    Is your knee deviated backward while standing erect?

    Some people have knee joint deviated backwards when seen from the sides while the individual stands on their legs fully extended (i.e. when standing straight with full bodyweight on the feet). This condition is known as Genu recurvatum.

    The severity of this illness can vary although depending upon the angulation. It’s more common with females. It may be related to loose ligaments around the knee joint that might have been acquired by birth genetically, cerebral palsy etc.

    This condition might lead to knee pain, a decreased ability to walk or run, osteoarthritis etc. Strengthening of quadriceps muscles of the thigh is said to be helpful to retain the joints stability and decrease pain.

    However, depending on severity bracing or surgical intervention might also be needed.

    ECG: how to determine left and right axis deviation? 

    First let’s revise the basics of ECG related to axis deviation :

    • Normal if QRS complexes positive deflection in lead I or II
    • Lead I is 0 degree and lead II is +60 degree
    • Normal cardiac axis lies between -30 deg to 90 deg
    • Deflection moves towards the positive direction.
    • In a normal ECG with no axis deviation in both lead I and II QRS complexes have positive deflection that is to an upward direction.


    To determine axis deviation remember that you need primarily information of lead I and lead II only, and forget the rest.

    Now if QRS complex in lead I and II are negative and positive respectively what will be the axis deviation – right or left?

    Answer: as we said do determine axis deviation we need to move towards a positive direction, here we will move from lead I to lead II i.e. from 0 degree to +60 degree. Since this is a clockwise movement towards the right side this is a right axis deviation (RAD).


    If QRS complex in lead II and I are negative and positive respectively what will be the axis deviation – right or left?

    Answer: as we said do determine axis deviation we need to move towards a positive direction, here we will move from lead II to lead I i.e. from +60 degree to 0 degree. Since this is an anti-clockwise movement towards the left side this is a left axis deviation (LAD).
