Knee pain

About Knee pain

The human knee is a complex structure, designed to withstand enormous force loads. Knee pain can be caused by a number of factors, including gait deficits and injuries anywhere along the lower kinetic chain. You can avoid surgery with accurate diagnosis and conservative physical therapy. At NYDNRehab, we know knees!

Our Rewards


Knee pain symptoms mostly follow anatomy of the knee. Most non-arthritic knee pain is situated below, above or under the knee cup. Arthritic, meniscal or ligamentous pain is situated on or around inner knee (so call joint line). Symptoms from traumatic athletic overuse, running and etc. have special clinical presentation.

Knee Pain Causes

In addition to sports-related trauma, there are a number of underlying factors that can contribute to knee pain:

Sedentary lifestyle
Overweight or obesity
Poor Age-related wear and tear habits
Mechanical deficiencies in walking or running gait
Repetitive overuse from running and exercise
Long hours spent sitting
Weakness and muscular imbalances in the lower kinetic chain
Poor posture when standing

Most non-traumatic knee pain can be effectively treated with knee physical therapy.



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 to ultrasound, video gait analysis can help us identify faulty movement mechanics that contribute to knee pain. Once the exact cause is determined, an effective treatment plan can be initiated.

3D Motion Analysis with C.A.R.E.N

C.A.R.E.N, our Computer Assisted Rehabilitation Environment is an advanced multi-sensory biomechanics system. It allows us to evaluate human movement in three dimensions for clinical analysis, rehabilitation, and training of motor skills, gait and balance. NYDNRehab is one of the few private clinics to feature C.A.R.E.N in the United States.

3D Walking and Running Gait Analysis

The latest gait analysis equipment has revolutionized the way we assess and quantify gait. 3D analysis lets us view gait in the transverse (rotational) plane, where most running injuries occur. Analysis data helps us identify motor deficiencies and mechanical errors, to eliminate pain, enhance performance and reduce the risk of injuries.

Rehabilitative Ultrasound Imaging (RUSI)

RUSI technology lets us identify motor deficits in the deep muscles of patients with musculoskeletal issues. RUSI gives us dynamic real-time images during movement to accurately identify the root cause of musculoskeletal problems, so we can prescribe appropriate exercises to correct them. NYDNRehab features the latest research-grade RUSI system currently available.

Knee Pain Treatment in NYC

Knee pain can be very uncomfortable and even excruciating, leading some to believe that nothing short of surgery can fix it. However, most non-traumatic knee pain can be eliminated through non-invasive treatment methods.

At NYDNR, we use the latest technologies and innovative therapies to treat knee pain.

Gait Analysis and Retraining

Oftentimes 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 or run to eliminate pain.

Alter-G Treadmill

This gravity-reducing treadmill unloads the knee joint, to facilitate gradual recovery and promote improved gait patterns.

(Computer Assisted Rehabilitation Environment)

C.A.R.E.N’s advanced technology uses a virtual reality environment to train healthy movement patterns and provide real-time feedback to help you move better.

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.

Best Knee Specialist in NYC

If you suffer from chronic knee pain and want to find the best knee doctor in NYC, visit NYDNRehab in midtown Manhattan. Our team of knee pain specialists provide individualized treatment plans to meet the needs of every patient.

DD Robotech

DD Robotech (DDR) is a type of AI-powered robotic training equipment developed by Swiss company Dynamic Devices. It is the first robotic trainer 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.

Anterior Knee Pain Treatment

Anterior knee pain is an injury of the knee in which pain is experienced at the front and center of the knee. It is the most common form of injury to knee in adolescents and young adults, and in both athletes and non-athletes. Over 9 percent of young, active adults have suffered from anterior knee pain, and it accounts for a quarter of all knee problems treated at sports injury clinics. It is especially common in women and is one of the more debilitating injuries of the knee; if left untreated, it can create chronic disability. Read more…

Knee Pain Treatment

Knee pain is one of the most common physical injuries and has many possible causes. For this reason it’s difficult but all the more crucial to get an accurate diagnosis for treatment for knee pain. Patients may develop knee pain as a result of arthritis, ligament injuries, cartilage injuries, dislocated kneecap, bursitis, or patellar tendinitis. Luckily there is a variety of knee pain treatment options. Read more…

Osteoarthritis knee pain treatment

Osteoarthritis knee pain can be debilitating, and we at the New York Dynamic Neuromuscular Rehabilitation have successfully treated many patients with osteoarthritis of the knee for over 15 years.

Our doctors and staff are careful to devise treatment plans that are specific to our individual patients. In order to successfully treat our patients, we must take their age, gender and living situation and overall health into account. An otherwise healthy 60 year old who’s used to playing sports can’t be treated the same way as a 70 year old who’s been obese for most of her life and has developed co-morbidities besides arthritis. But no matter, who the knee arthritis patient is, they can depend on the skill, compassion and years of experience of our medical staff. Read more…

Knee Pain Specialist NYC

Our treatment of knee joint pain begins with complete ultrasonographic and dynamic evaluation of the kinetic chain of the lower extremity by technological Gait analysis which includes the hip and the foot. The hip and foot misbalance directly affects the knee since foot placement and hip alignment determines movement at the knee. In such cases, repairing movement dysfunctions of hip and foot will reduce stress overload to the knee and encourage its tissue healing. This strategy is combined with direct treatment of the injured knee tendons and other affected tissues. Read more…

Meniscal Tears

Meniscal tears are a common cause of knee pain. Typically, athletes who play contact sports, are most at risk for meniscal tears. However, anyone at any age can suffer from a torn meniscus. In fact, about one-third of people over 50 will suffer a torn meniscus, with meniscal tears being more common in men than in women. Men are around two and a half to four times more likely than women to develop a torn meniscus. Read more…


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.
