Knee Pain Specialist NYC

About Knee Pain

Your knees are essential to everyday movement, and knee pain can be debilitating, keeping you from doing the things you love. Because multiple structures come together at the knee joint, it can be difficult to pinpoint the exact cause of knee pain, which often leads to misdiagnosis, excessive use of pain medications and unnecessary surgeries. Accurate diagnosis is key to successful knee pain treatment.

Why Knee Pain Treatment at NYDNRehab is Better than Conventional Physical Therapy

Many physical therapists take a one-size-fits-all approach to patient care, using antiquated timelines and cookie cutter exercises that fail to fully rehabilitate knee injuries and restore optimal movement.

At NYDNRehab, we take an individualized approach to every patient and every condition. Using advanced technologies, we are able to accurately diagnose and measure individual parameters for joint angles, force loads, muscle firing patterns and gait. We then design personalized treatment programs based on collected data, measuring progress along the way to ensure full recovery.

Our experience combining innovative treatment methods with advanced technologies makes NYDNRehab the number one choice for physical therapy, chiropractic care and rehabilitation in NYC. We use FDA approved methodologies to successfully treat a broad range of conditions. Our patients include elite athletes and ballet dancers who come to us for rehab and performance enhancement.

  • Repetitive overuse

Accurate Diagnosis Means Successful Knee Pain Treatment

The sports medicine specialists at NYDNRehab are experts in diagnostic musculoskeletal ultrasonography. Diagnostic ultrasound not only enables the doctor to identify the structural causes of knee pain, but it allows your clinician to view the knee region in real time, with the knee in motion. In addition, 3D gait analysis helps us to identify faulty movement mechanics that contribute to knee pain.

By visualizing the knee in motion and gathering quantitative data about gait mechanics, we are able to establish a baseline against which to measure progress. Once the exact cause of knee pain is determined, an effective treatment plan can be initiated and objectively measured for effectiveness.

Specialized Testing for Knee Conditions

Knee pain and dysfunction cannot be effectively resolved using only subjective clinical analysis. Without objective quantifiable data, physical therapy often addresses the symptoms without resolving the underlying cause.

At NYDNRehab, our groundbreaking motion analysis technology and high resolution diagnostic ultrasonography have enabled us to develop a battery of tests that perfectly reveal the dynamic functional pathology of the knee joint.

Our Testing Protocols Include Image

Our Testing Protocols Include

  • Single leg squat stability test with C.A.R.E.N, our computer assisted rehab environment, using perturbation and 3D motion analysis

  • Knee joint stability test using DLEST methodology on C.A.R.E.N

  • KINEO Intelligent load muscle strength assessment

  • Surface EMG to test muscle activation patterns

We Use High-Tech Equipment for Optimal Results

Knee pain can range from mild to excruciating, and many turn to surgery as a first line of treatment. However, most non-traumatic knee pain can be eliminated through the non-invasive treatment methods we practice at NYDNRehab. We use the latest technologies and innovative therapies to treat knee pain at its source and eliminate it for good.

3D Gait Analysis and Retraining
3D Gait Analysis and Retraining

Mechanical deficiencies in walking or running gait can cause the knee to become misaligned, placing undue stress on the structures surrounding the knee and producing pain. We use our state-of-the art gait lab to analyze joint angles and force loads associated with gait, to identify and quantify mechanical deficits and retrain the way you walk and run, to eliminate pain.

Alter-G Antigravity Treadmill
Alter-G Antigravity Treadmill

Our gravity-reducing treadmill unloads the knee joint, to enable retraining of gait patterns without placing undue stress on injured structures. This approach speeds recovery by allowing gradual reloading of the knee and gradual improvement of gait patterns.

Computer Assisted Rehabilitation Environment
(Computer Assisted Rehabilitation Environment)

C.A.R.E.N’s advanced technology uses a virtual reality environment to train healthy movement patterns and enhance sports performance. Real-time feedback is provided to optimize motor patterns, retraining the brain-body connection for efficient pain-free movement.

Blood Flow Restriction Training
Blood Flow Restriction Training

BFR makes it possible to rehabilitate injured tissues using much lighter loads, by occluding the blood vessels to elicit a regenerative response in damaged cells. BFR helps prevent tissue atrophy after an injury while protecting damaged structures from overload. It speeds the recovery process for faster return to pain-free activity.

DD Robotech
DD Robotech

DD Robotech (DDR) is AI-powered robotic training equipment that provides neuromuscular and neurocognitive training for patients and athletes with pain and/or reduced mobility in the lower kinetic chain (hips, knees, ankles and feet). DDR is based on linear force impedance robotic technology.

Percutaneous Functional Neuromodulation (PFN)
Percutaneous Functional Neuromodulation (PFN)

PFN is a new methodology for pain control and muscle recruitment training to help restore quadricep strength and function. PNF works by delivering electrical signals that activate the nerve, creating a biochemical reaction at the neuromuscular junction that essentially rewires the nerve-muscle connection. PNF is also one of the best noninvasive pain management tools available for ACL physical therapy and rehabilitation.

Physical Therapy for Knee Pain
Physical Therapy for Knee Pain

Physical therapy exercises work to strengthen and rebalance the muscles that support the knee joint, taking pressure off of nerves and connective tissue, and realigning the joint for optimal function.

Ultrasound Guidance Makes Our Injection Therapies More Accurate and Effective

Ultrasound Guided Dry Needling

Ultrasound Guided Dry Needling

Trigger points are tiny knots of muscle tissue that often form near the tendon-bone junction, causing pain and weakness. Ultrasound guided dry needling accurately targets trigger points to elicit a twitch response, instantly relieving pain and tension.

Ultrasound Guided Injection Therapies

Ultrasound Guided Injection Therapies

We sometimes use injection therapies to reduce pain and inflammation, or to elicit a regenerative response in damaged cells. Corticosteroids, platelet rich plasma, hyaluronic acid and other injections may be used when deemed appropriate.

More Treatment Options

Acute Knee Pain

Acute Knee Pain

The best treatment options for acute knee pain depend on the diagnosis. Patellofemoral syndrome is the most common type of acute knee pain.

Treatment options include:

  • A combination of EPAT (Extracorporeal Pulse Activation Technology) and ESWT (extracorporeal shock wave therapy) to relieve pain and balance tension in the quadriceps muscles and the patellar retinaculum.

  • Ultrasound guided dry needling

  • EMTT (electromagnetic transduction therapy) for pain treatment and regenerative therapy

Chronic Knee Pain

  • Physical therapy is the single best choice for chronic anterior knee pain.

Chronic Knee Pain
Preventing Knee Pain and Injury

Preventing Knee Pain and Injury

The best way to avoid knee pain and injury is to remain physically active, moving your body in ways that recruit multiple muscle groups in multiple planes of motion. In addition, you should manage your weight and eat a nutrient-dense diet that provides the building blocks for lean muscle and connective tissue. Bone-based broth is a good dietary source of collagen, which plays a protective role in the knee joint.

If you are already physically active, you can benefit from a 3D gait analysis and/or a biomechanical analysis, to identify and correct any motor deficits that can potentially lead to knee injuries. Runners in particular can avoid knee pain by visiting the NYDNRehab Running Lab.

Keeping your hamstring and calf muscles flexible and strong, and your quadriceps strong and balanced will help you avoid knee pain. You should also maintain strong gluteal muscles and a strong core. Do not allow your foot to over-pronate, and maintain strong foot core muscles. It is critical to fully rehabilitate any injuries to the structures of the lower extremity or the low back, including old injuries that were not fully rehabbed.

We understand that every patient has a unique anatomy, and that each condition has unique characteristics. We tailor our one-on-one treatment plans to the individual patient, and never use cookie cutter approaches.

In addition to restoring strength and range of motion to the structures surrounding the knee, we retrain the brain-body connection, to restore optimal neuromuscular recruitment patterns that are often disrupted after an injury. By doing so, our athletes are able to return to sport safely, with reduced risk of re-injury.

    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.
