About Femoroacetabular Impingement (FAI)

FAI is a fairly common athletic hip injury that occurs in sports like football or rugby that involve cutting, pivoting and rapid directional changes. Your hip is a ball-and-socket joint, where the head of the femur (thigh bone) rotates within the acetabulum capsule. The capsule is lined with a fibrocartilaginous band called the labrum, and is lubricated by synovial fluid to allow the femur head to glide smoothly.

The labrum can become damaged or torn when the femur head pinches up against the acetabulum, causing the hip to become stiff and painful, and limiting range of motion. If left untreated, FAI can lead to hip arthritis and long-term disability.

FAI Symptoms and Causes


  • Stiffness in the upper thigh

  • Pain and stiffness in the hip and/or groin

  • Reduced hip range of motion

  • Hip pain after prolonged sitting

  • Pain ranging from dull to sharp when squatting

  • Clicking or locking of the hip joint


  • Formation of a bony growth on the head of the femur (Cam FAI)

  • Formation of a bony growth in the hip socket (usually in early childhood)

  • High intensity physical activity with cutting and pivoting

  • Repetitive overuse

  • Trauma from a fall or accident

  • Age-related wear and tear

Accurate Diagnosis is Key to FAI Treatment Success

FAI is often diagnosed based on symptoms and a physical exam, along with Xray or MRI. At NYDNRehab, we use the highest resolution diagnostic ultrasound imaging to examine the hip in real time, with the patient in motion and providing feedback. Ultrasound allows us to see the extent of damage, as well as the limitations it imposes on movement.

We also use computer assisted 3D motion analysis, along with other assessment tools, to measure and quantify the quality of hip movement pre-treatment, and periodically throughout the treatment process, to confirm and measure progress.

With a thorough and accurate diagnosis in hand, we are able to design a personalized treatment plan, geared to the specific needs of the patient.

Our Unique Regenerative
Technologies Accelerate FAI Healing

Your body has its own innate healing mechanisms, but they sometimes need a nudge to stimulate the healing process. Regenerative technologies help to jump-start healing at the cellular level, for fast and effective recovery with minimal discomfort for the patient.

Focused Extracorporeal Shock Wave Therapy (ESWT)

Focused ESWT technology produces high frequency sound waves to stimulate the body’s own reparative mechanisms. It is especially effective for treating fibrocartilaginous structures like the hip labrum.

Extracorporeal Magnetic Transduction Therapy (EMTT)

EMTT is a fairly new technology that transmits high energy magnetic pulses to targeted tissues. The magnetic waves synchronize with the body’s own magnetic fields, causing a disturbance that triggers a regenerative response. EMTT waves can penetrate deep tissues up to 18 cm beneath the skin’s surface, to target difficult-to-reach tendons, muscles, bones and nerves.

Extracorporeal Pulse Activation Technology (EPAT)

Extracorporeal Pulse Activation Technology (EPAT)

Extracorporeal Pulse Activation Technology (EPAT)

EPAT, also known as defocused shock wave therapy, uses acoustic pressure waves to enhance blood circulation to targeted tissue, to stimulate cellular metabolism and accelerate the healing process.

High Energy Inductive Therapy (HEIT)

HEIT uses electromagnetic fields to penetrate cells, tissues, organs and bones, to reactivate the electrochemical function of cells and cell membranes.

NESA Neuromodulation Therapy

NESA Neuromodulation Therapy

The NESA device generates an algorithm that delivers a biphasic low-frequency electrical current via semi-electrodes attached to the hands and feet. It emits a series of intermittent and cyclical stimuli that travel through autonomic neural pathways, restoring optimal neural signaling to the brain.

INDIBA Radiofrequency Therapy

INDIBA converts electrical current into a stable frequency of 448 kHz, designed to increase the exchange of ions in damaged cells. The current evokes a regenerative response that accelerates healing.

INDIBA Radiofrequency Therapy

Ultrasound Guided Injection

Injection therapies like platelet rich plasma (PRP) and prolotherapy use natural/neutral solutions that stimulate cellular repair by either nourishing or irritating the targeted cells. Guidance by ultrasound ensures that the injected substances hit their mark, for maximum effectiveness.

Focused Shockwave Therapy

Platelet Rich Plasma (PRP)

PRP therapy uses a sample of the patient’s own whole blood, which is spun in a centrifuge to extract a high concentration of platelets. When injected into damaged tissues, PRP initiates tissue repair by releasing biologically active factors such as growth factors, cytokines, lysosomes and adhesion proteins. The injected solution stimulates the synthesis of new connective tissues and blood vessels. PRP can help to jump-start healing in chronic injuries and accelerate repair in acute injuries.

Proliferation Therapy, aka Prolotherapy

Prolotherapy uses a biologically neutral solution, often containing dextrose, saline or lidocaine. The solution irritates the affected connective tissue, stimulating the body’s own natural healing mechanisms to encourage growth of new normal ligament or tendon fibers.

Electromagnetic Transduction Therapy (EMTT)
Prolozone Therapy

Prolozone Therapy

Prolozone therapy is a new regenerative needling procedure that takes Prolotherapy to the next level. With prolozone therapy, a combination of procaine, anti-inflammatory medications, vitamins, minerals, and a mixture of ozone/oxygen gas is injected into joints or tissues that have been injured or have degenerated. When performed under ultrasound guidance, Prolozone therapy quickly reduces pain and inflammation while jump-starting the healing process.

Ultrasound Guided Dry Needling

Dry needling targets myofascial trigger points that may contribute to FAI pain and stiffness. Ultrasound guidance ensures accuracy, to minimize pain and discomfort for the patient.

    Femoroacetabular impingement (FAI)
    Femora Acetabular Impingement ( FAI) is a relatively new hip joint diagnosis, which produces pain mostly in active individuals or people with predisposing occupations. The condition itself is not new at all, however current understanding of its pathology came with recent advancement in skeletal imaging.In this condition bony conflict between anato the hip cartilage.
    This condition is a precursor of hip arthritis( arthrosis).

    Patients experience sympto sharp pain in the groin after sporting activities.

    The sports, which usually lead to FAI, are: soccer, hockey, martial arts, ballet and yoga.

    This is a list of anators:

    • Congenital hip dysplasia
    • Prominent femoral head-neck junction
    • Elliptical femoral head
    • Femoroacetabular anteversion
    • Femoroacetabular retroversion
    • Coxa valga
    • Coxa Varum
    • Coxa profunda
    • Protrusio acetabulum

    Other predisposing facto distant trauma resulting in alteration of biomechanical relationship in the kinetic chain.

    The progression of this disease is interesting occurrence. One may ask himself that if all anatoms in the second decade)?
    The answer is simple. In FAI congenital bone anomalies are varied in combination of it’s severity and overplay with joint and movement dysfunction in other regions of the body. Majority of people with these congenital anato the hip with congenital imperfections.

    Many people with FAI suffer from back pain and herniated disc disease for years prior toms of hip pain. Majority of these patients are operated for disc hernia without successful outcomes or only with temporary pain relieve.

    FAI Diagnosis

    The golden standard of radiological diagnosis for FAI is special CT scan series. This is, however only necessary in case surgical intervention is entertained as there is enormous dose of radiation involved in this special procedure.
    Otherwise, a combination of X- ray with MRI or diagnostic ultrasound and clinical examination can be specific enough for treatment.

    Femoracetabular Impingement (FAI) Pain Treatment

    FAI pain treatment depends on precise structural and functional diagnosis as well as consideration of compensator control and the biomechanics of the whole human body.

    Femoraceabular (FAI) pain treatment also depends on careful elimination of provoking movement and postures.
    Video gait analysis is the best technological modality to human eye and therefore biomechanical relationship of all the components of lower kinetic chain cannot be properly addressed without it.

    Please explore our gait analysis page.

    Even with all the complexity of the FAI pain syndrome, conservative care is successful in experienced hands within 6-8 weeks in initial presentation and up to 6 month of rehab in chronic cases.

    Surgical Intervention

    Surgical intervention should only be reserved to professional athletes or very few patients with greater damage of hip intrarticular tissues.
    The surgical intervention does not correct the cause of impaired movement but only remove the bone conflicting anatomy.
    Since data for arthroscopic FAI repairs is relatively new , we can not estimate yet how successful these surgeries are. Especially giving very , very long recovery from this surgery this type of procedure should only be reserved as a last reserve.


    In this instance, an athlete was originally diagnosed with minor quadriceps muscle strain and was treated for four weeks, with unsatisfactory results. When he came to our clinic, the muscle was not healing, and the patients’ muscle tissue had already begun to atrophy.

    Upon examination using MSUS, we discovered that he had a full muscle thickness tear that had been overlooked by his previous provider. To mitigate damage and promote healing, surgery should have been performed immediately after the injury occurred. Because of misdiagnosis and inappropriate treatment, the patient now has permanent damage that cannot be corrected.

    The most important advantage of Ultrasound over MRI imaging is its ability to zero in on the symptomatic region and obtain imaging, with active participation and feedback from the patient. Using dynamic MSUS, we can see what happens when patients contract their muscles, something that cannot be done with MRI. From a diagnostic perspective, this interaction is invaluable.
