Knee Pain Specialist NYC

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 pills and unnecessary surgeries.



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 hip and groin pain. Once the exact cause is determined, an effective treatment plan can be initiated.

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.
