The location of pes anserinus insertion in Thai people.
BACKGROUND
The semitendinosus and gracilis tendon are commonly used for ligamentous reconstruction. Inaccurate skin incision may cause complications such as cutting the main tendon, inadequate graft length and sciatic nerve injury. There have been no reports about the insertion site of these tendons among Thai people.


OBJECTIVE
To describe the distance between pes anserinus insertion and tibial tuberosity.


METHODS
Eighty five cadaveric knees were dissected. We measured the distance between tibial tuberosity and tendon insertion and collected by the side and sex.


RESULTS
The median distance between tibial tuberosity and tendon insertion was 0.5 centimeter at the vertical plane and the horizontal plane below tibial tuberosity was 2 and 2.5 centimeters in female and male, respectively. There was a statistically significant difference of the horizontal plane between male and female (p-value < 0.01).


CONCLUSIONS
The location of pes anserinus insertion in Thai population may be more proximal than previous report.
