hundred and thirty female athletes were examined for navicular drop, Q angle, genu recurvatum, Keywords: Posture; knee injuries; risk factors; athletes. 1. Relationship Between Q Angle and Knee Injuries Prevalence in Elite volleyball players (35 male and 35 female, age of ± years. Anterior knee pain syndrome (AKPS) represents a significant challenge for patients and for clinicians. With the knee in an extended position, intratester Q- angle intraclass correlation coefficients (ICC) .. AKPS is more common in females.
Furthermore, the increased Q angle causes the quadriceps to pull on the patella, which will encourage it to displace. When the patellar tendon is excessively long, a high-riding patella exists and lateral displacement of the patella may occur easily. The increased Q angle also causes the feet to be more pronated and flattened.
Whether or not the Q angle was the cause or result, recent studies have shown that custom-made, flexible orthotics will reduce pronation, put less stress on the knee, and improve the Q angle. The foot will also function better with a properly fitted orthotic because it will allow the subtalar joint to function more effectively. The body will then require less effort for forward propulsion and provide for improved shock absorption.
Strength and agility training are also very important for female athletes.
Boys have historically been trained from an early age in activities that increase their strength, agility and hand-eye coordination. Typically, young girls are at a disadvantage when they decide they want to play sports at an older age, because their lack of coordination and agility puts them at a greater propensity to injury. Noncompetitive balance and agility training, using a wobble board or similar device, may enhance proprioceptive function and help reduce the rate of injury.
Hormonal issues also are important in explaining a female athlete's susceptibility to injury. A lack of circulating androgens discourages the development of large and more powerful muscles, which act as a protective mechanism for the joints.
Ideally, the quadriceps muscles should be twice as strong as the hamstrings. When there is an imbalance, the ACL is more susceptible to tearing. Also, estrogens increased during the menstrual cycle, increase the laxity in connective tissue, and may make the female athlete more susceptible to an injury during those times. The estrogens also provide more endurance, which will allow female athletes to put longer periods of stress on their joints.
Understanding The Q Angle And Its Role With Injuries - Runners Connect
Because of the increased body fat ratio of a female, stress on the joints is increased. The ACL is most often injured with a jump or an abrupt change in direction, which happens about seven times more frequently during a game or competition because of the increased intensity.
Athletes who have injured the ACL usually describe it as a popping sensation, followed by swelling a couple of hours later, and a feeling that something is wrong.
Today, with advanced surgical techniques and rehabilitation procedures, the recovery period for ACL injuries has been shortened. In conclusion, it is a fact that women athletes are four to six times more prone to injuries of the ACL than male counterparts playing the same sports. The biggest reason for more injuries is due to anatomical differences, the Q angle being the most significant.
If you treat female athletes, it's important that you check them for foot pronation problems and have them wear custom-made orthotics. Instruct athletes in a program of proprioceptive neuromuscular education using a wobble board or similar device. Stress the importance of building up the quadriceps and hamstring muscles to support the knee.
Because of a lack of nutrients, it is important to have supplements that support a woman's normal hormone cycles and reduce the changes of elevated hormone levels. When these techniques are followed, women can participate in athletics with less susceptibility to injury. References Knee injury patterns among men and women in collegiate basketball and soccer.

Principles and Their Application. Illustrated Orthopedic Physical Assessment, 2nd edition. Although point 3 suggests correlation between a laterally placed knee and patellofemoral pain, it is highly doubtful that any therapist is going to be able to spot a 2.
This muscle lies on the inside of the thigh. Female runners suffering from PFPS are very often given strengthening exercises. In an attempt to end their pain. If your knee is being pulled to the outside because of your wide hips and excessive Q angle, strengthening the muscles on the inside of the thigh will help pull it back, right?
Unfortunately, once again, despite the attractiveness and apparent logic of such a solution, the research does not support such assumptions.
Q Angle and Knee Pain
Dissection studies negate any link between patellofemoral pain with size, length or angle of the VM. So, if PFPS in female runners is not a product of wide hips, a larger Q angle, maltracking knees or weak VMs, why is it that female runners seem to suffer it more than male runners? There is some fantastic research currently happening into gender specific running injury screening.
And prevention but as of yet the results are far from conclusive. It obviously is but when it comes to running related injury. Pain, Injury and Thresholds Every tissue in your body has a threshold. A maximum load it can take before damage results.
Asking them to do more than they are capable of produces pain. In a word, pain. With the idea that we will immediately modify what we are doing. A system of defence, and certainly not the enemy. For further protection following either a near miss or actual tissue damage, our nervous system reduces the pain threshold.
Q Angle and Knee Pain
Alarm bells now ring at slightly lower levels of activity than before. Reducing our capacity in this way ensures that we give our body time to heal. However, if we ignore the pain warnings, the nervous system will react by reducing the pain threshold for that tissue even more. And will continue doing so until we essentially start listening.
In other words, our system becomes overly sensitized. And it takes increasingly less activity for us to start feeling pain. Imagine you run too much one week, too fast or too many days in a row. During one of your runs, your knee starts hurting at mile 6.
You are crossing a pain threshold. Your body goes into protective mode. The more serious the damage or threat the more protective your system gets. A few days later you only manage 2 miles.
Until you stop provoking your system into protecting itself, it will continue to decrease pain thresholds. It may even start sending pain out to new areas, even to the other knee. The problem with knees is they are used so much in everyday activity. Rather like the ITB band, the Achilles tendon or plantar fascia.
With regards to knee pain, everyday activities that you may not realise increase system threat include: Getting into, out of or holding a squat position, e. Keeping the knees in one position, e.
