Q angle # Quadriceps angle and Patellofemoral biomechanics

Detailed description of Q angle also known as quadriceps angle and its biomechanical signifiance.The neteffect of pull of quadriceps muscle and patellar tendon are analysed clinically by using this q angle. Its angle formed between line joining ASIS and MID POINT of patella with line joining MIDPOINT of patella with tibial tuberosity.
The normal value of Q angle is 10-15 degree and an alteration in Q angle shows there is increased lateral pull on patella which can lead to decrease in patellar stabilization.Some studies show that Q angle is higher in females due wider pelvis etc.
When Q angle is increased it lead on to increase in lateral pull of patella,which can lead to patellar subluxation,or dislocation.There are several abnormalities that can lead on to increase lateral forces on patella such as GENU VALGUM,IT BAND TIGHTNESS,MEDIAL FEMORAL TORSION,PRONATION OF FOOT,LATERAL TIBIAL TORSION.

Sir you are an awesome teacher of biomechanics. ....I saw all your vedios for studies 🤩keep going sir🙌🏻🙌🏻🙌🏻🙌🏻

[alfredocortes]

if pain happens inside the leg inside the patella, and feet are unbalanced, what parts of body should I strengthen and stretch/ thank you

[hemanthchintu]

I love watching your vedios which gives more confidence on subject thank you sir ... loads of love from andhrapradesh, svims university tirupathi🔥🔥🔥🔥

[crazybytesncookiesworld]

You are my good sir😊, i really appreciate you

Hi. Very informative! I can feel pressure, stress and pain around the kneecap. it makes my knee feel weak. How can I find the real reason for a large q angle and resolve my PFPS ?

[MuhammadMizanurShuvra]

Great video. But I am confused. If there is STJ pronation then the adduction and plantar flexion of the Talus lets the tibia to internally rotate or internal rotation, which is like a medial rotation. This is the opposite of the lateral tibial torsion that you said also increases the Q angle. So, can you please explain how does pronation of the foot increase the Q angle if the tibia is internally rotating during excessive foot pronation? Thanks

[tmeena]

Thank you sir it's very good explaination 🤝🤝🥰

[josnamoljohnson]

Super class sir 👌👌👌👌 good explanation and lectures 🤝 i like it, thanks sir thanks for making 😊

[gayatrisinha]

Nicely put up all the related causes...

[thorgamer]

Sir my hips are wide
So tell me causes of wide hip
And solution please

[muhammedmd]

So good you really make it so easy. Thank u sir

[aiswaryapp]

Nice class sir🤝🤝, thank u for making this portion very easy

[shlokkamerkar]

sir can we can strengthen the leg and can we bring it too the normal conditions.
can we solve the problem of vmo by band exercises

[medicogivemered]

Kindly make videos less than 10 min.will take less time to wach .and can watch maximum .

[adarshkhanduri]

Beautifully explained sir but i have a question that in what condition medial femoral tortion and tibial lateral tortion can take place together ? Btw all doubts clear sir ✌️

[revathir.s]

Nice class sir... 👏👏👏you made it is very simple....really it is understandable... thank sooo much sir🤗

[gayatrisinha]

Sir could you tell me best colleges for MPT abroad...fee structure and eligibility criteria
