Q Angle of the Knee
A well-functioning knee is important for mobility. The knee must be able to support the weight of the body during activities such as walking or running. A normal alignment of the knee is important for its function. The Q-angle of the knee provides useful information about the alignment of the knee joint. The Q-angle is the angle between the quadriceps tendon and the patellar tendon. An increased Q-angle is a risk factor for patellar subluxation. The Q-angle (quadriceps angle) is formed in the frontal plane by two line segments. The first line drawn is drawn from the anterior superior iliac spine (ASIS) to the center of the patella. A second line is drawn from the center of the patella to the tibial tubercle. The angle is formed by the two lines is called the Q-angle. Find the patella and its border; find the center of the patella; find the tibial tubercle; draw a line from the ASIS to the center of the patella and a second line from the tibial tubercle through the center of the patella. The normal Q-angle is variable. In extension, the normal Q-angle for males is usually 14 degrees, and in females it is approximately 17 degrees. The normal Q-angle in flexion is approximately 8 degrees. A wider pelvis and increased Q-angle in females is linked to knee pain, patellofemoral pain, and ACL injury. The alignment of the patellofemoral joint is affected by the patellar tendon length and the Q-angle. It is best to measure the Q-angle with the knee in extension as well as flexion. Larger Q-angle plus a strong quadriceps contraction can dislocate the patella. The Q-angle is increased by genu valgum, external tibial torsion, femoral anteversion, lateral positioned tibial tuberosity, and tight lateral retinaculum. CT scan study of the patellofemoral articulation is found to be very helpful. An increased Q-angle in the knee will lead to an increase in lateral subluxation forces on the patella which may lead to pain, wear of the implant, and mechanical symptoms. When doing a total knee replacement, avoid the techniques that will cause increased Q-angle, such as internal rotation of the femoral component of the tibial component. Avoid medialization of the femoral component. Avoid lateral placement of the patellar component. The patellar prosthesis should be placed either in the center or slightly medial. You will put the patella slightly medial, but you will put the femoral component opposite to that; it will be slightly lateral. Terms used to describe a triad of anatomic features or findings which will increase the Q-angle include excessive femoral anteversion, genu valgum, and external tibial torsion or pronated feet. Symptoms for miserable malalignment syndrome include anterior knee pain, pain under the patella, and stiffness of the knee joint. When examining a patient for patellofemoral pain, alignment is important, including rotational alignment.

Thank you sir

[@raminarabnejad3741]

thank you too

[@ashrafrajput9877]

Very nice

[@brittany1991]

Can a derotational femoral osteotomy fix patellar tracking? Thank you sir

[@2legit437]

Where exactly do you measure the angle? How many inches above the superior border of the patella? Or how many inches below the ASIS?
TIA

TQ 🙏🏿

Is there anyhow to fix the excessive Q angle? Rather than surgery

[@LEARNING-MEDICAL-EDUCATION]

how do u make this type of animation of anatomical structure

[@peelyb]

Can someone tell me - I have very knock knee problems but my osteopath will realign my bones 100%. I have mild arthritis in both knees and severe in my lumbar. My question is about my knees. If I keep proper alignment and strength is it possible to avoid further arthritis? The stress will be taken off the damaged cartilage. 🙏

Sir, my knees are flexible, due to which my legs turn inwards and it hurts to stand, please tell me some remedy.

[@deejaypratz9583]

Sir can I ask a question sir, I am involved in a vehicle accident. I had a proximal tibia fracture, on my left knee. It was schatzker type 1, my doctor said it can be surgical or non surgical. So I chose non surgical procedure, I chose long knee casting. This recent days the cast was removed 2 days after I am continuously feel the pain and I cannot even Stretch my leg. If there is possibility that I cannot walk normally even if its already heal? Sir, I need some concreate informations sir. I hope you can give some information and advise sir, thank you so much and Godbless.

[@omarelgarhy3167]

Thank you, but what is the treatment for an excessive Q angle?

[@igorliy3666]

Distal femoral osteotomy with varisation

[@omarelgarhy3167]

@@igorliy3666 Great, thanks!

[@meetdesai3106]

Excessive q angle must require a surgury
As physiotherapist ,
While gradually developing these conditions,
I might release the IT and biceps femoris and increas strength of Gracilis muscles, SM ,ST muscles . Also i will add conditions wise treatment and find out other muscles imbalance develop in body due to this condition. And treat accoding to it .
