It is increasingly common for patients to go to the physiotherapy consultation with their own diagnosis and surprised by not improving after having performed exercises, stretching and all the remedies they have read on the Internet or that a friend has recommended.
El pain on the external face of the knee it is often a very frequent location of pain It does not remit easily and many times it is because it does not have an accurate diagnosis.
The purpose of this article is to give you know the most frequent pathologies that can appear on the lateral aspect of the knee so that in this way, you understand the importance of going to the specialist to direct your recovery as soon as possible.
In a previous post, we explained what was the iliotibial band syndrome and as we mentioned, NOT all the pain in the external face is produced by this structure, the difficulty of the differentiation of the pathological picture resides in that often the symptomatology is very similar.
Some of the pathologies that can be given are:
External meniscus injury:
In the knee we have two meniscus, the internal and the external. They are a kind of fibrocartilaginous pads that have the function of increasing congruence and joint stability and improving the transmission of loads. It is important to gather information about the position of the knee at the time of the injury, if it was suddenly or late inflamed, if there was clicking, pain or blockage sensation since it is very important for the diagnostic orientation. The symptomatology is very variable, from great inflammation, low quadriceps tone to intermittent pain of less disability, or limitation of mobility. The treatment will depend on the type of injury and, whenever possible, the conservative will be chosen, leaving the surgical procedure for certain cases.
The popliteus is a small muscle, but with an important Stabilizing function of the external meniscus and of the control of the knee during the march. The tendon of this muscle is covered by a sheath and when there is an affectation, fluid accumulates between the sheath and the tendon.
The patient refers pain in the back and outside of the knee almost always with functional limitation when walking and in sports activities especially when it descends (slope of slopes). The diagnosis will be made through certain exploratory tests and ultrasound can help confirm their involvement.
Superior tibioperoneum ganglion:
The appearance of a lump on the external face of the neck of the fibula (slightly lower than the knee) is the warning sign in the patient. It occurs as a result of a joint overload and of repeated microtrauma, such as continuous running.
An alteration of the biomechanics of the knee and / or chronic ankle injuries can contribute to its appearance. It is important to perform imaging tests to confirm your diagnosis and thus proceed to the most appropriate treatment.
Highlight of the biceps femoral tendon:
It appears in race, cycling and soccer athletes. The athlete notes a "high" on the posterolateral face above the head of the fibula. You can usually reproduce it with the knee to 90º of flexion and standing fixed on the floor, when trying to bend and contract the musculature the abrupt projection is observed.
La magnetic resonance It detects the anatomical alteration that causes the protrusion, although at a clinical level it is more interesting to perform an ultrasound to see how the structure behaves dynamically.
Injuries of the lateral collateral ligament:
It is less frequent than that of the internal collateral ligament. It usually occurs after a bad gesture that implies the overstretching of the external part of the joint. This lesion is usually associated with involvement of the anterior cruciate ligament and other intraarticular structures. therefore, it is important to carry out complementary tests.
From Healthing we recommend that in the case of pain in the lateral aspect of the knee ask appointment with the specialist so that after a thorough clinical examination, diagnose and schedule treatment early to shorten recovery times.
