The goose foot is an anatomical structure formed by three tendons: the sartorius, the internal rectus and the semitendinosus. The sartorius is the muscle composed of striated-type skeletal tissue that runs along the anterior surface of the quadriceps. The internal rectus belongs to the anterior and medial muscles of the body; while the semitendinosus belongs to the hamstring muscles.
This structure is a conflict zone due to the influence of the muscles that are part of it, so that it can give rise to an inflammatory process that results in tendonitis of the pes pes, which, in some patients, It can manifest itself as a simple discomfort or really be very intense pain. In this post we talk about goosefoot tendinitis, its symptoms, causes, diagnosis and treatment for it. Keep reading!

What is pes pes tendonitis?
Pes anserine tendonitis, also known as anserine tendonitis, is one that affects the tendons of the pes pes., which is named for the way the hamstring tendons insert into the anterointernal aspect of the proximal tibia.

Symptoms of pes tendonitis
The most characteristic symptom of goose foot is pain. During the early phases of this pathology, the patient may notice pain when starting to run, disappear during it, and increase the pain again at night. In general, the most common symptoms of goose foot are:
- Intense pain in the inner area of the knee, which usually increases when moving or standing up.
- Presence of edema and swelling on some occasions.
- Feeling of stiffness, generally during the first hours of the day and improves as the day passes.
- Loss of functionality, so Goosefoot pain can alter the patient's activities of daily living.

Causes of anserine tendonitis
The discomfort is caused by inflammation of the tendons of the goose foot, whether or not associated with inflammation of the anserine bursa.. This syndrome is more common in women with knee osteoarthritis and who are overweight.
Like all tendinopathies, the main cause is usually overuse, such as physical exercise, although there are also other underlying metabolic causes. It is also important to take into account factors such as the presence of degenerative diseases, such as osteoarthritis, overweight, type of physical activity that the patient practices or the biomechanics of gait.
As indicated, this is a more predominant pathology in women, due to the presence of a wider hip, so there is a greater chance of overloading this area if the insertion of the muscles is taken into account.
The goose foot tendonitis mainly seen in long distance runners. The causes include trauma, retraction of the posterior muscles of the thigh, exostoses or bony prominence in the medial area of the knee, flat feet, genu valgus or knee with lateral deviation of its axis.

Diagnosis and treatment of pes pes tendinitis
Various diseases and injuries can affect the health of the knees and lead to the symptoms of this tendinopathy, so it is important to consult a specialist so that he or she can assess the patient's various symptoms and, based on this, determine the appropriate treatment. for the patient.
How to differentiate pes anserinus tendinitis from other knee injuries?
Pain in the inner part of the knee can easily be confused with other conditions, such as osteoarthritis, bursitis, or a meniscal tear. What distinguishes pes anserinus tendinitis is that it has unique characteristics that allow a specialist to differentiate it through physical examination and imaging tests.
The pain is usually located just below the joint line., on the inner part of the leg, and increases when climbing stairs or standing up after sitting for a long time.
Another important difference is that Pes anserine tendinitis usually causes more specific and sharp discomfort, especially when pressure is applied to the tendon area. In bursitis, on the other hand, the pain is accompanied by more visible inflammation and a sensation of local heat.
If there is any doubt, the specialist may order an ultrasound or MRI to rule out cartilage or meniscus injuries. Identifying the exact cause of the pain is essential for applying the most effective treatment and relieving symptoms as quickly as possible.
How is anserine tendonitis diagnosed?
The clinical examination gives the specialist an impression of the cause of internal knee pain.. The diagnostic actions are the following: visual inspection and lateral check of both knees, palpatory examination of the region of pain and an evaluation of the range of motion in the knee and hip, as well as the strength of the muscles of these joints.
Sometimes additional imaging tests such as ultrasound, x-ray, and MRI are necessary.
How long does recovery from pes anserinus tendinitis take?
The duration of recovery depends on the degree of inflammation and the type of treatment followed. In mild cases, the patient usually improves within two to six weeks. with rest, physiotherapy, and strengthening exercises. However, if the injury is deeper, the process can take up to three months, especially if physical activity has been maintained without the necessary rest.
Throughout the recovery period, the physiotherapist will guide the patient through a gradual progression of low-impact exercises and controlled movements. Activities such as stationary cycling or swimming can be introduced in intermediate phases of rehabilitation, as they help maintain mobility without overloading the joint.
In any case, it is essential to respect the body's natural healing process and avoid putting undue stress on the knee before full recovery, as this could lead to relapses or chronic tendinopathies.
Recommended exercises to strengthen the pes anserinus.
Strengthening the muscles involved is essential for the treatment and prevention of this injury.Isometric exercises, those that activate the muscle without moving the joint, are highly recommended in the early stages. These exercises prevent quadriceps atrophy and reduce pain. For example, holding the leg extended for a few seconds with a slight contraction helps reactivate the muscle without putting friction on the tendon.
As inflammation subsides, gentle stretching exercises for the hamstrings, adductors, and quadriceps are incorporated. Balance or proprioceptive activities can then be added. These improve knee coordination and stability, reducing the risk of future overuse injuries.
It is important to emphasize that every routine should be supervised by a specialized physiotherapist, who will adapt the exercises to the patient's pace to ensure a safe and effective recovery.
Treatment of pes tendonitis
Once the expert's diagnosis is made based on the symptoms and imaging tests, the specialist will be the one to determine the most effective treatment for goosefoot tendonitis.

Initial treatment for pes pes tendinopathy should include rest of the affected knee. Isometric exercises may also be recommended to prevent quadriceps atrophy due to disuse.
Likewise, physiotherapy is another of the most effective treatments for this pathology. Ultrasound is one of the effective therapies for reducing the inflammatory process of anserine tendonitis.
In cases where conservative treatment is not sufficient, the trauma specialist would consider surgery if he or she sees it necessary and in very exceptional cases.
How to prevent pes anserinus tendinitis
Prevention is key to avoiding a recurrence of this condition. Maintaining good athletic technique and warming up properly before each exercise are essential habits for protecting tendons. Runners should avoid hard or uneven surfaces and regularly check their running shoes to ensure they provide adequate cushioning and support.
In addition, weight management and proper gait are important, as they help reduce pressure on the inner side of the knee. Complementing physical activity with strengthening and stretching exercises is also essential for maintaining balance among muscle groups. Adopting these precautions can make the difference between a stable recovery and the intermittent recurrence of pes anserine tendinitis.

I had left knee meniscus surgery. The result of the MRI says, faint subchondral edema, hyaline changes, grade 1 patellar chondromalacia, faint edema in the pre- and infrapatellar TCS and Beaker cysts. Can this be treated without surgery? Thank you.
Hello Omar,
At first glance it seems like a mild pathology. We can always try conservative treatments before surgery when there is no absolute surgical indication.
A hug.
Good morning
A month and a week ago I had a stretch in my right knee, it was an involuntary movement as a result of a crash playing futsala, they performed an MRI, but it said there was nothing new, however, I feel instability, inflammation sometimes, pain when performing some movements, for example when I try to turn my knee inward or kick a ball, is painful.
Hello Katerin, it would be recommended that if you have pain and discomfort you make a second consultation to confirm your diagnosis.

Good afternoon from Angola. About seven months ago I had an arthroscopic operation on my right knee due to an injury to the internal meniscus. Today I had pain in my left knee where my specialist told me that I had crow's foot tendonitis and informed me through a physical examination that I had an injury to the internal meniscus of this knee and that I should have an arthroscopy and an exceresis of the meniscus. My question is should I have surgery or can I have some infiltration treatment with resting steroids or physiotherapy. What dou you recommend.
Hello Osmany,
You should have an MRI of your knee to see if you have meniscal pathology. If there is, I do not recommend surgery.

Hello, I practice judo. Five weeks ago I was kicked on the left side of my right knee. They diagnosed me with tendonitis of the medial vastus and the grasil. They told me 10 physiotherapy sessions. I have had five, but I don't know how long it will take to heal. I can already bend and go down stairs, but I don't know if I can run or do judo again. I'm scared because I feel like if I do it or run or do strengthening exercises, I'm going to tear it or I feel like my leg will stop.
I don't know if you could answer those questions for me.
Hello Armando,
It's important not to rush things. Check with your physical therapist before you start running or judo again. Even if you feel better, forcing your recovery could increase your risk of re-injury. Progressive, controlled rehabilitation is key to returning to activity without problems.

Hello Dr. from Colombia, 6 years ago I had surgery for my anterior cruciate ligament and a partial tear of the meniscus. The procedure was arthroscopic. I was playing 3 games a week and during one movement I felt pain in the same operated knee (left), on the inside. Symptoms of pain, a little stiffness, it is uncomfortable. I don't know if it is tendonitis or something else that could be affecting it. What do you recommend I do? Thank you.
Hi John,
It is possible that the knee is reacting to repeated stress, or there may be some injury to internal structures. We suggest rest, ice application, and consultation with a specialist for a more accurate evaluation.

I am a 67-year-old woman. I have had several serious falls and severe pain, and I was diagnosed with swollen goose foot. I have taken numerous medications and physical therapy, and for almost eight months now, I have only received relief. I had an injection in my right knee, which improved for two months. I had a spinal block 20 days ago because an MRI showed a herniated disk, but it only provided temporary relief.
What else could I do so that I can finally walk without pain and have a better quality of life?
Thank you in advance!
Hello Rosalba,
Thank you for sharing your case. In your case, a comprehensive evaluation that takes into account both the knee problem and the herniated disc is important, as both may be contributing to the pain and walking limitations. In cases where conventional treatments don't achieve lasting results, it may be necessary to review the tests, adjust the therapy, or explore specific alternatives based on your condition and progress.
It's recommended that a specialist thoroughly evaluate your case to suggest personalized options to help you improve your mobility and quality of life. If you'd like, you can schedule an appointment with our team, and we'll be happy to help you find an effective treatment.

Once a diagnosis of pes anserinus tendinitis has been made, would TENS electrostimulation be useful? Thank you.
Hello Maria,
In some cases, TENS can help temporarily relieve pain in pes anserine tendinitis, but it doesn't address the underlying cause. The most important approach is usually to reduce inflammation, improve biomechanics, and perform specific exercises guided by a professional.
