and local professional standards can change what is appropriate. Review the cited documents and supervised training material before using any technical field. The normalized map coordinate is included only to place the point on the matching AcuAtlas body plate; it is not a substitute for palpation or anatomical assessment.
