How does genu recurvatum affect gait?
Genu recurvatum is operationally defined as knee extension greater than 5′. Individuals who exhibit genu recurvatum may experience knee pain, display an extension gait pattern, and have poor proprioceptive control of terminal knee extension.
How do you assess genu recurvatum?
The best way to clinically diagnose the amount of hyperextension of the knee is to measure the patient’s heel heights. If there is a normal contralateral (opposite) knee to compare to, an increase in heel height can be diagnostic for genu recurvatum.
What would you see on a patient with genu recurvatum?
The most common symptoms associated with this condition include pain, weakness, instability, leg-length discrepancy, and decreased range of motion. Genu recurvatum can be congenital33 or acquired secondary to trauma,14 cerebrovascular accident, polio,23 physeal arrest,6 Osgood-Schlatter disease,25 or prolonged casting.
What happens in genu recurvatum?
Genu recurvatum is a deformity in the knee joint, so that the knee bends backwards. In this deformity, excessive extension occurs in the tibiofemoral joint. Genu recurvatum is also called knee hyperextension and back knee. This deformity is more common in women and people with familial ligamentous laxity.
How do you measure Q angle?
The Q angle is measured by dropping a plumb-line through the tibial tubercle and middle of the patella and another from the ASIS to intersect with the first line at the mid-patella. The angle created by the intersecting lines is the Q angle.
How do you diagnose a hyperextended knee?
How To Know if You Have Knee Hyperextension
- Knee Pain. You may feel mild to severe pain in your affected knee.
- Poor Movement. You may find straightening or flexing your affected knee to have become difficult.
- Swelling. Swelling and stiffness may develop around your affected knee.
- Poor Stability.
How do you reduce genu recurvatum?
Genu recurvatum was generally reduced in all subjects by increasing the amount of plantarflexion resistance of the articulated AFO. The ankle and knee joint angle and moment parameters showed statistically significant differences among the spring conditions of the AFO (Table 3).
What is the normal Q angle?
It is well-known that the normal Q angle should fall between 12 and 20 degrees; the males are usually at the low end of this range; while females tend to have higher measurements [6,10–13].
What is significance of Q angle?
Clinical Importance The Q angle formed by the vector for the combined pull of the quadriceps femoris muscle and the patellar tendon, is important because of the lateral pull it exerts on the patella. Any alteration in alignment that increases the Q angle is thought to increase the lateral force on the patella.
What causes knee hyperextension during gait?
Nerve damage, such as Brain injury (congenital, stroke-induced or traumatic), or poliomyelitis, may cause hyperextended gait because of muscle (quadriceps or calf muscle) atrophy, spastic plantar flexion of the ankle, or contractures of the heel tendons.
What is Q angle?
The Q angle, which is also known as quadriceps angle, is defined as the angle formed between the quadriceps muscles and the patella tendon.
What is the orthosis for genu recurvatum?
Ankle-foot orthoses are used to improve genu recurvatum, but evidence is limited concerning their effectiveness. Therefore, the aim of this study was to investigate the effect of changing the plantarflexion resistance of an articulated ankle-foot orthosis on genu recurvatum in patients post-stroke.
