Saphenous N

Question 1

Anatomy

Answer 1

SENSORY

• largest termination of femoral N, passes posteriomedial from femoral triangle to Hunter’s canal b/w VMO and adductor longus
• branches twice before leaving canal into infrapatellar and descending branches
• infrapatellar branch -> medial knee and medial knee joint
• descending branch -> medial side of foot

Question 2

Origins of mechanical irritation

Answer 2

Genu varum (compression)
Genu valgum (tractional) 
Internal tibial torsion 
Direct trauma 
Medial meniscus protrusion
Knee joint instability 
Obesity 
Stretching in knee flex, repetitive motion

Question 3

Examination

Answer 3

PFT -> 4 fingerbreadths above medial condyle
Tinel’s sign
LLTT -> prone hip extension and knee flexion
MSTT/MMT -> thigh adduction, knee extension against resistance
Movement analysis -> avoidance of terminal knee extension, history of traumas, surgeries (meniscus or TKA)

Question 4

Treatment

Answer 4

relieve pressure, myofascial manipulation, muscle stretching, decrease loading activity
decrease inflammation if present
desensitization
